Title: Method of plating holes
IPC: C25D5/16
Filed: 1973-03-15
Abstract: 1422466 Electro-plating fine holes INTERNATIONAL BUSINESS MACHINES CORP 15 March 1973 [9 June 1972] 12475/73 Heading C7B A method of electro-plating the surface of a hole extending through a substrate comprises providing a hole extending through the substrate which hole has a tapering cross-sectional area, and electroplating the hole, e.g. with copper whilst flowing electrolyte therethrough in the direction of decreasing cross-sectional area. Alternatively the hole may taper from both surfaces of the substrate towards the centre thereof; the direction of electrolyte through the hole being periodically reversed. Electro-deposition may be continued to substantially fill the hole with deposited metal. The initial hole may be formed using a laser or electron beam, and optionally forming an etchant through the hole so formed. A non-conductive substrate may be rendered conductive by electroless plating, or by thermal decomposition of an organo-metallic complex. The apparatus shown allows electroplating of holes 2 in substrate 17 positioned as cathode between anodes 16 of Cu or Pt mesh, electrolyte being pumped through inlet/outlet ports 14, 15 either continuously or in alternate directions according to the shape of the holes to be plated. After plating electrolyte may be removed from the hole with compressed air and rinsing with water, alcohol or acetone. The substrate coated may be of alumina or sapphire.

Title: Method and apparatus for rolling strip
IPC: B21B1/22
Filed: 1966-03-22
Abstract: 1,136,012. Rolling. UNITED STATES STEEL CORP. 22 March, 1966 [7 April, 1965], No. 12619/66. Heading B3M. [Also in Division G3] A strip 5 is rolled between rolls 4, 6, 8 and 10 in an S-shaped path, the roll 8 being driven with a greater torque than roll 6 to produce a tensional force in the strip, a desired ratio being automatically maintained between the tensional force and the compressional force exerted on the strip by the rolls. Motors 40 and 36 drive the rolls 8 and 6, the torques in the driving shafts 42 and 38 being measured by strain gauges 60 and 44 and corresponding signals then fed to amplifiers 70 and 58 and to a differential amplifier 72. Any variation in the torques from a desired ratio, as set by a potentiometer 76A, causes relays 80 and 82 to operate switches controlling the screwdown motors of the mill. Thus if the tension in the strip is measured as being too great in relation to the compression exerted on the strip, the screwdown motors are caused to force the roll 10 downwardly to increase the compression. In a known manner thickness gauges 84 and 86 measure the initial and final strip thicknesses, the gauge 86 providing a signal for adjusting .the speed of motor 40 to maintain the strip thickness constant. Lubricant is fed to the strip from nozzles 90 while a detergent emulsifier or solvent is applied to the strip as it enters the bite between rolls 6 and 8, the frictional force exerted by the roll 8 thereby being greater than that of roll 6.

Abstract: 1,180,472. Metal images. PHILIPS GLOEILAMPENFABRIEKEN N.V. March 20, 1967 [March 19, 1966], No. 12867/67. Heading G2C. Metal images on and/or in substrates are produced by forming a silver sulphite image by imagewise exposing the substrate photo-sensitized either with a diazo sulphonate solution containing a silver salt or with a diazo sulphonate solution containing no silver salt and then treating the exposed material with a 0À02 to 2 motor silver salt solution reducing the silver sulphite image to a silver image and intensifying the latter directly or after activation with Cu, Ni, Co and/or Ag. The reduction of the silver sulphite image to silver may take place simultaneously with the intensification. The activation of the nuclear silver image may be effected with a Pt or Pd salt or, when intensifying with Cu, with HC1 which may contain PdCl 2  or PtCl 2 . The intensification may be effected by an electroless Cu, Ni, Co and/or Ag metal plating bath containing the metal salt or salts and a reducing agent and this treatment may be followed by electro-deposition. The examples disclose photosensitive layers containing conventional benzene diazonium sulphonates which may also contain lactic acid, and cadmium and calcium lactates. Exemplified intensifying baths contain (a) CuSO 4  5H 2 O, Na 4  (ethylenediamine tetracetate), and formaldehyde; (b) ferrous ammonium sulphate, Fe(NO 3 ) 3 , citric acid, and AgNO 3  and (c) NiCl 2 . 6H 2 O or CoCl 2 À6H 2 O, NaH 2 PO 2 ÀH 2 O, and citric acid. The substrate may be saponified cellulose triacetate, polyethylene terephthalate, anodized aluminium, a polyimide, a glass fibre/epoxy resin or a paper-base laminate and may carry an adhesive layer of a polyester, or a butadiene/- acrylonitrile copolymer containing an alkaline phenol or cresol resin.

