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: This invention relates to the production of a useful eutectic layer formed on a zirconium alloy or a titanium alloy substrate. The layer is formed by the surface contact with a beryllium strip being held in intimate contact with the surface of the zirconium or titanium alloy substrate while the zirconium or titanium alloy and the contacting beryllium strip are heated in an inert atmosphere to a temperature which is above the eutectic melting point and is held constant at that temperature for a predetermined time. At the prescribed time, the materials are allowed to cool and the beryllium strip is "removed" from the "surface" of the zirconium or titanium alloy substrate and the newly formed zirconium-beryllium or titanium-beryllium alloy eutectic is formed in the surface of the zirconium or titanium alloy substrate.

Abstract: This application relates to a grinding machine which is capable of performing two controlled grinding operations simultaneously on a rotating workpiece.

Abstract: A steel billet is reduced to a bar in a hot steel mill rolling operation by plural reductions successively produced by passage of a workpiece through a series of reducing mill stands. Each mill stand produces a workpiece having a rhombic shaped cross sectional configuration during a reduction passage through each mill stand. The plastic deformation of the workpiece produced by the rollers in each mill stand not only reduces the cross sectional area of the workpiece but also reverses the major and minor axes of the rhombic cross section of the workpiece during passage through each mill stand.

Abstract: An interceptor tank for primary treatment of rainwater runoff which may contain a variety of pollutants. The tank is a multi-chambered device which provides a partial separation of the pollutants contained in the effluent rainwater. A bypass system prevents overload of the tank during periods of heavy inflow conditions. Under low inlet flow conditions, an orifice in the bypass system functions to allow the effluent to drop into the first chamber which serves as a trash and debris collector. The effluent passes from the first chamber to a second chamber where free petroleum based products are separated and held. The effluent from the second chamber passes into a third chamber where sediment is separated from the effluent. The effluent from the third chamber may be fed back into the bypass conduit to be fed into a sewer system or alternately through an aperture in one of the exterior walls of the last chamber to a sewer.

Abstract: A slitter for a steel mill comprising a pair of spaced rollers having a predetermined surface configurations. A deeply grooved steel workpiece is passed through the gap in the spaced rollers and each section of the workpiece (between the grooves) is twisted through a small angle. Because each section is twisted in the same direction, the workpiece fractures along each groove in the workpiece.

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.

The device in its simplest form comprises three interdependent members, two storage members which stack one upon the other in its working configuration, and a filtering member which is attached to the bottom of the upper storage member for filtering tap water contained in the top storage member. When desired, the top member may be inserted into the lower member in a nested configuration for convenience when travelling.

Abstract: A fanless salient pole DEM is provided with annular shrouds fitted to the stator ends in close juxtaposition to the rotor to isolate the rotor from atmospheric pressure during operation of the DEM.

Abstract: An entry guide device comprising a funnel shaped inlet member in close proximity to three adjustable rollers mounted at 120.degree. around the axis of work moving through the entry guide device. The adjustable rollers are actuated to move in concert so as to be able to accommodate a work product of difference diameters, whilst preserving the concentricity of the three rollers. The funnel shaped inlet member is replaceable to accommodate for wear and provision is made to calibrate the position of the three movable rollers with a calibration device which may be conveniently inserted into the device to check and calibrate the three rollers for concentricity. This entry guide device is ideally suited for guiding a work produce having circular, triangular or hexagonal cross-sections.

Abstract: An assembly for producing a finished shape for a rod after the last rolling stage of a multi stand 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.

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: This apparatus is directed to reduction in emitted windage sound in dynamoelectric machines by detuning cavities formed in the ventilation spaces of the machine.

Abstract: A rotor for an induction motor of the squirrel cage type wherein the rotor bars are exposed to a resilient anti-sparking compound in the rotor slots of the machine. The rotor bars are provided with a longitudinal slot to permit the insertion of the anti-sparking compound after assembly of the squirrel cage rotor. Alternatively, the laminations may be shaped to produce a longitudinal groove in the rotor bar slot to permit the insertion of the anti-sparking compound in the groove so produced. Of course, both the rotor bar and the rotor slot may both be provided with complimentary slots adjacent one another in which the anti-sparking compound may be injected.

Abstract: This invention relates to a package which functions to receive and secure other packages. The package is analogous to a magazine which may be loaded and contain several identical cartridges in a serial fashion. Because the cartridge packages have unified shape and size, the impact of a number of cartridge packages in lined formation in the magazine package is an effective marketing tool.

Abstract: A warning device for the detection of a bearing malfunction in wheel assemblies of large commercial vehicles such as tractors and semi-trailers is disclosed. The warning device is preferably mounted on the stationary axle inside the wheel housing adjacent the brake mounting assembly to remain stationary. The device includes a probe which protrude outwardly so as to have a sensing end extend until it is a predetermined instance from the rotating brake drum, say 25-50 thousandths of an inch. As long as the brake drum is running true, the distance between the sensing end of the probe and the inner braking surface of the brake drum remains constant. If either wheel bearing becomes incapacitated for some reason which permits the brake drum to run out of true, the inner braking surface will contact the end of the sensing probe which activates a signalling device in the cab of the vehicle to alert the driver of the presence of a dangerous condition.

Abstract: Stator bars and stator coils (winding elements) for a large dynamoelectric machine which are to be permanently placed in the slots of the magnetic core of the machine are wrapped so as to be surrounded on three sides with an elongated sheet of an elastomeric substance. A stretching device is attached to the two overlapping edges of the elastomeric sheet in such a manner as to be able to stretch the sheet around the winding element and thus reduce the thickness of the elastomer. The winding element surrounded by the stretched layer of the elastomeric substance is placed in a selected stator slot and the stretching device is detached from the elastomeric material. The elastomeric material attempts to regain its former thickness but is confined to the remaining space between the winding element and the sides of the slot. The offal is trimmed from the elastomeric substance and the winding element remains lodged in the slot.

Abstract: A dynamoelectric machine stator winding element which has a foreshortened end protruding from the stator of the machine when compared to prior art winding elements.
