Abstract: 1446936 Making electrical connections AMP Inc 8 Nov 1973 [14 Nov 1972] 51799/73 Heading B3A [Also in Division H2] Connection is made to the conductors 2 of a flat cable 4 by a plurality of conductive posts 20 secured in a block 18. The upper ends 44 of the posts have two pairs of teeth, the pairs being inclined towards one another at the top. The holes 66 in block 16 for the teeth are tapered to bias the teeth towards one another and the blocks are held together by latches 60. The teeth have their shoulders 22 set in one direction in one row of holes and in the opposite direction in the other row, thus staggering the connection points in adjacent conductors (Fig. 5 not shown). A jig (76) and a die (96, Fig. 7 not shown) are used to press the teeth through the flat cable. Studs 50 on the block 18 allow location of the block in the die which has an adjustable stop (88) for the cable. The die has rectangular bores (108, 108<SP>1</SP>, Figure 8 not shown) for receiving the teeth. The bores do not allow the teeth to part greatly as the conductor 2 passes between them and in consequence the conductor is deformed between the teeth (Figs. 9 and 10 not shown). The posts 20 may have sockets at their lower ends.

Abstract: 1,088,840. Bearings; linkwork. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. Dec. 24, 1964, No. 52449/64. Headings F2A and F2K. In a rectilinear-motion bearing for a manipulator which is operated by a lever so as to cause movement of a first member relative to a second member, or to cause movement of a second member relative to a first member, both the first and second members 1, 2 each have parallel grooves 5 or 6 which receive therein spacing members 9 so that relative universal sliding movement may be effected between the members 1 and 2. In an embodiment, the member 1 has three grooves 5 therein, the member 2 has two grooves 6 therein and the spacing-members 9 each consist of a tetrahedron of graphite or of other anti-friction material. A screw 15 is passed through a hole 10 in the member 1 and is screwablyattached to a member 14 which has a portion passing through a hole 11 in the member 2 and has a flange 16 positioned below the member 2. A ball-bearing 17 is positioned intermediate the flange 16 and a hardened insert 18 of the member 2. The latter is engaged by a sphere 25 which is fixed to a lever 26 and is received by a part-spherical surface 23 of a housing 21, which is attached to the member 2. In operation, either the member 1 or the member 2 is fixed and the other member is free to slide. When the member 2 is fixed, the movement of the lever 26 rotates the sphere 25 and the member 14, together with the member 1, is driven in an opposite direction to that of the lever 26. The movement ratio is determined by the diameter of the sphere 25. When the member 1 is fixed, the movement of the lever 26 causes the sphere 25 to roll along the member 14 and thus move the member 2 in the same direction as the lever 26.

Title: Apparatus for Bleeding Gases from Hydraulic Systems
IPC: B60T17/22
Filed: 1966-11-24
Abstract: 1,160,687. Hydraulic brakes; valves. ERNST HEINKEL A.G. 24 Nov., 1966, [7 Dec., 1965], No. 52622/66. Heading F2F and F2V. In an arrangement for bleeding gases (e.g. air) from hydraulic braking systems, a valve housing 3 is provided with a passage 33 through which an hydraulic fluid can flow in both directions, a cylinder 2 and piston 20 unit (e.g. a brake master cylinder 1) is connected with the housing for conveying the fluid through the passage in one direction via the channel 19, a check valve member 8 being provided in the passage which includes an apertured valve seat 6 and resilient means for biasing the valve member into sealing engagement with the seat to prevent flow of fluid in the other direction, valve actuating means, in the form of a screwed plug 12, being operative to move the valve member away from the seat and thus to equalize the fluid pressure at both sides of the seat. In operation, when the hydraulic braking system is in actual use, the screw plug 12 is screwed into the housing 3 and the pin 14 maintains the valve member 8 in an open position so that the pressure in the chamber 2 of the master cylinder 1 equals the pressure in the conduit 32 leading to the wheel brake cylinder 30. In order to expel air bubbles from the hydraulic circuit, the bleeder screws 31 on each wheel brake cylinder 30 are moved to an open position and the end portion 17 of the screw plug 12 is rotated to retract the pin 14 to the position shown in Fig. 2. Repeated pumping of brake fluid from a supply reservoir 22 through the channel 19 causes the fluid to open the check valve 8 by overcoming the bias of the spring 9 and any bubbles of air or other gas which are present in the hydraulic circuit are expelled in response to a few working strokes of the master cylinder piston 20. The bleeder screws 31 are then screwed tight and the screwed plug 12 is returned to its original position to leave the brake system free of gases and ready for renewed use. The check valve 8 is provided with spacer pins 10 which can abut against the end face of the nipple 4 to permit the brake fluid to flow freely between the master cylinder and the wheel brake cylinders during normal brake operation.

The coupler 20, Fig. 3, has an arcuate surfaced insert 26 and tapered portions 28 to permit horizontal and vertical movements relative to a pin 22 connecting it to the yoke 24. In operation, the coupler compresses the buffer 36 until a plate 34 abuts stops 38 on a housing 40 which then compresses the buffer 44 and operates the damper until stopped by abutment 46. The buffers 36, 44 are pre-loaded by bolts 48, 50 attached to the plates 42, 34. The hydraulic damper 56 has an orifice 72 and a smaller orifice 68 acting on the return movement, both orifices having a spring-pressed non-return ball-valve. On a return movement the yoke 24, which is moved clear of the damper in a compressive movement, engages the plunger 66 of the piston 62 anc moves the plunger 64 to compress the buffer 36.
