Title: Gas supply apparatus
IPC: G05D16/14
Filed: 1974-07-04
Abstract: 1471872 Fluid-pressure servomotor systems HANSON BDC (CHESTERFIELD) Ltd 4 July 1974 [30 July 1973] 36274/73 Addition to 1408394 Heading G3P The system for supplying gas to consumers through a main 40, described in the parent specification, in which a main pressure control valve 10 at an upstream part of the main is controlled by a pilot valve 12 in accordance with the pressures at spaced-apart points at the upstream part of the main, is modified in that the pressures at the spaced-apart points, one of which is downstream of the main valve 10, and the other of which is at the outlet of that valve, are applied through the two parts of conduit 32 to the opposite sides of the secondary controlling diaphragm 24 of the pilot valve, the primary controlling diaphragm 22 having the pressure at the upstream part of the main applied to it through conduits 25 and 68, and being exposed to the atmosphere on its other side. The arrangement is such that the direct pressure control of the pilot valve 12, and hence of the main valve 10, is modified in accordance with the flow in the main, i.e. with the collective demand of the consumers, so that when demand increases, the pressure will be increased to counter the pressure loss due to flow along the main.

Title: A method of distinguishing textile materials of differing qualities
IPC: G01N33/36
Filed: 1959-10-27
Abstract: Textile materials of different characteristics are distinguished in the course of manufacture of textile articles by a process comprising (a) sorting textile materials into two or more batches which have different characteristics, e.g. type of material, quality of material, counts of yarn or direction of twist, or which are intended to have different characteristics, (b) treating one or more batches with a substance or substances which will produce no change in the colour or shade of the material, or a shade or colour change which can be removed by a subsequent process, when viewed in daylight on ordinary artificial light but which will cause each of the batches to have a distinguishing shade or colour under radiations of wavelengths other than those in the visible spectrum, and (c) at a later stage viewing the batches of material under radiations which will bring out the distinguishing shades or colours.  The textile materials may be in form of fibres, slivers, webs, roving yarns or woven or knitted fabrics.  The substances used to treat the textile materials may be compounds which absorb radiations lying in the ultra-violet or infra-red range and appear colourless when viewed under natural or ordinary artificial light but appear coloured when viewed under ultra-violet or infra-red rays, e.g. sodium salts of certain naphthylamine sulphonic acids.  Suitable substances are Laurent's acid, Cleve's acid, Tobias acid, Bronner's acid, Peri acid, Amino-J-acid, Amino-G-acid, Koch acid, Fluolite C, Fluolite RP, Blancol N, Leucophor W.S. Liquid and Leucophor D Liquid (the word "Leucophor" is a Registered Trade Mark).  The Provisional Specification refers to a process for the separation of S- and Z-twist woollen yarns.  Specification 363,181 is referred to.

Patent GB-814305-A (GB)
Title: Improvements in or relating to electrical regulating apparatus, particularly for regulating temperatures and pressures
IPC: G05D16/20
Filed: 1955-12-20
Abstract: 814,305. Automatic control systems. WATSON, K. Sept. 26, 1956 [Dec. 20, 1955], No. 36446/55. Class 38 (4). [Also in Group XXXVI] The pressure-sensitive device (a Bourdon tube) 33 of an automatic pressure control system for a steam boiler is coupled to a potentiometer 24 having a slider 28 normally out of contact with the resistance winding 24<SP>1</SP> so as to reduce friction, a relay 27 bringing it periodically into contact. The potentiometer 24 forms with potentiometer 22 and resistances 25 and 26 a bridge network of which the out-of-balance current flows through a polarized D.C. relay 36; when this current exceeds a certain value it causes contact 37 to energize one or other of the relays R1, R2, to close one of the switches r1, r2 and move reversible A.C. motor 12 linked to an oil burner by connection 13 in the appropriate direction. The potentiometer 24 has a part 51 formed by a conductive metal strip so that at low boiler pressures maximum flame may always be obtained. The bridge is intermittently supplied with D.C. from the same source as that for relay 27, motor-operated cam contacts 18 interrupting the supply. Ganged switches S1 and S2 allow manual operation by control of potentiometer 23. The Provisional Specification describes a similar but simplified system in which the slider of the pressuresensitive potentiometer is permanently connected, and having a half-wave rectified D.C. supply for energizing relays corresponding to R1 and R2. The Provisional Specification also states that the temperature produced by an oil burner may be controlled by the use of a device which produces a pressure for the Bourdon tube which is a function of the temperature.

