Title: Improvements in or relating to sound recording apparatus
IPC: G11B7/00
Filed: 1932-05-23
Abstract: 406,635. Recording sound. RADIO CORPORATION OF AMERICA, 570, Lexing- ton Avenue, New York, U.S.A.-(Assignees of Kreuzer, B. ; 120, Newport Avenue, Rockaway Park, Long Island, New York, U.S.A.) May 23, 1932, No. 14578. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 26, 1932]. [Class 40 (ii).] In an amplifier for use in sound recording, the rate of increase of direct-current output is controllable separately from the rate of decrease in output. Fig. 1 shows a rectifier 1 having a resistance 9 in series in the charging circuit of condenser 3, the discharge of which is controlled by resistance 2. The voltage across condenser 3 is derived from the signal and applied to a valve 6 effecting a required control. Fig. 5 shows the application of the control through the valve 6 to control a recording amplifier. The valve 62 is biassed through a resistance in the output of the transformer 63 which thus varies in direction and amplitude upon the changes in current in the transformer primary. Fig. 3 shows the application of the control 60 to the magnetic control member 62 of the shutter 61 masking the unused area of a variable area sound record. In variable density recording the control is effected by changing the potential applied to the light valve or lamp or other density determining means. A delay circuit 63 may be included in the recorder circuit to give the amplifier 60 time to operate and may be of the electrical or mechanical type. In a modification (Fig. 4 not shown) using a main amplifier of the type shown in Fig. 5, the control is connected back to the main amplifier so as to preclude " overshooting " of the sound track by the recorder.

Title: Improvements in or relating to apparatus for the manufacture of potentiometers and rheostats
IPC: H01C17/04
Filed: 1945-06-11
Abstract: 606,430. Coiling, SPERRY GYROSCOPE CO., Inc. June 11, 1945, No. 14803. Convention date, June 9, 1944. [Class 83 (iv)] [Also in Groups XXXVI [Appx.], XXXVII and XXXVIII] In a potentiometer winder, resistance cards are automatically wound to conform to a master potentiometer. During winding the potentiometer is continuouslv balanced in a bridge against the appropriate fraction of the standard, the out-ofbalance voltage operating a motor which varies the winding pitch in the corrective sense and so balances the bridge automatically. In Fig. 1, the winding former 27 is rotated by shaft 16 driven through gears 51, 52 and differential 45 from motor 12 which also operates the lead screw 21 through gearing 44. The bare resistance wire 26 is fed from a supply spool (not shown) to the former 27 by carriage 28, movably supported on crossrod 19 and lead screw 21, and provided with thread-engaging mechanism 29. To vary the speed of rotation of former 27 with respect to that of the lead screw 21, the error correction motor 13 is coupled to shaft 16 through gears 46 and differential 45. Speed control thereof is achieved by two permanent-magnet generators 53, 54 driven by motors 12, 13 respectively in conjunction with the control apparatus 14, [see Group XXXVII]. The master potentiometer 55 is varied progressively, as wire is fed to the cord 27, by lead screw 21 through gearing 59 and cam 61 which is shaped to give the desired function.

