Title: Photographic copying apparatus
IPC: B41L19/00
Filed: 1964-06-18
Abstract: 1,074,596. Photographic copying apparatus. EASTMAN KODAK CO. June 18, 1964 [June 18, 1963], No. 25209/65. Heading G2A. In a copying apparatus of the type in which an image transfer is effected between a matrix and a copy sheet pressed together between heated rollers, the rollers are housed in an insulated enclosure which is maintained within a desired temperature range. Fig. 2 shows the arrangement with the two rollers 12 and 18 in contact at the right hand side, but in an "exploded" view at the left hand side. Roller 12 is fixed in position, but roller 18 can be moved towards or away from roller 12, the degree of pressure between them when they are in contact being adjustable by altering the tension of a spring 24. The whole apparatus is built up on a base which forms part of an outer casing. The juxtaposed matrix and copy sheets 30 are fed in through a duct bounded by plates 31, 32, and guided up between rollers 12, 18 to pass out of the machine through guide 33. An L-shaped cover member 38 co-operates with a frame part of the outer casing to form an enclosure for the rollers, this enclosure being blanketed with a layer 43 of insulating material. The enclosure is heated by means of an electrical heating element 42, controlled by a thermostat whose probe 44 is mounted adjacent the lower guide plate 32, so that it is responsive to the cooler sheets as they are fed into the machine, the temperature thus being regulated up to the desired level again before the sheets reach the pressure rollers. Roller 18 is retracted out of engagement with roller 12 when the machine is not in operation, to avoid the formation of "flats" on the rollers. This is effected electromechanically by an arrangement of cams and switches. When the apparatus is switched on, roller 18 is automatically brought into contact with roller 12, and when the apparatus is switched off again, roller 18 is automatically retracted again.

Abstract: 1,113,461. Gear pumps and motors. SHIMADZU SEISAKUSHO Ltd. June 18, 1965 [July 31, 1964 (2)], No.25928/65. Heading F1F. A gear pump (or motor) comprising a casing 23, Fig. 1, having a cylindrical centre portion 24 and end closures 25, 26 within which on a drive shaft 31 and driven shaft 35 meshing gears 21 and 22 respectively are mounted, includes in abutment with the opposite side faces of the gears, thrust plates 44, 45 and around the gear peripheries adjacent the meshing area along the addendum circles thereof, sealing members 52, 53, Fig. 3, formed separate from the casing. The thrust plates 44, 45 are recessed both on their faces adjacent the end closures and on their faces adjacent the gears, the areas of these recesses being dimensioned so that the plates are in axial balance from the hydraulic pressure force to which they are subjected. The end closure 25 is formed with an inlet passage 60, Fig. 4, and outlet passage 61 connected with axially directed flow passages 62, 68 respectively and passage spaces 66, 67, 73, 72 so that hydraulic fluid is introduced into and leaves the gear teeth in an axial direction to ensure complete filling of the teeth at the inlet side of the pump. Leaf-springs 58, 59 urge the sealing members 52, 53 into sealing contact with the gears. The spring 58 associated with the inlet sealing member 52 is relatively weak and the spring 59 associated with the outlet sealing member 53 relatively strong, since pressure in the inlet passage 60 is less than that in the outlet passage 61. In a modification, the springs 58, 59 are omitted. In this case the outer peripheries of the sealing members 52, 53 are arcuate and closely adjacent the inner cylindrical surface of the casing 23. The bearings 40, 41 supporting the driven shaft 35 in this case are unsupported by the end closures 25, 26, which in operation of the pump allows slight swing of the gears and thrust plates on the drive shaft and one or other of the sealing members 52, or 53 to engage the inner periphery of the casing 23.

Title: A process for obtaining isotopes of an element or a compound containing such an isotope
IPC: B01D59/34
Filed: 1959-07-29
Abstract: An isotope of an element or a compound containing such isotope is obtained from a mixture of molecules of isotopes of the element in molecular combined form with another element or a mixture of molecules of isotopes of the same element by subjecting the mixture to the action of a monochromatic radiation of a wavelength equal to that of the resonance peak of a molecule of the mixture, which molecule contains or consists of the desired isotope and recovering the desired isotope or a compound containing it.  By this process irradiation of H2, H2O, HF, HCl, HBr, or Hl causes only the molecules containing D to be dissociated to yield nascent D.  The D may be recovered as D2 or the corresponding D compound depending on the temperature and pressure applied.  Alternatively, an element or compound, which has an affinity for D, may be added to the initial compound.  The process can be repeated.  The process is also applicable to the recovery of isotopes of Li, Be, or B.

Abstract: 809,936. Electrolysis. LIBBEY OWENS FORD GLASS CO. Aug. 27, 1956 [Sept. 7, 1955], No. 26074/56. Class 41. A method of at least partially removing an electrically conductive metal oxide film 12, e.g. tin oxide from a non-conductive surface 10, e.g. of glass, provided with an electrode, comprises contacting the film 12 with an aqueous solution of an electrolyte 14 and establishing a voltage between the film 12 and the electrolyte. In deleting tin oxide 12 from a glass pane 10, the electrolyte, which may be an acid, base or salt, may be presented to a restricted area of the film 12 by masking the film 12 or by applying the electrolyte by a draughtsman's pen 13 which is connected at 15 to a voltage source, the other terminal of which is connected at 16 to a bus-bar 11 fired on to the glass 10. The electrical connections may be such as to make the film 12 the anode or cathode, or A.C. may be employed. In another example, the sheet 10 is immersed edgewise in an electrolytic bath, and the sheet 10 may be immersed at constant velocity to provide a graded removal of the film 12. Electrolytes mentioned are hydrochloric, sulphuric and phosphoric acid, the hydroxides of sodium, potassium and ammonium, and ammonium or sodium chloride and sodium sulphate. Voltages of 0.7 to 24 D.C. are mentioned. The electrolytic action in the case of acid and salt electrolytes is to reduce the tin oxide to tin, which remains on the glass 10 when a salt electrolyte is employed, but is dissolved by an acid electrolyte. A base electrolyte is thought to reduce the tin oxide to a soluble stannite.
