Title: Interpolymers of n-vinylacetamides
IPC: C08F226/02
Filed: 1964-08-04
Abstract: Copolymers of an N-hydrocarbon substituted N-vinyl acetamide and a polymerizable ethylenically unsaturated compound in which the hydrocarbon substituent is an aliphatic hydrocarbon radical having at least 2 carbon atoms or an aromatic hydrocarbon radical, are obtained by polymerizing in the presence of a non-oxidizing free-radical initiator at a temperature of 0-100 DEG  C.  The polymerization may be carried out in bulk or in an organic solvent solution or in a buffered aqueous solution. The examples relate to copolymers with vinyl acetate (which may be hydrolysed), maleic anhydride, acrylic acid.

Title: Logical devices utilizing selective plating techniques
IPC: H03K19/16
Filed: 1961-08-25
Abstract: 927,018. Circuits employing bi-stable magnetic elements. NATIONAL CASH REGISTER CO. Aug. 25, 1961 [Nov. 1, 1960], No. 30656/61. Class 40 (9). [Also in Group XXXVI] A number of substrates such as phosphorbronze tubes 10, 11, 12, 13 carry discrete coatings 14-21 of thin magnetic film, each coating having a direction of easy magnetization. The coatings are so spaced that each of conductors 22-25 links all the tubes and embraces a column of magnetic coatings. The direction of easy magnetization in a coating is oblique to the axis of the tube on which it is mounted and is also oblique to the column conductors 22-25 so that the direction of magnetization may be reversed by a current in either an associated tube or an associated column conductor. The output is available on the column conductor or the tube. In Fig. 1, a signal on a single one of terminals X1, X2, X3, X4 is converted into a binary output on terminals A, B, C, D. A signal on X1 is converted to D.C.B.A. (0111) which represents the decimal digit 7. A signal on a single terminal of A, B, C or D is converted into a binary output on X1, X2, X3, and X4. A second set of coatings 34-39 may be carried on the tubes 10-13 and the windings 22-25 may be adjusted manually from one set of coatings 14-21 to the other 22-25. Additional conductors may be threaded through the tubes if required. Full binary to decimal conversion, Fig. 3.- Four binary digits on terminals 142-149 are converted to a decimal output on a single one of terminals 1-9. A clock winding 199 tends to produce output pulses on all the terminals 1-9. Four binary digits on terminals 142-149 generate pulses in all but one of the tubes 76-84 in opposition to the clock pulse so that an output remains on only one terminal. Logical element, Fig. 4.-Half-write inputs on terminals A-D and half-write inputs on terminals R-U produce an output pulse on terminal 164 representing the function The output winding 163 links all the tubes 159-162 and all their magnetic coatings. The Specification describes an electrolytic process for depositing the magnetic coatings on the tubes in accordance with Specification 896,263 [Group XXXVI]. To determine the easy direction of magnetization, the tubes are formed with helical grooves before the coating is deposited.

Title: Improvements relating to bearings
IPC: F16N19/00
Filed: 1924-12-20
Abstract: 226,565. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Bethel, C.). Dec. 20, 1923, [Convention date]. Capillary action lubricating; liquid level, maintaining. - A bearing structure wherein an hermetically closed oil chamber communicates at its lower part with an oil chamber from which oil is supplied to the bearing proper by capillary feeding means has means affording free communication between the atmosphere and a level in the oil reservoir above that at which the latter communicates with the oil chamber. Means are also provided to enable the reservoir to be refilled without breaking the hermetical closure thereof. The bearing casing has oil chambers 6, 9, 10 intercommunicating by passages 8, 11. The chamber 9 is filled with material for supplying oil by capillary attraction through an opening 4 to the bearing. The chamber 6 is air tight except for a filling passage 16, Fig. 1, the upper end of which opens to the atmospehere and the lower end 20 of which opens into the chamber 6 at the level 15 at which it is desired to maintain the oil in the chamber 9. A U-tube 22 having its short arm 26 open near the top of the chamber 6 acts as an air vent when filling the chamber through the passage 16, also the liquid in the tube 22 forms an air-tight seal as the oil level 21 drops. The bend 27 of the tube 22 is below the level 15. A dust cap 28 and lid 29 cover the open ends of the tube 22 and passage 16. In operation the chamber 9 is: supplied with oil so that the level 15 is constant from the chamber 6, air bubbling under the end 20 of the passage 16 into the upper part of the chamber 6. An oil tank 31 and a hose connection 32 may be used for refilling the oil chamber 6. In a modification the passage 16 is replaced by a tube 36, Fig. 3 and the vent pipe 45 has. above the level 15, an .arm 53 fitted with a cock 54. To prevent constant dripping of oil from the arm 53 the cock 54 is shut off after the chamber 6 has been refilled. To quicken the filling operation a pump 55 may be used. In a further modification the tube 36, Fig. 3, is combined with the tube 22, Fig. 1, the long arm 25 of the latter passing up the inside of the tube 36 and opening to the atmosphere below the top thereof. Specifications 222,456 and 224,519 are referred to.

Abstract: 832,427. Printing surfaces. MYERS, R. R. Oct. 1, 1957, No. 30728/57. Class 100(2) A method of producing printing plates includes the steps of taking a metallic printing shell 10, applying a first adhesive layer 14 to the back of the shell, placing a sheet of plastic material 16 on the adhesive-coated shell, placing a sheet 18 of perforated light metal on the free side of the plastic material 16 with a second adhesive layer 20 therebetween and heating the assembled plate and compressing it in a press.. A thin layer of backing metal 12 is preferably first applied to the shell 10 to fill any irregularities therein. When the assembled and heated plate is compressed the plastic material, e.g. a thermoplastic material such as vinyl acetate-vinyl chloride, compensates for irregularities in the adjacent areas of the shell 10 and sheet 18 by passing into the perforations of the sheet 18 without weakening the remainder of the plastic sheet. Adhesion between the sheets 16 and 18 is also increased by the plastic material which passes into the perforations. The metal sheet 18 is preferably made of aluminium alloy.

Alternatively the record may contain a row of images each in the form of an elongated rectangle, Fig.7 (not shown). A beam 4 of coherent light passes through a condenser 5 and diffuser 6 and is then passed through the record 2<SP>1</SP> and directed through an aperture in a diaphragm 9 to a photographic plate 8. At the same time a reference beam 4<SP>1</SP> from the same source is incident on the plate 8. By moving the plate and the record 2<SP>1</SP> simultaneously a hologram is produced on the plate which comprises a plurality of elements each corresponding to one of the images on the record. A Fresnel lens (13), Fig.8 (not shown) may be used to direct the light passed through the record through the aperture. The hologram is developed and an image produced from it by illuminating it with coherent light. The view of the image from a given point will then correspond to a view of the object seen from a corresponding point. If a colour film and coherent light of different wavelengths are used a coloured image is obtained.
