Title: Method to produce printed circuits
IPC: H05K3/10
Filed: 1968-07-25
Abstract: 1,208,337. Printed circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 25 July, 1968 [29 Aug., 1967], No. 35541/68. Heading H1R. [Also in Division C7] In the manufacture of a printed circuit board in which conductors and plated through holes are formed by deposition of copper electrolessly and by electroplating and etching the desired conductor pattern metallic complex salts are added to the electroless plating bath. A substrate, after coating with a thermoplastic glue layer and perforating, is mechanically roughened and then seeded by an activating solution. The thus prepared substrate is then placed in a copper electroless plating bath to which has been added metal complex cyanide salts to stabilize the bath and prevent the formation of Cu 2 O. After electrolessly plating copper on the surfaces of the substrate and holes a negative lacquer resist is applied to the substrate to leave exposed those areas corresponding to the required conductor pattern and the hole walls. These exposed areas are then reinforced by means of a copper electroplating bath. After removing the resist layer the substrate is subjected to an alkaline etching bath which removes the electroless plated portions not reinforced and a small portion of the electroplated copper thereby leaving the required conductor pattern and plated holes. The substrates may be coated with a solderable protective lacquer, or an electroless coating of a corrosion protective metal. Precious metals may be applied to the electroplated copper. Suitable electroless copper plating baths are:-(1) 15 g CuCl 2 .2H 2 O, 40 g KNaC 4 H 4 O 6 , 13 g free NaOH, 11 g formaldehyde, 0À05 g K 2  [Ni(CN) 4 ]; (2) 10 g CuCl 2 .2H 2 O, 56À5 g KNaC 4 H 6 O 6 , 14À7 g free NaOH, 12 g formaldehyde, 0À5 g K 4 [Fe(CN) 6 ]; (3) 10 g CuCl 2 .2H 2 O, 56À5 g KNaC 4 H 4 O 6 , 10 g free NaOH, 8-7 g formaldehyde, 1À3 g K 4 [Fe(CN) 6 ], 0À6 g K 3 [Cu(CN) 4 ]. Reference has been directed by the Comptroller to Specification 1,145,578.

Abstract: 325,912. Consolidated Brake & Engineering Co., Ltd., and Palmer, B. W. Dec. 13, 1928. Fluid-pressure; hand or foot actuation.-In brake apparatus comprising two independent brakes each operating a separate set of shoes, one brake being operated by hand or foot, and the other by suction or compressed air, the control valve 8 of the air-brake is operatively connected to the pedal or lever through the medium of a normally stressed spring 24 so that the valve is actuated immediately movement is given to the lever or pedal of the hand or foot actuated brake without causing an actuation of the latter, the spring being further stressed before the manual or foot brake can be applied. The levers 3, 3, 7, 7, of the fluid-pressure brakes are actuated by pistons or diaphrams 6, 6, 5, 5, connected through the control valve 8 to a vacuum cylinder 9, the vacuum of which is maintained by the induction of the engine 10 through a non-return valve 11. The spindle 23 of the valve 8 is connected to the rod 16 of the brake pedal 12 through a spring 24 as described in Specification 320,739. The spring 24 is stressed approximately to the force tending to close the valve 8. The rod 17 of the hand-brake 13 and the rod 16 of the foot-pedal 12 are connected through elongated slots to pins on arms 15, 14 secured on a cross-shaft 18, the arm 14 being connected by a rod 19 to an arm 20 on a cross-shaft 21 by which the Levers 4, 4 of the hand or foot brakes are operated. The first part of the movement of the pedal 12, by which the fluid-pressure brake is operated, only takes up the slack in the brake rigging and brake shoes operated by the hand or foot brakes. In this part of the movement the valve for effecting the release of the brakes is closed and the spring 24 moves bodily with the rod 23 without being stressed. Further movement opens progressively the brake application valve and stresses the spring 24 until equilibrium is reached between the brake cylinder pressure and the pressure of the spring whereupon the brake application valve automatically closes and holds the brakes on. In the case of a compressed air brake the control valve may be as shown in Specification 306,635.

Title: Improvements in or relating to devices for selecting and transforming time phase modulated pulse trains
IPC: H04J3/04
Filed: 1954-12-22
Abstract: 765,238. Multiplex pulse signalling. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 22, 1954 [Dec. 23, 1953], No. 37121/54. Class 40(5) A circuit for selecting a particular channel of a multiplex time-phase modulated pulse train and producing a duration modulated pulse train consists of a triode -1 which is normally non-conducting (see below), incoming signal pulses being applied to the grid via condenser 6 and negative gating pulses being applied via transformer 8 to the cathode. The gating pulses are arranged so that the selected channel pulses fall within the gating period. The pressure of a gating pulse causes the valve to conduct. A positive pulse of the selected channel causes grid current to flow which charges condenser 6 negatively. The cessation of the channel pulse then causes the grid voltage to drop far enough to cut off the valve (despite the continuation of the gating pulse) and so terminate the duration modulated output pulse. With the end of the gating pulse, the grid/ cathode voltage falls further negative, and then rises slowly as condenser 6 discharges through resistor 4. The time constant of 4 and 6 is chosen so that the valve remains cut off until the next gate pulse.
