Patent GB-1321345-A (GB)
Title: Machines for the creation of mechanical shocks on a sample or  specimen undergoing tests
IPC: G01N3/30
Filed: 1971-11-25
Abstract: 1321345 Shock testing COMMISSARIAT A L'ENERGIE ATOMIQUE 25 Nov 1971 [9 Dec 1970] 54712/71 Heading G1S A pneumatic machine for generating mechanical shocks comprises a movable cylinder 8 having a top closure member 9 constituting a test sample carrying platform and a bottom closure member 10 through which the piston rod 21 of a piston 19 passes, a fixed member 2 having bearings 15, 16 guiding the cylinder 8 for axial movement and having an impact member 25 for the bottom 24 of piston 21 and a sleeve 29 in the fixed member which is engaged by a shoulder 32 on the cylinder. The chambers 34 and 35 respectively below and above shoulder 32 external of the cylinder 8 communicate through channels 36, 38 and valves 37, 39 with a source of fluid pressure. Chamber 34 communicates through a narrow channel 40 with the internal chamber 27 above piston 19 and this communicates through orifices 28 in the piston with the chamber 26 below the piston. In use, a first pressure is applied to chamber 35 and a second higher pressure applied to chamber 36 and thence via channel 40 to chambers 26 and 27, thus causing cylinder 8 to move to its uppermost position in the fixed member 1, and the piston to move to its lowermost position in the cylinder. Valve 41 is then operated to quickly release the pressure in chamber 34, the pressure in chamber 27 being unaffected because of the fineness of channel 40. The cylinder 8 then moves downwardly under the action of the pressure in chamber 35 and the piston rod strikes the impact member 25. Thereafter the piston rises in the cylinder, and the air flows from chamber 27 to chamber 26 through orifices 28 so that the rise in pressure in chamber 26 is controlled by orifices 28. The net decelerating force on the cylinder 8 at any instant after the impact of piston rod 21 is the resultant of the fluid pressure forces on the top and bottom closure members and is thus controlled by the orifices and the initial pressures. The deceleration profile of the shock may be saw-tooth, rectangular, trapezoidal or semi-sinusoidal, the latter being obtained by interposing a spring between the piston rod and the fixed body. The orifices may be adjustable or may be partially or totally closed off.

Title: Valves for pressurised dispensers
IPC: B65D83/14
Filed: 1974-12-18
Abstract: 1470013 Pressurized dispenser valves AEROSOL INVENTIONS & DEVELOPMENT SA 3 Dec 1975 [18 Dec 1974] 54743/74 Heading F1R Opening movement of a dispenser valve is prevented when the container is in an upright position by means which obtrude into the path of movement of the valve but which moves aside under the action of gravity when the container is tilted. As shown the valve has a peg 9, axial movement of which is obstructed by a ball 13 lying on the downwardly convergent floor 11. Tilting the container allows the ball to roll clear of the peg 9 and the valve may then be opened and held open when the container is returned to the upright position. In place of the convergent floor, tracks necessitating tilting in a set direction may be used. The obstruction may be disposed in the valve housing itself and the valve may engage the obstruction directly.

Abstract: 1,168,928. Coiling ropes and rope like material. KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 18 Dec., 1967 [21 Dec., 1966], No. 57288/67. Heading DIT. To coil cable or rope-like material 1 into the storage cask 12, the material 1 is wrapped around a stationary disc 8 so as to wind a plurality of turns thereon, these turns being gradually pushed down the disc 8 by a swash plate 7 rotating with a disc 4. To ensure an accurate run-off point from the disc 8 the lowermost turn of material on the disc 8 is supported by a plurality of elements 10 carried by the revolving disc 4 and arranged in a stepped or staircase-like manner about the disc 8. The lowermost element 10 in the "staircase" is diametrically opposite the point at which the material is fed onto the disc 8 by a wheel 6 revolving with the disc 4. In Fig. 1 the elements 10 are rings carried by rollers 9 that are resiliently biassed towards the disc 8. In operation only the lowermost turn of the material on the stationary disc 8 can be forced off by the swash plate 7 since as soon as this turn has been forced past the elements 10, the elements 10 will move radially inwards to support the remaining turns. To reduce the height of fall of the material 1, further guide rollers 14, 15, 16 may continue the staircase-like path formed by the rollers 9 and elements 10. In Fig. 2 (not shown) the above described rollers 9 and discs 10 are replaced by fingers (19) radially displaceable against spring means away from the stationary disc 8, these fingers (19) being tapered on the surface thereof engaged by the turns on the disc 8 such that thel owermost turn can force it way past said fingers. In a further embodiment the supporting elements 10 are replaced by ball or roller bearings. To obtain a rosette-like laying in the cask 12, there may be a cylinder 18 below the stationary disc 8, then cylinder being rotated at a speed slower than the disc 4 and being provided with an eccentric deflector 18.

Abstract: 1414674 Fuel injection pumps ROTO DIESEL 14 Dec 1972 [22 Dec 1971] 57797/72 Heading F1A In a rotary distributer fuel injection pump having plungers 16 reciprocated in a transverse bore 15 in a rotary member 11, the outward excursions of the plungers being determined by the abutment of roller shoes 17 with the ends 28 of a stop in the form of a leaf spring 26 fixed to the member 11, the engaging portions of the shoes 17 and the ends 28 are shaped such that a given relative axial movement therebetween, e.g. at start-up, causes an increase in the permitted excursions and thus excess fuel delivery. The engaging surfaces of the shoes 17 and the ends 28 are provided with a series of complementary teeth and recesses. In the excess fuel delivery position shown, the teeth enter the recesses. After start-up the delivery pressure of a feed pump 12 increases and displaces a piston 36. This causes pivoting of a spring-loaded latch member 35 to a position in which it allows springs 33 axially to move a disc 31, rods 30, channel members 29 and the shoes seating in the latter. Before start-up the shoes are moved into the excess fuel position (shown) by a member 37 or a centrifugal governor 41 controlling a throttle 25 between the feed pump 12 and an inlet passage 24. In a further embodiment, Fig. 7 (not shown) the shoes are loaded by a spring (43) to the excess fuel position, fluid operated pistons 44 being provided for overcoming the spring (43) and thereby reducing the permitted excursions of the pistons 16 after start-up. Further movement of the pistons 44 displaces the shoes against the combined action of the spring (43) and a further spring (46), the shoes then co-operating with contoured stops which determine the maximum fuel delivery during normal operation. By providing the shoes in an element (50) slidable in oblique slots (52) in the distributer 11, axial movement of the element (50) changes the timing as well as the outward excursions of the pistons.
