Title: Improvements in photographic diffusion transfer processes
IPC: G03C8/06
Filed: 1959-03-26
Abstract: 912,258. Photographic silver salt diffusion transfer processes. KODAK Ltd. March 26, 1959 [March 31, 1958], No. 10503/59. Class 98 (2). The transfer is effected in the presence of a silver halide solvent and an onium compound consisting of either a quaternary ammonium salt or a ternary sulphonium salt, the onium radical thereof having an attached chain of at least seven atoms. Such compound may initially be used in the emulsion, the developer, or the transfer material. Improvements therewith include increase in density of the positive image, increase in emulsion speed, rate of development and solvent action of the silver halide solvent as well as image production in neutral black. Two main classes of the sulphonium salts and four of the ammonium salts are quoted with numerous individual compounds falling therein, and an extensive list of tone-modifying substances such as heterocyclic nitrogen and sulphur containing compounds of the type used in rubber chemistry, for use together with such salts, is provided. Numerous amines effective in darkening the tone of the transferred images, especially when used in conjunction with such tone-modifying substances, are listed also ; and a further modification for the same purpose is the use of solvents such as the lower alcohols, ketones, amides and ethers to the extent of 7 to 20% by volume in the developing solutions. Gold salts and other sensitizing materials, and antifoggants such as azaindene compounds may be used in the negative layers from which transfer is made. Twenty-two examples, many of which describe the procedure with several of the onium compounds and quote the relative densities of the transferred images, are provided; thus in Example 1 high-speed bromoiodide emulsions sensitized with methyl-3: 3<SP>1</SP>- diethyl seleno carbocyanine iodide and with gold and sulphur compounds and containing also 4- hydroxy - 6 - methyl - 1: 3: 3a: 7 - tetrazaindene as well as various specified amounts of 7 : 18 - diaza - 6: 19 - dioxotetracosane - 1: 24- bis (pyridinium perchlorate) and 3 : 6 : 9 : 12: 15 : 18 : 21: 24 - octoxahexacosane : 1: 26 - bis (pyridinium bromide) as the quaternary ammonium salts are exposed on an intensity-scale sensitometer, treated with a specified transfer developer and rolled in contact with receiving sheets coated with a gelatine solution containing a dispersion prepared from aqueous lead acetate, zinc nitrate and silver nitrate precipitated with aqueous sodium sulphide and sodium metasilicate with a proportion of nitric acid to obtain positive images on such sheets.

Abstract: 554,114. Inductances. STANDARD TELEPHONES & CABLES, Ltd. July 31, 1942, No. 10733. Convention date, Aug. 28, 1941. [Class 38 (ii)] [Also in Group XXXVII] In a relay or other device having a middle winding 4 sandwiched between two windings 3, 5 connected in series, the number of turns of the winding 4 equals the sum of the turns of the windings 3, 5 and the number of turns of the winding 3 differs from that of the winding 5. The relative sizes of the windings 3 and 5 is calculated or determined by experiment so as to give the highest degree of inductive balance between the winding 4 and the winding 3, 5. This is important in telephone systems where the two windings are connected to the tip and ring conductors of the talking circuit and quiet speech transmission is essential. The theoretical considerations determining the proportion of turns of winding 3 to winding 5 are discussed and in one example the ratio was 2/3.
Patent GB-743523-A (GB)
Title: Improvements in or relating to the detonation process of making carbon black
IPC: C09C1/48
Filed: 1952-04-29
Abstract: <PICT:0743523/III/1> <PICT:0743523/III/2> Carbon black is produced by introducing a detonation charge into one end of an elongated reaction zone and make hydrocarbon charge into the remaining portion of the zone, said make hydrocarbon charge having an oxygen to carbon ratio of less than one and being capable of sustaining a detonation wave, interposing a rupturable diaphragm or a narrow zone of inert gas between the make charge and the detonation charge, igniting the detonation charge thereby causing a detonation wave to pass in the reaction zone through the make hydrocarbon thereby producing carbon black which is recovered.  In Fig. 1 the reactor is made up of two pipes 10 and 12 preferably of the same diameter flanged and bolted at 14 and having a "Cellophane" (R.T.M.) barrier inserted across their cross-section at this point.  Cover plates 22 and 24, the latter being provided with a spark plug 26 close the ends of the cylinder so formed and detonation charge is passed into the portion 12 through pipe 28 and make gas to the portion 10 through pipe 30. The passage of the detonation wave initiated by the spark from 26 is recorded on an oscilloscope 20 by the pressure exerted on piezo-electric gauges 18.  Following detonation, combustion gases can be drawn off through pipe 28 or 30 and carbon black recovered from the retort by removing the cover plate 22.  Fig. 2 illustrates a continuous process wherein the retort 40 is fed through pipes 52, 54 and 56 respectively with a detonation charge, an inert gas barrier, and make gas.  The feeding of these components is automatically controlled by controller 78 which also operates valve 46 at the end of the reactor to allow the products of the detonation to pass to a carbon black separator 50. The gases may be fed to the retort at pressures as low as 330 millimetres of mercury as well as pressures greater than atmospheric. The make gas may be made up of acetylene alone or mixed with oxygen or other hydrocarbon, or ethylene/oxygen and butane/oxygen mixtures may be used as well as compound mixtures of methane, acetylene and oxygen.  Vaporized or finely dispersed liquid hydrocarbons mixed with oxygen or air are also suitable raw materials.  Whilst any suitable detonating mixture may be used, stoichiometric mixtures of oxygen and hydrogen, oxygen and acetylene or oxygen and carbon monoxide are preferred.

