Title: Open end spinning machine
IPC: D01H4/08
Filed: 1974-11-15
Abstract: 1452848 Open-end spinning machines FRIED KRUPP GmbH 15 Nov 1974 [17 Nov 1973] 49587/74 Headings DID and D1N In an open end spinning machine whose opening roller 2 is at least approximately coaxial with the spinning rotor 1 the opening roller is caused to rotate by the spinning rotor without making contact with it. This may be achieved by the entrained airflow of the spinning rotor or as shown by a magnet 15 in the opening roller which induces eddy currents in the spinning rotor and hence generates a magnetic coupling. The strength of coupling is adjustable by means of a screw pin 7 on which the opening roller is mounted and which is axially adjustable. Adjustment may alternatively be by means of an hydraulic piston cylinder assembly.

Title: Waveform information processing
Inventor: HIRSCH PETER MAX
IPC: G03H1/08
Filed: 1970-10-21
Abstract: 1280246 Seismic data processing INTERNATIONAL BUSINESS MACHINES CORP 21 Oct 1970 [26 Nov 1969] 49916/70 Heading H4D [Also in Division G2] Data 9 (e.g. a seismic section) is processed by illuminating it with incoherent waves and filtering the resultant waves with a processing member 16, having controlled phase retarding areas and constructed from an overall matrix of values from which all negative values have been effectively removed, to give in a predetermined output plane a resultant distribution of energy corresponding to the processed data. The incoherent waves are preferably light waves. The negative values are removed by adjusting the matrix of values by a suitable constant. The output image may be a vertual image 17, 18 or it may be so located as to be scanned by a vidicon for subsequent display. Prior to such display a negative bias corresponding to said constant is added. The processing member 16 is a kinoform. The data 9 may be either a transparency or the face plate of a cathode ray tube. In an alternative embodiment the negative values are removed by dividing the member 16 into two sections 35, 36 of controlled phase retarding areas. One of the areas 35 is constructed with all the positive values, and the other 36 with all the negative values. The light output from each are subtracted to give the processed data. The subtraction is done electronically by scanning each pattern with a synchronized vidicon 38, 39 the outputs of which are summed and displayed. Desirably the output from member 36 having the negative values is passed through a half wave plate prior to optical summation. In a further alternative the processing member may include four sections corresponding to the positive and negative real and positive and negative complex values of the said matrix. In this embodiment the incoherent light is caused to pass through one half and one quarter wave plates prior to illuminating the negative complex section, a one half wave plate prior to illuminating the negative read section, a quarter wave plate prior to illuminating the positive complex section. The incoherent waves may be sonic or ultrasonic instead of light.

Title: Apparatus for transferring coded information between relatively movable units
IPC: B61L25/02
Filed: 1963-12-18
Abstract: 999,087. Train position indication; train identity. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 18, 1963 [Dec. 31, 1962], No. 50062/63. Heading B7N. [Also in Division G4] An arrangement for producing a signal which is a function of the position of a train on a track comprises at each of a number of wayside locations a coded unit comprising an I-section beam 12 clamped to rail 11 with part of its top flange 15 cut away, to form teeth which co-operate with a train carried differential transformer 20 to generate therein a series of clock pulses and a part 16 cut away to similarly generate in differential transformer 30 a series of signals indicative of the wayside location identity in binary code and means on the train for processing the information and transmitting it automatically or on request to a central control office. The signals from the clock pick-up transformer 20 and the data pickup transformer 30, which are fed from oscillator 10, are supplied to demodulators 40 and 50 respectively, and the data information is fed into a shift register 60 which is stepped by means of the clock pulses. The locations are positioned one mile apart and the position of the train intermediate the locations is determined by an odometer 100 coupled to the train wheels which provides at its four output terminals a signal in binary form indicating the number of tenths of a mile travelled by the train since passing the last location. When the central station requires the train position, read out means on the train are energized by a signal at frequency f1 sent via transmitter 130 at the central office to receiver 120 on the train. The read-out means includes a stepping switch which scans in turn the output terminals of the shift register at which an output signal representative of the last location passed is presented and the odometer terminals which present the intermediate position information. The output of the read-out means is passed to a transmitter 90 on the train which transmits the information at frequency f2 to a receiver 150 at the central office. The arrangement may also be used to identify a passing vehicle in which case the coded I-section beam is carried by the vehicle and the reading apparatus is positioned at the wayside.

