Abstract: A closure cap is provided for an opening in a vessel. Inner and outer seatings extend around the opening. The closure cap has a body with attachment means to enable the cap to be releasably secured in the opening, and the body also has an inner seal for engaging the inner seating and an outer seal for engaging the outer seating. The cap is characterized by the fact that at least one of those seals comprises an outwardly directed flange of a flexible and resilient plastics material supported at its inner edge and yielding resiliently when in use. The flange is urged towards the associated seating due, at least in part, to the innate resilience of the material from which it is made.

Abstract: In an hydraulically operated disc brake one of a pair of guide pegs for a caliper works in an inner elongated bore in a resilient bush with same play in a transverse direction the bush being located in a bore of one of a pair of guide members, the play between said peg and bush accommodating changes in the circumferential spacing of the guide members or guide pegs due to distortion of a stationary, drag-taking part of the brake.

Abstract: In a pressure reducer valve assembly for a vehicle braking system a valve member co-operates with a valve seat of which opposite sides communicate with an inlet connected to a master cylinder and an outlet for connection to a brake, a pressure responsive member controls the position of the valve member in opposition to a spring urging the valve member away from its seat and the position of an abutment member for the spring is controlled in response to a difference in the pressures in two pressure spaces of a master cylinder which supply independent braking circuits.

Abstract: A pressure control assembly comprises a control valve set for controlling communication between an inlet and an outlet, a control spring acting in a sense to resist closure of the valve set and a device for varying the control force of the control spring acting on the valve set. The device for varying the control force may comprise a differential pressure responsive member which moves in response to a differential pressure to move an abutment engaging the spring between normal and actuated positions to compress or expand the spring and thus vary its force.

Abstract: The present specification describes and claims a friction pad assembly for use in a sliding caliper disc brake and a sliding caliper disc brake incorporating such an assembly. The friction pad assembly comprises a backing plate, a pad of friction material secured to the backing plate, and a leaf spring, a central clip portion and two oppositely directed arms forming said leaf spring, the leaf spring being attached to the backing plate by means of said central clip portion. When the assembly is incorporated in a sliding caliper disc brake which comprises a torque member and a caliper member, the leaf spring engages the caliper member both pressing the friction pad assembly down onto guides in the torque member and biassing the torque member and caliper member apart to take up any clearance. Thus the possibility of the assembly rattling in the brake and the torque member and caliper member rattling together, is reduced.

Abstract: A sliding caliper disc brake has a caliper member slidably mounted on a fixed torque-taking member and carrying an actuator which urges a friction pad onto one side of a rotating disc whereupon the caliper member slides on the torque member and applies an opposite pad to the other side of the disc. Both pads are carried by the torque member so that circumferential drag forces experienced by the pads when they are clamped against the rotating disc are transferred directly to the torque member. The sliding connection is provided by a pin secured to one of the members and slidable in a bore in the other of the members.

Abstract: In the shaping of ductile metal sheet, especially superplastic alloy sheet, by the application of pressure differentials, the peripherally clamped sheet is first urged, by pressure differential in one direction, against a female molding surface to form a partially shaped bubblelike preform and then a male mold is advanced towards the sheet from the other side and a reverse pressure differential is applied to cause the pre-form to conform to the shape of that mold. The active area forming the pre-form may be restricted by an apertured plate adjacent the clamping plane, matching the overall outline of the body, and a plate the other side matching closely the profile of the body may confine the action of the reverse pressure only to that part of the sheet that engages the progressively increasing part of the male mold that extends through the clamping plane so that the sheet locks progressively onto the sides of the male mold to obtain an approximately uniform wall thickness in the finished body.

Abstract: A floatable toy, for example a boat, has two hulls and a reservoir or container for water mounted between the hulls. A discharge outlet is connected to the reservoir at or near its bottom and is directed rearwardly of the toy, so that water is discharged from the reservoir through the outlet to provide a reaction with the water on which the toy floats and drive the toy. The reservoir is spaced from the water on which the toy floats even when it is filled with water.

Abstract: A coating apparatus for manufacturing of solid particles with digestive tracts-soluble film by rolling water-containing solid particles at high speed, adding a coating liquid and drying them simultaneously. Particles are disposed in a generally annular volume and supported on a generally rotary disk which is closely confined within a fixed cylinder and closely spaced from an inner fixed cylinder; said cylinder forming said annular volume. Partition means adjustably spaced from said plate, divide said volume into separate coating, water feed and drying chambers. The partitions form a sealing relationship with the particles.

