Title: Improvements in or connected with water-waste preventers
IPC: E03D1/14
Filed: 1934-02-24
Abstract: 438,878. Siphondischarge waterwaste-preventers. MARSHMAN, G., and MARSHMAN, M. K., 4, Halvard Street, Bury. Feb. 24, 1934, No. 6075. [Class 26] In order that flushes of varying magnitude may be delivered, a siphon-discharge waterwaste-preventer is provided with a chamber 27 surrounding the siphon and formed by a wall 30 mounted on a base 34 which is formed with a hole to receive the long leg of the siphon so that the mounting of the siphon also serves to secure the base in position ; the arrangement is such that normally only the water above the level of and within the chamber is discharged, but that when the wall is moved, or a valve associated with an opening in the wall is lifted, the whole of the cistern-contents are discharged. The quantity discharged may be further varied by the provision of an adjustable sill in the chamber-wall or by slots covered as desired by an adjustable plate or plates. The movement of the wall 30 is produced by a lever 38 which causes the wall to tilt about a hinge 36 by which it is attached to the base, the roof of the cylinder may have a cup 45 to prevent premature entrance of air. Specification 438,591 is referred to.
Patent GB-232560-A (GB)
Title: Process for drying calcium hypochlorite compounds
IPC: C01B11/06
Filed: 1925-03-06
Abstract: Calcium hypochlorite is dried by first subjecting it to a heat treatment with or without reduced pressure to effect a preliminary drying and then combining the remaining water by the addition of oxides or salts which readily unite with water, e.g. quicklime. Preferably the drying agent is added while the hypochlorite is still hot.  As the water content of the latter is largely reduced during the heat treatment, little drying agent is required and the content of available chlorine is consequently only slightly affected.  Basic calcium hypochlorite compounds besides the normal salt may be dried as above described.

Filed: 1944-04-05
Abstract: 568,996. Photographic shutters. KODAK, Ltd. April 5, 1944, No. 6367. Convention date, May 4, 1943. [Class 98 (i)] A shutter of the type in which a pair of pivotally-mounted blades are movable in opposite directions to open and close the exposure aperture through movement of a master member which is tensioned and released during depression of a shutter trigger, is provided with a single blade-operating pin carried by one blade and operatively engaging the other blade, and the master member carries a spring cam which wipes past the pin during the tensioning movement of the master member, but which during movement of the latter in the opposite direction moves the pin in a direction to open the shutter blades. As shown in Figs. 1 and 5, the mechanism is mounted within a casing having a bottom wall 2 with a central exposure aperture 3 and an upstanding flange 4. The mechanism is mounted on a plate 5 attached by screws 6 to the plate 2, and a shutter cover may be provided. The shutter blades 7 are mounted on pivots 8, and one blade 7 carries a pin 9 extending through a slot 10 in the other blade and through a slot 10<1> in the plate 5. The master member 11 pivoted at 12 to the plate 5 is normally held against a lug 14 by the spring 13. The end 15 of member 11 is bent to form a flange 16 provided with a cam surface 17 on the extreme end, a cut-out 18 intermediate its ends, and a bevelled surface 19 at the end remote from cam surface 17. An upwardly extending end 20 of the cam surface 17 co-operates with the adjacent edge of member 11 to limit movement of the flange 16 towards the exposure aperture 3. Downward movement of the trigger 21, normally urged upwardly by spring 23, causes arm 24 to move member 11, the cam surface 17 springing over the pin 9. The arm 24 then rides off the bevelled surface 19 and the member 11 is returned by the spring 13. The cam surface 17 strikes the pin 9 and causes it to move radially to open the blades 7, the blades being held open until the pin 9 reaches the cut-out 18, when the pin 9 is moved by spring 25 through the cut-out and the blades close. The spring 23 returns trigger 21 to its initial position and towards the end of the movement, the bevelled surface 26 of the trigger rides under the bevelled surface 19 until it engages the end of the cut-out portion 18. The time of exposure is determined by the length of the flange part 17 the slope of the cam surface 17, the speed of member 11 and the strength of spring 25.

