Title: Improvements in or relating to crushing or pressing rollers
IPC: B02C4/30
Filed: 1955-11-22
Abstract: 805,305. Roller mills. BONSER, A. Nov. 19, 1956 [Nov. 22, 1955], No. 33432/55. Class 59 [Also in Group IX] A pair of burr - crushing rollers are rotatably mounted about parallel axes, one roller 11 being movable towards and away from the other roller 10, and pressure is applied to the shaft extensions 13 of roller 11, at position between the ends of the roller and the ends of the shaft extension, in a radial direction at an angle of not more than 90 degrees to the plane containing the roller axes but at opposite sides of the plane at opposite ends of the roller. As shown, the roller axes are in a vertical plane and pressure is applied by hydraulic cylinders 23, 24 through rods 21, 22 to pressure bearings 19, 20. Rods 21, 22 are adjustably inclined to the vertical so as to apply to roller 11 a vertical loading, and also a horizontal couple which tends to slightly twist the roller so that pressure transmitted between the rollers is progressively relieved towards the ends of the rollers; this pressure relief is arranged to balance the pressure increase towards the roller ends due to roller bending. The rollers may be loaded vertically by sepa ate means applied to bearings carrying the upper roller shaft; rods 21, 22 may then be inclined as shown, or alternatively horizontal.

Title: Improvements in or relating to hand-embroidering machines
IPC: D05C11/10
Filed: 1922-12-07
Abstract: 190,166. Klaiber, C., and Rohner, E., (Assignees of Eberhardt, H.). Dec. 9, 1921, [Convention date]. Embroidery machines.-In Heilmann embroidery-machines, the thread take-up is decreased after each stitch by mechanism actuated by the movement of the material as it yields when the thread is tautened. Festoon forks 14, and shears 15, mounted on bell-crank levers 16, or other parts engaging the cloth, are normally held vertical by a spring and, when shifted by movement of the material, transmit a slight rotation to axiallymovable spindles 27, 28 through levers 20 and ratchet-and-pawl connections 24, 25. The inner ends of the spindles 27, 28 engage in a fixed sleeve 29 and the members are oppositely threaded so that movement of the material produces uniform intermittent motion of stops 32, 33 towards each other. The stops 32, 33, and also a nut 41 mounted on a screwed spindle 35, loosely engage a rod 34. Chain-wheels 9, 10, alternately, are coupled to a continuously-driven shaft by means of clutches 12, 13 and through the free-wheel gears 39, 38 and 36, respectively and rotate the spindle 35 in opposite directions. The, wheels 9, 10 also drive, through bevel gears 8, the thread take-up mechanism. Arms 42, 45 of levers pivoted at 44 engage respectively in grooved collars 31, fixed to the spindles 27, 28 and in the members 12, 13. The clutches 12, 13 are held open alternately by means of a pivoted angle-part 62, projections 64 on which engage behind pins 65 depending from the lever-arms 45. The part 62 has an arm 61 rocked by a crank 58 on a shaft 57, which is oscillated intermittently from a switch-cam 48 on a continuously-running shaft 47. When the nut 41 strikes the stop 32 it moves the spindle 28 axially, so de-clutching the wheels 9. The wheel 10 is then coupled to the shaft 11 and the spindle 35 oppositely rotated until the nut 41 strikes the stop 32. The take-up mechanisms on opposite sides of the material are thus driven alternately, the takeup decreasing with the travel of the nut 41.

Abstract: 846,567. Semi-conductors. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 2, 1956 [Nov. 5, 1955], No. 33520/56. Class 37. The resistivity or conductivity type of a semiconductor body is modified by heating the body in contact with a mixture 'of an active material and a neutral material, the latter remaining solid during the process. The Figure shows semi-conductor bodies 3 immersed in the powder mixture 4 in a quartz tube 1, through which nitrogen or nitrogen and hydrogen are passed. In one example a P-type germanium disc was heated in contact with a mixture of 5 % H  3 PO  4  and 95 % SiO 2 , the phosphorus producing a thin N-type layer. In another example an outer N-type layer was produced on a P-type silicon disc by using a mixture of quartz powder and phosphoric acid. Other suitable mixtures are quartz powder and boron, antimony or arsenic trioxide. Alternatively, quartz, gallium trioxide and antimony trioxide may be used which produces an inner P-type layer and an outer N- type layer on a base of N-type silicon. Magnesium oxide, aluminium oxide, stannic oxide, and zirconium oxide may be used in place of quartz. The active material may be a liquid or gas or vaporised metal absorbed in the solid neutral material.

Abstract: 1,150,270. Pulse frequency detectors. MARCONI Ltd. 2 Aug., 1966 [10 Aug., 1965], No. 34649/66. Headings H3A and H3T. A circuit for detecting the frequency difference between two pulse trains of frequencies f 1  and f 2  produces an output on line B<SP>1</SP> when f 1  is greater than f 2 , and on line C<SP>1</SP> when f 2  is greater than f 1 . Assume f 1  is greater than f 2  and that bi-stable circuit A, A<SP>1</SP> is in the state where transistor A<SP>1</SP> is conducting and transistor A cut off. If a pulse in train f 2  overlaps a pulse in train f 1 , transistor NAND gate B is rendered conducting to produce an output pulse on line B<SP>1</SP>, and feed an inhibit pulse, lengthened by circuit D, to the input, thus preventing the bistable circuit being switched by a pulse in train f 2 . During the time the pulses do not overlap no output and inhibit pulses are produced and the bi-stable circuit is switched by each f 1  and f 2  pulse. With f 1  less than f 2 , and overlapping pulses, the bi-stable circuit is maintained in the state in which A is conducting and A<SP>1</SP> cut off by an inhibit pulse derived from NAND gate C. The outputs on lines B<SP>1</SP>, C<SP>1</SP> are in the form of pulses whose widths are modulated in accordance with the amount of overlap of the pulses in the two pulse trains f 1 , f 2 . Varying D.C. signal may be derived from these output signals, e.g. by integration and used for A.F.C.