Title: Wire strippers
IPC: H02G1/12
Filed: 1970-10-22
Abstract: 1332690 Wire strippers IDEAL INDUSTRIES Inc 22 Oct 1970 [22 Oct 1969] 50148/70 Heading H2C A wire stripper 10 consists of a pair of wireclamping blades 12, 14 and a pair of stripping blades 16, 18 mounted on a pair of levers 20, 22 which are pivotally connected together by a pivot pin 24. Handles 26, 28 are attached to levers 22, 20 by means of pins 34, 36 positioned in holes in levers 20, 22 and arcuate slots in the handles. A latch plate 50 is attached at one side to lever 20 by the pins 34. On the other side of the latch plate 50 is a ridge 58 next to which there is a latch button 64 positioned in an opening in the lever 22. When pressure is initially applied to urge the handles together, the blades 16, 18 are allowed to penetrate the insulation before the levers separate, as movement of the levers is prevented initially by button 64 bearing against ridge 58. On further pressure on the handles, the plate 50 bends away from lever 22 thus allowing button 64 to pass over the ridge 58, and the levers to separate. The button 64 then bears against the other side of the ridge, preventing the levers from closing, and therefore allowing the wire to be removed.

Title: Method of making polyvinyl chloride films from polyvinyl chloride powder
IPC: B29D7/01
Filed: 1971-10-29
Abstract: 1314297 Coating RANSBURG CORP 29 Oct 1971 [16 Nov 1970] 50365/71 Heading B2E [Also in Division B5] Films are made from a vinyl chloride polymer powder which contains at least 90% (by weight) of polymerized vinyl chloride units and which does not fuze to form a film when heated in the absence of pressure. The polymer is substantially free from copolymerized monomer units which would soften the polymer or increase its solubility in solvents. The powder is formed, preferably by electrodeposition, on to a supporting substrate, which may be metallic, and there exposed to the action of the vapour of an organic solvent for polyvinyl chloride. The vapour is at a temperature of at least 100C. The particles are at a lower temperature than the vapour, preferably between 10 and 25C below it, and the vapour condenses on to the polyvinyl chloride and freezes the particles into a film. The vapour may be an inert solvent, e.g. a ketone or an unsaturated monomer such as styrene, vinyl toluene or methyl methacrylate, which are solvents for polyvinyl chloride, or a mixture of such a monomer with a solvent which has a higher boiling point. The monomer will polymerize at deposition on the film; polymerization may be enhanced by baking. The powder is usually exposed to the vapour for between 10 and 80 seconds, after which excess solvent is removed, either by simple evaporation in the air or by force-drying with warm air.  The powder may contain a small proportion of polymerisable monomers such as styrene, vinyl toluene, methyl methacrylate, or a polyacrylate or polymethacrylate or be a copolymer containing an unsaturated acid such as fumaric, itaconic, crotonic, methacrylic or acrylic or methyl methacrylate or vinylidene chloride in small amounts. An initiating catalyst, such as a peroxy compound, may also be present. Examples illustrate the preparation of coatings on a mild steel substrate by use of a vinyl chloride homopolymer powder, with pentoxane as solvent or a 1:1 by weight mixture of styrene and methacrylate as solvent.

