IPC: B60T13/52
Filed: 1969-10-29
Abstract: 1,258,820. Anti-skid braking systems. KELSEY-HAYES CO. 29 Oct., 1969 [9 Dec., 1968], No. 53078/69. Headings F2E and F2F. A skid control braking system comprises modulating means having fluid inlet and outlet portions and adapted to control the fluid pressure applied to the brakes of at least one wheel of a wheeled vehicle from a source of brake actuating fluid in accordance with signals received from means for sensing an incipient skid condition of the wheel, sensing means for sensing the differential pressure conditions between the fluid inlet and outlet portions of the modulating means, and indicating means, pro viding a signal, for the vehicle operator, to indicate actuation of the sensing means. As shown, a pedal-operated master cylinder 20 communicates hydraulic fluid pressure via conduits 24, 34 to front and rear brake wheel cylinders 16, 18, the rear brake drums 14 having associated therewith exciter rings 42 and sensors 40 which produce electrical signals according to the rotational velocity of the rear wheels and for transmission to a control module 38 connected to the modulating valve assembly 36. The latter comprises a vacuum chamber and housing 48 divided by a diaphragm assembly 50 and having mounted thereon an hydraulic cylinder housing 52, and a solenoid mechanism 56 which, upon receipt of a signal from the module 38 indicating a skid condition, is energized to create a differential pressure in the housing 48 to move the diaphragm assembly 50 and an hydraulic piston 54 whereby a check valve 64<SP>1</SP> is seated to cut off further application of the master cylinder pressure to the rear brake cylinders 18. Malfunction of the valve assembly is signalled to the vehicle operator by a device having bores 70, 72 housing pistons 71, 73 and connected by conduits 82, 76 with the conduits 32, 34, the piston 73 having an annular groove 114 in which is normally engaged the plunger 110 of a switch 98; when the piston 73 is moved to the right the plunger is biased upwardly to complete the circuit to a lamp 100; alternatively, an audible signal is given.

Abstract: 1,267,021. Laying underwater pipe lines; pipe couplings. BROWN & ROOT Inc. 24 March, 1970 [18 April, 1969], No. 14103/70. Headings F2G and F2P. Two pipes 18, 24 are coupled underwater by telescoping their ends, providing a dry working space around the telescoped portions which are then cut away, and connecting the newly exposed ends. A flexible pipe 24 fitted with an end cap 32 and lug 34 is force fed through a wheeled tension unit 25 on a lay barge 22 on to a pontoon 28. The pipe 24 is then pulled towards, and later into telescopic engagement with, an alignment funnel 20 around the foot of a riser 18 by means of a drawline 36 attached to the lug on the pipe 24. The drawline 36 is threaded through the riser 18 and tensioned by an engine 38 on the platform 10, as shown, or on the lay barge 22, movement of the pipe 24 being controlled by the tension unit 25 and gradual lowering of the pontoon 28 being caused by the increasing moment exerted by the extending pipe 24 or controlled flooding of the pontoon or both. A diving bell (44), Fig. 4A (not shown), is lowered with a supply pipe (46) from a work barge (42), Fig. 4 (not shown), to surround the telescoped portions of pipe; the pipes 18, 24 are clamped to the sides of the habitat which are then sealed, and air, nitrogen &c., is passed through the supply pipe to fill the diving bell. Divers are lowered in a chamber (50) to enter the habitat through an excavation (48) beneath, to cut away the telescoped portions of the pipes. The atmosphere is changed if necessary to be highly nitrogenous and a connecting element (54), Fig. 5 (not shown), is welded between the pipes. The pipe 24 may be blocked at or prior to the cutting operation by a yieldable spherical plug (60), Fig. 4 (not shown), to prevent escape of gas from the diving bell and which is displaced by a higher pressure fluid later. If pipes 18, 24 are of equal external diameter they are arranged to abut inside the funnel 20, Fig. 2A (not shown); however, an internal annular projection may be provided in the funnel to hold the pipe-line 24 if this latter has a smaller diameter. If the corresponding configurations of the pipes determine exactly how far one pipe will telescope into the other then these pipes may be marked where they are to be cut and the connecting element may be made in advance to the correct size.

Abstract: 1352332 Sample weaving looms WOOL INDUSTRIES RESEARCH ASSOCIATION 30 April 1971 [3 Feb 1970] 5002/70 Headings DIE and DIM In a loom for weaving squares of fabric as samples, a rapier 44 is reciprocated along a path 14 to draw successive yarns from a package supply through healds 12 and reed 13 arranged on a frame 11, the frame 11 being traversed transverse to the path 14 in the direction A to produce a warp sheet and the frame 11 is then rotated through an angle e.g. 90‹ relative to the rapier and supply package so that the rapier can act as a weft inserter and draw wefts from the same supply package. Four supply packages (21-24) Fig. 3 (not shown) are used any one of which may be moved at a time under the control of a patterning device to present yarn to the rapier.  Presenting weft Fig. 5. When the rapier reaches to opposite side of the frame where the yarn is held transversely to its path by pneumatic piston operated grippers 33, arms 36, 37 on a piston operated pivotable arm 38 are moved towards the yarn to push it into spring loaded hook jaw 45 of the rapier. As the rapier retracts, grippers 33 release the yarn end and the yarn runs through guide eye 31 and the jaws of piston operated scissors 42. When the rapier reaches the other side of the frame, the grippers 33 move, under the control of piston 35 to grip the yarn between guide 31 and scissors 42 which then operate to cut the yarn, grippers 53 thereafter moving back to their original position. The same apparatus and procedure is used both when the rapier is forming the warp sheet and inserting weft. When the rapier reaches the opposite side of the frame a wedge member (61) descends and raises spring loaded jaw member 53 to release the yarn. Tensioning yarns. The side members (91, 92) Fig. 9 (not shown) of the frame 11 are coated with adhesive and as the rapier lays the yarn across them piston operated bars (93, 94) descend to press the yarns against them. Threading healds and reeds. Healds are taken individually from a row 74 by a rotating member 70 with a progressively widening thread 71 which moves the healds transversely and rotates them through 90‹ to a position 75 where they are aligned with the rapier 44 which is of such a shape as to be able to pass through the heald eyes 76. The reed 190 is mounted on rollers (191-197) Fig. 10 (not shown) so as to be movable transversely of the sley to align successive dents with the rapier.  Beating-up. The sley (199) is oscillated by means of a reciprocating pneumatic cylinder (203).  Shedding. Heald frames are guided by cords 83 running over pulleys 81, 82 and operated by a pneumatic cylinder 84 controlled by a punched tape device.

The line 15 is connected to the fuel supply line 9 via a restrictor 16 and to a chain 18 via a restrictor 17. A restrictor 14 may be interposed between the line 15 and the chambers 11, 12, 13. If any of the diaphragms are ruptured, the resultant change in pressure in the chambers 11, 12, 13 is sensed by a pressure gauge 19 which then produces a signal. In addition, if the ruptured diaphragm is one of those bounding either of the chambers 7, 8, whereby the pressure change is an increase, the resultant downward force on the rod 2 due to the bottom diaphragm of the chamber 11 being of larger area than the top diaphragm causes the rod to move to decrease the fuel supply.
