Patent GB-2087682-A (GB)
Title: Distance measuring apparatus
IPC: G01F23/284
Filed: 1980-12-16
Abstract: Apparatus for measuring the distance from a point to a surface has a transducer (13) for launching periodic propagating energy, e.g. microwaves or acoustic waves, from the point towards the surface (12). The energy has either a predetermined continuous frequency band or a single frequency which is periodically swept through the band. The transducer is selected to be capable of both emitting and receiving the energy. The surface reflects energy back to the transducer which receives it and exhibits a frequency dependent transmission impedance. A detector (14) is coupled to the transducer and monitors the variation of transmission impedance with frequency to provide an output which is processed to indicate the measured distance, e.g. the level of liquid in a container. <IMAGE>

Title: Loudspeaker diaphragms
IPC: H04R7/12
Filed: 1981-08-25
Abstract: A loudspeaker diaphragm is made of an inner portion of one material, and an outer portion of a different material, the junction between the inner and outer portions being asymmetrical with respect to the axis of the cone. As illustrated in the drawings, in one embodiment of the invention, the junction 3 between the outer portion 1 and the inner portion 2 is located in a plane which is tilted with respect to a plane perpendicular to the axis of the cone.
