Title: Improvements in pattern reversing mechanism for knitting machines
IPC: D04B15/66
Filed: 1941-03-14
Abstract: 540,524. Knitting. SCOTT AND WILLIAMS, Inc. March 14, 1941, No 3539. Convention date, March 16. 1940. [Class 74 (ii)] Relates to means for reversing the drive of a pattern-mechanism, as and when required. The invention is described in connection with a dial knitting-machine in which the needle selection for pattern effects is secured by the scanning of a pattern by electrical devices. The direction of movement of the scanner is controlled by a clutch, which is reversed periodically under control of pattern mechanism or otherwise. The knitting-machine comprises a frame A in which the needle cylinder 17. pattern cylinder 65, and the support for the fabric take-up mechanism rotate in synchronism. The frame A also carries rods 10 on which reciprocate crossheads 11 carrying two scanning devices 12 driven up and down the rods 10 by screwed shafts 14. The pattern cylinder 65 is mounted on a gear 68 which drives, through a gear train 22, the shafts 14. The gear train 22 includes spaced bevel gears 73, 74 freely rotatable in a shaft 14 and caused to rotate in opposite directions by an intermediate gear 75. A clutch 76 is slidably keyed to the shaft 14 between the gears 73 and 74. The arrangement is such that the clutch cannot be disengaged from one gear 74 until it has engaged the other gear 73. The clutchshifting fork 24 is connected to a rocking rod 28 on the other end of which is mounted a lever 34. Either end of the lever can be pulled down by a rod such as 35 connected to pattern-controlled levers 38, 39. The pattern-chain 47 is fed on by a ratchet actuated by a cam 59 on the take-up mechanism support. In a modification the pattern control is dispensed with and each crosshead is automatically reversed at the end of its traverse. Specification 505,000 is referred to.

Title: Improvements in or relating to the production of tyres
IPC: D06F55/02
Filed: 1958-11-07
Abstract: 904,595. Tyre moulding presses. BRIDGE & CO. Ltd., DAVID. Nov. 7, 1958 [Nov. 7, 1957], No. 35771/58. Class 87(2). A tyre press for making or retreading tyres in which the tyres are cured by applying a curing medium directly to the inside of the tyre, comprises collapsible bead shaping and clamping rings 9, 10 having alternate long and short segments 21, 20 provided with yieldable members 51 which force the beads against the corresponding toe rings 11, 12, Various modified forms of the members 51 are shown in Figs. 12-15 not shown. These modifications include rubber and metal diaphragms which are extended by curing medium under pressure. In operation a pulley band carcass T is inserted between the mould sections 6, 8 and the top mould section 8 is moved down to form the carcass into tyre shape . Fluid pressure may be supplied to assist this inital shaping. At this stage the rings 9, 10 are extended to clamp and shape the beads by actuating piston rods 40. Curing medium is fed through tangential passages 80 in the rings which causes the medium to swirl through the tyre. Condensate may be removed from the tyre through a tube 75 connected through a hose 76 to the atmosphere or to suction. Alternatively it may be removed by compressed air. After curing, the top mould section 8 is raised and as this section has been treated with a release agent it is parted from the tyre, the bottom ring is then raised to strip the tyre from the bottom mould section. The ring 9 is then collapsed and withdrawn from the tyre and the finished tyre is lifted by the top ring 10, a conveyer is placed beneath the tyre, and the top ring collapsed to allow it to fall on to the conveyer. If the tyres have nylon cords, before finally removing the tyre from the mould, cold water may be circulated through the tyre whilst the tyre is inflated to stress the cords while cooling. If the press is used for retreading ordinary tyres a rubber sealant may be supplied through the passages 80 or through special nozzles on the top ring 10 to seal the walls of the tyre. The toe rings 11, 12 are provided with two tapered parts 70, 71, grooves 73 and vents 72 to allow air to escape. An arm 107 on the piston rod 40 actuates a switch 106 to ensure that the ring can be moved down only when it is in an extended position. The moulds may be heated by circulating steam or hot water through platens 5, 7.

Title: Improvements in or relating to valve actuating mechanisms for internal combustion engines
IPC: G05G7/12
Filed: 1948-02-06
Abstract: 649,192. Shaft couplings. EARL, C. C. Feb. 6, 1948, No. 3574. [Class 80(ii)] [Also in Group XXVII] A valve-actuating cam A is driven with cyclically varying angular velocity through a pin and slot connector, or a link, by a rotating driving member B on a shaft S which is parallel to the cam shaft but is shiftable along the line X-Y, or arc X'-Y', to vary the period of opening of' the valve. The shaft S is in line with the cam shaft at high engine speeds, the angular velocity of the cam being then constant. At lower speeds the shaft S is lowered relative to the cam shaft, preferably by a speed responsive governor acting through a servomotor. The angular velocity of the cam will then vary during each revolution, being greater than that of the member B, when the nose is upwards and acting on the tappet F, and less than that of the member B when it is downwards. Thus the valve opening period (in crankshaft degrees) is reduced. The member B is preferably mounted on a pivoted arm. As shown in Fig. 4, two driving members B, B<SP>1</SP> are driven by a common pinion G and carried by arms C, C' pivoted at E and connected by links H, H<SP>1</SP> to a sliding block V adjusted according to speed to adjust the position of the driving members B, B<SP>1</SP> relative to their cam shafts. In a modification the links H, H<SP>1</SP> are connected to an angularly adjustable pivoted arm. In a further modification the links H H' are omitted and the arms C, C' are pivoted on the axes of idler gears introduced between the gear G and the members B, B<SP>1</SP>, the ends of the arms C, C' being arc-shaped and provided with intermeshing teeth or connecting straps for simultaneous adjustment.

