Title: Apparatus for curing extruded or compression-moulded articles from small plant parts mixed with binder
Inventor: HEGGENSTALLER ANTON
IPC: B29C48/91
Filed: 1982-02-18
Abstract: The invention relates to an apparatus for curing extruded and compression-moulded articles from small plant parts mixed with binder. It is known to make such a curing apparatus adjustable in one direction, in order in this way to vary the thickness of the pressboards. However, a one-dimensional adjusting capability is not sufficient for the variation of other extruded profiles. Therefore, with the invention it is proposed to form a curing channel of movable and fixed wall sections, it being intended for the respectively neighbouring longitudinal edges of these wall sections to be profiled in a manner of pinnacles, one pinnacle of a wall section in each case protruding through an assigned pinnacle gap of the other wall section, so that the wall sections are meshed with one another and consequently are adjustable with respect to one another only transversely to the longitudinal axis of the curing channel for changing the curing channel cross-section. The movable wall sections can be adjusted in several directions with freedom of movement over the pinnacle height, the adjustability in one direction being independent of the adjustability in the other direction. The adjustment is performed by means of lifting motors, which are mounted fixedly on the frame and, guided by means of pressure plates, act on the movable wall sections. <IMAGE>

Patent DE-3209378-A1 (DE)
Title: Venturi tube with variable cross-section
Inventor: LANGKITSCH HANS
IPC: F02M9/10
Filed: 1982-03-15
Abstract: The subject of the invention is a venturi tube (1) for controlling flows by varying its narrowest cross-section (10). The funnel comprises individual plates (12) which, when the cross-section is varied, slide over one another like scales as on a photographic diaphragm. The plates are swivel-mounted in the base plane (14) of the outlet funnel. In order to prevent secondary flows, the joints (59) between the plates must be sufficiently tight. This is achieved by means of a certain geometric shape of the large-surface joint walls (63/64). On the carburettor, with a venturi tube of this type a high degree of atomisation can be achieved over the entire output range and, with simultaneous control of the fuel feed (141), a constant mixing ratio, and thereby greater economy and cleaner exhaust gas. Throttle valve and compensating nozzles are not necessary. <IMAGE>

Title: Method of cleaning floors, materials or the like, and device for carrying out the method
Inventor: KULLIK GUENTER R J
IPC: A47L9/02
Filed: 1983-03-19
Abstract: In the method according to the invention for cleaning floors, materials or the like, the working air flow produced by a suction fan is applied to a partial region of the nozzle, which forms a throughflow region for the working air flow sucking up the dirt particles. In this case, the throughflow region varies its position over the entire nozzle width. The device for carrying out the method has a vacuum cleaner with a suction nozzle which has a suction opening facing the floor and taking up approximately the entire width of the nozzle. Said suction opening is used for cleaning only in a small region - the throughflow region - per unit of time. In this case, the throughflow region is continuously displaced along the suction opening so that during cleaning there is a cleaning effect of the nozzle over its entire width despite the small throughflow region.
