Filed: 1979-12-13
Abstract: A tapering flow duct is formed below a chassis having a caterpillar track and forms lateral openings between a cleaning brush and the tracks. The flow duct is connected through an opening to a suction duct of a suction pump which conveys the sucked up liquids with the contaminants contained therein into a filter. Due to the increased flow velocity, the static pressure in the flow duct is reduced, so that the chassis is pressed onto the bottom surface and can overcome severe gradients without sliding.

Abstract: A process and apparatus for washing fibre stock. The fibre stock is passed along a passage 14 from a stock inlet 15 to a stock outlet 16. The passage is defined by a portion of the inner surface of a substantially horizontal cylindrical screen 4, preferably a wire gauze. Washing liquid such as water is introduced into the passage, preferably by means of apertures 9 in a longitudinally extending hollow member 8. Effluent liquid passes through the screen, for extraction e.g. through outlets 24 and 25. To enable the washing of stock of high consistency e.g. up to 8%, while avoiding plugging of the screen 4, the arrangement is such that the stock only partially fills the cylindrical screen and is subjected to a tumbling action by the rotary movement of the cylindrical screen as the stock moves along the passage 14 to the stock outlet 16. The hollow member 8 is displaced downwardly from the axis of the cylindrical screen, so as to be positioned within the tumbling stock. In an alternative arrangement, the screen is defined by an endless belt carried over a series of rollers and having a portion of upwardly concave cross-section.

Abstract: A chair provided with a seat carrier and an associated backrest carrier includes a pneumatic spring connected between the seat carrier and backrest carrier, and a mechanical draw spring one end of which is connected directly to the backrest carrier and the other end of which is connected to an adjustable lever pivotally mounted on the seat carrier. The pneumatic spring and mechanical spring are disposed in side-by-side parallel relation to one another between a pair of generally vertical spaced bars forming a portion of the backrest carrier. The force exerted by the mechanical spring is in opposition to the restoring force exerted by the backrest carrier so that movement of the lever to increase the force exerted by the mechanical spring reduces the total restoring force exerted on the backrest carrier.

Abstract: In the production of rows of nails in running lengths or measured lengths for use in nail guns, the nails (3) are placed in a row of parallel grooves (2) in the periphery of a wheel (1). A groove (7) extending along the periphery of the wheel is approximately as deep or a little deeper than the grooves (2) and intersects the grooves (2) at the centre thereof. Bands (8) are applied on both sides of the groove (7) in spaced relationship with the groove, and a third band (9) is applied on top of the bands (8) to form a cavity defined by the bands (8 and 9) and by the wheel periphery with the groove (7). Liquid resin is introduced into said cavity and solidifies to form a panel (10) which abuts the row of nails and has projections extending between and gripping at least partly around the nails.

Abstract: A joining arrangement (1) for extended scaffolding elements (4,5) in building scaffolding is intended to join one end (3) of one scaffolding element (4) to one end (9) of another scaffolding element (5). A first part of the joining arrangement forms a female component (2) and a second part of the joining arrangement forms a male component (9) which, in the joined state, extends inside the female component. The female component and the male component exhibit joining surfaces extending essentially concentrically with one another and facing towards one another. The joining surfaces are so dimensioned as to cause a space (17) to be formed between them, and one of the joining surfaces exhibits at least one set of at least three peripheral, symmetrically positioned and radially facing local areas (18, 19) raised above said joining surface. These form load-bearing supporting organs located at a certain distance from one another for the opposing joining surface (21).

Abstract: An air-compressing, direct-injection internal combustion engine formed with a combustion chamber in the shape of a solid of revolution in the piston crown into which fuel is injected via only one jet through an injection nozzle arranged obliquely in the cylinder head, in the direction of the rotating air for combustion. The working of the internal combustion engine is proposed to be improved in such a way that fuel deflection liable to occur in all operating ranges, mainly at the start and at the end of injection due to the rotating air flow and, respectively, when the gas is flowing out of the combustion chamber after the top dead center position, is prevented from affecting the working of the engine and from producing erosion on the piston crown and/or cylinder head. According to the new disclosure, this is essentially achieved by having the fuel jet discharge point of the injection nozzle at top dead center of the piston lying below the piston crown level and projecting into the combustion chamber, and by having the injection nozzle surrounded, with a clearance, by a longitudinally slotted sleeve which is open at the end and projects beyond the discharge orifice (fuel emission point).

Abstract: A filter for a cigarette includes a porous filter rod circumscribed by a porous or air permeable wrapper, and ventilating air grooves embedded in the wrapped filter rod which extend from one end of the filter rod a preselected distance generally longitudinally thereof. The wall of each of the grooves defined by the wrapper is impermeable to air and smoke while at least a portion of the remaining area of the wrapper is air permeable. An air permeable tipping material circumscribes the wrapped filter rod which provides a path for ventilating air flow into the filter rod and a path for air flow into the grooves. Due to the air impermeable wall of the grooves, the air flowing in the grooves is segregated from the air and smoke flowing through the filter rod so that ventilating air is the only substance flowing in the grooves. The air flowing through the tipping material into the filter rod co-mingles with and dilutes the smoke flowing through the filter rod before it reaches the smoker's mouth.

Abstract: An apparatus for drying compressed air operating according to the principle of the two-vessel air dryer is described, having two air dryers (14, 15) operating alternately in intervals in the drying phase and regeneration phase and having a throttle valve (26) for impinging the particular air dryer (15 or 14) in the regeneration phase with a part-stream of air taken from the outlet of the air dryer (14 or 15) operating in the drying phase, in which apparatus, for the purpose of achieving optimal regeneration with regard to compressed air consumption and efficiency, the throttle valve (26) has a constriction which is adjustable depending on the overall air flow rate. The adjustable constriction in this case is designed in such a manner that the ratio of the overall air flow rate through one air dryer (14 or 15) during the drying phase to that of the part-stream of air branched off from this by the throttle valve (26) remains essentially constant and is preferably 100:15 (Figure 1).

Abstract: Honeycomb floor panels for use in elevated floors or the like are disclosed. The honeycomb structure provides similar metal strips providing lateral cuts along one edge providing angulated tabs. The angulation of the tabs provides an angulated throat having a width substantially greater than the thickness of the strips so that the strips can be assembled in an interfitting relationship while the strips of the two arrays are angulated with respect to each other. After assembly, the arrays are moved to a substantially perpendicular position, and in such position a tight fitting relationship is achieved to eliminate looseness. Such honeycomb is provided, in accordance with one embodiment, with upper and lower metal sheets which are welded or otherwise fastened to the honeycomb itself. In such embodiment, an additional upper surface sheet is provided to prevent denting and to distribute concentrated loads to prevent crushing of the honeycomb. Sound deadening is provided between the two upper sheets. In another embodiment, the honeycomb only extends a portion of the distance from the bottom of the panel and is embedded at its upper edge in a layer of lightweight concrete. The concrete provides the load bearing surface of the panel.
