Abstract: 435,929. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Feb. 27, 1934, No. 6349. Convention date, Feb. 28, 1933. [Class 98 (ii)] Lenticular films, adapted for projection with a filter arranged at a desired distance from the film different from that of the taking filter from the original film, are obtained by arranging the films at an angle with the smooth side of the original in contact with the embossed side of the printing film and exposing through a stepped diaphragm occupying the same optical position as the taking filter in relation to the original film, the optical position of the diaphragm in relation to the printing film being altered to correspond with the desired position of the projection filter. As shown in Fig. 1, the original and printing films B, C, are disposed at a distance D from the diaphragm A corresponding to that of the taking filter and are bent to a cylinder having its axis in the plane of the diaphragm ; the embossings of the film B may run at right angles or parallel to the axis of the cylinder, those of the film C being at right angles thereto. In Fig. 3, the optical position of the film C in relation to the diaphragm, is altered by means of a cylindrical lens. A projection filter having also a filter of different breadth may be employed by the use of a stepped diaphragm whose apertures are spaced apart in the directions parallel respectively with the embossings of the original and printing films by distances corresponding respectively with those between the centre lines of the filter strips of the taking and projection filters. Fig. 5 shows a modification in which two diaphragms A, A<1> are employed which are situated at distances corresponding to those of the taking and projection filters, and which are furnished with correlated openings spaced to correspond with the taking and projection filters. The manner in which the position and dimensions of the openings is determined is described. In Fig. 5 the films may be arranged with their lenticulation at an angle between 45 and 90‹.

Title: Apparatus for supplying water to fowls
IPC: A01K39/02
Filed: 1966-10-07
Abstract: 1,102,676. Drinking appliance for fowls. H. W. HART MFG. CO. 7 Oct., 1966 [8 Oct., 1965; 16 Sept., 1966], No. 44990/66. Heading A1M. [Also in Division F2] A system for supplying water to chicken includes a conduit 10, a drinking cup, and a water supply valve 18 including a displaceable plunger 26. A member 28 made of polypropylene and being buoyant in water is pivotally mounted in the cup. The system also includes either a vertically movable water tank (Fig. 8) or a number of stationary tanks (Fig. 9, not shown) being supported at different heights and being connected to the conduit 10. Therefore by varying the position of the movable tank or by selecting one of the stationary tanks the pressure of the water in the conduit 10 may be varied. The system with the buoyant member functions in three ways depending on the pressure of water. Firstly the pressure is so chosen that the weight of the member 28 alone displaces the plunger 26 to open the valve when the water level drops. The valve is closed when the member is raised by the water in the cup. The member therefore acts automatically as a float. Secondly a slightly higher water pressure is chosen so that the valve will remain closed even when the water level drops below the member. Further supply of water is dependent on a chicken attracted by water in recess 44 pecking the member to force it downwardly and to open the valve. The valve remains open until the member is raised by the water since the chosen water pressure drops when the valve is opened and is then insufficient to overcome the weight of the member. Finally the water pressure is so selected that water will only be supplied to the cup when a chicken pecks the member to open the valve. When it is desired that the valve should not be actuated automatically the buoyant member may be replaced by a smaller non- bouyant member (Fig. 6, not shown). The conduit 10, and cup 14 are preferably made of plastics material, and ferrule 22 may be made of brass in which case an elastomeric valve member 18 may include a copper inhibitor to prevent chemical interaction. in the embodiment of Fig. 11 a fixed tank 116 supplies water at a constant head e.g. 40 inches to drinking cups each comprising a buoyant pivoted member with a removable insert 124. With the insert the member operates automatically as a float, and without the insert flow of water into the cup is dependent on a chicken pecking the member.

Abstract: 1282717 Valves LEYLAND GAS TURBINES Ltd 20 Aug 1969 [26 Sept 1968] 45760/68 Heading F2V [Also in Divisions F1 and H1] An acceleration control arrangement for a gas turbine engine including a compressordriving turbine and a power turbine comprises a piston 18 which is depressed, as by the accelerator pedal of a road vehicle, when acceleration is required. The piston movement is transmitted, via a spring 22, a member 15 and a diaphragm 16, to the head 14 of a valve stem 13 to open a valve 9 against the action of a spring 10. Control fluid is then admitted from an inlet 2 via a fixed orifice 11, the valve 9, and a space 5 to an outlet 3 and thence to the control member of a fuel pump to cause more fuel to be supplied for acceleration of the engine. In addition, a plunger 19 actuates a microswitch 21 which causes a solenoid valve to supply fluid to an actuator which increases the area of the admission nozzles of tne power turbine. The space 5 and other parts of the ducting leading to the fuel pump control member form an accumulator supplied with fluid through the restricted orifice 11. The pressure in the space 5 is therefore initially low when the valve 9 is opened but increases progressively until after a predetermined time it is sufficient to move the diaphragm 16 back to its original position against the action of the spring 22 so that the valve 9 re-closes and the switch 21 returns to its original condition even though the piston 18 has not been released.
