Patent GB-2151113-A (GB)
Title: Sound monitoring apparatus
Inventor: KATZ HART V
IPC: A61B7/04
Filed: 1984-10-19
Abstract: Sound monitoring apparatus is described which provides a slowed down version of the original sound, e.g. a heart beat, without changing the quality of the perceived sound. The amount by which the sound is slowed down can be varied by the user. The original sound is converted to an analog electrical signal, digitised and electronically processed in a microprocessor-based circuit such that digital data corresponding to cycles of the analog signal are stored in a random access memory. The microprocessor reads out the digital data a predetermined number of times corresponding to a number of sound cycles according to the rate set by the listener. The digital data is reconstituted into sound which is composed of replicated sets of cycles of the original sound. The repetition rate of a heart-beat in the output sound is a fraction of the repetition of the heart-beat in the original sound but the sound quality appears the same to the listener as the pitch is invariant. <IMAGE>

Filed: 1986-10-14
Abstract: A workbench comprising a rectangular framework formed from a plurality of first mutually parallel spaced apart elongate members 1 and a plurality of second mutually parallel spaced apart elongate members 2 arranged perpendicular to the first members. The first and second members are secured together such that, on one side of the frame, edges 3 of the first members project beyond the second members to define a plane spaced from adjacent edges of the second members, and such that, on the other side of the frame, edges 4 of the second members project beyond the first members to define a plane spaced from adjacent edges of the first members. The workbench may be supported in any suitable way, for example on a table. A large sheet of material can be supported on the uppermost side of the workbench. If the sheet is to be cut with an electric saw, the sheet is positioned with the uppermost elongate members parallel to the intended line of cut. It is then simply necessary to ensure that the saw blade position does not coincide with any of the uppermost elongate members. The blade passes over the lowermost elongate members without risk of damage. After the sheet has been cut, the two resultant sheets are both firmly supported. The workbench can be placed with the side uppermost which best suits the shape of the sheet to be cut and the direction of the cut. The bench may be provided with tool support boards 6,7,8,9, vices 15 or 17 and further work supports 5. <IMAGE>

Title: Underwater explosive device
Inventor: JONE TIMOTHY MEALLE
IPC: F42B3/00
Filed: 1987-09-21
Abstract: A material (7) which will react with water to produce an explosion is encapsulated in a rigid plastics housing (1). The housing is sealed by a lid (3) so that water cannot normally enter the housing. However, a central region (5) of the lid is of reduced thickness so that, if the device is dropped into deep water, this weakened portion of the lid will give way due to the water pressure at a predetermined depth, and an underwater explosion will result. The noise caused by the explosion can be of sufficient magnitude to confuse sonar detection equipment in the vicinity. Many of the capsules can be deployed in succession in order to produce virtually continuous noise. The material may be a mixture of potassium chlorate and potassium metal. <IMAGE>
