Title: Roof heat recovery circuit - combines heat through glass tiles with heat collected under eaves in hot water and heat pump circuit
Inventor: LUDWIG ERICH DIPL ING
IPC: F24S10/30
Filed: 1980-01-23
Abstract: The method of obtaining heat from the roof of a building uses both the heat of the sun, and also hot air rising up the walls, collected at the overhang of the roof. Instead of tiles, the roof carries glass panes, flanged along their edges, so as to form air circulating channels underneath. Air is also collected from the space behind the gutter (4) through holes (9) between the roof rafters (1). The combined flows (10) return through similar holes at the highest point of the roof to pass to a heat exchanger with a water circulating coil. This is connected to a hot water tank, and in the supply line to the tank is a temperature sensor and control valve. This controls the flow so that under a certain temperature, the flow is passed to a heat pump which also has the tank in its secondary circuit.

Title: Multilayer circuit board alignment system - uses bored holes and solder bosses as reference marks
Inventor: SCHEU ERICH KARL
IPC: H05K3/00
Filed: 1980-08-16
Abstract: Printed circuit boards that are stacked and compacted into multi-layer circuit boards require to be accurately aligned so that displacements of the tracks and solder bosses cannot occur. This can be overcome by applying a solder boss to each circuit board as a marker, over or below which, there are no solder bosses or tracks respectively, on the other circuit boards used in the stack. A reference hole is also made in the board and passed through the boss. When the translucent multi-layer board is held up against a strong light source, the positions of the solder bosses relative to the bored holes can be clearly seen. By producing these bored holes on a digitally controlled boring machine, all the holes will have an exact relative position to one another. The displacement of each individual P.C.B. to the hole reference diagram can then be seen immediately.

Title: Pump unit without stuffing box
Inventor: WUNDERLICH ERHARD ING GRAD
IPC: F04C15/00
Filed: 1981-02-21
Abstract: A pump unit without a stuffing box and consisting of a drive motor and a screw displacement pump, in which the motor shaft and the pump drive spindle are connected in series and are preferably made in one piece, is to be refined in such a way that it can be used for delivering aggressive, toxic, radioactively contaminated and other hazardous liquids as well as of, at high delivery pressures, low-viscosity and poorly lubricating media. This object is essentially achieved by the drive motor being a canned motor whose rotor cavity, by virtue of being connected to the suction chamber, is relieved of the delivery pressure of the screw displacement pump. A floating axial thrust compensation and the vertical arrangement of the motor pump shaft simplify the bearing arrangement.
