Title: Improvements in or relating to switches for use, for instance, in automatic telephone systems
IPC: H01H67/06
Filed: 1938-10-07
Abstract: 521,144. Automatic exchange switches. STANDARD TELEPHONES & CABLES, Ltd. Oct. 7, 1938, No. 29132. Convention date, Nov. 10; 1937. [Class 40 (iv)] A selective switch for an automatic exchange system comprises a number of contact sets similar to those used on relays, one member of each co-operating pair of contacts being carried by a vertical multiple strip corresponding 'to a particular outlet and the other being carried by a horizontal feed strip. The latter strips are. removable individually. The actual contacts are of noble metal and may be of the forms shown in Figs. 5 and 10. The switches described employ permutation bars, Figs. 1 and 6 and Fig. 12 (not shown), a travelling carriage, Fig. 4 (not shown), and a rotary drum with helically arranged operating pins, Fig. 15, respectively as the selecting means. In Figs. 1 and 2 each outlet comprises five multiple strips 1 and these are provided with projections which are bent into a single plane as shown at E, Fig. 3, to provide the lower members 3 of the oorresponding contact pairs. The other members 6 are in the form of teeth on a comb the back strip of which is mounted in an insulating block 7. Levers 10 are pivoted on a supporting member 107 and when slots in the permutation bars 11 which move perpendicularly to the plane of the paper are aligned under the levers, a spring 105 rotates them so that the contact operating fingers 104 close the five contacts of the selected outlet. Fig. 6 shows a similar arrangement in which only the test contacts are closed by the finger 40 when the shoe is lowered into the slots of the permutation bars 42, a member 43 being brought at the same time between an operating member 45 common to all the outlets and a rod 44 individual to the outlet concerned. If the outlet is to be seized the switch is stopped and a pawl 47 is moved clear of the member 45 which operates the remaining contact pairs of the outlet. Fig. 12 (not shown) illustrates an arrangement which is similar in principle through it differs in detail. In a modification, Fig. 4 (not shown), the contacts are actuated in turn by a roller on a carriage which is driven to-and-fro along a shaft with a right and left handed worm thread. In another modification, Fig. 15, the contacts are actuated in turn by helically arranged studs 86 on . a rotary drum. The arrangement is such that the drum shaft has a periodical axial movement so that different lines are tested during successive revolutions. In this case the contacts associated with the outlet multiple are the movable ones and feed strips are carried by rods 83 separate from the outlet multiple assembly. Only the test contacts are operated by the drum, a member 91 individual to the set of which the test contact is operated being brought at the same time into engagement with a common operating member 90 which closes the remaining contacts if the switch is stopped in this position.

Title: Improvements in a process of and apparatus for making respirable artificial leather
IPC: D06N3/00
Filed: 1936-10-30
Abstract: 484,007. Agglutinated fibrous webs ; coated fabrics. TUFIDE PRODUCTS CORPORATION. Oct. 30, 1936, No. 29577. Convention date, Oct. 30, 1935. [Class 140] Respirable artificial leather is made by forming a dry, loosely fluffed layer of vegetable fibres, uniformly impregnating the layer with a binder and compacting the impregnated layer into a sheet by successive compression steps. The fibres may be cotton, linen, hennequin, sisal, hemp or wood pulp for example, sulphite, bleached sulphite, soda, or sulphate pulp or old rope or rag pulp. The preferred binder is rubber latex to which glue, ammonia, a volatile organic liquid, and formaldehyde may be added. Fish, hide, casein, blood or egg albumin glues may be used. The organic liquid contains alcohol and preferably consists of a mixture of ethyl and methyl alcohols, acetone, ethyl acetate and gasoline. The alcohol and formaldehyde are introduced into the latex-glue mixture immediately prior to spraying. The fibres are shredded in apparatus A comprising a drum 6 rotating in a housing 2, teeth 3, 8 being arranged on the inner surface of the housing and on the surface of the drum in staggered relationship. The thickness of the fibrous web discharged from the shredder is regulated by an adjustable inclined gate 17. The fibres are carried on an endless conveyer C, preferably a Fourdrinier wire, carried by drums 26, 27, 28 and passing through a cleaning liquid in a tank 32, under reciprocating spray nozzles 55. A second Fourdrinier wire 33 co-operating with the conveyer C passing over rolls 34, 35, 36 and through a cleaning liquid in a tank 41 serves to felt the fibres. It may be replaced by an absorbent belt or roller. The web is further compressed between adjustable rolls 75, 76 and surfacing material such as wood flour or ground fibres is dusted on to the partially dried web by cylinders 87 having internal agitators 90 which force the material through screened openings 88. The web is then passed on a chain conveyer 96 through a drying tunnel 104, heated electrically by coils I and evacuated by a pump 106. Volatile materials may be recovered in a condenser 107. Sets of adjustable rolls 108, 109 further compress the web, which is finally dried in a festoon drier K and calendered or embossed by rolls 125, 126, 127. The product may contain from 35 per cent to 80 per cent, preferably 50-65 per cent of fibre, and may be from “" to ¢" thick. It is suitable for wall and floor coverings and inner soles for footwear.

