Title: Signal transmission system
IPC: G08C19/22
Filed: 1975-06-12
Abstract: 1488304 Signal transmission system YOKOGAWA ELECTRIC WORKS Ltd 12 June 1975 [20 June 1974 (2)] 25196/75 Heading H4R In a signal transmission system, e.g. for conveying a signal between a field instrument and a central controller, a converter in the transmitter develops a pulse width signal corresponding in a predetermined manner to the value of a signal to be transmitted and causes a transmission signal polarity to be reversed for the duration of the pulse width signal, the receiver developing an output signal with a duration proportional to the duration of the reversal. Power for the operation of either the transmitter or receiver is derived from the transmission signal, the power for which is derived from either the receiver or transmitter. As shown in Fig. 1 a signal to be transmitted is applied to terminal 4 of transmitter 1 for transmission to the receiver 3. Transmission is initiated at the receiver by movement of switch S 1 to position a connecting battery E2 to the line via diode D2, the circuit being completed at the transmitter via the transmitter via the switch S0 and diode D0. The diodes are preferred LED's in photo couplers and the output of the photo detector of diode D0 causes the converter CONV to start a timing cycle, which terminates after a duration dependent on the input signal at 4 and causes opening of switch S0. Cessation of current flow in the circuit is detected by the photo detector coupled to diode D2 in the receiver and, via drive circuit DR causes switch S 1 to change to position b, coupling supply E3 to the line to supply operating power to equipment at the transmitter via diodes D3 and D1 and the power circuit PE. Current flow in D1 is detected and resets the converter causing S0 to close again ready to initiate a further signal when the time base circuit TB again causes the drive circuit DR to operate switch S1 to position a for another signal cycle. The switching of S1 is delayed a time sufficient to allow sufficient power current to be stored in the power circuit PE. In an alternative system, with the power supply and signalling sources E0 and E1 located at the transmitter Fig. 4 (not shown) the receiver plays a purely passive role in the transmission with the duration of both power and signal supply controlled at the transmitter. Similar systems are described using a single source E, Figs. 5 and 7 (not shown), connected by a double pole change over switch to the line at the battery end to provide change in polarity for signalling, and with a rectifier bridge provided to supply a constant polarity to the power equipment and the signalling detected and/or controlled by using the LED of a light coupling unit as one of the bridge arms.

Patent GB-681900-A (GB)
Title: Improvements in or relating to the manufacture of derivatives of substituted cysteines
IPC: C07D277/36
Filed: 1949-03-30
Abstract: The invention comprises compounds of the general formula <FORM:0681900/IV (b)/1> where R3 and R4 are alike or different and are hydrogen or alkyl or aryl radicals but not both R3 and R4 are hydrogen, and R5 and R6 are alike or different and are hydrogen or hydrocarbon groups or groups containing at least one carboxyl radical or functional derivative of a carboxyl group, at least one of the groups R5 and R6 being a group containing at least one carboxyl radical or a functional derivative of a carboxyl grouping.  Such compounds are prepared by a process wherein a compound of the general formula <FORM:0681900/IV (b)/2> (which may be obtained by the process of Specification 681,808) is reduced, thereby replacing the CS group by -CH2-, preferably after S-alkylation, and then cleaved by methods known to be capable of cleaving thiazolidines, to give the desired product.  The alkylation may be effected by reaction with alkyl halide or sulphate.  If R5 and/or R6 contain free carboxyl groups, the alkylated product may be esterified by reaction with diazomethane.  The reduction may be effected by amalgamated aluminium in the presence of water.  To effect the cleavage, the reduction product may be treated with aqueous or aqueous-alcoholic mercuric chloride, to give a complex from which the cleaved product is obtained by treatment with hydrogen sulphide.  In examples: (1) 4 - benzylidene - 2 - mercapto - 5 - thiazolone is reacted with glycine to give a compound of formula II where R3=H, R4=Ph, R5=H, and R6=CH2.COOH.  This is methylated and esterified by reaction with diazomethane and reduced with wet amalgamated aluminium to the methyl - 5 - phenyl - thiazolidine - 4 - carbonamidoacetate from which the a - and b -forms are separated.  The a -form is reacted with aqueous mercuric chloride, and the precipitate treated with hydrogen sulphide. Phenylcysteinyl - glycine methyl ester is recovered from the filtrate as hydrochloride.  In further examples the methylation (with dimethyl sulphate) and esterification (with diazomethane) are effected successively.  There are prepared (2) penicillaminylglycine methyl ester (R3=CH3, R4=CH3, R5=H, R6=CH2 COOH or CH2COOCH3); (3) penicillaminylglycylglycine methyl ester (R3 and R4=CH3 R5=H, R6=CH2CONHCH2COOH or CH2 CONHCH2COOCH3).  The product of (2) reacts with acetone (HCl catalyst) to give a thiazolidine of formula <FORM:0681900/IV (b)/3> Specification 602,755 also is referred to.

Filed: 1932-09-14
Abstract: The exudation of mineral jelly from cordite is tested by heating a sample of the cordite in a new test tube half filled and closed by a slotted cork for one hour at 80 DEG  C.  The cork is then removed for one hour to allow condensed liquid to evaporate.  The cork is replaced and the heating continued for another three hours.  The tube is wrapped in cloth and allowed to cool slowly to avoid condensation of nitroglycerine.  The cold tube is inverted, polished with a clean cloth, and tapped to make the cordite fall on the cork.  Visual examination of the closed end of the tube then reveals the extent of the exudation of the mineral jelly.
