Title: Improvements in or relating to apparatus for foiling backings
IPC: D21H19/10
Filed: 1956-02-21
Abstract: 808,735. Laminating-apparatus. ACHILLES, W. Feb. 21, 1956, No. 5261/56. Class 140. Cellulose acetate or cellulose hydrate foil to be applied to backings of paper or cardboard is fed from a roll 1 to glue applying roller 3, foilspreading roller 8, direction-changing roller 9 and hence to the nip between driven pressureroller 10 and counter-pressure roller 11, where it is laminated to the backing material. Guide rollers 2 ensure that the foil passes in a predominantly vertical direction through a drying chamber through which air is led from opening 21 in the front of the steel housing of the apparatus to suction pipe 23. The backings are fed to the nip between rolls 10, 11 on a permeable conveyer 12 on which they are laid in separate pieces, with the edges overlapped. Suction from pipe 23 may hold these pieces on the conveyer. The rollers 18 and 19 for the conveyer are fluted rollers. Roller 20 with rail 20a attached to it holds down the pieces while they are fed to the laminating nip. The foil spreading rollers 8 are frictionally driven by rollers 9 and 10 and are provided from the centre outwards with oppositely directed threads. Counter-pressure roller 11 may be rubber-covered and hydraulically mounted. Glue-box 4 has a constant circulation of glue through pipes 5 and 5a and applying roller 3 has a doctor blade acting upon it. Rollers 3, 10, 13 and 18 are driven at substantially equal speeds from motor 25.

Title: Improvements in and relating to metal-steatite joints and to electric discharge apparatus incorporating such joints
IPC: H01J35/18
Filed: 1943-04-02
Abstract: 565,950. Electric discharge tubes. MULLARD RADIO VALVE CO., Ltd., and MYERS, L. M. April 2, 1943, No. 5338. [Class 39 (i)] [Also in Groups II, XXII and XXXVI] A metal-ceramic joint particularly for electric discharge apparatus is made by metallising the steatite or other ceramic component with nickel, plating the metallised surface with copper and then soldering the metal component to the plated component. Metallising may be effected by coating with a colloidal suspension of nickel oxide in a vehicle such as acetone, reducing the oxide in hydrogen and sintering at 1350‹ C. Soldering may be effected by the copper-silver eutectic at a temperature of 800‹ C. The metallised and plated end of the ceramic cylinder 1 may be placed in the metal cylinder 3 with a ring of solder 4 and the joint heated in an induction furnace containing carbon dioxide or other inert atmosphere. For electric devices operating under high frequency conditions, the cylinder 3 is of copper, but for other purposes may be of iron or nickel. In the former case, degassing may be effected up to 600‹ or 700‹ C., and in the latter case at a higher temperature. In joining copper or other discs to a ceramic tube, the butt end of the tube may be metallised and plated and soldered to the disc or the disc may be provided with annular flanges 33, 34 to which the metallised and plated ends of the ceramic tubes are soldered. An electron discharge tube of the lighthouse type has three steatite tubes 9, 10, 11, Fig. 2, with metallised and plated ends soldered to four copper discs 5-8, the disc 8 carrying the anode 14, the disc 7 the grid, the disc 6 the indirectly heated cathode 12 and the disc 5 the current lead 13 for the cathode heating current. The tube may be degassed by heating in a vacuum up to 600‹ C. A high frequency resonator of the Klystron type may be similarly made from metallised and plated ceramic tubes 21-25 and copper discs 15-20, the disc 17 carrying the focussing cylinder 28, and the disc 16 the cathode 26. An X-ray tube has the anode 35 and cathode 41 respectively soldered to metallised and plated members 36, 40, while the member 40 is also soldered to a metal ring 39, which is further soldered to a metallised and plated steatite member 38. The members 36, 38 are soldered to a central metal ring 37 which is normally earthed and contains an opening in which a metallised and plated steatite disc is soldered to serve as a window for the passage of the X-ray beam.

Abstract: 699,197. Photographic exposure-timing apparatus. ENTWISLE, J. J. March 13, 1951 No. 6000/51. Classes 98 (i) and 98 (ii). [Also in Group XXXVII] An exposure-timing and light-intensity controlling apparatus comprises a synchronous motor M driving a shaft 12 which carries a fixed clutch-plate 13 and a loose clutch-plate 14 urged towards the fixed plate by a compression spring 15. The motor drives the plate 13 continuously but the plate 14 is normally prevented from rotating by a stop-pin 17 secured to it abutting the armature 18 of a solenoid SL. When the solenoid is energized by the operation of a switch (not shown) which may be operated by the platen of a photographic negative printing machine, the pin 17 is released and the plate 14 rotates. A cam 20 integral with the plate 14 raises a contact-spring 21 into contact with a fixed contact 23 during a portion of the rotation of the shaft, leaving a period in which the solenoid may be de-energized to enable the armature 18 to arrest the plate 14 at the end of the revolution if desired. For example the speed of the shaft may be two revolutions per second and the cam may close the contacts for 3/16 of a revolution so that in one revolution the lamp connected to the contacts 21, 23 may be lit for # of a second, leaving 1# seconds for the release of the platen. The intensity of the light is controlled by a variable resistance (not shown) provided with an adjusting knob cooperating with a graduated scale indicating various light intensities. Additional calibrations acting as datum marks for use with papers of different speeds may be provided, the resistance being brought fully in and the knob being loosened on the shaft and set to the required datum mark. The knob is then tightened and set to the required intensity mark.
