Abstract: A heel for footwear has a core composed of felt in sheet or waste fibrous form, or granules of cork, coke or other material, or of coarse particles of wood, e.g., sawdust, impregnated or coated with synthetic resins in paste or liquid form and cut or otherwise formed to shape.  The core is provided with a coating of the same or of a compatible type of synthetic resin.  Where felt sheet material is employed this may be in one sheet, or several superposed cut pieces may be assembled to form the desired shape and, after dipping, coating or impregnating the core with synthetic resin and drying, with partial polymerization in the case of a thermo-setting resin, a coating of the same or a compatible resin is applied and the heel dried.  Alternatively, a covering of synthetic resin in sheet or powder form may be applied in a moulding operation.  A finishing coat of synthetic resin may be then sprayed on.  The resin employed may be one which will react with weak organic acids or chemicals of acid reaction to complete the hardening and polymerization without requiring the use of heat or pressure.

Fire, police, and like alarm systems and apparatus.-In a burglar-alarm system of the kind in which there is a two-position switch 4 by which either alarm contacts 7 or the telephone 10 may bo connected to the exchange wires 13, there are interposed between the contacts and exchange wires signalling-devices designed to give a signal distinguishable from a short or ordinary ring. In the position shown in full lines, the switch 4 connects the terminals 7, 9 of the telephone 10 to the terminals 11, 12 of the exchange lines 13, but in the position shown in dotted lines a crosspiece 42 insulated from the rest of the switch, connects two terminals 40, 41 in the alarm circuit and the terminals 11, 12 are connected to a signalling-device 18. Closure of contacts 7 completes a circuit through the electromagnet 20, armature 21, contact point 25, and terminals 40, 41. On attraction of the armature 21, the falling of a plate 26 on to a contact 17 closes a circuit through the terminals 29 of a motor or other device adapted to drive a signalling-device 18. At the same time, the circuit of the signalling-device 18 is completed to the exchange through a plate 32, which normally rests on an insulating portion of the armature 21. but, when it falls, contacts with the side of the armature. The signalling-device 18 consists of a rotary disc or drum carrying segmental conductors 36 which give a distinctive intermittent signal such as the letter D in the morse code. One of the contacts 38 in the alarm system may 'be on a door, and may be provided with a device by which an authorized person may open the door without giving the alarm.

Abstract: 497,267. Dispensing liquids. BUNN, G. June 15, 1937, No. 16520. [Class 102 (ii)] In apparatus for dispensing liquids, of the type in which the liquid is displaced by another non-miscible liquid of a different specific gravity, and primarily intended for dispensing liquid fuel by means of water pressure, entry of fuel into the water system is prevented by means of a float valve, and entry of water into the fuel pipe is prevented by means of a float valve and by an emergency valve controlled by a water-soluble plug. The container 1 is connected to the water main 4, or to the drain D, by a pipe 2 controlled by a cock 3, and also by a valve 21, operated by a float which sinks in fuel and floats in water. Entry of water into the fuel pipe 5 is prevented by a similar float valve 22, and also by a spring valve 15, which is normally held open by a rod resting on a cartridge containing salt or other water-soluble substance. The valve 3 is operated by a piston 26 in a cylinder 24, which is connected to the water main 4 by valves 25, 26, and'to the drain D by valves 27, 28. All the valves are operated by water distributed by an hydraulic relay 29, which is operated by a movable chamber 10 connected to the container 1 by pipes 8, 9. The chamber 10 sinks when full of water and rises when full of petrol. The valves 26-28 may be replaced by two double-beat valves operated by diaphragms. The hydraulic relay may be replaced by an electrical relay. The container is refilled by means of a pipe 11, and a dip stick can be inserted through a pipe 6. Floating refuse can be removed through a pipe 19 inserted through the pipe 6.

Abstract: 554,820. Boring-heads. WILLETT, V. W., (trading as LUSHINGTON TOOL MANUFACTURING CO.). Nov. 27, 1942, No. 16863. [Class 83 (iii)] The shank 1 of a boring-head, for reception in the machine spindle, is formed with an enlarged end 2 with a transverse slot 4. The tool holder 6 has a flange 7 resting against the ends of the jaws 3 and a flat portion 5 that is a sliding fit between the jaws. A sleeve 8 is a close fit on the part 2 and is secured in place by a set screw 17 passing through one of the jaws 3 and serving also to lock the tool .holder after adjustment by a screw 11 threaded into the holder, passing through the slot 4 and retained in the sleeve 8 by a graduated head 15 and an end 12 retained in place by a cross pin 12a. Semi-cylindrical recesses 3a in the shank co-operate with corresponding recesses in the part 5 to receive pins 9 passing through holes in the sleeve 8 and retained in place by the head of the screw 11. The toolholder 6 may be offset so that when the flat 5 abuts the sleeve at one end of its travel the bore for the tool is coaxial with the shank, this serving as zero position. The graduations are arranged to read in thousandths of an inch. On removal of the pin 12a and end 12 the pins 9 may be withdrawn; if now the screw 17 be slackened to clear the jaw 3 the tool head can be removed as a unit from the shank.

Title: Amplitude filter for the separation of synchronising impulses in television reception
IPC: H04N5/08
Filed: 1937-06-19
Abstract: 497,371. Television receivers. RUDKIN, E. P. June 19, 1937, No. 17086. [Class 40 (iii)] Synchronizing signals are isolated by combining the mixed synchronizing and picture signals with out of-phase picture signals. In Fig. 1 (Comp.), the received signal is demodulated by diode 2a, 5 to produce mixed signals across resistance 4, while diode 2b,5 is biassed by the potential across resistance 34 to produce picture signals only across resistance 26. The two sets of signals are out-of-phase and are applied to the two grids 27, 29 of valve 28 so as to produce synchronizing signals only in its output circuit. The picture signals may be amplified and applied to the suppressor grid of a valve whose control grid is supplied with the mixed signals, Fig. 2 (Comp.) (not shown). In Fig. 3 (Comp.) the diode-triode 64 develops mixed signals across resistance 70, while an anode-bend detector 71 develops picture signals only across resistance 70 in opposite phase, so that only the synchronizing signals appear across resistance 70. A similar circuit uses two diodes, one biassed to produce only the picture signals, Fig. 5 (Comp) (not shown). In Fig. 6 (Comp), the diode 93 produces mixed signals across resistance 94 which are amplified at 95, the valve 95 having its gain reduced during the picture signals by bias derived from resistance 98, (across which picture signals only are developed by valve 106 fed from a diode 105 biassed to produce picture signals only), so that synchronizing signals only appear in its output. The Provisional Specification discloses a circuit operating on a different principle. Mixed signals are applied to the control grid of a pentode 4, Fig. 1 (Prov.), whose suppressor grid is biassed to cut-off. The mixed signals appear in reverse phase in the screen grid circuit and are applied over condenser 13 to the suppressor grid the synchronizing pulses thus allowing anode current to flow.