Abstract: 1525295 Cleaning the interior of hollow vessels IMPERIAL CHEMICAL INDUSTRY Ltd 15 July 1976 [15 July 1975 25 June 1976] 29647/75 and 26514/76 Heading A4F Apparatus for cleaning the interior of vessels such as chemical reactors 12 comprises a central support I rotatable or oscillatable e.g. by pneumatic unit 3 about its longitudinal axis, at least three arms 4 each having a spray nozzle 5 to emit a jet which, at least in a plane normal to the axis, is along the line of the arm, the arms being spaced around the longitudinal axis, preferably equiangularly, so that reaction forces from jets of cleaning liquid ejected from the nozzles are balanced in a direction transverse to the longitudinal axis, means 9, 10 to conduct cleaning liquid such as water or water mixed with steam and air to the nozzles 5, and means, such as pneumatic unit 8 coupled to a central worm (not shown) and worm-wheels 6, to rotate each arm 4 into limit positions (full lines of position A and dashed lines of position B in Fig. 2), respectively trailing and forward of a plane normal to the longitudinal axis, and into retainable positions therebetween (dashed lines of position A and full lines of position B in Fig. 2). The support 1 may be mounted on a steel column 2 as shown or on a hoist (13) as in Fig. 3 (not shown). The arms 4 may have different and/or adjustable lengths and each may have either two nozzles 5 or a nozzle providing two vertically-spaced jets, the jets issuing parallel to the length of the associated arm. Alternatively the two jets may diverge from one another and/or issue at an acute angle to the arm. The limit positions of the arms 4 are desirably parallel to the longitudinal axis or, if not, within 30 degrees of parallel. To clean a vessel 12 of the shape shown in Fig. 2 the apparatus is lowered into the vessel with the arms 4 in the trailing limit position (position A, full lines). Then with the apparatus as a whole stationary the support 1 is set rotating or oscillating whilst the arms are rotated, e.g. stepwise, outwards by the worm/worm-wheels 6 until they are normal to the longitudinal axis (dashed lines, position A). This cleans the top dome 13 of the vessel. Rotation of the arms 4 by the worm/worm-wheels 6 is then stopped and the cylindrical wall 14 of the vessel is cleaned by simultaneously rotating or oscillating the support 1 and lowering the apparatus as a whole (until position B, full lines is reached). Then with the apparatus as a whole held stationary again the arms 4 are further rotated by worm/worm-wheels 6 until the forward limit position (position B, dashed lines) is reached while the support 1 is oscillated or rotated thereby cleaning the domed bottom 15 of the vessel.

Abstract: 662,840. Automatic steering control systems. BENDIX AVIATION CORPORATION. Oct. 4, 1946 [Nov. 26, 1945], No. 29672/46. Class 38 (iv). In an automatic steering system for a craft signals from a flux valve compass are applied to the stator of an inductive transmitter, the rotor of which is electrically connected to an actuating device for both the rudder of the craft and the rotor of the inductive transmitter. In the figure deviations from course of a craft are detected by a flux valve compass 10, which may be stabilized by an artificial horizon gyro (not shown), the primary windings of which are supplied from a source 17, 18 of D.C. pulsating at the frequency of the craft's source of A.C., 22, the secondary windings supplying to the stator 30 of an inductive transmitter a signal, at the frequency of the craft's source of A.C., dependent in magnitude and phase on the magnitude and sense of course deviation. The output of rotor 31 of the inductive transmitter, amplified by amplifiers 34 and 35, controls one phase 39 of a two-phase induction motor 40 controlling rudder 45 of the craft, rotor 31, and, normally, rotor 51 of a second inductive transmitter 49. Rotor 51 is supplied from the crafts' source of A.C. and the output from stator 50 is applied as input to amplifier 35 in opposition to the output of amplifier 34 so that the extent of rudder deflection is dependent on the magnitude of course deviation. The output from the stator 69 of a third inductive transmitter 68, the rotor 70 of which is supplied from the crafts' source of A.C. and coupled to a rate-of-turn gyro 62, is also applied as input to amplifier 35 to improve stability. Inductive transmitter 49 may be uncoupled by opening switch 56 to release magnetic clutch 54 whereupon rotor 51 is set by springs 58, 59 to a null position in readiness for further operation. Rudder 45 may be released, for manual operation, by clutch 47 which may be of the type described in Specification 593,319, [Group XXIV]. Specification 662,831 is referred to.
