[Also in Division H1] A printed circuit board assembly comprises a plurality of metal sheets each having an insulating layer on opposite surfaces thereof and a plurality of conductors on each insulating layer, the sheets being mounted together in spaced relation, and connecting means being provided between conductors on different sheets. The sheets may be made of, or coated with, A1, Mg, Ti, Be, Zr, or alloys thereof, a surface of which is oxidized, by anodization or otherwise, to form the insulating layers; alternatively, the latter may be formed by spraying or evaporating insulating material on to the metal sheets. The conductors may be of Au, Cu or A1 and may be deposited by electroless or electrolytic plating, vacuum or vapour phase deposition, spraying, silk screening, or lithography, followed as necessary by etching or electron beam scribing. Plated through holes are used to interconnect conductors on opposite surfaces of a sheet, the hole walls being coated first with insulation unless a conductive connection to the sheet is required; such conductive connection may also be provided by omitting or removing the insulating layer from selected areas of the sheet surface before depositing the conductors. Double-sided printed circuit boards of the invention are stacked, Fig. 5, not shown, adjacent boards 15, 16 having registering stand-off portions 17, 18, 20, 21 which are bonded or riveted together to provide a space 19 between the boards. Conductors on adjacent boards are interconnected where required by metal plugs 23 soldered or upset in position in registering through holes in boards; such plugs may also be used to connect the boards mechanically. Fig. 4, not shown, depicts adjacent boards held together in spaced relation by rivets which are secured in registering holes in the boards and then welded together. An edge of a circuit board may be serrated to form projections 9, Fig. 2, which are completely covered by the insulating layer and carry conductive contacts to form plug-portions of a coupling arrangement; the serrations may be omitted. Alternatively, Fig. 3, the edge of the board at which connections are to be made is bent through a rightangle, plated through holes 10 being provided in the bent-up portion which are engaged by plug pins 11.

Title: Improvements in brake operating systems for vehicles
Inventor: WILSON ALEXANDER JOHN
IPC: B60T8/20
Filed: 1960-04-30
Abstract: 917,494. Fluid pressure brakes. GIRLING Ltd. April 24, 1961 [April 30, 1960], No. 15271/60. Class 103 (1). A brake fluid pressure control valve is moved in one direction by pressure acting on a member co-operating with a variable angle inclined plane and in the other direction by another pressure, normally the brake-actuating pressure. Compressed air from a reservoir, or another control unit, manually regulated acts on a piston 11 to move one arm 13 of a bell crank lever having a roller 14, bearing on an inclined plane 16, pivoted at the junction of the arms 13, 19. The inclination of the plane 16 may be varied by lever 18 either manually or automatically in accordance with vehicle load to vary the loading on a control valve element 21 produced by the piston 11. On brake application, pressure in line 10 moves the piston 11 and thereby valve 21 to open a valve 25 to admit pressure from line 29 to a port 31 connected to the brake actuator. Pressure in this port is transmitted by a passage 30 to act on a piston 22 rigid with the valve 21; the piston 22 having a greater area than piston 11, the valve 21 moves back until the valve 25 closes and the pressure in port 31 balances the pressure under piston 11 proportionally to the relative areas of the two pistons and the inclination of the plane 16 as determined by the position of the lever 18. On release of pressure in line 10 the pressure in port 31 moves the piston further back to allow venting of the port 31, and the brake actuator, through the bore 32 and radial port 33 of the valve 21. In modifications, the bell crank lever may be replaced by push-rods and the control piston by a diaphragm. The front brakes of the vehicle may be applied at line pressure and the rear brakes at a pressure as determined by a device as described in accordance with the load as measured by suspension movement.
