Title: Electric heating installations
IPC: G05D23/19
Filed: 1975-04-08
Abstract: 1502303 Storage radiator control systems ELECTRICITE DE FRANCE SERVICE NATIONAL 8 April 1975 [14 June 1974] 14395/75 Heading H2H A system for controlling a storage heater having means for accelerating the discharge of heat therefrom comprises thermostatic means for controlling the heating of the storage heater and the accelerating means together with a changeover switch operable by a time of day mechanism so that the storage heater is normally energized during an off peak supply period and the accelerating means is normally energized during the peak supply period. A storage heating device is provided with a heating element 10 and a fan 11 for accelerating the discharge of heat from the heat storage device, the control system including a change over switch 14 operated by a relay 17 energized by way of a cyclically operated tariff changing element 13, the switch 14 assuming the upper position during the off peak periods. The control system also includes thermostat contacts 12A, 12B, 12C responsive to the temperature of the room containing the storage heating device. Contacts 12A are arranged to open at 19‹ C., contacts 12B at 18‹ C. and contacts 12C at 20‹ C. Thus during an off peak period with the switch 14 in contact 16 A the heating element 10 will be energized whenever the room temperature is below 20‹ C. since contacts 12C will be closed. If, during this period, the room temperature falls below 18‹ C. contacts 12B will close to energize the fan 11 so increasing the discharge rate of heat from the storage heating device. During peak periods the switch 14 will be on contact 16B so that the contacts 12C now control the fan 11, the fan then being driven to maintain the room temperature at 20‹ C. If, during this period, the heat stored is insufficient and the room temperature drops below 19‹ C., contacts 12A close to energize the heating element 10, with the fan 11 continuously energized by way of the closed contacts 12C so as to maintain the room temperature maintained at 19‹ C. In a second embodiment the contacts 12A, 12B, 12C are replaced by solid state elements controlled by a thermistor and a potential divider.

Abstract: 1,027,735 Movable weirs. H. KOPPERS G.m.b.H. April 10, 1963 [April 14, 1962, Aug. 23, 1962], No. 14409/63. Heading E1H. An adjustable overflow weir comprises an impounding plate 2 (Fig. 1, not shown) having a cylindrical surface, a bearer tube 3 disposed on the axis of the cylinder of said surface and rotatably mounted at its ends, bearer plates 5 extending radially from the tube to the impounding plate, which plate co-operates with an impounding wall 6 adapted (at 8) to the impounding plate curvature, and a seal 9 preventing the liquid from running beneath the weir. A vertically adjustable downflow box in the liquid 1 feeds liquid through a conduit 16 into a float 11 allotted to the impounding plate, the float having a discharge conduit 17. When the water level 20 is at the prescribed height liquid flows through conduit 16 into the float at the same as it is discharged via conduit 17 so that the impounding plate 2 is held at the desired level. A change of level of the liquid 1 causes a change in the rate of inflow into the float, hence a change in the buoyancy of the float and consequent movement of the impounding plate.

Class 39(1) A screen comprises a multiplicity of discrete electron sensitive light-emitting elements backed by an electron permeable layer also forming a multiplicity of substantially concave miniature light reflectors each of which backs and optically isolates an individual light-emitting element. A mosaic of discrete dot-like phosphor areas 15, .005-.015 inches in diameter, are laid down on a glass support by printing through a stencil and a silk or metal gauze screen. The surface of the dot layer is then coated with a film 16 e.g. of aluminium which flows to an undulating contour so that each individual reflector 16a, 16b encloses a phosphor dot. The dot layer may be of phosphors of differing colour responses red, blue and green. In a modification, Fig. 4 (not shown), the screen is of tricolour line type and the sub-miniature reflectors are trough shaped. The aluminium layer is applied by first covering the phosphor with a vaporizable substance, e.g. collodion, and the metal evaporated on in a vacuum, the collodion being removed by heat allowing the aluminium to settle.

Title: Dry sprinkler for use in a fire extinguishing system
IPC: A62C37/08
Filed: 1978-04-14
Abstract: In order to avoid corrosion and deposits of lime and slurry in the interior of a dry sprinkler enclosed by a tubular casing (3), said sprinkler is provided with an axially displaceable pre-sealing member (27), at the water-supply-side end of which there is seated a sealing part (17) which, in the rest state of the sprinkler, blocks the water supply to the sprinkler nozzle (4), in the region of a sealing bore (23). The said sealing part (17) is seated at the rear end of a spacing rod (14) which is guided in the tubular casing (3) and the front end of which is pushed, in a spring-loaded manner, against a closure element (10) which is acted upon by the locking force of the sprinkler-triggering member and belongs to the sprinkler nozzle opening (13). If the sprinkler-triggering member (9), on heat-induced actuation, no longer exerts any locking force, the spacing rod (14), both under the pressure of an axially effective spring (25) and under the water pressure acting on the sealing part (17), pushes the closure element (10) away from the nozzle opening (13). In this arrangement, the sealing part (17) releases the sealing bore (23), with the result that the extinguishing water flows through the tubular casing (3) of the sprinkler and can reach the baffle plate (7) via the nozzle opening (13). <IMAGE>

Abstract: 1,070,826. Conveying material from the working face in mines. JOY MANUFACTURING CO. April 8, 1965 [April 17, 1964], No. 14898/65. Heading B8E. Coal fed from a mining machine (not shown), is distributed rearwardly (to the right in Fig. 1) in a hopper 10 by screw conveyers 92, 94. When a shuttle car (not shown) engages a member (119), (Fig. 2, not shown), at the output end of a conveyer 22, the latter is caused to start running and coal is fed from the hopper 10. After the car is filled and disengages from the member (119) as it commences it journey to a main conveyer, the conveyer 22 stops, but the mining machine continues feeding the hopper 10. Plates 106, 108 assist the correct feed from the extreme forward end of the hopper. The screw conveyers 92, 94, may be replaced by three screw conveyers disposed transversely of the length of the hopper 10 (Fig. 6, not shown). The screw blades at respective ends of each conveyer may be oppositely coiled so that coal at each side of the hopper 10 is fed to the centre as well as forwardly. In another modification (Figs. 7-10, not shown), the screw conveyers are replaced by a rotary conveyer, and in another modification (Fig. 11, not shown), by a pair of endless chain conveyers. In a further modification (Figs. 12, 13, not shown), a single endless scraper conveyer combines the functions of the screw conveyers and conveyer 22. In this form, the wall surrounding the conveyer at the output end, is formed with two hinged gates which are caused to open apart by engagement of the shuttle car. The rearwardly projecting (feeding) end of the conveyer 22 may be adapted to have a pivoting movement, either upwardly and downwardly, or transversely.
