Abstract: 1,063,548. Circuit assemblies. MESSWANDLER-BAU G.m.b.H. Aug. 27, 1965 [Aug. 28, 1964], No. 36832/65. Heading H1R. [Also in Divisions G1 and H3] The individual divider elements used in a divider network (see Divisions G1 and H3) comprise capacitors each consisting of three series-connected oiled paper condensers K1, K2, K3. Dielectric plates J are disposed between each two capacitors and a number of laminated resistors R1<SP>1</SP>, connected in parallel with each other, are arranged around each dielectric plate. Metallic coatings M1, M2 on plates J provide the series connection between the capacitors and resistors. The coatings may be of resistance material to serve simultaneously as ohmic resistors of the separate divider elements and protective coatings for the capacitors. The separate resistors R1<SP>1</SP> may then be omitted. In a modification, Fig. 3 (not shown), ceramic plate condensers may be used.

Abstract: 1444003 Web perforating apparatus AGFAGEVAERT 28 June 1974 [3 Aug 1973] 36897/73 Heading B4B A rotary perforating apparatus for perforating a travelling web of e.g. photographic film, comprises a frame 46, 47 in which a rotatable web-supporting wheel 10 is mounted, a plurality of web perforator assemblies secured to the periphery of the wheel and a rotary control member 13 to which are individually pivotally connected the ends of arms 73 each pivotally connected at opposite ends to respective punch carrier arms 62 of the perforator assemblies, rotation of the control member causing the carrier arms of successive assemblies to be actuated in order to perforate the web. The websupporting wheel 10 is secured to a shaft 27 rotatable, via a gear-wheel 52, in a stationary bearing block 29. The control member 13 is rotatably-mounted on the bearing-block and rotated at the same angular speed as the wheel 10 by means of gears 43, 58 and 54, the gear 54 meshing with a gear 53 keyed to the shaft 27. The axis 33 of the control-member is offset from the axis 32 of the wheel by an amount "e" thus causing the punch carrier arms 62 to be pivoted during rotation of the member, thereby causing punches 93 to be moved into and out of engagement with corresponding dies 65. The arms 73 are each connected at one end to the respective carrier arms by a ball-joint 74 and, at the other end, to the control member by a forked member 85 pivotally mounted in the member; the pivotal connection of the arm 73 to the forked member is provided by a pin 84 which may be eccentric such that by rotation of the pin, the depth of penetration of the punch into the die may be adjusted. A second control member together with the punch actuating elements is mounted in the opposite end of the wheel 10 (not shown in Fig. 2). Punched out slugs are removed from the interior of the wheel by suction via passages 71, 72.

Title: Improvements in and relating to the manufacture of printed circuits
Inventor: FLACK WOLF ISAAC
IPC: H05K3/18
Filed: 1957-12-03
Abstract: A printed circuit is formed by applying a resist to a metallic layer on an insulating support, leaving exposed the required conductor pattern, electro-plating a conductive metal on to the pattern, removing the resist and subsequently removing unplated parts of the metallic layer.  An insulated panel, in which any required holes have been previously pierced, has both faces of the panel and the walls of the holes coated with an adhesive lacquer, such as an elastomeric resin.  A sensitising solution containing 2% stannous chloride is then applied, followed by a coating of metal.  This latter coating may be applied by spraying on a solution of a salt, such as, silver nitrate solution containing ammonium hydroxide, and a reducing solution containing formaldehyde and sugar.  The temperature of the solutions may be conveniently controlled by passing them through U-tubes immersed in water, the temperature of which is thermostatically controlled. After cleaning and drying, a resist is applied to both surfaces to leave exposed the required conductor pattern.  The exposed part of the metallic layer is plated with a metal of good conductivity, preferably using a pyro-phosphate of the metal.  In one method the panel is immersed first for 15 minutes in a solution comprising:-  ..gm/litre .copper.25 .pyro-phosphate.175 .citrate.10 .nitrate.10 .ammonia.2 and secondly for 30 minutes in a solution comprising 240 gm/litre copper and 250 gm/litre sulphuric acid.  The deposited copper layer is overplated with a layer of tin in a suitable plating solution comprising, for example:-  ..gm/litre .stannous tin.55 .lead.25 .fluoboric acid.40 .mollasses.20 .glue.5 After plating the resist is removed by a suitable solvent and the panel cleaned in a water spray, leaving exposed the first metal layer.  This is then removed in a solution containing chromic acid and sulphuric acid, suitable proportions being 20% chromic trioxide and 10% sulphuric acid. p  Reference has been directed by the Comptroller to Specification 824,089.
