Abstract: ABSTRACT OF THE DISCLOSURE      The disclosure is directed to a rotary wall deslagger for cleaning boilers.  In accordance with the invention, an extensible rack element is selectively, mechanically coupled to a rotatable lance tube of the rotary wall deslagger to move the lance tube between a working and non-working position   When the selective mechanical coupling between the rack and the lance tube is released, the rack is extensible relative to the lance tube to activate a cleaning fluid discharge means and a driving means to impart a rotary motion to the lance tube.  In accordance with another feature of the invention, the selectively-operable, mechanical coupling is released after the lance tube has been moved to its working position and the cleaning fluid discharge means and the rotary drive means are activated by the rack element substantially simultaneously with one another so that the cleaning fluid reaches the discharge nozzle of the lance tube at full pres-sure as rotation of the lance tube begins.

Abstract: ABSTRACT OF THE DISCLOSURE     A component framework structure for a fold-able umbrella avoids channeled frame parts so as to make its various auxiliary stretchers fold into an abreast position instead of overlapping. Various stret-chers on both the left and right sides have flat and thin structures while their head joints are in conjunc-tion with an upper notch member of the umbrella where-by the joints are positioned under the bottom of the notch. The outside part of the joints thus does not protrude beyond the diameter of the upper notch, so that the tail part of the foldable umbrella, after it is folded up, becomes very slim with new practical effectiveness achieved in its carrying, packing and outer appearance.

Abstract: Attorney's docket 6975 CAN     INVENTORS: FREDERICK R. ARMSTRONG, HEINZ BRAUN, ALFRED BUBIK, HELMUT STORR and KARL TUROBIN-ORT INVENTION: TWIN-WIRE PAPERMAKING MACHINE     ABSTRACT OF THE DISCLOSURE     A twin-wire papermaking machine contains a headbox for forming a first fiber ply which is essentially down-wardly dewatered at a section of a first wire.  At the end of this wire section, forwardly or upstream of the inbound or on-running location of a second wire there is arranged a second headbox for forming a second fiber ply which is essentially  upwardly  dewatered  along  a  subsequently arranged common path of both wires.   The common path advantageously extends over an essentially water impervious, convex domed contact surface of a slide shoe and/or a jacket  surface  of  a  guide cylinder  or  roll.   During operation,  the second fiber ply is deposited upon the already extensively dewatered first fiber ply and upon passage through the common path of both wires this second fiber ply is dewatered upwardly away from the first fiber ply.  This enables separate dewatering of both fiber plies, and  there  is  particularly  avoided  deflocculation  of individual fibers,  and  thus,  impairment  of  the fiber formation in the initially formed ply.

Abstract: Spraybooth A spraybooth for use, for example, in spray painting motor vehicles has an air supply duct 11 which extends centrally along the length of the top 5 of the booth and has an air supply opening 12 fitted with a cloth filter 16 in its underside. The opening 12 extends from near one end 1 of the booth right up to the other end 2 and is supplied with air by a fan 9 from the one end of the booth. A single air outlet opening 17 is provided at the middle of the bottom of the one end 1 of the booth and is connected to an air extraction fan 21. The velocity head of the air flow from the air supply fan 10 decreases along the length of the air supply opening 12 from the one end 1 to the other 2 and accordingly the pressure head increases so that the downward air flow from the filter cloth 16 per unit length of the air supply opening decreases from the one end 1 to the other end of the booth 2. This arrangement achieves an extremely efficient downward air flow pattern in the booth with little or no turbulence so that, after sraying, droplets of paint with which the air in the booth is contaminated after spraying are not precipitated on the surface which has been sprayed.

Abstract: Abstract of the Disclosure An anti-theft device for an automotive vehicle such as a car or truck having fluid pressure-operated brakes. The device includes a lockable member that, when activated while the brakes have been applied by the driver, inhibits any substantial change in the then existing fluid pressure condition in the brake fluid pressure system of the vehicle. The brakes thus remain locked, preventing normal movement of the vehicle, even if the brake pedal is subsequently released and the engine is running. The device can also include an additional lockable member for immobilizing the brake pedal to prevent its being depressed. Optionally, the device can also in-clude one or more electrical switches which are operated, when either lockable member is activated, to ground out the distributor and/or open the ignition circuit at a point away from the ignition lock terminals, thereby to prevent starting of the engine. Prefer-ably a special key is provided for releasing the lockable member, and special screws, e.g. screws with non-conventional heads, can be used to assemble the device as well as to mount the operator-accessible parts of the device in the vehicle so as to make removal or disassembly of the device more difficult.
