Title: Extruding apparatus
IPC: B29C48/06
Filed: 1960-06-17
Abstract: 950,741. Extruding wire coatings. WHITNEY BLAKE CO. June 17, 1960 [June 17, 1959], No. 21386/60. Heading B5A. Extruding apparatus for applying insulating coatings of thermoplastic material to a pair of moving wires comprises means for applying a primary coating of thermoplastic material to each wire, a die assembly which receives the coated wires whilst the primary coatings are still in a plastic condition, a secondary coating chamber in the die assembly for applying a secondary coating of thermoplastic material, and land means in the secondary coating chamber arranged to surround one wire only or to surround one wire and partially surround the other, whereby a secondary coating is applied only to the primary coating of the other wire at least over a portion of its periphery. The secondary coating may be of a different colour to the primary coating and may be in the form of strips or bands for identification purposes. In the embodiment shown in Figs. 1 and 2, wires 10, 12 pass through a mandrel 19 and forwardly extending guide members 40, 42 to a die member 20 where they receive a preliminary coating of a coloured thermoplastic material, e.g. polyethylene, in the chamber 22. A supplementary die assembly 26 is mounted in front of the die member 20 and comprises an extrusion device 28 for extruding the secondary coating, which may be of another thermoplastic material such as coloured polyvinyl chloride, to the wires 10, 12. This secondary thermoplastic material is forced through the feeding tube 30 to a circular chamber 34 which surrounds an inner applying chamber 36 (Fig. 2). A land 38 surrounds the wire 10 while it passes through the chamber 36 and seals it from the coating material. To ensure that the wires 10, 12 leave the die assembly 26 with coatings of the same diameter, the exit apertures 58, 60 are of the same diameter. In an alternative embodiment (Fig. 6), insulated wires with one or more identifying stripes are formed using a supplementary die assembly in which a land 81 seals off both wires from the coating material in the circular chamber 80 with the exception of one or more triangular shaped channels 82 leading to one of the two wires passing through the die assembly. In a further embodiment (Fig. 9), a pair of insulated wires having an inner connecting web and one of the wires being provided with a secondary coating is produced, the supplementary die assembly being modified to provide a channel 104 interconnecting the die chambers 88, 90 to form the web 100 which connects the wires 92, 94, and the secondary coating material being fed via the chamber 80 through a channel 106 so as to cover the entire circumference of the primary coating 98 of the wire 94.
Patent GB-628969-A (GB)
Title: Improvements in or relating to apparatus for echo distance measurement
IPC: G01S1/72
Filed: 1946-07-17
Abstract: 628,969. Echo sounding and distance-measuring apparatus. SUBMARINE SIGNAL CO. July 17, 1946, No. 21392. Convention date, Jan. 5, 1940. [Class 118 (ii)] An echo distance-measurement system comprises means for applying to an indicator or recorder two potentials in series, proportional respectively to the received echo signal and to the time interval being measured. An echo received by a transducer 57, Fig. 9, is amplified and applied to the stylus 9 of a recorder which may be of the type in which the stylus potential burns away a light-coloured insulating layer from a carbon backing sheet. Until the stylus 9 begins to sweep the recording sheet, it is earthed and so maintains a condenser 98 in a discharged state. As soon as the stylus 9 reaches the insulating paper 1 the condenser begins to charge and its potential aids the echo signal. Thus for longer distances, when the echo is weaker, the condenser potential is higher and the resulting potential at the stylus is approximately constant for all distances. The Specification describes a recorder of the above kind in which a motor 7, Fig. 2, drives a shaft 6 and stylus arm 8 on which is mounted a wire stylus 9. The stylus traces an arcuate path over a flat rectangular platen 2 on which rests the carbon-backed recording paper 1, and completes its circular sweep upon a guide member 20 level with the paper. As the stylus 9 crosses the zero line on the paper a cam 26 on the shaft 6 closes contacts to discharge a condenser and so transmit an impulse. In order that greater ranges may be measured the impulse may be transmitted before the stylus reaches the paper by rotating a knob 34 and plate 30 to one of a number of predetermined positions in which the plate 30 may be looked by the engagement of a pin 36 in an aperture thereof. The rotation of the plate 30 alters the position of the transmitting contacts with relation to the cam 26. A zero adjustment may be made by a worm and pinion rotation of the plate 29 to which the plate 30 is locked by the pin 36.

Title: Device for removing stalks from cherries
IPC: A23N15/02
Filed: 1945-08-22
Abstract: 597,543. De-stalking cherries. ETABLISSEMENTS E. MATERNE. Aug. 22, 1945, No. 21477. Convention date, Aug. 22, 1944. [Class 28 (ii)] Stalks are removed from cherries which are received from a hopper K into the recesses D formed in the transverse laths C of the conveyer A. The recesses are then partially closed over on the top by bars E, F slid towards each other by fixed cam rails I, the bars having gaps forming a button-hole opening when closed to trap the cherry and allow the stalk to protrude. At the upper end of the conveyer run, blocks J, on another conveyer, grip the stalks until the divergence of the two conveyers pulls the stalk and cherry apart. The stalks are released into a receptacle Q. The cherries are released into the container P when the bars E, F are slid apart. Fig. 8 shows a modification where the cherries are held in recesses in rods, the top opening being sufficiently closed by the automatic partial rotation of concentric tubes S thereon. Instead of the gripper blocks J, the stalks may be extracted by the oscillation of opening and closing jaws U (Fig. 10, not shown).

