Title: Improvements in and relating to hydraulic shock absorbers
IPC: F16F9/18
Filed: 1944-08-04
Abstract: 584,952. Hydraulic shock-absorbers. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. Aug. 4, 1944, No. 14899. [Class 108 (iii)] [Also in Group XXXIII] In a hydraulic shockabsorber of the piston- and-cylinder type for use in aircraft alighting gear, relative movement of the piston 1 and cylinder 2 causes flow of liquid 'through an orifice 4 which is provided with a shutter 13 movable by an inertia mass 7 over a friction surface to restrict the effective area of the orifice in accordance with the vertical acceleration of the aircraft up to the instant when the shock-absorber comes into action, whereupon the shutter is pressed against the friction surface by the pressure of the liquid flowing in the shock-absorber. As shown, the inertia mass 7 floats on a spring 8 in a casing 6 fixed relatively to the cylinder 2, movement of the mass in response to violent accelerations of very short duration being damped by a dashpot 9, and the mass is connected by a lever to a rock shaft 11 which is journalled in the conduit 3 connecting the ends of the cylinder and is rigid with an operating finger 12. The perforated disc shutter 13 is mounted on a similarly-perforated friction plate 14 and is adapted to be rotated relatively to the plate by means of the end of the finger 12 engaging a recess or hole in the shutter offset from the centre. A flutter plate 16 having a central aperture 17 larger than the central apertures of the shutter 13 and plate 14 floats between the plate and an abutment 18. Operation. When the aircraft is descending at a steady speed, acceleration is zero and the inertia mass 7 presses against the spring 8 causing the lever 10 and finger 12 to move the shutter 13 into the position which permits maximum flow of liquid through the orifice 4. When the aircraft falls freely with downward acceleration, the mass 7 moves upwardly in the casing 6 and causes the lever 10 and finger 12 'to rotate the shutter so that its perforations do not register with those in the plate 14, and when the shock-absorber comes into action and liquid commences to flow, the shutter is pressed, in its set position, against the friction plate 14 by the pressure of the liquid until rebound occurs. Thereupon, the flutter plate 16 is pressed against the underside of plate 14 closing all the perforations therein except the central one, so that rebound is damped to a greater extent than the initial shock. The device may be modified to provide for further opening of the orifice by continued rotation of the shutter in the opening direction beyond the position corresponding to zero acceleration of the descending aircraft. The Provisional Specification also describes a construction in which the orifice is formed in the piston and the inertia mass is carried by a part rigid with the piston.

Abstract: 551,232. Powder metallurgy. BRITISH PISTON RING CO., Ltd., TWIGGER, T. R., and JUDD, J. A. Nov. 28, 1941, No. 15324. Drawings to Specification. [Class 82 (i)] [Also in Group XXII] In the manufacture of piston rings from powdered material the characteristic shape is imparted 'by a heat-pressing operation after the pressing and during or prior' to sintering. Rings are first produced by pressing and then split expanded by the insertion of a gap piece between'the ends and heated to set the ring. into expanded form. If 'the setting temperature is insufficient to cause sintering the ring next passes to a hotter zone to effect this. In a modification the operation is avoided by pressing the ring in an annular device having a ridge piece to produce the gap. The shape may be imparted by expansion of the formed mandrel or by constraint in a jig in each case with axial pressure if desired. Specification 538,679, [Group XXII], is referred to.

[Class 27.] Testing edge of coin for milling.-In coin-selector mechanism for coin-freed machines wherein a member, having a pin-and-slot mounting, in the coin path is capable of pivotal movement when engaged by a milled-edged coin to allow the latter to pass and of a lateral displacement limited by a fixed stop when engaged by a smooth-edged coin to wedge the coin in the coin path, the said member is provided with a straight operating face constituting a portion of one edge of the coin path and is so mounted that in its normal position and throughout its lateral displacement the face is inclined relative to the opposite edge of the coin path to produce the said wedging action to arrest smooth coins. The movable member 6, mounted by the pin-and-slot 4, 5, is of right-angled triangular shape and is formed with an operating face 9 and a projection 7, normally resting against a fixed pin 8. A milled coin, by its milled edge engaging the knife-edge 11, rotates the member 6 about the pin 4 and passes on. A smooth coin fails to rotate the member 6, which is, however, displaced by sliding on the pin 4 along the slot 5 until its side 14 abuts against the pin 8, any pivotal movement being prevented by a fixed pin 12. The smooth coin is thereby wedged between the face 9 and the opposite edge of the coin path until the movable side of the coin shoot is opened to discharge it.
