Title: Improvements in or relating to lasting machines
IPC: A43D21/12
Filed: 1938-05-19
Abstract: 514,959. Lasting-machines. UNITED SHOE MACHINERY CORPORATION. May 19, 1938, No. 14898. Convention date, May 21, 1937. [Class 17 (i)] Relates to machines of the kind described in Specification 473,197. wherein an end-lasting machine has a h o 1 d - down engaging the shoe bottom to determine the position of the shoe relatively to the plane of the wipers, and consists in operator controlled means for effecting a quick adjustment of the hold-down from normal position to another to meet special conditions, and automatic means for returning the mechanism to normal position at the completion of the machine cycle. If, for example, a heel end stiffener has been improperly positioned it may be desirable to depress the shoe so that the wipers exert less pressure during the overwipe. As described in the prior Specification, the hold-down 8 is raised and lowered by a rack 12 meshing with a pinion 14 on a shaft provided with a spiral gear 18 engaging teeth on a slide 20 actuated by a cam 30, a spring 32 urging the slide in a direction to lower the holddown to a limit determined by a lug 34 engaging a spring plunger carried by a lever 40. To allow the hold-down to depress a particular shoe farther than usual, a plunger 74 is provided with a head 76 adapted to be depressed by the operator to rock a lever 62 which engages the slide 20 by a bolt 66 also carrying a latch 82 co-operating with steps on a tongue 50 projecting into a bifurcation of the slide. A spring 56 urges the slide to the left and a pin 52 and slot allow lost motion between the slide and its camoperated extension. A spring plunger 88 urges the latch counter-clockwise, and a stop 90 cooperates with a tail of the latch. As shown, the mechanism is set for normal shoes. If the next shoe to be lasted necessitates the lower position of the hold-down, the operator depresses the plunger 76 before starting the machine. Rocking of the levers 62 retracts the slide 20 and causes the latch 82 to engage the next lower step 86. The hold-down thus takes a lower position during the whole power operation of the machine. At the conclusion of the cycle, when the hold-down is operated to depress the shoe away from the wipers, the latch is repositioned by the stop 90 engaging its tail 92.

Title: Light-projecting dummy cartridge for shot guns
IPC: F41A33/02
Filed: 1929-05-13
Abstract: 333,540. Purdey & Sons, Ltd., J., and Lawrence, E. C. May 13, 1929. Teaching shooting.-A dummy cartridge, of the kind which, on simulated firing, projects a beam of light through the barrel of the gun on to the spot at which the gun is directed, is entirely selfcontained. The device comprises an outer tube 1, Fig. 1, which closely fits the bore of the gun and contains, at its forward end, a lens 2. An inner tube 3, Fig. 2, fits into the outer tube and is secured thereto by a bayonet-joint 4. The inner tube contains dry cells 6 and an electric light bulb 5. An extension tube 7, resembling a cartridge in form and size, contains a contact-piece 8 and a spring-controlled sleeve 11 in which moves a contact-making pin 13 which is also spring- pressed rearwardly. On closing the breech of the gun, the sleeve 11 and the pin 13 are pushed inwards until the contact-piece 8 and the pin 13 are nearly touching. When the firing operation is performed, the gun striker causes the pin and contact-piece to touch and the circuit between the bulb and batteries is closed. The lens 2 may be placed eccentrically with respect to the outer tube. In a modification, the outer tube is dispensed with and provision is made in the tube 3 for holding the lens.

Title: Improvements in or relating to apparatus for sealing collapsible tubular containers
IPC: B21D51/36
Filed: 1942-10-24
Abstract: 560,947. Electricity supply systems. BRUUN, O. J. Oct. 24, 1942, No. 14953. [Class 38 (iv)] [Also in Group XVII] Apparatus for sealing the filling-ends of collapsable tubular containers comprises electrically heated jaws for simultaneously squeezing together and heating the end walls of the containers, and control means for regulating the temperature of the jaws, the control means being situated at a distance from the heating device. The apparatus is particularly suitable for applying to any type of tube-sealing machine with unheated jaws. The jaws 1, 2, Fig. 1, each consist of a plate with an integral extension 3 on which is mounted a heating coil 4 with a cover 5. The jaws are attached to their arms 6 by springs 9 to allow the jaw surfaces to align correctly when they are gripping a tube end. The coils 4 are energized intermittently from the mains L<SP>1</SP>, L<SP>2</SP>, Fig. 3, under the combined control of an energy regulator 10 and a hot wire vacuum switch 11. The regulator 10 comprises a stationary contact 12 and a movable contact 13 which is mounted on a bimetal strip 14 surrounded by a heating coil 15. Normally the contact 13 engages the contact 12 but moves away from it as the strip 14 is heated, the time of disengagement of the contacts being regulated by an adjustable screw that controls the position of the contact 12. The switch 11 is enclosed in an evacuated envelope and comprises a stationary contact 20 and a movable contact 21 which is mounted on a thin rod 22 adapted to be heated by a coil 23. Normally the contact 21 is out of engagement with the contact 20, but when the rod 22 is heated it elongates and closes the contacts. The coils 4 and the members 10, 11 are connected as shown, and a pilot light 33.is provided to indicate when the coils are energized. In operation, when the main switch 34 is closed, the'coils 4 and the heating coil 15 are not energized, but the coil 23 is energized and heats the rod 22. After a time, the contacts 20, 21 close and the coils 4 and the heater 15 are both energized, and after an interval the contacts 12, 13 separate leaving the heater 15 and the coils 4 energized. After a further interval, the contacts 20, 21 separate and disenergize the coils 4 and the coil 15, and the cycle is then repeated. The relative lengths of the periods during which the coils 4 are energized and disenergized are regulated by adjusting the screw that controls the position of the contact 12. A thermometer 36, Fig. 1, may be provided on one of the jaws and connected to an indicator which may be arranged, with the parts 10, 11, the pilot light, and the adjusting screw of the contact 12, on. a panel remote from the heating coils 4. In a modification, the switch 11 may be dispensed with or it may be replaced by a normally open relay of the instantaneousresponse type.

Title: Improvements relating to demodulating apparatus for pulse signalling systems
IPC: H03K9/00
Filed: 1943-09-17
Abstract: 579,565. Pulse modulation. COSSOR, Ltd., A. C., and BELL, D. A. Sept. 17, 1943, No. 15305. [Class 40 (v)] A demodulator, for signals conveyed by a series of identical pulses modulated as to their phase or frequency, comprises means for mixing the received pulses with a saw-tooth oscillation of the same mean frequency thereby producing an output which varies with the phase relationship of the components, and represents the signal or modulation. The frequency or phase of the saw-tooth oscillation may vary with that of the incoming pulses and to a nearly equal degree. As shown, the pulses are derived by rectification of a received carrier in the valve 3 and are applied from the anode of that valve to the mid-point of the secondary coil of a transformer 27, the primary of which is fed from a saw-tooth generator 35 of the blocking oscillator type. The mixed oscillations pass through balanced diode rectifiers 25, 26 to load resistances 28, 29 and an output transformer 32 feeding a signal amplifier 33 and reproducer 34. The frequency or phase of the saw-tooth oscillator may be made to follow that of the received pulses by a connection across the load resistances 28, 29 into the grid circuit of the valve 35., Condensers 30, 31 byepass the pulse frequency. In a modification, Fig. 3 (not shown), the received pulses are broadened by a condenser-resistance combination in the anode circuit of the valve 3 ; and the mixing of the pulses with the saw-tooth oscillation is effected by applying them to separate control grids of a mixer valve of the double-control type.
