Title: Method of treating ore fines and product thereof
IPC: C22B1/14
Filed: 1956-11-09
Abstract: A process for preparing a product for use in iron refining comprises continuously reducing iron oxide fines to remove 70-94% of the oxygen and agglomerating the product without reoxidation. Iron oxide, e.g. iron ore, of a size 3/8 inch or finer may be partially reduced in a fluidized bed by hydrogen, carbon monoxide or a mixture thereof, to FeO with traces of higher oxides and iron and the produced oxide further reduced in a second fluidized bed until the oxygen has been reduced to 5-15% on a gangue-free basis.  The waste gas from the second fluidized bed may be used for the first partial reduction. The product of the second process, i.e. iron and FeO, may be briquetted and used in place of scrap in iron refining processes.

Title: Improvements in or relating to hard metal carbide products and their manufacture
IPC: C22C29/00
Filed: 1954-12-02
Abstract: Hard metal carbide bodies are produced by re-crystallizing a mixture of hard metal carbides consisting predominantly of titanium carbide by heating, comminuting the re-crystallized carbides and intimately mixing with nickel powder and with one or more other powdered binder metals, heating the mixture, the proportion of binder metals to carbides and the temperature being sufficient to melt the binder metals and form a binder-carbide eutectic, comminuting the mixture and pressing and sintering to form the body.  The hard metal carbide is preferably predominately titanium carbide and may also contain niobium carbide, tantalum carbide, iron carbide, and tungsten carbide and the binder metal is preferably nickel with or without chromium, cobalt, manganese and ferrotitanium.  In one example, a ball-milled mixture of titanium carbide and tantalum-columbium carbide was passed at a rate of 1/2 inch per minute through a furnace at 2600 DEG C. and the re-crystallized carbide, were crushed to -100 mesh.  A powdered binder mixture of 50 per cent chromium, 50 per cent nickel was then prepared and sintered at 1050 DEG C. and the binder was mixed with the carbide in the proportion of 85 per cent carbide, 15 per cent binder.  The binder-carbide mixture was pre-sintered at 1250 DEG  to 1200 DEG C., granulated and passed at 1/2 inch per minute through a homogenizing furnace at 1900 DEG C. to form the binder-carbine eutectic.  The mass was then cooled, crushed and ball-milled to 5 micron size and the bodies formed by pressing and sintering.  In another example, a powdered binder mixture of 35 per cent manganese, 42.5 per cent chromium and 22.5 per cent nickel was sintered at 950 DEG C. and mixed, with the carbide in the proportion of 70 per cent carbide, 30 per cent binder.  The mixture was pre-sintered at 1050 to 1150 DEG C. and homogenized at 1,750 DEG C.  In a further example, a powdered binder mixture of 37.5 per cent chromium, 37.5 per cent nickel and 25 per cent ferrotitanium was sintered at 100 DEG C. and mixed with the carbides in proportion of 70 per cent carbide, 30 per cent binder. The mixture was pre-sintered at 1150 to 1200 DEG C. and homogenized at 1750 DEG C.  The Provisional Specification includes the use of a single carbide and a single binder metal, whilst in Example 1 the mixed carbides contain 3-4 per cent iron carbide and homogenization takes place at 1850 DEG C.

Abstract: 1417900 Monitoring communication networks BURROUGHS CORP 24 July 1973 [29 Dec 1972] 35174/73 Heading H4L [Also in Division G4] A microwave communication network is divided into districts 25, 23, 27 ... each containing a district processor 13 and (terminal, two- and three-way) monitors 17, 19, 21 arranged at the nodes of the network (e.g. at radio relay stations), all the processors 13 being monitored by a central controller 11. Each monitor can handle 416 station-status indications and can control 64 station functions and has limited decision-making capability. Each district is supervised by two adjacent processors alternately, e.g. processors N and N + 1 for district 23. 600-bit message "groups" are sent from processor N to processor N + 1, each monitor inserting status information, and the message groups are stored in processor NH. The procedure is then repeated in the opposite direction. As a result of the information provided by the monitors, either the processors or the central controller then determine any corrective action required and insert commands for a particular monitor in the next message. The message group for a specific monitor is shown in Fig. 7, where ADD=binary station address of the specific monitor; CONTROLS = binary signals to control 64 relays; CONTROL RESPONSE = 64-bit representation of the contents of the local register in the monitor; FAULT ALARMS = 416-bit representation of the alarm states of the monitor. EXC, CRI and FAI indicate the nature of the data in fields 5, 7 and 9. SOH, STX and ETX are ASCII start, text and stop signals. Examples of the processor and monitors are described with reference to Figs. 2-6 (not shown).

Title: Improvements in or relating to substituted indoles
Inventor: HOFMANN ALBERT
IPC: C07D209/08
Filed: 1961-10-02
Abstract: The invention comprises compounds having the general formula <FORM:0938903/IV(a)/1> wherein R represents an alkyl radical containing 1 to 4 carbon atoms, or an aralkyl radical containing 7 to 10 carbon atoms, and R1 represents an alkyl radical containing 1 to 4 carbon atoms, or a benzyl radical.  The invention also comprises a process for preparing the compounds of formula I wherein a compound of general formula <FORM:0938903/IV(a)/2> is decarboxylated, and a process for preparing the compounds of formula Ia wherein a compound of formula I is alkylated with an alkylating agent containing 1 to 4 carbon atoms or benzylated with a benzyl halide.  The indole-2-carboxylic acids mentioned above can be prepared from an appropriate 2-nitro-6-alkyl (or aralkyl) thio-toluene in the following manner:-the substituted toluene is condensed with a dialkyl oxalate in the presence of an alkali metal alcoholate to form an alkali metal enolate derivative of a substituted phenylpyruvic ester which is saponified to the corresponding phenylpyruvic acid whereupon the required indole-2-carboxylic acid compound is obtained by cyclising in the presence of sodium dithionite (Na2S2O4) or ferrous hydroxide.  Alternatively, in the above process, the phenylpyruvic ester enolate may first be cyclised and then saponified to yield the required indole -2-carboxylic acid.  The substituted toluenes used as starting material can be obtained by diazotising 2-nitro-6-amino-toluene, and reacting the product with an appropriate mercaptan.  In Example 1, 2-nitro-6-amino-toluene is diazotised, and then reacted with methyl mercaptan in the presence of copper bronze giving 2-nitro-6-methylthio-toluene which after treatment with diethyl oxalate and potassium ethylate in ether, and subsequent saponification yields (2-nitro-6-methylthio-phenyl-pyruvic acid on acidification.  The product when treated with sodium dithionite and sodium hydroxide, and then acidified yields 4-methylthio-indole-2-carboxylic acid which heated under reduced pressure at 260-270 DEG C. and then distilled gives 4-methylthio-indole.  In Example 2, 4-benzylthio-indole is obtained by treating diazotised 2-nitro-6-amino-toluene with benzyl mercaptan, and then proceeding in a manner analogous to that described in Example 1.  1-Methyl-4-benzylthio-indole is obtained by treating 4-benzylthio-indole with methyl iodide and potassium amide; 1-benzyl-4-benzylthio-indole is similarly obtained using benzyl bromide instead of methyl iodide.  The 4-alkylthio (or aralkylthio)-indoles may be used as odoriferous substances, as intermediates in the production of indole compounds, and for attracting or repelling insects.
