Inventor: LINDBLOM KURT LENNART
IPC: B65H39/06
Filed: 1989-02-23
Abstract: The invention relates to a device for collecting and turning signatures for forming complete part book blocks. For the purpose of dispensing with an otherwise required separate turning apparatus, the device according to the invention has two identical fan wheels situated horizontally next to one another whose centre lines run parallel to one another and which are driven at the same speed in mutually opposite directions of rotation in such a way that the receiving compartments move downwards towards the despatch conveyor from the discharge station of the signatures, firstly in the direction of the receiving position and then in the direction of the point between the two paddle wheels. The receiving compartments of the two fan wheels are offset relative to one another in the circumferential direction in such a way that, in their mutually facing regions, and as seen in the circumferential direction, each paddle of the one fan wheel protrudes approximately into the centre of a receiving compartment of the other fan wheel. Provided behind the transverse cutting device, as a deflector, is a switchable tongue by means of which the signatures are optionally passed on to one of two conveyors having pairs of belts, each of these conveyors leading to the beginning receiving position of a receiving compartment of one of the two fan wheels. When two different part book blocks are placed one on the other in the collecting cycle, this tongue is switched from its one position to its other position. The despatch conveyor runs in the centre between the two fan wheels parallel to the axes of rotation of the two fan wheels and during the deposition is in the rest position.

Title: Electron beam welding unit providing improved welding quality - provides low impedance current path in form of pseudo-spark switch when high voltage flashover is detected
Inventor: SCHLENK WOLFGANG DIPL PHYS DR
IPC: B23K15/02
Filed: 1989-07-18
Abstract: Device for avoiding welding defects arising from high voltage flash-over during electron beam welding is characterised in that when such flash-over is detected a low impedance current path is momentarily completed, but is opened again in order to test the dielectric strength of the beam generator. Depending on the reestablished dielectric strength, the welding process is immediately continued or the closing and opening of the low impedance current path is repeated successively. The onset of the flash-over is deduced from the ideal/actual value deviations of the beam current, or from similar deviations of the Wehnelt voltage or variation of the Wehnelt current. In order to detect the impending flash-over the signals from determining the ' actual/ideal deviations in beam current and Wehnelt voltage are combined. ADVANTAGE - The process ensures improvement in welding quality.
