Abstract: ABSTRACT OF THE INVENTION      An energy absorber (or arrestor) working on the principle of straining an elongated element by pulling it through a tortuous path over rotatable rollers and characterised by the element being of flexible laminar construction.    The flexibility of this element allows it to be formed into a conveniently small coil, the diameter of which being that of an equivalent section rigid element divided by the number of laminae.    The rollers, similarly reduced in diameter, are arranged into two opposed banks which temporarily divide the element into two equal and opposite laminar groups, the angular reactions of which counterbalance each other.    The normally haavily loaded exit rollers are substantially assisted by contact with remote support bearings.    The end of the element is anchored by entrapping two equal groups of laminae, utilising the strain energy principle and retaining the use of the full tensile area.

Abstract: ABSTRACT OF THE DISCLOSURE          In particular compositions, it is advantageous to seek to match the physical properties such as particle size and density of the components and in particular it is desirable to modify the physical properties of magnesium salts of various percarboxylic acid caxboxylates for example particular magnesium monoperoxyphthalate, that have been produced in the processes described in European Patent Specification 27693 and the applicant's Canadian Patent Application Serial No.404,224 filed June 1, 1982, for subsequent incorporation in detergent and/or bleaching compositions.  In the present invention, granules of the magnesium salts are obtained by spraying onto agitated feed particles of the salt a small amount of a dilute aqueous solution of a synthetic poly hydroxy-substituted compound, particularly polyvinylalcohol and drying the resultant agglomerate.  It is especially suitable to carry out the granulation process in a warm air fluidised bed using feed particles of mainly below 200 microns producing eventually a low bulk density product mainly in the range 200-1000 microns.  In a modification of the fluidised bed process, the agglomerating agent used can be an aqueous solution of carboxylated polyvinyl alcohol.

Abstract: "ZERO PRESSURE ACCUMULATION CONVEYOR ~ TRIGGER ASSEMBLY"              Jonathan R. Davis ABSTRACT OF THE DISCLOSURE A live roller zero pressure accumulation conveyor and trigger assembly for sensing the presence or absence of articles on the conveyor are described.  The trigger assembly includes a cam which is mounted to the conveyor for pivotal movement about an axis at or above the axes of rotation of the conveyor rollers, a leg on the cam spaced from the pivotal mounting and extending upwardly between a pair of the conveyor rollers, and a cam roller rotatably mounted adjacent the end of the leg.  The cam roller is rotatable about an axis which is substantially parallel to the axes of rotation of the conveyor rollers.  The cam roller is movable to a first upper position in which the cam roller extends above the plane of the conveyor rollers in the absence of an article and the axis of rotation of the cam roller remains below the plane of the conveyor rollers in the uppermost position, and a second position in which the uppermost portion of the cam roller is urged by an article moving in either direction on the conveyor so that it is substantially in the plane defined by the plane of the conveyor rollers.  Sensing means is responsive to movement of the cam roller for controlling the operation of the conveyor. A plurality of conveyor roller sections having-live rotatable rollers are driven by endless belts and independently rotating torque tubes in each of the sections.  Each of the sections includes one of the trigger assemblies for controlling movement of the rollers in a section.  The conveyor may be operated to handle articles in either a slug or singulation mode

Abstract: ABSTRACT OF THE DISCLOSURE           A system for varying the speed and displacement of a variable-displacement hydraulic motor and for providing a feedback signal which prevents the motor from stalling when an operator tries to reduce the motor displacement below the stall level.  The system is especially useful for operating a hydraulic winch system on a wire rope crane.  A variable displacement hydraulic pump provides pressurized fluid to operate a variable displacement hydraulic motor for lifting loads supported by the wire rope.  The motor speed is controlled by varying the displacement of the pump and/or the motor, with the motor speed generally increasing as motor displacement decreases. The motor could stall if the crane operator decreases motor displacement below a critical value.  A feedback signal coupled to the motor controls the motor displacement to prevent motor stalls.

Abstract: RICHARD H. CARLSON     THERMOSTATIC SWITCH CONSTRUCTION            ABSTRACT OF THE DISCLOSURE           A  bimetallic, disc-actuated,  thermo-static  switch  comprising  a  resiliently deformable actuator disc having an integrally struck actuator arm which extends radially inwardly to a point adjacent to a fixed contact.  When the bimetallic disc is flexed in response to-a predetermined temperature change, it applies pressure to the edge of the actuator disc proximal to the stem of the actuator arm causing the actuator disc to be resiliently deformed and causing the arm to be pivoted on a fulcrum in the switch, thereby causing the terminal end of the arm to move relative to the fixed contact to either open or close the switch.  Since the arrangement is such that the edge of the bimetallic disc exerts pressure on the actuator disc, maximum deformation is imparted to the actuator disc thereby achieving maximum movement of the actuator arm for a given size bimetallic disc, thus permitting relatively small discs to be success-fully utilized.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a security device for use in preventing the unauthorised rotation of a wheel such as a steering wheel, an undriven wheel of a vehicle.  The device is so arranged that while it may allow a limited movement to the wheel it prevents the wheel being turned through more than a fraction of a full turn and thus would prevent a vehicle being driven away or a machine or appliance being turned on, or a boat being steered.  The device comprises a boss plate, two pivoted callipers which wrap around the vehicle wheel and an adjustable calliper. Stops limit movement of the pivoted callipers.  The adjustable calliper slides in a bracket and can be locked in a number of different positions by a padlock engageable in holes provided. An extension of the adjustable calliper will engage the ground or part of the vehicle and prevent unauthorised movement.

Abstract: PROCESS FOR MAKING FISHING LURES AND THE PRODUCT THEREOF PROCESS FOR MAKING FISHING LURES AND THE PRODUCT THEREOF                 ABSTRACT OF THE DISCLOSURE A process for making foll type fishing lures and the product thereof. The process provides a low cost method of making a variety of lures from a common blank, each having accuracy and balance with unique features and actions. A blank is first cut from a sheet of metal and a surface finish thereafter is applied to the blank.  The overall shape of the blank is a truncated oval with a rounded leading portion and a segmented truncated trailing portion.  Within the segmented trailing portion is a slot which divides the blank into symmetrical half segments.  A compound shape is next formed in the metal of the blank by a lateral displacement of the trailing segments which bows the metal.  Displacement of the segments also closes the slot and reduces the surface area of the lure.  The compound shape is then fixed interconnecting the trailing segments at their displaced positions.  The final step is the assembly of remaining hardware to the body of the lure.

Abstract: ABSTRACT                      Apparatus for Cold-molding Structures In an apparatus for cold-molding a structure, it is a rigid framework inflexible to rapid design changes making short production runs of varying design expensive and leading to a one-off system of production.  In this invention a totally new method of construction allows rapid and inexpensive design changes plus substantial labour cost reductions due to the potential application of automation and robotics to the apparatus.  To a central axis of variable length supported at each end by telescopic legs are attached, by means of a collar configuration, adjustable arms and interchangeable plates that hold in place the sheet material to be cold-molded.  The collars can be spaced at various intervals along the axis to accommodate variations in the dimensions of the sheet material to be cold-molded.  The length of the axis determines the length of the structure that can be constructed.  The length of the adjustable arms determines the height and width of the structure.  The plates at the end of the arms can be interchanged to alter the shape of the structure and provide the framework to which the building material (veneers) are temporarily attached during the cold-molding process. A bearing at each end of the cylinder allows the apparatus to be rotated through 360° giving access to all surfaces of the work area from one position. This rotation is accomplished either manually or mechanically by means of a chain-sprocket-reduction gear configuration attached to the central axis.
