Title: Improvements in and relating to the glazing of photographic prints
IPC: G03D15/02
Filed: 1947-12-12
Abstract: 634,957. Glazing photographic prints. KODAK, Ltd., and SOPER, A. K. Dec. 12, 1947, No. 32865. [Class 98 (ii)] A photographic print is glazed by pressing the wet image-carrying side into intimate contact with a smooth surface which has been treated with an organic derivative of silicon to increase the water-repellency, allowing the print to dry, and detaching it from the surface. The organic derivative of silicon may be an alkyl, aryl, aralkyl, or alkaryl silicon halide (e.g. ethyl, propyl, butyl, phenyl, phenylmethyl, or tolyl silicon halide), an incompletely substituted compound such as (CH 3 ) 2 HSiCl and its homologues, an organo-silicon amine, a halogen-polysiloxane wherein some or all of the halogen radicals are substituted by amino or borate groups, or a mixture thereof. The silicon compound may be used in the vapour form or as liquid, either alone or in an inert solvent. After vapour treatment the surface may be aired or treated with ammonia, and after liquid treatment the surface may be treated with caustic alkali. The surface may be glass, a metal plate or sheet coated with a vitreous or ceramic enamel, wood, paper, a synthetic resin sheet, a cellulose derivative such as a cellulose ester (e.g. the acetate or propionate and the partially hydrolysed esters), regenerated cellulose, or celluloid. The emulsion binder may be gelatin (preferably not fully hardened), albumen, zein, a polyvinyl compound, or regenerated cellulose. In an example, glass is treated with the vapour of a mixture of chlormethyl silanes sold under the Registered Trade Mark " Teddol " and is aired, a wet processed print is pressed thereon, allowed to dry, and then stripped off. Specifications 572,740, 575,675, 575,696, 593,727, [all in Group VIII], and 599,153, [Group XXIII], are referred to.

Title: Improvements in or relating to the stabilisation of chlorinated paraffin wax
IPC: C10G73/38
Filed: 1945-12-05
Abstract: Chlorinated paraffin wax is stabilized by incorporating at least 0.5 per cent of triethanolamine.  Chlorinated waxes of differing chlorine content or their mixtures with such substances as esters, employed as plasticizers, may be treated, the amount of stabilizer being in excess of that required to neutralize all the hydrogen chloride liable to be liberated.  Chlorinated paraffin wax with dibutyl phthalate in proportions of 60 : 40 by weight is stabilized by addition of 1 per cent of triethanolamine for 3-4 hrs. at 160 DEG  C. or for at least 4-5 months at ordinary temperature.  The colour imparted by the stabilizer may be removed by known methods for removing resinified impurities, e.g. filtration through fuller's earth.  Triethanolamine inhibits the catalytic effect of metals and their compounds such as iron, zinc and iron halides.  Examples compare the hydrogen chloride evolved when a chlorinated wax of 41 per cent chlorine content contaminated with small amounts of iron, tin, zinc and aluminium is heated at 160 DEG  C., alone or after addition of 1 per cent triethanolamine and/or small amounts of ferric chloride.  The effect of varying amounts of stabilizer, 0.1, 0.6 and 1 per cent, on a chlorinated wax, dibutyl phthalate mixture, with or without added iron, is also shown.  Specifications 418,230 and 495,410 are referred to.

Title: A process for the preparation of cyclohexanone-oxime from the oxidation products of cyclohexane
Filed: 1962-08-29
Abstract: Cyclohexanone-oxime is produced from a reaction mixture formed by oxidizing cyclohexane, the reaction mixture containing cyclohexanone, by reacting this cyclohexanone with hydroxylamine in aqueous solution preferably in counter current to form cyclohexanone oxime, and extracting the cyclohexanone oxime from the mixture with an alkali-re-acting aqueous solution, and precipitating the cyclohexanone-oxime from the extractant by an acid-reacting aqueous solution e.g. hydroxylamine or hydroxylamine chlorhydrate.  The extraction is preferably carried out at low temperature and in a counter current direction.  Before precipitating the oxime it is preferably treated with cyclohexane in counter current direction and the cyclohexone which is being used for the extraction of the aqueous extraction solution containing the cyclohexanone oxime is preferably re-cycled with the reaction mixture.  The mixture containing the cyclohexone may be passed over an ion-exchange resin after the extraction of the cyclohexanone oxime, and then subjected to further oxidation to form more cyclohexanone. Examples are described with the aid of flow diagrams.

