Title: Injecting Thermoplastic Material
IPC: B29C45/00
Filed: 1967-01-12
Abstract: 1,177,793. Injection moulding. SOC. POUR LA TRANSFORMATION DES MATIERES PLASTIQUES STAMP. 12 Jan., 1967 [15 Jan., 1966], No. 1649/67. Heading B5A. In a process for filling a cavity in a rigid mould or component, or for compensating for shrinkage of the material during cooling, thermoplastic material is injected into the cavity in molten or plastified form through a conduit B which passes through the wall of the cavity and is slidable therein but makes sealing contact with the said wall, the conduit being progressively withdrawn during the injection. In one example, Fig. 1, a shoe last is made in a mould A by injecting plastics material into a pot 3 from where it is transferred into the mould through the conduit B. When the mould is full a valve 5 is closed and hydraulic pressure is applied through a channel 14 to a cylinder 11 fixed to the pot 3 and slidable on a fixed piston 12. Any depressions caused by shrinkage during cooling are thus filled up. The conduit B is gradually withdrawn by means of a ram 6, 7, 8. In a modification, Fig. 2, the mould A is filled by an injector D which also fills a reservoir in a cylinder 3 above a piston 2. After filling of the mould A, the machine D is cut off and the conduit B withdrawn as in the earlier example, the reservoir being kept under pressure by a device (not shown). In a further example, Fig. 3 (not shown), a body of complex shape is formed using four withdrawable conduits (B) while in Fig. 4 (not shown), a cavity (16) in an already formed object is filled. The conduit B may comprise a single, double or triple walled tube surrounding a central hollow sleeve (20), Figs. 5-7 (not shown). The hollow spaces may contain heating or cooling means.

Filed: 1929-01-18
Abstract: 321,603. Adler, F. Jan. 18, 1929. Addition to 317,122. Resist printing; impression surfaces. - In an apparatus for printing a fabric with wax or other resist as described in the parent Specification, a number of printing-rollers are mounted on a revoluble support so that a number of different patterns can be selectively printed in succession. As shown, three printing rollers d, d<1>, d<2> provided with relief printing-plates are mounted on a revotuble support D so that any roller can be moved into the printing position, occupied by the roller d in Fig. 1, as required. The web b to be printed passes from a roll a round guide rollers c, g so as to contact at least half the periphery of the roller d and thence either direct to a dye bath or to a winding-roll j on which it is wound with a protecting web o. The endless resist web e passes round guide rollers c<1>, c<2>, round the roller d and guide rollers c<3>, f, to heated tubes F<1>, F2, F<3> and a melting trough K to remove residual resist, and thence under a wax &c. spreader L to be recoated, and through a cooling chamber m. The webs e, b are pressed against the roller d by a calico or other band z passing round the rollers c<2>, c<3> and round a resiliently mounted roller c<4>. The roller c<2> and the adjacent roller c, and the rollers c3, g are mounted in blocks x, x<1> slidable horizontally in guides in a frame y which, when released from spring latches y<2> is raised by weights W<1>, W<2> so as to allow of the revolution of the roller support D. The release of the frame y from the latches is effected by moving the blocks x, x<1> away from one another by the rack and pinion mechanism shown. The spreader L, Fig. 2, comprises a trough heated by steam pipes W and Q, and through the bottom of which pass strips of felt n, which engage the web e to spread the wax evenly thereon. Electrically heated boxes r arranged between the strips n are of corrugated form to provide passages for the flow of wax. The flow of wax down the strips n can be regulated by turning a series of pivoted members t' of oval section so as to grip the felts and more or less compress them. The members t' are operated by stems t<2> engaging a grating t operable by a lever S. When the spreader is not in use, a tray u is slidden beneath the lower ends of the strips n.

Title: Improvements relating to the gearing of time indicating mechanism
IPC: G04B13/00
Filed: 1944-02-03
Abstract: 575,904. Clocks. STOTT, H. T. Feb. 3, 1944, No. 2017. [Class 139] [Also in Group XXIV] Consists in planetary gearing of light construction suitable for the motion-work of clocks, for use in synchronous electric clocks and clockwork toys. The gearing comprises a fixed wheel a, the teeth of which are formed as tongues struck from one of the clock plates b and there are eleven such teeth. Nested in the wheel a is a rotatable wheel c having twelve axially extending teeth d. A planet-wheel e is rotatably carried on a stud f in a carrier g, is flat, being stamped from sheet metal, and engages the teeth of both the stationary and rotatable wheels. The carrier g is fixed to an arbor h carrying, e.g. a minute hand j and the wheel c is secured to a cannon k which carries, e:g. the hour hand l. The arbor h and cannon k rotate in the same direction with a velocity ratio of 12 to 1. If the fixed wheel had 13 teeth to the 12 of the movable wheel, the ratio would still be 12 to 1, but the directions of rotation would be opposite. Several modifications are described. In a modification, Fig. 4, the teeth a, d are of the same diameter and face one another, the planet wheel e having two sets of teeth n, m in different planes to engage both wheels. In modified forms of Figs..1 and 4, the planet-wheel engages the wheels a, c externally. In Fig. 9, a planet e on the carrier g engages wheels a, c, the latter wheel forming a carrier for a planet o which engages a movable wheel s and a fixed wheel q. With 60 teeth d and 59 teeth a, 11 teeth q and 12 teeth r, the hand would become a seconds hand, the hand l a minute hand and the hand u an hour hand. In a modification of this construction, the teeth instead of being struck as tongues are formed as straight pins. According to the Provisional Specification, the gearing may comprise an annulus with internal teeth, a relatively large sun and a relatively small planet pinion engaging both the annulus and sun-wheel. The planet which may be carried on a disc eccentrically mounted on the arbor of the minute hand.

