Title: Improvements in or relating to electroplating
IPC: C23F13/00
Filed: 1964-03-13
Abstract: In electroplating a metal cathode, selected areas are stopped off by placing them in intimate electrical contact with a metal of a lower hydrogen overvoltage than the cathode and chosen from Pt, Pd, Rh, Ir, and Ni.  These metals may be placed in intimate contact with the selected areas by chemical or electrolytic plating, spraying, brushing, contacting or dipping or by application of ionic solutions of the metals made into a paste with inert fillers, or by placing a thin foraminous sheet of or coated with the metals immediately adjacent and electrically in contact with the selected areas.  As described the outside of a steel pipe is coated with chromium from a chromic acid bath containing sulphuric acid except at the end which is chemically coated with platinum.  In another arrangement, a mandrel is uniformly coated over the whole of a selected length with chromium from a chromic acid bath containing sulphuric acid and potassium silicofluoride by attaching two guard rings over one end of the mandrel, that nearer the outer end being coated with the stopping off metal.  On removing the rings after plating the mandrel coating is of uniform thickness.  Plating racks may be treated with the stopping off metal to prevent build-up of deposited metal on repeated use.  Reference is made to using the invention in electroplating with nickel, copper, tin or zinc.

Abstract: 1,085,559. Surgical clips. PARKE, DAVIS & CO. March 11, 1966, No. 10929/66. Heading ASR. A surgical clip 10 comprises jaws 12, 22 made of or coated with a metal which is low in the electromotive series, e.g. silver, the jaws being interconnected by means, e.g. an apertured rivet 36, of a metal or alloy which is relatively highly placed in the electromotive series, e.g. alloys of aluminium or magnesium, so that when the clip is placed in the body it forms a galvanic couple with body fluids present and the rivet will disintegrate to release closing pressure on the jaws before the jaws disintegrate. Disintegration of the rivet occurs after a time determined by the material chosen. Each jaw has prongs 18, 28 for engaging body tissue and holes 20 for receiving holding prongs 50 (Figure 3, not shown) of a clip applicator.

Title: Labelling machine
IPC: B65C9/18
Filed: 1962-03-22
Abstract: 973,660. Labelling machines. W. RALSTON & CO. Inc. March 22, 1962 [March 23, 1961 ], No. 11052/62. Heading B8F. [Also in Division B6] A labelling machine of the type in which the labels 22 are mounted on a tape 20 comprises a label applying plunger 30, a label detecting and separating station 32, and a tape drive assembly 34, the tape 20 being transferred from a supply reel 16 to a wind-up reel 18. The tape 20 passes around a roll 36 and between the bite of rolls 38, 40, the axis of the former being offset from the latter in the vertical direction so that the labels are straightened in passing through the bite. The resistance to rotation of these rolls also keeps the tape taut. The tape 20 is then guided by a roller 41 and leaf spring 64 through the detecting and separating station to a roll 50 and a driving mechanism comprising the bite between a driven roll 52 and a spring pressed, toothed roll 54. The plunger 30 is mounted in the machine for vertical reciprocation, this being effected by a driven crank-shaft 128, a crank 126 and a connecting rod 132 pivotally connected at its ends to the crank 126 and plunger 30. The connecting rod 132 consists in two telescopic members held together by a spring pressed ball detent so that when the plunger 30 engages the article to be labelled the members may slide with respect to each other while the crank continues its rotation. The plunger 30 includes a head 100 which comprises two metal tubular members 108, 110 clamped together by a screw, and a sponge rubber tubular member 112 covered by a plastic sheet 114, the head being sealed into plunger tube 102 by an 0-ring 109. A label is held on the plunger head by drawing air from the plunger 30 through tubes 122, 123 using a pump, the pumped air being passed through a tube 45 and nozzle 46 to support the label from below. In a modification (Fig. 5, not shown) the head which possesses a filter within its bore is held in tube 102 by a coiled spring. The detector and separating station 32 is provided with a heater 49 and a feeler element 74 (not shown) pivotally supported about a horizontal axis on an arm 70 of a microswitch 66. The element 74 comprises a generally cubical component having grooved faces which, when one of its edges engages an edge of a label, subsequently rotates through a 90 degrees angle. In its rotation its horizontal axis firstly rises then falls, microswitch 66 being triggered in the former movement. An automatic cycle of operation is controlled by the microswitch 66, two further microswitches 216, 218 mounted on the crank-shaft and two relays. In a cycle a label already mounted on the plunger is applied to an article, a further label is then fed on to the plunger and the next label is detected, the tape drive being stopped when the feeler element 74 (not shown) has completed its 90 degrees rotation.

Abstract: 1384951 Semi-conductor devices BBC BROWN BOVERI & CO Ltd 9 March 1972 [11 March 1971 20 July 1971] 11148/72 Heading H1K A semi-conductor device is mounted between two thrust members on which bear two spring biased rigid pressure members and on each side of the device the contacting surfaces of the thrust and pressure members have different radii of curvature, the smaller radius of curvature being sufficiently great that rolling motion can take place during the application of a clamping force. As shown, Fig. 2, a semi-conductor device 7 secured between carrier plates 8, 8<1> which may be of Mo is positioned between a pair of thrust members 5, 6. Pressure members 1, 2 are urged towards one another by spring loaded bolts 10, 11 and apply pressure to domed surfaces on the thrust members 5, 6, which can roll to ensure that the pressure is applied evenly across the device. Members 5, 6 also act as cooling members and may contact the carrier plates 8, 8<1> through ductile foils 9, 9<1>. Layers 23, 24 of titanium carbide, a polyamide or other suitable plastics material may be applied to the pressure members 1, 2 to provide a friction brake surface which, together with resilient members F1, F2 provided on the edges of the pressure members 1, 2, protect the device against lateral impacts. Alternative configurations of the pressure transmitting surfaces between the thrust members and the pressure members are illustrated in the insets A, B and C. The ball shown in variant C may be replaced by a lens shaped body. A stack of semi-conductor devices and thrust members may be arranged between the clamping members.
