Abstract: 1,256,275. Comminuting ores. P. G. KIHLSTEDT. 24 March, 1969 [25 March, 1968; 11 April, 1968], No. 15398/69. Heading B2A. [Also in division Cl] Cold-bound pellets or other agglomerates of a metalliferous ore, e.g. iron ore concentrates, are produced by forming a particulate mixture of the ore moistened with water, the mixture comprising predominantly a coarse component and the remainder a fine component, the fine component being one in which at least 80% by weight has a particle size of less than 0.08 mm. and the coarse component having a particle size distribution lying on a particle size level substantially five times as high as that of the fine component; adding to the particulate mixture at least one finely ground material selected from slaked slag, slaked lime and Portland cement, as binder, grinding the mixture until it is substantially homogeneous, forming the homogenised mixture in pellets or other agglomerates, adding water if necessary; adjusting the water content of the agglomerates so that they contain not more than 5% by weight of water; and finally steam treating the pellets at 160-230C. at up to 70 atmospheres for up to 24 hours. The moist mixture is advantageously ground in a rod mill with the binder to produce a homogeneous mixture and is preferably ground to a degree corresponding to a gross energy supply to the grinder of 1-10 kilowatt hours/ton of mixture. This mixture is pelletised by rolling immediately after grinding. Slaked steel furnace slag is particularly suitable as the binder, and is finely ground and slaked before formation of the mixture into pellets. More than one binder may be used in the mixture, e.g. a mixture of ore and binder containing 2-20% slaked slag and up to 10% by weight each of slaked lime and Portland cement are suitable for use in the process. The ore is preferably ground to give a coarse fraction or a fine fraction having different particle size distributions, but the fractions may have continuous particle size distributions, the coarse component having a K80 value of 0.4 mm. and the fine component having a K80 value of 0.08 mm.

Title: Improvements in or relating to manures
IPC: C05F17/00
Filed: 1933-05-30
Abstract: 404,203. Manures. HORTEN, A., 94, Schweinfurthstrasse, Dahlem, Berlin. May 30, 1933, No. 15559. [Class 111.] Liquid manure is produced by pulverizing fresh dung or plant waste in a mill A, adding liquid if necessary, and pumping the mixture into a receptacle E where it is brought into a state of rotting by means of air forced in under pressure, preferably at a pressure of 2-3 atmospheres ; the mixture is then passed into a second receptacle H where it is impregnated with carbon dioxide and ammonia contained in the air transmitted from the first receptacle and produced therein by the rotting. The mixture flowing to the rotting receptacle E is guided through a heat exchanger D where it is heated to about 40‹ C. by means of the rotted mixture flowing to the second receptacle H and which is itself cooled from 80-60‹ C., the temperature to which the mixture in the rotting chamber is heated by the rotting process, to 20-30‹ C. The carbon dioxide and ammonia produced by the rotting in the receptacle E are not absorbed by the liquid therein owing to the elevated temperature but collect at the top of the receptacle E and pass together with the rotted mixture to the receptacle H where they are. absorbed in the cooled liquid. The receptacle H may be open at the top or formed with an opening in the lid which may be closed by a valve V ; the valve is normally open to allow the air to escape but it may be closed to generate a pressure to assist in driving the final product out of the outlet 0. The receptacle E, the temperature exchanger D and the fluid conduits may be heat insulated and additional cooling means may be inserted between the exchanger D and the receptacle H or upon the latter. The air may be forced into the receptacle E at the lowest part so that any matter settling is continuously whirled upwards and the air may be distributed therein by devices such as perforated tubes, plates &c. ; the receptacle E may contain perpendicular baffles. The mixture before entering the receptacle E may be mixed with chalk for neutralizing purposes, or with crude phosphates which are rendered assimilable during the rotting process.

Title: Improvements in or relating to electronic digital computing devices
Inventor: WILLIAMS FREDERIC CALLAND
IPC: G06F9/30
Filed: 1949-06-14
Abstract: 734,071. Digital electric calculating-apparatus; electric digital-data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 5, 1950 [June 14, 1949; June 22, 1949], Nos. 15848/49 and 16585/49. Divided out of 731,341. Class 106 (1). An electronic digital computer comprises a first or main storage device and a second or instruction storage device, at least one of which requires repeated regeneration of its contents, any necessary regeneration of one storage device being effected during reading into or out of the other storage device and vice versa. The time required for an operation cycle of the computer is thus reduced. The computers described are modifications of the machine described in Specification 731,341 employing C.R.T. stores as described in Specifications 645,691, 657,591 and 705,474. In the form shown in Fig. 9, the control instruction only is stored in the control unit CIS on a single line of the C.R.T. 25, and selects the present instruction from a separate instruction store IS through staticisor ISTR. The latter instruction is passed directly to the main staticisor MSTR comprising portions L and T for selecting an address (line and tube) in the main store MS, and a functionselecting portion F. The scan and action beats of MS are interleaved with those of IS whereby a normal operation cycle or bar comprises only two beats instead of four, the next control instruction being formed and sent to ISTR while the previous present instruction is being obeyed. The unit PPU is thus arranged normally to emit a prepulse every two beats, but is inhibited during multiplication (function digits 101) which may be performed as described in Specification 712,172, and during the performance of a Test instruction (digits 011). In the alternative two-beat computer shown in Fig. 10, the control unit CLS is similar to that described in Specification 731,341, and the store IS comprises a single C.R.T. only whose screen has a 32-line storage capacity. A special instruction s, I (function digits f o ) set up on the P.I. line of CLS, opens and closes gates and sets a trigger circuit SITR so as to cause a block of instruction words stored in addresses s, s+1 ... s+31 of the main store MS to be transferred to lines l, l+1 ... l - 1 of IS during successive scan beats of the latter (action beats of MS); " 1 " is repeatedly added to the P.I. line of CLS through gate 65, and the number l, entered on the C.I. line through unit LNU and gate 62, is repeatedly compared in unit 64 with the current line number plus " 1 " obtained through unit LNU and adder 63. Thus during the scanning of the last line l - 1, the ,unit 64 detects agreement and sends a resetting pulse to circuit SITR. The first of the new instructions to be obeyed (line l) may then be passed through gate IGA and set up on the main staticisor MSTR. Specifications 682,156, 692,853, 693,424, 705,477, [Group XI. (c)], and 705,479 also are referred to.
