Title: Improvements in and relating to Connections to Solid State Devices
IPC: H01R12/71
Filed: 1967-03-09
Abstract: 1,162,184. Semi-conductor devices; printed circuit assemblies. INTERNATIONAL BUSINESS MACHINES CORP. 9 March, 1967, No. 11043/67. Headings H1K and H1R. Monolithic or integrated semi-conductor devices are gold-coated on their lower surfaces and hot pressure bonded to superposed gold and chromium layers at the bottom of cavities in a substrate of glass or ceramic (e.g. 96% alumina). The cavities are formed by pressing the green ceramic or by bonding an apertured alumina sheet to an alumina blank. Each device has a plurality of built-up contacts extending through a protective glass coating on its upper surface and these lie in substantially the same plane as lands on the top surface of the substrate and which consist of aluminium, copper, or one or more noble metals. (For example the lands may have superposed gold, copper, and chromium layers). A plate is provided with conductive tracks suitably placed to interconnect adjacent contacts and lands. Suitable plates are aluminium or copper foils, paper, resin-reinforced fibrous materials, tetrafluoroethylene resins, polyethylene-terephthalate resins, and polyimide resins. The conductive tracks are formed on these, preferably on an intermediate acrylate resin parting layer, by laminating and etching, or by masked evaporation and may consist of aluminium, copper, or one or more noble metals. (A track may have superposed gold, lead, tin and copper layers). Preferably the plate is transparent so that visual alignment may be used in the bonding process, and is preferably insulating so that interconnection tests may be made before bonding. The backing may be clamped to the devices and substrate on a hot stage (which may have orienting pegs engaging the backing) and the assembly bonded by a solder reflow technique using lead-tin solder. Instead, single or multi-tipped thermocompression bonding machines may be used, the tips penetrating the backing during bonding. If ultrasonic bonding heads are used these are first heated to penetrate the backing and ultrasonic energy then supplied to affect the bonding. Laser or electron beam bonding may be used instead. The bonding layer is pulled away from the bonded contact tracks and lands, any parting layer being dissolved away. Alternatively the backing plate may be multilayered and consist of polyimide sheets bearing conductive tracks formed by masked evaporation or electrochemical deposition. Through-holes in the backing are metallized to provide interconnection between tracks in the various planes. Such a backing plate remains in place after bonding to interconnect the devices on the substrate.

Title: Improvements in or relating to brake systems for motor vehicles
Inventor: DUNN MICHAEL RONALD DAVID
IPC: B60T8/26
Filed: 1960-03-31
Abstract: 917,175. Hydraulic braking systems. FORD MOTOR CO. Ltd. March 14, 1961 [March 31 1960], No. 11444/60. Class 103 (1). [Also in Group XXIX] An hydraulically-operable braking system for a motor vehicle includes a device for varying the pressure supplied to a brake-applying means of either the front or rear wheels for a given pressure in a master cylinder and which comprises a differential area piston which is biased by a leaf-spring of variable effective stiffness to vary the output pressure corresponding to a given input pressure, e.g. in dependence on vehicle load. As shown, the pressure supplied to the front brakes is augmented by a differential piston 3 arranged to provide different pressures in chambers 2, 16 in dependence in part upon the difference in area of opposite faces of the piston and in part by the biasing effect of a leafspring 7 acting on a plunger 6 engaging an extension 4 of the piston. The biasing effect of the spring is variable by means of a link 21 having a roller 19 on its end which acts as a fulcrum for the spring, the link being movable axially by means sensitive to the load on the vehicle. Two rollers may be used in place of roller 19 (Fig. 2, not shown), one engaging the spring and the other the housing of the device. The link 21 is connected to a bell-crank 24 secured to shaft 25 of a damper 26 on the sprung part of the vehicle and connected via a rod 27 and springs 31, 32 to the front or rear axle, so that as the latter rises and falls with changes in the load the link 21 is moved to shorten or lengthen the effective length of the spring 7 to vary the force it exerts on the piston 3, and thereby vary the pressure supplied to the front brakes. The springs 31, 32 and damper 26 are arranged to prevent transient movements of the axle being transmitted to the link 21. A limiting valve 9, urged by a spring 10 to open a by-pass nullifies the effect of piston 3 when the pressure in the master cylinder falls below a predetermined value, so that initially or on light braking the pressure supplied to front and rear brakes is equal, the valve 9 closing with heavier braking so that pressure supplied to the front brakes is subsequently higher than that supplied to the rear brakes. Where the pressure varying device is used on a vehicle with pneumatic suspension, the link 21 may be moved by a piston acted on by the pressure of the air used to maintain a constant riding height.

Title: Improvements in or relating to coating compositions
Inventor: CHATFIELD HERBERT WALTER
IPC: C09F9/00
Filed: 1948-04-23
Abstract: A coating composition is based on a vegetable or animal drying oil containing an aluminium alcoholate, the alcohol radicle of which contains at least four carbon atoms.  The oil may be a blown oxidized or partly polymerized oil, e.g. blown linseed oil, and the alcoholate is preferably obtained by reacting dry aluminium at 100 DEG  to 200 DEG  C. with a dry alcohol, e.g. butyl, heptyl or octyl alcohols.  A solvent, e.g. white spirit, may also be present.  The presence of the alcoholate in amounts less than 25 per cent of the weight of the oil causes the latter to gel more rapidly.  Specification 573,083, [Group IV], is referred to.

Abstract: 494,014. Circular knitting-machines. CLARKE, A. V. April 20, 1937, No. 11281. [Class 74 (ii)] Driving means for fabric draw. off mechanism comprises two shafts 34a, 34b which are coupled together by sleeves 35a, 35b. On sleeve 35b is a spiral groove 39 which receives one end of a pin 38 the other end of which is received in a radial slot 36 in the sleeve 35a. During rotational knitting the pin 38 abuts against a spring 40 at the end of the groove 39 and drive is thus transmitted from shaft 34a to shaft 34b and so to the draw-off mechanism A. When the shaft 34a oscillates during oscillating knitting the pin 38 travels freely around the groove, away from the spring, and back again, and oscillation is not imparted to shaft 34b. The groove may be replaced by raised ribs. The draw-off mechanism A forms the subject-matter of Specification 494,104. Specification 343,534 also is referred to.
