Title: Pile fabric like products
IPC: B29C48/08
Filed: 1969-03-06
Abstract: 1,213,772. Pile fabrics. VELCRO S.A. 6 March, 1969 [12 March, 1968], No. 12033/69. Heading D1K. A pile fabric, e.g. hook and loop fastening material, is made by encapsulating a sheet of threads in low melting point metal, corrugating the sheet removing part of the metal to expose parts of the threads and then removing the remainder of the metal to leave the threads attached to the backing as upstanding loops. When being encapsulated in the metal the threads may also be shogged sideways before corrugating to produce fabric whose pile loops are shagged sideways. Referring to Fig. 2 threads 12 from a beam 10 in a refrigerated compartment A pass through grooved rollers 14 to a metal extruding die 17 with thread guide plates which are reciprocated axially of the beam 10 to produce a sheet of metal encapsulating the threads (Fig. 8, not shown). The sheet is then conducted through a chilling trough 20 and a tempering trough 22 from which it is drawn and corrugated by rolls 24 to produce a sheet with "open" corrugations (Fig. 10, not shown). The sheet is then fed through die plates 144, 146 to rollers 28 which run at a lower peripheral speed than the rollers 24 so that the corrugations are compressed together (Fig. 11, not shown). The sheet then passes onto a conveyor 30 where hot gas from nozzles 34 melts the top surface of the sheet and the molten metal is sucked away by pipes 36 to expose the loops of threads (Fig. 12, not shown). A backing is then applied from a roll 38 and adheres to the exposed loops of the encapsulate (Fig. 13, not shown). The laminate then passes around a refrigerated roll 50 which cools the backing whilst nozzles 52 blow hot gas onto the laminate to remove the remainder of the metal. The whole equipment is enclosed in a container filled with inert gas.

Title: Improvements in or relating to thermionic valve circuits particularly for use in television
IPC: H03K4/43
Filed: 1936-04-29
Abstract: 479,113. Valve generating circuits. BLUMLEIN, A. D. April 29, 1936, No. 12118. [Class 40 (v)] An amplifier for supplying saw-tooth current to the scanning-coils of a cathode-ray tube is provided with a negative reaction connection which feeds back to the input circuit saw-tooth potentials proportional to the current in the scanning-coils. As shown in Fig. 1, a condenser 1 is slowly charged through a resistance 2 and is discharged through a valve 3. The upper plate of the condenser 1 is connected through a coupling-condenser 5 to the grid of the amplifier 7 the plate of which is connected through a coupling-condenser 9 to the primary coil 10 of the output transformer, the scanning-coil 11 being in the secondary circuit. A leak resistance 6 is provided in the grid circuit and the grid is biassed by a condenser-shunted resistance 18 in the cathode lead. The negative feed-back is provided by connecting the lower plate of the condenser 1 to the junction of a resistance 13 and inductance 12 connected across the transformer coil 10, this connection serving to maintain a true saw-tooth output, despite distortion in the valve 7 and distortion due to the inductive load on that valve. The ratio of inductance 12 to resistance 13 is the same as in the scanning circuit. A supplementary condenser 11 may be connected directly between the grid and earth to supply a sawtooth potential to the grid independently of feed back. In Fig. 3, the shunt inductance 12 and resistance 13, are replaced respectively by a resistance 14 and capacity 15. A further series condenser 17 and shunt resistance 16 may be provided as shown. The Specification indicates the correct proportion of the reactance and resistance elements in relation to the inductance and resistance of the transformer and the scanning-coils. In Fig. 4, feed-back is taken from a circuit including a third winding 20 on the transformer 10. The circuit may comprise a connection to the cathode of the valve 7, a condenser 22 and a resistance 24, the latter being bridged by a resistance-reactance shunt 23, 21 with the junction connected to the lower plate of the condenser 1. The condenser 1 may be on the grid side of the coupling-condenser 5 and leak 6. Self-oscillation may be prevented by connecting a condenser 25 and resistance 26 between the high-potential end of the third winding 20 and the anode of the valve 7. The discharge valve 3 may he of the blocking- oscillator type. Specification 401,990 is referred to. According to the Provisional Specification the valve 7 may supply scanning-voltage to deflecting -plates.

