Title: Improvements in variable speed transmissions
IPC: F16H47/08
Filed: 1947-07-31
Abstract: 632,407. Band brakes. FORD MOTOR CO., Ltd. July 31, 1947, No. 20744. Convention date, Dec. 13, 1946. [Class 103 (i)] [Also in Group XXIV] A contracting-coil brake comprises several turns of spring steel band 101, having one end 102 turned out and held by a flared tip in an anchor block 103 secured in the brake housing 11. The other end of the band has a slot 104 engaged by the end of a lever 106 constantly loaded by a spring 108 so as to cause brake application unless a cam 109 is rotated to press back, through a cam follower 114, the lever 106, and relieve the pressure of the lever on the end of the slot 104 so that the band is free to expand away from the co-acting drum 27. As applied, two such brakes are used to establish forward and reverse drive respectively in a motor. vehicle change-speed epicyclic gearing (see Group XXIV), alternate application of the brakes being effected by mounting a further operative cam for the second brake on the same shaft 87 as that of the cam 109, the shaft 87 being turned by an arm thereon connected by a linkage (not shown) to a lever preferably mounted on the vehicle steering column. The two cams are similar in shape but are reversed in relation to the shaft 87, being set thereon in such angular relationship that both brakes can be disengaged, but not engaged, simultaneously. The brake bands are pre-stressed so as to tend to expand into seating contact with the machined inner surface of the housing 11, and are preferably copper-plated on their inner surfaces to provide smooth engagement and reduce wear.
Patent GB-720516-A (GB)
Title: Making films and fibres from normally crystalline polymer latices
IPC: D01D5/42
Filed: 1952-08-18
Abstract: Films capable of disintegrating into fibres are made by depositing on a smooth water-impermeable surface a thin layer of a polymer emulsion containing at least 30 per cent solids content in which substantially all the polymer particles are amorphous and under 2000 Angstrom units in diameter and which are derived from a monomer or a monomer mixture consisting solely or predominantly of a compound having the formula <FORM:0720516/IV (a)/1> where X is selected independently and consists of chlorine, bromine, or cyano radical, drying the deposited layer, heating the resulting film momentarily to a temperature above its melting point, cooling the film rapidly, removing the film from the support and longitudinally stretching sufficiently to produce molecular orientation and to render the film capable of disintegration by friction into fibres.  If desired after the initial orientation, the film may be subjected to several stretching operations at elevated temperature, each stretching being performed at a higher temperature.  The polymer may be a homopolymer of vinylidene chloride, vinylidene bromide, vinylidene chlorobromide, vinylidene cyanide, vinylidene chloro-cyanide or vinylidene bromo-cyanide or a copolymer of these monomer with vinyl chloride, vinyl bromide, vinyl acetate, acrylonitrile, methacrylonitrile, styrene, chlorostyrene, or methyl or ethyl acrylate or methacrylate.

Abstract: 961,050. Packaging-machines. CONTINENTAL CAN CO. Inc. June 8, 1961 [Aug. 3, 1960], No. 20801/61. Heading B8C. Containers such as bottles grouped for packaging, e.g. in a wrap-around paper carrier, are separated from each other by a divider made from a blank having cut-out portions bent out - to form transverse partitions, the remaining portion providing a longitudinal partition. In a machine for inserting the dividers, the blanks 20 are fed from a hopper 21, Fig. 3a, on to a conveyer by suction cups 25 and are held flat by rails 52 and 53 as they are advanced by conveyer chains 24, Fig. 2b. Partitions 40 and 43 of the blank are forced upwards by lugs 58 rotating about a shaft 60 (Figs. 2B, 3B) and partitions 41 and 42 are then forced downwards by a rotating folder 64 and away from each other by a plate 80. As the blank continues to advance, bars 86 and 87 fold the partitions 40 and 43 down upon each other, above guide 83, and it is then drawn between moving belts 99 and 100. The partitions 40 and 43 remain folded and the partitions 41 and 42 are held away from each other by contacting rollers 110 (see particularly Fig. 10). As the blank approaches pulleys 103 and 105 the partitions 40 and 43 are forced outwardly by a deflector 114 and it is then ready to enter between the containers. The containers 37 are urged forward by a conveyer 117. Members 118 attached to chains 119 (only one chain shown in Fig. 4) enter between the containers to separate them transversely. The rows of containers may be separated longitudinally by either tilting the conveyer 117 at the middle (Fig. 9) or by a wedge-like member forcing apart the advancing rows (Figs. 12, 13, 17, not shown). The belts 99 and 100 insert the erected divider blank 24 and a wheel 137, Fig. 10, ensures that the blank is completely seated, as the containers are moved away. A modified form of divider is described, in which two superposed blanks have interlocking arrangements to maintain the partitions erect (Fig. 14, not shown).

