Title: Wave shed loom weft drive - uses combination of magnets to give low-friction drive action
Inventor: EGBERS GERHARD PROF DR
IPC: D03D47/26
Filed: 1979-03-09
Abstract: The drive mechanism for the weft carrier in a wave shed loom incorporates a thrust magnet pole on the carrier, at least towards the weft carrier, with the thrust action triggered by >=1 thrust magnet of the same polarity facing it on the weft carrier. There is >=1 draw magnet for each thrust at a gap in front and behind them, in the direction of movement and parallel to it, with an opposing draw magnet on the weft carrier with an unlike polarity. The system gives a weft drive mechanism which gives little, friction wear.

Title: Electromagnetic actuator for high speed line printer - has low inertia moving parts and low power consumption
Inventor: BOHG ARMIN DIPL PHYS
IPC: H01F7/16
Filed: 1979-06-29
Abstract: The electromagnetic device can drive the characters in a high speed line printer, typically attached to the output of a computer. Two C-shaped ferromagnetic cores (24,27) are placed face to face with an air gap between opposing limbs. Each core has an individual winding (23,26) enclosing the whole core. The moving armature (18) is located in the air gap. It comprises a carrier of non-magnetic low density material (19) with ferrmagnetic inserts (20,21) at each end. The spacing between inserts corresponds to the spacing between limbs of the core, and the volume of ferromagnetic material is approx. equal to the air gap volume. At rest the inserts are clear of the gap and are linked by the smallest amount of flux. The inserts can be chevron shaped to assist with this requirement. When the coil is energised the armature moves rapidly into the gap. The coil switches off when the in-ine position is reached. Inertia carries the armature on into the working part of the stroke which presses the character against the paper.

Title: Gramophone with tone arm rotatable about two axes - subjects stylus to controlled forward movement so that tracking is kept at straight tangent to groove
Inventor: ENSTON RICHARD GERALD
IPC: G11B3/10
Filed: 1979-08-10
Abstract: The record player has a tone arm rotatable about both vertical and horizontal axes. The stylus is subjected to a component of a controlled forward movement away from the tone arm's center of rotation when the stylus moves to the centre of the record thus holding the stylus axis in a line perpendicular to the record radius passing through the point of the stylus with the record. This arrangement keeps the stylus tracking in a straight tangent to the disc groove. The tone arm can be of two linked parts, the first part being mounted on the chassis for rotation about a vertical axis while the second part, carrying the stylus, is rotatable about vertical and horizontal axes.

Title: Measuring temp. of very small heated analysis samples - by determining electrical property of carrier constituting measurement element, e.g. thermocouple, thermoelement or resistance thermometer
Inventor: FRENZEL PETER-JUERGEN DR
IPC: G01K7/04
Filed: 1980-06-04
Abstract: The method is for measuring the temp. of substances, from which very small quantities are to be extracted to be placed into an analyser and heated up, and gives reliable temp. measurement of the substances. The method involves measurement of a temp. dependent electrical parameter at the point on the directly heated sample carrier on which the substance is placed. The sample carrier may be in the form of a thermo-element (4,5,6) with direct electrical heating. The method involves measuring its thermovoltage, possibly used differential amplifiers (13a,13b) and a voltmeter (16). Alternatively, the sample carrier may be a thermocouple whose thermovoltage is measured, or a resistance thermometer, also with direct electrical heating, whose electrical resistance is measured. The method enables the temp. of the sample to be measured during and before the analysis.
