Patent GB-957576-A (GB)
Title: Voltage regulators
Inventor: ADAMS DEREK STANLEY
IPC: H02P9/30
Filed: 1962-04-11
Abstract: 957,576. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. April 3, 1963 [April 11, 1962],No. 13942/62. Heading G3R. A voltage regulator for a generator 8 supplying a D.C. load 9 includes a first transistor 15 having its emitter connected one output terminal 6 through a resistor 16 andto the other output terminal 7 through a Zener diode 17, and a second transistor 18 of opposite conductivity type to transistor 15 and having its emitter connected to a field winding 19 of the generator 8, its collector connected to terminal 6 over a diode 10, and its base connected to the collector of transistor 15. When the output voltage is low, the potential divider constituted by diode 10 and a resistor 11 maintains the collector voltage of transistor 18 negative with respect to the emitter voltage of transistor 15 which is thereby rendered conductive so that transistor 18 is also held on so that current flows in the winding 19. When the output voltage reaches a certain value as determined by the adjustable setting on a resistance chain 12, 13, 14, the Zener diode 17 breaks down and the emitter voltage of transistor 15 is held constant; any further rise in the collector voltage of transistor 18 results in the switching-off of the transistor 15, with consequential switching-off of the transistor 18, whereby the field current of the generator is controlled to maintain a constant output voltage. It is stated that the diode 10 serves to provide positive feedback between the transistors 15 and 18 whilst maintaining the change in collector voltage of the transistor 18 reasonably small, so that the change from the conductive to non-conductive state is rapid. The transistors 15 and 18, or these transistors and the diode 10, may be constituted by a single semi-conductor crystal (Figs. 2 and 3, not shown). Temperature compensation can be effected by using a temperature sensitive resistor in the resistance chain 12, 13, 14.

Title: Improved process for copying documents
IPC: G03C1/52
Filed: 1932-05-17
Abstract: 390,341. Copying documents. SCH€TZLER, E., 2, Gotthardstrasse, Basle, Switzerland. May 17, 1932, No. 14078. [Class 100 (ii).] In a process for printing copies from an original document written in reversed script, moisture, e.g. spirit, alcohol, or water, is applied to the rear side of the sheet, and copy sheets are pressed against the front side of the sheet in a separate operation. Since, during the printing operation, no moistening is necessary, the usual moistening-bar may be dispensed with whereby the heading of the copy sheet may be printed and copy sheets of small size may be used. Further, since it is not necessary to moisten the copy sheets, thin or perforated paper may be employed.

Title: Frenquency analysing signals
IPC: G10L25/90
Filed: 1965-04-05
Abstract: 1,034,757. Speech recognition apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 5, 1965 [May 18, 1964], No. 14262/65. Heading G4R. In apparatus for determining the frequency of a resonant peak in a signal having a wide frequency band, the logarithm of the power in each of a number of frequency channels is measured, the measurements are weighted and linearly combined and the resulting signal fed to an indicator adapted to indicate the frequency of the or each peak. In the form described, the signal from source 10, Fig. 5A (not shown), is split into 36 channels by band-pass filters 20-1 to 20-36. The output of each filter passes to a square-law detector 30-1 &c. to derive a signal representing the power in the corresponding channel. After smoothing at 40-1 &c. the logarithm of the power signal is obtained at 50-1 &c. The 36 log. power signals pass to each of 55 linear combinors 60-1 &c., Fig. 5B (not shown). Each of the incoming signals is weighted by a potential divider 70-1 &c., Fig. 6 (not shown), and the weightings are adjusted so that the combined output signal is a voltage proportional to the numoer of formants below a specified frequency. Each linear combinor circuit 60-1 &c. has a different specified frequency. If there is one formant below the given frequency an output of 1 volt is obtained, 2 volts for 2 formants and 3 volts for 3 formants. The outputs of each combiner circuits 60-1 &c. is applied to the three threshold devices 81-1 &c., 82-1 &c., Fig. 5C (not shown), and 83-1 &c., Fig. 5D (not shown), having levels 0À5 v.,1À5 v. and 2À5 v. Those combiner circuits indicating that there is one formant below the corresponding frequency give an output from the associated threshold device 81-1 &c. Those indicating two formants give an output from threshold device 82-1 &c. and those indicating three formants give an output from threshold devices 83-1 &c. The exact frequency of these formants is found by inverting the output from each threshold device and gating it with the output from the one above. The gates 101-1 &c., 102-1 &c., 103-1 respond to indicate the frequency band in which lie the first, second and third formants. Indicators 111-1 &c., 112-1 &c. and 113-1 &c. may be printers, lamps or counters.

