Title: Improvements in or relating to electron discharge devices
IPC: H01J25/02
Filed: 1941-12-18
Abstract: 554,202. Electron-oscillators. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Dec. 18, 1941, No. 16373. [Class 39 (i)] In discharge devices of the kind in which an electron beam is velocity modulated by passing through a high frequency electric field and in which the variations in velocity are utilized either with or without conversion into density variations, the velocity control, or the output voltage, or both are effected in a field system of the magnetron or Barkhausen-Kurtz type, into which the beam is led obliquely to the axis of the system. As shown in Fig. 1, the electron stream from a gun 2 is deflected by electrostatic or magnetic means 4, so as to enter obliquely to the axis, the high frequency field established by two semicylindrical electrodes 3. Under the action of an axial magnetic field and the alternating potentials applied to the electrodes, the electrons describe helical paths of increasing or decreasing tangential velocities according to the phase at which they enter the field. On emergence, the electron stream is deflected by the means 7, similar to 4, through the drift space 8, where they are formed into groups of varying density, which are utilized to produce an output voltage by passing through a similar system 9, 10, 11, the electron stream being collected by an anode 14. The device may be used for amplifying, generating, modulating or mixing oscillations. For deflecting, the drift space 8 and system 9, 10, 11 are omitted and the density modulated beam, made to impinge on a collecting electrode, the potential of which is adjusted to reflect the slower moving electrons. Phase and frequency changing may be effected by using systems in the modulating and energy abstracting regions having different numbers of anodes ; and mixing by applying the oscillations of different frequencies to any' of the electrodes. For oscillation generating, the output may be fed back to the velocity modulating system, or the latter may be in circuit with a negative resistance. In a modification, Fig. 2 (not shown), the retarding field is of the Barkhausen-Kurz type with the cathode removed, the electron beam in this case following a zig-zag path in the field.

Title: Process of making olefine oxides
IPC: C07D301/26
Filed: 1924-07-09
Abstract: In the production of olefine oxides by treating chlorhydrins with strong alkali, use is made of chlorhydrin solutions of less than 40 per cent concentration and the olefine oxides are removed as soon as formed.  Preferably solutions containing less than 15 per cent chlorhydrin are employed.  According to the example, a 10 per cent solution of ethylene chlorhydrin is heated to boiling with caustic soda in a kettle surmounted by a reflux condenser and the resulting ethylene oxide condensed in a cooled receiver. Propylene chlorhydrin may be similarly treated to give propylene oxide.  Other alkalis such as alkaline earth hydroxides may be employed and the removal of the product may be effected under reduced pressure.

Title: Leather colouring process
Inventor: THOMASON MICHAEL GORDON
IPC: D06P1/00
Filed: 1958-05-22
Abstract: 887,584. Colouring leather. BARROW HEPBURN & GALE Ltd. April 22, 1959 [May 22, 1958], No. 16522/58. Class 93 Leather is decoratively coloured by applying thereto a coloured coat, applying a differently coloured coating composition on to the first coat over a part of the area covered thereby, and then overprinting either one or both of the differently coloured coatings with a pattern or patterns (i.e. pictures, designs, or other markings) in one or more further colours. Where the leather has been provided with a coloured finishing coat, it is preferred to apply a further overall coating of the same colour over the finishing coat, and to plate the leather after the finishing coat but not after the further coat. In an example, leather stock in the buffed skirt stage is tabled with a pigmented water dye, a coating of an aqueous emulsion colouring-composition is applied, the leather is plated to give a smooth gloss finish, a second coating of an aqueous emulsion colouring composition, preferably of the same colour as the first coating, is applied, and the leather is cut into strips of the desired widths and lengths. Each strip is advanced in contact with the periphery of a rotating disc, the edge face of which has a width less than the width of the strip and passes through a reservoir holding an aqueous emulsion colouring composition of different colour to the first two coatings, the strip being so guided that a differently coloured band is applied thereto either centrally or otherwise. After drying in an infra-red drying unit and cooling, the strip and a pigmented "Cellophane" (Registered Trade Mark) foil is guided between an electrically heated roller embossed in accordance with the pattern to be produced and a plain roller, the foil being stripped from the leather strip as it emerges from between the rollers. A number of colouring discs with independent reservoirs may be arranged to apply differently coloured bands to a number of strips at the same time. A series of infra-red lamps may be suspended over a support for the strips, which are turned over as they pass from the colouring discs. More than one band of colour, of the same or different colours, may be applied to a strip. More than one embossed roller, and two or more pigmented foils may be used for the same strip, the rollers being arranged side by side, or in tandem for successively applying different component parts of a pattern along one band, e.g. two embossed rollers in tandem and two differently coloured foils may be used with the same strip.

Abstract: 470,595. Endless - belt conveyers. NYBORG, T. G., and MINING ENGINEERING CO., Ltd. June 17, 1936, No. 16890. [Class 78 (i)] For returning spillage caught by the lower return run of a belt conveyer to the top conveying run, an auxiliary endlessbelt conveyer is provided adjacent the tension drum of the main conveyer. The auxiliary conveyer 8 passes over a driving roller on an extension of the shaft of the tension drum 3, and is deflected by a pulley 10 to rise up a slope parallel to a portion of the return run of the main conveyer 1 which is snubbed by a roller 2 to pass over a plate 4. The rising part of the conveyer 8 bears on a plate 11 which preferably forms the bottom of a deep-sided trough, and on reaching the level of the top run of the conveyer 1 passes round a pulley 12, which may be adjustable, to reach its driving roller by way of a spacing pulley 13. A plough 5 lies over the downward sloping portion of the return run 1 and pushes the spillage thereon through an opening in the conveyer frame 7 on to the conveyer 8. A horizontal plough 51 may be added to supplement the plough 5. A plough 15 transfers the material from the conveyer 8 through another hole in the frame 7 on to the top run of conveyer 1, and any fines passing the plough 15 fall on a shoot 18 transferring them to the bottom run of conveyer 1. A deflector 17 also ploughs on to this run any material getting between the conveyer 8 and the plate 11 and dragged up to fall on the bottom run of conveyer 8. The belt of conveyer 8 is preferably narrower than that of conveyer 1, and its driving roller is approximately of the same diameter as the drum 3 and is connected to its shaft by a non-return ratchet. The upward slope of the conveyer 8 may rise above the level of the top run of conveyer 1, and the spillage be transferred from the higher portion without employing a horizontal stretch immediately preceding the pulley 12. Specification 452,046 is referred to.
