Patent DE-2456983-A1 (DE)
Title: Root crop row roller - consists of axle pipe and rods welded onto two rings
Inventor: HILGERS PETER
IPC: A01B29/04
Filed: 1974-12-03
Abstract: The roller breaks up clods of soil on the surface and consolidates the ground in front of the cultivator. The crop rows can be rolled and cultivated at the same time, without harming or destroying the plants. Several rollers can be fitted behind each other, depending on the size of the cultivator. The surface of the roller consists of rods welded together at intervals. As the roller consists of rods welded onto two rings mounted on an axle pipe, the soil does not cling to the roller which therefore requires no scraper.

Title: White level limiter for colour TV CRT - has white limit dependent on signal derived from brightness control knobs setting
Inventor: DICKHARDT ROLF
IPC: H04N9/64
Filed: 1974-12-16
Abstract: The white level limiting circuit for a colour television cathode-ray tube has the video signal supplied to the cathode-ray tube via a limiter circuit whose limit level is dependent on the setting of the brightness control knob on the front of the receiver. The limiting circuitry itself consists of a transistor stage in emitter-base connection whose bases are supplied with the video signal and whose collectors are coupled over a reverse biased diode to the brightness control potentiometer and to the bases of the emitter followers that feed the colour channels output amplifiers. The reverse biased diode may be coupled to a transistor collector electrode whose collector-emitter path becomes conductive on specified conditions.

Title: A-D converter system with floating point - determines exponent and mantissa of binary number allocated to analogue value
Inventor: ERNST PETER DIPL ING
IPC: H03M1/00
Filed: 1974-12-21
Abstract: The process is carried out in two steps, using a fixed point A/D converter, in series with a preamplifier whose gain is controlled by a multiplying D/A converter. The amplifier gain is set during the first step to its lowest value. The first conversion word is completely decoded to the exponent in a decorder (4), and stored in a memory (5). The preamplifier (2) gain is then increased by the D/A converter (3) so that it is driven in full in the next conversion for the same analog value mantissa determination by the same fixed point A/D converter (1). A read only memory or a priority circuit, may be used for the exponent decoding.

Title: Microwave sterilisation of deep frozen non metallic objects - killing micro-organisms by heating and loss of water
Inventor: JANSSEN GERARDUS
IPC: A61L2/12
Filed: 1975-07-18
Abstract: Sterilisation is carried out by placing glass tubes which are closed at one end below water level in a glass vessel containing salt water. Perforated paper is suspended between the water surface and the top of the vessel, and on it is placed the material to be sterilised, which may be made of rubber or plastic, which has been cleaned with alcohol soln., and which is deep-frozen. The vessel is exposed to microwave energy with a wavelength of 2.5 cm. and a frequency of 2450 MHz. The alternating action of the microwave causes the reciprocating water molecules in the resonator cavity to orient themselves in an electrostatic field. The salt water decomposes into Na+ and Cl- ions surrounded by hydrate shells. Rising of gases together with positively and negatively charged water particles causes the formation above water level of colloidal particles which become slightly heated without prior vapour formation, forming condensation on the objects to be sterilized.

Title: Treating wood chips with sulphite solns - before storage in open air, where immersion is more effective than spraying
Inventor: FISCHER KLAUS DIPL ING DR
IPC: D21C1/04
Filed: 1975-10-27
Abstract: In a process for treating wood chips intended for wood pulp, esp. the wood from deciduous trees, before its storage in the open air and subsequent sulphite digestion, the treatment involving the use of aq. bisulphite- or sulphite-solns. of the alkalis ammonia, the alkaline earths, or their mixt, the wood chips are immersed in the soln. and the surplus soln. adhering to the wood is then removed, after which conveyor belts or pneumatic conveyors are used to transport the wood chips to a heap.

Title: Two stroke oscillating piston IC engine - has coaxial opposed pistons, inter shaft steady bearing and special combustion chambers
Inventor: WAGNER ALBERT
IPC: F01C1/063
Filed: 1976-03-03
Abstract: IC engine has rectangular swing type pistons connected by a central shaft and hub extension to lever arms and connecting rods, whereby piston oscillation is connected to rotation of the crankshaft.
