Title: Separation of materials
IPC: G01R33/12
Filed: 1971-04-19
Abstract: 1323511 Locating magnetic material AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE and CIMENTS LAFARGE 19 April 1971 [6 Feb 1970(2)] 21147/71 Heading G1N Materials having an induced or residual magnetic field are separated by continuously relatively moving said materials and at least one sensor responsive to magnetic fields and using signals produced by the sensor to control material separating means. In a first embodiment, Figs. 1 and 6 for screening crushed ore, lumps of ore are channelled by guides 4 into rows running along a conveyor belt 1. A demagnetizing station 6 is followed successively by a magnetizing station 7 having permanent magnets and a sensor station 8 comprising, Fig. 6, a plurality of coils 17 in line with the rows of lumps and positioned below the belt 1. Additional coils 18 above the belt 1 are wired so that induced currents are summed whereas relatively remote coils 20 are wired in opposition, the arrangement being such that external magnetic field changes have no induction effect. The coils are housed in a robust housing 19 to provide protection from the effects of mechanical vibration. Signals from the individual sensors are amplified, integrated during the time that each lump is adjacent a sensor, compared with a threshold value and, where the threshold is exceeded, fed to a delay line (e.g. an endless magnetic tape loop) synchronized with the movement of the belt, so that separating means 11 may be operated at the precise moment that the relevant lump 5 arrives thereat. As exemplified Figs. 11 and 12 (not shown) the separating means comprises a pneumatic arrangement for directing blasts of air onto selected lumps as they fall off the end of the conveyor belt to modify their trajectory. A mechanical pusher may be used instead. Pockets may be provided in the belt 1 for the lumps 5. In a second embodiment, Fig. 9, the fixed coils and integrator are replaced by rotary coils 31, 34, 35 rotating on shafts 32, 36 and 37 in a housing 40. This embodiment is especially suitable for screening powdered ore spread uniformly over the conveyor belt. In a third embodiment, Fig. 17, a self compensating sensor comprises two identical coils 47a, 47b on two identical core portions 48a, 48b of a high permeability alloy with two identical air gaps 49a, 49b. A differential amplifier 50, Fig. 13 (not shown) with a fine adjustment 51 to compensate for any lack of symmetry is provided to carry the signal from the windings. The arrangement enables lumps M to be differentiated even if they are in contact on the belt T. In a fourth embodiment, Fig. 18 (not shown), the sensor is similar to that just described except that the coils 47a and b and cores 48a and b are rotatably mounted in the end of a rod 60 and the gaps 49a and b are larger. By moving, e.g. swinging, the rod, such an arrangement may be used to differentiate between fixed objects, the separating means in this case comprising, for example, trap doors for causing lumps 5 to fall to a lower level. The stations may be moved instead of the material.

Title: Improvements in or relating to governing devices
IPC: G05D13/00
Filed: 1939-07-21
Abstract: 532,390. Fluid-pressure servomotors. SCHNEIDER & CIE. July 21, 1939, No. 21224. Convention date, Nov. 17, 1938. [Class 135] A servomotor device for controlling the speed of engines is constructed so that the effect of a given speed variation upon the valve member which it controls can be varied in a progressive and continuous manner during the running of the engine by varying the leverage between the servomotor and the valve member. The control valve 13, Fig. 1, is actuated by lever- and-link mechanism 8, 10, 11, 12 and a spring 14 from the piston 9 of a servomotor device comprising a distributing valve 15 which controls the flow of pressure fluid between the cylinder 2 and an inlet pipe 3 and outlet pipe 4. The valve 15 is controlled by a piston 16 supplied by pipes 7, 6 with fluid from a centrifugal pump driven by the engine, and an extension spring 17 connects the piston 16 to the valve 15. In a modification the pressure fluid may act directly on the bottom of the valve 15 which serves as a plunger, and the movement of the valve is resisted by a compression spring. The lever 11 is also connected by links 23 to a lever 19 and links 21, 22, to a rod 18 integral with the plunger 16, so that the position of valve 13 depends also on the position of the plunger 16, and the effect of the rod 18 on the lever 19 can be varied by adjusting the pivot pins 27 to which the links 21 are connected. These pins 27, Fig. 2, are adjustable by screw-and-nut mechanism 28, 29, 30 operable by a handle 31 during running. Other methods of varying the connection between the rod 18 and the links 23 may be employed. In Fig. 4 the rod 18 is pivoted to the ends of a link 34 formed of two parts connected by screws and nuts 35, 36, and the adjustment is effected by a screw 41 which adjusts a universal joint 39, 40 about which the link 34 can pivot, so that the distances m, l Fig. 4 which determine the.turning movements about the shaft 39 can be varied. Other methods of varying the adjustment of the lever mechanism during running can be employed.