Title: Improvements in or relating to the steering of vehicles
IPC: B62D15/00
Filed: 1945-01-25
Abstract: 588,022. Steering motor vehicles. DUFOUR, L. Jan. 25, 1945, No. 2050. Convention date, Jan. 24, 1944. [Classes 79 (ii) and 79 (v)] A tractor or like vehicle is steered in the normal way up to a wheel deflection of about 25 to 30 degrees, after which further rotation of the steering wheel automatically disconnects the front wheels from the steering mechanism and applies a brake to the driving wheel inside the turn. In Figs. 1 and 2 the front axle 6 is hinged at its centre to the chassis 5 and carries at its ends fixed vertical spindles 7 on which are pivoted arms 8 connected by track rod 23 and actuated by a steering arm 20. The arms 8 carry at their forward ends spindles 10 to which are secured inclined arms 11 carrying the wheels. The spindles 10 carry at their upper ends discs 13 each slotted at 14, the slot normally being engaged by a spring pressed bolt 15 to lock the spindle, whereby normal steering is effected through the steering wheel 27, worm and wheel 26, 25, drop arm 22, rod 24 and steering arm 20, the wheels turning about the spindles 7 disposed vertically over the point of contact between the wheels and the ground. The fixed spindles 7 carry at their upper ends double-sided cams 19 each engaged by a roller 18 on the end of the bolt 15, the cams being so shaped that after a front wheel deflection of 25 to 30 degrees from straight ahead, each roller 18 is caused to withdraw the bolt 15 from the slot 14 in disc 13 and so disconnect the front wheels from the steering gear and allow them to pivot about the spindles 10 castor fashion. At the same time, gears 28, 29 have rotated the arm 31 so far that it contacts arm 32 or 32' freely mounted on spindle 30, and further rotation of the steering wheel and arm applies one or other of the brakes 35, 35<1>, whereby turns of short radius may be effected. In a modified form, Figs. 5 and 9, the front axle 6 projects forwardly at its ends and carries vertical spindles 38 to the bottom ends of which are attached the inclined arms 11 carrying the wheels. Each spindle 38 has secured thereto one half of a dog clutch 40, - the other half 41, which is mounted freely on the spindle 38, being normally kept in engagement with the first half by the spring 43 whereby the wheel responds to -movements of the steering arm 42 to give normal steering. Secured to each end of the axle 6 is a cam 45 engaged by a pair of rollers 44 mounted on the clutch member 41 and arranged so that after the wheels are denected by more than 25 to 30 degrees by the normal steering mechanism, the two halves of the dog clutch are separated, as in Fig. 9, and the wheels left free to follow further turning movements caused by braking. With the arrangement shown in Fig. 5, since the steering head is not vertically over the point of contact between wheel and ground, normal steering movements cause the whole front of the tractor to move sideways.

Abstract: 567,041. Control systems for space discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 10, 1943, No. 2198. Convention date, Feb. 12, 1942. [Class 38 (iv)] Switching control.-Two cooperating thermal members, such as bimetallic strips 21, 22, are connected in the starting circuit of a discharge device, such as a fluorescent lamp 10, having thermionic electrodes 11. When current is applied, a heater 25, in series with the heating circuit of the electrodes 11 and in shunt with the gap between the members 21, 22, heats the member 21 causing it to make contact with member 22 and initiate heating of the electrodes. A heater 26 in series with the heating circuit heats the member 22 to re-open the gap and cause the inductance 14 to initiate the discharge. Failure of the discharge to start is followed by successive repetitions of this cycle, whereby members 21, 22 are progressively deflected in the same direction until the member 22 engages a contact 35 connected to the member 21 to prevent further starting attempts until one switch 16 has been opened or the discharge device has been replaced. The heater 26 remains in circuit and maintains a short-circuit on the heater 25. The construction of the switch is shown in Fig. 2. The heater 25 has preferably a negative temperatureresistance coefficient and is of relatively high resistance, while the heater 26 is of relatively low resistance.
