IPC: H03G3/24
Filed: 1946-09-27
Abstract: 631,183. Automatic gain control. COLE, Ltd., E. K., and MARTIN, A. W. Sept. 27, 1946, No. 28860. [Class 40 (v)] In a car radio receiver a control voltage is derived which varies the gain directly as the road noise. As shown, a microphone M is mounted. in a position close to the road and near the engine, and is connected to a valve amplifier, the output of which is rectified by the diode D. The control voltage; which may be varied bv means of resistance R3 is taken from the lead L and fed to the H.F., I.F., or L.F. stages of the receiver. Specification 485,005, [Group XXXIX], is referred to.
Patent GB-408339-A (GB)
Title: Circuit-closing arrangement for the direct-current circuit of controlled rectifiers
IPC: H02M7/15
Filed: 1932-10-17
Abstract: 408,339. Converting alternating current. JACKSON, L. MELLERSH- 28, Southampton Buildings, Chancery Lane, London.-(Siemens-Schuckertwerke Akt. Ges. ; Siemensstadt, Berlin.) Oct. 17, 1932, No. 28991. [Class 38 (ii).] In a method for switching on the continuous current circuit of a grid-controlled gas or vapour discharge device operating as a rectifier or inverter, an auxiliary load is provided in series with the direct current circuit and is automatically bridged only when the current flowing therein is less than a predetermined value. The object of the invention is to prevent the connection of the rectifier to a continuous current circuit if the E.M.F. of the rectifier is sufficiently greater than that of the circuit to cause a heavy current to flow. As shown in connection with a rectifier 1 supplying a motor 4 which may be at rest or running under the action of momentum, the switch 5 is open and is shunted by a circuit comprising a resistance 7, an inductance 8, the coil of a relay 6 and a switch 9. The relay 6 has normally closed contacts 10 in series with the coil of a second relay 11 and normally open contacts in the circuit of a motor 14 which operates a potentiometer 16 to reduce the bias voltage applied to the valve grids 26. In operation the switches 9 and 25 are closed in sequence. If the terminal voltage of the rectifier is greater than that of the motor 4, relay 6 is energized to open contacts 10 and close contacts 12 whereby the motor 14 is connected to the continuous current source 24 and actuates the potentiometer 16. The consequent reduction of the rectifier potential causes the relay 6 to be de-energized so that contacts 12 open and contacts 10 close. The motor 14 therefore stops and the relay 11 is energized to close the circuit of the coil 22 of the main switch 5. The inductance 8 should be such that the ratio L/R is approximately the same in this circuit as in the main circuit when the switch 5 is closed to avoid over-regulation of the grid bias. Other methods of grid control may be employed, and the regulating arrangement may be used for control in normal operation.

Title: Chip board plant
IPC: B27N3/16
Filed: 1961-08-11
Abstract: <PICT:0917340/IV(a)/1> <PICT:0917340/IV(a)/2> A chip board plant comprises a movable band, a forming station for scattering chips on to said band to form a continuous chip fleece, a press for pressing the fleece on the band, and means for effecting relative movement between the band, the forming station and the press.  In one embodiment the relative movement between the band and the forming station is constant, the forming band is moved towards the press when the press is open, and the forming band and press are stationary with respect to each other during a pressing operation.  In a second embodiment, the band is stationary when the press is closed and moves relatively to the press when the press is open, and the band and forming station move with a constant relative movement.  In construction of the apparatus (Fig. 2) the length of the press (10) is equal to the sum of the distance traversed by the band during a complete pressing cycle.  The forming station (8) has a chip scattering outlet which forms a chip fleece which has a thin, rhomboidal cross-section (Fig. 1), the said forming station scattering finer chips at the outside than at the centre whereby the fleece is formed with upper and lower layers of fine chips. Specification 826,399 is referred to.

Abstract: 393,468. Printing &c. machines. WESTERLIN & CO., A. B., 1, Dammevagen, and DANIELSSON, Y. A. F., 4, Ovra Viktoriagatan, both in Gothenburg, Sweden. Oct. 18, 1932, No. 29101. [Class 100 (ii).] Tripping-arrangements.-In a printing or like machine the feeding mechanism or the press, or both, are rendered inoperative in the event of a multiple feed by mechanism which is controlled by the passage of the sheets between a feed roller 5 and a disc 19 which is normally set so that a sheet can pass between it and the roller 5 without rotation of the disc. The sheets are separated from a pile 2 by separators 3, and are carried to the cylinder 1 by a belt 8 passing over the roller 5. The disc 19 is mounted in an arm 14 carried by a sleeve which can be adjusted axially on a shaft 10, and the distance of the disc 19 from the roller 5 is controlled by means of a screw 16 which engages a projection 15 on an arm 22, Fig. 4, which supports a roller 26, Fig. 2, resting on the roller 5 outside of the path of the separated sheets. The arms 14, 22 are adjustable axially simultaneously. When more than a certain number of sheets pass over the roller 5, the disc 19 is moved frictionally by the sheets and a pin 41 on disc 19 moves a double forked lever 30, 31 in a clockwise direction, and a bar 9 carried by arms 9a is depressed and causes the operation of the stopping mechanism. The arm 14 is pressed towards the roller 5 by a spring 39 acting on a fixed bar 40 and a plunger-shaped casing 38 on an arm 36 fixed to the hub of the arm 14. The movement of the disc 19 is limited by the action of the pin 41 on abutments 42, 43, and the disc is formed with a flat portion 20 which permits withdrawal of the excessive sheets.

Title: Improvements in impulse controlling arrangements for use in electrical signalling systems
IPC: H04L25/04
Filed: 1928-10-11
Abstract: 323,804. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Oct. 11, 1928. Automatic exchange systems. - Selector-controlling impulses or like signals which consist of trains of alternating current and which arrive incorrectly spaced or otherwise distorted are corrected by means of a low pressure discharge tube containing one or more gases of the Neon, Helium, Argon type. As shown, the tube 6 is kept near its breakdown voltage by a battery 9 and is shunted by a condenser 7 and repeating relay 10. The arrival of a signal impulse via the filter 4 causes the tube to break down and allows the condenser to discharge through the relay. The tube then becomes non-conducting until the condenser is charged again and a new signal arrives. By adjusting the size of condenser 7 and resistance 8 the charge and discharge times of the condenser can be adjusted so that correct impulses are produced by relay 10 irrespective of the distortion of the incoming signals, and even if the signal takes the form of one long impulse.
