Title: Apparatus and method for the continuous production of aqueous polymer solutions
Inventor: LUETZELSCHWAB WAYNE E
IPC: C08F8/12
Filed: 1983-07-11
Abstract: Apparatus and method for the continuous preparation of dilute solutions of water soluble polymers, and especially a closed, on-site arrangement for the continuous production of partially hydrolyzed polyacrylamide solutions for use in the secondary and tertiary recovery of oil from subterranean, oil-bearing reservoirs. The apparatus, in its preferred form, comprises an in-line system which includes a polymerization reactor, a hydrolysis reactor and a diluter. The dimensions of the reactors are such that the reactions taking place therein will go to completion as the reaction mixtures move from the inlet to the outlet of the reactors. Drag means advantageously are positioned in the reactors to control the flow rate of the reaction mixtures and to promote intermixing of the reactants. The diluter of the system incorporates a plurality of polymer dispersing stations which act to progressively increase the water absorbing surface area of the polymer as the polymer solution passes through each station. The diluted end product is characterized by its ability to meet the performance demands of substantially any oil-bearing formation.

Title: Swimming pool construction
Inventor: BURNELL RICHARD MICHAEL
IPC: E04B2/86
Filed: 1984-12-21
Abstract: In order to provide an improved method of constructing a swimming pool wall by casting concrete into shuttering assembled on site from modular components, the shuttering is built up from elements comprising inner and outer slabs or blocks (11, 12) assembled together in a predetermined spaced relationship, and in which at least an external face of the shuttering is formed by the outer slabs which are of a thermally insulating foamed plastics material, preferably a high density polystyrene. The outer slabs are left in situ after pouring of the concrete to provide thermal insulation, while the inner slabs are removed after pouring and setting of the concrete, and may be disposed outside the outer slabs prior to back-filling the cavity outside the outer slabs. The slabs of each element are held together in spaced relationship by tie bars (13) of plastics material. Adjacent edges of the shuttering may have cooperating projections and recesses to allow angular movement without detriment to the seal between the edges. The invention also comprehends the shuttering itself. <IMAGE>

Title: Manufacture of tubes
Inventor: QUAMBUSCH ALBERT
IPC: B21B19/06
Filed: 1986-10-08
Abstract: In the manufacture of seamless tubes, a billet is heated to rolling temperature, is pierced in a skew rolling stand 7, is stretched into a tubular bloom in a transverse rolling line 14 and rolled out into a finished tube in a finish-rolling line 15. The stretching of the hollow billet into a tubular bloom is carried out in several stages, these stages being carried out simultaneously on the same hollow billet using a transverse rolling method. To do this, the transverse rolling mill 14 does not require a reheating furnace upstream of the finish-rolling process and, with the aid of a rolling-block-type arrangement of a plurality of exchangeable transverse rolling stands, permits particularly large stretching or cross-sectional reduction as entry of the tubular bloom into the finish-rolling line 15 which is disposed at a short distance directly therebeyond. <IMAGE>
