Title: Improvements in and relating to the manufacture of rennet
IPC: C12N9/64
Filed: 1940-03-28
Abstract: 539,941. Rennet. BENGER'S FOOD, Ltd., . THORNLEY, B. D., and HILTON, S. March 28, 1940, No. 5567. [Class 2 (iii)] A moist rennet preparation such as that produced according to Specification 532,458 is dried by admixture with an efflorescent salt. The efflorescence of the salt may be assisted by reduced pressure and warmth and, if desired, a desiccating agent may also be employed. Suitable salts are sodium and magnesium sulphates and, when the rennet preparation is sufficiently acid, di-sodium hydrogen phosphate may be used ; this has the effect of bringing the pH to the preferable value of about 7. Di-potassium hydrogen phosphate may be used together with sodium sulphate, in which case the dry preparation should be dissolved in a slightly acid or neutral buffer solution before use, though it may be added direct to the milk to be treated. In examples the wet rennet preparation is admixed with (1) anhydrous sodium sulphate ; (2) anhydrous sodium sulphate and di-potassium phosphate ; (3) hydrated sodium sulphate ; (4) hydrated sodium sulphate and di-potassium phosphate, the mixture being placed over calcium chloride in a vacuum desiccator ; (5) magnesium sulphate (MgSO  4 2H 2 O) at pH 3.4; magnesium sulphate (MgSO  4 7H  2 O ) at pH 3.2 in vacuum over calcium chloride. Specification 188,660, [Class 2 (iii)], is referred to.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1931-02-23
Abstract: 371,525. Automatic exchange systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Feb. 23, 1931, No. 5681. Convention date, Feb. 22, 1930. [Class 40 (iv).] A common control circuit for a group of conversational switches is normally in operative association with an idle one of of the switches, and the switches remain in the position occupied when last used until thev are next taken for use by the control circuit. As described, a common control circuit for uni-directional group selectors is connected to an idle selector by a preselecting switch and comprises a register switch responding to incoming impulses, and an auxiliary switch responding to impulses sent by the group selector when it passes last contacts of groups, group selection being determined by a relay which operates when the register and auxiliary switches are in corresponding positions, said relay being also used to control the hunting movement. When first group selector IGW seizes group selector IIGW, relay V2 in the control circuit operates over the test wiper since P is energized over wiper a1 of the pre-selector a1 .. a8. The test circuit includes off-normal contacts of the register and auxiliary switches De, Dh. Relay C2 pulls up and A repeats impulses to register magnet De which holds V2, a circuit for the magnet D of the group selector being also completed over wiper a2, subsequent to the relapse of T1 which was operated by V2 and releases when De has taken two steps. When the group selector reaches last contacts of a group, contact is made at 15w, T2 operates to sent an impulse to magnet Dh of the auxiliary switch and to open the circuit of magnet D which is started off again at contact 41 dh of Dh. When wiper dh reaches a position corresponding to de, T1 operates over resistance Wi6 since V2 holds for a sufficient length of time after cessation of the impulse train. The circuit for D is opened and on the relapse of V2, T1 releases and the group selector hunts for an idle outlet. When an outlet is found T1 again operates, short-circuits P which short-circuits C2 so that C1 pulls up over (i), locks over (ii) and switches through. Release. On the relapse of C2, Dh and De home in succession, and Da hunts under the control of P for the next idle conversational switch. The conversational switch does not restore to normal until a homing circuit over 5w is completed on its next seizure by the preselector.

A solid fuel igniter substantially as described in the parent Specification has the bar type heating element replaced by an element in the form of a wire or strip having lengths or portions transverse to the axis of the air flow tube 1 in which it is mounted. The tube 1 is of ceramic material and has four rows 3-6 of holes through which a heating element 2 is woven. The holes of rows 3 and 5 correspond as do those of rows 4 and 6, the two pairs of rows being staggered along the tube with respect to each other. The element comprises coiled portions 7 and straight portions 8, one half of the element being woven through rows 3 and 5 and the other half through rows 4 and 6 so that the coiled portions lie horizontally across the inside of the tube 1 and the straight portions lie on the outside of the tube. The two ends of the element are led to the inside of the tube 1 via small holes 9 provided therein. The straight portions 8 of the element are covered by segments 10 of ceramic material positioned by protuberances 11 in the holes in the tube 1, and ribs 12 and 13 on the tube 1, the ribs 13 also serving to space the tube 1 from the second air-flow tube surrounding it. If desired, fire cement may be used to cover the portions 8 in place of the ceramic segments. Reference has been directed by the Comptroller to Specification 803,329.

IPC: C08G18/67
Filed: 1960-02-22
Abstract: A process for the production of a polyurethane prepolymer comprises reacting under substantially anhydrous conditions an organic polyfunctional isocyanate or isothiocyanate of the general formula R(NCX)n+1 (where R is a polyvalent organic radical, X is oxygen or sulphur and n is any integer), with an unsaturated organic dihydroxy compound that is a condensation product of a nucleating agent with an alkylene oxide, in such amounts that the ratio of total -(NCX) groups to total hydroxyl groups present in the reaction mixture is greater than 1:1.  The term "nucleating agent" is defined as a dihydroxy or dimercapto compound having in its molecular structure aliphatic unsaturation e.g. butene-2, diol-1:4; butyne-2, diol- -1:4; hexene-3, diol-1:4 and hexyne-3, diol-2:5.  The term "alkylene oxide" is defined as an organic compound containing an epoxy group capable of reacting with the hydrogen atoms of the hydroxyl groups in the nucleating agent e.g. ethylene, propylene or styrene oxide.  Many isocyanates and isothiocyanates are specified. The prepolymers may be converted into (a) synthetic rubbers by heating in the presence of a basic catalyst e.g. sodium methoxide and ethoxide calcium oxide and hydroxide, barium oxide and hydroxide, sodium hydroxide, trimethylamine, N-methyl morpholine, triethylene diamine, triethylamine, tripropylamine, tributylamine, triamylamine, tribenzylamine and dimethyl aniline and (b) plastics which may be foams, by reacting with a compound containing a plurality of active hydrogen atoms. In a modification of the process of the invention, the reaction between the condensation product and the isocyanate or isothiocyanate is effected in the presence of a compound containing a plurality of active hydrogen atoms to produce a plastic which may be a foam. Specified compounds containing a plurality of active hydrogen atoms are ethylene glycol, 1:3-propane diol, 1:4-butane diol, water, ethylene diamine, trimethylene diamine, tetramethylene diamine, m-phenylene diamine, naphthylene diamines, toluene-2:4-diamine, aminobenzyl aniline, amino diphenylamine, 2-aminoethanol, 2-amino-1-naphthol, m-aminophenol, glycollic acid, a -hydroxypropionic acid, aminoacetic acid, and amino benzoic acid. In the examples: (1) to (5) condensation products are made from ethylene oxide and: (1) hexane-3, diol-2:5, (2) hexyne-3, diol-2:5; (3) butene -2, diol-1:4 and (4) and (5) butyne -3, diol-1:4.
