Inventor: HEINO AARNE JUHO HENRIK
IPC: F16L9/12
Filed: 2010-11-16
Abstract: The object of the invention is a method to produce plastic pipe where a pipe of two or more layers (1,2,3) is extruded and where at least one layer (1,3) has additive that by heat treatment releases free radicals. Immediately after the extrusion, the pipe is heat treated by leading it either through a hot salt bath or an infra red radiation so that the mentioned additive decomposes. Now, the layer(s) (1,3) having additive get cross-linked and additionally the cross-linked layer(s) (1,3) fix with chemical bonds to at least one other layer (2).  With this method it is possible to produce a plastic pipe where there is no need to use a separate adhesion plastic layer to fix to each other layers that reject each other.

A text cell, for determining the throwing power of a plating bath is shown Fig. 1 (not shown), divided by partitions 6 having holes 10 drilled therein, and having cathode panels 2, 4 and an anode 8, the throw being calculated from the weights of metal deposited.

Abstract: 1,239,479. 1α,2α - Methylene - steroids. SCHERING A.G. 19 -July, 1968 [19 July, 1967], No. 34548/68. Heading C2U. Novel racemic and optically active steroids of the. formula (wherein R is H or a hydrocarbon group and R<SP>1</SP> is H or acyl) are prepared by -introducing a double bond into the 4,5-position of corresponding ring A-saturated steroids. The introduction is effected by. known methods, e.g. a 3-ketosteroid is converted to a 3-enol ester and this is brominated then dehydrobrominated. Resulting 17-ols may be acylated and 17-acylates hydrolysed. 17# - Acetoxy - 18 - methyl - 1α,2α - methylene- 5α-estran-3-one is prepared by reducing 17#- hydroxy - 18 - methyl - 4 - estren - 3 - one to give 17# - hydroxy - 18 - methyl - 5α - estran - 3- one (and the corresponding 3#,17#-diol, which, alone or in admixture with the 3-one, can be oxidized to the 3,17-dione, this converted to 3,3- dimethoxy - 18 - methyl - 5α - estran - 17 - one and this reduced and hydrolysed to give more of the required 17#-ol-3-one), this is converted to the 17-acetoxy compound, this is brominated and dehydrobrominated to give 17#-acetoxy-18- methyl-5α-estr-1-en-3-one and this is converted to the required product. All the foregoing compounds are racemates. The d-enantiomers are prepared similarly; hydrolysis of the final product gives 17# - hydroxy - 18 - methyl - 1α,2α- methylene-5α-estran-3-one and this on esterification gives the 17-propionyloxy compound. The novel anabolic steroids may be made up into pharmaceutical compositions with suitable carriers.

Abstract: 1,251,696. Dibenzothiepin derivative. J. R. GEIGY A.G. 20 Feb., 1969 [21 Feb., 1968; 31 Jan., 1969], No. 9141/69. Heading C2C. The novel compound, 8-chloro-10-(l-piperazinyl) - 10,11 - dihydro - dibenzo[b,f] - thiepin, of Formula I and its pharmaceutically acceptable acid addition salts, are prepared by hydrolysing a compound of the Formula II in which Y represents a radical which can be replaced by hydrogen by means of hydrolysis, e.g. a carbalkoxy radical, and optionally converting the reaction product into a pharmaceutically acceptable acid addition salt. 4 - (8 - Chloro - 10,11 - dihydro - dibenzo[b,f] thiepin - 10 - yl) - 1 - piperazine carboxylic acid ethyl ester is prepared by reacting 8,10-dichloro- 10,11 - dihydro - dibenzo[b,f] thiepin with 1- piperazine carboxylic acid ethyl ester. Pharmaceutical compositions, having a central depressant and anti-emetic activity, for oral, rectal or parenteral activity, comprise the compound of Formula I, or a pharmaceutically acceptable acid addition salt thereof, together with a pharmaceutically acceptable carrier.

Abstract: 1,251,930. Joining structural members. VEREINIGTE ALUMINIUM-WERKE A.G. 29 May, 1970 [30 May, 1969], No. 26020/70. Heading E1K. [Also in Division F2] A member 2 is connected to a hollow member 1 into which it extends via an aperture 3, by a resilient U-shaped clip 5 within the member 1, the limbs of the clip having inturned ends which engage recesses 4 in opposite sides of the member 2, the end of the member 2 lying within the clip. The members 1, 2 may both be tubes of any required cross-section, the clip 5 closing the end of member 2, and the aperture 4 preferably corresponding in shape to the section of the member 2. Lugs 6 on the inturned ends of the clip stabilise the member 2. The connection is applicable to railings, grid facades, or ventilator gratings in air-conditioning plants.