Abstract: 1,269,349. Valves. H. D. PASCHKE. 17 Oct., 1969 [25 Oct., 1968], No. 51089/69. Heading F2V. [Also in Division G4] A fluid logic element has a number of parallel laminµ having apertures for switching elements and bounded by upper and lower plates. The upper plate is covered by a cap. Fluid under pressure admitted between the cap and the upper plate compresses the stack of laminµ and plates to prevent fluid in the apertures leaking between the laminµ. The laminµ may be circular and made of plastics. In one embodiment, Fig. 1, the upper plate 7 has a greater surface area than do the laminµ 3-7. Fluid is admitted via duct 12 to the space between the cap 2 and the upper plate 7. Fluid at the same pressure is admitted to at least some of the apertures containing the switching elements (e.g. 9), but is unable to leak because of the pressure on the upper plate 7. As shown the lower plate is held loosely in the cap by pins 19, and the plates are maintained in the correct alignment by pin 20. The element is secured to a structure 23 as shown. In a second embodiment, Figs. 3, 4 (not shown), the cap does not extend over the laminµ as in Fig. 1, and the logic element is secured to the structure (23<SP>1</SP>) by a bolt (30) which passes through the stack and screws in to the structure. The fluid is admitted to the space beneath the cap either via a duct (12) formed through the stack, or via a duct formed coaxially through the bolt. The laminµ may have relieved parts so that the mating upstanding parts (35) have lesser area than the area of the upper plate.

Title: Improvements in or relating to the preparation of polymers and co-polymers of acrylonitrile
IPC: C08F20/44
Filed: 1963-12-30
Abstract: Granular polymers and copolymers containing at least 85% by weight of acrylonitrile are prepared by a process wherein a polymerization catalyst soluble in acrylonitrile and insoluble in water is dissolved in the starting monomer(s), the resulting solution is dispersed in the form of droplets in water used as polymerization medium, and polymerization is effected in the absence of inorganic compounds, the ratio by volume of water to the starting monomeric material being between 2:1 and 5:1 and the monomeric material being maintained by stirring in the form of droplets in the water, whereby the diameter of the polymer granules obtained is from 5 to 500 microns.  Suitable catalysts include lauryl, oleyl and benzoyl peroxides.  Comonomers specified are methyl acrylate, vinyl acetate, methyl, ethyl, n-propyl or isopropyl monoester of itaconic acid (where the carboxyl group adjacent to the methylene group is esterified), methyl, ethyl or n-propyl mono-ester of maleic acid, vinyl pyridine, and methyl, ethyl or n-butyl ester or amide or anilide of vinyl sulphonic or allyl sulphonic acid. A chain transfer agent, e.g. lauryl mercaptan or ethyl mercaptoacetate, may be included in the monomer phase of the reaction mixture. Instead of, or in addition to, stirring, dispersion of the monomer droplets can be maintained by the use of a substance such as polyvinyl pyrrolidone, polyvinyl alcohol, polysodium acrylate or sodium carboxymethyl cellulose. Fibres and yarns can be formed from the polymers dissolved in a solvent such as dimethyl formamide.

Abstract: 1,216,029. Induction energy and power meters. SIEMENS A.G. Oct. 17, 1969 [Oct. 17, 1968], No.51223/69. Heading G1Q. To prevent disc 10 of a polyphase induction energy or power meter rotating under conditions of negligible load, a first fixed magnetic member 7 co-operates with a magnetic member 8 rotating with a disc to hold the disc still when there is negligible current in the current coils but all the voltage coils 11, 21, 31 (or at least coil 11) are energized, whilst a second fixed magnetic member 12 co-operating with the same or a different rotating magnetic member takes over the function of member 7 when only some, but not all (and in particular not coil 11) the voltage coils are energized. The three phase meter shown has current coils on cores 4, 5, 6 and star-connected voltage coils 11, 21, 31, and is provided with light load compensation (not shown) to overcome friction, &c. No-load drift is normally prevented by the cooperation between tongue 7, magnetized by coil 11, and vane 8, but should the supply to coil 11 fail member 12 is arranged to become magnetized instead. This is achieved by energizing member 12 from a further coil 13 connected between the star point of the voltage coils and the neutral of the power system to which the meter is connected.
