Title: Improvements in or relating to the production of pictures with stereoscopic or relief effect
IPC: G03B35/24
Filed: 1932-11-18
Abstract: 410,515. Stereoscopic photography. ZAFIROPULO, J., 51, Rue de Passy, Paris. Nov. 18, 1932, No. 32687. [Classes 97 (i) and 98 (ii).] Relates to the production of single photographs exhibiting stereoscopic or relief effects. The system employed is the same as that described in Specification 410,517, consisting of an objective A, Fig. 1, having a diameter approximately equal to the normal human eye separation (about 63 mm.) and an aperture ratio of at least f /4 and preferably f /2.5, in conjunction with a film or plate the sensitive surface C of which is covered by a grating B of spherical or cylindrical lenses having their foci in the sensitive surface, and having an aperture ratio equal to that of the objective. According to this invention the effective diameter of the objective is brought to the desired value by supplementary means, thus enabling an objective with an actual diameter of less than 63 mm. to be used. In Fig. 7, the supplementary means comprises a pair of mirrors S, S<1> mounted behind the objective and rotating around the optical axis. The rotating mirrors may be replaced by two stationary reflectors, the inner one being conical and the outer one frusto-conical, or by a number of pairs of stationary plane mirrors S, S<1>, Fig. 8, or by a number of rhombic reflecting prisms. The increase in the effective diameter may also be obtained by placing in front of the objective an afocal lens system comprising a positive lens G, Fig. 16, having a diameter of 63 mm. and a negative lens H of such size that it touches the conical surface having as its base the lens G and as its apex the common focus O of the lenses G, H. If a diaphragm is used to stop down the objective it must be of such form that it reduces the diameter of the objective in one direction only, e.g. a horizontal slot extending across the entire width of the lens could be used. The relief effect may be enhanced by using an objective having an effective diameter of 126 mm. and an aperture ratio of f /1.25 in combination with an unsymmetrical diaphragm, the opening of which is on one side only of the axis of the objective. The negative films or plates may be developed by reversal to form positives for direct viewing, the lenticulated side being held nearest the eye. Alternatively the plain surface of the positive may be coated with a reflecting layer so that the picture is seen by reflection. In projecting pictures obtained as above described on to a screen, the effective diameter of the projection objective A, Fig. 18, is brought to such a value b by supplementary means such as reflectors Z, S, that the ratio of the distance b to the distance a from the projector to the screen Q is equal to the aperture ratio of the taking objective. Forms of screen surfaces which may be used to impart relief effects to the projected pictures are described in Specification 410,518.

Title: Engine starters
IPC: F02N99/00
Filed: 1931-11-27
Abstract: 384,780. Starting ; turning gear. ARMSTRONG SIDDELEY MOTORS, Ltd., VIALE, S. M., and THOMAS, A., Armstrong Siddeley Works, Park Side, Coventry. Nov. 27, 1931, No. 32906. [Class 7 (v).] A spark-ignited aeroplane or other engine is started by priming it, turning it by electric means at a speed of 3 to 5 revolutions per minute, so that self-actuation will not occur, and igniting the charge, when fully compressed, by means of an independent spark-generator, which may comprise a trembler coil or a handoperated magneto. Priming is preferably effected by means of a hand pump, injecting fuel into each of the induction pipes in the case of a radial engine. The operation of a switch 61, Fig. 8, first connects the primary winding of a trembler coil 57 to the battery and then switches on the starting motor 5. The shaft 2 of the starter is driven from the motor 5, Fig. 1, through planetary gearing comprising compound planet pinions 7, the gears of which have one tooth difference and mesh with a stationary annulus 8 and a driven annulus 9. A worm 12 on the shaft 2 drives a worm wheel 13 mounted on a hollow shaft 11 on which is splined a dog clutch member 48, Fig. 2, movable automatically into engagement with clutch dogs 47 on an engine shaft 46. The member 48 is formed externally with a roughened surface or with inclined grooves 55, Fig. 4, engaged by spring plungers 56, and is formed at its inner end with cam faces 51 engaging corresponding faces on a non-rotating sleeve 52, in order to effect the axial clutching movement. The starter shaft 2 may be actuated manually by a cranking handle applied to the end 4, the motor 5 then being automatically disconnected by the movement of a cone clutch member 24 having a threaded connection with the shaft 2 and engaging a clutch surface in the annulus 9. To prevent the shaft 2 being turned by a backfire of the engine, a ratchet wheel 14 on the shaft 2 is engaged by spring-pressed pawls 15, and the worm wheel 13 is mounted on the shaft 11 by means of a series of conical rings 29, to which axial pressure is applied by a nut 31. Adjustment of the nut may be effected by a worm engaging an external screw thread or helical teeth on the nut, or splines on the collar may be held by a sliding collar while the worm gearing 12, 13 is manually turned. In modifications, (1) backward rotation of the shaft 2 is prevented by a coned nut threaded thereon and biased by a coil spring into light frictional contact with a coned surface on the stationary casing ; and (2) an additional planetary gearing is interposed between the motor 5 and the shaft 2, and the hollow shaft 11 surrounds a supplementary shaft through which auxiliary devices are driven from the engine shaft.

