Title: Hollow concrete soil foundation pile - is formed by driving concentric pipes and pouring concrete between them during extraction
IPC: E02D5/42
Filed: 1975-05-02
Abstract: The hollow cylindrical concrete pile body is relatively thin-walled. Two concentric pipes (1, 2) on an annular footplate (7) with distance pieces (8) between them are driven into the ground by means of an impact cap (5) gripping them at the top. Concrete is then poured in between the pipes via a chamber formed at the upper end of the inner pipe above a barrier over the central hole (12) and through openings (14) in the inner pipe. At the same time the pipes, held together by the cap, are extracted, and the concrete flows into the annular space formed.

Title: Operation of drum-type electroplating appts. - by periodic drum rotation reversals to increase article residence time
IPC: C25D17/20
Filed: 1982-11-12
Abstract: The parent patent describes an electroplating appts. consisting of an electrolyte-contg. vessel in which an electroplating drum is arranged, the drum comprising an open-ended cylinder which is rotatable about its longitudinal axis and which contains guides for moving articles through the drum from its inlet end to its outlet end. In this addn. the drum is continuously filled with articles only to part of its length and the articles are moved back and forwards one or more times by reversing the rotational direction of the drum before the articles are passed to the drum outlet. The appts. is esp. useful for electro-deposition of aluminium from oxygen-free, anhydrous organic electrolytes onto small articles. The residence time of the articles in the drum can be increased to obtain the desired plating thickness, while operating at the optimum drum rotation rate and current density, without increasing the drum length.

Patent PT-72958-A (PT)
IPC: A23L13/30
Filed: 1981-04-30
Abstract: The material for extraction is extracted with physiologically acceptable fat or fat-like solvents in the presence of water. This is carried out in a closed pressure vessel at elevated temperature. The amount of water must be such that the water activity corresponds to a aw value of not less than 0.5. By suitable choice of the aw value it is possible to control the process in such a way that the flavour develops in the direction of a boiled flavour or in the direction of a roast flavour. The resulting flavour concentrate can be used as a semi-finished product in the manufacture of sauces, soups, seasoning mixes and the like or can be sold as a finished product. The material which has been subjected to the extraction process is in general completely tasteless.

Abstract: A method of making a porous polymeric material by heating a mixture of a thermoplastic polymer and a cationic or non-ionic surfactant having a hydrophilic-lipophilic balance range of 4.0 to 6.0 to a temperature and for a time sufficient for the polymer and surfactant to mutually dissolve. The mixture is then cooled to a temperature so that non-equilibrium liquid-liquid phase separation takes place to form a bi-continuous matrix of the polymer and surfactant so that the polymer and surfactant form two intermingled separate phases of large interfacial surface area. The surfactant is then removed from the polymer. The porous polymeric material produced by the above method has a lacey or filamentous structure consisting of a plurality of polymer strands connected together at spaced apart locations along each strand.
