Title: Surge protection arrangement for electric plants of low operating voltage
IPC: H01T1/14
Filed: 1929-06-06
Abstract: 328,839. Maschinenfabrik Oerlikon. April 5, 1929, [Convention date]. Protective arrangements for the discharge of surges in electric plants of low operating voltage consist of a central electrode 3 connected to the line through the non-inductive resistance 2 and mounted on an insulator 11 supported by an earthed bracket 9 to co-operate with a pair of arc-horns 4. The arc-horns are carried by an insulator 5 as a unit which may be readily removed. The inner ends of the horns constitute electrodes 7 resting on a perforated insulating plate 8. Replaceable fuses are arranged (in parallel) between the central electrode and the arc-horns. The surge-discharge jumps the gap and the current blows the fuses. The unit 5 may be removed to renew the insulating plate. In a modification, a multi-armed central electrode is employed.

Abstract: 537,856. Automatic gain control. PHILCO RADIO & TELEVISION CORPORATION. June 19, 1939, No. 17861. Convention date, July 16, 1938. [Class 40 (v)] Automatic gain control of a composite signal comprising a first component, whose average amplitude inherently varies, and a seond component, whose average amplitude may vary due to extraneous influences, the components being established on opposite sides of a predetermined level e.g. a television signal comprising background (D.C. component). Video and synchronising components V, S, is obtained by levelling the peaks of the composite signal, deriving therefrom a signal above a constant level and containing the first component and part of the second component, and obtaining from the derived signal a control voltage which is applied to control the gain of the system. Three portions of the signal separated by long intervals are shown at (a) Fig. 3 and comprise respectively normal, weak and strong signals. The first stage of the operation i.e. levelling the peaks of the signal is shown at (b) while the obtained control pulses are shown at (d). The control apparatus comprises a condenser 1 and relatively large resistance 2 connected to the plate of a diode rectifier V1 the output of which is applied to the grid of a valve V2 the bias and plate voltage of which are suitably adjusted by potentiometers 8, 9. The output of this valve produces an amplified voltage across the cathode resistor 7 and is integrated by a filter network comprising condensers 4, 5 and resistor 6. This voltage is then applied as control voltage to a previous stage of the receiver e.g. by feeding it through resistor 17 to the grid of an I.F. valve V5. Values for the condensers 4, 5 and resistors 2, 6, 7, when used with Type 6H6 and 6Q7 valves in the positions V1 and V2 are specified.

As described the body is of silicon, the film of aluminium or copper-aluminium alloy and the ion dosage such that the weight of silicon in the film is À5% of that of the aluminium. In one example the body constitutes the base of a bipolar transistor and arsenic diffused emitter regions 19 Î 10<SP>-6</SP> inch. deep are contacted in the apertures by a film 5000  thick, while in another the source and drain regions of an IGFET underlie the apertures.

Title: Process for manufacture of heterocyclic sulphur compounds
IPC: C07D333/38
Filed: 1942-12-22
Abstract: Compounds of the formula:-<FORM:0562313/IV/1> are prepared by treating dibasic acid esters of the formula:-R1OOC.CH2.S.CH2.CH2.COOR2, where R1 and R2 are alkyl groups, with alkaline condensing agents such as alkali metals and their derivatives, e.g. sodium, sodamide, and sodium ethylate, to effect ring closure with elimination of an alcohol R2OH.  In examples: (1) S-carbethoxyethyl-thioglycollic acid ethyl ester, obtained by treating S-carboxyethylthioglycollic acid with ethyl alcohol and HCl, is dissolved in benzene and heated with sodium.  The mixture is cooled, acidified with H2SO4, and the benzene layer separated, washed, dried, the benzine evaporated, and distilled under reduced pressure to yield 2-carbethoxy-3-ketotetrahydrothiophene.  The sodium may be replaced by sodamide or the solvent dispensed with and the ester treated with sodium and a little ethyl alcohol; (2) S-carbmethoxyethylthioglycollic acid methyl ester in analogous manner yields 2 - carbmethoxy - 3 - keto - tetrahydrothiophene; (3) b -chlorpropionic acid ethyl ester in ethyl alcohol is heated with thioglycollic acid in aqueous caustic soda, and the mixture cooled and acidified.  The precipitated oil is extracted with ether, dried, the ether evaporated and the residue treated with benzene and heated with thionyl chloride.  The product, obtained by distilling under reduced pressure, is S - carbethoxy - ethyl - thioglycollic acid chloride which is converted to the methyl ester with methanol.  This ester is dissolved in benzene and treated with sodium to give 2-carbmethoxy-3-keto-tetrahydrothiophene; (4) S-carbethoxymethyl-thiolpropionic acid methyl ester, prepared as in (3) using b -chlorpropionic methyl ester and treating the acid chloride with ethanol, in similar manner yields 2-carbethoxy-3-keto-tetrahydrothiophene; (5) S-carbmethoxyethyl-thioglycollic acid chloride prepared from b -chlorpropionic methyl ester is treated with n-butanol to give the n-butyl ester which by the action of sodium gives the n-butyl ester of 2-carboxy-3-keto-tetrahydrothiophene; (6) the n-butyl ester of S-carboxyethyl-thioglycollic acid methyl ester, made from S-carbmethoxymethyl-thiolpropionic acid chloride and n-butanol, is reacted with sodium to yield 2-carbmethoxy-3-keto-tetrahydrothiophene; (7) S-carbmethoxymethyl-thiolpropionic acid isopropyl ester, made by reacting b -chlorpropionic isopropyl ester and thioglycollic acid, forming the acid chloride, and treating with methyl alcohol, is treated with sodium to form 2-carbmethoxy-2-keto-tetrahydrothiophene.
