Title: Improvements in magnetically imageable planographic printing plates and in a method of duplicating magnetic recordings utilising said plates
IPC: B41N1/14
Filed: 1956-10-02
Abstract: 802,112. Printing surfaces. WARREN CO., S. D. Oct. 2, 1956 [Jan. 5, 1956], No. 30001/56. Class 100(2). A planographic printing plate comprises a flexible base 1, e.g. of paper, and a magnetizable coating 2 thereon, the coating 2 having a hydrophilic printing surface. In a preferred embodiment a sheet of paper is coated with a layer of liquid suspension of ferromagnetic powder and adhesive, and dried. A hydrophilic top coating 3 is then applied as a layer of aqueous composition containing hydrophilic film-forming adhesive material and a light-coloured pigment. The coated sheet is dried and smoothed as by calendering and a magnetic pattern 5 formed on the magnetizable layer in known manner. The magnetic image is developed by placing on the surface of the sheet a suspension in a volatile organic liquid of finely divided ferromagnetic powder, the particles of which have thereon a coating of potentially adhesive resinous composition. The particles are attracted to the magnetized portions but washed away from the unmagnetized areas by the liquid. The sheet is then heated to evaporate the volatile liquid and fuse the resin coating on the magnetic powder thus forming a permanently attached ink receptive planographic image. In a second embodiment the magnetizable coating is itself rendered sufficiently hydrophilic for printing purposes and in this case no further coating is applied. The base paper may include a wet strength resin such as melamine-formaldehyde condensate or may be surface sized with a solution of casein and formaldehyde. The magnetizable layer contains a hydrophilic organic adhesive such as casein, modified starch, polyvinyl alcohol or carboxymethyl cellulose as well as the magnetic powder. A satisfactory composition for the coating 3 comprises a pigment component and a suitably waterinsolubilized hydrophilic adhesive component such as insolubilized polyvinyl alcohol, carboxymethyl cellulose, and hydroxyethyl starch. Specifications 633,746, 633,747, 692,387, 766,235 and 772,112 are referred to. Reference has been directed by the Comptroller to Specification 725,142.

Abstract: 758,804. Moulding collapsible tubes &c. SLAUGHTER, C. E. Oct. 22, 1954 [Oct. 22, 1953], No. 30516/54. Class 87(2) A hot slug 1 of polyethylene, polyvinylidene chloride or nylon is clamped between a plate 2 and spring- pressed plate 4. A mandrel 9 is then moved downwardly to stretch the material into the form of a tube, a disc 14 on the mandrel shaping the end of the tube and preventing the walls of the tube from touching the mandrel, and thus preventing the walls of the tube from being cooled. When a small part of the tube has been formed, the tube is engaged by a metal die 24 which shapes the end of the tube and due to its contact with the metal causes it to set in its moulded shape. The plastic material is forced into the desired shape, which may include a screw-thread, by means of a piston 27 in the die 24. The mandrel 9 is then lowered further to form a tube of the desired length. A tube 34 is then raised, the open end of the tube blocked and air blown into the tube through a hole 37 to blow the tube into contact with the tube 34 and to set the tube in its finished shape. The tube 37 is then dropped, the die 24 removed, by unscrewing, if it is.made in one piece, and the finished tube severed at its open end from the remains of the slug. A pin 38 on the piston 27 may punch a hole in the neck 32 of the tube (Fig. 5, not shown).

