Patent DE-2759304-A1 (DE)
Title: Multiple digit signal transmission circuit - uses pulses of two kinds and second kind pulses may have effect on first pulses
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q3/00
Filed: 1977-12-16
Abstract: The signals are, e.g., tens and units criteria transmitted on the base of pulse position modulation, for STD systems. Signals are transmitted simultaneously over only one wire. Pulses of a first kind which must become effective at a specified time, or for marking of a specified selector output, are either not affected at the specified time by pulses of a second kind, applied to the transmission wire through marker elements, or voltage or current of pulses of the first kind are so affected, that they have no effect on the evaluation element. The second kind pulses are marked by a gap or by pulsewise connection of resistors of voltages.

Title: Operating device for magnetically controlled switch - with contacts mounted on case wall and operated by magnet placed near them
Inventor: WENTE WALTER DIPL ING
IPC: H01H36/00
Filed: 1978-02-06

Patent DE-2833104-A1 (DE)
Title: Damping device for balance beam oscillations - has cylinder with piston, filled with damping medium, and bimetal element in by=pass channel
Inventor: SCHWARZ JOSEF
IPC: G01G23/08
Filed: 1978-07-28
Abstract: A vessel is filled with a damping medium into which a piston connected to the beam is immersed. A bimetal element compensates changes of the liquid viscosity due to temp. changes by changing the clear cross-section for the damping medium flow. The vessel (5) has a bypass channel (8) between its bottom and top parts. The bimetal element (11) changes the bypass channel cross-section, and when the flow velocity in the channel is high, it springily reduces the channel cross-section.
Patent DE-2839064-A1 (DE)
Title: Emulsifier for water injection into fuel oil - having opposed jets for water and oil in closed box which leads to storage before cavitation pump
Inventor: SOERENSEN FLEMMING
IPC: F23K5/12
Filed: 1978-09-07
Abstract: Oil/water emulsions are produced by simultaneously injecting both components into a box through atomising sprays and then feeding the mixture to a cavitation pump. The two series of nozzles are mounted opposite to each other. The emulsion coming from the mixer box is held in a vessel, round which it is circulated by the cavitation pump. This can be reciprocating or multi-stage rotary. Used for creating oil water emulsions for use as fuel. The injection of water into fuel supplies reduces coking in burners. Efficient emulsification means less water needed and more efficient combustion with less coking.

Title: Exposure control for SLR system camera - has circuit controlling setting signal so that same results are produced for same conditions irrespective of max. aperture of lens fitted
Inventor: WATANABE SAKUJI
IPC: G03B7/081
Filed: 1978-12-27
Abstract: The full aperture TTL metering for the SLR system camera has a special control circuit which maintains the shutter speed setting when the lens is changed for a different type having a different max. aperture. This is realised by using a main control signal duly regulated for each lens type. The system ensures that scenes with similar exposure factors provide the same automatic set shutter speed, irrespective of the lens fitted. As the shutter release button is pressed the power source switch (SM) is closed to supply the whole circuit from the camera battery (E1). A photo-diode (PD) receives the light through the lens. Its output signal is amplified by an operational amplifier (OP1) and logarithmically suppressed by a diode.

Title: Folding venetian blind turning mechanism coupling - has opposite offset serrated pawls on roller and cogwheel on spindle
Inventor: AMMAZZALORSO MARIO
IPC: E06B9/322
Filed: 1979-01-08
Abstract: Draw organs, wound up on drums, are seated on a setting and drawing spindle, and borne by ladder guides led across turning rollers on the spindle, in the concertina-folding slatted venetian blind. A coupling provides firm connection between spindle and roller, within a set slat swivelling range, and opens on reaching an end release unit. The coupling is a pawl ratchet. This comprises two opposite-way, radially sliding toothed pawls offset through 180 deg. in the roller together with a cogwheel on the spindle. The release unit, guides the locking pawl concerned out of engagement with the cogwheel. This provides reliable form-locking coupling, while still being accommodated inside the roller.

Title: Geiger radiation dosimeter with pre-calculation - operates with input values and considers preset time periods under control of pushbutton
Inventor: HAUBER SIEGFRIED
IPC: G01T1/18
Filed: 1979-03-01
Abstract: The dosimeter is intended for emergency cases, enabling the radiation detection to be carried out by unskilled persons. The handling of the dosimeter is simple and unambiguous results are obtained in the expected range of radiation doses. The radiation dose power is precalculated in relation to preset time, thus giving a high result for a greater time period. The dosimeter is controlled by the depression of one of three push-buttons and the response is given by an illuminated display, in which a green light equals "yes" and red light "no". a specified tube for beta and gamma radiation is used as a counter. Each particle penetrating the tube triggers a discharge pulse. All the latter are amplified for counter processing. The final stage is an evaluation electronic system staring from zero.
