Title: Improvements in and relating to photographic cameras
IPC: G03B7/00
Filed: 1954-11-11
Abstract: 763,154. Photographic cameras. DECKEL, H., and DECKEL, F. W. Nov. 11, 1954 [Nov. 13, 1953; Sept. 20, 1954] , No. 32696/54. Class 98(1) A photographic camera has an adjustable coupling between the shutter speed adjusting member and the diaphragm adjusting member and the latter member is made to operate a depth of field indicator comprising two wire indicators reading in conjunction 'with the focusing scale. Fig. 2 shows the rear view of the shutter, which comprises a diaphragm adjusting ring 26 having teeth 40 on the upper edge which teeth operate a pinion 42 and cam 44. A resilient wire 46 is fixed to the shutter and the ends 50, 52 press against cam 44 and indicate against the scale on the focusing ring (not shown). Adjustment of the aperture thus results in movement of wires 50, 52 to indicate the appropriate depth of field, which will depend on the position of the focusing ring. The shutter speed setting ring 18 has notches 36 round its lower edge. These notches co-operate with a pin 32 on a resilient arm 27 of the diaphragm adjusting ring 26. Thus the relative positions of rings 18 and 26 can be set to an exposure value scale on the front of ring 18 (not shown) depending on the light conditions, and then movement of ring 18 produces corresponding movement of ring 26 so that light entering the camera remains constant. This mechanism is the same as described in Specification 744,962. Specification 275,462 [Class 98(i)] also is referred to.

Title: Process for the production of pure arsenious oxide from arsenical products, such as crude arsenical flue dust, containing arsenic in the form of arsenious oxide
IPC: C01G28/00
Filed: 1930-11-03
Abstract: Materials such as crude arsenical flue dust containing antimony and also metallic or other constituents not volatile at the sublimation temperature of the arsenious acid present are extracted at elevated temperatures, for instance under pressure at 150 DEG  C., with water, dilute sulphuric acid, or weak solutions of alkalies, and the solutions cooled after concentration if necessary to deposit pure arsenious oxide.  Deposition of the oxide may be assisted by addition of considerable quantities of solid arsenious oxide, preferably in a finely divided form, which is stirred into the solution.  If soluble organic materials are present, the solution may be decolourized, preferably prior to filtration of undissolved residue, as by addition of active carbon.

Title: Improvements in and relating to photographic flashlight devices
IPC: G03B15/04
Filed: 1966-07-22
Abstract: 1,103,682. Flashbulbs; flash guns. AGFAGEVAERT A.G. July 22, 1966 [July 30, 1965], No. 33095/66. Headings G2A and G2C. In a photographic flashlight device having a plurality of flash bulbs to be flashed off successively, one main electric lead 16, Fig. 1, for the ignition of the bulbs is connected to one lead 11 of each bulb and the other main lead 17 to the second lead 12 of the first bulb, a contact element 13 and lead 18 being provided between each bulb and the lead 12 of the bulb next to be flashed off so that as each bulb is flashed off its circuit is broken at the filament 10 and connection is made between the lead 17 and the lead 12 of the next bulb in the series via the contact 13 of the preceding bulb and the lead 18. The bulbs 6--9 may be mounted in a common holder 1 provided with recesses 2... 5 which may be made reflective by metallizing and dimpling, the front of the holder being closed by a pane of transparent material. The holder may be provided with a foot to fit a conventional camera socket, the foot being long enough to extend beyond the top of an extending reflector fitted to the camera. The electrical connections may be in the form of a printed circuit. Contact between the appropriate leads on flashing may be effected by applying to the top of the contact lead 40, Fig. 6, a bead of conducting fusible material 41, which may be enclosed in a ceramic cup 39. The lead 37 to the filament 36 is external to the cup and the second lead 38 passes through it. Melting of the material 41 by the heat of combustion connects the leads 38 and 40. In a modification, one main lead is flexible and is held away from the contact lead by the tension of the filament, release of which makes contact between the two leads. In another form, one main lead passes through a chamber containing a globule of mercury and closed at the bottom by a puncturable membrane, the pointed end of the contact lead touching the underside of this. Expansion of the mercury due to the heat of combustion causes puncturing of the membrane, closing the circuit between the main and contact leads.

Title: Improvements in or relating to high frequency variable inductors
Inventor: MIFFLIN LEO V
IPC: H01F21/06
Filed: 1953-12-02
Abstract: 740,600. Inductors. COLLINS RADIO CO, Dec. 2, 1953, No. 33505/53. Class 38 (2). A variable inductor comprises a coil and a movable core, movement of the core longitudinally of the coil being non-linear in relation to the rotation of a shaft causing the core movement. Rotation of a shaft 14 causes a cam follower mechanism 23 to travel longitudinally along a coil 10, a magnetic core 12 being attached to the mechanism 23 to move therewith, thus varying the inductance of the coil 10. The movement of the core 12 is, however, made non-linear with respect to the rotation of the shaft 14 by provision of a series of thin washers 26 each of which has an internal projection 24 thereon. As the cam follower mechanism 23 moves longitudinally when the shaft rotates rollers 38, 39, which form part of the cam follower mechanism, follow the projections 24 (see Fig. 2). The washers 26 are capable of angular movement relative to one . another so that the track formed by the projections 24 may assume a serpentine shape. When the desired shape has been attached the washers are clamped together to prevent further relative movement. Thus as the shaft 14 is rotated the core 12 will move through the coil 10 to produce any desired characteristic of coil inductance versus shaft rotation. U.S.A. Specification 2,468,071 is referred to.

Title: Improvements in and relating to undercarriages for aircraft, especially helicopters
IPC: B64C25/62
Filed: 1946-11-12
Abstract: 618,914. Launching aircraft. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and WATSON, K. Nov. 12, 1946, No. 33581., [Class 4] An aircraft undercarriage, especially for helicopters, comprises a landing wheel associated with two independent shock-absorbing mechanisms operative in series, one being capable of dissipating the energy of an emergency landing without imposing a deceleration exceeding 3g and the other being capable of dissipating the energy of normal landings and taxying shocks. The landing wheel 18 is carried in a fork 17 secured to the plunger 16 which together with the cylinder 15 forms a resilient shock-damping buffer capable of dissipating normal landing shocks. Vertical movement of the plunger 16 in the cylinder 15 takes place in the plane of rotation of the wheel 18 and thus gives rise to no scrubbing action on the tyre. When a certain critical loading is exceeded, the cooperating faces 48, 49 ensure that the wheel 18 turns into the plane containing the arm 9 of the emergency landing system. The arm 9 is pivoted at 8 to the aircraft and is provided with a hydraulic buffer 11 to control its pivoting action. The buffer 11, Fig. 2, comprises a cylinder 19 which houses a plunger 20 having an internal bore 21 and a restricted orifice 22 at the lower end. The return of the oil in the cylinder 19 to the reservoir 26 via pipes 23, 25 is controlled by a spring-loaded valve 32, the setting of which determines the critical loading under which the emergency landing system 9, 11 begins to collapse. A hand-operated lever 35 enables the buffer 11 to be collapsed at will when the aircraft is on the ground. To enable the emergency landing system to be fully extended again when the aircraft is airborne, a pump 28 is provided to pump the fluid back into the cylinder 19, a non-return valve 29 being provided in the delivery pipe 24 to prevent back-flow of fluid from the buffer 11 to the reservoir when the buffer is under load and the pump not working. An overload relief valve 31 is provided and means may be provided to hold this valve open when the landing system is under load and thus prevent the pump tending to jack the aircraft up whenever the pump is running. Other arrangements for providing an emergency landing system are also described.