Abstract: An engine for driving an automotive vehicle has a plurality of turbine rotors mounted on the main drive shaft. Compressed air is supplied to the rotors in succession from a distributing valve which is supplied with compressed air from a main air tank, and compressed air at reduced pressure from the delivery side of each rotor is supplied to a manifold which also supplies the main air tank through a second stage compressor.

Abstract: A storage assembly in which a row of storage units, such as racks, are movable between fixed limits along the length of the row in either of two opposite directions so that a gangway can be provided between the sides of any two adjacent units, and in which each storage unit is provided with a set of reversible electric motors adapted to drive individual independently rotatable drive wheels to move that storage unit, and a set of switches is provided along each side of each storage unit so as to be operated by means at the side of an adjacent storage unit, each switch in each set being associated with a respective reversible motor in the vicinity of the switch so as to control operation of that motor independently of the others and to cut-off the supply of electricity to the motor when it is operated. Thus each motor will continue to operate to move the part of the unit by which it is carried until that part reaches a datum position defined by the side of an adjacent storage unit.

Abstract: In a disc brake of the sliding yoke reaction type a friction pad assembly adapted to be applied directly to a rotatable disc by actuating means is provided at opposite ends with lugs which engage over spaced arms in a stationary member so that, when the brake is applied, the drag on the pad assembly is taken by the arm at the end of the brake with which any point on the disc first comes into alignment for a given direction of disc rotation.

Abstract: Almost all of the powder materials, after having been calcined in a calcining furnace, are treated by the high temperature kiln exhaust without being directly fed into a rotary kiln, so that the materials may pass through at least two calcining zones in series so that they are calcined perfectly and uniformly before they are fed into the kiln, thereby contributing to make compact a rotary kiln in size and to improve overall thermal efficiency of the calcining and burning (sintering) apparatus.

Abstract: In scaffolding a cross member is connected to an upright member by means of a dependent spigot which engages in a socket on the upright, and is secured to the upright by jamming the spigot in the socket by means of a retaining member carried by the cross member which is movable relative to the spigot by rotation of an associated cam.

Abstract: An inlet line connected to the inlet of a hydraulic pump includes a jet pump having a Venturi nozzle though which the aspired liquid is passed, and into which a coaxial jet of liquid under higher pressure is introduced to raise, by jet-pump action, the pressure of the liquid at the pump inlet.

Abstract: A support is forced to be extended between a longitudinal member of a hull block clamped between a movable jaw and a fixed jaw on the one hand and another longitudinal member located adjacent to the first mentioned longitudinal member so that the load exerted to the clamping device when the hull block is lifted as well as the reaction force exerted to the support may force the movable jaw against the longitudinal member to firmly clamp it between the movable and fixed jaws. The longitudinal member is so firmly clamped between the movable and fixed jaws that it is not released even when the hull block is lifted in the vertical position.

Abstract: A rotatable braking member, for example a disc or a drum, for a vehicle brake is provided with a separate plurality of spaced cooling fins having a co-efficient of thermal conductivity higher than that of the braking member to dissipate heat to a flowable working medium within passages between adjacent fins, and at least some of the passages are substantially uninterrupted circumferentially with respect to the direction of rotation of the braking member.

Abstract: The present invention discloses a device for gripping and lifting large-sized T-shaped structural members (to be referred to as the "T structural member" for brevity in this specification) each consisting of a face plate and a web plate. The T structural member gripping and lifting device comprises a beam adapted to be suspended from a crane or the like, a plurality of trolleys movably mounted on the beam and remotely controlled so as to adjust the spacing therebetween, a gripping unit suspended from each trolley and remotely controllable so as to grip or release the face plate of a T structural member, and a remote control unit for controlling the trolleys and the gripping units whereby the T structural member may be automatically gripped, lifted and released. Handling efficiency may be considerably increased to such an extent hitherto unattainable by any conventional devices, and the safeguarded operations may be ensured.

Abstract: A sliding caliper disc brake has a caliper member which applies friction elements to opposite sides of a rotatable disc and which is slidably mounted on a fixed torque-taking member by a single pin disposed at one side of the caliper. The other side of the caliper is urged into sliding engagement with the torque member by a spring arranged between the caliper and a projection on the torque member. The caliper carries a lug which is normally spaced from the projection but is engageable with the projection to limit outward pivoting of the caliper about the pin in the event of failure of the spring. The caliper lug may engage the spring so as to slide the spring on the projection upon sliding of the caliper so as to maintain spring orientation as the friction elements wear.
