Title: Improvements in or relating to apparatus for use in Dewatering Sludge
Inventor: COACKLEY PETER
IPC: C02F11/15
Filed: 1965-10-08
Abstract: 1,170,413. Electro-osmotically dewatering sludges or slurries. MOTHERWELL BRIDGE & ENG. CO. Ltd. Dec.1, 1966 [Oct. 8, 1965], No.42742/65. Heading C7B. Sludge is dewatered electro-osmotically in apparatus comprising a hollow elongated anode device, e.g. tubular casing 12, having inlet 13 and outlet 18; an elongated cathode device, e.g. rotary tube 15, within the anode device and presenting therewith opposed longitudinally extending faces defining an elongated e.g. annular passage; blading 16, e.g. rotary helical, in the passage for conveying sludge therethrough from inlet to outlet; and ducting extending from one of the passage-defining faces, e.g. consisting of the bore and perforations in the wall of tube 15, for flow of water. Preferably the helical blading is insulated from the tube and casing by being of epoxy or polyester resin or painted with polyurethane paint. The blading may rotate relative to the tube to maintain the perforations clear of sludge, or may be carried by the tube which rotates in the casing. As shown, the casing and blading may taper towards the outlet. A cylindrical screening sleeve (24, Fig.5) may surround the perforated tube 15 to assist filtration. Apertures (23, Fig.4) for water drainage may be formed in the helical blading. The casing 12 may be disposed upright with an annular receptacle 19 surrounding the outlet 18 and housing a rotary scraper 20 driven with the tube 15. The cathode device may include an endless-belt conveyer (51, Fig.7) defining with the casing a U-passage for the sludge, the blading consisting of outwardly projecting blades (56) on the perforated belt. A vacuum may be applied to the ducting and the casing may be constructed of sections insulated from one another so that a potential gradient may be applied from end to end. The apparatus may also be used to dewater slurries, such as in draining silts, boulder clay suspensions and peat.

Abstract: 911,746. Blasting. MARSTON EXCELSIOR Ltd. Jan. 4, 1961 [Dec. 18, 1959], No. 43046/59. Class 38 (4). An electrically fired detonator, not shown, connected to terminals 7, 8 of a portable shot exploder is fired when a condenser 4 charged from the high-voltage output of a D.C. converter 2 is discharged through it. The D.C. converter 2 derives its low voltage impact from a small number of 1¢-volt cells 1 and charges the condenser 4 through switch member 5 when it is connected to the terminal 3. The detonator is fired; when the condenser is subsequently discharged through it, by moving switch member 5 so as to abut terminal 6. The D.C. converter may preferably consist of a pair of transistors used as an oscillating switch, followed by a voltage step-up transformer and a bridge rectifier. The voltage output of the converter may be adjusted to suit varying detonator circuit conditions and the oscillation of the switch maintained by a regenerative winding on the step-up transformer or by a separate transistor oscillator.

Abstract: 1,012,158. Reservoir pens. F. A. ECKERLE. Nov. 22, 1962 [Nov. 22, 1961], No. 44261/62. Heading B6P. [Also in Division F1] The liquid of a dispensing cartridge, e.g. the ink column of a ball-pen, is subjected at its inner end to the pressure of a gas which is generated in proportion to the rate at which the liquid is used so as to maintain a constant pressure. In one form, Fig. 1, the barrel 12, which has a larger than capillary size diameter, is made of one metal, e.g. brass, and has a strip or strips 24 thereon of another metal, e.g. zinc, the two metals having different positions in the electromotive series. The usual grease plug 20 floats on the ink surface and between it and a rubber cap 16 closing the barrel is an electrolyte 22. One of the metal surfaces 12, 16 or both is or are coated with an insulating layer 26 which is dissolved away by the plug 20 as it follows the ink so as to expose the two metals and cause the generation of gas as the ink is used, the pressure above the ink column thus being maintained. The electrolyte may be in paste form so that it moves with the follower 20. Alternatively the material of the follower may be such that it acts as an electrolyte as well as a solvent. Moreover, the electrolyte may be constituted to act also as the solvent. If, however, the ink is such that it is incapable of acting as an electrolyte, no protective coating on the metals is necessary. The barrel may be of non-metallic material and a composite strip of the two metals may be supported from the cap, and may comprise two wires twisted together. In another form, the gas may be produced by chemical action. A rod coated with sodium carbide or sodium peroxide is supported axially in the barrel, and a quantity of water or aqueous paste is placed above the follower 20. As parts of the rod are exposed by movement of the follower, the coating thereon coacts with the water to produce the gas.

Abstract: Beta-hydroxyacid polyesters are made by reacting a ketene with a ketone or aldehyde of formula <FORM:0931144/IV(a)/1> where R is a hydrocarbon radical or a substituted hydrocarbon radical and X is hydrogen, a hydrocarbon radical or a substituted hydrocarbon radical. According to the invention, reaction is effected in the presence of a catalyst which is (i) a compound of formula M1OR1 where M1 is a Group Ia metal and R1 is a monovalent hydrocarbon or substituted hydrocarbon radical; (ii) an organic compound of beryllium, magnesium, tin, lead, a Group IIb metal or a Group IIIb metal, in which one of the valencies of the metal is satisfied by a hydrocarbon, substituted hydrocarbon, oxyhydrocarbon or substituted oxyhydrocarbon radical and in which the remaining valencies are satisfied by hydrogen atoms, halogen atoms or further hydrocarbon, substituted hydrocarbon, oxyhydrocarbon or substituted oxyhydrocarbon radicals; (iii) a hydride of a Group Ia metal; or (iv) a complex aluminium hydride of formula M1AlHxY4-x where M1 is a Group Ia metal, Y is a hydrocarbon or oxyhydrocarbon radical and x is 1-4.  Reaction is preferably effected at -20 DEG  to -100 DEG C., possibly in the presence of an organic liquid (e.g. dimethyl ether, diethyl ether, higher ethers, toluene or dimethyl formamide).  Specified reactants are:- ketenes-ketene itself, dimethyl ketene, methyl ethyl ketene, diethyl ketene and dibenzyl ketene; ketones-acetone, methyl ethyl ketone, hexanone-2, hexanone-3, pinacolone and benzophenone; aldehydes-acetaldehyde, propionaldehyde, n-or iso-butyraldehyde, n- or iso-valeraldehyde, benzaldehyde, heptaldehyde, 2-ethylhexaldehyde, 3:5:5-trimethylhexaldehyde and furfurol.  Many of the polyesters are soluble in benzene, o-chlorophenol, chloroform and dimethyl formamide and are useful in the manufacture of fibres, films or moulded articles.
