Title: Seal for rotary piston engine - uses sealing ring assembly with side surfaces having sealing gaps
Inventor: KRAIC OTTO DIPL ING
IPC: F01C19/10
Filed: 1992-06-27
Abstract: The sealing system is for an internal axis rotary piston engine. The outer surface (9) of a sealing ring (8) is pressed against a housing (11). The side surfaces (15,16) of the sealing ring are held contact-free at a sealing gap distance from the groove walls (13,14) such that a minimum width of the sealing gaps is ensured mechanically by the guide surfaces (23,24). USE/ADVANTAGE - Seal for rotary piston engine. Because the guide surfaces are relieved of the axially acting forces of the medium to be sealed, the sealing action is essentially friction and wear free.

Title: Chimney with waste-gas line
Inventor: SCHNEIDER GUENTHER DIPL ING
IPC: F23J13/02
Filed: 1993-03-10
Abstract: The present invention relates to a chimney (1) with a concentrically or coaxially arranged waste-gas line (6) for channelling away the combustion gases. The chimney (1) comprises individual casing blocks (2) which are positioned vertically one upon the other and consist of gas concrete, while the waste-gas line (6) is made up of pipe pieces and shaped pieces (4) which are plugged one into the other on site. For operation independent of room air, the external diameter of the waste-gas line (6) is smaller than the diameter of the through-passage opening (3) of the casing blocks (2), this resulting in an annular ventilation gap for guiding fresh air. A heat-insulating pipe (7) consisting of mineral-fibre insulating material may also be arranged between the waste-gas line (6) and the inner wall of the casing blocks (2) which form the chimney (1). The chimney can be easily produced and assembled and, in comparison with conventional systems, is of a considerably lower weight while having a high degree of heat insulation. <IMAGE>

Inventor: SEIDLER KLAUS
IPC: F27D7/06
Filed: 1993-03-12
Abstract: The method and appts. for purifying molten aluminium by means of an inert gas under vacuum conditions are characterised by the following features: (a) the inert gas treatment takes place after molten aluminium has been transferred into a vessel (1) intended for its transport; (b) the treatment - which consists of maintaining a vacuum for 1 to 10 mbar, blowing in an inert gas and stirring - begins when a special head section, (2) with an integrated stirrer mechanism (10) and vacuum pump connection (15) has been set alright onto the vessel and (c) after the treatment the head section is taken off, the reaction products from the melt surface are removed and the vessel is closed (for immediate transport) with a transport lid. The inert gas (argon and/or nitrogen) is introduced into the melt by one or more blow lances. Alternatively, it is introduced via a gas duct surrounding the stirrer shaft rotating at 100 to 500 rev/min. ADVANTAGE - Air and moisture contacts of molten aluminium in transport is reduced.

Title: Fitting for scaffolding boards of structural scaffoldings
Inventor: NEUBAUER MICHAEL
IPC: E04G5/08
Filed: 1993-03-31
Abstract: The invention relates to a fitting for scaffolding boards of structural scaffoldings, comprising a box-shaped sheet-metal housing (1) which encloses in each case the face sides and the end portions of the scaffolding boards and is fastened thereon. The object of the invention is further to develop such a fitting to the effect that the outlay for the production and attachment is considerably reduced, the intention being for the strength and the service life to be increased at the same time. In order to achieve this object, the invention proposes that the sheet-metal housing (1) be designed as a deep-drawn part. Expediently, the sheet-metal housing (1) is deep-drawn from an already zinc-coated semifinished product or sheet metal instead of carrying out corrosion protection on the finished, bulky part. <IMAGE>

Title: Process and apparatus for the automatic packaging of rolls of material
Inventor: ROSCHER FRIEDER
IPC: B65D85/66
Filed: 1993-07-21
Abstract: The rolls of material are transported one after the other into a winding station and, there, are made to rotate about their longitudinal axis and thereby wind up with a web of packaging material. As soon as a predetermined number of layers has been wound up, the respective material roll is stopped and provided on both end sides with a disc consisting of inherently rigid packaging material, the discs exhibiting radially projecting teeth which project, all the way around, beyond the pertaining end surface. The projecting teeth are then bent over along beads and pressed against the circumferential surface of the material roll, to be precise in that region of the material-roll circumference which is next to be covered by the web of packaging material. Said covering takes place as soon as the material roll is made to rotate again. In this arrangement, the as yet upright teeth are progressively bent over and pressed against the circumferential surface of the material roll. In this manner, a cap which is integrated into the packaging web is provided on each end side of the material roll. The packaging web is coated over the entire surface area with adhesive during the second winding step. The packaging operation can be controlled in dependence on the previously determined diameter of the material roll which is to be packaged.

Patent DE-4333968-A1 (DE)
Title: Bicycle
Inventor: KERNER FRANZ DR ING
IPC: B62M3/04
Filed: 1993-10-05
Abstract: The bicycle has a front wheel, a rear wheel and a pedal crank which has two pedal arms directed oppositely to each other. A pedal is provided on them. In such bicycles, the length of the pedal arms of the pedal crank can be changed. They are set to the desired length before the journey and remain unchanged during the journey. In order to avoid signs of fatigue during the journey, the effective length of the pedal arms can be changed during a 360 DEG rotation. Since the effective length of the pedal arms changes during a 360 DEG rotation, the sequence of movements of the cyclist also constantly changes. As a result, signs of fatigue during longer journeys are avoided in a simple manner. The bicycle is suitable for longer journeys and also for physiotherapy devices since overexertion of the muscles, the joints and the like is reliably avoided.

Title: Liquid jet printing method
Inventor: DAUER HORST
IPC: B41J2/07
Filed: 1993-11-25
Abstract: In the liquid jet printing method drops of the liquid are selectively charged by a control voltage in the form of electrical impulses between the jet and a charge electrode. The control voltage has a flattened temporal waveform with regard to the rectangular waveform by use of a RC member. The continuous temporal waveform of the control voltage is converted into a step-shaped discrete waveform by use of a DAC (B). The clock frequency of sampling corresponds to the frequency of the synchronisation signal. One cycle is expressed in the temporal step width of the waveform of the control voltage.
