Filed: 1928-12-22
Abstract: 327,151. Plauson, H. Dec. 22, 1928. R÷ntgen-ray tubes.- In tubes producing X- rays of great penetration used, for example, in radiographing metals, cathode rays rotating spirally in the direction of flight are produced at a hot cathode and are accelerated by an electric field between the cathode and an internal anticathode. A multi-branched cathode fed by multiphase current having a number of phases equal to, or a multiple or sub-multiple of, the number of branches is used. Four branches may be fed with 2-phase current, or three branches in star or delta with 3-phase current. Three star-connected filaments 8 may be supplied with 3-phase heating current through contacts 4 - - 7, high-tension current being fed between the star point of the cathode and the anticathode 41. Electromagnets 33 around the tube may produce a magnetic field rotating in the same direction as the rays at the same frequency as that of the cathode supply, or the electromagnet 33 may be supplied with direct, current to concentrate the rays. A reflecting cap 9 around the filaments is slit at 10 to reduce induced currents.

Title: Improvements in and relating to die-casting machine and method
IPC: B22D17/04
Filed: 1930-12-19
Abstract: 359,800. Casting-machines. PACK, C., 220, 23rd Street, Jackson Heights, Long Island, New York, U.S.A. Dec. 19, 1930, No. 38298. [Class 83 (i).] Casting processes; moulds ; castings, extracting.- Molten metal is poured into a recess 240, Fig. 10, in enclosed communication with a mould-cavity 238 and, after partial solidification, the centre portion is forced into the mould by a plunger D. The plunger is preferably arranged to enter the recess 240 from below and the ejector rods 180 from above. The recess may be formed in a separate member C, Fig. 1, clamped between the plate A in which the mould cavities are formed and a fixed plate 60. The plunger D and member C are water cooled and replaceable, the plunger being normally held with its end just above the bottom of the recess 240 by a piston 18 constantly urged up by oil pressure. The recess 240 is then filled with molten metal and the upper mould plate B is moved down by oil admitted above a piston F. The plunger D is then raised, by oil admitted below a piston 4 to force the centre of the metal charge into the mould and is then withdrawn, to a position below normal, by oil pressure admitted above the piston 4. Oil is then exhausted from above the piston F which is raised by a constant oil pressure in the annular space below the piston thus raising the plate B, cores being withdrawn by a plate 144, Fig. 5, lever 150, and fixed link 154 and ejectors 180 operated by fixed stops 172 engaging projections 170 on the ejector plate 142. To ensure that the metal left in the receptacle is lifted when the plate B rises some of the ejector pins 186, Fig. 7, may be short thus allowing metal to enter and solidify in the recesses 188. The oil is controlled by valves, in a chest 67, Fig. 1, operated by cams which are adjustably mounted on a shaft 92 driven at one-fifth speed from a shaft 100 operated by a hand-wheel 102 or a motor, controlled by one-revolution switch. The rise of the plate B is limited by stops 120. If it is necessary to withdraw a core horizontally it is preferably arranged in the plate B or between the plates and is then withdrawn by pin 196, Fig. 5, and fixed plate 190 with an inclined slot 198. If the core is arranged in the plate A it is withdrawn by a plunger at the same time as the plunger D and controlled by the same valves. When necessary the member C may be arranged eccentrically in one of a number of holes formed in the plate 60, the cylinder 4 being laterally adjustable on rails for this purpose. For large castings two plungers D and two members C may be used or two machines may be combined, two adjacent legs 124 being replaced by one common one. When necessary the pillars 62 may be replaced by others of greater length.

