Patent DE-2261131-A1 (DE)
Title: Radiant energy concentration rig - uses annular plasma radiator in focus of conic section defining reflecting body of revolution
Inventor: LEONHARDT RAPHAEL DR
IPC: H01S3/042
Filed: 1972-12-14
Abstract: The electromagnetic energy of an annular radiator is concentrated by using a body of revolution for reflection. The reflector is so designed that the energy is focused at a point which lies, (a) in the axis of rotation of the body of revolution and, (b) in the principal axis, at right angles to the axis of rotation, of an ellipse which defines the body of revolution. This results in a far higher energy concn. than with a point source and is suitable for continuous operation.

Title: Two stage soy bean-prod. steam treatment - in horizontal fluidised bed reactor, destroying bitter principles without denaturing albumin
Inventor: LEONHARDT MICHAEL
IPC: A23L5/20
Filed: 1973-08-07
Abstract: Soy bean prodts. are steam treated to remove the bitter principles in a fluidised state in two successive stages. The carrier fluid in the first is gas and steam which heats the material by condensn. of steam on it while the gas keeps it in suspension. The carrier fluid in the second stage is steam and/or gas which sustains a treatment temp. to destroy the bitter principles and/or inhibitors. This eliminates denaturing of the albuminous nutrients, and it makes them more digestible and suitable for more sensitive alimentary processes. The treatment takes only 5 minutes.

Title: Safety device for fly mower - grass cuttings and foreign objects discharged via rotating vane
Inventor: NEUMEYER DIETER DIPL-KFM DR
IPC: A01D34/82
Filed: 1973-08-08
Abstract: A motor mowing machine of the type with a horizontally rotating blade and a discharge orifice for grass cuttings is provided with a safety device to protect the operator from ejected stones etc. Grass mowings stones etc. pass from the mowing machine along a duct and past a freely rotatable varied rotor. The rotor is a surrounded by a closely fitting housing. The rotor is driven around by the relatively low speed of the grass cuttings and air draft. If a fast moving stone is ejected the wind resistance of the vanes in the housing slow it down to a safe speed.

Title: Actuating system for hydraulic press with fast and working stroke - has coupled hydraulic systems for driving the ram and auxiliary equipment
Inventor: ADAM KLAUS
IPC: B30B15/16
Filed: 1973-09-17
Abstract: The press system has two main systems which are supplied with pressurised hydraulic oil. These systems are used for driving the press ram or the cutting punch. The other system is used for actuating the auxiliary equipment such as that for feeds and bolster plate. High pressure pumps for supplying both systems are connected so that during the rapid return stroke and during the working stroke they act jointly on the connected high pressure system and during the remaining time within a pressing cycle they are connected individually or together to charge the hydraulic accumulator of the low pressure system. Both systems can be supplied from a single high pressure pump and the oil supplied is diverted by suitable valves to the rapid return and the working cylinder. The full oil flow is used for charging the low pressure system during the remaining time.

Title: Multi module biological function simulating systems - changes position automatically by magnetic attraction and repulsion
Inventor: STELTER MANFRED
IPC: G09B23/00
Filed: 1973-10-01
Abstract: The module is in the form of a box, e.g. square or hexagonal, containing an electronic circuit and one or more magnets on the walls to attract or repulse other modules. The magnets are controlled by a current fed to a coil from a chemical battery as a function of information supplied to the module and picked up by a receiver. Part of this information relates to the actual position of the module in a multi-module arrangement and a separate part relates to the desired shape and size of the arrangement. The information is processed by the electronic circuit and used to move the module to the desired position by magnetic attraction and repulsion against the other modules.

Title: Direct current electrically operated valve - has solenoid operating valve body biassed back to seats of permanent magnetic material
Inventor: NEUSEL ROLF
IPC: F16K31/02
Filed: 1974-01-05
Abstract: The valve consists of an inlet and an outlet or two inlets between which the valve element is mounted and one outlet. The two inlets face one another and are provided with valve seats made from permanently magnetic rings. Between the two valve seats, a magnetic core is mounted which is manufactured from a magnetic material with low remanence. A coil is wound round the core, the coil wires extend in one direction through the housing and are at the same time used to provide mechanical support for the valve element. The valve lies against one of the permanent magnet valves seats. If a D.C. pulse is passed through the coil, which is large enough to build a magnetic field in the core with low remanence, this field will counteract the field of the permanent magnet and the core will be pushed against the opposite valve opening.

Title: Reaction element for catalytic hydrocarbon conversion - has several spiral inner tubes inside straight outer tube
Inventor: MARTENS GERHARD
IPC: B01J10/00
Filed: 1974-02-06
Abstract: The parent patent describes reaction tubes for the chemical conversion by hydrocarbons by steam or air, filled with a catalyst and having a wavy, helical or spiral internal heating surface. In this patent the number of such internal tubes inside an external tube is increased to that made possible by the external tube diameter and by the particle size of the catalyst. This raised the thermal efficiency and the scope for these tubes and reduces the amount of metal required.

Patent DE-2408098-A1 (DE)
Title: Tube mfr by seam welding formed strip - using induction coil for pre-heating, to increase the welding speed
Inventor: FLICK KURT
IPC: B23K9/025
Filed: 1974-02-20
Abstract: In butt welding the edges of slit tubes in tube mfr. by longitudinal or spiral seam welding, the pre-formed tube travels continuously at a prescribed speed through an aligning device which closes the gap between the longitudinal edges prior to welding, and an induction heater is located ahead of the welding unit for pre-heating the gap. A ring-shaped induction coil is located round the slit tube, ahead of the aligning device, for generating an alternating field along the tube axis, and an electrical insulator is used to hold the two edges apart until they reach the aligning device. The leads carrying the current to the induction coil do not run along the seam so that inconsistent pre-heating does not occur.

Title: Bipolar summation cct. with unipolar output - provides polarity information using delay chain and trigger feed to linear output gates
Inventor: FRITSCHE PETER DIPL ING
IPC: H03K5/156
Filed: 1974-03-08
Abstract: The bipolar summation circuit gives a unipolar output with polarity information and can be used in fast analogue-digital converters. The bipolar input signal is applied to a delay chain and to a trigger. The delay chain output is passed over an impedance converter to a first linear gate. A tapping along the delay chain is connected over a polarity reversing stage to a second linear gate. The outputs of both gates are connected to the summation circuit output terminal. The gates and the trigger are controlled by the same control circuit. The output for the polarity information is taken from the trigger.

Title: Signal transmission system with converting CRTs - uses TDM operation and two-dimensional beam(s) deflection system for connection selection
Inventor: PORTSCHT RAINER DR ING
IPC: H01J31/06
Filed: 1974-05-02

Title: Terrestrial magnetic field survey instrument - has a quartz variometer and deflecting coil
Inventor: BURTSEW JURY ALEXANDROWITSCH
IPC: G01R33/038
Filed: 1974-05-20
Abstract: The measuring apparatus has a low-frequency generator for periodic vibrations which is coupled electrically to a converter (62) of variations in the earth's magnetic field into a digital code, lies in the circuit of a deflecting coil and generates an alternating magnetic field with an amplitude greater than that of the variations to be measured. Under the effect of the generator the magnet vibrates and a light beam is displaced. A photo-receiver is arranged rigidly so that at the moment of balance of the measured variation by the alternating magnetic field an electrical signal occurs at the photo-receiver output which controls the converter.
