Patent DE-2912206-A1 (DE)
Title: Solar trays for air heating - are in line to form closed heating channel, with hot air discharge branches at first tray inlet and last tray outlet
Inventor: WIENEKE FRANZ PROF DR ING
IPC: E04D13/18
Filed: 1979-03-28
Abstract: The row arrangement of the air heating trays is such that the air heating path is contained inside the trays and enclosed channels. The hot air branches are connected directly to the inlet of the first tray and to the outlet of the last one. Thus air flows completely within a closed system in which air is subjected to a cyclic process of heating and heat discharge. Pref. each tray has an absorption surface with a roughness and/or selective coating so as to increase the radiation absorption and reduce the heat emission. The tray side facing the radiation may have grooves covered with an absorption foil, enclosing air between itself and the tray base. The tray underside may be coated with an insulant. The trays may be laid on roof slabs and insulating plates may be fitted in between. A transverse channel between the trays and insulating plates may form an exhaust channel for hot air.

Title: Frame saw blade hinge spacer - has faces fitting against two blades and is offset from second holder plate
Inventor: ROTH LUDWIG
IPC: B27B3/38
Filed: 1979-04-14
Abstract: A series of saw blades with spacers are clamped in the frame with hinge shafts supported at one end on the frame, and other end bearing an attachment providing form-locking connection in the tension direction, with a lug swivelling on the shaft. Spacers (26) to be clamped between blades (23) are held at the end of one of the two plates (36) forming the hinges attachments (32) away from the shaft. One face (37) fits against the inserted blade and the other (38) against the next blade. They are offset lengthways from the second plate, leaving a 5mm gap between plate and spacer. This allows spacers to be immediately fitted with frame saw hinges.

Title: Laser Doppler radar with heterodyne reception - has receiver band filter with Doppler width matching natural environments and frequency corresponding to stationary target
Inventor: SEPP GUNTHER DIPL PHYS DR RER
IPC: G01S17/50
Filed: 1979-05-05
Abstract: The laser radar is intended for detecting the movement of distant targets in front of the terrain background. The signals for a scanning control device are derised from the Doppler shift of the received signals. A first image scanning is carried out via a receiver band filter with a Doppler width, matching the natural environments, as well as a mean frequency corresponding to stationary targets. The image gaps, resulting from moving targets, are measured and evaluated by a second image scanning. Pref. image points are recognised without a laser radar echo and are indentified. During the second image scanning only a partial section is measured and evaluated, this section possibly containing a locally maximum reflectivity. In order to detect the velocity of the moving target, the mean frequency of the bank filters may be shifted over the entire Doppler range to be evaluated for each scanned image point during the second scanning.

Title: Vehicle navigation gyroscope correction - is made when vehicle is at rest using north-seeking gyroscope and frame relative angle nulling
Inventor: AUER WERNER DR ING
IPC: G01C19/34
Filed: 1979-10-20
Abstract: A gyroscope unit for a vehicle has a vertically supported navigation gyroscope with a north-seeking gyroscope enabling correction of the navigation gyroscope indication when the vehicle is at rest. The navigation gyroscope is rotated about its vertical axis (7) by resetting devices engaging the horizontally mounted frame. The north reference is transferred to the navigation gyroscope without gimbal errors even when the vehicle has an inclined attitude. This is achieved economically and without addition time. Measurement instruments (10) determine the deviation from 90 degrees of the angle between the planes of both gyroscope frames (2,4). The reset devices are controlled to correct the navigation gyroscope indication using the north-seeking gyroscope and according to the measured angular deviation. The deviation is nulled and the new navigation gyroscope direction determined by the north-seeking gyroscope.
