Title: Prodn. of tomographic pictures without blurred shadows - uses set of pictures taken from different directions to form correction picture
Inventor: MEYER-EBRECHT DIETRICH DR
IPC: H05G1/64
Filed: 1975-04-18
Abstract: The tomographic pictures for different depths are produced by superposition of shifted primary pictures. Tomographic pictures so obtained are shifted and superposed, and the superposed picture is used for production of a correction picture. The method consists of the following steps: tomographic pictures are shifted w.r.t. each other in accordance with the geometric conditions during a primary picture talking, and superposed on each otherso obtained and the corresponding primary picture are subtracted from each other in order to obtain a correction picture primary pictureon the tomographic picture with the same shift and the same, or slightly reduced, relative amplitude as the corresponding primary picture.

Title: Remote adjustment for external driving mirror - with hollow rotating shaft and concentric push rod for tilt
Inventor: FEHR HORST
IPC: B60R1/064
Filed: 1975-07-01
Abstract: The external driving mirror (19) is mounted at one end of a hollow support tube (5) on a pivot axis (18).

Title: Increasing the abrasion resistance of steel parts - by immersion in a mixt. of molybdenum disulphide, sulphuric acid and glycerol
Inventor: VERCHOVYCH PETR MICHAJLOVITSCH
IPC: C23C12/02
Filed: 1975-07-09
Abstract: An abrasion resistance of steel surfaces is increased by (a) forming a mixt. contg. 20-80 g MoS2 and 1-5g H2SO4 per litre of glycerol, (b) heating the mixt. to 190-230 degrees C, and immersing the steel in the mixt. for 3-7 hrs. in the presence of brass.

Title: Tidal flow controlled continuous water drawing installation - has float opening or closing three sluices by own weight
Inventor: SOLEWSKI ALBERT
IPC: F03B13/26
Filed: 1976-02-16
Abstract: Tide controlled, continuously working water drawing installation has a reservoir (b) which is filled by the flood tide (a). Three sluices in the installation (a1, gi, hi) are maintained closed. Three small basins (c1, c2, c3), extending from wall to wall, are also filled with water. Water is then impelled by three valves (c13, c14, c15) into three drawing basins (c4, c5, c6) which rest on rollers (c10, c11, c12) on superstructure (j1, j2, j3) slide rails (j3, j4, j5). One sluice (b1) is firstly manually opened. Water flows from the reservoir (b) into the main basins (c1, c2, c3) and presses a floating component (j) up to the superstructure (j1, j2, j3) at whose head ends are the rails (j3, j4, j5). The drawing basins (c4, c5, c6) slide with their rollers (c10, c11, c12) along the rails (j3, h4, j5), and the drawing basins, filled with water from the three main basins (c1, c2, c3), are pressed outwards. The floating component (j) is able, by reason by its own weight, to open or close the sluices (b1, b1, h1).

Title: Asynchronous delta modulator with run length coder - has buffer memory in feedback circuit between comparator and predictor
Inventor: MATT HANS JUERGEN DIPL ING
IPC: H03M3/02
Filed: 1976-03-03
Abstract: The asynchronous delta modulator n1) is used for adaptive analog/digital conversion. It performs the conversion by comparing the analog input with a predictor output and by using the result of the comparison to decide the polarity of the output. The comparator output feeds a run-length coder and a buffer memory. The run-length coder is located in the delta demodulator feedback circuit between the comparator output and the input of the predictor. The delta modulator output signals are thereby converted into a synchronous continuous data sequence.

Title: Air cooled rotor in generator - is lifted by air pressure produced by propeller on rotor
Inventor: TIETZSCH KARLHEINZ DR
IPC: F03G7/04
Filed: 1976-09-06
Abstract: A generator is surrounded by a shell which is open at the top and closed at the bottom and has an air discharge valve. A rotor is mounted vertically within it. The bottom end of the rotor shaft is supported on a ball bearing. A disc with inclined blades cut into it, is rigidly attached to the rotor immediately above the bottom bearing. A plain disc not fixed to the rotor above the tope of the rotor limits the vertical lift of the rotor. The propeller action of the bottom disc lifts the rotor as it revolves and the resulting air pressure is released through the air discharge valve. The flow of air which this causes produces the necessary cooling.
