Title: Process of producing coloured images in multilayer photographic elements
IPC: G03C7/30
Filed: 1937-11-19
Abstract: 507,841. Colour photography. KODAK, Ltd. (Eastman Kodak Co.) Nov. 19, 1937, No. 31911. [Class 98 (ii)] A process of producing colour developed reversed images in a photographic element having three silver halide emulsion layers coated on the same side of a single support, one of the outer layers being not specially colour-sensitized and the other layers being sensitized to the red and green regions of the spectrum respectively, comprises developing negative images in all the layers, exposing and colour developing the positive image in one or both of the outer layers and exposing the middle layer by visible light passed through the colour developed outer layer or layers and colour developing it, and removing the positive and negative silver when all the layers have been exposed and colour developed. In a particular example, the red-sensitive layer is next the support and the green- and blue-sensitive layers are coated thereon, red and yellow filters being provided respectively between the red and blue-green, and the green and blue layers if desired. 'After exposure, the film is developed to black and white by a developer containing potassium thiocyanate, and, after washing, is exposed from the support side to light passed through a red filter. The film is then colour developed to give a blue-green positive image in the lower layer. If the yellow filter layer is still present, the middle layer may be exposed by white light passed through the colour developed layer, but if the filter is absent, the green sensitizer must be resistant to development and this layer exposed by green light passed through the lower layer. The middle layer is then colour developed to magenta, after which the blue sensitive layer is exposed and colour developed, the positive and negative silver being then removed from all layers by a potassium ferricyanide bath. This bath should also remove any filter layer present such as colloidal silver. If the filter layer resists development, then the upper layer may be exposed first with blue light, then the lower layer, and the middle layer exposed last. The green and red sensitive layers may be reversed in order, the green layer being nearest the support. Examples of colour developers containing potassium thiocyanate are given. An antihalation layer of nickel sulphide in gelatine may be coated on one or both sides of the support, and is removable by the potassium ferricyanide bath. Other sequences of exposure are described in the Specification, and the colour couplers may be contained in one or more of the sensitive layers. Specifications 440,032, 447, 748, 458,664, 458,665, and 500,826 are referred to.

Title: Improvements in ram cylinders
IPC: E21F13/08
Filed: 1965-07-27
Abstract: 1,078,834. Fluid pressure jacks. KLOCKNER-WERKE A.G. July 27, 1965 [July 28, 1964], No. 31953/65. Heading B8J. [Also in Division F1] A double acting ram unit comprises a pressurizable expanding seal 8 mounted in the body of a piston with an annular face 2a and a full face 2b. A piston rod 3 includes a pressure supply duct 1 communicating with the interior of the seal 8 and a by-pass duct 9 with a non- return valve 10 communicating with the interior of the seal 8 and with the chamber on the side of the annular face 2a. When pressure is applied to the annular face 2a through a pipe (not shown) the valve 10 is closed and isolates the interior of the seal 8 so that pressure can be transmitted through the clearance between the seal 8 and the inside of the cylinder, the pressures in the chambers on both sides of the piston becoming the same with consequent extension of the ram. Admission of pressure through the duct 1 seals the seal 8 against the inside of the cylinder insolating the chamber of the full face 2b from the chamber of the annular face 2a so that the ram is retracted, pressure medium trapped in the full face piston chamber escaping through an exhaust (not shown).

Title: Method for the sealing off of electric lamps
IPC: H01J9/38
Filed: 1936-11-27
Abstract: 485,937. Electric incandescent lamps with residual gases. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) Nov. 27, 1936, No. 32520. Drawings to Specification. [Class 39 (ii)] In a method of filling and sealing the envelope of an electric lamp containing a gas filling comprising a mixture of gases at a pressure substantially exceeding that of one atmosphere a part of the gas filling is introduced into the envelope and condensed by cooling the envelope, this temperature being maintained while another gas, which does not condense at that particular temperature, is introduced in a quantity which is insufficient to raise the pressure within the envelope to above one atmosphere, after which the bulb is sealed off. In an example the bulb of an electric incandescent lamp is connected to a system of tubes whereby it is connected first to an exhausting-pump and then to a container filled with krypton or xenon, or a mixture of those gases, at a predetermined pressure. The tap to the gas supply is then closed, and the lamp bulb cooled by immersion in a container filled with liquid air, which condenses the gas filling and reduces its pressure, whereupon the inlet tube is connected to a supply of nitrogen and finally sealed off in the usual manner by directing flames upon it. The lamp is then removed from the cooling-vessel and allowed to regain its normal temperature. Specification 473,863 is referred to.

Title: Apparatus for automatically applying wire round a package
Inventor: BILT PIETER ARNOLDUS VAN DE
IPC: B65B13/02
Filed: 1964-08-13
Abstract: 1,073,145. Bundling-machines. N. V. METAVERPA. Aug. 13, 1964, No. 32977/64. Heading B8C. [Also in Division F2] Packages are supplied, e.g. to a wire-applying machine, by means of an intermittently-driven belt conveyer 7, the trailing end of each package depressing a movable plate 22 as it leaves a threshold 21 and thereby actuating a solenoid (30), Fig. 2, to disengage a brake 19 which allows a first cam disc 18 to be rotated and so operate the wire-tying mechanism through a switch 20. The cam disc 18 and similar discs 17 and 16 are each driven by a shaft 15 through spring- loaded members (23) (see Division F2) which slip on the shaft 15 so long as the brake 19 is applied. Each disc 16-18 has a pin 26-28 respectively. The pin 28 of the disc 18 holds the disc 17 against rotation, and similarly the pin 27 on the disc 17 holds the disc 16. The brake 19 initially engages the pin 28, until disengaged by the action of the package on the plate 21. On release of the pin 28 all three discs begin to rotate: the brake 19 then returns to hold the pin 27 of disc 17, thereby preventing discs 17 and 16 from further rotation. Disc 18 continues to rotate, and by means of cams a and b actuates the switch 20 to cause the trailing end of a package and the leading end of a subsequent package to be tied by wire from a frame 5. Further actuation of the plate 21 releases in turn each of discs 17 and 16 to cause further ties to be effected on the last and successive packages. The machine operates continuously. Rollers 6 are all retracted as the wire is applied. A third, central tie may be effected on each package by the inclusion of a plate which pivots as the centre of the package passes over it, thereby operating a circuit to a separate set of cam discs. Again, sets of cam discs may be employed to tie packages at varying distances from their ends, the set corresponding to the size of package being selected automatically, e.g. by the weight of the package.
