Title: Shoe for steam iron - consisting of aromatic polyamide cloth stretched over a framework
Inventor: KONSTANTINE DIKOFF JOSEPH
IPC: D06F75/38
Filed: 1969-02-01
Abstract: A shoe for attachment to a hand steam iron consists of a frame which can be attached to the sole of the iron with a thin sheet of fibres of aromatic polyamide stretched over it. The sheet is less than 1/16 inch thick and allows the steam from the iron to pass freely through it.

Patent DE-1946813-A1 (DE)
Title: Plates for printed circuits
Inventor: SCHICK JOSEF
IPC: H05K3/38
Filed: 1969-09-16
Abstract: The plates are produced by applying onto an insulating base (made from phenoplast, aminoplast or epoxy resins) a continuous layer of a condensation resin containing a monomeric or polymeric compound(s) having an ester group(s); then subjecting this compound(s) to alkaline saponification and leading it out from the resin. Subsequently the plate is sensitized, activated and metallized by known methods (screen-printing can be applied). The spots from which the saponified ester groups have been removed present good anchorage points for the metal coating. The electro-insulating properties of the plate are not impaired.

Title: Doppler double sideband omnidirectional radio beacon - signal format is matched to precision-DVOR system
Inventor: HOEFGEN GUENTER DR ING
IPC: G01S1/40
Filed: 1974-02-28
Abstract: A central antenna transmits an amplitude-modulated first signal at frequency fo and two individual radiators transmit second and third signals at frequencies fo + f, and fo - f, cyclically in one sense of direction and fourth and fifth signals at frequencies fo + f2 and fo - f2 in the other sense, whereby the azimuth is obtained by a receiver from the phase difference of the demodulated signals, as in 2160731. The resultant of the fourth and fifth frequencies is transmitted in phase quadrature to the resultant of the second and third frequencies, and the fourth and fifth signals are demodulated together in the receiver. Although the signal format is matched to the precision-DVOR system, the geater precision of the beacon over the latter system is retained.

Title: Welding of rolled lorry wheel rims - equipment and conveying reduced to minimum for mass production
Inventor: FENCL VERNON
IPC: B23K11/04
Filed: 1974-07-16
Abstract: Because different thicknesses are needed in different zones a lory wheel is made from rolled raw material (as distinct from the sheet material used for car wheels), subsequently bent to shape. The equipment is concerned with finishing the rim in preparation for welding. A machine receives rims on a roller conveyor, positioned with their axes vertical. A clamp grips a rim and transfers it to a workholder in which it is lowered to an operating position. The ends are first formed to true circular shape and are then trimmed. Next the rim is reformed to press the ends together ready for welding after which it is raised again, gripped by the transfer clamp adn laid on a conveyor for transfer to the welding station. Trimming, pressing, and deburring are carried out after welding.
