Abstract: 1406399 Pneumalnc separation LINDEMANN MASCHINENFABRIK GmbH 30 Nov 1973 [12 Dec 1972] 55594/73 Heading B2H An apparatus for separating relatively light non-metallic constituents from pieces of scrap metal obtained from the breaking up of vehicles or other machinery comprises a rotary drum 1 rotatable about is longitudinal axis which is substantially horizontal, a conveyor 6 for feeding the material to be separated into the drum at one of its ends, a number of strips 4 projecting inwards from the inside surface of the drum and extending at an angle to its axis so that, as the drum rotates, material is continuously picked up from the bottom of the drum by the strips and allowed to fall back again and so that the scrap metal portion of the material gradually moves towards an opening at the other end 13 of the drum, and suction means for drawing air through the drum in the opposite direction to the travel of the scrap metal to remove the non-metallic constituents. from the material, the suction means including a suction pipe 7 which has a cross-sectional area smaller than that of the drum and which opens directly into the drum above the conveyor 6, the cross-sectional area of the opening 16 of the suction pipe into the drum being not greater than that of the suction pipe itself. The air suction is generated by a blower 8 which is connected to the pipe 7 via a water separator 9, a pipe 10 and a cyclone separator 11 in which the non-metallic constituents are separated from the air and removed through a preset wheel lock 15. The clean air may be blown into the drum through a tube 18 of semi-circular cross-section which extends through the drum and is located in the half of the drum in which the lifting strips 4 move downwards. The tube is closed at its far end 20 and its flat wall 22 is provided with openings 23 which increase in number towards the closed end. The inwardly extending edges of the strips may be inclined in the forward direction of drum rotation with respect to the drum radii at the junction of the strips with the drum wall, each strip forming a different angle from that formed by an adjacent strip. In another embodiment, Figs 1 and 2 (not shown), the clean air is not blown back into the drum and the opening 16 of the pipe 7 is not eccentrically located in the drum.

Title: Flux gate switches
Inventor: BERNIN VICTOR MAURICE
IPC: G01D5/20
Filed: 1970-11-24
Abstract: 1,271,360. Circuits employing saturable magnetic cores. ILLINOIS TOOL WORKS Inc. 24 Nov., 1970 [24 Nov., 1969], No. 55893/70. Heading H3B. [Also in Division G4] A keyboard switch includes a magnetic core threaded by winding means, and a key-operated flux gate movable between positions where it respectively does and does not divert flux from a permanent magnet away from the core. As disclosed, the thickness of the flux gate is greater than the distance between the permanent magnet and the core. The gate may be U- shaped to straddle the magnet when the key is depressed (say), and may also straddle the core fairly closely, or it may have a flat surface which simply abuts the upper flat surface of the magnet when the key is depressed. A keyboard includes a plurality of such keyboard switches, and a single permanent magnet may be used in common, some cores being adjacent the north pole and some adjacent the south pole. An A.C. source may feed a separate winding on each core, in parallel, via respective resistors, output leads from the resistor-winding junctions each providing a signal which depends on the winding impedance, this depending on whether the position of the flux gate is such that the magnet saturates the core or not. Alternatively, depression of a key to desaturate the respective core may balance an A.C. bridge circuit respective to the core to produce an output signal. Alternatively, an A.C. source may feed a drive winding common to all the cores, output being uncoded from sense windings, one to each core, or coded from sense windings each threading an appropriate combination of cores.

Title: Counterbalancing lid and hinge support
IPC: E05F1/12

Abstract: 1,214,559. Counterbalanced spring hinge. KEYSTONE CONSOLIDATED INDUSTRIES, Inc. 2 Dec., 1968 [23 Feb., 1968], No. 57156/68. Heading E2F. A counterbalancing hinge for a lid pivoted horizontally to a frame, e.g. of a cabinet, comprises a housing 22 mounted on the frame and a lid supporting wing 23 pivoted to the frame via a pin 37, there being provided a U- shaped bracket 55 pivotally mounted on the lid wing about a separate pin 45 whose axis is parallel to but displaced from that of pin 37 and having a central opening 58 therethrough. The housing is of channel shape having side walls 46 and a rear wall, each side wall terminating in an upwardly extending ear 51 supporting the pin 37. A plate 53 having a central opening 54 extends across and is secured adjacent the upper end of the housing. An elongated bolt 62 having an enlarged head 63 extends through the openings 54, 58 into the housing and terminates adjacent its lower end in a threaded portion, a compression spring (78, Fig. 2) encompassing 'the bolt between plate 53 and the threaded portion, there being a retaining washer at each end of the spring and a retaining nut at the threaded end. A retainer 68 abuts the underside of plate 53 and has a central annular projection 69 which is received conformably in opening 54, the projection having a central tapered bore 71. A conical bushing 72 having a radial flange 73 and which is compressible, e.g. by means of a diametrically extending slot 76, is located between washer 77 and the retainer, and its tapered portion 74 is conformably received in tapered bore 71. The bolt is received slidably and engages frictionally in central bore 75 of the bushing. The U-piece may have a central ridge 58 to allow limited relative pivotal movement between it and the bolt. In operation, as the lid is closed, pin 45 moves in an arc about pin 37 lifting the U-piece and the bolt, whereby spring 78 is compressed. Increased pressure of the spring on washer 77 forces bushing 72 further into opening 71, closing slot 76 and increasing the frictional grip on the bolt.

In the embodiment of Fig. 1, the two valves 12, 13 are mounted in a block 14 and have a common diaphragm 15. The valve 12 has a port 26 leading into chamber 16 and a port 25 connected to reservoir 2 and when the treadle valve 5 is operated, pressure in chamber 16 acts to move a valve member 22 off a seating 23 to connect port 25 with a passage 30 and a passage 19 of the second valve 13. When a skid signal is sensed during braking the solenoid valve 34 acts to connect reservoir 2 to a port 33 and the chamber 17 of the valve 13: valve member 22 thereof is moved to connect passage 19 to an outlet port 32 leading to space 10 and close off a throttled exhaust port 29. As shown a balance valve 9 interconnects spaces 6, 10. The embodiment of Fig. 2 includes a third normally closed diaphragm valve 36 in assembly with solenoid valve 34 and second valve 13. The valve 36 has ports 39, 40 connected to spaces 10, 6 respectively via balance valve 9 and a third port 41 connected to treadle valve 5. Valve 12 has an outlet port 37 connected to inlet port 38 of valve 13. When solenoid valve 34 operates, valves 13, 36 are actuated by air from reservoir 2 and via valve 36 spaces 6, 10 are interconnected to reduce the braking force. Air is also supplied to spaces 6, 10 from reservoir 2 via opened valves 12, 13 building up the pressure to its original value.