Title: Improvements in or relating to the chlorination of olefinic polymers
IPC: C08F8/20
Filed: 1940-08-14
Abstract: Chlorinated polymers of low molecular weight iso-olefines, e.g isobutylene and isoamylenes, which are heat stable and of good colour, are obtained by dissolving the polymer in a chlorine-resistant solvent, e.g. carbon tetrachloride, adding to the solution from 1 to 90 per cent of rubber by weight of the polymer and introducing chlorine at a temperature between atmospheric and 100 DEG C. and a pressure between sub-atmospheric and 100 lbs. per sq. in. The product may be isolated by precipitation with alcohol, ether or a ketone, or by treatment with boiling water or steam to drive off the solvent.  To obtain uniform products, chlorination is effected in the dark and under controlled conditions, as described in Specification 559,294; by raising the temperature the chlorine content is increased.  The products are suitable for lacquers, paints and coating-compositions; products of lower chlorine content are soluble in hydrocarbons and chlorinated hydrocarbons, while those of higher chlorine content are soluble in some oxygenated organic solvents; by choice of chlorine content, the material may be rendered compatible with natural or synthetic guns and resins. Examples are given of the treatment of polyisobutylene of low and medium molecular weight which is dissolved in carbon tetrachloride with various additions of rubber.

Title: Machine for packing cigarettes with inscriptions uppermost
IPC: B65B19/08
Filed: 1931-06-11
Abstract: 380,141. Arranging cigarettes for packeting. JAGENBERG, G. MEYER-, 107, Himmelgeisterstrasse, D³sseldorf, Germany. June 11, 1931, No. 13141/32. Divided on 380,129. [Class 94 (i).] The cigarettes are fed from a magazine on to a conveyer chain comprising grooved plates 62, Fig. 2. Opposite each groove a control key 65 is pivoted at 67 on a short arm. In the event of a cigarette lying incorrectly in its groove, the corresponding key is turned from the position shown in full lines in Fig. 2 to the position shown in broken lines. A plunger 68 transfers the cigarettes into sleeves 70 in a turning apparatus W, Figs. 2 and 3. A pinion 64 is mounted on the exterior of each sleeve and gears with one of a series of racks 71. Normally the racks are held immovable by the engagement of a bolt 72 in a slot 97, but if, owing to the incorrect position of a cigarette, a key 65 has been turned, a bell-crank lever 66, which normally occupies the position in full lines, and holds up the bolt 72, is prevented by the key from rising above the position shown in broken lines. This allows a spring 106 to disengage the bolt 72 from the slot 97, and a spring 73 draws the rack 71 to the left, Fig. 3, and turns the cigarette through 180‹ into correct position. Further movement of the plunger 68 feeds the cigarettes on to a plate 75, Fig. 4, pivotally mounted at 76. The plate tilts into an oblique position and an arm 77 arranges itself in parallelism therewith. A slide 80 is drawn to the right to collect the cigarettes into an overlapping group, and a pusher 78 descends and pushes the group over a plate 100 into a box, which is included to facilitate insertion. A resilient plunger presses the charge into position.