Filed: 1932-10-31
Abstract: 409,718. Carburizing. DEUTSCHE EDELSTAHLWERKE AKT.-GES., Krefeld, and KRUPPA, E. F., 42, Fuchs Nordhoffstrasse, Leipsic, both in Germany. Oct. 31, 1932, No. 30661. Convention date, June 2. [Class 72.] In a process for providing a heat-stable and acid-resisting coating on articles coated with one or more carbide-forming elements of the chromium group, such as chromium, molybdenum, tungsten and uranium, the coating is wholly or partly carburized at an elevated temperature but below the melting point of the article or the layer, by exposing the coated articles to the gases produced by passing an electric discharge through an atmosphere of carbon-containing gases such as hydrocarbons. The coated articles, e.g. pistons 17 are placed in an air-tight chamber 15 which is heated and provided with a pipe 20 leading to a vacuum pump and a pipe 21 leading to a tank containing acetylene. The pipe 20 is provided with an electromagnetically controlled valve 24 and the pipe 21 with a similar valve 25, both valves being connected to contacts in the manometer casing 22. The valve 25 is thereupon closed and the valve 24 opened and the vacuum pump started up. When the pressure in the casing 15 has fallen to a predetermined limit very near an absolute vacuum, a pair of the contacts in the casing 22 is bridged over by a brush carried by the needle 22<a>, thus closing the valve 24 and opening the valve 25. Acetylene gas now passes into the chamber 15 until the pressure therein rises to about 2 atmospheres, whereupon two other contacts are bridged over by the brush on the pointer 22<a> and the sparking plugs 23 brought into the electric circuit. The gas is thereupon ignited and dissociated, and the carburization of the pistons 17 commenced. The pressure is then suddenly increased and owing to the movement of the pointer 22<a> the contacts previously bridged by the brush on the pointer are opened and two other contacts bridged, thus closing the valve 25 and opening the valve 24. When the pressure has fallen again near the absolute vacuum, the cycle of operations is repeated until the desired depth of carburization of the articles is reached. The vacuum pump is then shut off, the chamber opened and the coated pistons removed. For the treatment of hollow articles, e.g. pipes, the article itself forms the chamber 15 and covers are sealed on each end of the pipe and provided with sparking-plugs, the vacuum pipe being mounted in one cover and the gas pipe in the other.

Title: Improvements in or relating to continuous processes of forming beryllium fluoride
Inventor: JR CARL WILLY SCHWENZFEIER
IPC: C01F3/00
Filed: 1957-10-03
Abstract: Molten beryllium fluoride is continuously obtained by the decomposition of ammonium beryllium fluoride in a closed treatment chamber of a decomposition furnace heated to a temperature sufficient to maintain the resulting ammonium fluoride in the vapour state.  The beryllium fluoride is continuously withdrawn from the bottom of the furnace and the vapours of ammonium fluoride are discharged from the upper part of the furnace in a generally downward direction in a wet surface condensing and absorbing chamber from which a solution of ammonium fluoride formed therein is withdrawn. outlet from the condensing and absorbing <PICT:0814929/III/1> chamber is subjected to a suction to keep the pressure of the decomposition furnace slightly below atmospheric pressure.  As shown in the drawing the decomposition furnace comprises a crucible 2 with a dome or cover 3 provided with an inlet pipe for the admission of ammonium beryllium fluoride from a container 12. Inside the crucible 2 is provided a refractory cone 5 fitted with a central lower recess 7 into which the molten beryllium fluoride flows down the side of the cone 5 and through radial inlets in the bottom thereof.  A weir 8 is provided in the recess 7 over which the molten beryllium fluoride flows to pass to a receptacle 10. The crucible 2 is surrounded by an electric heater generally indicated at 17.  The cover 3 is provided with a discharge pipe 13 which passes to the lower chamber 20 of a condenser absorber, provided in its upper section with a packed tube 21.  Water or recycled solution of ammonium fluoride is passed down the packed section from a pipe 25 and the resulting ammonium fluoride solution is withdrawn into a container 33.  Residual vapours pass up a pipe 26 and downwardly through pipe 28 into an electrostatic precipitator 27 which is also fed with the recycled ammonium fluoride solution through pipe 36a.  A suction is applied to the electrostatic precipitator 27 and hence to the condenser absorber 21 by means of a fan 32 and connecting pipe 31.  Admission of air to the system is regulated by a damper 30 in a pipe 29 above the condenser.  In operation crushed ammonium beryllium fluoride is sent to the furnace which is maintained at about 900 DEG  C.  Molten beryllium fluoride is withdrawn from bottom and the ammonium fluoride vapour is largely condensed in the condenser 20.  The crucible 2, the cover 3 and the conduit 13 are preferably formed of graphite.