Title: Dispensing apparatus for roll material
IPC: A47K10/40
Filed: 1920-12-30
Abstract: 166,491. Johnson, G. T. Dec. 30, 1920. Roll holders for toilet paper which is used in short lengths. Two roll-supports 6 and 6<a> are adapted to enter the central portion of a roll, and a spring-pressed adjustable friction plate 7 is held against rotation by portions of the roll support 6 which engage slots in the plate. The plate 7 is pressed against the roll by a spring 8, fitted in a recess in the support 6 and its position is adjusted by means of a wing-nut 17 and collar 16 fitted to the spindle 10. The spindle 10 is hollow at one end and fitted with a spring-pressed plunger 11 which engages a slot in the supporting-boss 6a, thus preventing the pivoted arms, which support the bosses from a base-plate, from swinging out of position. The plunger 11 is operated by a pin 14 which.is slidable in a slot in the member 10, and which is only accessible when the roll is expended. If desirable the friction plate 7 can be held out of operation by means of the nut 17.

Title: Method and apparatus for feeding sheets
IPC: B65H3/24
Filed: 1958-11-13
Abstract: 863,346. Feeding sheets of differing lengths. LA BOMBARD, L. E. Nov. 13, 1958 [Nov. 25, 1957], No. 36514/58. Class 117 Cardboard sheets (Fig. 2) are fed from the bottom of magazine 84 by the flexible hooked fingers 74 of rotating drum 58. The sheets rest on fore and aft ledges 37 and 52 and on tensioned metal tapes 130, 131 secured at 52 and 133, and these tapes serve to guide the lowermost sheet beneath gates 44, 45 to the feed rolls 32, 33 whence the sheet passes rightwards to and between the endless belts 21, 24. Elongation of magazine (Fig. 2). The left-hand side of the magazine 84, including rear ledge 52 and rotating drum 58, comprises a cantilever unit carried by twin I-sectioned girder supports 91, 92, which slide telesccpicallv within fixed frame supports 89, 90. The cantilever unit is lengthened telescopically by rack-andpinions (e.g. 98, 101) driven manually by handle 111. The drive connection 123 between the drive mechanism 125 and the rotating drum 58 is likewise made telescopic. Flattening of lowermost sheets (Fig. 6). Presser machanisms 153 flatten the rearward edges of the sheets in the magazine 84 so as to facilitate the feeding engagement of the fingers 74. Each presser mechanism achieves this by a tip 183 which is brought down into engagement with the rear of the bottom three or four cards to press them flat just prior to the feeding movement of the fingers 74. The vertical reciprocation of tip 183 is effected by rock shaft 158 in the manner shown, shaft 158 being rocked by a cam 169 (Fig. 2) secured to the shaft 59 of the rotating drum 58. Likewise presser mechanisms 152 (Fig. 2) flatten the forward edges of the sheets. Alternative rotating drum 199 (Fig. 12). This modification of drum 58 is made to' be selectively operable by slidable handle 238. When the operator moves handle 238 to the right blade 225 moves under toggle influence to the right. This causes follower 221 to move into path 223 of cam 222 and rod 217 to move leftwards, and this latter movement acts through rod 212 and toggle 207, 208, to elevate feed fingers 205 to the operating position. Vice-versa, when the operator moves handle 238 to the left, follower 221 moves into path 224 of cam 222 and the feed fingers are withdrawn to the inoperative non-feeding position.

Filed: 1955-12-20
Abstract: 780,794. Wire rope slings. MEISEN, H. Dec. 20, 1955, No. 36540/55. Class 78 (4). A lifting sling comprises a number of steel cables 1, Fig. 2, joined by connecting members 2, each enclosing two or more cables, the sling having lifting shackles 5 at each end. In the construction of Figs. 2 and 3, the connecting members 2, which may be of steel or of rubber or like material, and may be of oval or rectangular section as indicated in full and broken lines in Fig. 3, each hold two cables 1 and are split, as at 14, for easy removal. The members 2 are arranged in contact in rows across the sling, each row being offset with respect to and in contact with the adjacent rows. The exposed parts of the cables on the outside of the sling may be protected by sleeves 2a. Alternatively the members 2 may be of tubular hose and in a further example adjacent connecting members and rows of members are not in contact ; in such a construction the exposed cables are preferably covered by sleeves of plastic material. In the construction of Fig. 7, the connecting members 11 each enclose all the cables which are held together in pairs by clamps 12. The shackles 5, Fig. 2, are connected to the cables 1 by a bolt 9 passing through eyelets 7 round which the ends 6 of the cables are held by aluminium seizings 8 die-pressed on to the cables.

