Title: Conveyance of Material Requiring Hygienic Disposal
Inventor: HALLSTROM OLOF HENRIK
IPC: E04F17/10
Filed: 1966-07-29
Abstract: 1,199,917. Pneumatic conveyers; shoots. CENTRALSUG A.B. 27 July, 1967 [29 July, 1966], No. 34146/66. Headings B8A and B8S. An apparatus for collecting and conveying material such as garbage or soiled linen, comprises upright shoots 2, each having material entry doors 3, and a valve 4 normally closed to support the material in the shoot and openable to allow the material to pass into a suction duct 1 through which it is conveyed to a separation chamber 5. In a system for garbage, shown in Fig. 1, three air extraction pumps 12 are pneumatically coupled to the duct 1 through a fine filter chamber 11 and the separator chamber 5 which incorporates a coarse filter adjacent its upper end. A valve 4A at the upstream end of the duct 1 normally restricts the airflow into the duct such that a vacuum is maintained, but is opened prior to the opening of a valve 4, such that a high velocity air stream awaits the garbage and causes a high vacuum in the open shoot 2. The valve 4 is pivotally mounted and power operated to pneumatically seal off the duct 1 in its closed position and to locally admit air into the shoot and be scraped clean as it moves into its open position. In the embodiment of Figs. 7 and 7A (not shown), the valve plate rebounds in its open position to shake itself clean. The separator 5 comprises an inlet from the duct 1, below the coarse filter screen and an outlet for air above the screen, valves being provided at 8 and 9 so that the separator may be by-passed by the air. The by-pass is brought into operation when the separator is to be emptied by screw or scraper devices feeding an incinerator 6 on a container. Pressurized air is supplied via line 12D to the top of the separator during emptying, to clear the coarse filter. The fine filter chamber 11 includes a vibrating cloth screen through which air is drawn and from which dust is shaken on to an emptying valve in the chamber base. An interlocking system normally prevents the doors in the shoots from being opened when the shoot valve is open, but a pivoting hopper door, Fig. 16 (not shown) permits the entry of garbage into the shoot at any time. A spur 1c from the suction duct 1 may be provided to supply a system of vacuum points lE for domestic appliances. In a system for soiled bagged linen, Fig. 2 (not shown), the separator comprises a chamber into which the bags fall and from which the air is extracted, an airlock being provided to facilitate removal of the bags. Inwardly opening doors at the top of each shoot and restricted by-passes around the shoot valves facilitate a continuous reduced pressure in the system. Water injection may be provided for the system to prevent frictional electrostatic changing and abrasion of the bags. Each valve may be operated through a photo-electric device sensing the accumulation on top of the valve. In the embodiment of Fig. 3 (not shown), a garbage and soiled linen system are arranged in parallel to be coupled to a common suction source.

Title: Improvements in or relating to distance indicators
IPC: B60R7/04
Filed: 1934-11-30
Abstract: 439,079. Route-progress indicators. MIZON, K. L., 32, Parkside Street, and SMITH, A. J., 57, King's Place, both in Rosyth, Fifeshire. Nov. 30, 1934, No. 34418. [Class 118 (i)] A route-progress indicator on a vehicle comprises a double pointer 10, 101 which is moved behind a transparency bearing selected representations of the routes by means of a screw spindle 8 driven from the speedometer drive through a reduction gear and a variable friction drive 15, 16. Movement of the driving disc 15 across the driven disc 16 for the purpose of reversing the drive at the end of the journey is effected by linkage operated by a hand lever 26 on a spindle 27 but should the reversing operation be overlooked, the provision of unthreaded portions 57 at the ends of the screw spindle 8 allows the spindle to rotate freely in the pointer traveller 9. The range of the control lever 26 is adjusted by a screw 40, to compensate the speed of the spindle 8 for tyre wear. The shaft 14 carrying the friction disc 15 is carried by a bracket 21 movable about a pivot 22, a spring 25 urging the disc 15 against the disc 16. When reversing or adjusting by a hand knob 52, the friction disc 15 is withdrawn from the disc 16 by depressing a button 55 and swinging the bracket 21. The routes are represented on interchangeable transparent cards or on a translucent linen blind 5 which is moved on rollers across the pointer 10, 101 to bring the selected routes into position. The pointer carries an electric lamp 9<1> which throws the shadow of the pointer on the blind.

Title: Improvements in or relating to apparatus for starting internal combustion engines operated with volatile liquid fuels
IPC: F02N99/00
Filed: 1933-12-09
Abstract: 429,944. Starting ; admission devices for extra air. TWIGG, C. G., 58, Greys Road, Henley-on-Thames, and MERTON, H., Grove End, Sonning-on-Thames. Dec. 9, 1933, Nos. 34720 and 36249. [Classes 7 (ii) and 7 (v)] In a device for starting an engine operated with volatile liquid fuel fed from a tank 10, in which a conduit 16, in open communication with a closed space at the top of the tank above the free level of liquid therein, is connected to the induction system and a valve 22 for admitting extra air to the induction system is arranged to control the conduit, a spring 42 holds the valve in a position permitting the supply of vapour through the conduit when starting the engine. The valve casing 20 has a cylindrical chamber 21 in which the piston valve 22 moves endwise between an end wall 24 of the casing and the end 27 of an adjustable screw plug 28 having an axial bore 29 forming an air inlet. The branch 30 forming the vapour inlet opens into an annular groove 32 in the casing 20. The piston 22 is normally held on the seat 27 by the spring 42, which bears against a shoulder 44 in an axially adjustable tube 36 connecting the device to an induction pipe. Axial grooves 48 in the periphery of the piston 22 or the inner periphery of the chamber 21 admit air from the bore 29 when the piston is drawn by engine suction away from the seat 27. When starting, the piston 22 is drawn off its seat 27 by engine suction and vapour drawn through the branch 30 mixes with air drawn through the bore 29 to form a starting mixture. During normal running with a partly open throttle, the piston 22 occupies an intermediate position in the chamber 21 and extra air continues to be admitted. On fully opening the throttle, the decrease in suction allows the spring 42 to close the piston 22 on its seat 27 and air from the bore 29 is cut off ; air may, however, enter through the cap of the filling inlet 12 of the tank 10 and is mixed with any vapour remaining in the tank. Specification 407,439 is referred to in one of the Provisional Specifications, which describes also a T-shaped fitting on the fuel tank, comprising two L-shaped passages each opening through the downstroke of the T into the top of the tank. One passage is connected with an extra-air conduit leading to the induction system, and the other is controlled by a light ball or other non-return valve for admitting air to the tank. Reference has been directed by the Comptroller to Specification 25663/13, [Class 7 (ii)].
