Title: Improvements in or relating to code selectors for selective calling systems
IPC: H04W88/02
Filed: 1959-10-05
Abstract: 936,298. Electric selective signalling systems. GENERAL ELECTRIC CO. Oct. 5, 1959 [Oct. 6, 1958; Nov. 26, 1958], No. 33647/59. Class 40 (1). In a device for recognizing a particular sequence of electric pulses for use for example in a hospital paging system, the first pulse received starts a local clock-pulse generator 4, 5, 6, Fig. 1, which sequentially advances a ring counter ABCD in synchronism with the remaining bits, and the stages of the counter are so connected to two gates 14, 13, which respectively receive the input bits in true and inverted form, that when the particular sequence of bits arrives which the gates are arranged to recognize a gate 9 is not inhibited and the going-on of the D stage of the counter sounds an alarm 10.

Title: Improvement in or relating to electronic timers
IPC: H03K3/352
Filed: 1966-07-26
Abstract: 1,087,678. Transistor line delay switches. G. V. CONTROLS Inc. July 26, 1966 [July 28, 1965], No. 33648/66. Heading H3T. A time delay circuit comprises a bridge having a pair of ratio arms 14 and 11, 13 and a pair of timing arms 22, 21, a base emitter path of a transistor T 1  connected between the junction of the ratio arms and the junction of the timing arms and the transistor and an electronic switch T 3  connected in series across the other diagonal of the bridge. In operation of the circuit shown, upon making switch S, capacitor 21 charges through resistor 22 until its potential at the base of T 1  exceeds the bias at its emitter, whereupon the transistor commences to conduct. The voltage change at its collector is amplified by T 1  to render T 3 , conducting so that regenerative action rapidly switches on the transistors. The voltage change at the emitter of T 3  renders a thyristor 40 conductive to energize the load connected at 0. The capacitor rapidly discharges through the base-emitter path of T 1  in series with T 3  and also through the thyristor via diode 36. Diode 31 protects T 1  against excessive reverse voltage and diode 32 ensures a small initial charge at the commencement of timing period. In Fig. 4 (not shown), the functions of the emitter resistor 11 are effected by separate resistors (5 and 19) and oppositely poled diodes are connected across the capacitor to ensure discharge to zero voltage. In addition, resistor 16 may be shunted by a thermistor to compensate for variation in transistor leakage current.

Title: A process for preparing epoxy esters
IPC: C07D303/16
Filed: 1954-11-23
Abstract: An epoxy ester of a carboxylic acid and a monohydric epoxy alcohol is prepared by heating the carboxylic acid with at least two equivalent amounts (equivalent amount signifying equivalence of epoxy groups and carboxyl groups) of a halogen hydracid ester of a monohydric epoxy alcohol in the presence, as a catalyst, of a tertiary amine or a quaternary salt or a mixture thereof. Suitable acids are the aliphatic, cycloaliphatic, aromatic, mixed aromatic-aliphatic and heterocyclic acids and either saturated or unsaturated acids may be used.  The acids may contain substituents, e.g. alkoxy or ester groups, which do not interfere with the reaction.  Preferred acids are those containing less than 20 carbon atoms, e.g. butyric, propionic, methacrylic, crotonic, adipic, succinic, benzoic and cyclohexane carboxylic acids.  The epoxy ester reactants are preferably of the formula <FORM:0763559/IV(b)/1> wherein R1, R2 and R3 represent hydrogen atoms or hydrocarbon radicals, the latter preferably being aliphatic radicals of not more than 10 carbon atoms. The catalyst may be any tertiary amine but the trialkylamines and amines the pH of whose aqueous solutions are less than 10, are preferred.  When the catalyst is a quaternary salt it preferably has the formula <FORM:0763559/IV(b)/2> wherein Y is a nitrogen, phosphorus or arsenic atom, X is an anion of an inorganic acid and R1 R2, R3 and R4 are hydrocarbon radicals, quaternary ammonium salts being especially preferred.  It is advantageous to use between 4 and 12 equivalent amounts of the epoxy halogen ester and the quantity of catalyst preferably lies between 0.01 and 5 per cent by weight of the acid.  Organic liquid diluents and/or solvents may be added and if one or both of the reactants contain unsaturated bonds a polymerization inhibitor may be added, preferably in an amount between about 0.1 and 5 per cent by weight of the unsaturated reactant(s).  Suitable reaction temperatures are between 50 DEG  and 150 DEG  C.  In examples: (i) benzoic acid (1 mol.), epichlorohydrin (7.5 mols.) and benzyltrimethyl ammonium chloride are refluxed together and the reaction product distilled to give glycidyl benzoate and, as a by-product, glycerol dichlorohydrin; (ii) glycidyl crotonate, di-glycidyl adipate, glycidyl methacrylate and diglycidyl succinate are prepared from epichlorohydrin and the appropriate acid using the same catalyst as in (i); glycidyl benzoate and glycidyl cyclohexane carboxylate are similarly prepared using tetrabutylammonium chloride as catalyst; and glycidyl benzoate is prepared using tributylamine. The use of triethylamine, tricyclohexylamine and pyridine as catalysts and of phenyl-alpha-naphthylamine as a polymerization inhibitor is also referred to.

