Patent DE-3338197-A1 (DE)
Title: Cleaning system with pulsating compressed air
IPC: B08B3/02
Filed: 1983-10-20
Abstract: The invention relates to a cleaning system in which compressed air is fed to the liquid cleaning agent in pulses in order to reinforce the cleaning effect and to save cleaning agent. The components of the cleaning system are arranged in such a way that the compressed air for the mechanical cleaning, usually with an operating excess pressure of 3-7 bar, can also be fed to a stream of cleaning agent which is at several times the operating excess pressure of the compressed air. In order to prevent cleaning agent entering the area of the compressed air system, a combination of non-return valves is arranged, between which there is a transparent safety connection which, as a predetermined break point, permits the excess pressure to escape in the event of a functional fault of the non-return valves.

Title: Process for producing a sintered material, and material produced by the process
Inventor: ALBANO-MUELLER LOTHAR DR
IPC: C22C33/02
Filed: 1983-12-20
Abstract: The invention relates to a process and to a material consisting of a powdered mixture of iron, copper and solid lubricant in the form of molybdenum disulphide. Suprisingly, it has been found that molybdenum disulphide is preserved in the matrix even at the sintering temperature of 1120 DEG C, since the sintering is carried out in a reducing or neutral atmosphere, preferably in an atmosphere of about 5% to 30% of hydrogen, the remainder being nitrogen. This also results in a good thermal stability of the molybdenum disulphide, that is to say sufficient solid lubricant in the end product.

Patent DE-3416309-A1 (DE)
Title: Crank mechanism
Inventor: ZSCHERNITZ GUENTHER
IPC: B62M1/36
Filed: 1984-05-03
Abstract: The hitherto straight crank arms which connect the shaft and the pin are angled, it being possible to vary the degree of angling. The angling ensures that the connecting rod transmits energy to the crank pin until it reaches bottom dead centre. In the hitherto straight crank arm, the downward movement of the connecting rod ceases in a retarded manner at bottom dead centre. In the present invention, the downward movement of the crankshaft makes a direct and continuous transition into the upward movement, without retardation. In contrast to the hitherto retarded progress of the movement, this continuous movement of the crank pin and connecting rod gives rise to a fuel-saving and economical effect. To save fuel is automatically to emit less exhaust gas. Rounded continuous movements also contribute to smooth running of an engine. This sequence of movements will also have a favourable effect on all moving assemblies of the engine.
Patent DE-3418394-A1 (DE)
Title: Image recording and image processing methods and devices for airborne video cameras
Inventor: DIETRICH KLAUS DR
IPC: H04N5/335
Filed: 1984-05-17
Abstract: This image recording method is intended for use in airborne video cameras (3) which are equipped with light-sensitive semiconductor image sensors (1) which are arranged on a surface. In order to improve the imaging clarity and to reduce the influence of image explosion, it is provided that an electronic image intensifier (2) having an adjustable gain factor be connected upstream of the semiconductor image sensors (1), which image intensifier (2) is operated in a pulsed manner. In consequence, the semiconductor image sensors (1) are in each case illuminated only briefly, at an increased intensity, during one frame period. An image processing method, which is intended for the video images thus recorded, provides that actual data concerning the movements of the aircraft (1) are obtained continuously with the aid of movement sensors (9) and are transmitted to an evaluation station (10) together with the video data. A comparison of the actual data with the corresponding required data is carried out there, and the images are corrected with respect to their mutual position and orientation such that any deviation between the actual and corresponding required data associated with the time at which the respective image is recorded is compensated for. This results in a jitter-free image sequence.