Filed: 1975-08-11
Abstract: 1501732 Automatic control of plasma arc torch CATERPILLAR TRACTOR CO 11 Aug 1975 [4 Dec 1974] 33367/75 Heading G3R The spacing between a plasma arc torch and a workpiece is regulated in accordance with sensed voltage and current across the gap. One of the voltage and current signals is inverted and then summed with the other signal and with a third signal to form a control signal which is used to drive the torch automatically towards an optimum position. As shown in Fig. 1, a plasma arc cutting torch 11 is initially driven to a desired position above a workpiece 12 by a motor 14 under manual 17 or automatic control 18, 19. During cutting operation, the motor 14 is controlled by a circuit which receives input signals derived from a voltmeter 20 and ammeter 21 connected across and in series with the working gap respectively. These signals are passed by differential amplifiers G2, G5 to summing amplifiers G3, G6 for combination with reference signals K 1, K2 to form signals of opposite polarity which are summed together with a reference voltage K3 in a summing amplifier G7. The magnitudes of the reference voltages are chosen so that the output of the amplifier G7 is zero when the torch 11 is in its desired position. Subsequent changes in gap spacing produce an error signal which is amplified G8 and filtered F1 before feeding to the drive circuit 16 for the motor 14. A circuit 25 connected to the filter circuit F1 switches off the power to the torch if the output from amplifier G7 is excessive. A relay switching circuit for the apparatus is described, Fig. 2 (not shown), and some circuit details are given, Fig. 3 (not shown).

Title: Improvements in sound reproducers
IPC: H04R11/08
Filed: 1928-11-14
Abstract: 325,478. Western Electric Co., Ltd., (Bell Telephone Laboratories, In,c.). Nov. 14, 1928. Gramophone pick-ups. - A sound-reproducer comprises a movable armature 4 co-operating with a magnetic circuit and engaging a record surface through the medium of a long, light and rigid stylus 5 which is attached directly to the armature and adapted to oscillate about an axis in or closely adjacent to the armature. The ratio of the stiffness of the stylus to the effective mass of the moving system at the stylus point is so great that the natural period of oscillation of the assembly is near or above the upper limit of frequencies to be reproduced. The stylus 5 is fitted with a threaded base 11, Fig. 3, for engaging a threaded stud 7 projecting from the armature 4 as shown in Fig. 1, and the armature together with a pair of arms 8 extending at rightangles to the armature, is sweated or brazed to a diaphragm 2 constituting a flexible closure to a casing 1 which encloses a bi-polar reproducer and viscuous damping material 3. In one form the stylus 5 is a conical nickel shell having a length of 1 inch and effective mass of 0.0034 grams, and the effective mass of the armature and diaphragm is 0.0066 grams. The point of the stylus may be shaped to conform to the record groove and then plated with a hard metal such as chromium. If desired, the stylus may be formed by electro-deposition. The damping material 3 in the container 1 is arranged to offer a mechanical resistance to motion substantially equal to 2 multiplied by the resonant frequency of the movable-system multiplied by the effective mass of the moving system at the stylus point. The net restoring force acting on the system, which represents the difference between the stiffness of the diaphragm and the elastic force due to the magnetic, effect of the polarizing field, is reduced to a limit very little above that necessary normally to maintain the armature in a free central position. The reproducer is stated to be particularly applicable for the reproduction from soft wax records such as the original wax record upon which the sound is recorded. Various formulae and graphs of such formulae are given in the Specification to illustrate how the invention is to be applied.
