Title: Melt spinning and drawing - spun thread is pre-drawn at speed with a subsequently final drawn continuous process
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D02J1/22
Filed: 1972-01-31
Abstract: A melt spin and draw process has a pre-draw at >3000 m/min. and a ratio between 1:1.8 and 1:1.3 final draw in a continuous process with not >1 heating step. Polymer is extruded through a spinneret down a cooling stack and forwarded by a godet at, e.g. 3400 m/min. (a pre draw of 1:115). The godet is heated to 145 degrees C. A draw godet gives a final draw at a ratio of 1:1.75. Polyester so produced has a breaking load of 4-9 g/den. and breaking extension of 25%. A treatment chamber in the draw zone has a steam or other required atmos. Draw point is well defined.

Title: Polymerising fatty acids - in presence of catalytic clay, steam and active carbon
Inventor: BURBA CHRISTIAN DIPL CHEM DR
IPC: C07C57/03
Filed: 1972-05-31
Abstract: unsatd. fatty acids are polymd. at 200-280 degrees C without application of press., in presence of 1-20 wt. % of catalytically active clays, which may be modified by addn. of alkali(ne earth) cpds., (Li cpds.), and in presence of steam which is led through the reaction mixt., pref. in finely divided form. Esp., the steam velocity is such that no, or little, fatty acid is expelled during the 1st stage of the polymerisation, and that unconverted fatty acids are expelled in the 2nd stage, after completion of the polymn. In the present improvement, 0.1-1% of active C is added to the reaction mixt. The characteristics of the polymer acids, esp. the colour value and odour, are improved. Monomer acids, esp. the colour value and odour, are improved. Monomer acids occurring as by-prod. are of better quality. Dimer acids are esp. suitable for hydrogenation.

Title: Helically profiled anchor bolts for concrete or rock - are fastened into boreholes by resin mortar
Inventor: WOLTER RUDOLF
IPC: F16B13/14

Title: Screw plasticiser with rear gas vent - has obstructions preventing entrainment of plastics by escaping gas
Inventor: OCKER HERBERT DR ING
IPC: B29C48/67
Filed: 1973-06-06

Title: Tube bending using induction heating coils - with two yokes to control heat input at the inside and the outside of the bend
Inventor: KLOSKA GEORG
IPC: B21D7/16
Filed: 1973-06-07
Abstract: The parent patent describes the hot-bending of tubes, where the inside of the bend is heated to the bending temp., but the remainder of the periphery (which will form the outside of the bend) is kept at a lower temp. Induction coils are used to heat the tubes, with a yoke being provided at the inside of the bend for concn. of heat at this point. In the present invention, a yoke is also used adjacent to that part of the tube which will form the outside of the bend, but in this case to direct the heat away from the tube, i.e. two yokes with opposite functions are now employed. This modification applies esp. to the induction coil used on the bending line, the object being to obtain better temp. distribution. Laminated keepers are used in conjunction with the yokes employed on the outside of the bend, the distance between the yokes and the keepers being adjustable, i.e. the heat-input can be regulated.

Abstract: The lay of the anchor chain of a pipe laying sea craft can be determined automatically along an inductive path. The total measurement trajectory is covered by a stray field of a magnetic circuit. The measuring windings envelope a yoke which covers the whole span of the field. Useful flux is generated by a pair of booster windings outside the measurement trajectory. These are linked to the yoke flux and are symmetrically mounted with respect to the measurement trajectory. The windings are in flux opposition.

Title: Microwave therapy radiator - has additional reflectors for narrowing beam and altering characteristic
Inventor: ZIMMER PETER
IPC: A61N5/04
Filed: 1973-09-25
Abstract: Microwave radiator for high-frequency therapy has the radiator in an elongate rectangular reflector hood with additional reflectors, to produce a radiation beam emerging centrally through the opening of the hood, with a small radiation cross section w.r.t. the length of the opening. The additional reflectors are displaceable w.r.t. the reflection surfaces of the hood in the region of the opening such that they lie selectively in the beam, to change the radiation characteristic of the radiator, and deflect part of the beam onto parts of the reflecting surfaces which otherwise receive no, or only scattered, radiation, or else the additional reflectors are completely out of the beam path, or only in the scattering region. Changeover from diffuse to narrow-beam radiation and vice versa is easy, without disconnection.

Title: Improved suspension for caravan - with separate dampers for vertical and torsional forces to relieve transverse forces on torsion element
Inventor: KOBER KURT
IPC: B60G15/02
Filed: 1973-10-10
Abstract: The wheel of the caravan is supported at the upper end of a vertical suspension arm, with the bottom end fitted with a horizontal section which is secured to one part of a torsion element formed by an outer shell ecured on a shaft by bonded layers of rubber. This absorbs longitudinal forces on the wheel. The tension element shaft is joined to a forked lever whose inner ends are hinged on the chassis frame to swing about a longitudinal axis to provide vertical movement of the suspension. The vertical forces are supported by a vertical damper located between the torsion element and the chassis. In this way the weight of the vehicle is taken off the torsion element so that it can function better.

Title: Axially compressible elastic yarn bobbins - for use e.g. in yarn dyeing
Inventor: FRITZ WILLI
IPC: B65H75/24
Filed: 1974-02-25
Abstract: In an axially resilient compressible conical or cylindrical winding support or bobbin for the treatment, e.g. dyeing, of yarns, of the known type having two end rings and a series of intermediate rings connected by elastically flexible, axially parallel struts or strut-type grids mounted in the peripheral surface and having theoretical flexing or kinking positions, the improvement whereby the cross-section of the struts is so designed that on axial pressure loading of the bobbin, they are deflected radially towards the bobbin axis. Provides a considerably greater area of cross-section for the passage of a treatment liquid through the yearn package when the bobbin is axially compressed than the known designs, thus enabling the bobbins to be compressed to a greater extent and permitting an increased number to be mounted on the sword-type carrier.

Title: Three, interconnected single, phase transformer - has DC excited control and zig-zag connected transformer with series-parallel tuned ccts.
Inventor: KLEIN GUSTAV
IPC: H02M7/06
Filed: 1974-03-04
Abstract: Control circuit for three phase transformer made up from three single phases using d.c. excited control windings introduced in openings in the yoke of the magnet core. These are used to vary the resultant flux through the main windings. This will equalise the effect of unsymmetric loading at the output by a balancing effect at the input. The secondaries are connected to a zig zag connected transformer which has a tuned circuit in each phase. The circuit is connected in parallel and is tuned to the fundamental frequency. It consists of a parallel resonant circuit for the fundamental and a series resonant circuit to compensate for the harmonics. The no load impedance of the zig zag transformers produce the required inductance for the tuned citcuit.

Title: Animal-lifting stand with frame - has crank operated cable winches for pulleys and grooved rollers for lifting harness
Inventor: KOEHLER HEINZ
IPC: A01K15/04
Filed: 1974-04-30
Abstract: The stand extends the length of the animal's body and has uprights, cross-pieces, diagonal reinforcements and cable drums operated by cranks. Lifting straps and cables run over rollers. One end of the cables is fixed to the cross-pieces, whilst the other end is wound on pulleys.
