Title: Improvements in or relating to gasfilled electric rectifying tubes
IPC: H01J17/04
Filed: 1930-03-10
Abstract: 345,080. Discharge rectifiers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. March 10, 1930, No. 7792. Convention date, March 27, 1929. Addition to 293,327, [Class 39 (i), Electric lamps, Arc &c.]. [Class 39 (i).] The gas-filled electric rectifying tube described in the parent Specification is modified by surrounding the cathode along its whole length, or along the greater part thereof, with an electrically conducting member whose section perpendicular to the longitudinal axis of the incandescent cathode is closed, or is apertured only at a portion which is turned away from the anode. In one form, Figs. 1 and 2, the metal member 6 surrounding the cathode 5 has a longitudinal aperture at its lower portion, and its section in a plane through the axis of the tube and that of the cathode is shaped as a trapezium, the longer parallel side of which is directed towards the anodes 7, 8. A metal screen 9 between the anodes may be formed integrally with the member 6 by bending a metal plate to the requisite shape, the screen 9 being electrically connected to one cathode support 3 and insulated from the other 4. The anodes 7, 8 are preferably of carbon, and to prevent disintegration, their leading-in wires may be surrounded by sleeves 10, 11 of insulating material. The tube may be filled with argon, mercury vapour, or other gas.

Title: Improvements in meat slicing-machines
IPC: B26D7/32
Filed: 1927-03-21
Abstract: 281,149. Warchalowski, A. March 21, 1927. Cutting slices in succession.- In a slicing-machine having a disc-knife driven by an electric motor, the motor is mounted on the casing of the knife with its shaft vertical. As shown in Figs. 2 and 3, the casing 2 carries a motor 3 having a worm 5 on its vertical shaft 4, meshing with a worm wheel 6 attached to the back of the knife 7. The front of the knife is guarded by a removable casing 8. A fence-plate 10 is adjusted, for slice-thickness adjustment, along guides 11 by a screw 12 and hand-wheel 13. A support 14 having depending pins 15 is arranged in front of the plate 10 and extends throughout the length of the machine. The pins 15 pass through guides 16 and rest on arms 17 on a shaft 18, a torsion spring 19 tending to maintain the support in its uppermost position. The weight of the article being sliced depresses the support 14, and the levers 17 then rest on a stop which closes the electric circuit. By this arrangement the motor rotates as long as the substance is pushed to and fro along the support 14, and stops when the substance is removed. As shown in Fig. 2, the contracted lower part 20 of the casing permits the slicereceiving surface, which may be the platform of a weighing-device, to be placed close to the cutter. A plate 22 prevents the pinching of pieces of meat between the receiving, surface and the casing.

Title: Haptoglobin in aqueous solution and process for tits preparation
IPC: C07K14/47
Filed: 1974-02-21
Abstract: To prepare purified human serum haptoglobin, aqueous solutions of alpha - and  beta -globulin fractions from human blood plasma are subjected to ammonium sulphate fractionation. The precipitates which separate out at ammonium sulphate concentrations of 30 to 40 % are collected and dissolved in water and contacted with an anion exchanger, whereupon the haptoglobin is chemically bound thereto. To obtain the pure haptoglobin, it is eluted from the ion exchanger. The haptoglobin is suitable for preventing or treating haemolytic kidney disorders.

Abstract: 413,816. Chocolate. DAUS, H., 26, Bluff Street, Upper Hawthorn, Victoria, Australia. March 20, 1933, No. 8399. [Class 129.] Chocolate is manufactured by grinding and mixing the cocoa nibs, sugar and cocoa butter in a single apparatus. The grinding and mixing apparatus comprises a rotary drum 1 driven by an electric motor 12 by means of a worm gear. The weight of the drum and its contents is carried by two wheels 15 mounted on brackets 16. The cocoa nibs, &c., are introduced into the drum through an opening closed by the cover 20 and are thoroughly mixed and pulverized by heavy rollers 22, 23, 26. The rollers 22, 23 are of the same diameter and grind against the floor 24 of the drum. They are prevented from upward movement by end rings 25. The roller 26 is surmounted on the rollers 22, 23. A small roller 30 is provided to prevent dislodgment of the roller 26. Bulged portions 35 are provided on the floor of the drum to increase the homogenizing action of the apparatus. The drum may be suitably heated by means such as gas jets, steam or hot water coils. The chocolate is discharged through the opening formed by removing the cover plate 54. This opening is large enough to permit removal of the rollers for replacement or cleaning. Scraper plates 61 may be provided on the shaft 62 to remove adhering chocolate from the interior of the drum. Ozonized air may be introduced through the shaft 62 towards the end of the process.

Abstract: 628,024. inductances. KOLSTER BRANDES. Ltd., and GIFFORD, J. March 28, 1947, No. 8463. [Class 38 (ii)] An air-cored inductance comprises an open helix 1 of stiff metal wire having its two ends 3, 4 firmly attached to a rigid base-plate 2 of insulating material so that they are insulated from one another, the materials being such that when a change occurs in the ambient temperature the change of inductance of the helix due to the change in diameter of the coil dependent upon the coefficient of expansion of the metal forming the coil, combined with the change of inductance due to the change in axial length of the helix, dependent upon the coefficient of expansion of the material forming the baseplate, result in a desired change in the inductance of the helix. By a suitable choice of materials for the helix and base-plate any desired change of inductance with temperature may be obtained. For fine adjustment of the inductance a small magnetic dust core 8 on a threaded rod 7 is provided. The base-plate may, in special cases, be constructed of a combination of insulating materials and metals or alloys, provided that the ends of the helix are insulated from each other.

[Class 38 (ii)] In a converter or rectifier in which the A.C. circuit 10 and D.C. circuit 11 are inter-connected by a transformer 12 and high vacuum valves 13, 14, 15, the impedance of the latter is controlled by grid potentials of a wave form corresponding to that part of the A.C. voltages which lies above the intersecting points E, Fig. 2. Thus the D.C. voltage is maintained free from ripple in the case of rectifier operation, or the A.C. voltage is maintained sinusoidal in the case of inverter operation, whilst a constant relationship is maintained between the D.C. voltage and the R.M.S. value of the A.C. voltage. The grid voltages are derived from resistances 35, 36, 37 in the anode circuits of auxiliary high vacuum valves 27, 28, 29 the grids of which are energized from an auxiliary secondary 25 on the main transformer 12.
