Patent GB-845873-A (GB)
Title: Improvements in and relating to the manufacture of metal chromates
IPC: C01G37/14
Filed: 1956-07-05
Abstract: A mixed chromate pigment of lead and zinc is prepared by heating a mixed lead-zinc ore, for example anglesite-cerussite-calamine ore, with an aqueous alkaline solution until at least a part of the crystalline carbonates, sulphates and silicates present have been converted to the corresponding amorphous basic form, and the resultant insoluble material is heated with chromic acid or a compound thereof, such as sodium chromate or potassium dichromate. The aqueous alkaline solution treatment is preferably carried out under pressure at above the normal boiling point of the solution, for example in an autoclave.  The alkaline solution has a pH of 7.6 or more, preferably 10-14, and may be a solution of sodium hydroxide or carbonate, or preferably the alkaline brines or tailings from bichromate manufacture, which consist essentially of sodium and calcium chromate, together with excess alkali in the form of hydroxide, carbonate, aluminate and silicate.  These tailings may also be employed as the source of chromic acid, after acidification; other waste liquors, such as those from chromium plating, may be similarly employed.  The reaction with the aqueous solution of chromic acid is preferably carried out in open vessels at 80-100 DEG C.  The brilliance of the pigment is increased by the presence of small amounts of lead and zinc borates, which may be formed in situ by adding boronatrocalcite to the raw material. Impurities present in the starting materials are only detrimental to the brilliance, and not to the anti-corrosive properties of the pigments.  The presence of iron, calcium, strontium and barium chromates in the pigment renders the pigment especially suitable for the protection of light metals, such as aluminium.  A green pigment may be obtained by adding ferrocyanide blue, which may be prepared in situ from iron present in the ore.

Title: Improvements in or relating to fishing tools for use in well drilling operations
IPC: E21B31/18
Filed: 1929-07-08
Abstract: 340,292. Borehole apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Doheny-Stone Drill Co. ; Torrance, California, U.S.A.) July 8, 1929, No. 20909. [Class 85.] A tool for recovering lost drills, casing &c. from wells comprises a barrel adapted to fit over the drill &c. and provided with wedge slips individually movable longitudinally and radially to grip the drill &c., an annular follower of rigid material acting directly on the upper ends of the slips to move them into corresponding positions. The barrel 11 has a spiral lower end, of which the vertical edge 23 may be pressed outwardly to facilitate centring the drill &c. Wedge slips 38 are mounted in inclined ways 37 and have a tongue and groove connection 42 therewith. The slips preferably have thread-like serrations on their gripping faces, whereby, if the drill &c. is immovable, the tool may be released therefrom by rotation. Above the slips is a loose tubular member 46 from which fingers 48 depend one into each way 37, the member 46 containing a rubber &c. ring 52 adapted to be adjusted to the desired diameter by a threaded ring 57a ; in a modification, the rubber &c. ring is arranged in an outer ring separate from, and resting on, the member 46. The ring 52 has a bevelled lower end resting on a corresponding seat and has an annular upper extension 55 engaging a recess in the ring 57a. In use, the tool is lowered over the work, fingers 48 tending to keep the slips level ; the slips are then engaged with the work by an upward pull. As the ring 52 closes the space between the work and the barrel, the pressure of the flushing fluid may then be used to act on the ring 52 as a piston to cause the slips to take a tighter grip. The ring 52 may be omitted, the bore of the member 46 then engaging the work.

Abstract: 1375066 Explosively-actuated fastener-driving tools HILTI AG 8 May 1972 [7 July 1971] 21308/71 Heading B4C A device for use in securing hot-top tiles to a pair of opposed walls of a chill mould, comprises a support carrying a pair of explosivepowered fastener-driving tools arranged with their drive-in axes substantially co-axial, and with their drive-in directions opposed and extending away from each other. The support also carries a pair of holders, each being adapted to hold a respective tile in front of a respective one of the tools. As illustrated, the support comprises two arms 2, 3 pivoted at 5, and brackets 9, 10 pivotally mounted on shafts 8, 7. Three naildriving tools 16, 17 are carried by each bracket and each holder comprises an arm 12, 13 integral with the respective bracket and two spring- biased arms 18, 19 pivotally mounted on the shafts.

Further extension of the ram causes the barrels 16a, 17a of the tools to be forced into their respective housings so as to condition the tools for firing, which firing is effected from a remote location. Relative pivoting of the arms 2, 3 may alternatively be effected by an electric motor or an electromagnet. The device may be provided, in addition, with an arrangement of tools and holders similar to that described above for securing tiles to the other pair of opposed walls of the chill mould.
