Title: Short-circuiting circuit for protection of electronic components - has adhesive strip applied across flat connecting strips to shunt them if static charge builds up
Inventor: PFALZNER JOHANNES ING GRAD
IPC: H01R13/658
Filed: 1978-07-14
Abstract: The protective circuit contains overvoltage sensitive components to protect against discharge of a static charge during prodn. and/or transport of electronic components by provision of flat connections on one or more planes. The short-circuiting device consists of a self-adhesive strip (8) with a through metal conductor along its entire length. The strip (8) is applied across the flat connections (7). The electronic components (3, 4) can be already positioned on a circuit board (1) connected by flat leads (2).

Title: Pneumatic door drive control mechanism - has spring loaded regulating valves for exhaust pressure reduction, braking door movement
IPC: E05F15/50
Filed: 1978-10-24
Abstract: A cylinder activated on both sides a reversal valve and choke return valves in the cylinder feed ducts are incorporated in the control device for pneumatic drive on a door-operating mechanism. A spring-loaded regulating valve (1.3, 1.5) is circuited parallel to each choke return valve (1.2, 1.4), allowing exhaust pressure (Pa) in the exhaust duct to fall rapidly to a mean level (Pm). The through-flow volume in the return valve concerned is set low enough for exhaust pressure resulting from piston movement to rise rapidly from mean pressure, leading to gentle deceleration of the moving door. The door accelerates initially during both opening and closing, and ends with a gentle movement.

Title: Stacked collapsible trestles forming transportable pallets - have specially dimensioned top and bottom rails to ensure inter-stacking
Inventor: LEHNERT PETER
IPC: B25H1/06
Filed: 1980-06-26
Abstract: The collapsible trestle comprises a rectangular frame with two parallel leg members (14) supporting at the top a bearing rod (16) and connected at or near the bottom by a support stay (20) wherein the internal height (C) between the bearing rod and support stay is equal to or less than the external width between the leg members (14). This allows the trestles which can be stored per volume unit of the pallet to be practically doubled thus considerably reducing the transport costs. The pallet formed by this increased number of trestles has a very high inner stability especially if the length of the top bearing rod is greater than the internal height. The pallets can now be handled by fork lift trucks and trestles of two different dimensions can be combined in to single pallets. The trestles are pref. made into pallets by stacking trestles alternately with their bearing rod top and bottom.

Title: Anti-tilting device for fuel element container - is cage surrounding container and attached to articulated restraining frame
Inventor: WALTER HEINZ ING GRAD
IPC: G21F5/14
Filed: 1980-07-05
Abstract: The Parent patent describes an anti-toppling or anti-tilting device for (shielded) transport containers for nuclear fuel elements in nuclear power plants, reprocessing plants etc. The device comprises an articulated frame, firmly anchored at one end to a structural wall and having a rod at the other end, which is articulated to and sliding relative to the container, so that it maintains it upright if the lifting equipment should fail. This device permits horizontal and vertical movement of the container. In the patent of addition, the rod at the free end of the articulated frame forms part of a cage, which surrounds the transport container with clearance inside it. The parent patent permitted horizontal and vertical movements of the container without the need to dismantle safety platforms and the like. In the patent of addition, the necessity for accurately aligning the rod with a slide tube fixed to the container is removed, since the cage surrounds the container with appreciable clearance.
Patent DE-3028851-A1 (DE)
Title: Transfer of hot roller prods. onto cooling bed - via pushers which can move either ribbed steel bars, or profiles which can easily distort while hot
Inventor: KIRCHHOFF HANS
IPC: B21B43/00
Filed: 1980-07-30
Abstract: The prods. consist of either ribbed steel bars (I) which are not easily damaged, or steel profiles (II) which are easily damaged. Both types of prod. are fed along an inclined roller track in a gutter, which contains two rows of brake pushers (a,b); and the pushers are reciprocated vertically to feed the prods. onto a cooling bed. To feed ribbed bars (I) onto the bed, pusher (b) is kept in its top position, whereas pusher (a) is used to brake the bars (I) and to lift them onto pusher(b). For profiles (II), pusher(a) is kept in its lowest position while pusher(b) lifts the profiles so they can be picked up by the moving rakes of the cooling bed. There is no longer any need to change the pushers in the gutter when the type of rolled prod. is changed, i.e. one gutter can cope with both types (I or II).
