Patent DE-2638895-A1 (DE)
Title: Integrated semiconductor circuit with photodiode - uses photodiode PN-junction and similar junction between zone and substrate for photocurrent generation
Inventor: BERCHTOLD KLAUS DR
IPC: H01L27/144
Filed: 1976-08-28
Abstract: The pn-junction of the photodiode in the bipolar integrated circuit lies in a semiconductor zone, adjacent the surface of the semiconductor substrate. This zone forms with the rest of the substrate a pn-junction. In addition to the photodiode pn-junction also this second pn-junction between the zone and substrate assists in the generation of a photocurrent. Preferably for this purpose the part of the zone-substrate pn-junction underneath the photodiode is used. The two pn-junctions may be connected in parallel, and they may be polarised in the blocking direction. The semiconductor zone is typically an epitaxial layer on the semiconductor substrate. An amplifier may also affect the photocurrent.

Title: Oil well bore hole bottom pump - is operated from top of bore by borehole gas
Inventor: KLAEGER JOSEPH HART
IPC: F04B47/14
Filed: 1976-09-29
Abstract: The pump has a working cylinder containing a reciprocating piston. A balance cylinder above the working cylinder contains a piston fixed to the piston rod of the working piston. The piston rod is extended downwards to work the pump at the bottom of the borehole. Gas rising from the borehole enters a five way valve which directs it to either the under or the upper side of the working piston. Gas released from the other side of the piston is discharged through the five way valve into the gas supply line. The five way valve piston is moved by pressure from relief valves in the top of the balance cylinder and bottom of the working cylinder.

Title: Steel pile system for retaining wall - uses U-section vertical piles to support horizontal planks
Inventor: BRAUN PETER DIPL ING
IPC: E02D17/04
Filed: 1976-11-12
Abstract: Vertical piles of U-shaped cross-section are set in drilled holes and have flanges (4) against which the horizontal wall planks, spanning between the piles, bear. The piles are reinforced with a thickening (7) which forms a toothed profile (9), against which pressure plates for the anchor rods bear. The anchor rods (15), which pass through holes (14) in the pile are grouted into oblique drilled holes in the ground and tensioned. Thee construction avoids the use of components which protrude from the front of the wall, and is simple to erect, requiring no welding.

Between the elements and the plaster/concrete layer is a further insulation layer of e.g. asbestos or felt material.
Patent DE-2709534-A1 (DE)
Title: Flow control valve for vehicle air conditioning - with pressure sensitive restriction to maintain even pressure in expansion coil
Inventor: ORTH CHARLES D
IPC: F16K31/68
Filed: 1977-03-04
Abstract: The vehicle air conditioning system has a compressor pump (C) driven off the engine and an expansion coil (E) for the cooling effect. A flow restriction valve controls the input pressure of the expansion coil to prevent damage. The valve monitors the relative values of the compressor output and a fixed pressure e.g. the inlet manifold pressure or atmospheric pressure. As the pressure increases so the flow to the expansion coil is reduced. The system allows the compressor to be continually driven off the engine, so that there are no sudden torque changes through uncoupling the drive. This leads to smoother transmission control and a simplified control system.

Title: Storage battery protective device against heavy discharge - has semiconductor switch which is polarised in blocking direction when end of discharge voltage is reached
IPC: G01R31/36
Filed: 1977-07-20
Abstract: When a specified lowest end of discharge voltage is reached, the load is disconnected from the battery by a switch controlled by a monitoring device. The switch is formed by at least one semiconductor component (T1) through which the battery (B) current flows both to the load (G) and to the monitoring device. When the end of discharge voltage is reached, the semiconductor is polarised in blocking direction and remains blocked without any power consumption. Preferably, the semiconductor forms part of the monitoring device, which has in addition a second semiconductor (T2) and two voltage dividers (R3, R4; R1, R2), dependent on output voltages of the two semiconductors. The blocking semiconductors polarity can be changed only by an external signal.

Title: Purification circuit for swimming pool water - includes active carbon filter improving UV radiator efficiency, reducing chlorine requirement
Inventor: RAUH LUDWIG
IPC: C02F1/32
Filed: 1977-12-07
Abstract: For the purification of the water of a swimming pool fitted with the usual mechanical filters, behind which, in the filtration circuit, there is a UV steriliser followed by a chlorine dispenser, an active carbon filter is also provided, behind the mechanical filter and in front of the UV radiator. The active carbon filter is dimensioned so small, that it allows through in considerable volume, free active chlorine whilst adsorbing all chlor-amines. To increase by inexpensive means the efficiency of the UV radiation sources very considerably, and to reduce the amount of chlorine required, so that skin irritation and the offensive smell are ruled out.

Patent DE-2804512-A1 (DE)
Title: Downhole measurements transmitted to surface - by converting transducer signals into digital drilling fluid pressure pulses
Inventor: WESTLAKE JOHN H
IPC: E21B47/18
Filed: 1978-02-02
Abstract: Appts. transmits information from down a bore-hole to the surface by producing pressure fluctuations in the drilling fluid. The appts. includes a transducer producing a voltage signal as a measure of some physical variable, e.g. temp., a system within a cavity to convert the signal into digital signal which is amplified and used to effect switching of a valve which allows drilling fluid to discharge from the conduit into the bore-hole annulus. This will produce a pressure drop at the outlet of the pump, and this digital variation is detected and converted back to analog.
