Title: Improvements in the manufacture and production of ureas from alpha-omega-diaminocarboxylic acids
IPC: C07C273/18
Filed: 1936-02-13
Abstract: Aliphatic a o -diaminocarboxylic acids substituted in the a -amino group are heated with cyanic acid or a cyanate to form the corresponding urea.  If desired, the substituent in the a -amino group, e.g. an acyl residue, is then removed by saponification.  The reaction may be effected in aqueous or aqueous alkaline solution or in the presence of organic solvents; in the latter case it is necessary to acidify the reaction mixture and wash with water.  The products possess therapeutic properties. According to the examples: (1) a -monobenzoylornithin is boiled with aqueous potassium cyanate, and dilute sulphuric acid then added to precipitate a -monobenzoyl - d  - carbamidoornithin; on heating with dilute sulphuric acid for some hours, d  - carbamido - ornithin is obtained; (2) a -monobenzoyl-lysine is treated with potassium cyanate as in (1) and the resulting a  - monobenzoyl - e  - carbamido-lysine then converted by saponification into e  - carbamido-lysine.

Abstract: 524,897. Artificial silk &c. HILL, F. B., and JACKSON, T. Feb. 10, 1939, No. 4407. [Class 2 (ii)] Textile materials having a basis of a cellulose derivative are subjected, in the absence of tension sufficient to stretch them, to the action of a medium comprising a shrinking agent which is a non-associated substance and a small proportion of a carboxylic acid or an ester thereof. The treatment results in increased extensibility or in the case of woven or other fabrics, shrinkage effects are produced. The shrinking agent may be methylene chloride or other halogenated hydrocarbon which is a latent solvent and it may be diluted with an aliphatic or aromatic hydrocarbon e.g. benzine, petrol ether, kerosene, benzene, toluene, or xylene, or with carbon tetrachloride. The additional agent may be an aliphatic or aromatic carboxylic acid or an ester e.g. acetic, formic, glycollic, lactic, succinic, tartaric, or citric acid, or benzoic or salicylic acid, or glycol mono or diacetate, dibutyl tartrate, alkyl or ketonyl phthalates, or the ethyl ether of glycol monoacetate. The additional agent may be present in a proportion of less than one per cent. Filaments, threads, yarns, fabrics, or fibres containing or derived from high tenacity filaments which have been stretched in steam or hot water, may be subjected to the treatment. Preferably the materials are allowed to shrink during the treatment. Staple fibres acquire a crinkle or crimped effect. The materials may be made of cellulose acetate, acetobutyrate, or other ester or methyl, ethyl, benzyl cellulose or other cellulose ether. In an example, dry spun cellulose acetate yarn which has been stretched in wet steam is immersed in hank form in a bath of 65 per cent. methylene chloride and 35 per cent. kerosene containing 2.5 cc./litre of glacial acetic acid, and allowed to shrink freely. It is washed with petroleum ether and dried. Specifications 380,504, 389,823 and 523,425, are referred to.

Title: Improvements in or relating to electrical pulse frequency dividers and the like
Inventor: CLARKE PHILIP BRIAN
IPC: H04J3/04
Filed: 1951-02-28
Abstract: 707,401. Pulse circuits. POSTMASTER GENERAL. Feb. 28, 1951, No. 4936/51. Class 40 (6) In a circuit of the type in which pulses from a master pulse generator are applied via gate circuits to a series of single stroke pulse generators connected in a ring, each pulse generator after having generated a pulse is blocked for a period exceeding one half but less than the period of the ring cycle of operations so that in this way only one pulse circulates in the ring at any given instant. The circuit may be used to generate time spaced trains of pulses for application to pulse modulators as described in Specification 707,384. The Figure shows two blocking oscillator pulse generator stages comprising valves Vl, V2 associated with gating stages V11, V21 forming part of similar stages connected in a ring to which master pulses are applied via lead K1. Gate valve V11 is normally held non-conducting with key K in the position shown by the bias voltage -V3 applied to its control grid circuit. The ring action is started by opening contact K when the grid voltage of valve V11 rises to -V2 so that valve V11 is rendered conducting by the next master pulse on lead K1. The negative pulse at the anode of valve V11 triggers the blocking oscillator stage V1 which generates a positive output pulse at lead p1 the valve VI 1 then being blocked for a time determined by the constants of delay line 14, 15 and resistor 13. The negative pulse at the anode of valve V1 conditions the gate valve V21 so that it is rendered conductive by the next master pulse on lead K1 and thus triggers the next blocking oscilator stage V2 to produce an output pulse at lead p2. This action then continues round the ring pulses being produced sequentially at the output leads p1, p2 &c. The time during which each blocking oscillator stage is blocked after generation of an output pulse is made greater than one half but less than the period of the cyclic operation of the ring thus ensuring that when key K has been restored to its normal position shown only one pulse will circulate round the ring at any instant.
