An improved plunger lift apparatus having an internal orifice, nozzles and exit apertures. The present invention relates to an improved plunger lift apparatus for the lifting of formation liquids in a hydrocarbon well. More specifically the improved plunger consists of a plunger apparatus that operates to propel one or more jets of gas through one or more internal orifices and/or nozzles, out through an aperture and into the liquid load formation, thereby providing a momentum transfer of the gas into the liquid load and causing a gaseous and turbulent aeration to the formation during lift. This action allows a large liquid formation load to be carried to the well top by the plunger at an increased level of efficiency resulting in an improved well productivity level.

A manual scuff mark removal tool for removing random scuff marks from floor surfaces has an angulated head with a pad support block which has a bottom surface and a front edge surface and defines toe and heel corners and edges. A handle projection is defined by the head and is oriented in obtuse angular relation with the pad support block and defines a handle receptacle receiving a handle with a hand grip. A weight is preferably encapsulated within the head for continuously applying a weight induced downward force to a floor during scuff mark removal. A replaceable pad is secured to and covers the bottom surface, front edge surface and the toe and heel corners of the pad support block and by selectively positioning the head of the tool, selected portions of the pad engages the floor surface being cleaned.

The washing machine comprises a housing; a tub provided in the housing and holding washing water therein; a drum rotatably mounted in the tub and receiving laundry therein; and a lifter mounted to an inner surface of the drum to lift the laundry while rotating along with the drum, wherein the lifter is formed to have a nonlinear shape, and wherein the lifter is oriented such that a centerline thereof forms a predetermined angle with respect to a rotational axis of the drum.

The rotor of a hybrid aerodyne for producing lift by rotating during a stage of vertical flight and then for being held stationary and stored longitudinally during a stage of cruising flight has at least one single-blade with a counterweight. The length of the active blade that generates lift of the rotor while rotating is significantly shorter than the length of the radius of the rotor. The portion that carries the active blade that makes the connection between the active blade and rotor mast is structurally rigid. The rigid portion that carries the active blade presents a cross-section optimized to provide zero or almost zero lift and very little aerodynamic drag while the rotor is rotating. The assembly is hinged about a transverse axis perpendicular to the vertical axis of the rotor and substantially on the vertical axis of the rotor mast.

A dual drive drywall lift system for efficiently lifting a panel either manually or through an external motor. The dual drive drywall lift system generally includes a lifting unit including at least one telescoping member, a first drive unit mechanically connected to the lifting unit, wherein the first drive unit selectively extends and retracts the telescoping member(s) outwardly via a manual force input member and a second drive unit mechanically connected to the lifting unit, wherein the second drive unit selectively extends and retracts the telescoping member(s) outwardly via a powered force applied to the second drive unit.

The invention belongs to the technical field of repair of high-speed railway ballastless tracks and particularly relates to a lifting repair method for a ballastless track with a settled curved section. The lifting repair method for the ballastless track with the settled curved section comprises the steps that after a lifting unit and the lifting quantity of the curved section of the ballastless track are determined, a high-pressure grouting device is adopted, grouting is conducted on a lifting hole and a filling hole in sequence according to determined equipment parameters, hole positions, a grouting sequence, a grouting rhythm and construction steps with a triangle balance lifting method at a certain pressure, grouting materials are injected into the position below the ballastless track through a grouting pipe installed in the grouting hole in advance and are rapidly cured, longitudinal displacement change, transverse displacement change and vertical displacement change of the track are monitored in real time through a measuring device, and then accurate lift, balance supporting and rapid repair are conducted on a settled ballastless track structure. According to the lifting repair method for the ballastless track with the settled curved section, construction is rapid, practicability and reliability are achieved, cost is low, and the method which is rapid and convenient to implement, practical and economical is provided for solving of the problem of settlement of the ballastless track within skylight time.

A golf ball lifter and retriever made of a flexible, resilient, yet relatively stiff elastomeric plastic or rubber material for durability and function during repeated and extended use. The lifter may be mounted on the butt end of a club grip and is generally cylindrical having a ball engaging end portion and a club grip engaging end portion separated by a solid wall, the ball engaging end portion having four tapered fingers formed, by lengthwise slits extending inward from the ball engaging end of the lifter.

The tapered fingers have gripping lips at the ball-engaging end. The slits are formed by the longitudinal edges of the tapered fingers and end in a circular bore acting as an edge joint and have two parallel circumferential ribs extending inward from the inner wall of the fingers for gripping the golf ball, the first rib being an inward extension of the gripping lips.

The invention discloses a material supporting mechanism and a laser pipe cutting machine with the material supporting mechanism, and relates to the field of laser cutting. The material supporting mechanism includes a supporting mechanism, and the top of the supporting mechanism is provided with a material supporting mechanism. Diameter wheel, the top of the variable diameter wheel is the material support channel, the material support channel is used to place the pipe to be cut, there is a variable diameter wheel shaft between the opposite sides of the variable diameter wheel, and the two ends of the variable diameter wheel shaft pass through the clamp spring and the variable diameter wheel. The outer side of the diameter wheel is detachably connected; the outer side of the diameter reducing wheel is provided with a pull ring spring pin, and the outside of the diameter reducing wheel is provided with a diameter scale, and there are several positioning holes on the diameter scale. When determining the diameter of the pipe to be cut, Determine the positioning hole corresponding to the current diameter, rotate the reducing wheel, change the length of the reducing wheel shaft until the current positioning hole is fixed with the spring pin of the pull ring, and the size of the supporting channel is adapted to the diameter of the pipe to be cut. The invention can effectively support the pipes to be cut with different pipe diameters, and effectively improve the cutting precision.

A hydraulic borehole mining system controlled and operated above-ground includes a high-pressure cutting nozzle that is delivered to an underground resource body through a relatively small diameter borehole. A series of water and air fluid streams at various pressures are delivered to the resource body, and the target resource is disaggregated and/or fluidized and conveyed back to surface via the hydraulic borehole mining pipe which serves as the conveyor of the system. The mining pipe is used to transport a high-pressure stream of combined air and water fluids that have been directed and aligned into laminar flow to a focused water jet cutting head. The central bore of the mining pipe brings the slurrified resource to the surface. The mining pipe transports the slurry via hydraulic airlift, fluid eduction or both.

A plate cleaner for a printing press includes a cleaning head and a nozzle mounted on the cleaning head for directing pressurized fluid toward the plate cylinder of the printing press. The nozzle directs the pressurized fluid at an acute angle to a tangent to the cylinder in a direction opposite to the rotation of the plate cylinder. The cleaning head is provided with a suction port for removing contamination from the plate cylinder. The nozzle is located outside of the suction port.
