Filed: 1968-08-01
Abstract: 1,185,599. Vehicle bodies. H. D. HEWITT. 1 Aug., 1968 [8 Nov., 1967], No. 36703/68. Heading B7B.

Title: Improvements in or relating to electrical safety systems
IPC: F23N5/08
Filed: 1965-08-27
Abstract: 1,109,456. Photo-electric burner control. ELECTRONICS CORPORATION OF AMERICA. Aug. 27, 1965 [Sept. 4, 1964], No. 36892/65. Heading G1A. [Also in Division F4] A burner control system is made to fail safe by periodically chopping the radiation from the flame falling on a detector 20. Thus when a flame is detected relay 24 is repeatedly energized and de-energized; in one state capacitor 44 is charged from a power source 40 and capacitor 46 is discharged through a relay 32, and in the other state capacitor 46 is charged and 44 discharged through the relay. Relay 32 is maintained energized by the repeated discharges to keep contacts 34 closed and the burner fuel valve 16 open. If the flame fails relay 24 remains de-energized and when 44 has discharged relay 32 drops out to close valve 16. If a fault develops whereby a flame signal is generated even when the cell 20 is unilluminated relay 24 remains energized and again valve 16 is closed. In a modification relay 32 is replaced by a double winding relay with the junction between the windings connected to the point 52, Fig. 2 (not shown). This permits the insertion of a resistance to make the discharge time of the capacitors 44 and 46 different. The relay 24 may be replaced by a switching transistor, Fig. 3 (not shown), or alternately illuminated photo-resistors.

Title: Improvements in conveyor elevators

Filed: 1965-08-31
Abstract: 1,095,081. Endless conveyers. CROP HANDLERS Ltd. Nov. 28, 1966 [Aug. 31, 1965], No. 37248/65. Heading B8A. An endless belt or chain elevator is in the form of a boom 16 pivotally supported by an upright 13 so that it can partake of a see-saw movement the limits of which are restricted by means of chains 21, 22. In use, a bale or bag (not shown) is placed manually on the lower end of the elevator and when it passes the point at which the latter is pivotally connected to the post 13, the boom tilts to lower the discharge end so that the drop of the bale or bag on to a trailer 30 to be loaded, is reduced. The height of the post 13 may be varied by the action of a winch 29 acting through a lever 25 and chain 27. The bale or bag is discharged on to a platform 37 which is thereby tilted into a discharge position against the action of a spring 41. This action is arranged to stop the drive motor 18 of the elevator. The elevator can rotate about the post 13 and is limited by the provision of chains (23a), (24a) (Fig. 2, not shown). The effective length of the chain 21 may be varied by pulling it through a sleeve 33 which is formed with a chain securing notch (34) (Fig. 4, not shown).

Title: Method of recovering metals
Inventor: DAUGHERTY CHARLES CLIFTON
IPC: C22B7/00
Filed: 1965-09-01
Abstract: Cobalt and/or nickel are recovered from a normally acid-resistant alloy by treating said alloy with an aqueous hydrochloric acid/chloride nitrate solution in which the hydrogen chloride concentration is less than 20.2% by weight.  The nitrate may be any water-soluble inorganic nitrate e.g. of an alkali metal and I to 1.5 parts by weight to 3 parts of hydro-chloric acid may be used.  The solution may be treated with air and calcium carbonate to precipitate hydrated chromium and iron oxides which are removed by filatration, followed by treatment with chlorine and calcium carbonate to precipitate cobalt as hydrated cobaltic oxide at pH 3.  Filtration followed by addition of hydrated lime precipitates the nickel as hydrated oxide.

Title: Production of dispersions
IPC: C09K23/00
Filed: 1946-12-20
Abstract: Dispersions, obtained by the process of Specification 515,582, with the use of the preferred dispersing agents and in the presence of a water-soluble protein, are concentrated by acidifying the dilute dispersion to a pH below the isoelectric point of the protein, mechanically removing the water from the so-flocculated dispersion and reconstituting the dispersion by raising the pH above the isoelectric point.  In an example, a dilute polythene dispersion is flocculated by the addition of glacial acetic acid and water is removed by filtration.  The resulting paste has ammonia added with stirring, thus giving a concentrated dispersion.  As an additional dispersing agent the condensation product of a fatty alcohol, e.g. cetyl alcohol, with ethylene oxide, may be used.  Mechanical means for removing water from the flocculated dispersion also include centrifuging or skimming.ALSO:A dilute polythene dispersion, prepared by the process of Specification 515,582 with the use of the preferred dispersing agents and in the presence of a water-soluble protein, is concentrated by acidifying to a pH below the iso-electric point of the protein, mechanically removing the water from the so-flocculated dispersion and reconstituting the dispersion by raising the pH above the protein iso-electric point.

A mechanism for operating an isolator or switch by turning a tube or the like 15 comprises an arm 16 rigidly clamped to the tube and having an operating handle 18 pivoted thereto at 19. In its inoperative position the handle 18 seats in one of three recesses 22 . . . 24 in a plate 21 which is adjustably bolted to the frame 12. The recesses 23, 24 act as end stops for the operating handle 18 and by adjusting the plate 21 the angle through which the handle 18 can turn the tube 15 can be altered, in order to allow for different lost-motion with different lengths of tubing 15. In order to move the isolator a " figure lock " is first turned to remove an obstruction and allow the handle 18 to be raised to the horizontal position. The arm 16 and tube 15 can then be turned in a direction determined by a manually adjustable member comprising a spindle 31 on which two abutments 34, 35 are mounted at right-angles to each other, the arm 16 being prevented from movement in one direction by the vertical one of the abutments 34, 35. The handle 18 then drops to the vertical position shown and is located in the corresponding recess 23 or 24. The key of the " figure lock " is then turned to lock the handle in that position and to allow the key to be withdrawn. The handle 18 can be locked in each recess by passing a padlock through apertures 20.

Title: A method for the production and control of translatory motion in processes for the manufacture of shaped semiconductors
IPC: C30B13/30
Filed: 1964-09-25
Abstract: In the progressive crystallization, crystal-pulling or zone-melting of a volatile semi-conductor material entirely within a pressure vessel, the required relative movement is transmitted from the upper surface of a liquid contained within the vessel and in communication with the outside of the vessel through a valved conduit, the level of which surface is raised or lowered by introducing further liquid under pressure or by running off liquid from the vessel respectively. A relative rotary movement may be effected by means of a magnetic coupling.  The semi-conductor material may be selenium, tellurium, cadmium sulphide, or gallium arsenide.  In one embodiment (Fig. 1), a water-cooled autoclave (1) supplied with inert gas at a pressure of up to 150 atmos contains a crucible (6) which is surrounded by a heating element (8) and is attached to a cylindrical float (4) on oil (3) in the bottom of the autoclave.  A molten body contained in the crucible is progressively crystallized by opening an oil outlet valve (15), thus lowering the level of oil in the autoclave and downwardly withdrawing the crucible from the heating element.  In another embodiment (Fig. 2), the autoclave contains a crucible (33) and pulling rod (29) which is attached to an annular float chamber (27) containing oil (26) and having an inlet valve (37) for oil under pressure.  A crystal is pulled from melt in the crucible (33) by opening the valve, thus increasing the level of oil in the chamber and raising the rod.
