Patent DE-2552375-A1 (DE)
Title: Iron for folding back edges of stitched seam - has concave surface moving along convexable supporting seam
Inventor: BULLOCK NORMAN J
IPC: D06F81/00
Filed: 1975-11-18
Abstract: The edge flaps formed on the inside of a stitched seam of e.g. a garment are folded back by locating the seam over a support table having a convex face, and running an iron having a concave face, along the seam so that the edge flaps are folded back through an angle of greater than 180 degrees. The leading end of the ironis pointed to allow it to be initially inserted between the edge flaps and progressively fold them back. The edge flaps are ironed back flat without marking the front face of the fabric adjacent the seam.

Title: Laminated paper insulating block for transformers - has orthogonal ventilating channels to drive off moisture before oil impregnation
Inventor: ELFGREN CARL FREDERIK
IPC: H01F27/30
Filed: 1975-12-13
Abstract: The laminated paper insulating block with air cooling channels is intended for transformers and consists of layered cardboard, or similar material, glued together. The laminations (1-6) have channels (7) running parallel to their planes. The channels of adjacent laminations are at right angles to one another. The channels may be formed either by partially cutting through any given lamination or by cutting through it completely, so that it acts more as a spacer. The advantage lies in ensuring that all moisture is disposed with before oil impregnation begins.

Title: Microwave oscillator with power transistor - is used as heater and is controlled by NTC resistor to give constant temp.
Inventor: SUNKLER ANTON DIPL ING
IPC: H03L1/04
Filed: 1975-12-18
Abstract: The microwave transistor oscillator has high linearity over a wide temperature range by being built into a heated housing. An NTC (negative temp coeff) resistor is used as temperature sensor and its resistance variation controls the bias of a power transistor that acts as heating element in thermal contact with the oscillating transistor. The NTC resistor is connected into a bridge that contains a variable resistor to set the housing temperature. The bridge controls the power transistor collector current via an operational amplifier and a drive stage. The heating power is adjusted by a potentiometer coupled to the amplifier and drive stage.

Title: Multi-system circular knitter yarn feed - has a control disc to power yarn feeds and rotate in either direction for yarns with left or right twists
Inventor: FECKER JOSEF
IPC: D04B15/48
Filed: 1976-03-02
Abstract: The yarn for each system is supplied from yarn store drums on a common carrier ring with a control disc to carry the belt drive to groups of yarns from a drive source. The control disc is driven in a selected direction by the power supply. The control disc can rotate in the direction determined by the drive source through its rotary mounting on a carrier ring.

Patent DE-2621766-A1 (DE)
Title: Tow rope with spring operated return action - has windings formed from operating lever springs giving sufficient play but keeping vehicles at safe distance
Inventor: SCHMIDT HELMUT
IPC: B60D1/18
Filed: 1976-05-15
Abstract: The zigzag construction tow rope has a spring operated return action. This avoids the danger of the rope slipping under the wheels. It maintains the desirable distance between the pulling and towed vehicles and it cannot slacken to rub against the road. The windings are pref. formed from operating lever springs (2) allowing the rope (1) to be sufficiently stretched in a straight line. They possess, however, enough tension to return the rope (1) into a tight zigzag shape. The rope is attached to the vehicles using conventional fastenings. If the distance between the vehicles becomes too great the increased spring tension forces them closer again.

Title: Lift augmenters for aircraft wings - are adjustable by jacks to continuous or slotted flap positions to vary aerodynamic characteristics
Inventor: COLE JAMES B
IPC: B64C9/08
Filed: 1976-05-21
Abstract: The lift augmenters for aircraft wings are primarily intended for STOL aircraft, esp. designs using adjustable wing edge extensions to increase lift. The trailing edge portion of the wing (10) have in their retracted position, two streamlined flaps (24, 34). One (24) pivots about a pin (22) in a bracket projecting down from the wing and the other (34) about a pin (35) partway along the supporting arm (20) of the first, so that normally extended they form a smooth continuation of the wing upper surface curve. A jack (30) between the front of the forward flap (24) and first support arm (20), in conjunction with a pivot (28) further back, allows this flap to be tilted downwards, opening slots along both its edges, altering the aerodynamic characteristics.

Title: Balancing of assembled lifting piston machines - has axially spaced bearings with phase indicator coupled to rotor of machine
Inventor: LANG OTTO DR ING
IPC: G01M1/22
Filed: 1976-11-16
Abstract: To indicate and eliminate chance imbalances on lifting piston machines, the machine (1) is mounted isotropically in bearings (3, 4) which are flexible in two different directions perpendicular to one another. Vibration pick-ups (6, 7, 8, 9) are assigned to the two radial directions for each bearing. A measuring and decoding unit (14) determines separately for each bearing the amount and direction of the imbalance in respect of each radial direction. An average value is then formed vectorially for each bearing from the two imbalances and the data is used to control the machining unit.
