Abstract: 1,196,838. Sorting scrap material. EISEN UND METALL A.G. 11 June, 1968 [12 June, 1967; 13 June, 1967; 3 May, 1968], No. 27621/ 68. Heading B2H. The components of insulated cable or wire scrap are separated by fragmenting the scrap by means of a smashing or cutting device and continuously conveying the fragmented scrap to a gravity separator to separate the metallic from the non-metallic component of the scrap, the rate of movement of the fragmented scrap between the smashing or cutting device and the separator being adjusted so that substantially no accumulation or storage of the fragmented scrap occurs between the device and the separator. As shown, the scrap is fed to a smashing or cutting device 2, such as a hammer or milling cutter, by means of an endless conveyor 1. The fragmented scrap is discharged onto an endless conveyor 4 whereby it is dropped into a gravity separator 6. Pneumatic and magnetic devices 3, 4 arranged above the conveyor 4 serve to separate, respectively, particles of light material, e.g. dust and paper, and ferrous components from the scrap. The separator 6 contains a liquid having, for example, a density of 2 grams per c.c., so that the non-metallic components of the scrap, e.g. plastics materials, are floated - off while the remaining (non-ferrous) metallic components sink and are removed from the separator by a conveyor therein which carries the components upwardly and discharge them into a further gravity separator 7. The floated-off non-metallic components are discharged on to a sieve 12 for washing and subsequent discharge into a conveyor 13. The separator 7 contains a liquid having, for example, a density of 2.8 to 3 grams per c.c., so that light metal components, e.g. of aluminium, are floated off and discharged into a sieve 10 for washing and subsequent discharge onto a conveyor 11, while the heavy metal components, e.g. of copper and lead, sink and are discharged by a conveyor onto a sieve 8 for washing and subsequent discharge onto a conveyor 9. In a modification, Fig. 2 (not shown), a further smashing or cutting device (14), is interposed between the discharge end of the conveyor 4 and the separator 6 and is preferably equipped with rotary blades for shearing the fragmented scrap into smaller sections.

Title: An electrically operated liquid fuel burning device
IPC: F23N5/08
Filed: 1927-10-21
Abstract: 281,619. McCabe, I. E. Dec. 6, 1926, [Convention date]. Electrically controlling fuel and air supplies.- The electric circuit to a motor M supplying liquid :fuel and air to a burner device in a domestic or other heater H includes a safety control device which is shunted when the burner is alight by a circuit closed by a switch actuated by the light from the burner flame. The motor circuit also includes a room thermostat T, a pressure or temperature actuated control C on the heater H, and a hand-operated switch S. The safety control device comprises a casing 1 containing a pivoted mercury tube switch 8 normally held in the raised position by a bimetallic strip 10. When the switch S is closed the current to the motor passes through flexible leads 6, 7 and the switch 8 to a post 3 and then divides, part going through a resistance coil 16 surrounding the bimetallic strip 10 and part through a lead 23 and a variable resistance 19 to a binding post 18. From the post 19 the current passes through a resistance coil 17 surrounding a bimetallic strip 15 to a binding post 5 and then to the motor M. The bimetallic strip 15 normally supports a mercury switch 12 in a position to close the circuit to an ignition coil I for the burner, but, this circuit is broken when the strip becomes heated by the current passing through the coil 17. If ignition of the burner is effected a light-actuated switch in a casing L closes a circuit Q to shunt the heating coil 16 and the variable resistance 19. If ignition of the burner is not effected, or if ignition subsequently fails, the heat generated in the coil 16 causes the bimetallic strip 10 to release the switch 8, so that it is swung by a weight 9 about its pivot and breaks the motor circuit. The light actuated switch comprises a bulb 24 formed of a medium which absorbs visible light rays and a transparent bulb 25, these bulbs being connected by a restricted passage 26 containing mercury or other fluid conductor. When the burner is alight the gas within the bulb 24 expands and causes the mercury seal to rise in the bulb 25 and close the circuit between the terminals therein. The casing L of the light-actuated switch may surround a: slot in the lower part of the draft supply pipe D, so that the bulbs are situated adjacent the fuel discharge pipe 28 in the path of the air current. Alternatively, the light-actuated switch may be arranged as shown in Fig. 5 in a casing P having a restricted opening 30 to permit the light to enter from the heater H. Preferably, air is diverted by a deflector 33 from the draft pipe D through the casing P into the heater H. A removable screen or screens 34, 35 of a medium adapted to absorb the invisible rays of the spectrum may be arranged in front of the bulbs 24, 25. Orifices 36 in the casing ventilate the space between the screens. Specification 277,344 is referred to.