Title: Improvements in flexible tubes
IPC: B29C53/58
Filed: 1957-07-03
Abstract: 859,950. Non-metallic tubes. RIST'S WIRES & CABLES Ltd., and SILVER, R. J. July 2, 1958 [July 3, 1957], No. 21008/57. Class 99(2). A method of producing a flexible tube comprises a coating or covering a mandrel with a synthetic plastic material, e.g. polytetrafluoroethylene, the physical properties of the mandrel, when the coated or covered mandrel is subjected to an elevated temperature, being so affected that the mandrel can be removed from the coating or covering which then forms the finished tube. The mandrel is wound with one or two layers of plastic tape on which a braid of resin-bonded glass fibre is applied, the process being repeated until the required wall thickness is obtained. The composite article is then cured at a relatively high temperature and the mandrel removed. Alternatively, the composite article is cured, coated with a dispersion of synthetic resin and again heat treated at a higher temperature so as to remove the mandrel. The mandrel may consist of a material which at the curing temperature is capable of charring, e.g. cellulose fibres or paper string, or of crumbling, e.g. a gypsum base composition. Production of the tubes may be continuous.

Title: Improvements in and relating to recording apparatus for electric current impulses
IPC: H04L13/18
Filed: 1921-08-08
Abstract: 188,391. British Thomson-Houston Co., Ltd., (General Electric Co.), Aug. 8, 1921. Addition, to 130,762. Continuous apparatus for developing, fixing, washing, and finishing.-In apparatus for photographically recording selectively received current impulses as in the parent Specification, means are provided for varying the time of immersion of the photographic strip in the developing &c. tanks, and for drying the strip in a current of heated air. The driving means for the tape is arranged to take up slack automatically, and an indicator shows the amount of unexposed strip on the supply reel. The apparatus has chambers B - - E, respectively supplied with developer, fixing solution, water for washing the strip, and heated air for drying purposes. The strip passes in a depending loop through each of these chambers, passing round a pulley the height of which can be adjusted to control the extent and time of immersion. Chambers B, C have gaugeglasses B<3> showing the level of the solution. A pointer moving over a scale 40 and operated by a pivoted member 38 resting against the supply roll 36, indicates the amount of unexposed strip. The strip is guided over pulleys, of which the pulley 60 is driven through a slipping clutch (not shown), so adjusted that the pulley takes up slack but is unable to draw the strip from the feed roll, the feed being effected by a positively driven pulley 47. The drive is given by a motor 48, rotating a shaft (not shown) extending the length of the apparatus. Associated with each chamber B - - E are two gear wheels (not shown) rotated in opposite directions through gear from the shaft. A third wheel, normally out of engagement, is adapted to be engaged with either of these two wheels, so as to drive, in one direction or the other, a sprocket over which passes an endless chain carrying the pulley within the bight of the strip immersed in the chamber. This pulley is thus raised or lowered. The engagement above referred to may be effected by hand, or by one or other of two electromagnets, the circuits of which are controlled by a hand-operated switch. A switching device driven from the shaft and thrown over by adjustable stops, serves to de-energize the magnet when the pulley has been raised or lowered a distance predetermined by the position of the stops. Contacts are also provided which automatically stop the motor when the pulley reaches the upper or lower limit of permissible travel. The developed tape, reflected in an inclined mirror, may be read through a ruby-glass window.

Title: Improvements in and relating to overload thermally-operating circuit breakers
IPC: H01H71/40
Filed: 1930-07-11
Abstract: 360,843. Automatic circuit-breakers ; electromagnetic switches; switches partly electromagnetic. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; '2, Friedrich Karl-Ufer, Berlin.) July 11, 1930, No. 21062. Convention date, July 11, 1929. [Class 38 (v).] A circuit - breaker or switch, which responds to overload and in some modifications to underload and which may also be moved " on " and " off " by hand or by remote control, comprises a bimetallic strip 1, which carries a contact 2 engaging a contact 4, and a dead-centre spring 8, which is fixed to the strip 1 at its one end and may have its other end movable. The strip I is V-shaped and carries the current, and upon a moderate continued overload moves to the right, the counter contact 4, which is mounted on a spring 6, and may also be influenced by an adjustable spring 9, following it till it strikes a stop 5, and the contact 2 then continuing to move so as to break the circuit under the influence of the spring 8 which has moved over the deadcentre. The parts may be so adjusted that when the bimetallic strip cools down, its tendency to return to the left overcomes the spring 8 and the switch closes again. To give a quick release on a sudden large overload, the strip 6 is of magnetic material or carries an armature 11 adapted to be attracted by an electromagnet 14 in the circuit, and the magnet 14 may have additional polepieces 27 adapted to attract a pivoted armature 21, the lower movable end of which is fixed to the lower end of the spring 8. The switch may also be opened or closed at any time by moving the armature 21 and thereby the spring 8 to the right or to the left either hy hand or by energizing one of two coils 23, 22. In the latter case, the energizing circuit of the coil 22 or 23 may be broken automatically by the opening movement of the contact 4 opening auxiliary contacts 38, 39, Fig. 4, the contact 4 moving in a recess 34 and creating a wind which passes through gaps 40 in the sides of the recess and blows out any arc at the contacts 38, 39. Also, in order to make the movement very sensitive, a spring may be arranged to act on the armature 21 so as nearly to balance the force on it due to the spring 8 in the closed position of the switch. The switch may also be adapted for underload response by letting a no-volt coil such as the coil 22 act on the armature 21 in opposition to a spring. The contacts 2, 4 are provided with silver insertions 3 and have electrodes 5, 15 to take the arc which is blown out by polepieces 16 energized by the coil 14.
