Title: Apparatus for distant electrical transmission for indicating purposes
IPC: G08C19/24
Filed: 1927-02-04
Abstract: 269,855. Schneider et Cie. April 23, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Synchronous movements and synchronism indicators.-In an electric signalling system wherein orders transmitted according to the position of a brush 13 on a rotating contact maker 7 are reproduced by a fixed discharge lamp 25 located behind a synchronously rotated disc 23 having a signal aperture 24 synchronism is obtained at the transmitter and receiver by synchronizing impulses which are sent over a fixed brush 12 and connected in series with cam-operated contacts 17, 18. The cam 16 rotates at a speed which differs from that of the commutator 7 so that the impulses are transmitted at a relatively slow rate to produce an intermittent luminous indication at the receiver. Synchronism is established when the reference mark 27 on a graduated scale is moved into coincidence with the luminous index. Alternatively the scale may be fixed and the phase may be adjusted by displacing the disc relatively to its driving shaft by the apparatus shown in Figs. 2 and 2a. The disc 23 is mounted on a shaft 23 upon which is loosely mounted a pinion 22 driven by the motor 2, Fig. 1. The pinion 22 has two toothed cylinders 29, 30, the teeth of which are relatively disposed as shown in Fig. 2<a>. Normally, the shaft 28 is driven by a cotter 31 which engages the teeth of the cylinder 29, but when the phase is to be adjusted, the cotter 31 is pressed into engagement with the cylinder 30 by a spring-controtled push 34 and then released. This operation displaces the disc 23 through a distance of a step relatively to the driving-shaft and is repeated to bring the intermittent luminous index into coincidence with a fixed zero line 27. In a modification, the phase may be adjusted by swinging the stator of the motor 2. In a modification a continuous current motor 63, Fig. 7, at the receiver operates through a friction drive 66, 67, the discs 23, 23<1> which co-operate with the discharge lamps 25, 25<1> respectively. The speed of the discs is adjusted to that of the transmitter by a handle 69, which is adapted to vary the position of the wheel 66 on the friction disc until the luminous image produced by the aperture 24<1> is stationary. Phase relations are then adjusted by the handle 70 of a differential mechanism 71 until the synchronism indicator is coincident with the fixed zero mark 27.

Title: Honeycomb structures
IPC: C04B35/52
Filed: 1972-01-25
Abstract: 1387143 Honeycomb structures of carbon NIPPON TOKI KK 25 Jan 1972 [18 May 1971] 3376/72 Heading ClA A honeycomb structure, i.e. a series of linked juxtaposed hollow bodies of substantially the same shape, made of carbon is formed by coating mandrels which are tubes or rods having the desired cross-sectional shape with a material which is carbonizable when heated at a sufficient temperature in a non-oxidizing environment, said tubes being carbonizable under the same conditions or said tubes or rods being removable from the product obtained by drying the coated mandrels without damage to the shaped body formed, either by sample withdrawal or dissolution, arranging the coated mandrels so they are in contact with one another and together form the desired honeycomb block, drying the coated mandrels and if appropriate removing the initial mandrel tube or rod by withdrawal or dissolution, and finally heating the dried product to carbonize it and form the desired honeycomb. The removable mandrel may be metallic or made of a thermoplastics material which latter is conveniently removed by dissolution. The honeycomb formed may be strengthened by impregnating the honeycomb with thermosetting resin. If desired, the resin impregnated body may be subsequently carbonized. The non-oxidizing environment used during the carbonizing step may be powdered carbon. The cells of the honeycomb may be of different sizes, and they may be made of amorphous carbon, active carbon, graphite or glassy carbon. The walls of the cells may be composed of two different types of carbon, one of which carbons may be formed by deposition on the other. The cells of the honeycomb may be circular, elliptical, triangular or polygonal. The carbonizable mandrels may be of paper or thermosetting resin and the materials used for coating the mandrels may contain carbon black, graphite powder, coke powder coal powder, and organic materials for example sugar, phenol-formaldehyde resin, powdered nut shells and staple artificial or natural fibres. All these coating materials have to be mixed with binders to provide green mouldings of sufficient strength. Suitable binders and solvents are listed. The carbon honeycombs may be subsequently activated to give an active carbon of stated surface area.

