Patent GB-777041-A (GB)
Title: Improvements in coagulation and sludge conditioning
Inventor: HARWOOD JOHN HOLLEY
IPC: C02F1/52
Filed: 1953-09-12
Abstract: A modification of the process of the parent Specification comprises mixing with a sewage medium a solution of a basic chloride of aluminium, iron or chromium, the ratio of the number of chloride ions in this solution to the total number of chloride ions which would be present in an equal volume of an equimolar solution of the normal chloride salt alone lying in the range 17 to 40 per cent.  The minimum quantity of basic aluminium chloride solution necessary to produce coagulation, and calculated as Al2O3, amounts to approximately 0,6 per cent of the dry solids content where the sewage medium is a sludge.  The basic chloride solution may contain approximately 15 per cent by weight of the basic chloride calculated as R2O3, but the amount is not critical.  Chlorides having a "chloride-ion ratio" (as above defined) of 25 per cent are particularly suitable, and solutions of chlorides corresponding to formulae ranging from R2Cl2(OH)4 to R2Cl(OH)5 (the aforementioned ratio ranging from 34 to 17 per cent) may be economically prepared. Aluminium chlorohydrate having a ratio lying in the above range is preferred.  Examples are given of the application of the process to raw primary sludge, cold digested primary sludge, mesophilic digested primary sludge, elutriated digested primary sludge, activated sludge, humus sludge and mixtures.  It may be applied to thermophilic digested primary sludge.  The age of the sludge or mixture varied from nil to seven days.  An improvement in filtration rate was observed in all cases.  Specification 516,706 is referred to.

Title: Improvements in or relating to closure devices for bottles, jars or the like
IPC: B21D51/48
Filed: 1926-08-16
Abstract: 280.839. British Sure Seal Co., Ltd., and Stephens, W. A. Aug. 16,1926. Hollow - ware. - A method of feeding cap blanks to a rotary holder on which the blank is to be worked consists in bringing the blanks to a position of rest opposite the holder and tilted from the vertical, moving the tilted blank up to the holder, then setting the blank parallel to the holder and finally pushing it into engagement therewith. Apparatus for carrying out the method is described in connection with the machine for assembling a retaining band around a cap described in Specification 280,623 according to which metal strips S fed successively along a platform 16, Figs. 1 and 3, have their tongues bent outwards through an angle of 90‹ or more by a plunger 19 and are engaged by a rotatory holder H which curls them and links the tongue and slot, a presser 47 finally bending back the tongue to secure the connection. The holder is driven intermittently, one revolution at a time, by a pinion 54 which meshes with a pinion 53 on the shaft of the holder and is driven by a pawl 56 on a diametral arm 55 oscillated by a crank disc 58 on a shaft 4 driven from and at the same speed as a main shaft 3. During a period of rest of the holder H, a strip is fed to it ready for curling and a cap is supplied by a reciprocating carrier C, Fig. 5, which consists of a U-shaped member C inclined to the vertical. Caps are fed to it one at a time down an inclined shoot 64, a projection 78 on a pivoted arm 76, controlled by a cam 10 on the main shaft 3, checking the movement of all but, the first cap. The cap thus held back is prevented from contacting with the cap in the member C by a slide 70 secured thereto. The member C is supported by a sleeve 65 which is mounted on the machine base and through which passes an inner tube 66 adapted to receive a slidable rod 67 having secured to its end a boss 89 between which and the tube 66 a spring 68 is disposed. As the strip is fed to the holder H, a cam 11 on the main shaft 3 actuates a lever 11<a> the outer end of which is connected to the boss 69, the tube 66 being thereby displaced and moving the member C until the lower part of the cap contacts with the holder H, a spring-pressed pivoted guard plate 71 being pushed out of the way of the member C by a projection 73 on it. When further movement of the member C is arrested, the continued movement of the lever 11<a> compresses the spring 68 and causes the rod 67 to push the cap on to the holder H. The strip is then secured around the cap and the cap and strip are removed from the holder by an ejector rod disposed in the holder. The cap and strip fall from the holder and are guided into a delivery shoot 75 by wings 74 on the guard plate 71. Specification 170,405, [Class 125 (ii), Bottles &c.. Filling &c.], also is referred to.

Filed: 1923-10-17
Abstract: 206,822. Soc. l'Oxhydrique Franþaise. Nov. 7, 1922, [Convention date]. Hydrogen.-In the manufacture of hydrogen by the iron-steam process the reducing gas required for regenerating the metal is heated by the waste of blast furnaces, gas works, coke ovens, metallurgical plant and like installations from which the reducing gas itself may be obtained, the hot excess reducing gases being utilized in the burners of the installation or returned to the gas main. In an example coke oven gases required for the reduction are heated by passing them through brick heat recuperators in which the reducing apparatus is situated. Burnt gases after heating the ovens pass through the iron oxide and finally give up their heat to the usual brick piles of the recuperators. The coke oven gas preheated in the recuperators passes on to the reducing apparatus containing the hot iron oxide, the issuing gas containing the excess reducing gases being employed in any part of the plant. In a second example coal gas to be used for the reduction after the recovery of bye-products and de-sulphurization, is preheated in the dampers in which the drawn coke is extinguished. In a third example the reducing gas is produced independently of the cokeovens, gas works, metallurgical plant &c., but is heated by the waste heat of the latter.
