Patent GB-681854-A (GB)
Abstract: 681,854. Calculating-apparatus. BRUNSVIGA MASCHINENWERKE AKT. - GES. Oct. 13, 1949, No. 26345/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 28, 1950.] Class 106 (i). An arrangement, Fig. 1, for re-setting the item-entering levers 8 of calculating machines having axially movable totalizer-actuating gears 38, 39 set to their operative positions by pivoted levers 22, 23 movable by stepped setting surfaces 11 formed on the item-entering levers 8, comprises means for causing relative movement between the levers 22, 23 and the item-entering levers 8, in the plane of the latter, until the setting surfaces 11 no longer engage the pivoted levers 22, 23, the item-entering levers 8 then being returnable to their zero position by means such as springs 20. In Fig. 1, the pivoted levers 22, 23 are mounted for rotation about their longitudinal axes, one end pivot 24 being in a fixed frame 26 and the other end pivot 28 being in a vertically movable frame 30 pivoted at 29 to the machine casing and supported by a spring 33. Rotation of the item-entering levers 8 about a common axis 5 causes extensions 35 on the levers 22, 23 to be deflected outwards by engagement with the setting surfaces 11 on the levers 8, there being a corresponding inward movement of the other extensions 36, 37, on the levers 22, 23, to displace the gears 38, 39 to the necessary amount. The item-entering levers 8 are held in position by spring actuated pawls 15. When the frame 30 is depressed by a key 34 the extensions 35 are lowered below the setting surfaces 11 and the pawls 15 are deflected away from the item entering levers 8 by extensions 31 and the frame 30 acting on extensions 17 on the pawls 15. Each item-entering lever 8 is then returned to its zero position by a spring 20. In a modified construction, Fig. 3, depression of the key 51 causes the item entering levers 6<SP>1</SP> to be lowered below the extensions 351 on the levers 22<SP>1</SP>, 231 as well as their removal from the pawls 15<SP>1</SP> whose movement is limited by pins 53. The item-entering levers 6<SP>1</SP> are then free to be returned to their zero position by springs 201.

Title: Liquid crystal matrix display
IPC: G09G3/36
Filed: 1978-08-17
Abstract: A liquid crystal display comprises a liquid crystal cell having a thin layer of liquid crystal material contained between two glass plates which carry strip addressing electrodes arranged in an X, Y matrix of X times Y electrode intersections or elements. Electric signals are applied sequentially along both the X electrodes and the Y electrodes. The nematic-cholesteric liquid crystal material in the cell changes from an OFF state to an ON state with applied voltages above a threshold level Vc, changes from an ON to an OFF state when a zero voltage is applied, and tends to remain at its existing state when a voltage Vc is applied. In one example X electrodes receive +/- Vc voltages whilst Y electrodes receive in turn the pulse sequence of mVc followed by nVc scanned across the cell in the X direction with zero voltage at other times. Putting m=1, n=2, each element will receive zero volts, if that element is to be turned OFF, or 2Vc followed by 3Vc if that element is to be turned ON, with Vc applied at other times. In general the liquid crystal elements receive voltages of << Vc, Vc, (m + 1)Vc or (n + 1)Vc to show the desired pattern of information where n> 1>/=m>0. <IMAGE>

Patent GB-2026176-A (GB)
Title: Weighing method and apparatus
IPC: G01G9/00
Filed: 1979-06-08
Abstract: The mass of articles (13) is determined by feeding them from a feed station (10) to impact a cantilevered spring arm (18) at a weighing station (12) with a common velocity. A transducer (24) provides a signal representative of the momentum of the article on impact with a plate (20) on the arm (18). The signal may be used to provide an absolute or comparative resolution of mass. The mass may be related with a characteristic of the articles, such as radioactivity measured at radiation counters (28), to generate a mass-to- characteristic ratio. The articles can then be graded according to this ratio. The common velocity of the articles can be generated by free fall under gravity or by imparting a significant forward velocity from a conveyor. <IMAGE>

