Abstract: 1,130,924. Injection moulding machines for pipe junctions. ELLISTOWN PIPES Ltd. 19 Aug., 1966 [19 Aug., 1965], No. 35590/65. Heading B5A. A method of moulding branch pipe integrally with a main pipe comprises closing a die assembly 10 and raising it into engagement with an extrusion nozzle 2, raising a base 12 to locate a main core 14 inside the assembly, then locating a branch core 16 by means of a fluid cylinder device 19 in a branch part of the assembly 10 and abutting the core (14), then extruding a mixture of clay and grog into the mould formed by the cores and assembly 10 until a flashing shows around blocks (15), 17. Extrusion is ceased, the die assembly opened horizontally along its parting line (11) (Figs. 1, 3) and the branch core 16 withdrawn, rollers 20 on the block 17 running on tracks (21) (Fig. 4) ensuring that the core 16 remains correctly aligned with core (14). Extrusion is recommenced, base 12 being simultaneously lowered at the same rate to form the main pipe to the required length. During this extrusion, no pressure is used in the fluid device (not shown) operating base 12 which is thereby balanced and moves vertically downwardly solely due to the extrusion force. The pipe is removed from the machine by either stopping extrusion and continuing lowering core 14 until free of the pipe which is then severed from the nozzle 2, or stopping both extrusion and lowering, severing the pipe from the nozzle, and lowering the base and core (14) sufficiently to lift the formed pipe therefrom. One or more branch pipes may be formed either obliquely or perpendicularly to the main pipe. In every embodiment the parting line (11) of the die assembly lies in a plane passing through and parallel to the axis of both the main and branch pipes.

Title: Improvements in or relating to Bobbin Case Openers for Rotating Looptaker Lockstitch Sewing Machines.
IPC: D05B57/14
Filed: 1968-07-29
Abstract: 1,164,258. Sewing machines. G. M. PFAFF A.G. 29 July, 1968 [31 July, 1967], No.35991/ 68. Heading D1G. In a sewing machine comprising a rotary hook rotatable at a whole number multiple of each stitch formation, and a bobbin case opener adapted to rotate the bobbin case oppositely to the direction of rotary hook rotation for opening a thread-escape gap, the bobbin case opener is operatively connected to two driving eccentrics, or equivalent mechanical means, one of which rotates synchronously with the rotary hook and the other of which rotates with a reduced whole number ratio thereto. A bed shaft 9, rotating synchronously with the arm shaft, is coupled by gearing 21, 22 to a vertical axis hook body 18 for rotating the latter at twice the speed of shaft 9. The driven gear 21 has a hollow shaft extension which is journalled in the machine frame and receives the lower end of a hollow shaft (17), Fig. 3, frictionally coupled to gear 21 by the head of an internally screwed bush (19) projecting upwardly into shaft (17) to engage a downwardly-projecting screwed stud (20). Upwardlyprojecting lugs (32) on shaft (17) enter apertures (33) in body 18 to couple the latter to shaft (17): A bobbin case 24; journalled in body 18, has a rotation-restraining lug 28 engaged in a notch 30 in the throat plate 29. An eccentric (31) on shaft (17) is embraced by a strap 35 rigid with a finger 36 adapted to cooperate with a lug 37 on bobbin case 24 for turning the latter to open a thread-escape gap between lug 28 and notch 30. An arm 39, projecting from strap 35, is connected by a pivotal link 41 to a bracket 44 rigid with a rod 45 slidable in the machine frame parallel to the direction V of work feed. A bracket 46, rigid with rod 45, is pivotally connected to a pitman 48 embracing an eccentric 49 on shaft 9. The arrangement is thereby such that during the thread loop-manipulating rotation of body 18, a point on finger 36 moves from a position O along a path A to engage lug 37 at a position 4 comparatively slowly along a gentle curve and disengages from lugs 37 at a position 6 comparatively quickly along a sharp curve, and then traces a closed curve D, separated from lug 37, during the succeeding idle rotation of body 18. In a modification, Fig. 4, eccentric 49 is carried by a vertical shaft driven by 1:1 gearing from shaft 9, and is embraced by a pitman pivotally connected to arm 39. In a further modification, Fig. 6, eccentric 49 is carried by a vertical shaft coaxial with the rotary axis of looptaker body 18 and driven by 1:1 gearing from shaft 9, and is embraced by a pitman pivotally connected to a crank arm on the lower end of a vertical shaft, the upper end of which carries a crank arm coupled by a pivotal link to arm 39. In a final modification, Fig. 8, eccentric 49 is carried by a vertical shaft driven by 1:1 gearing from shaft 9, and is embraced by a pitman, the extended arm of which is pivoted intermediately to arm 39 and carries at its free end the finger 36.

