Title: Automatic impulse transmitters
IPC: H04M1/274
Filed: 1933-12-21
Abstract: 432,211. Impulse transmitters. HIRSCHFELDT, H., 11, Lyndhurst Gardens, Hampstead, London. Dec. 21, 1933, No. 35988. [Class 40 (iv)] In an impulse-transmitter in which a member 9 controlling the transmission of impulses at contacts 17 co-operates with a shaped member 15 representing a particular subscriber's complete number, the member 9 is brought intermittently into engagement with the member 15 instead of gliding continuously over it. In the arrangement shown, the rod 9 is reciprocated by a cam on a rotary shaft 2 which also carries a universally-mounted cam 3 controlling the impulse springs 17, the rod 9 being linked to the cam 3 in such a way that when the rod encounters a projection 14 impulses are transmitted but when a depression 16 is engaged the cam 3 is tilted and no longer engages the springs 17. The impulsing elements, Fig. 1, may be mounted in a block 22, Fig. 5, reciprocated by a clockwork-driven worm 23 controlled by a starting lever 27, the shaft 2 being geared to the worm for rotation during the return movement only by a pinion 29 and a pawl 30 engaging a longitudinal slot 28. The members 15 may be bars of L- or T-section, Fig. 8, provided with teeth 16 which may be bent up as required and are preferably arranged in two staggered rows. The bars may be arranged to form a hollow cylinder, Fig. 9, with the teeth projecting inwardly, the cylinder being rotatable by a handle 34 to bring any desired bar into operative position, this rotation being only possible when the starting lever 27 is at normal. A shoe 35 wide enough to bridge the gaps 16 but dropping into a longer depression when all the impulses have been sent controls a short-circuit around the telephone instruments.

Abstract: 412,189. Junction boxes. PETRIE, D. G., Italian House, Meadow Green, and UNITY HEATING, Ltd., (formerly YOUNG, OSMOND, & YOUNG, Ltd.), Unity Works, both in Welwyn Garden City, Hertfordshire. Dec. 19, 1932, No. 35997. [Class 38 (i).] A tubular electric heater is provided at one end with a junction box formed in two separable parts so as to afford lateral access to the terminals. In the arrangement shown in Fig. 4, the terminals 7 are fixed in an insulating block 9 which is fitted into a collar 2 on the end of the heater tube 1 by a pin-and-slot fastening and held in position by a spring blade 12. One part 15 of the junction box is welded to the inside of collar 2, the other part 16 being removable and formed with a concave end 17 which fits between the block 9 and the collar 2. The two parts are held together by an end cap 22 and form between them when assembled two diametrically-opposite circular apertures 18, one of which is fitted with a flanged closure disc 19, Fig. 7, and the other with an eyelet 20 containing a screwed bushing through which the supply conductors pass. In another construction, the two parts of the junction box are hinged to the collar 2 and in a further construction both are hinged to the cap 22 and are locked in position by a rotary sleeve surrounding their inner ends. In the arrangement shown in Fig. 7, three tubular heaters are connected together electrically and mechanically by bus-bars 30 passing through apertures 18 and forced into direct engagement with the terminals 7 by insulating wedges 33. The bus-bars carry earthing sheaths 32 and the junction-box parts 16 may have earthing terminals 26, Fig. 4. Specification 412,347 is referred to.

Title: Copolyurethanes
Inventor: MCGILLIVRAY ROY
IPC: C08G18/32
Filed: 1959-10-26
Abstract: The invention comprises copolyurethanes containing the structural component <FORM:0913859/IV(a)/1> where X and Y are the same or differing members of the group comprising -O- and -CH2-, R is a member of the group comprising alkylene, arylene, cycloalkylene and alkylarylene and n is an integer, in which a proportion of the dioxy units <FORM:0913859/IV(a)/2> is replaced by other dioxy units which contain at least one basic tertiary nitrogen atom.  Such products are obtained by reacting the diols 1:4-bis (hydroxymethyl)-cyclohexane and 2:5-bis (hydroxymethyl)-tetrahydropyran with a diisocyanate OCN-R-NCO or a corresponding methane R1OCONHRNHCOOR1 or by reacting the bis-chloroformate of the diol with a diamine H2NRNH2, a proportion of diol or bischloroformate being replaced by a similar compound containing a basic tertiary nitrogen substituent.  In examples polymers are formed by reacting 3,31-dimethyldiphenylylene-4,41-diisocyanate with (2) 1:4-bis (hydroxymethyl) cyclohexane and N,N1-bis (2-hydroxyethyl) piperazine; (3) 1,4-bis (hydroxymethyl)-cyclohexane, and N-cyclohexyl-3-azapentan-1:5-diol; (4) 2,5-bis (hydroxymethyl)-1,4-dioxan and N,N1-bis (hydroxyethyl) piperazine. For comparison various diisocyanates are reacted with the non-basic diols alone.  Filamentary materials having an affinity for acid dyes are obtained by melt-spinning the polymers, generally at temperatures below 300 DEG C.

The particle size may be between 50 and 220 microns. The apparatus used for carrying out the process consists of a generator 1, a timing device 3 adapted to operate the generator for a pre-determined period and a work coil 4 to apply the magnetic field. The process may be used to construct double glazing units either with lead spacers or alternatively with plastics spacers.

Abstract: 522,841. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 19, 1938, No. 36937. Convention date, Dec. 20, 1937. [Class 38 (iv)] Electromotive force.- In a voltage regulator operated by a twophase induction motor 1 having two operating windings energized in different phases, one 3 of which is fed through a voltage responsive circuit, the other 2 being in circuit with a constant impedance 6, in order to reduce losses in the second winding the impedance is a choke which has a D.C. saturating winding so controlled that in normal conditions it is unsaturated. Preferably the saturating winding is fed by the rectified current of the voltage responsive winding as shown. A short circuited winding may be arranged on the D.C. winding in view of the A.C. component in the current. The saturation may be adjusted by varying the turns of the winding or shunting it.

Abstract: 1,020,891. Electro-photographic development. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 1, 1962 [Oct. 2, 1961], No. 37074/62. Heading G2H. A charge image on a dielectric material is developed by exposing the material to a vapour which softens and deforms the material in accordance with the charge pattern. In the embodiment shown, a web 10 of dielectric material is fed from a reel 44 past a negative charging station 48 and round part of a photo-conductive drum 50 carrying a charge image formed on its surface by exposure to an original 60 after being positively charged by corona device 52. Another drum 68, the surface of which is kept at a predetermined potential aids the formation of a charge image on the web which is then fed through a developing chamber 16<SP>1</SP> and a fixing chamber 16<SP>11</SP> and on to a reel 46. A lamp 71 removes residual charges from the drum 50. The developing chamber is supplied with material softening vapour from a liquid bath 20 in which a heater 26 is placed. A blast of air from a blower 28 condenses the excess vapour in the fixing chamber and hardens the deformed and softened material. The dielectric material may be polystyrene, polymethyl methacrylate, polyvinylchloride, polyvinylidine, ethylcellulose or styrene coated polyethylene glycol terephthalate. The material softening vapour may be trichlorethylene, acetone, toluene or methylene chloride.

A perforated record card is sensed by means of a pair of air jets in opposing relationship on opposite sides of the card. Air from the first jet normally escapes over the surface of the card so that a low pressure is maintained in a channel connected to that jet. When a perforation lies between the jets, air from the second jet impedes the escape of air from the first jet and creates a back pressure in the channel to operate a sensor such as a fluid amplifier.
