Title: Continuous dyeing - of all types of textile materials at high speeds
IPC: D06B3/20
Filed: 1971-06-07
Abstract: Textile materials of all kinds are continuously processed, particularly treated with solvent dyes, and simultaneously fixed by dipping the moving material in the treatment bath for a specific residence time and forcibly passing the treatment liquid through it until it is wetted and fixed.

Title: Controlled fusion - from opposing plasma streams in pulsed orbital packets
Inventor: NOWAK KARL ING
IPC: H05H1/22
Filed: 1972-10-26
Abstract: Fusion of deuterium atoms by collision of two opposing streams of plasma 'packets' within a graphite lined reaction chamber surrounded by a rotating coil applying a magnetic field to the accelerated ions and electrons.

Title: Air humidifier for central heating radiator - has a mechanical water reserve indicator which is spring actuated
Inventor: SACHSE SIEGFRIED
IPC: F24D19/00
Filed: 1973-07-09
Abstract: The humidifier consists of a vessel with a water reservoir and an evaporating wick. Is is attached to the radiator by means of a wire hanger. The hanger incorporates a weak spring near its attachment to the humidifier. An indicator panel is fixed to the hanger above the spring so that it covers a mark on the humidifier casing when the spring is extended and the water reservoir is full. The mark becomes progressively visible as the water evaporates and the spring contracts with reduced weight. The design can be varied by using a lever to magnify the relative indicator movement. For top standing units a compression spring in the tray is used in a similar way.

Title: Compensation cct for async. motor power pulsations - simulates pulsations to alter inverter control parameters
Inventor: ABRAHAM LUDWIG DIPL ING DR
IPC: H02P27/06
Filed: 1973-09-29
Abstract: The compensation circuit controls an inverter supplied asynchronous motor power pulsations, by varying the control parameters of the inverter DC/AC part about a constant mean value. Varying the parameters controlling teh frequency of the stator voltage or current produces pulsations of opposite phase to the power pulsations. The simulation circuit copies the power fluctuations at the rectifier output and passes them to two comparators whose outputs control the inverter. The output of the inverter is monitored, compared with one comparator output and the result used to control the current regulator coupled to the inverter.

Title: Thermomagnetic generator using Nernst-Ettinghausen effect - comprises layered structure as energy transducer
Inventor: HAERINGER JOSEF
IPC: H02N11/00
Filed: 1974-02-01
Abstract: Thermomagnetic generator utilises an e.m.f. set up by establishing a temperature gradient in a conductor and causing the electrons to move by placing the conductor in a magnetic field to deflect towards the tendency to travel from the hot to the cold end of said conductor. The generator uses cryomagnets or superconducting windings to create the required magnetic field. The thermomagnetic generator can be used to convert thermal energy into electric energy in place of generators and turbines, provided that a suitable energy transducer-conductor is used over all temperature ranges. The claimed energy transducer converter specifically consists of several layers of different materials arranged in coils.

Title: Shelving comprising uprights and slot in shelves - has no extra fastening members but uses weight of articles on shelves
Inventor: DRAENERT PETER DR
IPC: A47B57/10
Filed: 1974-02-15
Abstract: The wall shelving is made up solely of uprights and horizontal shelf panels which fit into slots cut into the end sides of the uprights to open towards the outside. If it is desired that the shelf abuts the wall, the shelves can have recesses to fit the uprights. The slots in the uprights are lined with U-shaped plastic inserts which are corrugated to ensure a perfect fit of the shelves. The slots are slightly larger than the thickness of the shelf. The outside of the uprights can for example be finished with plastics or chromium-plated in the normal way. The weight of articles on the shelves causes the shelf to cant slightly thereby holding the shelf firmly in the slot.

Title: Concrete component handling tackle - has nipple on rope end bearing against expanding bush with spring tongues
Inventor: MOSER KARL
IPC: E04G21/14
Filed: 1974-08-02
Abstract: A length of tube is firmly anchored in the concrete component and contains a bush, against which a nipple on the end of a loop of rope bears. The rope (9) moves freely in the bush (6), and below the centring collar (7) the bush is of the expanding type with spring tongues (12) accommodating the nipple end (14). The bush also has a taper face (15), bearing against a mating face (16) formed in the tube (2). This mating face can be formed by a double-truncated cone portion of the tube, reducing the clear diameter of the latter. The flanged part of the tube, abutting the concrete component, is smaller to allow for the tongues formation.
