Title: Vehicle brake mechanism
IPC: B60T7/04
Filed: 1963-10-10
Abstract: 1,047,146. Master cylinders; foot operated pedals. KELSEY-HAYES CO. Oct. 10, 1963 [Nov. 1, 1962], No. 39961/63. Headings F2E and F2F. I n a vehicle braking system including a pedal lever 24 which may either operate a valve mechanism of a servo 10 to thereby actuate a master cylinder 15 or, in the event of the failure of the servo air supply to actuate the master cylinder by a direct mechanical connection, means 118 are provided to shift the pivot 30 of the lever 24, on failure of the servo supply, to provide for a greater pedal stroke to allow the mechanical operation. The means 118 (Fig. 3, not shown) comprises a piston 126 normally forced to the right by servo air supply pressure to maintain the rod 36, lever pivot pin 30 and lever 24 in the full line position of Fig. 1. On failure of the air supply a spring 131 moves the piston to the left when balls 145 carried in a flanged plate 142 attached to rod 36 rise from a piston groove to engaging a shoulder 146 of the cylinder to hold rod 36 against movement while lever 24 is operated. The servomotor (Fig. 2) comprises a piston 40 normally balanced by air pressure acting in chambers 61 and 63. Air supplied through ports 56 enters chamber 61 through port 62 in the axially movable member 50 and enters chamber 63 through passage 102, valve seat 73 and through passages 102, 86 and 85. Actuation of lever 24 moves the members 27, 98 to the left, valve seat 73 first abutting head 74 to cut off air supply to chamber 63, the valve 70 then moving to the left to open valve face 71, connecting chamber 63 to atmosphere through passages 85, 86 and 76-79. Piston 40 then moves left to actuate the master cylinder piston rod 43 and apply the brakes. Release of the pedal restores pressure in chamber 63 and spring 64 returns the piston 40. The passage 99 in member 74 allows the chamber 100 to the right of the diaphragm 96 to experience the pressure occurring in chamber 63, the differential pressures on elements 74, 97 providing " feel " reaction to the lever 24. When the pressure in chamber 100 drops sufficiently spring 105 is overcome and the diaphragm ferrule 104 abuts member 97 to provide increased reaction. On failure of servo air supply the operation of the lever 24 causes member 74 to move to the left and, after slightly deforming the seat 73, abuts the face of member 69 to move the members 50, washer 114 and piston 40 to the left to operate the master cylinder as before.

Title: Improvements in sintering process
Inventor: KNIGHT RONALD ANDREW
IPC: B22F5/10
Filed: 1958-12-22
Abstract: Uncompacted sinterable powders such as beryllium are sintered in the uncompacted state in a mould which has a core, such as copper, which has a melting point above the presintering temperature and below the sintering temperature of the powder, the powder being presintered until the mass is self supporting the temperatures then being raised to sintering temperature and the molten core removed from the mould. The beryllium powder is loosely packed under argon into a graphite mould dressed with an alumina or beryllia coating and the copper tube forming the core is coated with graphite and alumina or beryllia. Presintering is effected at 930 DEG C. to 1030 DEG C. and sintering at 1100 DEG C. to 1275 DEG C., both under vacuum.

Abstract: 1,131,210. Integrated circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 14 Sept., 1967 [16 Sept., 1966], No. 41991/67. Heading H1K. In an integrated circuit logic matrix of the type comprising a destructible coupling element, e.g. a fuse fs1-fs4, between each incoming conductor ce1, ce2 and each outgoing conductor cs1, cs2 to enable the matrix to be adapted to the performance of a desired logic function by selective destruction of the elements, the provi. sion of buffer elements such as amplifiers, inverters or impedance transformers between the outgoing conductors and the outlet connections cns1, cns2 of the matrix prevents direct electrical access to the coupling elements because of the danger of destroying the buffer elements. This difficulty is obviated according to the invention by connecting a switching element (a transistor T7, T8) in parallel with each buffer element (transistor T5 and resistors re1-re3 or transistor T6 and resistors re4-re6) so that when appropriate potentials are applied to current supply connections cna1-cna3 and to selected inlet connections cne1, cne2 and outlet connections cns1, cns2 a selected switching element shunts its associated buffer element and carries current to destroy a selected coupling element whereas when logic signals are applied to the inlet connections the switching elements are blocked and do not affect the operation of the circuit. The matrix is formed in a block of silicon, and aluminium is deposited on the surface of the block to form the incoming and outgoing conductors. The fuses consist of portions of the conductors having reduced cross-sections.