Title: Improvements relating to wheel-suspension arrangements for vehicles
IPC: B60K17/16
Filed: 1955-04-15
Abstract: 768,420. Mounting gearboxes. DAIMLERBENZ. AKT.-GES. April 15, 1955 [April 15, 1954], No. 10978/55. Class 79(3). [Also in Group XXXII] Relates to a wheel suspension arrangement comprising pendulous half axles which are connected by hinge joints to an axle carrier mounted resiliently on the superstructure or frame of the vehicle and are abutted against the superstructure in the direction of travel by thrust links, preferably articulated to the half axles below the axle centres. According to the invention, the axle carrier is constructed as a substantially vertical supporting member the upper end of which is mounted, above the axle centres, with resilience in all directions and which is abutted relatively softly against lateral swinging about that end, whilst its lower, laterally yieldable part carries the half axles preferably on a common joint axis, below the axle centres, one of the half axles preferably having an axle gear connected to it. As shown, half axles 12, 13 are abutted against a frame 9 by thrust links 14, 15 of U-section, which are pivoted to the frame by rubber cushions and are connected with the half axles through rubber sleeves 18. The links are sprung by coil springs 19. The half axles are pivoted on a common axis 20 to an axle carrier 21, in the form of a pin, which is supported at its upper end by a rubber cushion 22 and towards its lower end by a rubber ring 29, the arrangement being such that the pin is free to rock about the upper joint constituted by the cushion 22. The latter is provided with holes or cavities 28. The rubber members 22 and 29 are pre-stressed by a securing nut 26. The carrier 21 also provides a bearing 33 for a pivot pin 34 for the half axles 12, 13. An adjustable thrust member 40 is connected between a projection 38 of the bearing 33 and the frame 9, the connection to the projection 38 being made through a rubber joint 39<SP>1</SP> and that to the frame being made through a pair of pre-compressed rubber cushions 42, 43. The carrier 21 and or the joint 22 may alternatively be provided behind the half axles instead of in front of them as shown. The carrier may be arranged to swing freely in the longitudinal direction while being resiliently supported in the transverse direction, in which case the thrust member 40 may be dispensed with. The connection of the half axles to the carrier may be resilient in all directions and the carrier may be supported in one vertical direction only by the cushion 22 and in the opposite direction by the ring 29.

Title: Improvements in and relating to separating fluid components by molecular sieves
Inventor: STEWART JAMES LYON
IPC: C10G25/03
Filed: 1960-03-29
Abstract: Components of a mixture of fluids are separated by selective absorption in the vapour phase using a molecular sieve in a series of adsorption and desorption steps, which comprises terminating the adsorption step while the bed remains substantially unsaturated, preferably not more than half saturated, with respect to the saturation characteristic hereinafter desscribed, the bed remaining in this unsaturated state until desorbed.  The desorption step may be effected by increasing the temperature, and/or decreasing the pressure and/or passing an inert gas which is substantially unadsorbed, e.g. nitrogen, through the molecular sieve, or by any combination of the above methods.  Portions of the sieve may be operated out of phase to treat a continuous stream.  Static bed or fluidized bed as well as batchwise procedure may be employed and operated at sub, super or atmospheric pressure and any temperature. Suitable methods for determining the adsorption capacity are described and have to be determined at the operating conditions to be employed.  The invention is described in respect of the treatment of light naphtha in a static bed of zeolitic molecular sieve to achieve separation of n-paraffins from the feedstock and the examples contain a comparison of operation with saturation of the bed, which results in the early destruction of the adsorbent.

Title: Sewing and trimming machine
IPC: D05B37/04
Filed: 1936-04-18
Abstract: 455,001. Sewing-machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.- (Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) April 18, 1936, No. 11151. [Class 112] A trimming and sewing machine for producing smoothly trimmed and sharply curved edges in work incorporates work-feeding and plytrimming devices such that the speed of the feeding device and the frequency of the trimming element are relatively variable without stopping the machine. The invention is shown as applied to a lock-stitching machine with the under-thread and feed-dog mechanisms housed in a pillar 2, a presser roller 16 of usual type oo-operating with the dog feed. A boss 18 on the machine arm 4 has attached a flat bracket 19 carrying a knife-bar 21 in suitable bearings for reciprocation in a path inclined to the vertical. The knife-bar has a holder 22 for a straight edge trimmer knife 23. This knife severs the work parallel to the line of stitching at the side of the needle 11 opposite to the presser roller 16. A collar 25 is secured on the knife bar 21 and is connected by a link 26 to an arm 27 of a bracket on a bar 28 which can only reciprocate vertically in the head 5. The bar 28 has a notch 30 to receive a coupling pin 31 carried by a crank-arm 32 of the shaft 33. The other end of the shaft 33 engages a pivoted hand lever 37 by which means the trimming knife is put out of action by disengaging the pin and slot 31, 30. Re-engagement is effected by a lever 43 which has a lateral extension 45 engaging the upper end of the knife-bar 21 and depressing it against the spring 42, this depressing also the bar 28 to re-engage the pin and slot 31, 30. Extending rearwardly from the rock-shaft 33 and rigidly secured thereto is a rock-arm 46 with a forked free end embracing the eccentric 47 carried by the rotor shaft 48 of the electric motor 49. This motor is separate from the electric motor driving the sewing machine so that the speed of the feed and trimmer knife may be varied independently. The driving motor 59 for the sewing machine, Fig. 5, comprises the usual friction clutch 61 and foot control mechanism 64, 66, 67. In sewing along straight lines, the motors 49, 59 operate at the same speed, but in turning corners, the speed of the motor 59 is diminished, while that of the motor 49 remains the same, so that the knife makes a greater number of reciprocations than the number of feed strokes, so ensuring a neatly trimmed curved result.