Filed: 1972-08-18
Abstract: 1396908 Piling cloth in rope form DEUTSCHE STEINZEUG UND KUNSTSTOFFWARENFABRIK 18 Aug 1972 [20 Aug 1971] 38592/72 Heading D1L A device for the automatic piling of cloth 2 in rope form comprises a winch roller assembly 4, 6 mounted above a container 34 for the cloth and a laying-in frunk 10 pivotally mounted between the container and the roller assembly, the trunk being suspended on gimbals about the centre of rotation 12, the drive shaft 14 for the outer joint (frame 16) of the gimbals being pivoted by piston and cylinder assembly 62 at an angular velocity slower than that at which the drive shaft 20 of the inner joint carrying the funnel 8 of trunk 10 is pivoted by piston and cylinder assembly 22 so that the end 26 of the trunk is guided back and forth across the bottom 54 of the container (zig-zag line 56) to form a compact pile of the cloth. The gear 64 connecting the more slowly moving shaft 14 to the reciprocating piston 62 includes a rack and pinion device (Figs 3 and 4, not shown) which ensures that angular velocity of the trunk across the container changes towards the limits of oscillation in such a way that the rate of deposition of the cloth remains constant, this rate of deposition being not greater than the rate at which the cloth 2 is delivered. Limit switches 58, 60 are provided above the gimbals to reverse the direction of reciprocation of cylinder 62 and thus of the frame 16. Reversal of the direction of rotation of the more rapidly moving shaft 20 carrying the funnel 8 is achieved either by switching ring 52 mounted on the trunk pressing one or other of semicircular templates 30, 32 against limit switches 36 or 38 respectively or by limit switches 40, 42 mounted at the end 26 of trunk 10 and actuated when the appropriate end 48 or 50 of probes 44, 46 contacts the side wall 28 of the container. Where templates 30 and 32 are used these have to be changed to conform to the cross-sectional shape and size of the container used and where end switches 40, 42 are employed trunk 10 is made in two telescopic halves 43, 45 to allow it to be moved out of the container.

In a revetment, metal plates 10, Fig. 1 (not shown), which are about four feet square, have a longitudinally uniform semi-circular groove 11 pressed at each vertical edge and a third semi-circular groove 12 equally spaced from the grooves 11 and parallel to them. The upper half 12a of groove 12 faces one way and the lower half 12b faces the opposite way so that the groove forms a tubular guide for a pile. A first pile 14 is driven and a plate put in the required position with one of its grooves located on that pile serves as a jig for locating the other piles 14 in the other grooves. A second plate is located with one of its side grooves overlapping the adjacent side groove of the first plate. As the side grooves are of semi-circular cross section a revetment of curved form can also be erected.

Title: Jig washer
IPC: B03B5/20
Filed: 1964-09-23
Abstract: 1,071,078. Jig washers. STAMICARBON N.V. Sept. 23, 1964 [Sept. 23, 1963], No. 38818/64. Heading B2H. The water in a jig washer 1, Fig. 1, is subjected to pulsations in such a manner that, in the first phase of each cycle, the bed of material to be separated, e.g. raw coal, is lifted from the perforated support 2 and there further lifted and expanded by an immediately following impulse of the water acting against the bottom of the raised bed. One or more air chambers 4 opened at the bottom extend across the full width of the jig below the support 2. An air conduit 5 communicating via valves 6, 8 respectively with compressed air supply and atmospheric lines 7, 9 extends alongside the washing compartment and has branches leading into the chambers 4. Each chamber is provided with an elastically extensible cap 10 supported in its lowermost position by a perforated plate 13. The material to be separated is fed via a chute 3. In operation, upon opening of the valve 6, compressed air enters the chambers 4 and cause the caps 10 to be upwardly disturbed. In consequence, the liquid is displaced upwardly through the support 2 and silghtly lifts the bed of material. The liquid levels in the chambers are depressed by the compressed air and cause a further surge of water through the support shortly after the bed has been lifted. Upon closing of the valve 6 and opening of the valve 8 the bed falls and stratification takes place, the fall being accelerated due to contraction of the caps. The fractions of high and low specific gravity are discharged respectively via a pocket 11 and an overflow weir 12. The caps 10 may have flat upper surfaces. In a modification, the air chambers have rigid caps secured by reinforced bellows to the side walls of the air chambers. In a further modification, the chambers, instead of having upwardly displaceable caps, have side walls or side wall portions extensible or displaceable in a lateral direction. Instead of elongated air chambers extending across the width of the washing compartment, the chambers may be cylindrical and may be disposed in rows with two or more chambers in each row. The jig may have a number of washing compartments each with one or more air chambers.
