Title: Improvements in the production of ketoximes
Filed: 1956-08-08
Abstract: A process for the production of ketoximes consists in acting on a saturated aliphatic or cycloaliphatic hydrocarbon while it is being irradiated with light of from about 300 to 600 millicrons wavelength with dry hydrogen chloride, chlorine and nitrogen monoxide, the molar ratio of Cl2 : NO being from 1 : 8 to 2 : 1, and neutralizthe oxime hydrochloride obtained.  The hydrocarbon may be saturated with hydrogen chloride initially when only a little, if any, need be added with the nitric oxide and chlorine or the whole of the hydrogen chloride may be added with the nitric oxide and chlorine.  The oximes are obtained from the hydrochlorides by dissolving the latter in water and neutralizing the solutions with caustic alkali or ammonia solutions.  In examples light is provided by a mercury immersion lamp and cyclohexanone oxime (1); cyclo-octanone oxime (2); and a mixture of heptanone oximes (3) are obtained, respectively using cyclohexane, cyclo-octane and n-heptane as starting materials.

An image reproducing device comprises a cathode-ray tube with a display screen formed by a sheet of electroluminescent material 15, Fig. 3, and a photoconductive plate 16 sandwiched between electrodes 14, 19, the photoconductive plate having apertures 18 lined with photoconductive material 20 so that the electrical resistance of the material 20 is varied when the electron beam of the tube penetrates the apertures, means for causing the beam to scan the screen, a source of potential connected to the electrodes 14, 19 whereby the electroluminescent sheet 15 is excited to luminesce over an elementary area in the neighbourhood of an aperture 18 entered by the beam, the arrangement being such that positive optical feedback occurs between the electroluminescent material and the photoconductive material so that the brightness of the area tends to increase towards an equilibrium value, and means are provided for preventing the brightness of the area reaching the equilibrium value. It is stated that by suitable feed-back halftone reproduction is obtainable. Feedback may be obtained by making the plate 16 opaque so that the feedback path of the light between the electroluminescent and photoconductive layers is restricted. The exciting source may be deenergized at intervals corresponding to the picture frame by means of a blanking pulse generated in a circuit operated by the frame scanning circuit or, to avoid vertical shading effects, the exciting source may be cut off after each picture line by forming the electrode 19 into linear sections parallel to the scanning lines and providing a control means operated by the line scanning circuit which disconnect the exciting source from each linear section in turn after the electron beam has scanned the corresponding line. Specification 765,579 is referred to.

Title: Improvements in or relating to metal casting presses
IPC: B22D17/20
Filed: 1958-07-30
Abstract: 869,288. Hydraulic presses. TOS, RAKOVNIK, NARODNI PODNIK. July 30, 1958 [Sept. 6, 1957], No. 24548/58. Class 69 (2). [Also in Group XXII] The bottom piston 14 of a vertical coldpressure press, for casting metals, is raised hydraulically by a telescopic ram. Molten metal is poured into the cold chamber 15 when the lower piston 14 is positioned, as in Fig. I, to obturate the aperture leading to the mould. The upper piston 13 is then operated to force the piston 14 downwardly until the seat 8 engages a seating face 10, Fig. I, thus uncovering the aperture to permit metal to flow into the mould. After solidification, piston 13 is withdrawn, and, to eject the metal remaining within the chamber 15, pressure liquid is admitted to cylinder 1 to raise telescopic pistons 2, 3 together until piston 2 is stopped by engagement of the seats 5, 7. Thereafter piston 3 continues its upward movement within piston 2 until stopped by engagement of seats 8, 9, Fig. III (not shown). The piston 3 is subject on its upper face to a constant pressure from port 17 which, upon release of pressure in cylinder 1, lowers piston 3 to the Fig. I position ready for a further charge of molten metal. Piston 2 is held in this position by friction, or alternatively, by maintaining a minimum pressure in line 18 by a valve 20.
