Title: Section wire mfr - by rolling with hard metal rollers for woven steel fabric
IPC: B21B1/16

Title: Surgical blood-vessel clamp - has elastic sleeve with hole to receive flexible ligature looped about blood vessel
Inventor: WOLVEK SIDNEY
IPC: A61B17/12
Filed: 1974-01-21
Abstract: Surgical blood-vessel clamp has an elastic sleeve with a hole bounded by an inner wall, to receive the ends of an elongate flexible ligature that forms a loop about the section of the vessel to be shut off. A unit on the sleeve releasably presses together sections of the inner wall. The sections come into engagement with the ligature and can thus hold the clamp in the vessel-closing state. Preferably the compressing unit has a clip with a pair of opposite sides with opposite, inward-directed projections, each cooperable with one of the opposed sections. The clamp acts quickly and easily, and occupies little space in the operation field.
Patent DE-2403701-A1 (DE)
Title: Regeneration of catalysts in methane prodn. - from hydrocarbons, by substitution of hydrocarbons by methanol during use
Inventor: SCHWARZMANN MATTHIAS DIPL CHEM
IPC: B01J23/94
Filed: 1974-01-26
Abstract: Methane-contg. gases are produced from 2-30C hydrocarbons, using Ni on a carrier as catalyst, by passing steam at pressures >1 atmos. and pre-heating to >250 degrees C to produce a temp. of 300-600 degrees C in the catalyst bed, in which the catalyst is simultaneously regenerated by wholly or partly replacing the hydrocarbon feed with methanol. Used for the mfr. of rich gases e.g. for use as natural gas substitutes. De-activation of the catalyst by carbonaceous deposits, as shown by a steady migration of the temp. profile through the bed, is reversed. Subsequent de-activation is not significantly faster e.g. half the original activity, as measured in bed thickness, can be maintained. Production of gas is not interrupted or permanently reduced.
Patent DE-2410208-A1 (DE)
Title: Telescopic extension mechanism for cupboard mounted tables - has double telescopic guide providing greater stability in extended position
IPC: A47B1/10
Filed: 1974-03-04
Abstract: The extension mechanism by means of which a table can be extended out from a cupboard comprises a multiple telescopic fitting wherein at least one of the movable telescopic guides is in the form of a double guide whose two sections together equal the length of the retracted telescope. These two sections are rigidly connected together so that they define two parallel extension lines which can be adjacent or superposed and in the extension direction are off-set relative to each other by half the length of the telescope. This means that with the telescopic fitting fully extended there is a large overlapping area within the individual telescopes which provides a more stable base for the table whilst the fitting is still able to move in and out satisfactorily. The inner extension plate of the table can be rigidly connected to the telescopic fitting so that it also moves smoothly without danger of canting.
