Title: A microphone adaptor for a respirator
Inventor: DAVIES JOHN
IPC: A62B18/08
Filed: 2001-01-29
Granted: 2005-02-02
Abstract: The invention deals with the problem that, when the user of a radio headset having a boom microphone wears a respirator, he can no longer effectively use the microphone. The invention solves the problem by the simple expedient of a sound tube (14B) which leads from a first end (14a) located at a position where speech can be received from the respirator, to a second end (14c) which makes a push fit over the boom enabling clear speech to be received by the microphone (15). Advantageously the sound tube has a microphone box (14c) for receiving the end of the boom and for directing the sound inwardly through a lateral hole in the boom to a microphone sensor inside.

Title: Block redundancy for memory array
IPC: G11C29/00
Filed: 1980-05-22
Granted: 1984-03-07
Abstract: Block redundancy is utilized to improve yield and lower die cost for an electrically programmable read only memory (EPROM). The EPROM is organized 8Kx8 with four primary memory blocks on each side of a central row decoder. Each block includes an array of memory cells, column select, column decode, sense amp, data buffer and other overhead circuitry. One block of redundant circuitry is also provided for each set of four blocks and includes a redundant memory matrix, a redundant column decoder, a redundant column select, a redundant sense amp and a redundant data buffer. Incorporated within each primary memory block is a multiplex logic circuit which is independently programmable to selectively disconnect the associated primary memory block and substitute the redundant memory block, including the redundant column decoder, column select, sense amp and data buffer. Each multiplex logic circuit includes a polysilicon fuse which is permanently programmable from a closed to an open circuit condition by applying a high voltage to the external data bit terminal which corresponds with the defective memory block cells. According to this arrangement, for each group of blocks, one out of four primary memory arrays including the associated column select, column decoder, sense amp and data buffer, may be replaced during wafer testing and after encapsulation.

Title: Gelatin prepn. from animal waste - by alkali washing, reducing to a paste, neutralising, hydrolysing the resulting collagen and gelling esp. continuously
IPC: C09H/
Filed: 1978-01-05
Granted: 1985-07-12
Abstract: A process for prepf. collagen for gelatin mfr. from animal waste comprises treating the waste constituted by skin, sinews and tendons by the following successive operations. The material is first washed and defatted in soda soln. to expand the pores and facilitate the removal of blood and fat. Then the material is reduced to a paste by physical means. The paste is then neutralised, washed with cold water and pressed to remove any water leaving a cake of pure collagen. The collagen, opt. after drying and storing is hydrolysed to form a light density broth which gelled at low temp. and dried. A particular appts. feeds the broth near its gelling paint to a stainless steel band conveyor which circulates in an area kept at 0-10 degrees C esp. about 5 degrees C. From there, the film of gelatine passes to a second area via a series of belt conveyors passing from top to bottom; this area is maintained at 10-30 degrees C with a blower providing a feed of fresh air. The process which uses select waste materials enables a much shorter process time (1 -1 1/2 days, compared with 6-8 weeks, a continuous process, and much pleasanter working conditions.

Title: fuel economiser for automobile engine carburettor - has piston held in neutral position by opposed springs and movable to control air flow in response to inlet manifold vacuum (BR 28.8.79)
IPC: F02M/
Filed: 1978-01-25
Granted: 1985-07-12
Abstract: A carburettor which economises on fuel has a needle valve adjuster with a hollow cylindrical head. A piston slides inside the head and is normally held in the mid-position by two springs. When the engine is idling the depression in the inlet manifold forces the piston towards the pointed end of the needle and seals the central bore. As the engine speed increases and the inlet depression decreases, the springs restore the piston to the central position and allow extra air to flow to the carburettor and provide a lower fuel to air ratio.
