Title: Fishing rod with bite warning signal - has float on tube over line hitting buoy to cause noise
IPC: A01K93/02
Filed: 1975-01-02
Abstract: A light rigid tube (1) of small diameter compared to its length passes through a buoy (2) having a conical shape, with the point of the cone pointing upwards. A spherical float (5) is fitted to the upper part of the tube. To the lower part is attached a traditional float (7) drilled to take the tube. The line (9) passes through the tube to which it is secured by a locking device n12) and carries a hook (10). When the fish bites the hook it pulls the line which causes the spherical float to move downwards. In so doing it strikes the bouy, which slides on the tube and remains on the surface, causing an audible signal, so warning the fisherman of a bite.

Title: Vehicle disc brake shoe - has layer of material on reverse face to damp out oscillations
IPC: F16D65/092
Filed: 1975-03-21
Abstract: The shoe has the lining attached to one face, while on the other face a layer is attached of material allowing some relative movement, so that any oscillations occurring when the brake is applied are damped out. The layer can be secured to the shoe by resilient binder material, or it can be in the form of a thin metal plate riveted to the shoe, the rivets passing through spring washers between layer and shoe. Alternatively it can consist of a metal spring plate with tongues bent over to secure it to the shoe. As a further alternative, it can be in the form of a mat of aligned metal fibres joined by a binder material sufficiently rigid to make it self-supporting, but allowing oscillation of the fibres in relation to each other, and of the mat in relation to the shoe.

Title: Vehicle shock absorber rubber washer - has initially low resistance to axial or pivotal loads progressively increasing
IPC: F16F9/54
Filed: 1975-05-06
Abstract: A vehicle shock absorber easily deflects under both axial and pivotal loads initially, but the mounting stiffens up in both cases as the loads are increased. Specially shaped rubber washers (5,6) are used, retained on the shaft (9) between cup washers (3,4) on either side of the frame (7). Each washer has a substantial base (1) of large radius and then extends into a thinner lip (2) which is turned out wards away from the shaft. In use, the bases are in contact with the frame and the lips in contact with the cup washers, so that initial small axial or pivotal loads easily deform the lips first and then encounter the greater stiffness of the thick bases.

Title: Detection of neutrons - using superconducting-normal state transition by radiation emitted when neutron is absorbed, giving good spatial resolution
IPC: G01T3/08
Filed: 1977-01-17
Abstract: Method of detecting neutrons makes use of the phenomenon of transition of grains or homogeneous films of a superconductive material towards the normal state under the effect of a photor or a charged particle emitted when the neutron is absorbed by a material. The appts. incorporates a neutron receptor comprising a medium which absorbs neutrons and emits electromagnetic radiation or a charged particle, and grains or a film of superconducting material. Specifically, the receptor includes a cryostat to maintain the superconducting material below the critical temp., and a means of creating a magnetic field of specific value to maintain the material in the superconducting state in the absence of radiation. A circuit measures a quantity or a change in a quantity associated with the state of the material to detect the transition of the material from the superconducting state towards the normal state, e.g. change in resistivity, magnetic permeability or magnetic flux. Method is efficient and gives good spatial resolution.
