Patent DE-2715494-A1 (DE)
Title: Rotating mirror for optically scanning flat surface at constant speed - uses lever and pulley system to provide mechanical analogue of optical system linearising scan speed
Inventor: SHOGREN DAVID KIRK
IPC: G03B27/52
Filed: 1977-04-06
Abstract: In the flat platen, rotating mirror scanning system the angular velocity of the rotating mirror is continually varied from end to middle to end of scan to effect a constant speed of scan across the platen surface. This is achieved by providing a mirror drive arrangement which is the mechanical analog of the optical geometry. Conjugate distance changes inherent in the flat platen scanning are compensated by a stationary 'half-lens', adjacent to the rotating mirror. The drive may be provided for the mirror by a belt linking the mirror wheel (30) and a drive wheel (32). The wheel (32) is moved by a driver (26) moving a lever (24) attached to the wheel. Linear constant motion of the driver provides constant velocity scanning.

Title: Mine gallery hole drilling guide - is attached to face for first hole, then inserted in hole for further holes
Inventor: HASENCLEVER JUERGEN
IPC: E21B19/24
Filed: 1977-04-14
Abstract: The appts. for drilling holes in a mine gallery wall, is used to ensure the accurate alignment of a pilot hole at an acute angle to the vertical face. It is then used in a different position for guiding the drill for making further holes at different angles. A tube ( ) with a pointed end and a semicircular strap (2) at the other end is first attached vertically to the face (B) to be drilled. An angle bracket (7) is then attached to it at a suitable height. This act as a spacer against the upper part of the drill. The strap (2) at the bottom then guides the drill top. After drilling the pilot hole (13), the tube (1) is then inserted in the hole with the strap at the top. This then guides the drill at a required angle for drilling further holes (14, 15, 16).

Title: Water scrubber for exhaust gas streams - which contain hazardous materials has rotating tubular paddles inside housing with internal baffles to divide it into compartments
Inventor: STAEHLER THEO
IPC: C02F3/08
Filed: 1977-05-14
Abstract: Contaminants present in industrial exhaust gases are scrubbed out in a water filled scrubber. This has a closed vessel with an inlet at one end and an outlet at the other. It has a series of internal partitions which extend from the top below the water level, forming a series of compartments. A shaft down the centre of the housing has a series of paddles located around it which are rotated through the liquid and gas spaces. These are hollow cylindrical devices with holes around one side. attached to the supports for these are baffles which extend to the edge of the adjoining partition wall. The elements collect a charge of gas and allow it to bubble up through the water, the baffles deflecting it into the adjoining compartment. For use in removing offensive materials from exhaust gas streams. Provides a straightforward relatively cheap system which is very effective, giving an outlet gas stream free of offensive materials.

Title: Single channel direction finder - processes received signals so that they contain either phase differences, of azimuth and angle of elevation
Inventor: BAUR KARL PROF DR
IPC: G01S3/48
Filed: 1977-05-26
Abstract: The direction finder has a switch through which voltages from an antenna system are applied in quick succession to a single channel receiver. An evaluation device uses phase difference of received voltages for determination of the direction of incidence. A scanning device is inserted between the receiver and the evaluation device. Switching and scanning sequences of the switch and the scanning device depend on the antenna system used, and are such, that the evaluation device generates direction finding functions by multiplication, division, squaring or square root extraction, depending on the antenna system. They contain either the phase differences necessary for the direction of incidence determination, or the azimuth and angle of elevation themselves.

Title: Splint plate for rib fractures - is formed of spring steel with profiled surface which grips rib but allows flexing during breathing
Inventor: LABITZKE REINER DR
IPC: A61B17/80
Filed: 1977-08-17
Abstract: A plate for use in the treatment of multiple rib fractures is attachable to the ribs without the use of screws and brings the rib ends into registry. The plate is made of implantable spring steel and has a profiled surface that grips the ribs while allowing the rib cage to flex during breathing.

Patent DE-2826058-A1 (DE)
Inventor: MUTTI WERNER H DIPL ING
IPC: F24J3/00
Filed: 1978-06-14
Abstract: Method and apparatus for storing of heat by use of the heat of fusion or crystallization of a liquid-solid storage medium. A conventional crystallization roller rotates with its circumference partially immersed in the melted storage medium. Heat receiving liquid circulated through the drum to a point of use receives heat from melted storage medium in contact with the drum, whereby such storage medium solidifies on the surface of the drum. The drum rotates the solidified storage medium past a fixed scraper which transfers the solid storage medium to a heat exchanger. Heat supplying liquid circulating through the heat exchanger imparts its heat to, and melts, the scraped-off storage medium which returns to the storage medium reservoir and brings with it the heat obtained from the heat supplying liquid.
