Patent GB-1208479-A (GB)
Title: Improvements in or relating to electronic synchronizing systems
IPC: H02P5/52
Filed: 1968-08-01
Abstract: 1,208,479. Automatic speed control. MAGNAVOX CO. Aug. 1, 1968 [Aug. 17, 1967], No. 36706/68. Heading G3R. In a system for synchronizing the drive motors of facsimile transmission equipment, the receiver drive motor is retroactively controlled until the phase error is reduced below a predetermined value and is thereafter driven by a constant frequency source. The motors are synchronous types and each drives a pulse generator whose output is indicative of the speed and position of the motor. The two pulse outputs are compared in a logic circuit 14 and a control signal generated in the form of a train of pulses whose width is a measure of the phase difference between the drive motors. This control signal is used to gate a counter 34 so that the counter is reset to zero at the beginning of each control pulse and then counts from a clock 32 for the duration of the control pulse. The value on the counter is read by a converter 35 which generates both a speed up and a slow down signal, each dependent upon the phase difference. The appropriate one of these is selected by a series of gates 36-39 and applied to a voltage controlled oscillator 17 feeding the receiver motor. When synchronism is achieved the control pulses disappear and a two stage counter 43 is enabled to begin counting pulses from the receiver pulse generator. When three consecutive control pulses have not appeared a selector 19 switches the motor supply from the voltage controlled oscillator 17 to a fixed frequency oscillator. In an alternative arrangement Fig. 6 (not shown), the control pulses are applied with other pulses from a crystal oscillator to an integrator the output of which controls the frequency of a voltage controlled oscillator feeding the receiver motor. When the control pulses diappear the voltage controlled oscillator continues to run, but in phase synchronism with the crystal oscillator so that no irregularity due to switching is introduced. A short while after synchronism is achieved or after a longer time even if synchronism is not achieved the control signal generator is blocked and thereafter the motor runs only under the control of the crystal oscillator.

Title: Method of and container for ensuring a selective evaporation of the different constituents of a mixture of volatile substances
IPC: B01D53/22
Filed: 1957-11-29
Abstract: In a capsule for ensuring selective evaporation of the different constituents of a mixture of vaporizable substances e.g. perfumes, insecticides and deodorants, contained therein, the permeability of the capsule is different for the different constituents of the mixture, as a result of the chemical structure of the material forming the container, such that evaporation of the mixture, when contained in the capsule takes place substantially independently of the vapour tension of the constituents.  The capsule may be made from plastic material, paper, metal, rubber, preferably used in the form of foils.  The permeability could be modified by treatment by irradiation or by coating the material of the capsule with paint, varnish, or a metallised layer formed by evaporation under vacuum, or else to treat the said surface mechanically by roughening it, perforating it, pressing it between special matrices formed for example with a network pattern.

Abstract: 930,080. Mixing liquids in proportions; aerating liquids. DALE VALVE CO. Nov. 6, 1959, No. 37757/59. Class 86. [Also in Groups VI, XVIII and XXVIII] In an apparatus for mixing and dispensing beverages (see Fig. 1, Group XVIII) the concentrate and water are mixed by a Venturi device in which a flow of pressure water enters by the passage 45 and induces a flow of concentrate through the conduit 57 and jet tube 44, the included angle of the converging portion 45 of the Venturi being 20 degrees to 35 degrees and of the diverging portion 65, 5 degrees to 7¢ degrees. The jet tube is axially adjustable in the body 36 by means of the threads 53, collar 49 and lock-nut 55. Movement of the jet tube towards the throat 46 will reduce the water flow by reason of the co-operation of the tapered portion 63 of the jet tube with the converging portion 45 of the Venturi and hence will increase the proportion of concentrate in the mix. For optimum results the lengths of the converging and diverging portions 45, 65 should respectively be at least ten and three times the diameter of the throat 46. The mixed liquids are aerated by air induced through an aperture 80 behind an annular shoulder 81 which prevents discharge of liquid through the aperture. The spout 21 has a right-angle bend which creates a back pressure to effect priming of the Venturi, which may be made of a transparent (e.g. plastics) material.

A spring 16 is located between the trigger A and the sear B. The sear B, having an elongate aperture 2 therein, is mounted on a pin for pivotal and translational movement, and is biased by the spring 16 into a position in which, after operation of the trigger A, it allows the striker to return to a position where it will be held by said sear. The spring 16 is mounted on and guided by a pin D one end of which is received in a conical recess 6 formed in the sear B and the other end of which passes through a hole 10 formed in the trigger A. The latter has a hole 9 by which it is pivotally mounted on the firearm (not shown). The striker is pivotally mounted on the firearm and is urged by a spring 15. This causes the sear B to be raised to the position shown in Fig. 1, where a tooth 3 of the sear B engages an extension 1 of the striker C and where a lug 8 of the trigger engages a flat 4 on the sear. When the trigger A is squeezed the tooth 3 releases the extension 1 and the striker C is urged by the spring 15 into contact with a firing pin 14. The sear B is then moved by the spring 16 to the position shown in Fig. 3 so that the lug 8 of the trigger is received in a notch 5, Fig. 1, in the sear and the sear is urged against a flat 18, Fig. 3, of the lug 8. When the striker C is returned by bolt 11, Fig. 1, the tooth 3 of the sear again engages the extension 1 of the striker and, on release of the trigger A, the sear is moved to the position shown in Fig. 1 where the lug 8 of the trigger again engages the flat 4 on the sear B.
