Abstract: A hydraulic brake master cylinder (12) for a vehicle braking system defines a first smaller fluid path (70, 50, 56, 34, 42, 44) and a second larger fluid path (72, 50, 56, 34, 44, 42) for connecting a working chamber (32) with a fluid reservoir at ambient pressure when the cylinder piston (28) is retracted and the brakes are not applied. A pressure relief valve (76) normally closes the second fluid path but is arranged to open when subject to a pressure differential at or above a threshold value. The first fluid path allows a restricted return flow of fluid to the reservoir should a standard knock-back event occur. If a larger knock-back event occurs causing a fluid pressure spike at or above the threshold value, the pressure relief valve (76) opens to allow a higher volume return flow through the second fluid path to dissipate the pressure quickly.

Abstract: In one aspect, the present disclosure provides a method including rotating a rotatable surface with an object positioned thereon to a plurality of angular positions. The method also includes capturing, via an x-ray microtomography device at each of the plurality of angular positions, a tomograph of the object. The method also includes summing each tomograph of the object to create a three-dimensional image of the object. The method also includes using an additive manufacturing machine to create a three-dimensional replica of the object using the three-dimensional image of the object.

Abstract: A device for processing fish, the device comprising: an open channel through which a fish can pass; a fish processing means associated with the channel; a vertical guide plate pivotally mounted on each side of the channel, having a firing position and a retracted position; a mechanism for moving the fish processing means from a (“firing position”) to a position which allows passage of the fish through the channel after processing (“retracted position”); a mechanism for pivoting each guide plate between the firing and retracted positions (“guide plate pivot mechanism”); a trigger that when contacted by the head of the fish activates the fish processing means; and a mechanism for resetting the device after the processing of a fish, wherein the resetting mechanism is in communication with the trigger and wherein actuation of the mechanism by the trigger facilitates: activation of the fish processing means; movement of the fish processing means and guide plates from their respective firing positions to their resp

Abstract: A device for stunning fish comprising: an elongate member comprising an open channel through which a fish can pass; a pneumatically operated gun pivotally mounted in said channel, said gun comprising an impact cylinder and piston, wherein said piston is connected to a cylinder striker which is retractably extendable from a sleeve on said cylinder, and wherein said gun can pivot between a lowered firing position where said striker can stun said fish at a set point in a channel and a raised position where said fish can pass beneath said gun; a vertical guide plate pivotally mounted on the internal surface of each wall of said channel and having extended (outward) and retaracted (inward) positions, wherein the end of a guide plate distal the pivotal mounting is at or near said set point and the pivotal mounting is between said set point and the channel entry; a mechanism for pivoting said gun between said lowed and raised positions; a mechanism for pivoting each said guide plate between said extended and retract

Abstract: Stunning device (1) for small animals or fish of 2 kg to 7 kg weight comprises pneumatically powered piston assembly (2) which includes an extendible piston. Support (3) for piston assembly (2) includes base member (4) and multi-component trigger (22, 23, 24, 26). Piston assembly (2) is positioned to define a space between base member (4) and head plate (21) for receiving the head (27) of the animal. When the piston is activated by head (27) contacting plate (22), it extends and strikes head (27) just behind and/or between the eyes with sufficient force to kill the animal with a shock to the brain, but without affecting the external appearance of the animal or fish. The piston extends only once and then retracts, and trigger (22, 23, 24, 26) is reset by removing head (27) from device (1).

Abstract: An operating lever mechanism for a master cylinder which includes a mounting bracket (12) and a lever (23) mounted on the bracket trough a pivot pin (22). The lever is connected to a master cylinder actuating rod (25) and the pivot pin (22) is adjustably mounted on the bracket in slots (27) so that by turning an adjuster wheel (31) the pin (22) is moved in the slots (27) to vary the distance between the pivot axis of the lever and the connection of the lever with the master cylinder actuating rod (25) to adust the operating lever ratio of the mechanism as desired.

Abstract: A motor cycle disc brake has a disc secured by an outer peripheral portion to the rim of a wheel which is rotatable about an axle held by a pair of fork legs. A brake caliper is secured to a fork leg and straddles the inner periphery of the disc. The disc is secured to the wheel rim by bolts which allow the disc some axial play relative to the rim to compensate for any run out of the rim. The caliper is fixed to the fork leg by a pair of securing members one of which engages in a recess in a lug on the fork leg so that the caliper can be released quickly from the fork leg.

Abstract: A brake disc assembly with fasteners for securing the disc to a wheel, together with spacers associated with the fasteners for allowing the disc limited axial play relative to the wheel, there being a holder on the disc having surfaces between which the spacers are gripped.

Abstract: A brake disc comprises an inner mounting member and outer annular braking member and a driving connection between the two members. The braking member has the usual flat annular braking surfaces. The driving connection comprises a square shaped drive dog which engages in corresponding notches in the outer periphery of the mounting member and the inner periphery of the braking member. The notches have flat driving faces in engagement with corresponding flat faces on the drive dog. Axial location is by stop flanges secured together through an aperture in the drive dog. The axial length of the dog is greater than the thickness of the disc members so the flanges, in engagement with the axial end faces, allow some axial movement. A crinkle washer controls the relative axial positions. There are a plurality of drive dogs spaced equally around the disc.

Abstract: The invention relates to motor vehicle reservoir and master cylinder assemblies in which a hydraulic master cylinder can be mounted onto the vehicle in a large number of attitudes with respect to the vehicle without the limitation of maintaining the reservoir in an upright position. The reservoir is mounted directly onto the master cylinder by an adjustable means so that the attitude of the reservoir can be readily selectively adjusted relative to the master cylinder to ensure that the reservoir is substantially upright.
