Abstract: 659,052. Moulding shoes. VOL CREPE, Ltd., and WOOLLEY, J. E. April 5, 1946, No. 10540. [Class 87 (ii)] [Also in Group VII] A shoe having a sole made wholly of a thermoplastic synthetic resin is made by lasting an upper of leather, felt or reinforced plastic sheeting on a metal last D, then applying the upper to the resin A in a mould B on a hot plate F<SP>1</SP>. Pressure is applied by the head F of a hydraulic press, to cause the resin to spew up around the lower edges of the upper. When the upper consists of straps C<SP>1</SP> a rim B' may be provided to prevent the spewing up of material except around the ends of the straps. The downward movement of the last may be limited by distance pieces F<SP>2</SP>. Pressure is transmitted to the toe of the last through a member E. In a modification, Fig. 4, the sole material may be injected into the mould through a nozzle G, the last being forced up until it engages a fixed plate F<SP>2</SP>. In a further modification the sole material may be plasticized and then poured into the mould. The bottom of the upper may also be coated with the paste. The last with the upper is then placed in the mould and the mould heated electrically to 140‹C. which causes the paste to gell. Pressure is then applied, after which the mould is cooled. An upper may be formed on the last, by providing recesses on the last, heating it, and then spraying a plastic paste on to the last. A sole may then be formed on the upper as described, to form an all plastic shoe. Specification 582,431 is referred to.

Title: Automatic lighter with elongated flint
IPC: F23Q2/08
Filed: 1946-04-11
Abstract: 616,293. Frictional igniters. LEON, J., and BORTHAYRE, A. April 11, 1946, No. 11191. Convention date, July 11, 1945. [Class 75 (iii)] On the opening movement of the cover of the casing of a lighter the flint is advanced against a friction surface by means connected with the cover. On moving the cover 8 to the left as seen in Fig. 1, a notch 15 engages a tongue 29 of a blade spring 26 which partly surrounds, at its upper end, a spindle 25 connecting a pair of parallel racks 24 and so moves the spring and racks 24 outwardly. At the same time the spring tongue of the member 12, which guides the cover in flanges 13, rotates a nut 21 in which the flint 4 is threaded to raise the latter, the pressure of the flint also raising the flint wheel 17 and the fork 19 in which it is mounted until the spring fork which is upwardly bent disengages the member 12 from the nut 21. The flint 4 is of substantially square cross section and has screw threads at the four angles to engage the nut 21. As the cover 8 is moved further to the left, the spring 26 recedes and the tongue 29 passes under the notch 15, a spring 30 which has been gradually compressed during the motion then expanding to return the racks 24 which rotate the wheel 16 to ignite the wick the cap 9 having opened in the initial stages of the motion when freed from the action of the upwardly bent part 23 of the fork 19. The lighter may be kept in this position by exerting a vertical upward pressure which causes the ends of the member 12 to engage in grooves 33, or the cover may be released to allow the parts to return under the action of the spring 30. The reservoir comprises a hollow part 1 having a large filling opening of at least 27 mm. diameter surrounded by a groove 2 which may be fitted with plastic material so as to form a liquidtight joint with a casing 3 which surrounds the reservoir on three sides and is held to it by a U- shaped strap 31 in the manner of a book-clasp, the strap passing through a groove under the blade spring 26. A channel may be provided in the wall of the reservoir to receive a propelling or other pencil, and the surface of the lighter may be ground, coated or provided with removable sheets to serve as a writing surface. In a modification, the flint may be urged by a helical spring which surrounds the flint and acts on a plate forming a seat for the flint, the advancement of the plate being effected automatically by movement of the cover.

Title: Improvements in the arrangements for the supply of power to wireless transmitters
IPC: H03F1/54
Filed: 1923-04-26
Abstract: 214,089. Edgeworth, K. E. April 26, 1923. Thermionic generators.-Wireless transmitters in which the source of power is situated at a dis. tance from the oscillation generator are provided with switching-means adjacent to the power source but adapted to be controlled from the oscillator, said switching means making and breaking the connection between the power source and the high-tension leads. Thus, when the oscillator is not working there are no live leads in its neighbourhood. As shown in the Figure, the valve transmitter 13 is situated at a distance from the high-tension source 1, 2 and the low-tension source 3, 4. The valve is set in action by closing a switch 12 in the filament circuit, which is connected through a cable 10 and relay 9 to the low-tension supply 3, 4. Thus when the switch 12 is closed the relay 9 is energized, closing the switch 5 and connecting the high-tension mains 1, 2 to the supply cable 8. When the switch 12 is opened, relay 9 is de-energized and releases its armature 5, thus disconnecting the cable 8 from the high-tension supply. The relay 9 may be arranged on the power switchboard. In addition to protecting the operator from accidental contact with the H.T. supply, the arrangement prevents interference with the action of a receiver in the intervals of non- transmission.