Title: Improvements relating to electron microscopes
Inventor: HAINE MICHAEL EDWARD
IPC: H01J37/22
Filed: 1957-11-27
Abstract: 887,517. Electron microscopes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 25, 1958 [Nov. 27, 1957], No. 37012/57. Class 39(1) An intensifier plate comprises a thin, tightly stretched, electrically insulating plastic membrane 2 coated on one side with a film 1 of ' bombardment-induced-conductivity' material such as selenium. The film 1 is preferably, deposited on a metal layer 5 coated on the membrane 2; on the free face of the film 1 an anisotropically conducting layer 6 with high tranverse resistance is formed from gold smoke. The free face of the membrane is coated with a metal layer 4, on to which a high energy image beam is directed. The beam penetrates through the layers 4, 5 and membrane 2 into layer 1 thus increasing its conductivity. A low energy beam from electron gun 7 scans layer 6, and the layer 5 is held at the same potential as the gun to provide a datum to layer 1 at which the electron beam is repelled from the target. Between scans charge leaks away through the conductive parts of layer 1 and its replacement by the beam induces capacitatively a charge on layer 5; an amplified signal of which may be observed across load resistor 10 on cathode ray tube 16. Any charge collecting on layer 4 and membrane 2 is led away to earth. Electrostatic guard rings 13, 14 at +3 and +50 volts respectively may be provided to minimise the effects due to stray electrons. In a modification the plate 5 is kept at a high potential with respect to that of the gun cathode so that selenium layer will stabilise at the second secondary emission cross-over point. Specification 887,516 is referred to.

Title: Improvements in harvesters
IPC: A01D37/00
Filed: 1967-08-14
Abstract: 1,200,767. Harvesting machines. KUBOTA TEKKO K.K. 14 Aug., 1967 [13 Aug., 1966], No. 37209/67. Heading A1F. A reaper-binding machine is steered by handle 15 and has a number of crop dividing boards 110 having moving fingers 127 arranged to lift crop to prepare it for cutting by a reciprocating cutter 45 (Fig. 12a) from whence the crop is guided by rotating members 172, 164, 165 and 166 on to a table consisting of transversely extending boards 91, 92, 93, 94 between which are moving fingers 66, 71 arranged to transfer cut crop transversely beneath the dividers 110 to lie on a raised part 96 of the table and against a door 290. A pressure plate 185 and a bar 187 retain the stalks. When the stalks exert a predetermined pressure on the door 290, this rotates together with shaft 286 to initiate the binding cycle. A roller 295 associated with shaft 286 moves in a slot 299 to rotate members 298 whereby the pawl 301 is released and member 302 is pivoted by spring 307 so that roller 305 engages a projection 306 on a constantly rotating gear 276 to transmit drive to the disc cam 303 and the needle driving shaft 232. The needle 271 makes one reciprocating motion through the intermediary of the arm 275 and link 273. At the same time the needle driving shaft operates, through gearing, a bill and holder which knot the string supplied by the needle and then ejecting arms 250, 252 whereby the stalks are ejected laterally from the machine. On completion of one revolution of the needle drive shaft 232 the pawl 301 abuts against the pawl 300 and thus disengages the drive from the disc cam 303. To ensure smooth supply of string a packing arm 284 moves ahead of the needle 271. The string is supplied to the needle from a roll 24 via a pair of string brake elements, a tension arm and a guiding tube. Resilient bars such as shown at 178, 179 and 182 prevent entanglement of the stalks between the dividers 110 and a discharge conveyer 351 is arranged on a telescopic shaft 353. The various parts of the machine are driven from an engine which also drives the ground wheels.

