Patent GB-2082820-A (GB)
Title: Devices, Systems and Methods for Converting Speech into Corresponding Written Form
IPC: G10L15/00
Filed: 1981-08-20
Abstract: In a system for converting speech into corresponding written words, the spoken word is converted directly into the written word by the use of an automatic speech recognition device or "translator" (30), which translates the spoken word into corresponding coded signals, and a word processing system including a dictation terminal (10). To compensate for the limited vocabulary and other shortcomings of the translator (30), special control means are provided for allowing the dictator to verbally spell out each word or expression which the translator is incapable of translating; alternatively such words may be entered from a keyboard. In this mode of operation, the system automatically assembles the letters together to form words, and assembles the words so formed with other words to form sentences. The spoken words and letters appear an the video display screen of the word processor dictation terminal (10). The dictator views the text, makes any necessary corrections, and either stores the text codes in an electrical storage device (32) for later transmission to a printer, or directly transmits the text codes to a printer (34, 36, 38) which prints the text as a relatively high speed. The spoken words may be recorded on magnetic tape which is then read at a speed suitable for the translator (30). <IMAGE>
Patent GB-2087617-A (GB)
Title: Continous speech recognition method and apparatus
IPC: G10L15/10
Filed: 1981-11-11
Abstract: This speech signal recognition system compares the two-dimensionals pattern (time sequence of feature vectors) of an unknown signal to prestored standard references patterns for recognition, thus forming a corresponding two-dimensional comparison pattern of points of elemental Hamming distance differences. The sum of the pattern point distances is the similarity measure. To improve accuracy, partial patterns are selected (or "masked") and tested sequentially, and the point values weighted relative to their location within the mask. The mask may be rectangular or oblique.

Patent GB-2104912-A (GB)
Title: Detergent composition
Inventor: DAVIES JAMES FRANCIS
IPC: C11D3/10
Filed: 1982-06-16
Abstract: Fabric, particularly soiled fabrics containing calcium carbonate crystal growth poisons, may be washed in hard water to which has been added a detergent active material and an alkali metal carbonate if a secondary detergency builder is added after a defined critical state of the system is reached. The secondary builder may be a precipitating, sequestering or ion exchange builder, and is added in such an amount which would be insufficient, in the absence of the carbonate, to reduce the free calcium ion concentration to less than 10-5 molar. The delayed addition can be achieved by separate dosing, coating the secondary builder, dosing the composition in the form of a two-compartment sachet or forming the secondary builder material in situ. The composition may include a material, such as calcite, to promote the occurrance of the critical state.

Title: Eye-beautifying mask to be used while sleeping
Inventor: MOLNAR DANIEL
IPC: A61N1/32
Filed: 1984-04-27
Abstract: A mask with the aid of which wrinkles, oedemae and pouches on the most sensitive part of the face, i.e. around the eyes can be prevented or reduced. An electronic circuit (Figure 2) is built into the sleeping mask. It has two electrodes (1) fittable to the muscles around the eyes. The circuit generates spikes or sharply peaked pulses which tend to accelerate the blood circulation and increase metabolism, as a result of which the region of the skin around the eyes is smoothed and becomes more elastic. The sleeping mask according to the invention enables treatment to be performed at home; the mask can be used at home while sleeping, and under the influence of the pulses sleep becomes deeper and quieter. The circuit includes a multivibrator with an inductive load L1 and powered by a rechargeable battery 4. <IMAGE>

Title: Self-adjusting clutch control mechanism
Inventor: ROBINSON MICHAEL
IPC: F16C1/22
Filed: 1984-12-08
Abstract: A flexible clutch control cable associated with a conduit anchoring component (6) which is normally open to permit the position of the conduit (2) relative to an abutment or fixture to adjust itself automatically to compensate for clutch wear, is provided with a leaf spring (16) which bears against the core (1) of the cable to cause entrainment of the anchoring component into conduit-anchoring position by the core (1) during an initial part of its stroke. The leaf spring (16) is mounted cantilever fashion to permit axial movement of its free end under pressure exerted on the spring by the core, and adjacent the spring there is a guide passage (19) which limits the extent to which the spring can be flexed by exerting abaxial deflecting force on the part of the core projecting from the conduit anchoring component. <IMAGE>
