Title: Hybrid solar heat collection system - combining thermal absorption with photovoltaic effect
Inventor: KLEINWAECHTER JOHANN PROF DR I
IPC: F24S23/00
Filed: 1978-11-02
Abstract: Photovaltaic solar cells convert only 15% of the incident solar energy into electric power so that the remainder which is converted into sensible heat has to be recovered by a circulating fluid system, turning it into hybrid system. The proposed solar cell is therefore located at the bottom of a heat insulated box which is traversed by a coolant of high transmittivity for the solar spectrum producing a photoeffect. Water, for example, has an excellent transparency for wavelengths of 0.4 to 0.9 mu but acts as a black absorber for wavelengths above 1.2 mu. A suitable gaseous fluid would be CO2. Preferred design, a reflector focuses the solar radiation on a hollow cone with mirror walls which in turn concentrate the radiation at an optimum aperture angle on the small solar cell. Polypropylene foil is pref. as a transparent cover. This makes the optimum use of wavelengths which do not contribute to the photovoltaic effect, before they reach the cell.

Patent DE-2933116-A1 (DE)
Inventor: WILLAM FRANZ
IPC: G01P5/10
Filed: 1979-08-16
Abstract: In a device for measuring the breath volume of patients, a pair of temperature sensitive sensors are arranged in a tube-like housing of a respiration conduit of a respirator. The sensors are spaced from one another in flow direction and an air resistance member is arranged between them in such way that at least in one of the opposite air flow directions one of the sensors is in a position sheltered from the air flow by the air resistance member. Both of the sensors are connected with electronic circuits respectively and a current supply for holding the temperatures of the sensors on constant high levels. A calorimeter unit is connected to the circuits measuring the current supply necessary to compensate the temperature decrease of the sensors caused by the cool respiration flow. The air throughput is calculated in dependence on the measured current supply. Because in a predetermined flow direction the leeward sensor with respect to the air resistance member needs a lower current supply than the upstream sensor the calculating device provides different outputs for the pair of sensors whereby the flow direction can be determined and only the expiration air volume is indicated.

Title: Practise target for fire-arms - has shot position indicator with metal rings stacked to form cone and short circuited by impact of shot
Inventor: SCHAEFERS THEO
IPC: F41J5/04
Filed: 1979-09-03
Abstract: The target for a small arms firing range consists of a number of hardened metal rings of different dia. stocked to form a cone. The outer edge of each ring is bevelled at the same angle as the cone and each slightly overlaps the larger ring beneath it. Viewed along the axis of the cone, they appear as concentric rings, similar to a target card. The rings are separated by insulators and each is connected to an electronic indicator. When a shot strikes the target, it momentarily connects two rings together. This triggers a circuit to indicate on a display which ring has been hit. The shot is then deflected down the cone and strikes one of a ring of eight segments, momentarily connecting it to an outer ring. This triggers another circuit to light one of a ring of eight LEDs, indicating the direction of the shot from the centre.

A moving contact wire (10) is moved by a bar (11) on the key between two contacts (12,13). The time taken to move between the two contacts determines the sound level and this is fixed by how quickly the key moves in response to force (P) and the mass (7) and coil spring (8) dynamics.
Patent DE-3002783-A1 (DE)
Title: Cylindrical, magnetostrictive detector with piezoelectric plate - converting change in magnetisation in core of Wiegand wire to high voltage
Inventor: GROBE WOLFGANG DIPL ING
IPC: H01L41/12
Filed: 1980-01-26
Abstract: The detector consists of a cylindrical ferromagnetic inhomogeneous wire (Wiegand wire) exposed to an external magnetic field. At least part of the surface of the wire is fixed to a piezoelectric crystal plate. The core of the Wiegand wire reverses its direction of magnetisation when the external magnetic field is applied or removed. The change in magnetisation causes magnetostriction in the wire, which is transferred to the piezoelectric plate thereby causing a voltage to appear across the plate. This voltage is high compared to that obtained from detectors using coils to respond to the change in magnetisation in a Wiegand wire. Costs are also reduced.

Title: Detecting faults in underground pipe corrosion protection layers - uses potential measured w.r.t. reference electrode following calibration measurement
Inventor: HEIM GERHARD DR ING
IPC: G01N27/20
Filed: 1980-03-06
Abstract: The appts. is used for detecting fault locations in corrosion protection coatings of earth covered cast or steel pipes and can be employed with each type of coating and pipe material. The potential of a properly coated pipe is determined in a test sequence w.r.t. a reference electrode. The potential of the covered, electrically insulated pipe is then measured w.r.t. the same reference electrode and compared with the previously determined value. For pipes with a glass fibre reinforced concrete coating with additional organic sealing material a potential more negative than -500 mV w.r.t. a copper sulphate electrode would indicate the presence of a fault. For pipes with a purely organic coating on a plastic base a potential other than 0 mV would be interpreted at indicating a defect.

Title: Seat belt safety system for motor vehicle - prevents engagement of gears other than first and reverse by blocking travel of lever if belt is not used
Inventor: REDMOND BENJAMIN
IPC: B60R22/48
Filed: 1980-04-12
Abstract: In the seat belt safety for motor vehicles the belts are elements of a common electrical circuit operative to control the drive system of the vehicle, but independent from the operation of the vehicle's engine. An unbuckled seat belt in any occupied seat of the vehicle will automatically prevent putting the vehicle in motion, except in reverse gear or the lowest forward gear. A button completes an electrical circuit for simultaneously removing the detent from its interlocked position with the gearshift lever and activating a second solenoid associated with a second detent which projects into the normal path of travel of the gearshift lever, preventing it from being shifted into any forward gear higher than the lowest such gear.
