Title: Improvements in or relating to copy-holders for typewriting and like purposes
IPC: B41J29/15
Filed: 1921-05-06
Abstract: 170,823. Didier des Gachons, L. Oct. 23, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Copy-holders.-In a copy-holder provided with a line-indicating ruler, a lever for adjusting the ruler is mounted on the sliding support of the ruler and has a wedging action on the guiderod of the support. To the back of the plate 1 of the device is hinged a rod 2 slidable in a bass member which may be sufficiently heavy to provide the necessary steadiness, or may be inserted beneath the foot of a typewriter. A spring clamping-member 3 provided with elastic buffers 4, holds the copy in position. A ruler 6 is carried by support 8 which is adapted to slide on a guide-rod 7 secured to one side of the plate 1. The support 8 is provided with an operating-handle 9, and another handle 10 movable relatively to the ruler-support on the rod 7, is normally held against the lower wall of the support, by a spring 11, Fig. 3. To move the ruler downwardly, the handles 9, 10 are pressed together, the handle 10 thereby swinging and becoming wedged on the rod 7 and the handle 9, together with the support 8 being caused to slide - on the rod. On pressure being released, the handle 9 retains its adjusted position by reason of its frictional engagement with the rod 7, and the handle 10 is forced down into its initial relative position by the spring 11 or by gravity. In the modification shown in Fig. 4, the ruler is supported on a cage 14, slidable on the rod 7 and is provided with a lever 12 pivoted thereto at 13. A spring 16 normally causes a member 15 to wedge on the rod 7. Sliding in a slot in the base of the cage is the vertical side of a member 17 which is held to the base of the cage by a rod 18 and is adapted to swing thereon, a spring 19 normally tending to keep the two parts separated. When the lever 12 is depressed, the member 15 is swung upwardly and wedged on the rod 7 and so acts as an abutment for the inner end of the lever 12 which slides thereon and draws the cage down. When the pressure is released the member 17 swings and wedges on the guide-rod to prevent the cage being drawn back and the spring 16 forces the member 15 and lever 12 into their original relative positions. A set-screw 21 may be provided to limit the downward movement. To move the ruler upwards, the lever 12 is raised slightly and causes the members 15, 17 to assume a position perpendicular to the. rod 7, so removing the wedging action, the oblique position being resumed on release of the pressure.

Patent GB-914458-A (GB)
Title: Process for separating metals
IPC: C30B13/00
Filed: 1961-04-11
Abstract: Metals which are not completely miscible in the liquid state are separated by cooling successive layers of a molten mixture of the metals in the direction of the gravitational force on the mixture to freeze one of the metals and allow the other metal to drain into the lowest layer.  The process is particularly applicable to the purification of Zn contaminated with Pb in which case the resultant ingot consists of Pb in the lowest layer and Zn in the remaining layers.  The process may also be used for the removal of Pb from Zn alloys.  A portion only of each layer may be cooled as above, the remainder of the melt being cooled as a whole so that the resultant ingot consists partly of pure and partly of impure material.  The mould containing the molten material should be either of uniform cross-section or larger at the bottom than the top.  The cooling may be effected by movable cooling elements, spraying a volatile liquid on the outside of the mould or internal cooling elements.ALSO:Metals which are not completely miscible in the liquid state are separated by cooling successive layers of a molten mixture of the metals in the direction of the gravitational force on the mixture to freeze one of the metals and allow the other metal to drain into the lowest layer.

Patent GB-132042-A (GB)
IPC: C07C51/00
Abstract: 132,042. Compagnie des Produits Chimiques d'Alais et de la Camargue. May 4. 1918, [Convention date]. Chloracetic acid.-The production of chloracetic acid by the reaction of hot sulphuric acid upon trichlorethylene is rendered continuous by continuously supplying water to maintain the sulphuric acid at the proper concentration (about 90 per cent.) and removing the chloracetic acid as formed by means of an excess of trichlorethylene vapour. In the apparatus shown, trichlorethylene vapour from a boiler A bubbles through sulphuric acid in the vessel D; the escaping vapours (trichlorethylene, chloracetic acid, steam) and hydrochloric acid gas pass off by pipe F to a reflux condenser G; the condensate flows to the decanting- vessel M, where it separates into aqueous chloracetic acid which flows into vessel N and a mixture of chloracetic acid and trichlorethylene which is returned to the boiler A. The contents of the vessel N are added to the vessel O which continuously supplies water to the vessel D. The chloracetic acid flows off from the boiler A to a similar boiler S in which it is further freed from trichlorethylene, and passes to a container U. From the reflux condenser G the escaping hydrochloric acid gas passes to a tower I in which it is washed with cold trichlorethylene to free it from chloracetic acid, and then passes to a second tower K in which it is condensed by cold water, the resulting liquid flowing to a decanting-vessel L in which the trichlorethylene is separated from the aqueous hydrochloric acid. The tower I is fed with trichlorethylene from a vessel Y and also from a condenser X which leads from a branch V of the pipe B. The reaction is carried out at 160-190‹ C. Specification 129,301 is referred to.
