Patent DE-3003109-A1 (DE)
Inventor: JITIANU GHEORGE DIPL ING
IPC: B23H7/04
Filed: 1980-01-29
Abstract: According to the method, the speed of advance is modified so as to keep the voltage level between the electrodes within a given range at the moment of each discharge. A logic device (SL), which includes three comparators, determines the voltage reached and causes the speed of advance to be increased, maintained or decreased, depending on this voltage. In this manner, the working gap between electrodes remains relatively constant throughout the entire machining operation, independently of the speed. <IMAGE>

Title: High speed dissection of spent fuel elements - by high pressure water jets
Inventor: ERNST PETER DR ING
IPC: G21C19/34
Filed: 1980-03-01
Abstract: Spent fuel elements from light water moderated boiling or pressurised water reactors have to be cut into short pieces (5 cm) for a dissolution in acid and for the recovery of uranium and plutonium The cuts are performed by directing a high pressure water jet (400 bar, up to 4000 bar) against the fuel element can. This prevents the fuel dissolution, encountered by a chemical dissolution of the can material and the dust produced by mechanical methods of cutting. A fuel element need not be broken down into fuel rods and the frequent exchange of cutters is saved.

Title: Fly-frame with counter-clockwise rotating spindles - suitable for bobbin lead slubbing winding with conventional flyers
IPC: D01H1/04
Filed: 1980-03-25
Abstract: A fly-frame producing slubbings of cotton, wool or synthetic fibre employs flyer-lead bobbib-winding, in which bobbin and flyer rotate anti-clockwise, such as to insert S-twist into the slubbing. The spindle (16) carrying the bobbin (16) rotates in an anticlockwise direction (B), the flyer (10) rotating similarly (B') at a higher speed. The machine can use the same flyers as previously used for bobbin-lead winding, obviating the need for an additional set of flyers with reversed press-fingers, giving savings in capital expenditure, storage costs and machine setting-up time. Flyer-lead winding gives increased output by enabling the delivery-roller speed to be increased above the maximum speed which is possible with bobbin-lead winding.

Title: Insulation of non-assembled printing circuit card - by applying two layers of solder inhibiting lacquer on each side
Inventor: SUESSKIND EGON
IPC: H05K3/28
Filed: 1980-07-17
Abstract: The object of the proposed surface treatment is to eliminate a manufacturing stage in circuit card production by omitting final coating of the under side of the card with insulation varnish. The proposal is to use the solder flow inhibiting lacquer also as an insulator. Two separate layers of solder flow inhibiting lacquer are applied to the card. This lacquer is printed on leaving the solder points exposed. The thickness achieved with the two layers gives an electrical insulation strength which is the equivalent of the previously used varnish treatment. Both sides of the circuit card are treated before the assembly of the circuit components. Thus one separate stage is removed from the mfg. process and at the same time the handling of the card simplified.