Title: Automatic bell-ringing device
IPC: G10K1/34
Filed: 1937-08-07
Abstract: 483,956. Bell - ringing mechanism. BOCHUD, L. Aug. 7, 1937, No. 21809. [Class 13] In an automatic bell-ringing device comprising an electric motor provided with a speed-reduction gear for transmitting the drive of the motor to the rotatable shaft of the bell and an automatic lever-reversing device for intermittently changing the direction of the electric current to effect periodic reversal of the direction of rotation of the motor, the lever-reversing device comprises operated members and associated operating members, some of the members being carried by an extension of the motor shaft, whilst others are mounted on the counter-shaft of the speed reduction gear. The bell is mounted on a shaft carrying a wheel connected by a chain to a wheel 13 fast on the counter-shaft 14 of a reducing gear 18, 18<1> driven from an electric motor 15. The operating circuit and direction of rotation of the motor are controlled by contacts 32, 32<1> and 33, 33<1> engaged by contacts 26, 26<1> carried on an arm 25 rotatably mounted on the counter-shaft 14. Mounted loose on the motor shaft are cam discs 19, 19<1> integral with a gear wheel 20 meshing with a wheel 21 on the shaft 14. The discs 19, 19<1> have ramps 22, 22<1> and 23, 231 respectively which engage with rollers 27, 27<1> carried by arms 24, 24<1> integral with the arm 25. The member 25 is actuated to its circuit closing position by a finger 28 frictionally coupled to the motor shaft by discs 29, 29<1> and a spring 8. The arm 25 is normally biassed by a spring 31 to close the contacts 32, 32<1> and during the initial motion of the bell the finger 28 moves to the right. The inertia of the bell overcomes the torque of the motor and reverses its swing causing the finger 28 to rotate in an anticlockwise direction and to move the arm 25 to close contacts 33, 33<1>. These movements continue until the bell reaches a predetermined amplitude denoted by alpha in Fig. 7 when ramp 22<1> on disc 19 engages the roller 27 on arm 24 and moves the arm 25 together with the finger 28 to a central position thus opening the motor circuit. When on the return swing the bell again reaches the position A, the arms 24, 24<1> are not restrained bv the ramps 22<1>, 23<1> and the finger 28 moves the switch-arm to close contacts 33, 33<1> completing the circuit for the reversed drive. When the bell reaches the position B on its upward swing. cam 23 on disc 19<1> engages roller 271 on arm 241 and cam 22 on disc 19 engages roller 27 to move the contact member to its central position, and to hold the circuit open until the bell reaches B on its downward swing. In a modification. Figs. 4, 5 (not shown), the arm 25 is formed with a loop engaging the countershaft 14 and is integrally formed with arms corresponding to the arms 24, 24<1> shown in Fig. 2, and is actuated to its contact-making positions by forked projections carried by a ring frictionally mounted in a recess in a wheel keyed to the shaft 14. The upper end of the arm 25 is biassed to one or other of its contactclosing positions by a spring and lever arrangement.

Abstract: 1,059,855. Electrical conduit; two-part couplings; distribution arrangements. A. S. VAUSE. July 5; 1965 [May 27, 1964], No. 21832/64. Headings H2C and H2E. In a casing for electric wiring with an outer sheath S containing several conduits C (in the example shown three), each of which holds one or more conductors, the conduits are offset relative to one another in two directions at right angles to one another. Identification of the conductors is then facilitated by the position of the conduits in which they are located. Sections of casing may be joined at any angle by cutting the sheath and conduits so that when the parts are fitted together corresponding conduits are in communication. For example in the branch 2 the conduits containing conductors 7 and 10 and 6 and 9 extend beyond the cut end of the outer sheath and that which carries conductors 5 and 8 is flush with it. In the arrangement of Fig. 4 (not shown) hollow trapezoidal conductors fit trapezoidal conduits. Connector pins with matching ends can be introduced into their interiors through longitudinal slots in the sheath and conduits and turned through 90 degrees to lock in position. The slots may be omitted if the pins are formed with blade-like ends that can cut through the sheath and conduits. The surface of the conduit may be treated with an impact adhesive.

Title: Improvements in or relating to thermionic generators
IPC: H03H7/38
Filed: 1934-07-26
Abstract: 425,815. Valve generating circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. July 26, 1934, No. 21891. Convention date, Sept. 6, 1933. [Class 40 (v)] The electrodes of a thermionic short-wave generator, such as a split-anode magnetron, are connected to the oscillatory circuit through a network comprising shunt inductances separated by series condensers, with the object of compensating the shunt capacities of the electrodes and their leads, and the series inductance of the leads. Fig. 2 shows a magnetron oscillator with anodes 2, 4, connected by leads 3, 5 to the anode terminals 7, 9. Interposed between the terminals 7, 9 and the parallel-wire tuned circuit 8 is a quadripole comprising shunt inductances 12, 16 and series capacities 14. Inductance 12 is adjusted to give parallel resonance with the capacity between the terminals 7, 9. Condensers 14 are arranged to give series resonance with the inductance of the leads 3, 5. Inductance 16 is adjusted to give parallel resonance with the capacity between the electrodes 2, 4. With the reactance of the electrodes and leads thus compensated, the positive resistance of the external circuit may be made substantially equal to the internal negative resistance of the discharge tube. In a modification, Fig. 3, the inductance coils 12, 16 are replaced by parallel-wire circuits.
