Title: Method for production of alkali salts of penicillin
IPC: C07D499/16
Filed: 1949-10-21
Abstract: Alkali metal (including ammonium) salts of penicillin, richer in penicillin G than the starting materials, are manufactured by reacting an impure mixture of organic base salts of penicillins (including those obtained from Aspergillus flavus) with an alkali metal salt of a carboxylic acid (e.g. acetic or propionic acid) in a substantially inert solvent medium, comprising a mixture of substances chosen from at least two of the groups consisting of chlorinated organic liquids, liquid aliphatic ketones and alkanols of 1-8 carbon atoms per molecule, wherein the alkali metal salt of penicillin G is substantially insoluble whilst impurities and other reaction products are soluble therein.  Each of the components of the final solvent mixture may be used as solvent for one of the reactants, that for the organic base salts being advantageously a chlorinated compound of the formula ZCHCl2 (wherein Z represents hydrogen, chlorine or an organic radical which may or may not contain additional chlorine atoms) and that for the alkali metal carboxylate a lower aliphatic alcohol (in some cases desirably containing a small amount of water). Examples describe the interaction of a solution of potassium acetate in n-butanol with: (1) a solution of a triethylamine salt of penicillin in acetone; (2) a solution of N-ethylpiperidine penicillin in sym.-tetrachloroethane; (3) a solution of a triethylamine salt of penicillin in chloroform.  Lists of additional reagents and solvents are given.  Specification 622,988 is referred to.  The Specification as open to inspection under Sect. 91 comprises the use of any organic solvents capable of dissolving their respective solutes and forming on admixture a single liquid phase in which the alkali metal salt of penicillin (which is not necessarily enriched in penicillin G) is substantially insoluble and the other components of the reaction system soluble. Additional examples describe the interaction of: (a) a solution of a triethylamine salt of penicillin in chloroform and a solution of sodium propionate in methanol, or (b) of ammonium acetate in isopropanol; (c) a solution of the triethylamine salt of penicillin G in chloroform and a solution of rubidium acetate in n-butanol. Alkali metal salts of formic, benzoic, oxalic, malonic, succinic and salicylic acids are specified as additional reagents.  This subject-matter does not appear in the Specification as accepted.

IPC: B23Q35/32
Filed: 1961-07-27
Abstract: 924,308. Electric copying machines. BLACKBURN AIRCRAFT Ltd. Sept. 18, 1961 [July 27, 1961], No. 27328/61. Class 38 (6). The stylus A of a template-following copying machine is supported for both axial and angular movement by a spherical bearing S; and through a ball and cone coupling, Fig. 2 (not shown), rocks a pivoted lever B. Movement of lever B moves a T-shaped contact plate G through a push-rod E. Plate G is pivoted at H and restrained by a tension spring M which urges the stylus A outwards. Plate G carries 6 contacts which co-operate with contacts on a further spring-loaded plate J carried by a pivot K at right-angles to pivot H. The contacts 1 close initially on outward movement of the stylus, governing movement of the cutter into the workpiece, and the contacts 2 close on angular movement of the stylus causing rocking of the lever B to control the cutter to move both inwards and sideways. Axial inwards displacement of the stylus further displaces the lever B to close the contacts 3 and move the cutter sideways, and still further displacement of lever B on angular movement of the stylus closes contacts 4 to move the cutter both sideways and outwards, with further inwards axial movement of the stylus causing contacts 5 to close and move the cutter outwards. Any further axial movement of the stylus closes contacts 6 to stop further movement of the cutter.