Title: Improvements in or relating to soft rubber compositions and goods and process for their production
IPC: C08L7/00
Filed: 1934-12-29
Abstract: Rubber compositions for the production of soft rubber goods are made by masticating a mixture of compounded or uncompounded unvulcanized rubber and rubber prepared by the vulcanization of rubber in aqueous dispersions thereof.  In examples (a) an unvulcanized aqueous dispersion e.g. latex is mixed with a vulcanized aqueous dispersion e.g. vulcanized latex, the water removed and the mixture masticated; (b) raw rubber is mixed with a vulcanized aqueous dispersion and the mixture subjected to hot mastication until the water is evaporated; (c) raw rubber is mixed by mastication with the product obtained by removing substantially all the water from a vulcanized aqueous dispersion of rubber.  The dispersions may be natural or artificial, compounded or not, and preferably contain 2,5 per cent or more sulphur bound to the rubber and sufficient protective colloids and compounding ingredients to yield on inspissation a dry residue which may be easily crumbed.  The solid product obtained by inspissation of the vulcanized dispersion or the rubber compositions prepared therefrom may be washed to remove protective agents used during vulcanization such as alkalies and soap, and reagents such as waste soluble acceleraters.  Specification 405,407 is referred to.

IPC: G01R29/26
Filed: 1957-11-29
Abstract: 833,929. Television. STANDARD TELEPHONES & CABLES Ltd. Nov. 28,1958 [Nov. 29, 1957], No. 37286/57. Class 40 (3). [Also in Group XXXVI] In an arrangement for measuring the amount of noise present in a television link, means are provided for transmitting over the link a test signal, curve A, Fig. 1, consisting of synchronizing pulses 1 alternating with rectangular video pulses 2 of constant amplitude, whereby the crests of received video pulses, curve B, carry noise variations, means being provided at the receiving end of the link for separating the noise variations from the crests of the pulses and applying them to a power measuring device. The separation may be effected by an arrangement, as shown in Fig. 4, in which the received signals are first D.C. restored at 4 and then applied to an amplifier 5 which separates the pulses above level 6, curve B, Fig. 1. The output is applied via a phasesplitting amplifier 7 to further amplifiers 8 and 9 to produce oppositely-phased waves, curves C and D, Fig. 1, from the second of which the noise is eliminated by limitation in the amplifier 9. The waves are combined in equal resistors 12 and 13 to cause cancellation of the pulse portions, leaving the noise alone which is passed through an amplifier 14 and weighting circuit 15 to a noise power measuring device 16. Weighting circuit 15 may alternatively precede D.C. restorer 14. Pulses 2, curve A, Fig. 1, are chosen to be less than peak white and of an amplitude determined by anticipated noise such as to prevent noise peaks being removed in amplifier 5. Where the received signal is accompanied by transients 17 and 18, Fig. 3, which may interfere with the measurement, auxiliary pulses 19, which are shorter than pulses 2, may be added to the received signal by a pulse generator 21 and shaper 25 so as to displace the noise away from the transients. Amplifier 5 is modified so as to limit above level 20. Furthermore, where the received pulses arrive with a sloping crest, the auxiliary pulses may be shaped inversely to offset the slope. According to a modification, pulses 2 may be omitted from the transmission, so that noise is effectively measured at black level, and pulses are added at the receiving end by generator 21.

A coupling for mounting a sleeve 76 (e.g. on to which a strip is wound when slit from a wider roll) on a drive shaft 40 comprises a fixed inner housing 45 (e.g. cantilevered from a pivoted arm 18), through which the shaft 40 extends, axially-spaced bearings 58, 59 located between the housing 45 and an outer housing 61 along which can slide support members 64, 68, 71 so as to move springs 70, 75 into contact with the sleeve 76 as a result of rotation of the shaft 40 (e.g. by a belt 38 round a pulley 39). As shown a split ring 78 is clamped on the shaft 40 by a bolt 80 and mounts about a pivot axis normal to the drawing a gimbal ring 81 which in turn mounts two rollers 85. These engage the end face 77 of the member 71 which is formed as a cam with a pair of diametrally opposed valleys each having two slopes of 60 degrees extent about the axis of the shaft 40, so that rotation of this shaft drives the rollers 85 up a pair of the slopes pushing the members 64, 68, 71 together to expand the springs 70, 75 to grip the sleeve 76. The member 71 has a pin 72 engaging an axial slot 74 in the housing 61.
