An electric power monitoring system includes a source monitor for measuring momentary power output of an electric source supplying electric power to a power distribution system having at least one electric load. The momentary power output is compared with a reference load capability for the electric source to determine the ability of the electric source to support additional load, and load capability data is transmitted based on the load capability. At least one load control receives the transmitted load capability data and controls the supply of power to the at least one corresponding electric load based on the load capability data.

A compressor vane or compressor blade is provided. The axial flow compressor includes an axial direction, a radial direction, a compressor hub and a compressor casing. The vane or blade includes an airfoil with airfoil sections having a span, a chamber line and a leading edge at which the chamber line includes a leading edge blade angle with the axial direction of the compressor and a trailing edge at which the chamber line includes a trailing edge blade angle with the axial direction of the compressor. The airfoil sections are stacked at the leading edge on a straight line extending along a radial direction of the compressor from the compressor hub towards a compressor casing and in that the leading edge angles of the airfoil sections vary along the span and are larger for airfoil sections close to the hub and close to the wall than for mid-span airfoil sections.

According to the invention, better requests resulting in the load being under a first predetermined limit are admitted. If a bearer request would result in the load being over the first predetermined limit, the admission control entity tries to make room for the bearer request, i.e. release resources without degrading the quality of service (QoS) provided for the existing bearers. The admission control entity may perform this by adjusting power control parameters, handover control parameters, or both. If the admission control entity is able to make enough room for the new bearer or bearers, the request is admitted.

An apparatus and a method for sorting workpieces (204) includes multiple conveyors (201, 202), a scanner (208), an offloading device (216), a workpiece processor (218), and a computer (210). The computer has instructions for carrying out a method for sorting that includes obtaining the physical parameters of the workpiece by scanning the workpiece, obtaining an updated distribution of a physical parameter of a population of workpieces, obtaining an updated loading on each conveyor, obtaining the workpiece processor's capacity, obtaining a processing parameter indicating the required amount of workpiece processing to be performed, and obtaining each conveyor's speed. This information is used to place the workpiece on a conveyor in a manner that is calculated to utilize the optimum amount of workpiece processor capacity, while at the same time maintaining an even belt loading. The computer is in communication with conveyor speed drivers (250, 252) and the offloader to adjust retention time and / or conveyor loading.

A foot-assisted snow shovel with a stepbar whereas the user presses down with the foot to initiate the scooping of snow, a guide bar which travels in parallel with the stepbar, a guide channel which the upper pivot points of both stepbar and guide bar are constrained within, a linkage member which holds the stepbar and guide bar parallel throughout their movement, and a scoop clevis fastened to the rear of the snow scoop to which both stepbar and guide bar attach. The parallel configuration of the stepbar and guide bar maintains the scoop in a horizontal orientation during the scooping and the tossing of snow. A protruding feature of the upper end of the guide channels allows the scoop to remain level maintaining its load of snow even as the machine is tilted backward. Rigid uprights with grips provide the framework and the means of handling and control for the user.

A corrugated paperboard wraparound blank for forming a shipping case is provided, including five wall panels and four sets of end flaps connected via fold lines, at least two sets of stacking tabs, and at least two corresponding sets of receiving slots for receiving the stacking tabs. The wraparound blank is formed of a heavier material than a conventional blank, which would typically be difficult for automatic packaging equipment to form into a case, but the fold lines are creased with optional perforations or scoring. An optional modification aiding folding is presented for conventional case packers. The heavier fiberboard better supports and protects an inner product, such as cartons or paper bottles of liquids and reduces damage to the cap and neck. The heavier material in combination with the stacking tabs allows an increase in stacking height, thereby reducing transportation costs.

A method and system are disclosed for moving material past an obstacle and / or for moving materials in areas of limited space. A user can move so that the area and space required to move an object is reduced. A user can utilize the system and method to load an object and then tilt the object to be moved so that the area needed to move an object is reduced. After the object has been tilted, a user can move the object in locations characterized by various physical restrictions such as limited height, width, and length dimensions that do not ordinarily allow for movement of larger sized objects.

A power supply for welding, cutting and similar operations includes a dual two-switch forward converter. The converter has two inverter circuits coupled in parallel but controlled to provide output power in an interleaved fashion. To avoid “walking” of the circuits (which could result in different duty cycles and imbalance of the load sharing), control signals are determined and applied to a first of the inverter circuits, and “on” times of the first circuit is monitored, such as by augmenting a counter to determine the number of clock cycles the first circuit is “on”. The same duration is then used for commanding output from the second inverter circuit. The duty cycles of both circuits is thus ensured to be the same regardless of changes in the total output power.

A method of spooling a crane rope (2) onto a crane drum through a crane rope spooling system (1) from a reel (31) under a predetermined back tension is described and includes the steps of:unspooling the crane rope (2) from a reel (31) and passing the crane rope through a tensioning system (10) comprising a primary back tensioner (12) and a secondary back tensioner (16);gripping the crane rope (2) within the secondary back tensioner (16) and thereby preloading the crane rope (2) with tension prior to the crane rope (2) passing through the primary back tensioner (12); andapplying a predetermined back tension to the crane rope (2) with the primary back tensioner (12) as the crane rope (2) is being spooled onto the crane drum under the predetermined back tension.A crane rope spooling system (1) for spooling crane rope (2) onto a crane drum under a predetermined back tension is also described, said system (10) comprising a tensioning system (10) comprising at least a primary back tensioner (12) and a secondary back tensioner (16) and a reel (31).

A gasket for providing a gas and fluid tight between parts of an internal combustion engine, for example around a combustion chamber opening, is provided. The gasket includes a functional layer with a full embossment spaced from the combustion chamber opening. A stopper layer is attached to the functional layer adjacent the combustion chamber opening. After attaching the stopper layer to the functional layer, half embossments are simultaneously formed in the functional layer and the stopper layer adjacent the combustion chamber opening. The aligned half embossments are together referred to as a half-stop. The half-stop maintains the load on the stopper layer, limits compression on the full embossment, and protects the full embossment from combustion gases when the gasket is compressed between two parts of the internal combustion engine.

A valve is provided. The valve includes a body provided with fluid passages for circulating fluid therein. The body has a body interface with ports connected to the fluid passages. The valve also includes a valve element having a valve element interface facing the body interface. The valve element can move between different positions so as to permit or obstruct communication between the fluid passages. A biasing element biases the valve element interface against the body interface. A load varying mechanism is provided to load the biasing element with different sealing load forces according to the different positions of the valve element. The sealing load force applied on the rotor is thus decreased during rotation, reducing friction between the valve body and the valve element.

A secondary packing arrangement is provided for use with a well having a reciprocating pump and polished rod, and in combination with a stuffing box, the stuffing box being modified. Packing seals, a barrier fluid and a pressure transmitter cooperate with modified stuffing box components to regulate the pressure on either side of a packing seal. The barrier fluid is contained above the packing seal, with well fluids and accompanying pressures being contained below the packing seal, such that if leakage occurs, relatively clean barrier fluids are leaked instead of well fluids. The pressure across the packing seal is substantially balanced across the packing seal, or the well fluid side pressure is less than the barrier fluid side, thus reducing the occurrence of leakage and extending the life of the packing seal. Sources for the well fluids cooperating with the pressure transmitter include the well's flow line and casing.
