Title: Improved process for treating sewage sludge
IPC: C02F11/12
Filed: 1934-07-23
Abstract: A solution of formaldehyde is obtained from the gases given off from sewage sludge undergoing digestion and which contain methane and some carbon dioxide by partially burning the methane or by passing the gases into ozonized air, and then passing the gases through water.ALSO:The de-watering of sewage sludge by filtration, for use as fertilizer or prior to incineration, is promoted by previously elutriating the sludge with water, separating the sludge from the water by settlement or otherwise and treating the separated sludge with a coagulant, such as chlorinated copperas, ferric chloride, ferric sulphate or aluminium salts.  A portion of the sludge only may be elutriated and this portion mixed with sludge that has not been elutriated, the mixture being then treated with coagulant. Sludge from raw sewage, digested sludge or activated sludge or mixtures of these different kinds of sludge may be treated in the way described. The sludge may be treated either before or during elutriation with de-ammonifying agents such as chlorine, hypochlorites, nitrous oxide or formaldehyde.  In elutriating, the sludge and water may be agitated by means of air under pressure. Countercurrent elutriation using two or more decanting vessels may be performed.  When ferric salt is used as coagulant, the water filtered from the sludge may be chlorinated and used for elutriating further sludge.  A solution of formaldehyde for treating the sludge may be obtained from the gases, given off from sludge which is undergoing digestion and which contain methane and some carbon dioxide, by incompletely burning the methane or by passing the gases into ozonized air, and then passing the gases so treated through water.

Abstract: 1323032 Rock bolting C I WILLIAMS 19 April 1971 [18 Feb 1970 3 Aug 1970] 21503/71 Heading F2H A rock bolt adapted to be held in a mass of grout placed in a hole in a ground formation, has a threaded end adapted for engagement with a nut 17 and is surrounded by the grout initially in the liquid condition thereof, the peripheral surface of the bolt 12 being formed to define a transverse indentation having a maximum slope with respect to the axis of the bolt, at least on the side of the indentation most remote from the threaded end, of less than fifteen degrees and preferrably about ten degrees. The bolt may be coated to prevent its adhesion to the grout. Helical indentations, Fig. 3 (not shown) may be made by a process similar to thread rolling or a series of annular indentations, Fig. 4 (not shown) by a sequence of rolling operations accompanied by repeated indexing of the rod through the rolling machine. In each case a degree of cold work to the material adjacent the indentations will compensate for the reduction of cross-sectional area. Rolls, Fig. 5 (not shown) for forming a helical pattern may be sufficiently spaced to allow axial ribs to be squeezed out. Another configuration has a wave-like pattern mainly in one axial plane, Figs. 6, 7, 8 (not shown). Preferred relationships between rod diameter, pitch and depth of undulations are indicated. A coating of lubricant on the rod assists its wedging reaction with the hole whilst preventing adhesion to the grout.

Patent GB-638926-A (GB)
Title: Improvements relating to the production of magnesium oxychloride cementitious compositions
IPC: C04B28/32
Filed: 1947-08-08
Abstract: The tendency towards excessive shrinkage after setting of a magnesium oxychloride cement produced from a mixture including magnesium oxide in a form which normally imparts such tendency to the cement, is reduced by mixing the magnesium oxide with magnesium chloride and water in the presence of a water-soluble salt of a phosphoric acid having a lower proportion of combined molecules of water than orthophosphoric acid, examples of suitable salts being sodium triphosphate, sodium tetraphosphate, sodium pyrophosphate and acid pyrophosphate, sodium metaphosphate and polymetaphosphate, and Na14P8O27.  The invention applies particularly to cement produced from magnesium oxide derived from seawater, and the phosphate is preferably mixed with the magnesium oxide before mixing with the magnesium chloride.  The cement composition may also contain sand, limestone, asbestos and ferric oxide.  The Specification as open to inspection under Sect. 91 refers also to the use of these phosphates to inhibit hydration of magnesium oxide in other fields than oxychloride cements, such as inhibiting the thickening of a magnesium oxide slurry.  This subject-matter does not appear in the Specification as accepted.

Abstract: 479,073. Locks; turnstiles; voting- apparatus; check-freed apparatus. WOLLASTON, H. J. BUCHANAM-. Aug. 8, 1936, No. 21867. Addition to 447,913. [Class 44] [Also in Groups XVIII and XIX] The lock described in the parent Specification is modified so that the tinlocking key or ticket is retained, another key of the correct pattern being required for a second unlocking. The bolt 2, Fig. 1, slides in frame 1 and carries the actuator 3, guide rods 4A, 4B, tumblers 5A, 5B and keyslit 6. The operating handle first depresses the actuator 3, then moves it laterally, and finally releases it. Electrical operation may be provided and the key may form part of the operating circuit. When the lock is horizontal, the frame 1 closes the rear of the key-slit in the locked position, but leaves the slit open when unlocked so that the key falls through into a suitable receptacle. When the lock is vertical, a wire spring is used to force the key out of its slit. To remove incorrect keys, Fig. 5, a metal leaf 4F actuated by knob 5E slides through the bottom 2D of the case into the key-slit 1C. In a modified lock, Fig. 9, with a key-slit 1D and four pairs of tumblers 6A, 6B, carried by the bolt 2E and engaged by the actuator 3C, the tumblers pass through a plate 5H fixed to the casing and slotted as shown in Fig. 10. The key has for each pair of tumblers a small hole for the rod of 6A and a large hole for the body of 6B. The tumblers may be rotatable and may have irregular shaped ends, as described in the parent Specification. The lock may be adapted for use in a coinfreed machine, Fig. 11. The sliding tray 1 has a pocket 12 and knob 14, and carries a rack 15 engaged by a pinion 16 fitted to the handle of the actuator. The key-slit 17 has a clearing device worked by knob 18. The action is such that the unlocking is completed and the key or ticket dropped before the tray is far enough out for a packet to be extracted or dropped, the tray being returned by springs or weights. The lock may be adapted for use with turnstiles, a toothed ring on the turnstile engaging a tapered pawl or tongue on the frame, the pawl engaging the actuator and withdrawing the bolt when a correct key is used. The lock may also be adapted for voting- machines, the key or ticket being punched by an issuing machine and the bolt actuating a counting mechanism and alarm indicator. The tickets may be bilaterally symmetrical about one or both axes to allow them to be used either way round or either face to the front.
