Filed: 1927-11-14
Abstract: 306,169. Wolf, P. Nov. 14, 1927. Addition to 206,151, and 254,709, [both in Class 82 (ii), Washing granular &c.J. Ball and float valves.-In a coal-washing jig of the kind described in the parent Specifications, a valve 16 controlling the escape of air from a compartment 8 is actuated by a float 20 which rests partly in the coal 5 and partly in the shale. The spindle 27 of the rotary valve 16 is actuated by the float stem 21, chain 24 and sprocket 26, Fig. 8. in such a way as to open the valve when the float rises. The float acts against a counterweight 32, Fig. 2. which hangs by a rope over a cam 30 keyed to the shaft 27 so that the resistance of the weight is least when the float is in its highest position. The float may be cylindrical or tapered with its smallest diameter at the bottom. The float may also control a valve 16a admitting water beneath the piston 1 which produces pulsations through the washing bed.

The door is made of four clockwise rotating panels 10 of bullet proof plastics material, side wall 11A being lengthened and wall 11B shortened so that when the door is locked a person leaving can escape whereas the person entering cannot escape. The coils of the detector pass behind wall 11A, across the top half of the entrance, through spindle 12 and underneath the floor and provide a signal to sound an alarm and lock the door when a gun is detected on a person entering. One or more loundspeakers 15 may be provided to relay a message to the person trapped and shute 14 provided to allow the person trapped to pass out the alarm initiating metal object. The detector coils may be positioned on a wall adjacent swing doors, Fig. 3 (not shown), sliding doors or across a corridor.

Abstract: 884,420. Composite photography. BUSH & RANK CINTEL Ltd. Sept. 24, 1959 [Sept. 26, 1958], No. 30805/58. Drawings to Specification. Class 98(2). In order to enable the satisfactory production of a record of a naturally illuminated scene and an artificially illuminated display by simultaneous recording of images of the scene and display despite large differences between their levels of illumination, the recording medium employed is a photographic film comprising separate layers sensitive to light in respective non-overlapping spectral regions and the optical path for the naturally illuminated scene intrudes colour-selective means so that the images of scene and display are formed by light of different spectral conposition so as each to expose only one layer, whereby by subjecting the two layers to separate developing procedures satisfactory images of both scene and display may be obtained. Typically a bipack film comprising separate emulsion layers one sensitive to red and the other to green light is exposed simultaneously to a naturally illuminated scene and to a cathode ray tube display giving a green trace image, the two images being combined by a semi-transparent dichroic mirror which reflects green light from the display and transmits red light from the scene, a minus green filter being placed in the direct light path from the scene to the mirror. If desired a. filter could also be disposed between the mirror and the cathode ray tube.

In an assembly for interconnecting conductors, the terminals 40 of a group of conductors 42 are positioned in insulated relationship in shaped slots 34 in a dielectric wafer member 30 such that apertures in terminals 40 are coaxial with apertures 32 of the wafer member whereby pin members 22 carried by an insulating base 10 may be inserted through the wafer member 30 and through other similar members carrying terminals of other groups of conductors to electrically connect the conductors 42 with said other groups of conductors (Fig. 1, not shown). The terminals 40 are bifurcated and are sprung by insertion of the pins such that their contacting surfaces 46 firmly clamp the pins. The terminals snap into the shaped slots 34 of the wafer member. An axially movable locking bar carried by the base 10 has knobs 19, 20 at each end and may be placed in one of two positions such that grooves 16 or lands 17 register with grooves 26 in the pin members 22, thus unlocking or locking in place respectively the pin members. Fig. 3 shows another embodiment wherein the pin-carrying base 50 comprises a cover 52 and a pin holder 54 with two rows of spaced apertures 56 for pin members 58. Each pin member has a head 60 at one end with a circumferential groove (Fig. 4, not shown), the head preventing the pin from passing completely through the apertures 56. The two members 52, 54 are secured together by fasteners 68 extending through elongated apertures 70 and threaded apertures 72, the elongated apertures allowing the cover to be moved laterally to provide access to heads 60 of the pin members through apertures 74 of the cover (Fig. 5, not shown). The pins may then be removed by inserting a screwdriver blade into the grooves in the heads. The base 50 may be mounted on a bracket 78 and dust cover 80 may enclose it and wafer members 76 assembled therewith. The pin members and terminals may be fixed in their respective members and the pin members may extend in opposite directions from the base member. Again, individual pins may be inserted through a stack of wafer members.

Class 75(i) [Also in Group XXIX] A system for supplying atomized liquid fuel to a burner comprises a fuel control valve positioned close to the burner, an atomizing fluid control valve located relatively remote from said burner, pipe means for supplying atomizing fluid concurrently to said fuel control valve and said burner, and means operated by the pressure of the atomizing fluid to open and close the fuel control valve when the atomizing fluid control valve is opened and closed respectively. The atomizing fluid, which may be steam, is supplied through a pipe 22 to the fuel valve controlling device shown to raise a piston 21 against the action of springs 18 and to thereby lift a valve member 10 from its seat to allow fuel to pass from an inlet 12b to an outlet 12c. As soon as the piston 21 starts to rise it closes a port 19a connecting the space above the piston to atmosphere and just before reaching the top of its stroke it uncovers a port 17b so that steam is admitted to the space above the cylinder. The piston has a greater surface area below so that the steam maintains the piston in its raised position. When the steam control valve is closed the piston 21 is moved downward to close the fuel valve by the springs 18 assisted by the steam pressure above the piston.
