Title: Autographic register
IPC: B42D19/00
Filed: 1964-06-17
Abstract: 1,049,244. Autographic registers. J. LESKOVEC. June 17, 1964, No. 25042/64. Heading B6A. . In an autographic register the web of writing paper 14 is line-spaced automatically, when the writing hand has reached the end of a line, by the engagement of the hand with a bar 35 or other means which is displaced sideways by the hand. Two modifications are described, that shown in Fig. 1 employing a web which is unwound from one roller by a mechanical drive, and rewound on another by a known roll winding mechanism, and that shown in Fig. 19 employing a web drawn optionally from a zigzag folded stack by either a mechanical drive or a drive operated electromagnetically and restacked in zig-zag folded manner. Fig. 1 shows a register 10 having an arm rest 12 supported on legs, and an elbow rest 17 which may be adjustable towards and away from the register. A writing platen is supported within an aperture 13 in the top 11 of the register, and paper 14 is drawn from a roll over the platen and passes between a feed roller and an idler roller to a take-up spool which is rotated as required by known means. The feed roller and its drive are identical with those shown in Fig. 19, which is an under plan view. Two upright guides 15, 16 are arranged on the top 11, and the bar 35 is hinged to the bar 16 at one end and urged resiliently away therefrom, and is pivotally connected at its free end to a shaft 33, Fig. 19, which is axially slidable but not rotatable. A shaft 47, which can be rotated by a knob 57, is connected to the shaft 33 and has three racks 49, 50, 51 thereon, one of the racks engaging a gear on a shaft 60. The shaft 60 is coupled to the paper feed roller 72 through bevel gears 67, 68, so that the paper 14 is fed each time the writing hand moves the bar 35 towards the guide 16. The racks 49, 50, 51 are of different lengths and are selected by turning the knob 57 to vary the length of feed of the paper 14, as desired. In Fig. 19 the feed roller 72 can also be driven by one of three racks 109, 110, 111 of different lengths, which can be moved by a slide 116 to engage a gear 113 on the roller 72, and the operative rack is pushed forward by a plunger 107 in a solenoid 106 which is energized by a switch 44 when the bar 35 has been moved by the writing hand. The front portion of the register is hinged to the main body, and can be swung away therefrom on the operation of a lever 102, whereby the bevel gear 68 of the feed roller 72 is disengaged from the gear 67 of the mechanical drive, and is then operative by the electromagnetic drive. The paper web fed by the roller 72 and an idler roller is stored in a zig-zag folded stack in a drawer slidable in the front wall 108. Marking means.-Three pens 89, which can draw vertical lines in coloured inks on the moving paper web 14, are each coupled to one of three depressible keys 76 to mark the web, and the keys can only be released when a cancelling key 92 is depressed. The selected key 76 will cause a line to be drawn on the web to indicate particular matter written on the web opposite thereto.

Title: Process for the production of pure aluminium-silicon alloys
IPC: C22C21/02
Filed: 1933-09-14
Abstract: In a process for the production of aluminium-silicon alloys, an aluminium-silicon pre-alloy relatively high in silicon is freed from contained impurities by fusion with substances such as fluorides, chlorides &c., then separated from the saline melt, and combined with aluminium, the saline melt being continuously regenerated by electrolysis and used again for refining further quantities of the pre-alloy.  The refining of the pre-alloy may be combined with the regeneration of the saline bath by using the pre-alloy as cathode in the saline bath, the anode being either a material insoluble in the bath such as carbon or the pre-alloy itself.  Aluminium oxide in the electrolyte is decomposed, aluminium being deposited on the cathode, and impurities such as carbon in the melt are burnt at the anode, or separate out on the surface of the bath.  Undissolved impurites in the pre-alloys may be eliminated, prior to refining, by filtration through beds of granular material such as quartz or aluminium oxide.
