Title: Calibration of spectral photometer to extra-terrestrial energy - using calibration factors obtained by diffusing disc and interchangeable wide angle lens
Inventor: BISCHOFF KARL-HEINZ DR
IPC: G01J1/00
Filed: 1980-11-08
Abstract: A calibration method and arrangement for illumination intensity and radiation density measurements are applicable to optical techniques, meteorology, and pref. remote reconnaissance of the ground. The method enables self-calibration of a spectral photometer to the extraterrestrial spectral energy distribution. The method does not require standard light sources and is used with a convenient spectral photometer design suitable for use in the field. The spectral photometer is calibrated w.r.t. the known extraterrestrial spectral energy distribution using a measurement aperture (6) and additional solar objective (1). Further measurements of extra-terrestrial energy distribution using the calibration factors obtained with the interchangeable calibrated solar objective are then performed successively with a diffusing disc (3) and interchangeable with angle objective (2). The dia. of the solar image is approximately half the dia. of the measurement aperture.

Title: Process and apparatus for feeding fuel into fluidised-bed furnaces
Inventor: SCHILLING HANS-DIETER DR
IPC: F23C10/22
Filed: 1981-01-22
Abstract: For feeding fuels into fluidised-bed combustion appliances, especially into fluidised-bed furnaces, in which the fuel is fed in above zones of the flow-on bottom with a reduced or completely prevented passage of the gases flowing upwards, there are arranged above the lateral edges of the middle zone (4) of the flow-on bottom vertical blind-like fittings (10) having blind slats (11) which are horizontal or which are directed downwards towards one another. In further embodiments, vertical blind-like fittings (10) having blind slats (11) which are horizontal or which are inclined downwards towards the lowest point of the furnace wall (1) are also arranged above the lateral zones (4) of the flow-on bottom which join together with the furnace wall (1). Larger fluidised beds can contain a plurality of zones (4) with a prevented passage of gas. Moreover, cooling tubes can be attached to the blind slats (11). A complete burn-out of the fuel particles in the fluidised bed is achieved, because no gas bubbles pass into the draw-in region for the supplied fuel and thereby impede the downwardly directed fuel flow. <IMAGE>

Title: Method of operating a heat pump as well as heat pump with a heat exchanger for implementing the method
Inventor: BEHRINGER EDUARD DIPL ING
Filed: 1981-03-24
Abstract: A heat pump installation has a heat pump as well as a heat exchanger accommodated in an insulating manner in a container. The heat exchanger is formed by a number of coil-like pipeline sets which pass through one another in regions in a comb-like manner and is thus compactly constructed. The flowthrough with the water which serves as heat source takes place transversely to the longitudinal extent of the pipeline sets, the pipeline turns forming flow guides. The container for receiving the heat exchanger is in the operating position accommodated inside the earth, preferably at a frostproof depth. According to the invention, water with a minimum water inlet temperature slightly above 0 DEG C is supplied to the heat exchanger, the water temperature behind the heat exchanger in the direction of flow remaining above the freezing point of water. There is thus no ice formation on the heat exchanger surfaces even in the case of the abovementioned low water temperatures.

Title: Compressed air-driven starter for internal combustion engines with automatic switching over to the compressor
Inventor: ZEMANN HERBERT
IPC: F02N7/08
Filed: 1981-04-16
Abstract: The starter starts the engine by means of compressed air. Weak points of electrical starter systems: leads, contacts, short service life of the battery, leakage currents etc. The enclosed drawing shows the functioning of the compressed air starter. Fig. 1: compressed air flows out of the cylinder through the line (1), drives the turbine, which drives the engine flywheel (10) by way of the gears shown. At the same time compressed air through the line (2) forces the piston (4) upwards against the spring (5) so that used compressed air can escape through the aperture (6). Fig. 2: after starting, the spring (5) forces the piston (4) back down. The engine now drives the turbine. Air is drawn in through the apertures (7), compressed and forced through the bore (8) and line (9) into the compressed air cylinder. The starter system could be especially suitable for engines of heavy land-based vehicles and for ship's engines of a certain size. <IMAGE>

Abstract: The invention relates to a latticework which is assembled from prefabricated beams, can be propped up at the individual points and also along the lines, and can be used as a structure lying on the plane or on a slightly curved surface. The latticework comprises two beam groups which rest perpendicularly on each other. Said groups are connected to each other by means of flexible pins - which are preferably produced from stainless steel - to be precise such that, within the latticework, the ends of the beams, expediently of the same length, are connected to the centre of the side surface of the beams resting perpendicularly thereon, and vice versa. On the border of the lattice work, use is also made of shorter beams which are connected by means of the through-passage bore, located perpendicularly on the longitudinal axis, or the blind bore, running parallel to the longitudinal axis, and the pins located in the bores and preferably produced from stainless steel. The bores formed in the beams are filled with a flexible material.

Title: Method of producing semiconductor devices
Inventor: BIERHENKE HARTWIG DIPL ING
IPC: H01J37/30
Filed: 1981-09-29
Abstract: In a method of producing structures on the surface of semiconductor wafers by means of moving electron beams, the electron beam supplied by a high-current electron source is shaped by means of a condenser and then split into at least two mutually equal sub-beams on its path to the workpiece (8) by electrooptical means (2). The sub-beams thereby obtained are focused in the same way and caused to act on different points on the surface of the workpiece (8). However, the method can also be performed with a treatment beam consisting of mutually identical ions. Compared with the "single-beam electron-beam pattern generators" of the prior art for the treatment of semiconductor surfaces, a marked shortening of the treatment time of the semiconductor wafer is achieved, while compared with the "multibeam electron-beam pattern generators", the step proposed by the invention achieves an improved utilisation of the total current carried by the system. <IMAGE>
