The guiding apparatus is physically moved until it is located on the camera axis, which is the mill axis. The guiding apparatus is then remounted in the mill.

Abstract: A fish hook setting device is described in which a hook setting device is attached to a fishing line in such a manner that it may be actuated by a fish attempting to remove bait from the hook on a fishing line. The device allows the fishing line to slacken a little before snapping into the fish hook setting operation so that the chances of getting the fish hook “set” in the fish's mouth are good.

Abstract: A sound producing rock having a matching body and a cap such that the cap is supported above the body in a spaced relationship to give the illusion that the cap and body are a monolithic structure. The cap and body are produced by sawing the cap from the body. A cavity is formed in the body by drilling a borehole in the body which extends downwardly from the flat body surface. A speaker is mounted in the cavity to project sound upwardly against the flat surface of the cap so that sound is projected outwardly from the space formed between the cap and body.

Abstract: A pinion for mounting rolls thereupon for reducing rod or wire in a rolling mill wherein said pinion has a pair of hydraulic pressure chambers formed therein which cause a threaded plug in a cavity in said pinion to undergo lateral movement to expand the pinion to engage a roll mounted on said pinion, and thence to cause a clamp to laterally clamp a roll against an abutment formed on the pinion to clamp the roll on the pinion once the plug has undergo lateral movement.

Abstract: An expanding hub assembly for a capstan drive for a steel mill comprising a modified spline having a large cylindrical surface area for mating with an installed mill roll. The cylindrical surface is interspersed with a series of evenly spaced shallow axial troughs formed therein for mating with a series of shallow projecting splines on a mounted mill roll. The hub is hollow and an expansion device is present in the hollow hub for expanding the mating surface of the hub.

Abstract: A primary support for a tunnel roof comprising elongated lagging members which are “extruded” from tubes forming a shield for a tunnel boring machine. The lagging is inserted into the tubes at different times so as to avoid having the ends of adjacent lagging members coincide. As the tunneling machine progresses in the direction of boring, the lagging members emerge from the shield tubes to form a primary tunnel roof lining. Ring beams or arc beams may be installed as required by rock bolts or other fastening devices.

Abstract: A golfing aid for golfers who are unable to stoop which allows a golfer to insert a golf ball and tee into the aid in a contacting relationship so that the tee protrudes from the base of the aid a preset distance. The aid has an elongated handle to allow the ball and tee to be pushed into position so that the tee penetrates the ground while the ball is captively held in contact with the tee. The handle is next released and contact with the ball ceases so that the aid may be removed from the ball and tee without dislodging the ball from the tee.

Abstract: A manhole for a storm sewage system comprising a structure having at least two outwardly extending substantially vertical flat panels projecting outwardly from the exterior surface a predetermined distance on opposite sides of the base portion of the manhole.

Abstract: A cable cutting device having one handle of the cutter placed parallel and closely adjacent to the cable which is to undergo cutting. When a cable is about to be cut, the cable and the handle of the cutter are placed in a side by side relationship and both the cable and handle of the cutter are grasped by the user. The remaining handle is attached to a ratchet mechanism in the cutter and is oscillated to drive the cutter by means of a ratchet device to cut the cable which is still being grasped by the user. Now, the severed cable may be suitably disposed of in a controlled and safe manner. If the user is a utility lineman, the safety associated with the above operation cannot be overemphasized.

Abstract: Described herein is a flexible battery pack for powering downhole electronic equipment. The pack includes a plurality of electrochemical cells connected and tied together in a stacked working relationship by a pair of semi cylindraceous encapsulating shells which form a primary containment for the electrochemical cells. The shells are secured at each end to a cylindrical insulating plug which secures the shells together. The shells preferably comprise a glass fiber reinforced plastic material. The primary containment is then sealed in a stainless steel tube which is provided to hold the interior components in place during operation. The encapsulating members are provided with an internal grooved recess which receives and holds any electrical conductors which may be required for operation of the battery pack.

Abstract: An outdoor lighting device composed of suitable natural rock wherein the rock itself provides a suitable housing for a light source, and the rock is also used to function as a reflector-diffuser to provide a “soft” light for illuminating outdoor gardens, etc.

Abstract: A roller for a steel mill entry guide in which pockets are formed in at least one of the flat annular surfaces on the side of the roller. The pockets are used to intersect a stream of moving fluid projected at the surface of the roller containing the pockets to force the rollers to rotate whilst no work is passing through the guide. The pockets are of a rectangular shape and are easy to fabricate and have no preferential direction of rotation.

Abstract: A sandwich type insulation for electrical machinery comprising a laminate of a polymeric material such as polyimide which contains particles of an inorganic corona resistant material, said polymeric material being bonded to mica paper consisting of mica, wherein said mica paper may be impregnated with polymeric resin containing particles of inorganic corona resistant material.

Abstract: An internally expanding cutting device is used for severing large cylindraceous objects in two. The device comprises a spider mechanism in which a series of radially extending arms are attached to a central hub. The spider is arranged to be mounted on a base member so that the spider mechanism is free to rotate. A series of self propelled cutting wheels are mounted on the arms of the spider to allow the cutter wheels to contact the interior wall of the cylinder to be cut. The cutting wheels are arranged to drive the spider in a rotational manner while the cutter wheels are progressively pushed outwardly to deepen the cut. Each wheel follows in the track of the previous cutter wheel until the cylinder is severed.

Abstract: A hairbrush, the surface of which changes colour with temperature, is used to improve the set of human hair during a grooming process. The bristles of the brush may be of a colour temperature dependent nature as well as the surface on which the bristles are mounted or protrude.

Abstract: An assembly for producing a finished shape for a rod after the last rolling stage of a multi strand steel mill. This apparatus provides an operation for correcting minor surface irregularities and shape distortion of the rod as it exits from the finishing roll stand. The apparatus consists of four rollers mounted in an assembly which resembles a roller entry guide except that the rollers are capable of producing changes in shape of a work product passing therethrough. The orientation of the roller axis is slowly and constantly changed to prevent wear distortion of the rollers which may result when the rollers are required to roll a malformed product from fixed roller axes. The rollers may be driven in some circumstances.
