Title: Setting integrated circuit leads to predetermined pattern - is by use of separator pins and positioning jig with holes in pattern required
Inventor: PLOCK REINER DR ING
IPC: H05K13/02
Filed: 1979-01-26
Abstract: In printed circuit boards, certain components, particularly integrated circuit operational amplifiers, have a number of leads which require connection to the printed conductors. Where a dual-in-line package is not used, these leads are not necessarily parallel when the component is received. To arrange the leads in the required pattern, a series of separator pins (A) are inserted close to the component (BE) base, one pin between each lead. These pins are then moved towards the free end of the leads. At this point the wire ends are entered into a jig. The jig has holes in the required pin pattern, and each hole has a tapered entry for the wire lead. The pins are withdrawn and the jig pushed up to the base, bending the leads into the required pattern in the process. The component can thus be fitted to the circuit card with little risk of a wrong connection.

Patent DE-2940120-A1 (DE)
Inventor: HAUSMANN EDGAR DR ING
IPC: C25B11/03
Filed: 1979-10-01
Abstract: Composite bipolar electrode (1) for electrolytic cells having drilled anodes (8) and cathodes (11) and wherein the separation (9) (10) of the anolyte and catholyte spaces is tight to liquids and gases. It allows a good contact between anode and cathode and simultaneously a lightweight execution of the partition wall, thus allowing the saving of materials. This is achieved since the partition wall is provided by a thin sheet (10) comprised of a material which withstands the conditions prevailing in the anolyte as well as to those prevailing in the catholyte. This sheet bears against the grid (9), made of expanded metal, for example, which is arranged at the side where the low pressure prevails. The grid (9) is set at regular intervals on the electrode at the high pressure side and is tightened between the anode and the cathode at the contact locations (13) where the current flows, thus resulting in a partition between the anolyte and the catholyte, tight to liquids and gases.

Patent DE-2951635-A1 (DE)
Title: Wind power unit with vertical rotor shaft - uses counterweight of pendulum system to move rotor automatically out of wind when its force exceeds threshold
Inventor: OHLBERG KARLHEINZ ING GRAD
IPC: F03D7/02
Filed: 1979-12-21
Abstract: The rotor (or rotor plus connected working machines) is mounted in a pendulum system about a pendulum axis horizontal and at right angles to the rotor shaft. The stable balance at the heavier lower end of the pendulum system keeps it in its working position when the wind is still. As a consequence of various large wind resistant surfaces, i.e. various large torques at a prevailing wind at the upper and lower parts of the pendulum system, it tends to move automatically out of the wind as the latter increases in force until at storm strength, it moves to feathered pitch. The pendulum system is registered in a click-stop arrangement by an arrester, e.g. catch or magnet, is that it is held in an efficient working position for weak or nromal working winds. It is only released when the wind strength exceeds a threshold value.
