Title: Improvements in and relating to a process for the electro-deposition of a waterborne paint
Inventor: WALLACE JOHN FREDERICK
IPC: C25D13/22
Filed: 1963-05-01
Abstract: In a process for the electrodeposition of a water-borne paint on an electrically conductive surface of an article, the article is partially immersed in a coating medium, and, whilst the coating is deposited, the article is rotated so that each part of the surface is repeatedly and successively immersed in and withdrawn from the medium.  The examples are of electro-depositing a water-borne paint comprising an alkyd water soluble resin pigmented with a red iron oxide and having a pH of 7.9.  The article was rotated twice with an applied potential of 60 volts. The time per revolution and temperature of the paint were, in Example I, 45 secs. and 30  DEG C. and, in Example II, 30 secs. and 35  DEG C.  In both examples, a paint coating of 5.5 mg. per sq.cm. was deposited.

Abstract: 384,586. Aerating liquids. ZIMMER, L., 36, Niedenau, Frankfort-on-Main, Germany. June 21, 1932, No. 17527. [Class 14 (i).] The contents of bottles are aerated by gas under pressure from pipes 8, 6 when the case 1 containing them is in the inverted position. The bottles are forced up against packing 2 on the underside of a cover 3, which has openings 4 communicating with the pipes 6. The bottles have ball closures which serve to break up the stream of gas as it enters. When the aeration is complete, a three-way cock 9 is turned to cut off the supply of gas and open the pipes 6, 7 to the atmosphere. The balls thereupon fall and close the bottles, which are removed on lowering the screws 15 and folding down one of the sides of the case. Check valves are fitted in the pipe connections 5. In a modified construction, Fig. 3, the bottles are inserted through holes in the bottom. These have hinged cup-shaped closing flaps 34 which contain springs 37 to press the bottles against packing 31. Metal cases 32 guide the bottles to the packing. All joints are made watertight so that ice may be packed round the bottles.

Title: Improvements in or relating to arc welding systems
IPC: B23K9/073
Filed: 1939-06-20
Abstract: 530,177. Automatic control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 20, 1939, No. 17929. Convention date, June 24, 1938. [Class 38 (iv)] Arcs. - An arrangement for controlling the feed of a fusible electrode 18 in an A.C. arc welding system comprises a reversible D.C. motor 24 the armature current of which is controlled in direction and magnitude by means, including a undirectional conducting device 56, operating in accordance with the voltage across the arc electrodes. The means comprise a generator 28 driven by a motor 30 supplied from a constant voltage generator 34 which also supplies current to the field of the motor 24 and to resistances 35, 36, 37 in series therewith. The generator 28 feeds the armature of the motor 24 in opposition to the voltage drop across resistance 37, and its field excitation is effected in accordance with the difference between the voltage drop across resistance 35 and the voltage at the D.C. terminals of the rectifier 56 so long as the latter predominates. Thus, on closure of switches 17, 42, 64 following depression of push-button 59, the generator 28 is fully excited and the motor 24 starts in a direction causing the fusible electrode to be fed forward into contact with the work 20. The resulting fall in voltage at the terminals of the rectifier 56 decreases the excitation of the generator 28, the voltage of which falls below that across resistance 37 whereupon the motor 24 reverses and causes the arc to be struck. The electrode feed is thereafter automatically regulated by control of the excitation of the generator 28 in accordance with the voltage at the terminals of the rectifier 56. In a modification, the reversible voltage applied to the armature of the motor 24 is obtained directly from the terminals of the generator 28 which is provided with two opposed field windings.

In the presence of reagents viz. sodium ethyl xanthate and methyl isobutyl carbinol, froth mounts in the tank and overflows over launders 21. Pulp is discharged via an opening 15 and pipe 16. Drainage is effected through normally closed holes 22. Deenergization of the jet may also be effected by its impingement on the opposite tank wall, or by opposing pulp/air jets, or by mounting the jet on the bottom of the tank, or directing it downwards. In these cases the pulp may be deaerated in and discharged from another tank. In a second embodiment a pulp discharge slot 29, Fig. 7 and weir 31 are provided.

A continuously fed web is stopped intermittently at a treating zone situated between rollers 7 and 9. Rollers 6 and 7 are nip rollers and the shaft of roller 7 is connected to a pneumatically operated disc brake to stop the web. Two looping rollers 18 and 19, fixed relative to each other on a member 17, Fig. 1 (not shown), allow the web to be fed continuously to the apparatus when the web is stopped in the treating zone. A two-way pneumatic cylinder 11, Fig. 1 (not shown), biases the rollers 18 and 19 to the left in Fig. 2 when the web is advancing through the treating zone. When the web is halted in the treating zone by operating the disc brake on roller 7, air is fed to both ends of the pneumatic cylinder 11 to substantially equalize the air pressure, so that the rollers 18 and 19 are drawn to the right by the pull of the web on roller 19, thereby increasing the length of web travel entering the treating zone and decreasing the length of web travel leaving the treating zone.