Abstract: 745,915. Hydro-pneumatic shock-absorbers. BRITISH MESSIER, Ltd. May 7, 1954 [Feb. 9, 1953], No. 3617/53. Class 108 (3). [Also in Group XXXIII] A shock-absorbing unit for a helicopter undercarriage comprises a cylinder 20 closed at its upper end and secured by a ball connection 21 to the undercarriage leg 11. A tubular plunger 23, connected by a pivot 24 with a wheel-carrying arm 13, is slidably mounted within the cylinder 20 to which it is sealed by an external piston 25 formed with damping apertures 26, a number of which are sealed by a plate valve 27 upon downward movement of the plunger 23 under the action of a spring 29. A separator piston 30, having an upwardly extending trunk-shaped portion, divides the interior of the plunger into two parts and the cavity 31 formed in the plunger 23 below the piston 30 constitutes an air chamber. The cavity above the piston 30 and the interior of the cylinder 20 is completely filled with oil. A fixed damping piston 33, formed around its periphery with apertures 40, is located within the trunk-shaped extension of the piston 30 and is secured to the cylinder 20 by a tube 34 which encloses a piston 36 loaded by a spring 38. The damping piston 33 is formed with apertures 41, 42 some of which are closed by a plate valve 43 backed up by a spring 44. In operation air chamber 31 is inflated to give sufficient pressure to the oil in cylinder 20 to support the aircraft. If slow movements of the shock absorber take place these are not materially damped by the passages 40 but are damped by the orifices 41 over a pressure range depending on the rate of the spring 44, the displaced oil passing into the space below the piston 36 against the action of spring 38, air above piston 36 being vented to atmosphere through an aperture 35. Under rapid compression of the shock absorber, such as occurs when landing, the pressure above piston 30 exceeds the flow pressure of valve 43 and the resulting increase of oil pressure above the piston 30 causes said piston to be displaced downwardly against the air pressure in the chamber 31. During this phase damping is produced also by the apertures 26 in the piston 25.

Title: Improvements relating to the admission of air to the induction pipes of internal-combustion engines
IPC: F02D9/00
Filed: 1933-02-10
Abstract: 396,639. Auxiliary - air admission. ERICSSON, A., Hovik, near Oslo, Norway. Feb. 10, 1933, No. 4199. Convention date, Feb. 20, 1932. [Class 7 (ii).] The formation of a vacuum in the cylinders during over-run is prevented by an electricallycontrolled auxiliary-air valve 8, operated by suction in the induction pipe 4 through a locking plunger 14, which is lifted to bring an armature 24, connected to a valve 20, within the influence of a magnet 25, suction being then admitted to a passage 19 to lift the valve 8. The plunger 14 is mounted on a flexible diaphragm 27 and suction is conveyed to the magnet chamber 26 by a pipe 28. When no suction exists in the induction pipe, the chamber behind the valve 8 is vented to atmosphere by a groove 17 and ports in a chamber 12. When the plunger 14 lifts against springs 38, 39, this connection is cut off. The valve 8, which, as shown, slides in a casing 16, but may be mounted on a flexible diaphragm, seats by an annular rib 9 on a packing 10 and is lifted by suction owing to the difference in area above and below the face. The valve will also open to relieve excessive pressure in the induction pipe due to back-firing. The current to energize the magnet is supplied by the generator 35 of the motor vehicle when contacts 36, 37 are closed by a speed governor and contacts 31, 32 by the throttle valve 2 being other than substantially closed. Fig. 5 shows an alternative arrangement in which the speed governor is replaced by an electric relay which closes and opens at the same current intensity by an armature 43 and a magnet having strong and weak coils 44, 45. To close the relay, current from the generator 35 passes through both coils 44, 45 and in parallel therefrom through armature 47, contacts 46, 51, lead 50, and a coil 48, and to earth via the throttle-controlled contacts 31, 32. The armature 47 is thus attracted and contacts 46, 51 opened. The weak coil 45 is alone left in the circuit and the coils 44, 45 are so sized, and the tension of a spring 64 and the air gap between the armature and magnet 43 and 63 so adjusted, that the contacts 36, 37 open at the same current intensity as that at which they close. The contacts 31, 32 are controlled by a cam 61 connected to the throttle lever by a link 62. In an alternative arrangement the armature 47 and the coil 48 are omitted, and the armature carries, on its upper side, the contact 46.
