Abstract: 1,264,878. Coating. RCA CORPORATION. 12 Dec., 1969 [27 Dec., 1968], No. 60678/69. Heading B2E. [Also in Division H1] Conductive material is applied to a non- conductor for use in the formation of a printed circuit by applying a layer of a resinous mixture to the non-conductor, the mixture comprising a resin solution having particles dispersed therein, the resinous portion of the mixture being adhesively compatible with the non-conductor, drying the mixture, leaching all of the particles from the mixture to render the layer micro-porous and subsequently depositing the conductive material on the microporous layer resulting in improved adhesion between the non-conductor and the deposited conductive material, The particles may comprise salts and/or starches and may be removed by leaching. A printed circuit may be formed by selectively applying the resinous mixture to the circuit substrate in the configuration of the desired circuit pattern, drying the mixture and leaching out the particles therefrom, masking off the portions of the substrate not coated with the mixture, electrolessly depositing a thin layer of conductive material within and upon the microporous structure, and electrolytically depositing a layer of conducting material upon the electrolessly deposited layer. Alternatively, the micro-porous layer may be formed over the whole of the circuit substrate, a thin layer of conductive material electrolessly deposited within and upon the microporous layer, a pattern impervious to the deposition of conducting materials or a mask then being applied upon the layer of conductive material and another layer of conductive material electrolytically deposited on the unpatterned portions to form the desired circuit, the pattern or mask removed and the portions of the conductive layer previously coloured removed. In the examples the circuit substrate is a phenolic laminate.

Abstract: 1,265,684. Fluid-pressure servomotor systems. UNITED AIRCRAFT CORP. June 26, 1969 [Aug. 12, 1968(2)], No.32262/69. Heading G3P. An aircraft engine bleed air system for airconditioning and pneumatic drives comprises a duct 14 having a valve 16 for controlling the flow through a heat-exchanger, means 40, 42 responsive to pressure in the duct for controlling the valve continuously and means 80, 82 responsive to temperature for controlling the valve continuously in response to temperature of the air discharged from the heat-exchanger. Changes in pressure act on a diaphragm 44 and adjust a flapper 56 in relation to a bleed pipe 60 containing a restriction 62 which creates a pressure difference across a valve actuator 18. The temperature responsive means adjusts a second flapper 100 to vary the pressure drop across a restriction 106 and hence the pressure applied to a diaphragm 46 acting on the first flapper. Stops 63 and 93 limit the adjustments in response to pressure and temperature changes and a spring arrangement 88, 92, 96 makes the temperature sensor independent of supply pressure variations.

Abstract: 1295436 Two-part couplings NIPHAN Ltd 26 Nov 1969 [2 Dec 1968] 57164/68 Heading H2E  One part 2 of a two-part coupling is provided with interlocking means coupled with a switch. The switch is closed when a shaft 3 is rotated clockwise; simultaneously a cam 4 on the shaft 3 forcing a rod 6 to the left against the action of spring 8. If the second part of the two-part coupling is not attached to the part 2, a member 11 pivoted at 12 to the end of rod 6 arid biased by a spring 14 into the position shown touches the wall of part 2 and prevents the switch from closing. If however the second part (16, Fig. 2, not shown) of the two-part coupling is screwed on to the part 2 shown by a coupling ring (17) this ring meets the cam surface 18 of the member 11 and causes the member 11 to pivot downwards so allowing the rod 6 to move to the left and the switch to be closed (Fig. 3, not shown). When the switch is closed a hook 10 on member 9 attached to the rod 6 locates behind a flange on the locking ring (17) and prevents separation of the coupling until the switch is opened. The working parts of the device are protected by a shroud 20 and the rod 6 is led out of the switch casing 1 through a sealing gland 7.

The bars 21 and 22 are slidable in the machine frame 16, 17 by drive means which includes a first coupling for producing similar axial movement of both bars 21 and 22 together and a second coupling for producing axial movement of one of the bars separately. The drive means includes a rotatable axially movable shaft 28 of which a first portion 32 has spaced circular grooves and a second portion 27 has a spiral groove, the portions meshing with a co-operatingly cut first and second pinion, 33 and 30, respectively. Rack and pinion action at the first portion 32 on rotation of the first pinion 33 causes axial movement of the shaft 28 which by rack-andpinion action at the second portion 27, causes simultaneous rotation of the second pinion. This causes movement of both tractors when knob 38 is rotated. Straight cut of the first pinion 33 and co-operating first portion grooves 32 allows rotation of the shaft 28 to drive only the second pinion 30. This causes movement only of bar 22 and therefore one tractor 13 when knob 31 is rotated.
