Title: Improvements in or relating to photography
IPC: G03B17/52
Filed: 1947-01-29
Abstract: 684,591. Photographic daylight processing apparatus and cameras incorporating such. STEVENS, A. H. (International Polaroid Corporation). Jan. -29, 1947, No. 2760/47. Classes 98 (i) and 98 (ii). A housing contains means for mounting a supply of sheet material carrying thereon a container of processing agent, means for guiding a film and this sheet material, and a pair of pressure applying elements such as rollers for bringing the film and sheet material into face to face relationship and compressing them whereby processing agent may be released from the container and spread between the film and sheet material to effect processing as in the manner indicated in Specification 684,592. In modifications the sheet material does not carry a container, and a separate container having a valve and spout for feeding processing agent between the film and sheet material is provided; alternatively one or more separate containers may be present in the housing together with means for feeding one of them between the film and sheet material for release of the processing agent by the pressure elements. The processing apparatus consisting of this housing and its contents may be embodied in a camera, or may serve as an attachment interchangeable with a standard camera back; and may be used for direct production of positive prints on the sheet material by transfer and reduction of unexposed portions of light-sensitive material on the film in the manner described also in Specification 684,592. Figs. 1 and 2 show a camera whith fim supply means 17 from which the film 44 passes upwards into exposure position behind lens 15 and after exposure meets sheet material 27 carrying container 28 supplied from spool 24; the film and sheet material are pressed together by pressure rollers 30, 31 rotated by hand-crank 35 to release processing agent from the container and then pass downwards to rest while processing is effected, after which the treated portions may be withdrawn from the housing consisting of hinged portions 11, 20, 40 and severed from the remainders of their lengths. Figs. 6 and 7 indicate the modifications; in Fig. 6 processing agent is supplied from container 142 via spout 144 to the film 132 and sheet material 138 in the nip of pressure rollers 136; and in Fig. 7 a container 94a, 94b is dispensed, also into the nip of the pressure rollers, from magazine 90.

IPC: E21B7/04
Filed: 1916-02-24
Abstract: 100,130. Kaempfe, H. Anschutz-. Feb. 27, 1915, [Convention date]. Bore-hole clinometers.-A tool for sinking vertical bore-holes comprises a hollow bar containing a pendulum device by which deviations from the vertical are indicated at the surface, and carrying a boring-bit with a non-symmetrical cutting edge, for instance with an inclined cutting edge, by which the direction of the bore-hole can be controlled. The pendulum device may be such as is described in Specification 27005/12 and is preferably adapted to slide against the resistance of springs or rubber pads to reduce jarring. Two independent pendulums mav be provided, each measuring one component of the deviation. When a deviation is indicated, the blows of the boring tool are controlled so as to cut the bore-hole deeper at one side, the bit then tending to slip towards that side and correct the deviation.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M17/14
Filed: 1921-01-21
Abstract: 158,553. Pallas-Zenith Ges. Jan. 22, 1920, [Convention date]. Spray carburettors.- A mixture of constant composition is obtained by providing a suctionactuated regulating device a, for example an air float or valve, in the Venturi-shaped portion b of the induction pipe and supplying the fuel through two pipes c, d, the pipe c opening into a part of the induction pipe where the air passage is controlled by the regulating-device so that the air speed is constant, and the pipe d delivering into a part where the air speed varies with the speed of the engine. The pipes c, d are provided with air inlets g, h, and they may deliver at the same or opposite sides of the induction pipe. The inlets to the pipes c, d and the inlets g, h may be formed as constricted openings. The device may be adapted for different engines by varying the load on the regulating-device or the cross-sectional area of the air passage. Accordirg to the Specification as open to inspection under Sect. 91 (3) (a) the regulating- device may be loaded by a spring or by fluid pressure, and the induction pipe may be movable instead of the regulating-device. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to devices for filling liquids into containers
IPC: B67D7/48
Filed: 1955-02-01
Abstract: 770,706. Filling tanks. BEUL, M. L. Feb. 1, 1955 [Feb. 2, 1954], No. 2930/55. Class 21 [Also in Group XXIX] A liquid supply mechanism of the type that automatically closes when the receiving vessel is filled, comprises a spring actuated valve 3, Fig. 1, for normally preventing flow, means 14 for opening the valve 3, an air chamber 18 closed by a diaphragm 17 linked with the valve 3, a main tube 23 linking the air chamber 18 with the outside air at a point 24 near the outlet of the device, and a branch tube 23 extending in the direction of liquid flow, the branch tube being surrounded by a sleeve 32 that can be displaced against a spring 34 by the liquid flow to increase the cross sectional area of the flow path. A handle 14, enables a lever 8 to be rotated about a pivot 9 and open the valve 3 against a spring 5. In operation, the vacuum created in the tube 21 by the flow of liquid draws air through the orifice 24 until this orifice is covered by the liquid in the tank being filled. The vacuum in the tube 21 then raises the diaphragm 18, and cam 16 on the diaphragm permits the pivot 9 to move to the left in a slot (not shown). The spring 5 then closes the valve 3. To prevent liquid entering the orifice 24, a float valve 28 may be arranged as in Fig. 5 to close the opening 29 when liquid enters the opening 27. One or more abutments 25 are used to accurately position the device with respect to the tank 30 to be filled.