Title: Preparation of halide addition products, polymers, and oxides of rubber
IPC: C08C19/10
Filed: 1927-12-16
Abstract: 285,071. Goodyear Tire & Rubber Co., (Assignees of Bruson, H. A.). Feb. 11, 1927, [Convention date]. Indiarubber, preparation of.-Rubber is heated with metallic halides of which the positive element possesses secondary valencies, such as tin tetrachloride, antimony pentachloride, titanium tetrachloride, ferric chloride, boron trichloride. to form addition products which contain a plurality of hydrocarbon molecules linked together. The metallic salt may be split off, leaving a white powdery material believed to be a polymer of rubber. The material when made in an inert atmosphere is benzol-soluble, but is partly insoluble if air or oxygen is admitted during the reaction. In an example, a solution of rubber is treated with stannic chloride and allowed to stand in the presence or absence of air. At room temperature the reaction is complete in 24 hours; heat accelerates it. The addition product may be obtained by evaporating the solvent under vacuum, or the polymer mav be precipitated, for example with alcohol. Both the addition product and the polymer absorb oxygen from the, air. After melting, brittle resinous substances resembling shellac are obtained on cooling. The addition products may also be made by milling a solution of the salt into solid rubber.

Title: Improvements in and relating to the synchronisation of clocks

Abstract: 192,879. Hubbard, W. S., Parsons, I. H., and Ball, A. E. J. Dec. 20, 1921. Addition to 167,060. Synchronizing. - In electric clocks having a leaf spring, attached to the pendulum to which is given a losing rate which is controlled by an electromagnet having a moving armature with a pivoted rack as described in the parent Specification and Specification 178,248, the pendulum, when uncontrolled, is adjusted to as nearly correct time as possible and the controlling-devices are arranged to operate so as to correct the pendulum whether it gains or loses. In the arrangement shown in Fig. 1, if the rate of the pendulum D' has increased, the leaf spring B will engage the rack A' of the electromagnet after the pendulum has begun to swing from left to right. The bar C, which is pivoted at C<1> to the fitment D and carries the leaf spring, will be tilted and cause the arm F to move angularly, to cause it to engage a rack G. The arm F, as the pendulum continues its swing, approaches the perpendicular position and depresses the pressure rack G against its spring G<2> or equivalent, and after it passes the perpendicular the pressure rack G gives back its energy to the arm less the amount due to the friction accompanying the action. The same process occurs on the return swing, and the arm F leaves t'he pressure rack G. If the rate of the pendulum has decreased, then the action of the leaf spring B is the same as that described in Specification 178,248, and the depending arm F does not operate. Fig. 4 shows an arrangement where the depending arm F is pivoted to the horizontal bar, and in this case the slowing effect of the engagement between the pressure rack G and the arm F is caused by the work of depressing the rack on the inward swing of the pendulum and on the outward swing by prolonging the swing of the pendulum.
