Title: Photographic camera
IPC: G03B19/12
Filed: 1971-04-19
Abstract: 1317411 Photographic cameras COMPUR-WERK GmbH 19 April 1971 [9 April 1970] 23825/71 Heading G2A A photographic camera has a focal plane shutter and an exchangeable objective shutter, a selector switch enabling selection of one of the two shutters for exposure, and an electronic arrangement which controls the exposure when either shutter is selected, wherein both shutters complete their individual operating cycles irrespective of which shutter is selected, and the electronic arrangement is so adjustable by the selector switch that the shutter performing the exposure only begins to open when the other shutter is fully open and commences to close when the other shutter is still open. The focal plane shutter, Fig. 7, is formed by opening slides 30, 32 and closing slides 34, 36 which are fixed to respective mounting pieces 130, 132, 134, 136. The mounting pieces slide in a vertical direction on guide rods 38, 40, and are urged in a downwards direction by springs 230, 232, 234, 236. Electromagnets 470, 472, Fig.3, control the operation of the shutter. The exchangeable objective 500, Fig.2 has a diaphragm blade mechanism which runs down to a preset value upon camera operation, and a shutter mechanism which is opened and closed by a reciprocating drive ring the movement of which is controlled by electromagnets 540, 548, Fig.14a. The objective has electrical contacts K 2  which upon mounting the objective on the camera engage contacts K 1  provided on the camera. The electronic control arrangement, Figs.14a, 14b, is formed of four switching stages A1, A2, A3, A4 each having an RC timing network and a Schmitt trigger for controlling one of the electromagnets 470, 472, 540, 548. Stages A1, A4 respectively control the opening and closing operation of that shutter not selected for controlling the exposure time, whilst the opening and closing operations of the shutter selected to control the exposure time are controlled by stages A2, A3. Changeover switches 672, 674, 676, 678, conjointly operated by an external control knob, connect the stages to the respective electromagnets. The switching of the first stage to open one shutter also renders a transistor 610 non conductive, so that charging of the timing capacitor 638 in the second stage commences. The resistor 654 in this timing circuit may be set to one of two values, one giving a delay of 15 seconds for self portraiture. The RC network of stage A3 determines the exposure time, a manually variable resistor 656 or 658 being provided for each shutter. The resistors may be replaced by photo-resistors. The invention is described in relation to a single lens reflex camera, in which the lens shutter is normally open and the diaphragm is at full aperture. Upon camera operation, the shutter is closed, the diaphragm is set and the mirror moves up. If an inter-changeable lens without a shutter is mounted, the electronic control arrangement is set so that the focal plane shutter controls the exposure.

Title: An apparatus for producing articles from dissolved plastic substances by immersion
IPC: B29C41/14
Filed: 1938-08-16
Abstract: 518,226. Moulding by dipping. BRATRING, K, and INTERNATIONAL CONTAINERS, Ltd. Aug. 16, 1938, No. 24105. [Class 87 (ii)] In apparatus for making articles from dissolved plastic material into which cores.are dipped, core supports are traversed in a planetary path for successive dipping and subsequent drying, and the driving-gear for rotating the supports has means for disconnecting the drive for the dipping period of a support while the other supports continue to rotate about their axes. As shown, each rotary support carries a pair of diametrically opposed core-carrying frames 8, and the support, after the dipping of the cores of one frame, is turned to dip those of the opposite frame. The core supports are rotatably mounted on a rotatable member 4 co-axial with a sun-wheel 12 gearing with. a planet-wheel 11 for each core support. A releasable clutch 29 is provided so that the member 4 can be driven with the sun-wheel for traversing the core supports. When an immer- .sion frame 8 is at its lowest point above the bath 21 the member 4 is held stationary by a band brake or by the engagement of a pawl 19 with a hand-wheel 20. Manual application of pressure to a plunger 25 is then used to displace a rod 23 into engagement with a pin member which extends into a guide-slot 24 in shaft 6 of the immersion frame and is fixed to a clutch part 13, so that the clutch is disengaged ; at the same time a clutch 26, 27 is engaged. At this stage the frame can be turned by a handle 28 for immersing the cores. A hydraulic device 22 is used to lift and lower the bath. To effect the drying, the apparatus is arranged in a casing in which a hot current of air moves in opposition to the general movement of the. core supports. This current may be generated by heating coils 30, 32 and a cooling coil 31. Specification 518,169 is referred to.

Title: Two-stroke-cycle internal combustion engine
IPC: F01M11/06
Filed: 1959-07-14
Abstract: 905,112. Lubricating. AMERICAN BRAKE SHOE CO. July 14, 1959 [July 16, 1958], No. 24128/59. Class 12 (3). [Also in Group XXVII] A two-stroke engine 10, Fig. 1, includes a lubrication chamber with a lubrication well 83, an oil reservoir 17, and a pair of check valves 88 and 96 interconnecting the reservoir and the well at different levels to maintain a substantially constant oil level within the well, the valve 88 having a metering orifice 86 for dispersing the oil in a spray within the chamber. Crank-shaft rotation causes a spring-loaded valve plate 27 to rotate and close the inlet port to a transfer passage 28. Continued rotation causes an upward piston movement and a reduction in pressure within the chamber 16. Oil, from the reservoir 17, is injected past the spring-loaded check valve 94 through the metering orifice 86 into the well 83 and is sprayed upwardly into the chamber 16 and a finger 85 fixed to the crank-pin further disperses the oil within the chamber. When the piston 47 approaches its T.D.C. indicated at 47A, a port 68, in the valve plate 27, allows a charge of fuel-air mixture to be drawn into chamber 16 through the conduit 59 and the separator barrier 71, of a rotary oil filter 63. Downward movement of the piston 47 increases the pressure in chamber 16 and a charge of fuel/air mixture is forced through the separator barriers 71 and 81 and transfer passages 29, 42 into the combustion chamber 53 whilst any excess of oil in the well 83 is forced out through an opening 87 and past the spring-loaded check valve 96. In a modification, Fig. 6, a check valve 188 has a hinged vane 193 which serves as a closure member for the opening 193, and a separate metering orifice 86 is included in the valve housing 192. A similar valve may replace the drain valve 96 of Fig. 1. The bearing sleeves 21, 34 may be replaced with ball or roller-bearings and gaskets may be interposed between crank-case sections 13, 14 and 15. The finger 85 provides further splash lubrication on the piston downward stroke. A labyrinth oil seal is formed by lands 100, on the rotary separator portion 66, and grooves 100 on the adjacent crank-case wall. The labyrinth seal may be formed with V, truncated V, sinusoidal or rectangular lands and grooves and axial adjustment of the gap between the lands and grooves may be provided, e.g. by shims or spacers. Specification 733,743 is referred to.
