Title: Process for preparing reactive polyacrolein alkali solution
IPC: C08G2/00
Filed: 1964-08-24
Abstract: Solutions or emulsions of polyacrolein alkali metal, alkaline earth metal, or ammonium bisulphite are prepared by reacting an aqueous emulsion of a polyacrolein with an aqueous solution of the appropriate bisulphite.  The polyacrolein may be a homo- or copolymer of acrolein which may be replaced by an a -substituted derivative. The aqueous emulsion may be prepared by homo- or copolymerization of acrolein in presence of a polyacrolein-SO2 adduct, by emulsifying acrolein or an a -substistuted derivative in an aqueous polyacrolein-SO2 solution and polymerizing using a redox-system as catalyst, or by emulsifying a precipitated polyacrolein with a polyacrolein-SO2 adduct or sodium oleate.  The reaction to form the adduct is preferably carried out at a temperature of from 50 DEG  C. to 150 DEG  C., using a molar ratio of emulsion polyacrolein to bisulphite within the range of 1:1 to 1:0.1. Specifications 797,459, 855,889 and 948,669 are referred to.

Title: Means for testing compressed air-operated valves or pistons, particularly the valvesor pistons employed in connection with the gyroscopic rudder control of torpedoes
IPC: F42B19/01
Filed: 1936-12-18
Abstract: 487,335. Testing fluid-pressure servomotor systems. MENZIES, D. N. Dec. 18, 1936, No. 34792. [Class 135] A method of testing gyroscopically controlled compressed air systems including a control valve, a relay valve and a power piston and as used, for example, for controlling the rudders of torpedoes consists in ascertaining the pressure of the air first at one end and then at the other end of the reciprocating relay valve, at the moment when the latter has reached the opposite end of its housing and varying the position assumed by the valve within its housing when at the end of its movement until subsequent pressure readings obtained are as far as possible equal. The closure plugs are removed from each end of the casing of the relay valve 1 and replaced by fittings 11 housing adjustable screw-threaded tubular members 12 adapted to serve as adjustable stops for the valve member and also to connect the operating spaces at each end of the valve with pressure gauges 19. The gyroscope cradle is slowly oscillated and readings taken at each reversal, the stops being adjusted until subsequent readings are as near as possible equal. If it proves impossible to obtain equal readings in this way, the control valve and power piston require examination. The pressure gauges may be connected by pipes directly to the actuating chambers and a single pressure gauge may be connected through a shuttle valve with the two chambers.

[Classes 83 (ii) and 83 (iv)] Uniting by fusion.- A sheet of metal clad with another metal is secured to another metallic surface by two different weld metals, the inner of which is a metal for welding the surface to the inner layer of the covering sheet and the outer of which is of approximately the same composition as the outer layer of the covering sheet. A drum for use in chemical processes or in oil distillation and composed of carbon steel may thus be lined with a compound corrosion-resisting coating, the inner layer of which consists of carbon steel and the outer layer consisting of steel containing 12-18 per cent of chromilun or 18 per cent of chromium and 8 per cent of nickel or consisting of nickel. A number of lining sheets may be inserted into the drum and welded thereto through circular or other holes in the sheets and also along their abutting edges. In the carbon steel shell 1 are placed the sections of the compound liner consisting of a carbon steel sheet 2 united to a chromium steel &c. sheet 3 and welding is effected by first applying carbon steel through tapered holes as at 6 to weld the parts 1 and 2 together and then applying at 7 in one or more layers weld metal of substantially the same composition as that of the sheet 3 or containing a slightly greater percentage of chromium &c, so that the resultant joint is of the same composition as the sheet 3. The welding metal 7 may overlap the edges of the holes. The edge jointing is similarly effected.