Title: Gear Grinding Machine.
IPC: B23F1/02
Filed: 1968-03-13
Abstract: 1,191,402. Gear grinding. LEAR SIEGLER Inc. 13 March, 1968 [18 April, 1967], No. 12216/68. Heading B3D. A gear grinding machine has a rotatable work spindle 18 arranged in a fixed position on a base 10, a grinding wheel W reciprocable relative to the workpiece G in a direction parallel to the spindle and mounted so as to be angularly adjustable about an axis perpendicular to that of the spindle, mechanism including an adjustable sine bar and follower for causing timed angular movement of the work spindle in response to said reciprocal movement and a crowning slide associated with the grinding wheel support and movable transversely to the direction of reciprocation to effect crowning of the gear G. Fluid pressure cylinder unit 32, 34 reciprocates a slide 36 parallel to the work spindle 18 and the grinding wheel column 20 is adjustably coupled to the slide 36 for movement therewith by adjustable rods 46, 50, 38 and fluid pressure operated latching means 40, 44. Wheel W is angularly and vertically adjustable on the column 20. Rotary movement of the spindle 18 is derived from transverse movement of a rack 74 (Fig. 2) which is in mesh with a gear 75 on the spindle 18 and which is mounted in a slide member 76. Angularly adjustable sine bar 94 together with follower 98 and drive pin 100 causes transverse movement of the slide 76 and rack 74 when the slide 36 is reciprocated by fluid pressure unit 32. This causes rotary movement of the gear as desired for providing helical teeth. In order to index the gear G by one tooth space (one side of a tooth only being machined at a time) a fluid pressure unit 88 is operable to shift the rack 74 relative to the slide 76 by means of inclined cam slot 84, follower 82 and drive pin 80. Adjustable abutment means 90 limit the extent of this indexing movement. Crowning is effected by the action of an adjustable sine bar 126 through follower 122 and arm 120 on a crowning cam 110; the cam 110 bears on followers 112, 114 attached to a transverse crowning slide 108 mounted on slide 36, and causes transverse movement bodily of the sine bar 94 mounted thereon with consequential modification of the rotary motion of the gear G. The grinding wheel support column 20 is movable to an end position where a vertically movable wheel trimmer 66, 68 can be brought into operation.

Abstract: 948,055. Cable harnesses. LING-TEMCOVOUGHT Inc. April 6, 1960 [April 6, 1959], No. 12230/60. Heading H2C. A multiconductor cable comprises a plurality of elongated conductors provided each with its own insulating sheath and slidable relative to each other the whole being encased in a rigid cover of a hard-curing resin moulded about the conductors. Fig. 1 shows a number of insulated conductors 12 which may be of various cross-section and may include coaxial cables. The various conductors may be insulated with P.T.F.E. in order to allow them to slide on each other and are built up into a harness of the required shape fastened together with temporary spot ties of twine. The harness is then laid in the female section of a mould 54 previously lined with the material of which the casing is to be formed. This material may be of glassfibre cloth impregnated with a hard curing resin and must be adhesively imcompatible with the material of the conductor sheaths. The portions 62, 64 of this material are folded over as shown dotted (Fig. 9), and the male portion 53 of the mould is put in place with sufficient pressure to compact the cores to the desired shape and the pressure is maintained until the cover resin has set to a rigid dimensionally stable state. In the finished device shown in Fig. 1, strengthening metal inserts are provided in the walls of the casing at bends. Raised portions 40 are provided to enable a certain number of conductors to be lead out, where the number of conductors in the channel is reduced, for example because some have left through a cross passage 33, the cross section of the channel may be reduced. Where conductors leave the moulded passage they may be protected by a flexible member 41 consisting of a glass-fibre cloth exterior and P.T.F.E. interior, the end of the tube being moulded into the casing. At the end of the casing, for example at 18, where conductors leave a tube may be flared. The casing may be separated from a further casing 47 by a number of uncased conductors 45.

Abstract: 316,600. Marks, A. H., and Russell, P., (Representatives of Marks, E. C. R.), (Deutsche Erd÷l Akt.-Ges.). April 30, 1928. Right to Patent relinquished. Hydrocarbons, cracking.-In a process for cracking heavy hydrocarbons in which the heating, conversion and separation zones are entirely separate, the heating zone is divided into two parts such that the heat supplied per unit length up to the point at which the lowest cracking temperature is reached (about 390‹ C.) is less than the heat supplied per unit length from that point to the end of the heating zone where the desired cracking temperature is attained. A serpentine tube is divided into sections A, B and C, of which A and B are heating zones and C the cracking zone. Flue gases are supplied from burners D and G and adjustment of temperature is effected by valves E1 - - E5, F and H. The compartments A and B are in some cases separated by a wall. The converted product passes through a spraying valve R into a separator J surmounted by a distillation column K. A pump N feeds crude oil from a storage M to a preheater L where it is heated by the heavier distillate from column K, whence it passes to the heating-coil A. Heating by gas may be supplemented or replaced by electric heating, and in section B the oil may be passed through molten tin, lead, antimony &c. The heating gases may also be used in countercurrent to the oil.