Title: Improvements relating to fire-extinguishing sprinkler systems
IPC: A62C35/64
Filed: 1929-05-11
Abstract: 328,465. Burgess, A. F., (Automaatic Sprinkler Co. of America). May 11, 1929. Alarms operated by expansion of gases, by change of gas pressure, by flowing liquid, and by movement of working parts of extinguishing apparatus.-In a sprinkler system the distributing pipe 6 provided with fusible heads 22 is charged with air under pressure. A supplemental tubing system 26 arranged in the area to be protected is provided with air bulbs 28 and is also charged with air under pressure. The main valve 10 opens when byepass water pressure in a chamber 18 is relieved by a valve 25 being opened. The valve 25 is opened through the agency of a diaphragm 32 when the air in the tubing 26 is expanded by the heat of a fire. When it opens, a switch 46 in an electric alarm circuit 48 is operated, and water parses to operate an alarm gong 54. A further alarm is operated when pressure falls in the distributing piping 6. To this end, a piping 84, 62, 89 connects the piping 6 with a bellows 88. Collapse ot the bellows opens a valve 94, permitting water to pass to an alarm gong 96. This gong is also operated by a pressure fall in the tubing 26, for example owing to leakage.
Patent GB-1031769-A (GB)
Title: Improvements in electronic switching circuits
IPC: G06F7/50
Filed: 1963-04-16
Abstract: 1,031,769. Switching and logic circuits. INTERNATIONAL BUSINESS MACHINES. CORPORATION. April 16, 1963 [April 20, 1962], No. 14837/63. Heading H3T. A logic and switching circuit comprises two transistors in series across a supply with the common junction point connected to the base of a third transistor, the second and third transistors having a common emitter resistor, and the voltages being arranged so that when the first and second transistors are conducting at a high level the third is cut off, and when the third is conducting the first and second conduct at a lower level. In Fig. 1 application of a positive pulse to 24 causes an increase in the potential at 38 which is passed to the base of 60 to turn it on. The current through the common emitter resistor 44 then reduces the current in transistor 30 which thus exhibits a negative resistance characteristic (curve 80 in Fig. 2, not shown). A negative output pulse is thus obtained at terminal 69. If positive pulses are applied simultaneously to 24 and 74, transistor 70 will conduct and supply current through the emitter resistor 44, so that the collector current of 60 scarcely changes and no negative output is obtained. The arrangement thus acts as an inverted BUT NOT circuit. A number of parallel inputs can be applied simultaneously at 24 and 74 to give a logic output corresponding to (A 1  + A 2  . . - A n ) + (B 1  + B 2  ... B n ), i.e. a NOR function overridden by an OR function. In an alternative version (Fig. 3, not shown) the transistor 70 is replaced by a transistor 100 in series with 60, the source 51 is omitted and the resistor 52 is transferred to the lead 26 so that outputs are obtainable at the collectors of transistors 20 and 100. With positive significant inputs at A and B the output at the collector 100 is A À #B and at the collector of 20 is #A+#B. To obtain an Exclusive-OR function (Fig. 6, not shown) the circuit of Fig. 1 is modified by omitting the source 51 and joining the base of 30 to a further transistor which receives the B signal. Transistor 70 may be retained if a further inhibit function is required. The Exclusive-OR output is obtained at the collector of transistor 20 and its complement at the collector of transistor 60.

Filed: 1927-06-02
Abstract: 272,223. Skoda Works, Plzen. June 4, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Projectile fuzes.-The trigger mechanism for the spring striker of a clockwork fuze or like device is made with a series of levers or other members adapted to reduce the pressure at the point of release. As shown in Fig. 1, the spring striker 1 is supported by a centrifugal bolt 3 bearing against a spindle 4 which is formed with a notch 7 for the release of the bolt 3 and is provided with a lever 5 riding against the timing drum 6 of the clockwork. In another form, Fig. 5, the centrifugal bolt 3 bears against a flat 14 on a spindle 13 provided with a lever 11, which in its turn bears against a flat 7 on the spindle 4 carrying the release lever 6. The flats 7, 14 act as short levers reducing the pressure required between the lever 6 and the drum of the clockwork. Various other arrangements of levers and bolts of a similar kind are described.

Filed: 1968-03-28
Abstract: 1,218,935. Filter with bypass valve. ROSAEN FILTER CO. 28 March, 1968 [19 June, 1967], No. 14918/68. Heading B1D. A conduit 14 opening to a liquid reservoir below the liquid level 30 is surrounded by a perforated tube 32 whose upper end is above the level 30; a hollow filter element 58 (which can be inserted through the upper end of tube 32) is disposed coaxially within tube 32 with its lower end in communication with conduit 14. In normal use liquid flows inwards through filter element 58 and out at 14; when the filter element clogs the resulting pressure increase forces a bypass valve member 76 to slide on a concentric guide rod 70 against bias means 80 to allow liquid to enter filter element 58 directly through its upper end. As described, downward movement of valve member 76 causes movement of a tube 74, which is converted by a pin-and-helical-slot arrangement 108, 110 to rotary movement of a pointer 112 which indicates the degree of filter clogging on a scale 94. When the filter is bypassing, filtration occurs through a coarse strainer 82, 46.
