Patent GB-633167-A (GB)
Title: Improvements in or relating to an audiometer
Filed: 1947-08-06
Abstract: 633,167. Testing hearing. PATENT MANAGEMENT, Inc. Aug. 6, 1947, No. 21383. Convention date, Feb. 23, 1939. [Class 81(ii)] An audiometer is provided with compensating resistances 28 so that the calibration of the potentiometer 24 controlling the output remains the same for all frequencies. The frequency of the oscillator 3 is determined by a tuned circuit comprising a condenser 15 and a portion of a coil 10 controlled by a switch 14. The potentiometer tapping 25 is connected to output terminals through an amplifying valve 4 and a transformer 22. The output of any particular frequency from the tuned circuit is fed to the potentiometer through a switch 27 mechanically coupled to the switch 14 and through a compensating resistance 28 peculiar to the frequency. The resistances 28 are chosen so that the output remains constant as the frequency is changed. For the purpose of adjusting the resistances 28, the output may be measured as a voltage either at the potentiometer tapping or at the terminals 23 or as a sound intensity given by the reproducer employed. As both the output of the oscillator and the sound level required from the audiometer fall away at the extremities of the frequency range, corresponding terminals are connected directly to intermediate points such as 70 and 80 on the potentiometer.
Patent GB-1422700-A (GB)
Title: Transformer on-load tap changing system
IPC: H03K17/723
Filed: 1973-05-04
Abstract: 1422700 Transformers TBANSFORMATOREN UNION AG 4 May 1973 [4 May 1972] 21386/73 Heading HIT An on-load tap-changing system comprises two sets of controllable rectifiers 7, 8 each connectible between the load 6 and one of two tap selector arms 4, 5 connected to taps 2, 3 of a transformer 1. The set 7 is controllable by a control unit 9 respective to the voltage drop across the other set 8; similarly the set 8 is controllable by a control unit 10 responsive to the voltage drop across the set 7. Each control unit generates an initial firing pulse triggered by the input voltage drop to turn on its associated rectifier set and a further continuous firing current to maintain the rectifiers conductive, e.g. in case of a momentary interruption of mains voltage.  Changeover is initiated by a switch 11 which applies to the appropriate control unit (e.g. 9) control power generated by a power inverter 13 from an independent source maintained at a harmless potential and connected to the switch 11 via an isolating transformer 14. When control power is applied to the control unit 9 via the switch contact 111, alternating voltage from across terminals A2, B2 is limited by reference diodes (17, Fig. 2, not shown) and rectified (18). The resultant full-wave pulses are amplified (19) and fed via a RC delay (20, 21) to a monostable trigger and pulse-shaper (22, 23, 24) and thence to a pulse transformer (25) which fires an auxiliary thyristor (28, Fig. 3, not shown). This discharges a capacitor (33) through a transformer (36) having secondaries (37) each connected to the gate terminal of one of the controllable rectifiers 7. A further secondary (38) of the transformer (36) fires a further thyristor (40) which connects control power to two transformers (41, 42) respectively in series with a resistor (47) and an inductor (48). Three-phase signals derived from secondaries (49, 50) of these transformers are rectified in bridges (51), each bridge thereby supplying continuous firing current to one of the controllable rectifiers 7. Continuous firing current is blocked from the firing-pulse secondaries (37) by diodes (39) in series with these secondaries. The time-delay circuit (20, 21) is designed to delay the firing of the rectifiers 7 until the rectifiers 8 have recovered after the last zero passage of load current following the operation of the changeover switch 11.

Abstract: 597,492. Calculating apparatus. BARRETT, J. G. Aug. 21, 1945, No. 21398. [Class 106 (i)] Apparatus for imparting differential digitregistering movements to a registering member such as a rack or slide, comprises an operating device 6, 7 movable to an extent representing the maximum digit to be registered, and carrying a column of digit-representing actuators 8, each of which is permitted a lost motion relative to the operating device equivalent to the difference between the amount to be registered and the digit of maximum value, and means for rendering the actuators effective selectively in accordance with the digit to be registered, the movement of any selected actuator being imparted to a registering member 1 and being equal to the movement of the operating device 6, 7, less the lost motion permitted to the actuator. In the embodiment described, one of a column of Bowden cables 11, operated from the sensing pins of record card analysing mechanism is adapted to withdraw a selecting pin 2 whose movement is followed by a spring- urged actuator 8. At the beginning of the cycle, pivoted fingers 4 are spring-urged to engage the sides of the actuators 8, but when a selected actuator 8x is withdrawn, its associated finger 4 swings counterclockwise into alignment with the actuator. The frame 6, 7 is then moved to the left and, when the lost motion between a collar 10x and the frame plate 7 has been taken up, it transmits movement through the finger 4x to a registering plate 1 which is mounted for parallel motion on bell-crank levers 12 which give a magnified movement to a rack 3 engaging an accumulator or type wheel. During the return stroke of the frame 6, 7, downward movement of a shutter 5 restores the displaced finger 4 to its initial position.

Abstract: 279,033. I. G. Farbenindustrie Akt.- Ges. Oct. 16, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Apparatus for making films.-In the manufacture of films for photographic and kinematograph purposes the production of the film base and the operations of applying thereon substratum and other coatings with intermediate drying operations are carried out in daylight and in one continuous process thereby avoiding rolling up the film at intermediate stages of production. The further operations of sensitizing the film, inspecting it, perforating it or cutting it up may also be included in the one continuous process of production. For the latter operations the film is passed into a chamber from which actinic light is excluded. The diagrammatic drawings accompanying the Specification illustrate the formation of the film base by flowing apparatus comprising an endless metal band within a surrounding casing, the film base passing over coating rollers and over drying drums and through drying channels at various stages of production. After the sensitizing coating is applied the film is looped over a series of rollers for drying before passing through inspection apparatus, and on to the cutting and perforating apparatus.

Abstract: 1,243,574. Hypodermic syringe. O. H. BANKER. 28 April, 1969 [2 May, 1968], No. 21646/69. Heading A5R. A fluid operated inoculator instrument includes an inoculant pump 20 readily disconnectable from a hollow body 10, the pump having a piston rod 30 extending into the hollow body and connected to an operating piston 31 by a quickly releasable means having a control element 46 operable by means extending to the exterior of the inoculator. As described the gun is operated by compressed gas from a bottle 13 in the handle 12 acting on operating piston 31 which engages a shoulder or rod 33 and moves it to the left (as shown) together with pump piston rod 30 carrying pump piston 29 to eject medicament from pump chamber 24 via nozzle orifice 23. The pump 20 is attached to the gun body 10 by bayonet fittings 21. The pump piston rod 30 is releasably secured to hollow operating rod 33 by balls 42 in openings 43 in rod 33 which engage groove 44 in the piston rod 30 and are prevented from moving outwards by control sleeve 46 held in position by spring 49. To release the pump piston rod, pressure on button 54 moves rod 52 to the left engaging pin 47 and moving sleeve 46 to the left against spring 49, and when the portion of sleeve 46 of enlarged inner diameter is above holes 43 the balls may move outwardly releasing piston rod 30. The dose ejected from chamber 24 may be altered by a gauging device 36 which alters the distance of travel in the chamber 24 of piston 29. This is achieved by inserting or removing shims 63 between the end wall 62 of the gun body or a plate 66 on that wall and a flange 35 on the hollow operating rod 33 to limit the distance of travel of that rod. The shims are pivoted on pin 59 and retained in place by nut 64. The shims are preferably hook shaped.
