Patent GB-2208022-A (GB)
Title: Voice interval detection system
Inventor: MUROI TETSUYA
IPC: G10L15/00
Filed: 1988-09-23
Abstract: A voice or sound recognition system including a microphone for converting a voice into an electrical voice signal, a frequency analyzer for generating a voice pattern in the form of a time-frequency distribution, and a matching unit for matching the voice pattern with registered voice patterns. A voice pattern sometimes contains a bass bar section starting from the beginning of the voice pattern over a time period. In one form of the present invention, the bass bar section is detected and/or eliminated before processing the voice pattern for the purpose of registration or matching. The voice level is sometimes too strong or too weak for appropriate processing. In another form of the present invention, a voice recognition system including a voice input cancelling function is provided. In addition, a system for detecting a voice interval for use in voice data processing, including a device for determining a start point of the voice interval is provided.

Patent GB-2228823-A (GB)
Title: Thermo-electric generators and heat pumps
Inventor: JONES GEORGE LAWRENCE
IPC: H01L35/26
Filed: 1988-11-16
Abstract: A thermo-couple comprises matching p-type and n-type thermo-elements designed to have a Seebeck co-efficient that varies from a maximum at the hot junction to a low or zero value at the cold junction in the case of a generator, and from a maximum at the cold junction to a low or zero value at the hot junction in the case of a pump. The variation in Seebeck co-efficient is obtained by altering the amount of dopant along the length of the element. The amount of dopant is a prescribed function of the temperature of the element. The elements can be prepared from powders by separately metering the basic material and dopant, mixing, pressing and sintering.

Title: Moulding a refractory nozzle for the casting of molten metal
Inventor: SUGIURA SADANOBU
IPC: B28B3/00
Filed: 1991-03-18
Abstract: The refractory nozzle is formed from a thin refractory sheet (1), which is prepared from a material slurry by a device such as a doctor blade, or by injection or extrusion moulding. The sheet is put on a mandrel (2) e.g. by winding, of the shape of a nozzle body, and isostatically pressed through an elastic mold (3) set on the body. The sheet (1) may be shaped like a belt preferably for winding them on the core. Grain segregation does not occur in the method, as in the prior art slip casting, or isostatic pressing of granules, thus the provided nozzle has a uniform distribution of materials and density and a lamination structure which improves resistivity against heat generated by the molten metal in actual use. The refractory sheet may be of a slurry of various specified materials, such as ceramics, metallic silicon, graphite, or of pitch or of resin powder as a carbon source. <IMAGE>

Title: Variable crimp height device.
Inventor: RAYNOR TERENCE ROBERT
IPC: H01R43/048
Filed: 1993-06-01
Abstract: An Infinitely Variable Crimp Height Device that can achieve variation of Crimp Height to obtain the optimum Crimp Height for a given wire size within the Maximum and Minimum range of the wire sizes of any specific electrical terminal. The selected position is achieved by the rotation of a Wire Disc Fig 4 which can be locked in the chosen position by a locking screw. The wire disc Fig 4 has a helical undersurface which contacts the helical upper surface of a fixed helix Fig 5 located below the wire disc thus providing variation in the crimp height by increasing or decreasing the effective length of the applicator ram Fig 7. The Device is capable of transmitting the thrust required to achieve the crimp form from a power press and this thrust is balanced either side of the ram centreline. It can be fitted to conventional Mini-Applicator Tools in place of the present methods currently used. <IMAGE>
