Title: Motor vehicle jack - has non-pivoting foot on column rolling over from setting sole on lifting
Inventor: DINSING KARL-AUGUST
IPC: B66F3/12
Filed: 1974-06-07
Abstract: The jack has a column with a supporting foot, on which a supporting arm pivots on a spindle not adjustable in the vertical direction. At the free end of this arm is a load supporting head engaging with the vehicle floor. A screwed spindle or other suitable mechanism is suspended from the column head and engages with the arm between head and spindle. The supporting foot (12) does not pivot on the column (13), and as the jack is raised rolls over onto its supporting sole (19) from the setting sole (23) originally bearing on the ground. The jack can be arranged so that it does not tip when the setting sole is on the ground, and foot and column can be integral.

Title: Electroacoustical system volume control - uses total surrounding and loudspeaker noise and sound signal which are connected in opposition
Inventor: NIPPOLD HELMUT
IPC: H03G3/32
Filed: 1974-07-26
Abstract: The difference signal resulting from connecting the signals in opposition is used for the system volume control, so that the volume increases or decreases in accordance with the difference signal; the noise signal and sound signal are rectified before connection in opposition; the signal corresponding to the total level is subjected to a physiological correction and the sound signal is corrected accordingly; the difference signal is filtered in a low-pass filter. A low frequency amplifier is connected to the loudspeakers, and there are feedback circuits. Feedback from the microphone to the loudspeakers is neutralised, to prevent howl and oscillations.

Title: Self supporting solar energy absorption panel - is constructed of glass sheets fitting together without a surrounding frame
Inventor: SCHOELL GUENTER PROF DR ING
IPC: F24J2/50
Filed: 1974-08-14
Abstract: The panel is assembled from a number of sheets of silica glass or material with similar radiation transmission properties. The sheets are all identical to each other. Each sheet consists of a main plane surface (1) with two edges (2, 3) turned up and down respectively to make inclined flaps. The turned down flap (3) of one sheet fits over the turned up flap (2) of the next sheet so that a long line of sheets can be attached together and hold each other in place without having to be fitted into a peripheral frame. This avoids shadows cast by the frame and also cheapens the construction. The edge of the upturned flap (2) has a rubber or plastic strip (9) along it to form a seal between successive sheets.

Title: Lacquer powder coating compsns. - prepd. by freeze drying mixt. of pigment, polymer binder and solvent
Inventor: FABIAN WOLFGANG DIPL CHEM DR
IPC: C09D5/03
Filed: 1974-12-20
Abstract: Powder coatings are prepd. by freezing a mixt. of pigment, polymer binder and solvent, removal of the solvent by sublimation under reduced press. and pulverisation of the residue. Used for application to metal substrates by sintering or electrostatic spraying processes. Powder coatings made by melt extrusion processes cannot be subsequently pigmented so colour range is limited. Removal of solvent from pigmented pastes by e.g. azeotrope distn. after H2O addn. can alter compsn. of final prod. Freeze drying avoids these difficulties.

Patent DE-2504273-A1 (DE)
Title: Epibase transistor with mesa structure - with full face diffusion of emitter region in epitaxial base region on substrate
Inventor: KARGEL HANS-JUERGEN
IPC: H01L21/308
Filed: 1975-02-01
Abstract: An epibase transistor is produced by diffusing the emitter region over the full face in the base region. A covering insulating layer receives diffusion windows for contacting the base region. Impurities are diffused into the base region through these windows and through the emitter zone. The emitter zone is contacted through windows in the insulating layer. This procedure saves masking and diffusion operations. The high film resistance of the emitter region stabilises the emission current; the emitter efficiency can be set to an optimum by choosing an appropriate impurity concn. and impurity profile in the emitter region.
