Title: Contact sensor for area surveillance - uses sensor wire connected to piezoelectric or electromagnetic transducer
IPC: F42C11/00
Filed: 1974-01-10
Abstract: The sensor comprises a thin wire (10) vertically supported on an oscillatory membrane (15), which closes a box (16) in which a piezoelectric element (17) is sealed in epoxy resin (18). When the wire is disturbed its oscillatory movement is transmitted by the membrane to the piezoelectric element which transmits corresponding electric signals along connection lines (14) to a receiver. A mechanical contact may replace the element. Alternatively, the wire may form part of an oscillator whose oscillation frequency is varied by contact of the wire with an external object, this being effected by a change in inductance or capacitance of which the wire forms part. The piezoelectric element and oscillator may be combined in a sensor to provide sensitivity to both noise and metal objects. The sensor is used for recognising certain characteristics of vehicles, e.g. tanks.

Title: Automatic alignment mechanism for bicycle chain - has notch in control lever wider than end of control spring
IPC: B62M25/04
Filed: 1974-10-04
Abstract: The mechanism automatically aligns the chain with the various sprockets on the rear wheel has a control lever pivoting on a fixed axis round which a sleeve can turn freely. Retaining and adjustable axial pressure devices act against one end of the sleeve. The end of a spring (15) engaging in the lever (11) fits in a notch in the latter appreciably wider than it, so that one side of the notch moves the spring end in the angular direction when the lever is moved to shift the chain to a sprocket of larger diameter, thus pulling hard on the cable (10) in order to overcome the thrust of the change-speed spring. Once shifting is complete, it is merely necessary to release the lever, whereupon the latter spring pulls it back until the other side of the notch strikes the spring end.
