Title: Stops for preventing the opening of doors
IPC: E05C3/04
Filed: 1974-03-22
Abstract: 1421711 Door stop devices L A MCLENNAN 22 March 1974 [26 March 1973] 12902/ 74 Heading E2A An abutment stop mechanism for blocking opening movement of a closure 1 swingable about an upright axis comprises a stop member 14, a mount 5 adapted for mounting adjacent to but independently of the closure in closed position and supporting said stop member for turning about an upright stop member turning axis, substantially parallel to the closure axis of swing, between a closure-blocking position of the stop member obstructing a predetermined opening-movement path of a stop-engageable portion of the closure and a closure-clearing position of the stop member out of the opening-movement path of the closure, in which closure-blocking position of said stop member a closure-engageable portion of said stop member spaced from such upright stop member turing axis is engageable by such stop-engageable portion of the closure to limit its movement along such predetermined-opening-movement path. The mount is located so that a line joining the stop member turning axis and the closure-engageable portion of the stop member in closure-blocking position is at an angle a of less than 45‹ to such predetermined opening-movement path of the stop-engageable portion of the closure, and there are latch means engageable between said mount and the stop member for preventing swinging of the stop member out of closure-blocking position relative to the mount. As shown, the stop member 14 and a keeper 18 are pivoted on a pintle 13 mounted in bosses 11, 12 of ears 9, 10 of the mount 5 and in the closure clearing position are biassed upwardly, as seen in Fig. 2, by a spring 23, the stop member and keeper having co-acting cam surfaces 32, 32'. When the stop member 14 and keeper are swung conjointly into the closure-blocking position when the door is closed and while the stop member is held manually in the swung position, Fig. 5, the wedging co-action of the cam surfaces causes spreading apart of the stop member and keeper resulting in movement of the stop member towards the boss 12 whereby the groove 17 in the stop member is pressed over the projection 16 of the ear 10; this latching action prevents the stop member from swinging out of the closure blocking position. The crowns of the cam surfaces move past the dead centre position whereby the recesses 33, 33' are engaged to maintain the keeper in a position to hold the stop member latched. The stop member is moved to the closure-clearing position by swinging the keeper 22 whereby the stop member is shifted axially by the spring 23 to clear the projection 16. In modifications, (a) a notch is formed in the ear 9 adjacent the stop member and for the reception of the shackle of a padlock, the latter positively holding the stop mechanism in the closure-blocking position, and (b) the mount includes an aperture for reception of the latch bolt of a door lock.

Title: Casting plant for metals
IPC: B22D5/04
Filed: 1962-04-05
Abstract: 965,333. Casting-machines. F. MOELLER, and K. NEUMANN, [trading as MOELLER & NEUMANN o.H.G.]. April 5, 1962 [April 7, 1961], No. 13135/62. Heading B3F. In casting apparatus, particularly for zinc pigs, the metal is cast into stationary, open-topped moulds which rest on a conveyer for further transport after solidification, and a radiant hood or hoods is or are arranged to move over the moulds at the casting point to heat the upper surfaces of the castings during the solidification period. Pairs of mould 1,2; 3,4 and 5, 6 are filled in turn from a ladle 9, and associated radiant hoods 10, 11, 12 are moved into position over the moulds to heat the top of the castings while the ribbed bottoms of the moulds are simultaneously cooled by spraying. The hoods may be used to preheat the moulds before pouring. Pouring commences with the moulds tilted at an angle of about 30 degrees and ends with the moulds horizontal to prevent immediate hardening of the metal spreading out over the bottom of the mould. The moulds are then moved along the conveyer 7 and each, in turn is transferred by a pusher 18 to a device 19 which inverts the mould to allow the casting to fall out on to a conveyer 16 which carries it to rolling or heating &c. stations, the empty mould travelling in the opposite direction on a conveyer 17 to be returned, after cooling by sprays, to the casting station. The inverting device comprises two opposed roller platforms 29, 30. The entering mould is clamped to the platform 29 by means 36, 38, 43 and the roller platform 30 lowered by means 31 to engage the top of the casting. The device is inverted and the roller platform 30 lowered away from the mould carrying the ingot with it. The device is tilted slightly so that the ingots is gravity fed from the roller platform 30 to the conveyer 16, and then returned so that the mould may be unclamped and gravity fed to the conveyer 17. In a modification, the moulds are attached to an endless chain, the hood being arranged to travel in the direction of movement of the chain and to cover half the moulds on the upper chain run. Alternatively, the moulds may be mounted on a rotary table with a hood arranged to be turned about the centre of the table and a casting furnace travelling around the table.

