Patent DE-2532873-A1 (DE)
Title: Highly heat insulating vapour diffusant masonry - comprises vertically holed block with light insulation filling blown or bonded in
Inventor: SPEIDEL HANS-HERMANN DIPL ING
IPC: E04C1/41
Filed: 1975-07-23
Abstract: The purpose of the process is to erect masonry walling which combines a high degree of rigidity with highly effective heat insulation and unlimited water vapour diffusion capacity. This is achieved by using building blocks with vertical holes in them, the holes being completely or partially filled with insulating material which is heaped into them. This material may be of the foamed type or fibrous mineral substances. It may be blown in, or bonded in with adhesives. It may be endowed with a constantly greater diffusion capacity than the material in the masonry. The type of wall required can be easily erected using standard and commonly available raw materials.

Title: Cattle truck with raising floor - using fixed rotating vertical spindles threaded to captive nuts at corners of floor
Inventor: BANNAS PETER
IPC: B60P3/04
Filed: 1975-07-31
Abstract: The cattle truck is fitted with a lifting floor whose corners are provided with captive nuts threaded on vertical shafts. The shafts are rotated by servo motors under the floor of the vehicle to raise and lower the lifting floor. The system enables the floor to be raised the full extent inside the vehicle to provide maximum headroom for cleaning, etc. The threaded shafts are simpler to operate than individual hydraulic rams and occupy less space. A single servo motor can be provided, linked to the other shafts by a belt drive. More than one floor can be fitted, using special nuts which can uncouple from the shafts.
Patent DE-2536413-A1 (DE)
Title: Conduction state monitor for high voltage rectifier - is used to initiate turn or if insufficient elements reach blocking state
Inventor: MATEJKA JAROSLAV DIPL ING
IPC: H02H7/12
Filed: 1975-08-13
Abstract: In rectifiers for high voltage with many thyristor elements in series the effect of scatter in turn-off times may occasionally result in an inadequate number being in the off state when voltage is reapplied. A circuit is needed to rapidly detect this condition and retrigger all series devices to prevent damage. Monitoring elements from the thyristors provide inputs (e1-en) to a first OR-gate (1) whose output (b) passes both directly to a second OR-gate (4) and to an inverter (2) in series with a monostable multivibrator (3) with a time delay just long enough to incorporate the full scatter of late turn off signals. The multivibrator is triggered by the first pulse and remains on until the pulses arrive in quick succession.

Title: Sound film camera with photoelectric transducer - uses infrared radiation for view finding in poor visibility
Inventor: STEMME OTTO DIPL PHYS DR
IPC: G03B31/02
Filed: 1975-09-18
Abstract: The sound film camera comprises a photoelectric transducer activated by sound-modulated infra-red rays passing through the objective, but disposed in a light path branching off from that of the objective. The transducer is connected to a threshold circuit with adjustable threshold, which controls either an indicator visible in the finder or an acoustic indicator. For spot measurement of the infra-red beam, either the transducer is of small spatial construction compared with the picture area, or it is used with stops. The size and position of the spot in the finder relative to the picture area are similarly characterised. Pref. the sound-modulated infra-red rays are reflected off by a mirror or prism separating the view-finder light rays from the infra-red rays.

IPC: F16L27/08
Filed: 1975-10-01
Abstract: Connection between relatively rotatable pipes comprises a rolling element bearing (6) between radially inner and outer parts connected to the respective pipes, and a seal (4) arranged between the parts. the seal comprises a disc secured to the one part and having a narrow annular portion bearing resiliently onto an axial face of the other part.

Title: AC voltage control unit - with tappings of transformer primary winding switched by electronic switch at current zero crossings
Inventor: BECK ALFONS DIPL ING
IPC: G05F1/20
Filed: 1976-06-04
Abstract: The control is carried out by varying an output transformer transformation ratio, a function of the a. c. voltage amplitude. An electronic switch (ES) combined in individual groups is connected to the transformer primary winding provided with several tappings. A. C. voltage to be controlled is applied to the switch (ES) input controlled by an ignition distributor (ZV) operating by the BCD code. The ignition distributor (ZV) receives its commands from a command circuit (KS) which delivers a frequency proportional to the absolute value of voltage deviation, and a binary signal for positive and negative voltage deviations from nominal value. The ignition distributor is in addition controlled by a zero current detector (NS), so that ignition of the electronic switch takes place only at, or close to the current zero crossing.

Title: Ultra short wave stereo broadcast signal receiver - has signal demodulated and transposed to ultra short wave band either directly or after modulation on carrier
Inventor: LOOK JUERGEN
IPC: H04B1/16
Filed: 1976-10-30
Abstract: The receiver has at least one input and one output frequency changer, and the filtered out channel signals are prepared at the i.f. stage. All channel signals are brought to a common constant level. The i.f. signal, or at least a part of it is demodulated in an f.m. demodulator (9) and the stereo multiplex signal is applied to a filter (13) (low-pass filter and/or absorber circuit), so that the sum signal (L+R, 0-15 kHZ) is transmitted and/or pilot signal suppressed. If signal-to-noise ratio (input signal) is insufficient for stereo reception, the signal selected by the filter (13) is modulated on a carrier and transposed to a channel in the ultra short-wave sound broadcasting band. If the signal to-noise ratio is sufficient, either the non-selected stereo multiplex signal, or the modulated stereo h.f. signal in the i.f. stage is transposed to a channel of the ultra short wave sound broadcasting band.

Title: Solar heat collector control device - adjusts orientation of reflectors according to position of sun to maximise collection efficiency
Inventor: SCHLUETER PETER
IPC: G01S3/786
Filed: 1977-03-17
Abstract: The solar heat reflectors can be automatically adjusted angularly in such a way that the solar rays always impinge on the reflectors at an angle of 90 degrees so that the best collection efficiency is ensured. A cylinder contg. three radial bores at slight angles from each other, each terminating in a photodiode, is revolved by a reversible stepper motor in such a way that an outer photodiode receive max. intensity, and an electronic logic circuit causes the motor to turn the cylinder until the central diode receives the max. intensity. The motor is then stopped. An UP-DOWN counter records the necessary steps and causes the stepper motor controlling the angle of the reflectors to move the reflectors through a corresp. angle via another logic circuit.
