Patent DE-3330514-A1 (DE)
Title: Two-shell folding wall which can be pulled out smooth
Inventor: KINDLER ADOLF DIPL ING
IPC: E06B3/48
Filed: 1983-08-24
Abstract: For the arbitrary division of adjacent rooms e.g. in flats, restaurants, offices etc., use is made of folding walls which are collapsible inter alia in a longitudinal axis and consist of interconnected elements. When not in use, i.e. when the folding wall is intended to be open, the same is folded together in a concertina-like manner into a "packet" position. In the operating state, in other words when room division is to take place, these folding walls are to have an essentially smooth and plane surface, and they are to be capable of being manufactured alternatively with good or increased sound insulation and to take up as little space as possible in the packet position. The folding wall according to the present application consists, apart from the end pieces which are manufactured essentially with half width, of mutually alike uprights and lamellae, the latter being capable of being manufactured comparatively wide in the case of the present construction. In relation to other previously known constructions, the danger of catching fingers during closing the folding wall is in this case avoided, as is the collision of adjacent structural parts which is otherwise brought about by the construction and which leads to annoying banging noises. Attached as characteristic illustrations are diagrams 1, 2 and 3 of the application, which illustrate the folding wall in particular in the characterising positions: "Folding wall closed" = Diagram 2 and "Packet position" = Diagram 3. <IMAGE>

Title: Method and device for producing shirt sleeves from a sleeve blank
Inventor: KEETON JOHN HERBERT
IPC: A41H43/02
Filed: 1983-09-07
Abstract: For automatically producing shirt sleeves from a sleeve blank, the latter is conveyed by a first conveyor (22) in a first direction (A). In doing so, a seam is formed along a first edge. The seam is ironed in an ironing station in the region of a pressure belt arrangement (33). The ironed sleeve blank is automatically taken from the first conveyor (22) and folded about a centre-line which lies largely transversely to the first conveying direction (A). The folded blank is placed by a material gripper (45) on a second conveyor (72) which conveys it in a second direction (B) largely transversely to the first conveying direction (A). A seam is sewn along a second edge of the blank by a second sewing machine (77) during transportation by the second conveyor (72) to form a shirt sleeve. A roller, rotating at a different speed from that of the second conveyor (72), grips the sleeve blank and moves it in such a way that at least one part of its second edge can be provided with a curved seam. <IMAGE>
Patent DE-3335742-A1 (DE)
Inventor: MILICIC DRAGAN DIPL ING
IPC: F02B75/02
Filed: 1983-10-01
Abstract: A rotating piston internal combustion engine with a housing (2), a rotor (3) and a double sleeve shaft (4). An uneven number of piston blades (5-9) is mounted on the rotor (3). In the area between adjacent piston blades, the rotor (3) has semi-hemispherically shaped combustion basins (10-14) connected by channels (16) with the double sleeve shaft (4). The channels are axially staggered and therefore connect with axially staggered areas of the perimeter of the double sleeve shaft (4). The double sleeve shaft (4) is driven in the same rotational direction with half rotational speed of the rotor (3). The gas exchange occurs through slits (19, 20) arranged alongside one another on the perimeter of the double sleeve shaft, through which the gas-air mixture is brought to the working chambers (I-V), or exhaust gas is evacuated. The pairs of slits (19, 20) one for each working area (I-V) are staggered on the perimeter of the double sleeve shaft (4) in such a way that a four-cycle operation is carried out in connection with the half rotational speed of the double sleeve shaft (4) in relation to the rotor (3). The internal combustion engine covered by the invention when compared with known motors is more simply constructed, cheaper in price, more economical in consumption and has good exhaust gas values due to its good combustion performance.

Title: Valve arrangement for piston or diaphragm force pumps
Inventor: RICHTER SIEGFRIED
IPC: F04B43/02
Filed: 1983-12-27
Abstract: In the valve arrangement for piston or diaphragm force pumps, whose pump chamber (44) on the one hand communicates, via a suction orifice (15) and a suction valve (22), with a smaller-diameter suction duct (18), and on the other hand communicates, via a discharge orifice (16) and a discharge valve with a larger-diameter discharge duct (19), the end of the suction duct (18) facing the pump chamber (44) and the side of the discharge orifice (16) facing away from the pump chamber (44) are each provided with an annular seating face or seating edge for a closing means which can be moved into the suction orifice (15) or into the discharge duct (19). In order to achieve a simple, space-saving design, simple construction and low-noise, high pump performance, the closing means are each designed as sections (22, 30) which are cut out to an annular-like shape from a flexible sealing plate (20) and which remain connected to the sealing plate (20) by a bridge (21, 23). The sealing plate (20) is clamped between two bodies (3, 17), each of which has recesses (24, 34) in the area of the bridges (21, 23), in order to avoid the bridges (21, 23) being subjected to compression forces. <IMAGE>
Patent DE-3400125-A1 (DE)
Title: Photographic paper base
Inventor: ROSENFELD KLAUS DR
IPC: D21H17/43
Filed: 1984-01-04
Abstract: Photographic paper bases consist of a substrate paper or base paper which is extrusion-coated on both sides with a polyolefin film. The paper must be sized with conventional hydrophobic agents in such a way that as little as possible of the developer solutions can penetrate into the cutting edges in the baths for developing the light-sensitive emulsions. In addition, the polyolefin films must adhere well to the two paper surfaces and must not delaminate either at the cutting edges or from the surfaces under the conditions of the downstream processing stages. This adhesion is considerably increased by the good affinity of an ethylene/acrylic acid copolymer applied to the paper surfaces, as compared with extruded polyethylene, if, simultaneously with this application, further components such as electrolytes for increasing the conductivity of the paper surface and starch derivatives or polyvinyl alcohols for increasing the stiffness as well as optical brighteners for adjusting the colour are applied in a stable dispersion. This application can also be additionally crosslinked and consolidated by an admixture of polyamino-epichlorohydrin. A further improvement of the adhesion of the polyethylene film and the hydrophobic treatment of the base paper is achieved if an ammonia-containing solution of this copolymer is added to the fibre material mixture directly before the paper manufacture and precipitated by lowering the pH.

Title: Pollutant sensor for motor vehicles, protective working cabins, etc.
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H3/06
Filed: 1984-08-25
Abstract: It is known that sensors have a temperature-dependent display sensitivity. At the point of installation, in particular as pollutant sensors in cars for detecting air pollution, the said sensors are subjected to high fluctuations in temperature. Furthermore, the sensor's heater produces its own heat. In order to ensure a constant display even in the case of widely varying temperature fluctuations, it is proposed according to the invention that the sensor element (2) for detecting the sensor temperature be arranged directly on the sensor (1) so that both the temperature at the sensor (1) and the conduction away of heat, which is increased at this point by convection, can be detected. The sensor heating voltage is controlled by the sensor (2) to produce a constant heating temperature. <IMAGE>