Abstract: 1322992 Glass fibres for optical waveguides CORNING GLASS WORKS 5 May 1971 [11 May 1970 15 Sept 1970] 13325/71 Heading C1M Glass fibres for an optical waveguide comprise a cladding layer of pure fused silica or a doped fused silica and a core of doped fused silica, the dopant being in such amount that the index of refraction of the core has a greater value than the index of refraction of the cladding layer. Dopants suggested are of Cs or Rb when diffusion is allowable to give an increasing diameter core or one or more of the following oxides when no diffusion is required: Ti, Ta, Nb, Sn, Al, Zr, Yb and La. Amounts of the dopants preferably up to 15% by weight, but all may be up to 25% except Al 2 O 3  up to 40%, and the maximum TiO 2  20% and for ZrO 2  and Nb 2 O 5  5%. The Figure shows how the amounts may be chosen to give desired refractive indices. When the cladding layer is also doped, the same, but more, dopant may be used for the core, or a different dopant used, the amounts being chosen to give the greater refractive index for the core, and in an example, a larger amount of Al 2 O 3  to a smaller amount of TiO 2  for the core will give the required result. By suitable refractive indices for the glasses used and diameter of the core, the optical fibre can be adjusted to limit light projection to a particular mode. The glass fibres may be made by the conventional drawing down of a rod of core glass surrounded by a tube of cladding glass or the methods of Specification 1,322,993 may be used. Specifications 1,213,603 and 1,113,101 are also referred to.

Abstract: 696,577. Cylinders; cooling; combustion chambers; regulating; valve gear. LEYLAND MOTORS, Ltd., and MUELLER, A. May 30, 1951 [May 30, 1950], No. 13478/50. Classes 7 (ii), 7 (iii) and 7 (vi). In a two-stroke internal-combustion engine having piston-controlled ports, for example exhaust ports 17, and ports, such as inlet ports 12, controlled by a sleeve valve 19, the latter is reciprocated from the engine shaft 4 by mechanism, for example an auxiliary crankshaft 24, connecting rod 25, rocker 22 and link 23, which imparts to the valve 19 rapid upward and downward movements spaced apart by less than half the time of one engine revolution and causes the valve to dwell near its bottom position in the interval between a downward and an upward movement. The liner 2, which is arranged in the cylinder casting 1 so that the inner portion is " dry " and the outer part " wet," incorporates the inlet ports 12 that are directed at a large angle to the cylinder radii and tangentially to a circle of less diameter than the cylinder in order to impart a whirling to the incoming super-charged air supplied through pipes 10 and openings 11 in the casting 1 which lead to ports 12; cooling fins 13 are provided on the casting 1 in the vicinity of the ports 12. The outer end of the cylinder is closed by a junk head 15 projecting into the cylinder as far as the ports 12, an injection nozzle 16 being located in the head 15 and spraying fuel into a combustion chamber 7 in the piston head. The valve 19 has a clearance with the piston 6 and a close fit with an enlarged part 13 of the liner. Piston rings 20 are arranged on the head 15 in order to provide a seal between the head 15 and valve 19. The shaft 24 is driven from the engine shaft 4 through bevel gearing whilst the rocker 22 is pivoted upon an eccentric 31 driven by gearing at twice the speed of shaft 24; the two arms of the rocker 22 are of approximately equal length and the throw of eccentric 31 is about onethird of the throw of shaft 24 which together with the obliquity of the shaft connecting rod 25 ensure that valve 19 has an abrupt lift and drop in addition to the dwell period. The sleeve valve motion is comprised partly of a reciprocation of less amplitude at double the rate. An example of valve opening and closing times is given.
