Title: Process for the photochemical production of screen diapositives for the production of photomechanical printing surfaces
IPC: G03F5/00
Filed: 1930-05-26
Abstract: 351,201. Photo-mechanical printing- surfaces. BEKK & KAULEN CHEMISCHE FABRIK GES., DR., 102, Hindenburgdamm, Lichterfelde, Berlin. May 26, 1930, No. 16175. Convention date, May 27, 1929. [Class 98 (ii).] Screen diapositives for the production of printing surfaces, having screen points which can be reduced and re-enlarged as required, are produced by printing from a screen negative on to a silver halide plate which has been bathed in a bichromate solution. A sufficiently long exposure to produce a differentially hardened bichromate image is given, without producing an over-exposed and useless silver image. The silver image is then developed with a strong developer (e.g. glycine) and fixed. The reduction of the screen points may now be effected in any known manner. If re-enlargement of the dots is required the bichromate image is developed in hot water to wash out the unexposed soluble gelatin, and the silver image reintensified with strong intensifiers such as a lead intensifier. Re-enlargement up to the size of the hardened points of the developed bichromate image is possible. Re-intensification of the silver image, without actual re-enlargement of the image dots, may be effected with mercury or copper intensifiers without a hot-water development of the bichromate image. The reduction and re-intensification with or without re-enlargement may be effected locally.

Title: Improvements in or relating to the separation of wax from hydrocarbon mixtures
IPC: C10G73/06
Filed: 1948-06-18
Abstract: A process for the separation of a desired wax in solid form, from a hydrocarbon mixture containing the desired wax and also undesired waxy and/or oily constituents, comprises diluting the hydrocarbon mixture, when at such a temperature that the whole of the desired wax is in solid form, with a solvent for components of the mixture other than the desired wax, increasing the temperature of the dilute mixture by an amount such that form 2 to 30 per cent of the desired wax is dissolved in the solvent, thereafter again reducing the temperature of the mixture to the solidification temperature of the desired wax and separating the desired solidified wax from the solution.  The process is applicable to the solvent dewaxing of mineral oils, particularly lubricating oil stocks, to the deoiling of wax, e.g. slack wax from dewaxing operations and to the separation of various grades of wax by solvent fractionation or fractional crystallization of petroleum mixtures comprising wax.  If desired, the solvent employed may comprise a mixture of an oil solvent and a wax anti-solvent.  Oil solvents mentioned are aromatic hydrocarbons such as benzol or toluol, low boiling aliphatic ethers such as isopropyl ether, halogenated aliphatic hydrocarbons such as propylene dichloride, and chlorinated aromatic hydrocarbons such as chlorobenzene.  Wax anti-solvents mentioned are aliphatic ketones such as acetone or methyl ethyl ketone, sulphur dioxide, furfural, phenol, benzaldehyde, formates and acetates.  The solvent may be added to the hydrocarbon mixture either in a single addition or by successive additions.  Apparatus is described whereby the process of the invention is applied to the dewaxing of mineral oil to produce an oil fraction suitable for use as a lubricating oil and separation of the wax into various waxes having different physical properties.  In the examples, wax cakes obtained by the solvent dewaxing of mineral oil are deoiled according to the process of the invention using a mixture of methyl ethyl ketone and toluene or a mixture of methyl ethyl ketone, tuloene and benzene as the solvent.  Specification 534,462 is referred to.

Abstract: 1,034,805. Knitting machines. B. T. R. REYMES-COLE. July 9, 1962 [July 8, 1961; July 22, 1961; March 12, 1962], Nos. 16436/61, 9413/62 and 16434/62. Divided out of 1, 034, 803. Heading D1C. In a circular knitting machine, the setting of a needle cam 73, a trick wheel or other means for effecting needle movements is varied by a slide bar 63 coupled to a follower device 29, 30 engaging a cam 28 rotating at the same rate as the relative rotation between the cam box and needle cylinder, the extent of the stroke of the follower device during which the slide bar is operated being variable. A bar 32 pivoted to a lever 38 pivoted with lever 30 at 31 has a slot 35 at its other end riding on a spindle 36 and a follower 39 engaging a cam 40 on spindle 36 which is racked round one step for each rotation of the cam box or the cylinder. Pivoted to bar 32 is a lever 33 with a notch 53 and a cam face 54 which can co-operate with a cam face 55 on a block 57 secured to lever 30 so that lever 33 and hence bar 32 is oscillated to rock a lever 58 engaging its left hand end Fig. 1. Lever 58 engages an adjustable stop 62 on slide bar 63, Fig. 4 (not shown), when the lower end of the latter rides off a cam segment 27 on the control drum. A projection 64 on the upper end of bar 63 co-operates with an arm 65 secured to a pivoted spindle 66 carrying lever arms 68, 69. A pigtail 70 on lever 69 engages a pin 71 on cam 73, Fig. 6 (not shown), which with cam 74 forms a clearing cam, cam 73 operating on needles with short butts to raise them from tucking height to clearing height. Block 56 rides into notch 53 driving a part of the rotation of cam 28 which is varied by the position of cam 40 and moves progressively to the right or left, Fig. 1, to increase or decrease the arc over which tucking occurs. A course in which tuck loops are found must be followed by a course of plain stitches so cam 73 must be raised independently of lever 33 and this is achieved by a toe portion 82, on a pivoted lever 79 which is rocked by cam 86, engaging lever 68. A trick wheel, Fig. 7 (not shown), for selecting needles to produce micromesh fabric may be operated by similar mechanism. The arrangements may also be used to select needles to produce longer or shorter than normal loops e.g. in a stocking heel.

A blank round of ammunition comprises a propellant powder charge arranged within a sleeve-like body, and a tamping consisting of a loose mixture of carcass or rubber meal or a similar elastomeric material and a pulverulent material with lubricating properties, e.g. graphite or molybdenum sulphide placed on a cover closing the charge space, the sleeve-like body being sealed off at the top by a disc secured to the body. The pulverulent material may be present in a proportion of 5% by weight. In one embodiment, Fig. 1, the tamping is contained within a metal shell case 1 having a threaded percussion primer 2 and a propellant charge 3 enclosed within a polystyrene cylinder 4, and is confined within two layers 7 and 9 by cardboard discs 6, 8 and 10 cemented to the wall of the shell case. In order to obtain a loud report on firing the shell, two covers 11 and 12 are cemented into the shell case and sealed with lacquer or synthetic resin to form a compression chamber 13. In another embodiment, Fig. 2, the sleeve-like body 21 is made of foamed polystyrene which disintegrates on firing and the propellant charge 3 is contained within a bag 22 cemented to the inside wall of the body 21. A cross-spaced polystyrene spacer 24 is located above the propellant charge and a primer charge 23 is located on its underside. Discs 10 and 26 seal the mouth of the body 21. In a modification, Fig. 3 (not shown), the cardboard discs (6), (8) and (10) separating the tamping layers extend through the walls of the cylinder (21). When graphite is used as the pulverulent material it forms a fine coating in the gun barrel on firing and protects it from the hot gases.