Title: Improvements in and relating to the distillation of normally solid substances
IPC: B01D7/00
Filed: 1929-03-04
Abstract: 324,840. James, R. W., (National Aniline & Chemical Co., Inc.). March 4, 1929. Distilling plant and processes; hydrocarbons, distilling. - In the vacuum distillation of normally solid materials such as naphthalene, phthalic anhydride, anthracene and betanaphthol, the vapours are condensed to the liquid state and the vacuum is maintained by withdrawing jointly with a wet vacuum pump the uncondensed gases and the liquid condensate or an auxiliary liquid. Solid material vaporized in a still 1 is liquefied in a condenser 6 and is delivered, at a temperature regulated by a cooler 10 to a wet vacuum pump 12. The latter is preferably a rotary positive displacement pump with a liquid seal, and is operated at a temperature such that the condensate acts as the sealing liquid. The pump delivers to a separating chamber 14, from which the gases escape by a pipe 17 while the condensed liquid collects in a reservoir 16. By using a pump of suitable size, 'the pressure in the system is automatically regulated by the rate of condensation of the product. In a modification, Fig. 2, condensate passes directly from a cooler 28 to a separator 30 and thence to an evacuated reservoir 32. The pump 36 operates with an auxiliary sealing liquid which passes from a reservoir 41 by a cock 43 and mixes with the uncondensed gases coming from the pipe 35; the mixture is exhausted to a separator 38 from which the gases escape by a pipo 39, while the liquid is returned to the reservoir 41. The liquid used is preferably a solvent for the material distilled, so as to prevent escape of the latter with the exhaust gases; its vapour pressure should be low, and when corrosive substances are being distilled the sealing liquid may react with and neutralize any traces carried over with the gases. The sealing liquid is not necessarily circulated in a closed cycle, and may be treated for recovery of the dissolved material.

Title: Improvements in or relating to the production of magnesium alloys
Inventor: BALL CHARLES JAMES PRIOR
IPC: C22C1/02
Filed: 1946-01-31
Abstract: A master alloy, for use in the production of magnesium base alloys containing zirconium, comprises at least the following three phases: (1) a metallic matrix phase consisting mainly of magnesium and/or one or more "permissible elements" and having zirconium dissolved therein; (2) a metallic phase consisting mainly or wholly of zirconium in readily alloyable form and (3) a salt phase in quantity between 1 and 30 per cent of the whole and consisting mainly or wholly of one or more halides inert to molten magnesium; the master alloy being substantially free from "zirconium alloying inhibitor elements" and containing at least three per cent zirconium.  The "permissible elements" are defined in the Specification as elements which are incapable of combining with the zirconium dissolved in magnesium to form high melting point compounds which settle out. Among such elements are zinc, cadmium, cerium, silver, thallium, thorium, copper, bismuth, beryllium, lead, calcium.  "Zirconium alloying inhibitor elements" are elements which do form such high melting point compounds.  The master alloy may be made by mixing an excess of molten magnesium with a molten or prefused substance consisting of a zirconium halide with or without other suitable halides under conditions permitting reduction of the zirconium halide to produce metallic zirconium but incapable of permitting any substantial incorporation of zirconium in the excess magnesium which is poured off.  The said substance may consist solely of fluorides. The mixing may take place in vacuo or in an inert atmosphere.  A magnesium-base alloy may be produced by introducing the master alloy into molten magnesium and agitating it therein.  Specifications 511,137, 511,482, 533,264, 652,223, 652,230 and 26438/39 (as open to inspection under Sect. 91) are referred to.

Abstract: 705,464. Copy-turning; milling ; planing. CINCINNATI MILLING MACHINE CO. March 21, 1952 [March 23, 1951], No. 7343/52. Class 83 (3). [Also in Group XXIX] A copying machine, such as a lathe or a planing or milling machine has means for imparting to the tool slide a sensitive initial movement for compensating for the deflection of the tracer required to initiate the copying movement. As applied to a lathe, a. main slide 27 is operated' by a main piston 33 under the control of a spool 65 on a spring-loaded tracer-valve 47 within a body 43 on the main slide, and an auxiliary tool-carryirig slide 39 on the main . slide is operated by an auxiliary piston 37 under the control of a spool 80 on the tracer-valve. Two bushings are fitted in the valve body, one fixed bushing 44 nearest the tracer stylus, 49, and one movable bushing 45 remote from the stylus, the latter being adjustably coupled by a connection 46 to the auxiliary slide 29. Movement. of the tracer under control of the pattern 51 increases the pressure on one or other side of both pistons but the small auxiliary piston responds first and moves the auxiliary slide quickly by the amount of the tracer deflection. The connection 46 causes a compensating shift of the bushing 45 so that it returns to a neutral position with respect to the spool 80 and as the piston 37 is then hydraulically locked the auxiliary slide moves as one with the main stide 27 and valve body as they are given the copying movement by the main piston 33. When the main piston movement is sufficient to restore the tracer-valve spool 65 to the neutral position with respect to the fixed bushing 44, the position of the spool 80 with respect to the. movable bushing 4$is such as to reverse the initial direction of flow to the piston 37 and so.: restore. the piston and, through the connection 46, the movable bushing to their neutral positions. The saddle 13-. is -fed. longitudinally by a rack and pinion 25, 24 worm drive 22, 20 and a splined feed.shaft 19. The machine is stated to be particularly applicable to copying cams from a rotating pattern, where. sharp reversals of curve are involved.
