Title: Disc Brakes
IPC: F16D65/097
Filed: 1978-11-06
Abstract: The pads (4) of a disc brake assembly are held symmetrically relative to guide surfaces (14) of a carrier by springs (9) which clip over the backing plate (5) of each pad (4). The springs (9) each comprise two arms (10) which depend from a bridge portion (11) and resiliently grip the backing plate The edges (13) of the arms are bent out of the plane of the arms (10) and frictionally engage the surfaces (14). During limited forward movement of the pad (4) towards the disc the frictional engagement holds the edge of the springs (9) in position and the springs resiliently deform. When the brakes are released the springs (9) relax, thus retracting the pads (4) clear of the disc. Forward movement beyond a predetermined amount causes the springs (9) to slip on the carrier so that the amount of retraction remains substantially constant. The springs (9) include a portion (12) which biases the pads (4) into contact with the carrier guide surfaces (3).   <IMAGE>

Title: Torque-transmitting shaft coupling
IPC: F16D3/60
Filed: 1979-02-22
Abstract: Drive and driven members (1,2) are interconnected by intermediate element portions (3a, 3b) in a torsionally stiff manner through yielding joints (4,7), e.g. of tensile plate links, which accommodate axial, parallel and angular shaft offsets. An additional element (12) surrounds the intermediate element portion (3a): at one end these two elements are secured together rigidly and at the other end they have a frictional connection permitting relative rotary motion between a friction facing (11) and a rubbing surface (17) on a flange (15). The additional element has a substantially greater torsional stiffness than the intermediate element so that torsional vibrations occurring in the region of the critical speed of rotation are damped by the frictional connection. This can then prevent over- loading of the articulated connections by the forces arising with the vibrations. <IMAGE>

Title: Improvements Relating to Methods of Protecting Structural Members
IPC: E02D5/60
Filed: 1979-03-06
Abstract: Metal piles partially immersed in water require protection against corrosion, particularly over the zone subjected to alternate wetting and drying. To provide this, a jacket (3) is placed around the pile, leaving a space (5) to be filled with polyurethane foam. At the bottom of this space a barrier (16) of aggregate is provided through which water and air can permeate. Compressed air can be used to expel water from the space through the barrier, and then pre-frothed polyurethane foam is injected to fill the entire space, the barrier preventing its escape at the bottom. The foam can itself be used to expel the water. Similar protection can be applied to concrete or wooden piles. <IMAGE>

Title: Mining machine haulage
IPC: E21C29/02
Filed: 1979-03-21
Abstract: A mining machine haulage involves a rail 11 along which the body of the mining machine is movable, and support means 10 for the body engaging the rail so that the body is carried by the rail, there is provided driving means for the body including a rack 8 along which the body is movable and a drivable endless chain 1 on the body meshing with the rack. A serious disadvantage of this arrangement is that on clogging of the inter-tooth spaces of the rack with coal dust, the driving means lift the body which in turn lifts the support means from the rail so that the body is supported by the endless chain which becomes damaged and adversely affects the drive. This disadvantage is now overcome by adjustably mounting the support means as by cranked axles 12 for movement back into contact with the rail. Advantageously, with driving means including guide means 7 on the body frictionally engaging the chain to maintain a length of the chain in mesh with the rack, and with the rail disposed alongside the rack, the support means 10 for the body are adjustably mounted on the guide means for the chain. <IMAGE>
