Title: Improvements in or relating to two-directional electric telephony systems
IPC: H04B3/20
Filed: 1938-04-05
Abstract: 501,234. Two - way transmission. SIEMENS & HALSKE AKT.-GES. April 5, 1938; No. 10433. Convention date, April 5, 1937. [Class 40 (iv)] In a two-directional system comprising a two-wire line which branches through forks 3 and 4 to the two sides 1 and 2'of a four-wire system, suppressors S1 and S2 are associated with the side channels in such a manner that when signals are passing along one channel, the suppressor associated with the other channel blocks the latter channel only for signals that are no stronger than the echo signals. The output of an amplifier or amplifier-detector V3 connected to line 1 controls the suppressor 82 and a corresponding amplifier V4 connected to line 2. A steady alternating voltage G of a frequency outside the operating range of frequency of the system is applied to the input of the amplifiers V3 and V4 to ensure that the system remains in a stable rest condition when signalling ceases. The suppressors S1 and S2 may be contacts for making or breaking the respective lines, operated by a polarized relay having two windings energized respectively by the output currents of the amplifiers V3 and V4. The relay may have holding windings so that when signalling ceases the system remains in a stable condition of rest. Alternatively, a non-polarized relay can be used. In the modification shown in Fig. 1a the output of. the amplifier V3 is applied through a transformer 9 to a rectifier circuit and produces a voltage across a resistance W. The amplifier V4 similarly produces an opposing voltage across a resistance W1. The resistances W and W1 are arranged in series with a gas-filled discharge device Gli, a resistance R, and a battery B1. When line 1 is used, the voltage produced across the device Gli is greater than the striking voltage of the device and a current passes through R. The voltage across R is utilized to operate the suppressor S2. When line 2 is used, the voltage across the device Gli is reduced to below the extinguishing voltage and the suppressor is not operated. Specification 430,567 is referred to. Reference has been directed by the Comptroller to Specifications 335,937, [Class 40 (iv)], and 439,752.

Title: Process for the polymerisation of olefinically unsaturated hydrocarbons
IPC: C08F10/00
Filed: 1962-03-19
Abstract: Polymers of olefinically-unsaturated compounds are made by polymerizing one or more of the compounds in the presence of a catalyst comprising a vanadium complex of an aromatic carboxylic acid substituted in the aryl nucleus by one or more OH and/or SH groups and a reducing agent such as an organometallic aluminium compound. The aromatic hydroxy or mercaptocarboxylic acid is preferably substituted in the aryl nucleus by one or more hydrocarbon radicals. The complex is generally prepared by reacting in aqueous medium a vanadyl sulphate with an alkali salt of an aromatic carboxylic acid such as diisopropylsalicylic acid, 3,5-di-tert. butylsalicylic acid, naphthalene-2-hydroxy-3-carboxylic acids, naphthalene-2-hydroxy-1-carboxylic acids substituted by alkyl groups, dialkylmeta or para-hydroxybenzoic acids, dihydroxybenzoic acids and dihydroxynaphthalene carboxylic acids substituted by alkyl groups, and corresponding mercapto-carboxylic acids. Exemplified reducing agents are aluminium isobutyl sesquichloride, aluminium ethyl sesquichloride, aluminium dimethyl chloride, aluminium ethyl dichloride, and aluminium diethyl chloride.  The polymerization is effected in a hydrocarbon or halogenated hydrocarbon diluent.  The catalyst may be preformed or prepared in situ.  Polymers exemplified are copolymers of ethylene and propylene, polybutadiene, a copolymer of ethylene and dicyclopentadiene, a terpolymer of ethylene, propylene, and dodecene, a terpolymer of ethylene, propylene, and di-cyclopentadiene, and a quaterpolymer of ethylene, propylene, dodecene-1, and dicyclopentadiene.  The polymerization may be effected continuously.  The polymers may be vulcanized with conventional recipes.  Specifications 843,160, 856,773, 857,183 and 857,938 are referred to.

Abstract: 105,329. British Westinghouse Electric & Manufacturing Co., (Assignees of Perkins, L. M.). March 13, 1916, [Convention date]. Systems for continuous-current motors only.-In a regenerative control system, a single relay governs the connexion of the motors to the line during regeneration, and operates in accordance with the speed of the motors or their voltage conditions. In the system illustrated in Fig. 1, the motors 3. 4 have fields 5, 6 connected with resistances 23, 24 across an exciter 25. Series-parallel control is obtained by a line switch 20, a series switch 19, and parallel switches 21, 22. The contactors 10, 11, 12, 16, 17, 18 control resistance sections in the ordinary way. The contacts of a relay 26 are connected in series with a battery and the winding 29 of the line switch 20. The winding 27 of the relay is connected to the trolly side of the armature 3 and the earth side of the armature 4, and is therefore connected across one motor in the parallel connexion and across both motors in the series connexion. During regeneration, the relay 26 is lifted when the motor voltage exceeds that of the supply. As the speed diminishes, resistance sections are cut out by the operation of the master controller, and the connexion is changed from parallel to series.