Title: Electric switching apparatus particularly an automatic line sectionalizer
IPC: H01H75/04
Filed: 1962-07-18
Abstract: 967,523. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION' July 18, 1962 [Sept. 19, 1961], No. 27599/62. Heading H2B. In a circuit-breaker, such as an automatic line sectionalizer or an automatic-reclosing circuit-breaker, having means to cause tripping or final tripping on the occurrence of a number of overload conditions, an electric impulse responsive means may move a motion transmitting device between a counting device and a trip member to reduce the number of conditions necessary to produce tripping or final tripping. In a gas-filled line sectionalizer, e.g. that of Specification 967,522, the energization of an electromagnet 37, Fig. 1, on the occurrence of an overload condition, lifts an armature 52 and rod 54 to turn a lever 55, Fig. 2, against the bias of an adjustable current setting spring 68, and so raise a pawl 36. When the overload condition ceases, for example on the opening of a series-connected automatic-reclosing circuit-breaker, the spring 68 restores the lever 55 and the pawl 36 engages a tooth 46 on a ratchet wheel 33 to turn the wheel one step. A spring 48 restores the wheel 33 under the action of a mechanical time delay (not shown) but should further overload conditions arise in quick succession, the wheel 33 is stopped until a projection 47 engages a pin 75 on a trip bar 74 and moves the trip bar to trip the circuit-breaker in the manner described in Specification 967,522. If it is desired to reduce the number of steps to produce tripping, an impulse is applied to an electromagnetic device 38 similar to that of Specification 958,332 to pull down an armature 111 into the position shown to interpose a spacer 120 between the pin 75 and the projection 47. Specification 949,898 also is referred to.

Title: Key Material Generator for Cryptographic Equipment
Inventor: MO IVAR
IPC: H04L9/36
Filed: 1967-06-16
Abstract: 1,178,026. Counters. INTERNATIONAL STANDARD ELECTRIC CORP. 16 June, 1967 [17 June, 1966], No. 27790/67. Heading G4D. [Also in Division H4] A cipher pulse generator includes feed-back shift registers in which each feed-back signal is obtained by combining the outputs of a number of stages of the register. The registers' outputs feed a modulo-2 adder which provides the cipher signal. In the system described teleprinter signals are ciphered. The cipher generators at both transmitter and receiver comprises two feedback registers, REG. I and REG. II, the feedback signals being selected by plugboards. The cipher signal is stored in a register REG. Z. Each clear character from the teleprinter is read in to a first shift register, REG. X, which includes a feed-back loop and modulo-2 adders. A number P of shift pulses is now applied to REG. X, determined by a counter which is counted down to zero from P by clock pulses, P being derived by modulo-2 addition of the outputs of selected stages of REG. I and REG. II. The content of REG. X when shifting is ended is a first -ciphered signal which is modulo-2 added to the cipher signal from REG. Z and the resulting second-ciphered signal is returned to REG. X from which it is read out to a store prior to transmission. At the receiver the inverse process takes place, the receiver register REG. X being stepped backward by P steps to provide the deciphered signal. To ensure that registers REG. I and REG. II at the transmitter and receiver start from the same position a synchronizing sequence of six characters precedes the clear characters. If the cipher signals are used in a telex system signals such as " All Space " or " Figure Shift D " would cause undesired operations. It is therefore arranged that any " Figure Shift," or " All Space " signal cannot appear in the transmitted text. The clear text signal stored in REG. X (which is never All Space because this is not used) is inspected prior to stepping the register. If the signal is Figure Shift it is replaced by Carriage Return, and if it is Carriage Return it is replaced by Line Feed. The signal now stored undergoes the first and second ciphering processes and the result is inspected. If it is either All Space or Figure Shift the second ciphering is repeated so that the signal is replaced by the original firstciphered signal. At the receiver the signal undergoes a second-deciphering process corresponding to the second ciphering. If the result is All Space or Figure Shift the signal is seconddeciphered again. The second-deciphered signal is now first-deciphered and the result checked. It it is Carriage Return it is replaced by Figure Shift. If it is Line Feed and is followed by another Line Feed one of these is replaced by Carriage Return. The above description also applied if Line Feed is read for Carriage Return and vice versa. Reference has been directed by the Comptroller to Specification 1,120,032.
