Abstract: 1290114 Bonded fibre fabric SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 8 Jan 1971 995/71 Heading D1R Modacrylic fibres are bonded by applying a blend of solvent and diluent then heating. Copolymers of acrylonitrile with vinyl chloride (60%) or vinylidene chloride (40 or 50%) are specified. The fibres may be staple or continuous, in the form of an air laid or carded and crosslaid web, or yarns, slivers, tows or felts. The web may be needled or stitched before or after solvent bonding. Suitable solvents are γ-butyrolactone, N, N-dimethyl acetamide, N, N-dimethyl formamide, dimethyl sulphoxide, ethylene carbonate, propylene carbonate and N-methyl-2-pyrrolidone. The diluent, which must have a vapour pressure at 100‹C of 0.001 to 5 times that of the solvent, and must not dissolve the fibres, may be diethylene or triethylene glycol, iso-octanol, 2-phenyl ethanol, benzyl alcohol and butyl "oxitol". The blend may be applied to the fibres before or after formation of the web.

Abstract: 1295069 Strip fastener VELCRO FRANCE 2 Dec 1969 [3 Dec 1968] 58874/69 Heading E2S A fastener of the type having a plurality of resilient hooks 8, (Fig. 1) attached to a band 1, which can be attached to a second band having co-operating elements, has the hooks formed by cutting the loops below their crest, 6, and forming protruberances on one 11, or both cut ends. An apparatus for producing the fastener bands described above in which only one of the contents of the loops has a protuberance, comprises two large rollers 21, 22, Fig. 4, and a small diameter roller 31. The fastener loops are cut before they are fed into the apparatus, and the small roller 31 is of such a size that the two cut portions of the loops 9, 7 are separated as the fastener band passes round the roller. The band co-operates with fins 43 on roller 34, hot compressed air is blown from duct 52 through holes 48 in roller 34, between fins 43 so that the ends of portions 9 of the loops-are melted and form protuberances. The portions 7 of the loops are protected from the hot air by the fins 43. An apparatus for producing the fastener bands in which both cut'ends of the loops have protuberances, combines the action of cutting the loops 66, Fig. 5, with forming the protuberances. Cap 71 performs radial oscillations in step with the advance of the band 65. The loops are engaged in sockets 78, 79 in the cap and hot air passes through jets 81, 82 cutting the loops and melting the ends of the cuts to form the protuberances.

Abstract: 1320451 Impedance measuring bridge: measuring non-electric variables K A CHEESEMAN 22 Dec 1971 [27 Jan 1971] 3284/71 Headings G1N and G1U The out-of-balance signal from a bridge 1, 2, 3, 4 which includes at least one frequency dependent impedance, is rectified and amplified 8 and used to adjust the frequency of a Wien bridge oscillator 9 providing a constant amplitude supply to bridge, whereby if an unknown impedance is connected either across one arm or in series with one arm of the bridge the frequency of the oscillator when balance is attained will be proportional to the unknown impedance. As shown the circuit includes a linearizing circuit 5, and the frequency of the Wien bridge oscillator is determined by photo-cells 14, 15, and a lamp 16. However, mechanically switched resistors, or capacitors or thermistors could also be used. The unknown impedance may be resistive, e.g. a thermistor for measuring temperature which would be connected in series with bridge resistor 3, or capacitive e.g. from a displacement or liquid level transducer which would be connected across the bridge capacitor 4.

During the first cooling stage the oil is flowing; this stage ends when the wax begins to crystallize. In the second stage, the oil is in laminar flow, the cooling is at 10‹ to 40‹ C. per hour and continues to a temperature not above 25‹ C. A resinous oil (crude or product) may be added to the waxy crude either before heating or after heating but before the first cooling stage; this reduces the temperature at which crystallization of the wax begins, and therefore the time needed for the second cooling stage.

As shown in Fig. 1, the motor comprises a pair of coils (15) carried by a U-shaped core (14) co-operating with a permanent magnet armature 18 carried by member 16. The latter is mounted on inclined leaf springs 17 which impart a rotary component to the reciprocating movement of the member. The transducer comprises a coil 26 mounted in the housing at a position in which the field intensity from the motor coils (15) is a minimum and cooperating with a further permanent magnet 27 carried by member 16. Alternatively the transducer may comprise a photo-electric, straingauge, Hall-effect or piezo-electric device. Member 16 is shown coupled to a feed bowl 20 having a convex base on which objects fed from a hopper progress outwards to a helical feed track 22 extending round the wall 21 of the bowl to a discharge gate 23. In one form of control circuit for the motor, Fig. 3 (not shown), pulses generated by the transducer coil 26 are fed via a pre-amplifier (32) and pulse-shaper (33) to the input of a power amplifier (34) which also receives power from a main supply (35) whereby the power amplifier delivers pulses to the motor 13 which are phase and frequency locked to the signal from coil 26. Amplitude control means (36) are provided in the power-supply to adjust the supply to motor either automatically according to load or manually. Fig. 4 shows an alternative control circuit in which the pulses from coil 26 are fed to a trigger circuit 37 which controls, under the influence of the amplitude control 39, a gating circuit 38 in turn controlling the supply to the motor from source 35. Both circuits may include means for controlling the supply of objects to the feed bowl from a hopper.

Abstract: 1327297 Bonded fibre sheet SPRAYON RESEARCH CORP 14 May 1971 14899/71 Heading D1R [Also in Division E1] A thermally insulating mat is produced by mixing fibres and binder and projecting said mixture at a velocity of above 4000 ft./min. onto a collecting surface. Preferably rock or mineral wool fibres optionally containing some asbestos fibres are mixed with cementations binder and perlite or vermiculite filler in hopper Y by means of rotating finger N, fed by auger screw M to carding cylinder 9 and fall into the open upper compartment of revolving storgate B. As each compartment reaches the bottom position a high velocity stream of air and dry steam carries the fibres along flexible conduit C to gunhead E, which is also supplied with water. The gunhead may be a venturi type which wets the fibres before they leave the gunhead, or a multiple nozzle type which wets the fibres in mid-air. The air stream leaves the gunhead at above 4000 ft/min and thereby produces on the collecting surface a coherent layer that needs no tamping. The production of fire-resisting ceilings is described.
