Title: Multi-element semiconductor device - having implanted semi-insulating zones separating (photodiode) elements
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L27/144
Filed: 1972-07-21
Abstract: In a semiconductor device with a no. of semiconductor elements (I), which are insulated from one another electrically, (I) are sepd. by semi-insulating zones (II) implanted in the body (III) of the semiconductor. The technique is esp. useful in the prodn. of "lighting arrays" of a no. of independently controllable photodiodes. Mfr. is simplified, since the need to etch grooves in (III) is eliminated.

Title: Drying wet goods, esp. chopped sugar beet - using flue gases, controlled burner temp makes heat reducing chamber unnecessary
Inventor: PAULI BALDUIN DR ING
IPC: F26B23/02
Filed: 1974-04-25
Abstract: An arrangement for drying wet goods, esp. chopped sugar beet, utilising the heat in th flue gases from boiler and other installations, has a burner positioned in the end wall of the combustion chamber, fed by fresh air and flue gases through a mixing duct with a built-in fan, and a fuel feed pipe. The combustion chamber has a cooling jacket through which fresh air is drawn, and the drying zone, esp. the drying drum may be joined directly on to the combustion chamber. Or between the two, there may be a mixing chamber into which some of the flue gas may be diverted for regulating the temp. In existing installations some flue gas can be fed into the mixing zone, otherwise the proportions of fresh air and flue gas can be adjusted to give the required temp. at the burner outlet. Savings of fuel are important and less heat, dirt and acid pollutants pass into the atmosphere.

Title: Spine-relaxing health pillow for prone position - is horse-shoe shaped with ventilation holes affording optimum relaxation of body muscles
Inventor: FREUND ERICH
IPC: A47G9/10
Filed: 1974-06-24
Abstract: The pillow is made resilient in a horseshoe shape and is filled with foam and/or air.

Patent DE-2432477-A1 (DE)
Title: Closure flap for fluid flow duct - opened and closed by independently arranged mechanisms
Inventor: MARIALIGETI JOZSEF
IPC: F16K1/20
Filed: 1974-07-02
Abstract: The flap valve is opened by means of hydraulic pressure applied to the underside of a piston and cylinder arrangement, the piston being connected by a rod to the flap. A second hollow piston is arranged in a second hydraulic cylinder lying coaxially with the first and the rod passes through this second piston. On desiring to close the flap valve the first piston is caued to descend until a member attached to the rod closes the hollow piston which then acts as a brake by displacing hydraulic fluid through a throttling valve. In an alternative arrangement a pneumatic braking effect is achieved by a pneumatic cylinder attached to the flap valve co-operating with a fixed piston connected to the duct.
