Title: Improvements in instruments for measuring or indicating transient abnormal electric alternating currents
IPC: G01R1/30
Filed: 1937-04-01
Abstract: 482,784. Current measurements ; magnetic tests and measurements. REICH, E., and GENERAL ELECTRIC CO., Ltd. April 1, 1937, No. 9294. Convention date, April 2, 1936. [Class 37] An instrument for measuring or indicating transient abnormal alternating currents comprises a pair of parallel plates I of hardened steel having bent end portions between which is an armature 2. A coiled spring 10 biasses the pointer 4 towards a zero position. The plates 1 each have a winding 5, which windings are connected in series with the secondary circuit of a current transformer 7 having an open core. A rectifier 6 is connected in the series circuit of the coils 5. The plates 1 need not be integral or magnetically connected at the ends remote from the moving iron assembly. An adjustable buffer 8 is provided on the core 7 in order to vary the range. On passage of a large current impulse through the conductor 9 against which the buffer 8 is pressed, the plates 1, being permanent, remain magnetized to an extent depending on the value of the impulse current, which is indicated by the pointer 4. The plates 1 are then de-magnetized by any known method. In a modification, a primary winding is provided on the core of the transformer, which winding is inserted in the circuit to be tested. For measuring the rupturing capacity of a circuit-breaker, a current proportional to the voltage in the circuit of the breaker is passed through the windings 5, the instrument indicating the maximum voltage attained. The maximum current is measured on a separate instrument. The Specification as open to inspection under Sect. 91 comprises also an instrument for use on a direct current circuit or with an alternating current if the circuit is broken when the current curve next passes through zero after the peak value to be measured. In this instrument the plates 1, Fig. 1 (Cancelled), are applied directly to the conductor 9 and are magnetized by the magnetic field surrounding it. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to methods of manufacturing semi-conductive bodies
IPC: H01L21/368
Filed: 1955-03-31
Abstract: 784,431. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 31, 1955 [April 1, 1954], No. 9425/55. Class 37. Apparatus for manufacturing semi-conductive bodies having p-n junctions comprises a tubular container 1 having a contraction 2 terminating in a bulb 3 which contains sulphur 4, the main charge 5 of lead sulphide being contained in a vessel 6 of sintered aluminium oxide. The container 1 is exhausted and the part containing vessel 6 is heated to 500 C. by a carbon furnace 9 and the sulphur 4 is heated to a temperature of 444 C. by an electric oven 8 to produce a sulphur vapour pressure of 1 atm. in the whole of the container. The temperature of the lead sulphide 5 is increased to 1150 C. by a high-frequency coil 7 which is moved from left to right at a speed of 1 mm. per minute. The lead sulphide solidifying at the edge of the melting zone exhibits p conductivity since sulphur is included in the lattice at a concentration higher than that corresponding to the stoichiometric lead sulphide. After the molten zone has traversed about half of the charge the coil is stopped and the oven 8 cooled to a temperature of 400 C., the vapour pressure of the sulphur thus being decreased to 0.4 atm. and the coil 7 is set in movement again. Lead sulphide of n-type conductivity now solidifies at the edge of the melting zone due to the sulphur pressure of 0.4 atm. being in equilibrium with a melt containing a smaller amount of sulphur than corresponds to the stoichiometric lead sulphide. After cooling, the charge 5 in the form of a rod is removed. Instead of the materials previously described a quantity of cadmium is placed in bulb 3 and a vessel 6 of graphite contains cadmium telluride and indium is added to the left-hand side of the charge to an amount such that, when a zone 2 cms, wide is provided by melting an indium concentration of 10<SP>19</SP> atoms per c.c. is obtained. After being exhausted, vessel 1 is heated to 900  C. by oven 9 and bulb 3 is heated to 750 C. by oven 8 to produce a cadmium vapour pressure of 1 atm. in the whole vessel. A zone of the charge is then melted at 1040 C. by coil 7 which is moved from left to right at 5 mms. per minute and after half of the charge has been traversed, the temperature of the cadmium in bulb 3 is reduced to 650 C. to lower the cadmium vapour pressure to 0.3 atm. The part of the charge which solidifies at a pressure of 1 atm. is n-conductive and the remainder solidifying at 0.3 atm. pressure is p-conductive. In a still further embodiment a charge of lead sulphide containing 0.5 per cent of silver is heated in a sealed vessel by a moving coil, the vessel having inlet and outlet connections for a gas flow of H 2 S to provide a p-type material and a mixture of H 2  and H 2 S to provide n-type material.

