Title: An improved method of metallisation by cathode disintegration
IPC: H01J37/34
Filed: 1937-06-17
Abstract: 486,629. Deposition of metals by electric discharge. BERGHAUS, B. June 17, 1937, No. 16919. Convention date, June 17, 1936. Drawings to Specification. [Class 41] In metallization by cathode disintegration, the cathode is first heated by an electric current without application of the disintegrating voltage ; an intermittent disintegrating voltage is then applied and the heating current is applied periodically so as to alternate with disintegration. The duration of the heating impulses may be different from that of the rest periods. The cross-section of the cathode is greater than that which would produce a maximum amount of disintegration without auxiliary heating. Specifications 390,319 and 470,614 are referred to.

Patent GB-1019361-A (GB)
Title: Dispersion coating compositions
Inventor: COUSENS RICHARD HENRY
IPC: C09D125/14
Filed: 1961-05-10
Abstract: A coating composition comprises a dispersion of film-forming polymer particles stabilized in a non-solvent organic liquid by a material comprising one constituent which is compatible with the polymer and incorporated in the disperse polymer particles and another which is solvated by the organic liquid, the organic liquid consisting essentially of high-boiling liquid in a proportion, relative to the solid content of the composition, of at least 1: 1.6 by volume, and sufficient low-boiling liquid to render the composition sprayable. Preferably the high-boiling liquid boils above 150 DEG  C. and the low-boiling liquid boils in a range of 60 to 120 DEG  C.  The dispersions are made by polymerizing monomeric material in an organic solvent which is a non-solvent for the resulting polymer and which contains a preformed polymer as a precursor for the stabilizer which is formed by graft or block polymerization with the monomeric material.  Monomers specified are styrene and its derivatives, acrylic and methacrylic acids and their esters and amides, acrylonitrile, vinyl and allyl esters, vinyl and vinylidene chlorides, dimethyl itaconate and maleate and maleic anhydride. The examples describe: (1) copolymerizing methyl methacrylate and methacrylic acid in solution in a mixture of high- and low-boiling aliphatic hydrocarbons containing degraded rubber dissolved therein, and adding a mixture of methyl cyclohexanyl phthalate, titanium dioxide, rosin-modified alkyd resin and aliphatic hydrocarbon to the resulting copolymer dispersion; and (2) copolymerizing styrene, ethyl acrylate and acrylonitrile in solution in methanol containing an acrylate of polyethylene glycol dissolved therein, and adding a mixture of titanium dioxide and ethylene glycol to the resulting copolymer solution.

Title: Fibrous sheet material and method for producing same
IPC: D21H27/00
Filed: 1974-04-18
Abstract: 1443131 Fibrous sheet material SCOTT PAPER CO 18 April 1974 [30 April 1973] 17112/74 Headings D1R, D2A and D2B A fibrous sheet material 71 suitable for use in the manufacture of soft, absorbent, sanitary towels and wipers comprises a web having surface regions 74 located on each side of a central core region 76, which has less fibre concentration than the surface regions, a first bonding material 75 extending through at least one of the surface regions and a second bonding material 73 extending from one surface region through the central core region to the opposite surface region in a fine, spaced-apart pattern occupying less area in the plane of the web than the first bonding material. The fibres may be wood pulp, cotton, rayon, cellulose ester e.g. cellulose acetate, polyamide, acrylic, polyester, vinyl, protein, fluorocarbon, or nitrite fibres. The fibres may be treated with' a conventional cationic debonding agent prior to or after web formation. The bonding material may be an acrylate latex rubber emulsion; acrylate, vinyl acetate, vinyl chloride, or methacrylate resin emulsion; a water-soluble resin e.g. carboxymethyl cellulose, polyvinyl alcohol, or polyacrylamide; or mixtures of any of the above with a low molecular weight starch e.g. dextrin; or an elastomeric material e.g. butadiene-styrene, neoprene, a vinyl polymer or copolymer, nylon, or vinyl-ethylene terepolymer. The web may be made by a papermaking process on a foraminous woven wire. Preferably, the web is formed under conditions of reduced pressing while it is wet in order to obtain the relatively low degree of interfibre bonding strength. After drying, the web may be creped. The first and second bonding materials may be applied to the web by means of appropriate rotogravure rolls. The web may be further creped after application of both bonding materials, or after application of each bonding material, or only after application of the first bonding material, (Figs 2-4, not shown). The web may also be made by deposition of dry fibres upon a forming surface.

Patent GB-863520-A (GB)
Title: Apparatus for bringing two moving indicia marks into register with each other
IPC: B65H23/188
Filed: 1959-05-21
Abstract: 863,520. Automatic registration control systems. HELMES, G. P., HELMES, W. P. M., HELMES, C. T., HELMES, J. P., and HELMES, F. J., [trading as HELMES MACHINEFABRIEK]. May 21, 1959 [May 22, 1958], No. 17251/59. Class 38 (4). In a system for automatically synchronizing two moving bodies each carrying a series of marks, one series of marks influences a lightsensitive device to produce one set of pulses and the other series of marks produces another set of pulses which are oscillated in time relative to their synchronous time so that when there is coincidence between pulses in the two sets, indicating error, correction is initiated in the appropriate sense. In a rotary printing machine, Fig. 1, a paper web receives impressions in different colours from printing cylinders 2-5 which are followed by drying rollers 6. Before the web reaches each cylinder, marks printed on the web by a preceding cylinder cause a light sensitive element 8 to produce a series of pulses in synchronism with movement of the web. Rotation of the cylinder moves a screen 11 past another light-sensitive element 10 to produce a second series of pulses. A cam 17, driven through 1/12 reduction gearing from the cylinder, oscillates light-sensitive element 10 six times with decreasing amplitudes about a position corresponding to that at which the two sets of pulses would coincide if registration were correct. In consequence, coincidence only occurs when registration is in error to an extent corresponding to the amplitude of one of the oscillations. A magnet 42, Fig. 3, is then energized by a thyratron coincidence circuit (not shown) to attract levers 44, 45 and thereby release levers 29, 30 so that they follow cams 24, 25 driven with cam 17 and cut away over alternate 30 degree sectors to correspond with the sense of displacement of light-sensitive element 10 relative to its mean position. The appropriate lever 29 or 30 thus operates a corresponding switch 33 or 34 to run a motor 46 in the direction necessary to restore synchronism by adjusting the relative position of the cylinder through a differential gear (not shown). The switch 33 or 34 is reset at the end of the rotation of cam 17 by one of the projections 26 on a cam 22 or 23 and, since the correction of large errors is initiated earlier during the rotation of cam 17 than in the case of smaller errors, the duration of each correction is thus dependent on the magnitude of error. An alternative method of correction in which the paper web is controlled by means of an adjustable tension roller is referred to.