Title: Alcoholic stimulant beverages
IPC: C12G3/06
Filed: 1979-06-29
Abstract: This invention relates to improvements in alcoholic stimulant beverages based on known wine products. It is an object to provide beverages with the basic taste of known wine products, but greatly enhanced. The beverages have a considerably higher alcohol content and the extra taste of the spirits and aromas added. They are stronger tasting with a consistency in between that of the known wine products and liqueur. It is also an object to provide concentrated beverages which occupy a smaller volume than conventional wine products, and yet can be treated further to produce a taste corresponding to known wine products in a variety of available tastes, whereas wine alone is not suited to further dilution. By concentrating a wine product with alcohol for instance ethanol, brandy, rum and similar spirits, as well as taste ingredients like citrus or other fruit, besides a sweetening agent, a concentrated product is obtained occupying some half the volume of the equivalent amount of known wine products. Alternative components include aromatic essences, spices, herb extracts, fruit extracts and chemically flavoured ingredients. The invention provides concentrated alcoholic beverages capable of dilution with water or soda water to produce a range of available tastes for stimulation or enjoyment.

Patent GB-2041324-A (GB)
Title: Winding Wind Turbine Blades Correcting Mandrel Shape
IPC: F03D11/00
Filed: 1979-12-03
Abstract: The manufacture of large scale wind turbine blades is accomplished by winding composite fiber materials onto a mandrel to form the desired airfoil shape. The winding process requires that the fibers always maintain contact with the mandrel surface. If the surface is concave the fibers will form a bridge over the concave surface portion which produces a void. This invention avoids bridging by analysis of the blade design including the steps of defining a plurality of coordinate points on the surface of the blade prior to construction of the mandrel and winding thereof, and determining if a concavity will occur in the fiber winding plane passing through each coordinate point. If a concavity is located, the blade design coordinate point at the concavity is modified to eliminate the concavity and provide a continuous flat or convex surface in the fiber winding plane. The process can be automated by clerical or computing methods, and is repeated for each coordinate point until bridging is substantially eliminated.

Title: Apparatus for measuring the angular position of a shaft
IPC: G01B21/22
Filed: 1980-02-15
Abstract: An apparatus is disclosed, for measuring the angular position of a crank shaft of an i.c. engine at the occurrence of a rise in pressure in the fuel injection line to the engine, relative to a reference position of the shaft. The apparatus comprises a first sensor responsive to the reference position of the shaft (signal II) and a second sensor which, on the occurrence of the pressure rise, produces an output pulse and which produces a number of interference pulses in the periods between production of the output pulses (signal I). A comparator (4) having a threshold value B which is capable of being exceeded both by the required pulses and the interference pulses, and a recognition circuit (3, 6) which is adapted to recognise output pulses produced on the occurrence of the event, are arranged to control an evaluation circuit such as a counter (10). The evaluation circuit ascertains, e.g. by counting angular increment marker pulses (signal III), the angle through which the shaft rotates between the time when the threshold of the comparator (4) was last exceeded prior to triggering of the recognition circuit by the required event, and the time when the shaft reaches the reference position. <IMAGE>

Title: Externally-reset Tachycardia Control Pacer
IPC: A61N1/37
Filed: 1981-03-25
Abstract: There is disclosed an externally programmable pacer for controlling tachycardia (rapid beating) by interposing two stimulating pulses between beats, wherein placing a magnet over the patient's chest operates a reed switch of the device and results in the generation of two pulses, the time separation between which is an indication of the battery potential. After these two pulses are generated the device is inhibited, so that if the device is causing him discomfort the patient can temporarily disable it until the physician can program it off. In use, if tachycardia persists, the pacer repeatedly generates the two stimulating pulses during successive cycles of operation at times t, T which are "scanned" (i.e. advanced incrementally) from cycle to cycle over ranges A, B. The first cycle uses the times which were successful in terminating the previous tachycardia episode. Application of a magnet to the patient's chest (or programming of the device) resets the two time intervals to the starting values t, T programmed by the physician, however, so that the physician, after inducing tachycardia, can immediately verify these values by observing the patient's ECG waveform. <IMAGE>
