Title: Large panel handling tongs - have scissor arms with hinging jaws and cross-arms pivoting on handle
Inventor: STEGHERR LUDOLF
IPC: B65G7/12
Filed: 1977-06-07
Abstract: The handling tongs transport large panels of chipboard, hard fibreboard, plastic, glass etc. using a carrying handle and jaws gripping the panel between them and closing under load. They have two scissor arms (1, 2) hinging together and crossing, with the jaws (4, 6) hinging on them at one end (5, 7) while at the other (10, 12) is a pivoting cross-arm (9, 11). The handle (14) hinges on the free ends of the two cross-arms. The hinge point (3) between the scissor arms can be closer to the jaws than to the cross-arms, and the jaws can be eccentrically-mounted on their pivot spindles. They can be of plastic, metal or hard rubber.
Patent DE-2727744-A1 (DE)
Title: Continuous heat treatment of steel sheet - quenched in water contg. an organic acid to prevent oxidn. during quenching
Inventor: PAULUS PHILIPPE
IPC: C21D9/573
Filed: 1977-06-21
Abstract: In the continuous heat treatment of rolled sheets, where the sheet is quenched in an aq. bath, the novelty is that the bath contains organic acids, pref. with a short chain of carbon atoms. The pref. bath contains formic acid or acetic acid, and it pref. also contains surfactants and/or reducing agents. It is used for example on steel sheets possessing a high elastic limit with high elongation suitable for deep drawing in the automobile industry. Prevents the oxidn. of the surface of the steel during quenching, the corrosive action of the organic acids is easily arrested after quenching, unlike mineral acids. A reducing agent such as hydrazine can be added to the bath to decrease the amt. of dissolved O2, reducing the amt. of oxide formed and also reducing acid consumption.
Patent DE-2729600-A1 (DE)
Inventor: WUESTER HEINRICH ING
IPC: A47C23/06
Filed: 1977-06-30
Abstract: In bedsteads having slats (1) which are arranged spaced apart transversely to the longitudinal supports (4) of a support frame and are mounted on the longitudinal supports (4) in bearing bodies (2) fitted onto their ends, there is the problem of achieving as far as possible unimpeded pivotability of the slats (1) about their longitudinal axes because the slats can only in this way adapt sufficiently to the changing direction of loading in accordance with the different body positions of the user. The solution provides for projections of the bearing bodies (2) which are located opposite the underside or upperside of the slats (1), are arranged centrally relative to the slat width and receive the slat ends between them substantially without play. Appropriate cambering of the inner surfaces of the bearing bodies may possibily fulfil the same purpose. The slats can thus carry out the desired pivoting movements with their cross-section. Central projections also on the surfaces of the bearing bodies located on the end faces of the slats further improve the easy pivotability by reducing the end-face friction. <IMAGE>

Title: Low density polyethylene tubing for sealing tunnel lining infills - made from extensible tear resistant film for durability against rough surfaces
Inventor: LEWER HANS
IPC: E21D11/15
Filed: 1978-01-07
Abstract: Flexible tubing for lining tunnel walls, and to be loaded in situ with a filler, to bridge the space between the tunnel sleeve and the rock face, is made from high pressure (low density) polyethylene film, with the following characteristics - inclusion of fire retardant and antistatic additives, tear strength (longitudinal and transverse) >=15 N/mm2, elongation to break of >=450%, a needle penetration resistance >=1.5J and a tear propagation resistance >=17N/mm. The tube is laid at intervals over a slatted structure covered with a layer of flexible film, and inflated to provide a buffer support between the leading section of the tunnel sleeve and the crude tunnel wall. As successive 10-50 m sections of the sleeve are added, the spaces between the tubes are filled with e.g. concrete, fine rubble, etc. to provide a permanent interlayer for spreading the pressure of the tunnel wall uniformly over the lining structure. The pressurised tubes adapt to the crude wall surface without puncturing to provide initial support and exclude entrapment of explosive gases and allow infill materials to be promptly cast without contaminating the working face of the tunnel.
