Title: Removing drawing lubricants from copper tubes before annealing - by alternately blowing into the bores a degreasant and steam
Inventor: JANSSEN ROBERT
IPC: C23G5/00
Filed: 1973-07-20
Abstract: The process is designed to remove drawing and working lubricants remaining in the bores of tubes which require annealing. If the lubricant is not removed prior to heating, carbon is formed in the tube-bores and is a major cause of the corrosion of copper in water-distribution systems used in sanitary installations. The novelty is that, prior to annealing, the tubes are injected with steam to which precise amts. of a degreasant have been added one or more times. The pref. degreasants are trichloroethylene or tetrachloroethylene. The pref. method consists of alternate injections of degreasant and steam under press., followed by compressed air, and finally the protective gas, outside the annealing furnace.

IPC: B29C45/00
Filed: 1973-11-06
Abstract: An injection moulding machine, for simultaneously extruding a smooth outer skin matl. and a porous core matl. as in parent patent, comprises an injection barrel with associated plasticiser for the skin matl. and an additional piston-cylinder unit with a sliding nozzle coaxially mounted for producing the core matl., and is useful when both matls. are plasticised ca. same temp, and heat transfer between them is not important. The method is improved in that the piston-cylinder unit can be moved back coaxially from the injection barrel which produces the skin matl., so that there is no thermal contact between them, and can be advanced into the injection barrel; the injection barrel contg. an intermediate piston having an axial passage through it, through which the nozzle of the piston-cylinder unit can be brought forward when the core matl. is to be injected. When the piston-cylinder unit is not being applied to the rear of this intermediate piston, the latter can be driven forward by an additional pressure mechanism. The central axial passage through the intermediate piston can, in addn., be closed, esp. by a closure valve which is automatically opened when the sliding nozzle is advanced through the passage. The method is suitable e.g., for a moulding with a thermoset cone and thermoplastics skin.

Patent DE-2419932-A1 (DE)
Title: Microcellular matl mfr with selective distribution of cavities - by controlled addn of blowing agent in minimal quantities
Inventor: HILLESHEIM HANS
IPC: C08J5/12
Filed: 1974-04-25
Abstract: Micro-cells are produced in working material by ad-mixtures of minor amounts of blowing agents so that exceedingly small cavities are formed at the surface and in the interior of the prod. The cell need not be uniformly distributed throughout the matrix. Hence, if they are concentrated e.g. at the surface then the process as claimed may be considered as surface treatment of the matrix. The later may be a film (e.g. polyolefin) and the superficial cells may be used for anchoring printed indicia. As a result, conventional surface ("subbing") treatment such as by electrical discharge, may be dispensed with.

Title: Container closure proof against operation by children - two different types of movement must be applied either simultaneously or successively
Inventor: BREHM GEB EHRMUTH HEIDE
IPC: B65D50/04
Filed: 1974-05-11
Abstract: The closure and safety mechanism form a coherent unit whereby the safety mechanism can be coupled - e.g. engaged or stuck - as an auxiliary element (e.g. 6) with the container. No additional means, e.g. a key or opener, are required in order to operate the mechanism whereby when closing the container only one type of movement is necessary e.g. pressure or rotation. In this way the closure and safety mechanism can be used with a wide variety of container fastenings. In one design, opening the container requirs a thrust-rotation-pull combination of movements whereby a horizontal displacement of the securing element (6) releases hook-like undercuts (5).