Filed: 1971-07-15
Abstract: 1345440 Rescuing device for cableways OBRDA 15 July 1971 [20 July 1970] 33319/71 Heading B7L [Also in Division A3] A device 2 for rescuing persons from the chairs of an overhead cableway comprises a J- shaped supporting member 6 having mounted thereon rollers 8 for movement of the device along a cable 1, frictional braking means in the form of a braking plate 12 which in a first position is biased by a spring 13 and lever and cam arrangement 16, 15 to contact the cable and in a second position is spaced away from the cable, a cylinder 23 which by means of a free-wheeling bearing can rotate in one direction only and which cylinder has wound around it at least one and a half times a rope 4 to one end of which is releasably connected a body harness (not shown) and means for transporting a rescuing person so that he can operate the braking means, said transporting means comprising an essentially vertically extending first bar 3 which carries a plurality of horizontally extending bars 20. The device also includes a locking plate 10 having a lock 12<SP>1</SP> which engages an annular groove provided in a member 11 about which the lever 16 pivots so that once the device 2 is in position on the cable 1 it cannot be accidentally dislodged. In a rescue operation the device is mounted on the cable 1 with the braking means in the first position to prevent movement of the device. A first person mounts the device by stepping on the transporting means 3, 20 and releases the braking means using the lever 16 thus allowing the device to travel down the cable 1 to the position where a second person is to be rescued, the braking means again being applied at this point to arrest the motion of the device. The first person then fastens the harness (not shown) around the person to be rescued and attaches the harness to the end of the rope 4 which when acting on the cylinder 23 will not cause the cylinder to rotate. The other end of the rope 4 is then pulled slightly to lift the second person free of the chair in which he may be seated and then slowly released causing the rope 4 to slip  around the cylinder 23 and thus lower the second person to the ground. The first person, standing on the chair from which the second person has just been rescued, then releases the lever 16, opens the locking plate 10 and transfers the device to a position in the cable 1 downstream of the chair and is ready to repeat the procedure for rescuing the next person. In order to withstand the heat generated in the procedure the cylinder is made of a heat conductive material, preferably an aluminium alloy, and the rope 4 is made of a polyamide material.

Title: Floatless carburettor
IPC: F02M19/035
Filed: 1928-11-14
Abstract: 326,526. Kreher, M. Nov. 14, 1928. Spray carburettors.-The fuel supply to a floatless carburettor formed in two parts connected together by screwing is controlled by a needle valve supported by a suction-actuated member 21 connected thereto by a three-arm blade spring 27. Normally, the member 21 remains out of contact with a step 28 formed on a partspherical element 15 having radial fuel orifices 15a which communicate with a well 16 leading through passages 19 to a supply duct 9. In the event of back firing, the member 21 seats on the step 28. To moisten the charges, water is supplied through a passage 10 to a wick 31 housed in an annular chamber formed in a ring 29, the chamber discharging into the carburettor through orifices 32. In the modified construction shown in Fig. 8, the needle valve is supported by a sliding sleeve 34 between which and a collar on the valve is inserted a blade spring 33. The sleeve is forced on to the step 28 in the event of back-firing. In a further modification, the suction-actuated fuel valve is dispensed with; a fuel control valve mounted in the supply passage 9 is controlled by the movements of an actuating arm on the throttle valve 6. According to the construction shown in Fig. 14, the fuel supply is controlled by a spring- presesd valve 50 mounted in a hand-controlled sliding valve 47 having a longitudinal passage 51 which places the supply duct 9 in communication with a passage delivering into the well 16 when the engine is running at full load. At starting, and when running at low loads, the valve 50 is moved from its seat by the pressure difference in the passages 47a and 48. In the construction shown in Fig. 15, a short suctionactuated valve 52 controls the fuel supply to the well 16.