Title: Improvements in or relating to electronic scanning apparatus for television and likesystems
IPC: H01J31/34
Filed: 1950-04-20
Abstract: 674,678. Cathode-ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. April 20, 1950 [April 25, 1949], No. 9708/50. Class 39 (i). Electronic scanning apparatus comprises a target electrode consisting of a thin layer of an insulating material which becomes conductive when struck by high velocity electrons placed between a transparent conducting layer and a layer of material of high secondary emission ratio, an electron image of a scene to be transmitted being incident on the target and rendering it locally conductive and a cathode-ray beam scanning the target which has such a positive potential that the coefficient of secondary emission of the beam is less than unity. In Fig. 1, the target comprises three layers, a conductive layer M, a layer I of insulating material, e.g. alumina, silica or mica so thin, e.g. less than 1 micron, that it becomes conductive when impacted by high velocity electrons and a thin layer S of a highly secondary emissive material such as magnesium oxide. High velocity electrons produced at the photocathode P by the image strike layer I and make it conductive. The potential of a source U connected through the load impedance Z to the metallic layer M renders the latter a few volts positive relative to the cathode K and the photo electrons from P have a double effect charging S positively by conduction from M and by the secondary emission of the photo electrons. The scanning beam discharges the charged area owing to the coefficient of secondary emission being less than unity and produces a signal in the plate M both by direct conduction and by capacitative connection between layers M and S, the latter predominating. The scanning beam may be modulated with the carrier frequency, and the load impedance connected to the metallic layer may comprise a tuned circuit resonating at the carrier frequency.

Title: Control systems for evacuated glow discharge vessels
IPC: C23C8/36
Filed: 1956-03-28
Abstract: 807,345. Supply systems for discharge vessels. DORTMUND - HORDER HUTTENUNION A.G. March 28, 1956 [April 2, 1955], No. 9723/56. Class 38 (4). In a supply system for a glow discharge vessel, alteration of the circuit conditions on an arc being struck are utilized to initiate a switching process to temporarily reduce the voltage across the vessel to extinguish the arc. In the system shown in Fig. 1, a vessel 10 having electrodes 11, 12 is fed from grid-controlled rectifier 26 through resistor 29. A series combination comprising capacitor 38, polarized relay 37 and resistor 39 is connected across the electrodes, together with resistor 36. Increased current through resistor 29 due to an arc discharge causes the p.d. across resistor 36 to fall, discharging capacitor 36 through relay 37 and reducing the voltage on rectifier grids 28, thus blocking the rectifier and extinguishing the arc. Operating and holding times of relay 37 are determined by the time constant of component 36-40. When discharge of capacitor 38 is completed, relay 37 releases, re-establishing normal circuit conditions. In an alternative circuit, Fig. 2, a D.C. source 43 is connected to vessel 10-13 through resistors 44, 45. A normally non-conducting triode 47 in series with a resistor 49 shunts the D.C. source and function 57 is connected to terminal 58 by capacitor 46. Increase of p.d. across resistor 45, due to arc discharge, fires the triode through amplifier 53, discharging capacitor 46 which has been previously charged over resistor 49, to cause a temporary extinction of the discharge. On the p.d. across resistor 45 dropping, triode 47 will be again rendered non-conductive and normal circuit conditions restored. A thyratron, an ignitron, an electromechanical switch or a Marx spark-gap switch may be used in place of triode 47.

Title: Frame synchronizing device
Inventor: MORITA TETSUYA
IPC: H04L7/08
Filed: 1987-01-08
Abstract: PURPOSE:To minimize the effect due to out of synchronization by inserting the frame start code of a prescribed bit pattern to which one bit takes at least one logic state to a frame outputted from a parallel/serial conversion means so as to send a signal through other channel even if a transmission error takes place other than the frame start pattern. CONSTITUTION:A FIFO 24 receives a bit serial data from a 15-channel line 20. The data fetching timing of the FIFO 24 is regulated by an enable signal 32 from a control circuit 30 driven by a clock 46 generated by a local oscillation circuit 28. The parallel/serial conversion circuit 26 receives an output 32 from the FIFO 24 to generate a frame shown in figure and outputs it to an output 22 in bit serial. Plural bits (in this example, 5-bit of '01111') representing the frame start pattern 10 are inputted fixedly to the leading in the serial advancing direction of the parallel conversion circuit 26. That is, at least one bit in the plural bits takes one logic state and the prescribed logic takes the logic interrupting the continuity of the bit logic state before and after the bit insertion.

Title: Processing plant and valve assembly
Inventor: RUDORUFU SHIENKU
IPC: C02F9/00
Filed: 1994-01-11
Abstract: A liquid treatment plant has several appliances (3, 4, 5) connected in parallel for handling the liquid. These appliances (3, 4, 5) can have different cross-sections. Of three appliances, two (4, 5) are connected in series with one valve device (6, 7) each. These valve devices (6, 7) act as hydraulic limit-value switches and have a valve body (19a, 19b) which is preloaded by a spring and closes the passage through the valve device (6, 7) in its inoperative state. Up to a certain liquid consumption, the liquid flows solely through one appliance (3). As soon as the demand for liquid exceeds a predeterminable value, the pressure difference arising between inlet and outlet of the appliance (3) opens one of the two valve devices (7) so that the liquid flows through a second appliance (5). If the consumption increases still further, the second valve device (6) also opens at a certain pressure drop. Such a design of the liquid treatment plant ensures that liquid passes through the individual appliances (3, 4, 5) as a function of the liquid consumption and that the individual appliances (3, 4, 5) consequently have good efficiency. <IMAGE>