Abstract: 737,079. Coin-freed apparatus. NATIONAL REJECTORS, Inc. Dec. 30, 1953 [Aug. 21, 1953], No. 36173/53. Class 27. Coin-freeing mechanism, requiring the insertion of more than two coins and particularly adapted for vending apparatus, has coin counting means comprising a rotatable wheel 64 with a number of coin intercepting surfaces 70 engaged by coins in a passageway 58 and with cam surfaces 68 for operating the arm 48 of an electrical switch 46, the number of intercepting surfaces 70 being a multiple of the number of cam surfaces 68 according to the number of coins required for each actuation; as shown in Fig. 1, the wheel has four surfaces 70 and two surfaces 68 and requires two coins for each actuation. The arm 48 extends into the coin passageway ahead of the surfaces 70 and is raised by the first coin sufficiently to withdraw a detent portion 50 from an opening 72 in the wheel so that the coin can rotate the wheel sufficiently for the detent to engage a following opening 72 and prevent overshooting. The second coin will again raise the detent and rotate the wheel to cause one cam surface to engage the detent and move the arm 48 sufficiently to actuate the switch 46, momentarily, the detent finally engaging another opening 72. The openings 72 following a cam surface are larger than the others to ensure that the detent, falling from a raised position, will engage properly. Each inserted coin is first tested by a slug rejector 20, pivoted sizing and weighing cradle 22 and permanent magnet 26, and accepted coins are directed to the passageway 58 along a runway 28 having a movable portion 32. When the second coin has actuated the switch 46, an electromagnet 36 is de-energized and a spring 40 lowers the portion 32 of the runway so that further coins fall into a rejected coin shoot 42. At the same time, a holding circuit is established to energize an electromagnet 74 and a stop 80 is withdrawn from a passageway in the slug rejector so that a third coin, which is of a different type and is required to initiate a vending cycle, is directed by the slug rejector 20 into a second passageway where it engages a lever 100 and actuates a switch 94. The switch 94 energizes a relay that starts the vending cycle and de-energizes the electromagnet 74 to restore the stop 80. At the end of the cycle, a delivery switch is opened and the relay is de-energized, thus energizing the electromagnet 36 and raising the portion 32 into continuation of the runway 28. The electromagnet 36 may be arranged in the circuit so that it remains raised except when the vending apparatus is de-energized or there is a power failure.

[Also in Group XXIII] A control system for a glass-washing machine which washes with detergent and then rinses with hot and cold water consecutively includes a booster tank 18 for hot water provided with a heater 29 and a thermostat 36 with contacts 29a and 36a. When the water reaches the desired temperature of 190‹ F. contacts 36a close and light up pilot light 35 to show that the machine is ready for operation. Momentary closure of starter switch 34 completes a circuit through relay 37 closing contacts 38 and 39, the former completing a circuit to timer motor 26a while the latter completes a holding circuit via contacts 26c and also energizes detergent supply solenoid 48. After a suitable period, timer 26a opens contacts 26c and closes contacts 26b, de-energizing solenoids 37 and 38, the motor 26a being kept running by normally closed contacts 40. The closure of contacts 27b energizes time lag solenoid 27a which closes contacts 41 for a controlled period during which solenoid 19a is energized and operates the hot water valve, while the energization of solenoid 40a opens contacts 40 and thus prevents the timer from moving while hot water is being supplied. At the end of the controlled period contacts 41 open and the timer motor continues to operate until it is interrupted again by the supply of hot water for rinsing. Contacts 14a operated by the timing cams control the impeller motor and the dump valve 31a so that the motor is stopped when the valve is open. The supply of cold water is controlled by contacts 20b and solenoid 20a. Specification 875,117 is referred to.

A circuit for delaying a pulse train or a pulse of alternating current at terminal 2 comprises a transistor 6 having a capacitor 4 connected in series with the input circuit and a discharge path comprising a diode 3 and resistor 5, an alternating or pulse voltage in anti-phase to the input voltage being supplied to the collector and to the discharge path. As described, transistor 6 is normally conductive during positive half-cycles at terminal 1 so that the output at 7 is substantially zero. When an alternating current signal is received at terminal 2, it is rectified at 11 and charges capacitor 4 so that transistor 6 becomes non-conductive for the duration of the signal. The conduction of transistor 6 is delayed after the end of the signal at terminal 2 whilst capacitor 4 is discharging via diode 3 and resistor 5. The current waveform in the magnetic amplifier load 8 is therefore a train of pulses commencing with the first negative half-cycle at terminal 2 and terminating at a time (adjustable by variable resistor 5) after the termination of signals at 2. The temperature coefficient of the diode 3 should be arranged to compensate for that of the base/emitter junction of transistor 6.
