Abstract: 496,053. Wireless receiving sets. BEATTY, W. A. May 26, 1937, No. 14606. [Class 40 (v)] A combined radio-receiver and clock has the clock face provided with an aperture through which the tuning pointer projects, means being provided attached to the clock or receiver parts for obscuring the aperture without interfering with the hand or pointer movements. In one arrangement, Fig. 2, a disc 13 attached to and spaced from the clock face 10 obscures the aperture 12 for the tuning pointer. In Figs. 6 and 7, the tuning indicator operated by pulley 22 is formed as a pointer disc 18 and extension 21, the clock hand spindles 19, 20 projecting through the part 18. The time hands of the clock can be enlarged to cover the aperture, or the disc member can be mounted on the clock hand spindles.

Abstract: 1523229 Recovering cable components HANDELSMAATSCHAPPIJ OSBO NV 2 Dec 1976 [8 Dec 1975] 50365/76 Heading B2H [Also in Division B3] The component materials of a scrap cable are recovered by cutting the cable transversely and along its length and by subsequently sorting out the portions of materials which have been reduced in size and separated from one another by the cutting operation. As shown diagrammatically in Fig. 1, the cable is first cut transversely at a station 6 into pieces of given length and the cut pieces are split longitudinally by urging them by means of a vertically reciprocatory pushing member 12, Fig. 2, through a convergent opening 8 of a die against a stationary cutter 11. The loose portions of the cable are then cleaned in a degreasing and drying device 14 and delivered by a belt 17 and an air sluice 19, Fig. 4, to a tubular upwardair-current separator 18 in which lightweight materials, e.g. paper and hamp, are conducted upwardly to an outlet 30 whilst metal parts drop down on to a conveyor belt 21 above which is situated a belt-type magnetic separator 22 which separates out iron particles. The non-magnetisable metal parts are delivered by the belt 21 to a vibratory sieving device 25 in which a bar grid of T-section profiles serves to retain lead plates of the cable sheath and to pass elongate wire-shaped parts on to a sieve which passes naked wire and retains insulation-covered wire which is delivered to a hammer mill 29 where the wire is separated from the insulation and both materials are recycled.

The assembly is unwound and passed out of the tank via a nozzle 12 to a heating duct at 50 to 100‹C, where the solvent is driven off and hardening commetices, and rewound onto a grooved drum. After hardening, further heat treatment at 150‹C for several hours improves the dimensional stability of the product.

Title: Filters for the removal of atomic or molecular particles from a flowing gas
IPC: B01J19/00
Filed: 1977-12-07
Abstract: The adsorption/absorption filter serves to remove a substance present as atomic or molecular particles from a flowing gas. Its filter material has as high a retaining power for said particles as possible. The filter comprises parallel tubes (1) surrounded by an outer tube (2). The tubes of the filter have the gas to be purified flowing both through them on the inside and around them on the outside. The length l and the hydraulic diameter deff of the filter are dimensioned in such a way that, with a predetermined pressure loss  DELTA p and a predetermined filter volume, the product of l DIVIDED deff . St'  where     deff = 4V0 DIVIDED F is the hydraulic diameter in cm,   l is the length of the filter material in cm, Vo is the cavity volume in cm<3> left inside the sheathing in the region of the length l after fitting the filter material, F is the surface of the filter material in cm<2> wetted by the gas,    St' = h DIVIDED v is the second Stanton number,   h is the mass transfer coefficient in cm/sec,   v is the velocity of flow of the gas in cm/sec,  is a maximum.

Such a filter is therefore used in the main gas stream of a gas-cooled nuclear reactor. <IMAGE>

Closing of a thermostat switch THS feeds A.C. power to the pilot valve to open it and to the ignition circuit through normally closed switch 21A such that a pilot flame is lit and main burner valve consequently opened. If the flame or a circuit component fails then the main burner valve is closed and ignition of a pilot flame is again attempted. In a second embodiment the relay 21 is replaced by the solenoid of the main burner valve and the ignition circuit is arranged to cut itself off when a flame is lit and to attempt relighting if the flame goes out. A third embodiment is similar to the second except that a D.C. power supply is used and an inverter and a manually resettable warp switch are included in the circuit. A fourth embodiment is similar to the first but uses D.C. power with an inverter and a warp switch included as in the third embodiment.
