Title: Vacuum sewer systems including collecting tanks
IPC: E03F9/00
Filed: 1976-04-22
Abstract: 1502552 Vacuum sewer system for water closets IFO AB 22 April 1976 [23 April 1975] 16361/76 Heading E1C In a vacuum sewer system wherein waste from a flushing w.c. having a small water content is sucked through a pipe 6 into a collecting tank 3, the tank contents are circulated by a pump 1 through pipes 2. 4 and a venturi 5-7 which provides the suction in pipe 6. The pump 1 serves to comminute the waste, which is aerated at the venturi 5 by mixing with air admitted to pipe 6 at each flush. In the embodiment shown the pump 1 runs continuously and can also be used, through change-over valve 13, to empty the tank through outlet 14. In a modification, Fig. 2 (not shown), the pump (1) is switched on and off by a relay (10) of a sensor (9) in response to the vacuum level in a section of pipe (6) between the w.c. and a non-return valve (8). In this modification the tank (3) discharges into a conventional sewer through overflow (12).

IPC: B62D7/22
Filed: 1924-08-30
Abstract: 244,007. Lanchester, F. W. Aug. 30, 1924. Non-reactive steering-mechanism.-Comprises damping-mechanism for steering-gear of the kind employing a double-acting piston and cylinder, the piston being furnished with valves which permit of free movement when the steering wheel is operated but which prevent the free operation of the steering wheel from the road wheels. According to the present invention in damping mechanism of this kind a certain amount of leakage past the piston is provided to permit of a damped movement of the piston under the influence of forces acting on the road wheels. In the construction shown the cylinder c<2> is fixed to the front axle and encloses a radial piston a<1> integral with a hollow shaft a<2> to which an arm a<3> controlling the road wheels is fixed. The operating shaft b<2> passes through the hollow shaft a<2> and is formed with a foot b<1> carrying a stud b<4> projecting loosely through an opening in the piston, and adapted to open one or other of two sets of spring- pressed non-return valves a<4> provided in the piston. Normally the valves are held on to their seats by their springs but when the steering-shaft b<2> is rotated one set of valves is opened and allows the piston to be moved toward them and the steering arm a<3> to be rotated. Leakage past the piston is provided either by means of a needle valve controlling a vent in the piston or by making the piston an easy fit in the cylinder. The cylinder may be kept full of oil by a reservoir d<1> communicating with the piston by ducts d<4>. In a modification the damping mechanism may be combined with worm steering-gear in which the worm-wheel is fixed on the shaft b<2> and the whole gearing is enclosed in an oil-bath.

Filed: 1961-05-08
Abstract: A coating film is formed on articles by vapour deposition, the articles being moved freely in a substantially random manner.  The apparatus for carrying out this process suitably comprises a tumbler drum which is rotated sufficiently slowly to prevent the articles from being retained on the surface of the drum by centrifugal force. The coating of ceramic tubes with chrome-nickel, nuts and bolts with cadmium or tin and plastic screw caps with metals is disclosed.  To reduce abrasion the drum may be made of a material of low surface hardness, or at least one internal surface may be coated with such a material. There may be more than one vapour source which may be positioned outside a perforated inner tumbler drum.

The topping device comprises a disc 18 driven from the tractor engine and preceded by a feeler gauge 17 to which it is connected and by which its position is controlled. The beets are delivered by the digging share 27 to the conveyer 52 which comprises a series of rotating shafts 57 carrying fingers 58, the shafts being driven from the tractor engine. The conveyer 52 feeds an elevator 82 comprising chains 96 interconnected by tine-bars 93. The beets are dumped by the elevator into the trailer truck. The elevator is pivoted at its lower end to the rear part of the conveyer and is supported by links 86, 103 movable by the rotation of a shaft 87. The shaft is rotated by the movement of an arm 38 under the control of hydraulic cylinder, Fig 3 (not shown). The arm 38 also lifts the share 27 and the topping unit 16, the latter having a lost-motion connection with the lifting arm 38, which permits limited floating movement. When the elevator has been lifted, the trailer truck can be tilted by hydraulic cylinders fed from an oil pump on the tractor. The feeler 17 is manually adjustable relatively to the topping disc by movement of a lever 24.

Abstract: 785,593. Laminates. RITTER, E. J., [trading as GES. FUR WERKSTOFF-FORMUNG E. J. RITTER KOMM.-GES.]. May 7, 1953, No. 16812/57. Divided out of 785,592. Class 140. [Also in Group XV] In composite sheets or shaped members in which a core layer of fibres or shavings or both and a binding agent is united with covering layers impregnated with thermoplastic or hardenable synthetic resin by hot-pressing to consolidate the core and to liquefy and in appropriate cases to cure the resin, the fibres or shavings are used in such manner that locally-differing flow of resin or locally-differing pressures occur in at least one covering layer during the hot-pressing operation. The covering layers may be of paper, asbestos, textile or glass fabric, or wood veneer, and the synthetic resin may be phenol-, urea-, or melaminealdehyde. Coarse shavings may be used in the outer region of the core layer adjacent the covering layer which may be impregnated with excess resin. Alternatively, the fibres or shavings may be irregularly distributed to produce local accumulations or may vary in hardness or absorbency. The variations in consolidation produce local variations in the translucency of the covering layer giving marble or cloud-like effects. If the covering layer consists of separate superposed layers having different colours, e.g. yellow and blue, there will be local variations in the way in which the two colours combine to form a secondary colour, e.g. green. Melamine-aldehyde resin may be used for impregnating the covering layer or the outermost separate layer of the covering layer, while less expensive resins are used for the inner separate layers and the core, e.g. a urea-formaldehyde resin for the inner separate layers and phenol- or cresol-aldehyde for the core and, if desired, for the innermost separate layer.