Abstract: 1376522 Making magnetic transducing heads INTERNATIONAL COMPUTERS Ltd 13 April 1973 [15 April 1972] 17477/72 Heading B3A A method of making a magnetic transducing head includes providing a member 4; providing a plurality of apertured magnetic laminations (3), Fig. 2 (not shown), with the apertures (10) aligned along a common axis; assembling the laminations on to the member 4; bonding the laminations to one another and to the member to form a stack; forming two flat, parallel surfaces 12 on the stack; forming an assembly by bonding two magnetic C-shaped members 5 each terminating in a pair of co-planar surfaces, one to each of the surfaces 12 with the coplanar surfaces spaced from the respective surface 12 to which it is bonded; and removing material from the bonded assembly to form a face parallel to the common axis to produce a surface having magnetic gaps between the C- shaped members and the stack and partially exposing the core member 4 on the face. The core member comprises a body 8 of magnetic material having a high permeability, e.g. a nickel alloy, with a thin layer 9 of non-magnetic material, e.g. copper, on either side. The apertured laminations (3) are a sliding fit over the core member and they may be made by precision etching. The C-shaped members 5 are assembled from laminations (6), Fig. 1 (not shown), which together with the laminations (3), are made from the same material as the body 8. The members 5 are spaced from the surfaces 12 by gaps 7 formed by spacers of non-magnetic material. The operating surface of the head is formed by machining along a line 14 and if necessary also along a line 16, to remove a lower portion 17. A multi-track head may be made by forming the centre core portion from a number of stacks alternately threaded on a common core member with inter-track spacers, the C-shaped core members being also formed from stacks interleaved with spacers.

Abstract: 130,349. Vessey, E. A. Nov. 30. 1917. Screw propellers.-The blade spigots are fitted to have a limited radial movement in their sockets so as to vary the effective propeller diameter, while the blades may have the pitch varied by the same movement. The centrifugal force acting on the blades is resisted by balanced tension elements 23. Fig. 4 shows a part section, and Fig. 1 a plan, of the front of an aeroplane. The shell or hub H carries integral or separable tubular sockets 2, each of which receives a doublyconed blade spigot 9, which is held in position by a slit wedge sleeve 16 filling the conical space between the spigot and the cylindrical .shell 8, and by a two-part screwed ring 18. The shell 8 has an externally threaded boss 7, which engages the internally threaded socket 3 carried by the socket 2. A rod 23 connects the boss 7 and the axially movable spring-pressed sleeve 27 fitted with studs 31, which are screwed into a sliding flange 32 having ball thrusts, as shown. The non-rotating ring 33 is controlled from the pilot's seat by a lever h and screwed rod m. Other means for varying the pitch may be employed, e.g. a transverse pin may engage in spiral slots in the walls of the socket 2. The sockets H, 2 are inclined a little to the plane at right-angles to the propeller shaft. The position of the ring 33 may be varied.

Abstract: 652,184. Aerials. BELLING & LEE, Ltd. July 2, 1948, No. 17881. Addition to 621,876. [Class 40 (vii)] An aerial system comprises a half-wave V- aerial structurally combined with and electrically connected in parallel with a further half-wave aerial, the resonant frequency of which is either one-half or twice that of the V-aerial. The aerial, which is a modification of the aerial described in the parent Speci. fication, includes a half-wave V-aerial comprised of the elements 13, 14 (Figs. 1 and 2), secured in an insulator 4 by means of screws 15, 16 through which electrical contact is made between the elements 13, 14 and a balanced transmission line 19 via conducting strips 7 and 8. A second insulator 5 arranged co-axially with insulator 4 and supported thereon by means of a screw 6 carries two elements 26, 27 between which and the elements 13, 14 electrical contact is made by means of screws 28, 29 the heads of which are in sliding contact with two arcuate conducting portions 9, 10 (Fig. 3), arranged on the top surface of insulator 4 and in electrical contact with screws 15 and 16 respectively. The elements 26, 27 may be of one-half or of twice the length of the elements 13, 14, and may have an upright V-shape instead of the shape shown. The complete system is supported by means of a tubular mast 20, the top end of which is split so that it can be tightened on to the insulator 4 by means of a clamping ring 21. When operating at the higher of the two frequencies at which the system resonates the effect of the elements associated with the lower frequency resonance is said to be equivalent to a resistance of about 4000 ohms shunted across the transmission whose characteristic impedance is 80 ohms. When operating at the lower resonant frequency the elements associated with the higher frequency resonance act as a capacitative reactance of about 300 shunted across the transmission line.
