Abstract: 1345771 Keyboards COLORADO INSTRUMENTS Inc 19 April 1971 [20 Feb 1970] 20271/71 Heading G4H [Also in Divisions G1 and H1] A variable capacitor functioning as a capacitive switch in an electrical signal device, comprises a fixed conductive plate 13, a dielectric layer 14 and a resilient domed conductive plate 23 and means such as key 31 and spring 33 for deforming the domed plate to achieve by a snap action a change in the separation of the two plates. As shown, plate 13 as well as conductor 19 are formed by etching techniques on copper coatings on both sides of insulating substrate 11 and lead 21 connects plate 13 to conductor 19. Domed plate 23 has a lead 25. In a modification (Fig. 2, not shown), an electret is located between the fixed plate and domed plate. Further, a block of resilient material may be used instead of spring 33. The signal generated by actuation of a single key may be detected by a circuit wherein a resistor is connected at one end to a voltage source and at the other end through the capacitive switch to earth, and the junction between resistor and capacitive switch is connected to the input of a Schmitt trigger circuit (Fig. 3, not shown). The fixed electrode may be divided into two isolated portions (Fig. 5, not shown) and in a keyboard assembly respective portions are electrically interconnected as elements of an x-y matrix (Fig. 6). As shown, each x line and y line is connected through a signal conditioner comprising a Schmitt trigger circuit and pulse stretcher to an x and y encoder respectively, whereby the two signals generated on depression of a key may be encoded for direct application to digital data processing systems. To provide a gate signal for each key depression (Fig. 7, not shown), all x and all y line signals are applied as inputs to a respective OR gate, and the outputs thereof to an AND gate, so that both an x and a y signal must be generated simultaneously for the AND gate generates an output signal for application to a multivibrator. Further, to detect simultaneous actuation of two keys, each x and y line is connected through a resistor to a respective common line and each common line is connected through a respective resistor to a respective voltage source (Fig. 8, not shown). The two common lines are connected one to each of two Schmitt triggers whose outputs are connected to an OR gate. The output of the OR gate is connected to an error register. The Schmitt triggers are actuated if more than one x or y signal is generated simultaneously but not if only one x or y signal is generated. The fixed electrode may be divided into three (Fig. 9) or more portions so as to generate a corresponding number of signals for each key depression.

Filed: 1949-08-09
Abstract: 692,551. Filling bottles. DETREZ, R. Aug. 9, 1949 [Aug. 9, 1948], No. 20662/49. Class 125(ii) A machine for filling bottles and like containers, wherein the filling nozzles have a member closing the neck of the bottle during filling, a pipe or channel for feeding the liquid into the bottle and a tube for connecting the inside of the bottle with a vacuum chamber or a compressed gas supply, comprises means for applying a plurality of different pressures for urging the closing member and the bottle neck against each other and opening the liquid admission pipe against the action of springs. As shown in Fig. 1, a bottle is filled from a reservoir through a filling nozzle having a tube 24 connected to a vacuum chamber and a pipe 25 leading to a reservoir so arranged that, when the neck of the bottle engages a member 28, the bottle is evacuated through tube 24 and the pipe is pushed away from a valve closing member 26 to allow liquid to enter. The bottle is supported by a carrier 23 which is raised and lowered, through a rod 22, by a piston 20 to either side of which fluid can be fed by pipes 19, 21, the fluid being supplied from high and low pressure supply pipes 7, 8 under control of a rotor 2 having ports 30, 31 that can be brought into alignment with selected channels 10, 15 in a stator 1, Fig, 2. The fluid expelled by the piston is returned through the pipes 19, 21 and ports 30, 31 to an outlet pipe 9 connected to the stator. As the rotor is moved, the ports 30, 31 pass along channels 13 and 15 respectively and the bottle is raised and held against the nozzle while it is evacuated. Subsequently, as the port 30 passes along channel 10 and the port 31 passes along channel 15, high pressure is applied to raise the bottle further and move the pipe upwardly against spring 27 thus allowing liquid to enter the bottle to a level determined by the lower end of tube 24. During the remaining part of the rotation, ports 31, 30 pass along channels 11 and 14 respectively and the bottle is lowered and removed. In an alternative arrangement, Fig. 4, the nozzle is moved down on to the bottle, which remains stationary. The invention may be applied to the operation of a counter pressure bottle filling apparatus. French Specification 994, 101 is referred to.

Abstract: 1,145,348. Coating with glass. INTERNATIONAL BUSINESS MACHINES CORP. 4 May, 1967 [31 May, 1966], No. 20682/67. Heading C1M. [Also in Divisions C7 and H1] A glass film is deposited on a semi-conductor surface, without damaging electrical components formed in the semi-conductor, by sputtering at a power density less than 4 watts per square inch across the anode and cathode which support a glow discharge in the sputtering chamber, then after an initial layer 200 Angstrom units thick has been deposited on the substrate the power density and rate of deposition are increased, as the substrate surface is by then shielded from the higher-energy particles which build up the remainder of the film. The sputtering chamber may be filled with Ar under reduced pressure, and the glow discharge may be concentrated by a magnetic field. Fused quartz, Si dioxide, or Si nitride may be applied instead of glass, and Ge, Si and Group III-V compounds may be employed as substrates. After application of a sputtered layer the surface of the coated semiconductor may be altered by annealing.

Abstract: 384,242. Torpedoes. TENNANT, W. J., 111, Hatton Garden, London.-(Schneider et Cie ; 42, Rue d'Anjou, Paris.) July 23, 1932, No. 20809. [Class 9 (ii).] Relates to torpedoes having a compressedair supply system comprising a storage chamber a, a reducing valve b, a heater d, and an engine g, all connected by pipes c, e, f. According to the invention, part of the air is diverted from the reducing valve b by a pipe i to a separate reducing valve h having a less pressure reducing action than the valve b,-and thence by a pipe j to operate various auxiliary mechanisms such as the engine valves and the rudders in such a way that the exhaust from these auxiliary mechanisms is at a pressure approximating to the pressure of the air fed by the pipe e into the heater d and can therefore be fed into the heater by a pipe k. This arrangement results in a more effective use of the compressed air supply. In a modification, two reducing valves in series are used between the storage chamber a and the heater d, and the supply of air for the auxiliary mechanisms is taken from between the two reducing valves.