Title: Improvements in or relating to circular knitting machines and in methods of feeding elastic threads therein
IPC: D04B1/18
Filed: 1941-03-12
Abstract: 540,964. Knitting. SCOTT & WILLIAMS, Inc. March 12, 1941, No. 3388. Convention date, April 2, 1940. [Class 74 (ii)] Relates to means for and a method of feeding bare or covered rubber thread to a rib knitting- machine and knitting it under uniform stretch. The mechanism first removes all tension from the rubber thread and then presents it in an unstretched condition to a positive feeding means which stretches it uniformly. The thread R is pulled off a supply 100 by a yarn furnisher consisting of a small electric motor 110 geared to two yarn advancing spindles 115, 116 with circumferential grooves 119. The rubber thread is wrapped around the spindles in loops, embracing both spindles and progresses from one groove to another towards the free ends of the spindles, where it drops off. This process slightly kinks the thread R, which is straightened by a feeler arm 120 forming part of a multipoint mercury switch 125. The contacts are so located that as the feeler arm moves, the number of points in contact with the mercury is varied to control the speed of the motor 110. From the eye 130 in the end of the arm 120 the thread R passes to a feeding device consisting of a cone 140 positively driven from the dial driving gear 36 through gears 146, 147. The gearing relation is such that the linear speed of the thread passing between the cone 140 and its associated pressure roll 141 is less than the amount drawn by the needles, which results in the thread being uniformly stretched. A cam 139 is used to put pressure on the fabric opposite the knocking-over point to pull the rubber stitches away from the needles.

Title: Improvements in photographic developing processes more especially for use with printing surfaces
IPC: G03C5/315
Filed: 1927-02-07
Abstract: 265,630. Soc. de Photochimie Elka. Feb. 8, 1926, [Convention date]. Etching.-The development of silver bromide layers to produce differential hardening, more especially for the production of photo-mechanical printing-surfaces, is effected by partly developing with a tanning developer and completing the development with a non-tanning developer. The tanning of the exposed parts is thereby accelerated without any hardening of the unexposcd parts. After transfer to a metal plate and hot water treatment the bare metal, if necessary, can be completely cleaned by rubbing with a pad impregnated with a slightly abrasive mixture. After inking the hardened gelatine can be removed by acid and the plate used for litho transfers, or engraved for use as a typographic plate. Alternatively, and for line or half-tone photogravure, the plate can be etched, as with perchloride or iron. In another process the bare metal after washing out the soft gelatine, can be metallized as with silver. The silver coating can be produced from the silver in the picture layer, processes of this being described. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-When metallizing the bare metal of a plate after washing out the soft gelatine, leaving a hardened gelatine picture thereon, the coating metal is preferably one widely separated in the scale of electrolytic tensions. The effect of a silver reserve on a zinc plate in subsequent etching is also described. Also in the preparation of relief plates, the plate having the gelatine relief thereon, which is fully hardened, as by formol, is coated with silver in the bare parts, inked up, the gelatine removed, the ink coated with resin and warmed, and the plate etched. The etching can be deep owing to the silver reserve. Further re-etching can be effected by cleaning the plate, covering the surface of the lines with a removable coating, removing the removable coating with the ink from the metallized parts, and re-metallizing these parts preliminarily to a further etching process. This subjectmatter does not appear in the Specification as accepted.

Filed: 1949-02-09
Abstract: 657,364. Automatic exchange switches. GENERAL ELECTRIC CO., Ltd., and DEWAR, G. Feb. 9, 1949, No. 3487. [Class 40 (iv)] In a contact interrupter assembly for a stepby-step switch the two flat springs carrying the contacts are of unequal length and the motion of one of them is limited by two fixed stops. As shown, the longer of the springs 2 carries an extension 3 acted upon by an insulator 4 on the switch armature 5, and a contact 6 which presses against the other contact 7 carried by the shorter spring 8. Two further springs 9 and 10 constitute the stops, spring 8 being tensioned to rest against spring 10, but spring 2 having a higher bending moment presses spring 8 against spring 9. During operation contacts 6 and 7 remain in contact while spring 8 moves from one stop to the other, but as the springs 8 and 2 have different lengths a rubbing action takes place between the contacts tending to clean them. The assembly comprising the four springs, three insulators 1, and plates 12, 13 is held together by screw 14 and may be rocked about the centre of plate 13 to permit accurate adjustment of the end 3 of spring 2 relative to the insulator 4. The assembly is fixed in position on the frame 15 of the switch by tightening screws 16, 17.