Abstract: 621,677. Shearing; punching. BRITISH THOMSON-HOUSTON CO., Ltd. June 7, 1945, No. 14353. Convention date, June 8, 1944. [Class 83 (iv)] A machine for shearing a metal strip into unequal lengths and holing it near the centre has a shear-blade 22 fixed in position and a punch 67 and an end stop 27 movable by screws. The shear-blade 22 is reciprocated by an air cylinder 65 fed from air lines 64, 70. The punch is actuated by a cylinder 67 and is slidable on rods 28, 29 on rotation of a screw 33. The end stop 27 is slidable on the rod 29 and is positioned by rotation of a screw 34. To cut a succession of lengths, a pedal 61 is depressed to operate a valve 62 to actuate the shear and the punch and a cylinder 68 to lower a rack 40. On reversal of the valve, the rack rises and ratchets 47 turn the screws 33, 34. By variation of gearing 52, 53, 54 the relative adjustment of the end stop and punch is determined. The position of a stop-nut 73 adjusts the length of stroke of the rack. A dashpot 82 prevents feed movement of the rack during operation of the punch and the shear. Specification 621,676 is referred to.

Title: Stay device
IPC: E05F1/00
Filed: 1960-04-26
Abstract: 902,438. Stays. FISH, K. R. G. April 25, 1961 [April 26, 1960], No. 14583/60. Class 65 (1). A stay for holding a hinged closure, such as the lid of a cold-frame, in a desired open position comprises relatively movable members adapted to be held in a set position by detent means which are released, upon the ambient temperature falling to a predetermined value, by temperature-responsive means to permit the stay to collapse and the closure to close. The relatively movable members may consist of a pair of pivoted arms, but preferably consist of relatively slidable telescopic tubes. As shown in Figs. 1 and 2, an outer tube 1 is pivoted at its lower end to a rod 5 adapted to be stuck into the ground and contains an inner tube 2 to the top of which is secured a right-angled bracket 9 having a short limb 9a which embraces the tube and a long limb 9b pivoted at 26 to the hollow casing 22 of a thermostat. The thermostat comprises a temperature-responsive strip 23, adjustable by means of a screw 25, which carries one contact 24a of a switch 24. When the temperature falls to the predetermined value the switch 24 closes the circuit of a solenoid 19, powered by dry cells 20 located inside the tube 2, which raises a plunger 18 and disconnects a catch 17 which is pivoted to the limb 9a at 16 and engages the casing 22 at 22a. On its release the casing 22 is forced away from the limb 9b by the action of a compression-spring 28 and swings outwardly about the pivot 26 carrying with it a detent 27 engaged with one of a series of ratchet teeth 3 on the side of the outer tube 1. The release of the detent 27 frees the tube 2 which then falls under the weight of the closure 12, a washer 7 being fitted to the bottom of the tube 2 so that the space S inside the tube 1 acts as a dashpot chamber, the wall of which is provided with a small air vent 8. The circuit of the solenoid 19, which may be powered by an accumulator or from the main supply instead of by the cells 20, is arranged to be broken by the movement of the casing 22, and may be adapted also to switch on a heater inside the frame 13. In a modification, Fig. 6, a detent 27<SP>1</SP> pivoted to the longer limb 29b of a bracket 29 secured to the inner tube 2 is locked in its operative position by a rod 30 which is raised by a rocking- lever 31 connected to the plunger 32 of the solenoid 19 when the latter is energized by the thermostat.

Abstract: 1,140,943. Switch contacts. SIEMENSSCHUCKERTWERKE A.G. 1 April, 1966 [1 April, 1965], No. 14705/66. Heading H1N. [Also in Division C7] A sintered metal compact such as an electrical contact e.g. a switch pin or a tulip shaped switch is made by compacting at least two layers of metal powder consisting of at least one of W, Mo and Re, the compacting pressure of the layers being different when adjacent layers are of the same composition, sintering the compact and then impregnating with Ag or Cu or their alloys. When the layers are of different composition the compacting pressure may be the same for each layer. As shown in Fig. 1d a metal powder layer 3 is first compacted in the die 1, a second layer 5 is then compacted at a lower pressure followed by layers 7 and 9, the shape of the layers being determined by the movable top punch. Each pressed layer may have its upper surface loosened or roughened prior to the introduction of the next powder layer. After sintering impregnation with Cu or Ag is carried out in a graphite or ceramic mould. The following systems may be made: W-Cu; W-Ag; Mo-Cu; Mo-Ag; W-Mo-Ag; Re-Cu; Re-Ag. The system M 1 -M 2 -M 3  in which M 1  is W, Mo or Re, M 2  is Cu or Ag or their alloys and M 3  is Ni, Fe, Co or Cr may also be produced.
