Title: Electrical anti-leakage current insulation - comprises hardened organic polymer insulation contg additive decomposable to dielectric fluid
Inventor: CRANMER JOSEPH W
IPC: H01B3/30
Filed: 1974-10-17
Abstract: Electrical anti-leakage current insulation comprising (a) a hardened organic insulation material which at high electric voltages can decompose with formation of a carbon residue into an electrically-conducting path, (b) 10-25 wt. % (w.r.t. (a)) of an anti-leakage current additive which is homogeneously dispersed in na) and at this voltage is thermally decomposed so that an interrupting path and an electrically isolating, dielectric fluid are formed simultaneously. The path-interrupting fluid may be a gas. The additive may be a meltable solid which becomes liquid at the temp. prod. by the electric voltage. The insulation material is resistant to complete breakdown of insulation caused by over-voltage since carbon conducting paths which form under such conditions are interrupted or isolated by the anti-leakage current additive.

Title: Materials handling manipulator of pick and place type - one memory which stores intermediate location followed by co-ordinate information and return path
Inventor: WEISSGERBER FOLKER
IPC: G06Q10/00
Filed: 1974-10-19
Abstract: A materials handling manipulator in the form of a 'pick-and-place' unit is designed to perform automatic stacking of components in cartons and utilises a memory system of reduced capacity. The manipulator (2) is mounted on rails (4) along which it may be moved. The arm and hand (1) collect components from a pick-up point (A) that may vary before moving through a path (B, C, D or E) to an intermediate location in the carton. An initial memory store provides information for the intermediate position and this is confirmed by a sensor to generate a switch over signal (13). The second main memory then provide co-ordinate information for the required location (a1-a5)(b1-b5) as well as the layer level (5-8). Accurate location is sensed and a third memory provides information for arm return to the start point.

Title: Low current fine wire twisted cables - have terminals formed out of cable material to reduce costs
Inventor: REISCH FRITZ
IPC: H01R11/11
Filed: 1976-02-19
Abstract: The low current connecting cables are formed of twisted fine wires, i.e. Litz wires, and the manufacturing process is intended to eliminate the need for providing and attaching terminal ends. The ends of the cable are deformed under pressure and heat to the required shape and soldered to give a solid termination. In the mfg. process the cable ends may first be heated, then dipped in a solder bath, and finally pressed to the required shape after which the solder is allowed to set giving a solid terminal. This method permits the use of simpler production means and eliminates the cost of providing separate terminal ends.

Title: Air or gas filter esp. for radioactive dust - can be tested for leakage of filter element in situ
Inventor: NEUMANN GERHARD MAX
IPC: B01D46/42

Title: Simultaneous formation of two drill shafts - and part recovery of molten rock for heat content utilisation
Inventor: CLAY RUFUS GORDON
IPC: E21B21/12
Filed: 1976-11-15
Abstract: The recovery of geothermal heat energy from subterranean rock comprises: drilling the earth with a rock melting drill so as to form two distinct shafts; circulating heat absorbing fluid down one shaft, through the drill and up the other shaft; and recovering heat from the fluid. The appts. includes an electric heating element capable of withstanding a temp. of 1200 degrees C and a drill for forming two shafts and moving some of the rock. The drill is such as to allow passage of a circulating fluid between the shafts. Both shafts are drilled together and communicate without recourse to rock fracturing. Additional piping is not required for the circulating fluid nor for excess rock removal. Excessive mechanical force upon the drill is avoided so drill wear is reduced. The force on the heating element is minimal so they may be fabricated from materials which allow higher temps. to be attained.

Title: Rolling mill for mfr. of seamless tubes from billets - using a skew rolling mill with mandrel or hole press
Inventor: BRETSCHNEIDER ERICH
IPC: B21B19/06
