A container for the dispensing of wire or cable has an external carton which receives a reel of cable supported by two caddies. Each caddy has an inwardly extending substantially cylindrical bushing which is received in a central hole of a respective cable reel flange. The cylindrical bushings are disposed on an axis which is a first distance from an upper surface of a bottom panel of the carton. The largest radius of the reel flanges is preselected to be smaller than this first distance such that the reel may freely rotate inside of the carton on the bushings. Cable is pulled through a slot in the carton's front panel. Left and right panels of the carton each have an arbor hole formed therein which may receive an axial rod, the rod also extending through the reel and caddies. The axial rod may be used to join two or more cartons together and may further serve as a support for attachment to a dolly, hand truck, or four-wheeled cart. In one embodiment, cable may be pulled through one or more pass-through slots formed in the tops and bottoms of stacked containers, such that cable from multiple containers is drawn through one slot on the top of the stack.

To miniaturize an engine, to concentrate heavy masses and to reduce friction loss of a balancer. An engine crankcase structure in which a crankcase is vertically partitioned into an upper case and a lower case, each journal supporter is formed in the upper case and in the lower case so that the rotational axis of a crankshaft is located on a partition face of the crankcase in parallel with a direction of the width of the body. The crankshaft is supported so that the crankshaft can be rotated. An oil filter is directly attached to the lower case. An oil cooler and a secondary balancer are arranged in the front of the lower case.

A process is provided for recovering heavy minerals from aqueous oil sand tailings, the oil sand tailings having heavy minerals, other coarse solids such as silica, fines, residual bitumen and water, including desliming the oil sand tailings in a desliming means by removing a portion of free fines and residual bitumen from the oil sand tailings; attritioning the oil sand tailings in an attritioner to remove adhered fines and residual bitumen from the heavy minerals and other coarse solids; and subjecting the deslimed and attritioned tailings to separation in a separation means to separate the heavy minerals from the other coarse solids present in the deslimed and attritioned tailings and produce a concentrated heavy minerals fraction.

It is an object of the present invention to provide a multi-piece rim which does not need much labor for supporting, and does not increase the number of components to be managed and the number of needed tasks.The present invention constructs a lock ring (40) to be fitted in the groove (11a) of a gutter band (11), which ring is divided in a plurality of portions (41, 42) being coupled at each end (41a, 42a) thereof by a flexible coupling member (43). Alternatively, a lock ring (140) is formed into a substantially C-shape being manufactured by cutting a part of a circular ring, and comprises a first portion (141) wherein a length of a chord at the cut portion is substantially equal to the diametral of a hub, and a second portion (142) having a shape corresponding to the cut portion of a circular ring in the first portion.

An X-Y both-way unmanned remote control climbing robot is characterized by comprising a main machine, a climbing device and a rescuing device, wherein the climbing device and the rescuing device are arranged in the main machine, the climbing device comprises an X-axis steel wire rope and a Y-axis steel wire rope fixed to the top, and the X-axis steel wire rope and the Y-axis steel wire rope are connected with corresponding winding devices and corresponding electromagnet clamping devices in the main machine respectively; and the winding devices are rollers driven by motors, the steel wire ropes are wound on the rollers, and the main machine can be driven to move in the corresponding direction during rotation of the rollers. The X-Y both-way unmanned remote control climbing robot has the beneficial effects that a winding type rope collecting climbing type structure is adopted, climbing force can be improved while climbing stability is guaranteed, and more functions can be easily achieved in the robot; stepping type advancing of the robot can be achieved through cooperation of electromagnets and the winding devices, steel wires wound on the winding devices can be released in time, and it is avoided that due to too many wound steel wires, the size of the robot is large, and the mass is large.

The invention relates to a construction method of mass concrete temperature decrease and crack prevention by utilizing a thin-walled corrugated pipe circulating water system, which comprises the following steps: (1) selecting circulating water pipes: selecting thin-walled iron-sheet corrugated pipes as the pipeline materials for arranging circulating water pipes; (2) arranging a circulating waterpipe system: in the process of binding a reinforcing cage, installing and fixing the corrugated pipes to the reinforcing cage in a spiral or laminated way according to the structure form of a mass concrete, wherein, the distance between layers is from 500 mm to 2000 mm, the distance between rows in the layers is also from 500 mm to 2000 mm, and providing a water inlet pipe and a water outlet piperespectively connected with the corrugated pipes on the upper part of the mass concrete; (3) arranging temperature measuring points; (4) pouring the concrete; and (5) keeping maintenance. The construction method has the advantages of obvious effect on the temperature decrease and crack prevention of the mass concrete, low cost, simple operation, convenient and quick construction and convenience in the connection of the corrugated pipes.

The invention provides a method for casting a multi-box hot pot, and belongs to the technical field of iron pot casting. According to the hot pot, partition plates are cast at first, and then the partition plates and a pot body are in melting combination to achieve seamless connection. The method includes the main steps that (1) the partition plates are formed; (2) the partition plates are placed into a mold to be polished; (3) the pot body and the partition plates are combined; and (4) cooling molding is performed. By the adoption of the method, the hot pot is made of cast iron which is natural, environmentally friendly, safe and stable in performance, the hot pot is divided into a plurality of small boxes through the partition plates, and the partition plates and the pot body are subjected to casting molding directly without welding; hence, hazardous substances at the welding position can be prevented from entering human bodies along with the hot pot, corrosion of the connecting portion between the partition plates and the pot body due to cooking the hot pot for a long time is prevented, the phenomenon of being tainted by other odors between all the small boxes is effectively avoided, and hot pot quality is improved. Moreover, the pot body is separated by the partition plates, each person can use his / her different small boxes, different hot pot materials can be boiled, and therefore the hot pot not only is sanitary but also can be used for boiling different kinds of food at the same time.