Abstract: 1,198,565. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 May, 1968 [18 May, 1967], No. 21275/68. Heading G6C. [Also in Division B3] In forming a sealed enclosure, e.g. a nuclear fuel element by welding at least one end-cap to a tube, the peripheral surface of the end-cap is formed with a large number of small grooves which when the end cap is inserted in the tube maintains communication between the exterior and interior of the tube, the assembly is positioned in a chamber containing an atmosphere, e.g. a vacuum or inert gas, different from the free atmosphere and the end cap is welded to the tube in such manner as to close the ducts. Grooves may also be formed in the surface of the tube adjacent the end-cap. An annular tapered end-cap 14 is forced between the concentric walls 8, 10 of a fuel element, the walls being of a magnesiumzirconium alloy. Inclined or axial grooves 26 are provided on the inner and outer surfaces of the end-cap, e.g. by milling. Welding is effected by an electron or laser beam in a vacuum chamber. The welding proceeds in a direction such that the inner ends of inclined grooves are sealed first. If an inert gas is to be contained in the fuel element, the welding chamber contains an inert gas, e.g. argon, and gas shielded arc-welding is effected with or without a consumable electrode. After welding, the walls are pressed into grooves 12. Annular or solid end-caps of circular, rectangular and star-shape may be used to seal correspondingly shaped tubes. A refractory insulator 20, of say magnesium oxide, having a grooved periphery may be located adjacent the end-cap.

Abstract: 657,541. Knitting. HEMPHILL CO. Aug. 7, 1947, No. 21632. Convention date, May 1, 1941. [Class 74 (ii)] In knitting a plain fabric, elastic yarn is inlaid in the initial course of inelastic yarn to form a selvage therewith and is thereafter inlaid at spaced wales in consecutive courses, and an inelastic yarn is drawn into independent stitches at alternate wales in consecutive courses, but is held and linked at intermediate wales, whereby alternate strands of elastic yarn will be inlaid to be held in alternate wales while intermediate strands thereof will be threaded between tuck loops of intermediate wales and plain loops of alternate wales. Alternate needles producing wales 2, 4, 6, &c. are loaded up with elastic yarn 1 for four courses, the yarn being fed under suitable, preferably relatively light tension and cleared. All needles then take and draw loops of an inelastic yarn 11 in course A. In the succeeding courses B to D, elastic yarn is similarly fed to alternate needles and cleared below their latches. In course B, all needles take the inelastic yarn, alternate needles knit and intermediate needles producing wales 3, 5, 7, &c. tuck. In course C, the inelastic yarn 11 is taken and knitted as in course A, all latches being cleared and held loops being cast-off. Course D is a duplicate of course B. These courses C and D may be repeated as desired, to provide a tuck edge and one or more plain knit inelastic courses may be inserted between the initial selvage course and the tuck courses. Tuck courses may be separated by plain knit courses, any of which may have inlaid elastic yarn. The body of the fabric, represented by courses E to G, may be of any desired construction, with or without elastic yarn which, if included, may be inlaid or knitted in at desired wales and courses ; shown are plain knitted courses, having elastic yarn inlaid on alternate needles at each course. Held loops may be accumulated over more than two courses. The method is used to produce a mock-rib top and selvage of a stocking. Only needles which take the elastic yarn in their hooks and which knit at every course, are provided with jacks 18. Such needles are raised, by jack cam 30, to clear and to take inelastic yarn 11 ; and, by jack cam 31, to take elastic yarn 1 at a height less than clearing height, from a feeder 35, which may be moved into and out of action, a cam 32 then drawing them down. The other needles also take yarn 11, but clear only when a cam 25 is moved inwardly. Specification 548,951 is referred to.
