Title: Concrete with very high strength, prodn - by autoclave treatment which may be followed by a drying treatment at high temp
Inventor: POLLET HENRI
IPC: C04B28/02
Filed: 1974-05-20
Abstract: High-strength concrete is mfd. by making a conventional concrete from coarse and medium aggregate, a very fine or milled sand and cement, and then subjecting it to thermal treatment in an autoclave at 200 degrees C/16 atmos. The sand may be replaced by clay puddle, previously dried and powdered, whereas the cement may be partly or completely replaced by lime. A second thermal treatment may be used in a dry stove at 350 degrees C to obtain a further increase in strength, esp. followed by surface impregnation so that the dry material does not absorb water. Impregnation is pref. undertaken with a synthetic resin with polymerisation under a pressure of nitrogen (100 atmos.). The thermal treatment doubles the strength, and, if the second treatment is also used, the strength is tripled.
Patent FR-2270997-A1 (FR)
Title: Detachable blade screwdriver with inclinable handle - is rotated by radial lever with locking device for handle
IPC: B25B15/04
Filed: 1974-05-17
Abstract: The tool holder receives screwdriver blades, box spanner bits or other tools functioning rotationally and has an articulating junction between the handle and the mandrel body so that the handle may be locked at a desired inclination. The tool holder may thus be used in situation inaccessible to conventional screwdrivers etc. The tool mandrel is rotated by a hand lever emanating radially from the longitudinal axis of the mandrel, rotation without disengaging the bit from a screw being obtained by a ratchet mechanism. Alternatively a lockable crown-wheel and pinion connection from lever to mandrel can be utilized so lever rotation about its own long axis effects bit rotation.

Title: Re-orientation of weld zones in polyester shrink wrap bags - by localised heating and inflation to re-draw weak material alongside the weld
IPC: B31B50/64
Filed: 1975-06-27
Abstract: Enhancing the strength of welded seams in bags or sacks made from biaxially oriented polyester film, involves inflating the sack while confining it between platens except for preferentially heated zones adjacent to the weld line, thus allowing localised post drawing and orientation to restrengthen annealled material adjacent to the weld. Automated equipment for locating a succession of individual bags between suitable platens, opening the bag mouth to an inflation nozzle and applying a controlled heat flux to the base weld region. Method is used for prefabricated packaging, esp. for shrink wrapping irregular goods, e.g. poultry. It reduces the risk of preferential weld failure due to general or localised stresses, i.e. can reduce chicken pack rejection on drop handling tests from 3-5% to 1%.
