Title: Production of carbonaceous metal ore pellets
Inventor: KENNETH JOHN GILBERT
IPC: C22B1/24
Filed: 2008-06-06
Abstract: A process for producing metal ore pellets from a particulate carbon-based material, a metal ore material, and a silicate-based binder which includes one or more surfactants, comprising the steps of : admixing the materials and binder, and agglomerating the so-formed mixture by tumbling to form the pellets at ambient temperature. The tumbling action, such as in a rotary drum, serves to agglomerate the particles and bind the mixture into the pellets. No mechanical compression force is required. The process provides a simple but efficient process for using waste carbon-based materials and waste metal ore materials, and forming a useable product, which is ready for smelting. Rotating drum or pan agglomerators are relatively low cost to build, and are capable of very high tonnage throughputs.

Inventor: ARNING ANDREAS
IPC: G06F11/36
Filed: 2009-02-13
Abstract: When test cases cause a computer program to fail, system information, such as a stack trace, is collected. The information is stored in a problem signature database along with a description of the test case that caused the failure. If the program fails when being used normally, the equivalent system information is collected and compared with the system information in the database.

Title: Monitoring apparatus for a moving fibre sliver at a drafting system of a textile machine
Inventor: CORRALES PEDRO
IPC: D01H13/16
Filed: 2009-04-24
Abstract: A monitoring device 12 for a moving fibre sliver 7 comprises a deflecting element 12b, which is arranged to be deflected by the tensioned fibre sliver. Movement of the deflecting element upon loss of tension is monitored and may initiate a switching operation or produce an inductive pulse (figure 5). A tube 16 may have a slot receiving a number of deflecting elements each corresponding to a sliver. The tube may have one pole of a voltage source connected to it and the other pole may be connected to a counter-element 12a. When under tension the sliver maintains a gap "a" and upon loss of tension the deflecting element closes the gap completing the electrical circuit. Alternatively, movement of the deflecting element may cause an inductive pulse. The deflecting element may be a leaf spring or may have a compression spring (20, figure 4) located at one end. Preferably the monitoring device is used at a drafting system of a textile machine, for example, a draw frame, card, combing machine or the like, and is arranged in the vicinity of or within a device for feeding at least one fibre sliver 7 to the drafting system to detect breakage of the sliver.

Title: Improvements in or relating to aircraft guiding systems
IPC: G01S1/02
Filed: 1945-04-20
Abstract: 594,484. Directive radio signalling. PRITCHARD, H. C., WILLIAMS, F. C., and UTTLEY, A. M. April 20, 1945, No. 10049. [Class 40 (v)] [Also in Group XXXVIII] In an indicating system wherein a variable is maintained by manual control at a predetermined value, the indication is made dependent on the displacement of the variable plus its rate of change of. displacement from the predetermined value. The invention is described in connection with an aircraft landing system, in which a hornitig aircraft at A, Fig. 1, has receiving equipment including a centre-zero meter fed with a voltage proportional to the distance x of the aircraft from the runway R, the null reading of the meter indicating that the aircraft is flying on the correct course 2 in azimuth. The arrangement may be duplicated for guidance in elevation relative to a glide path beam. The voltage v proportional to x is fed from the aircraft receiver 4 to the control grid of amplifier tube V 1 the anode of which is connected through a neon tube N and resistance R4 to the control grid of cathode followed V2, the output of which is fed back to V1 over a resistance R(i. The centre zero meter M is connected between a tapping in potentiometer R3, R8, R7, R9 and earth to which the control grid of V2 is connected through a condenser C. dv The current flow in C is proportional to dt so that the voltage at the anode of the neon tube N connected to R4 is proportional to dv v+k.- where k is dependent on the values of dt R4 and C. The meter M is adjusted to zero in the absence of any input signal and will only dv deflect when v +k.- is other than zero, i.e. when dt the aircraft goes off course. A condenser C2 may be connected across R(i to reduce' the effect of parasitic H.F. components due, e.g. to the split-frequency of the radar beam. Where the voltage v is in the form of short pulses at the split frequency smoothing may be effected by a resistance inserted in the control grid input circuit to V2 and a condenser connected between the negative side of the neon tube N and the grid side of the resistance. The voltage v fed to V1 may alternatively be proportional to the angle #, Fig. 1.

Title: Improvements in or relating to the manufacture and production of alkyl halides
IPC: C07C17/093
Filed: 1935-04-01
Abstract: Alkyl halides are produced by reacting aliphatic ethers with halogen-substituted organic compounds containing one or more halogen atoms attached to carbon atoms which are not adjacent to carbon atoms carrying hydrogen.  Suitable halogen compounds are chloroform, carbon tetrachloride, methylene iodide, monofluortrichlormethane, difluordichlormethane, benzal chloride, benzotrichloride, naphthylmethylchloride, and mono-, di- and tri-chloracetic acid. Suitable catalysts are those having a hydrating or dehydrating action, such as oxides of barium, zinc, aluminium, silicon, titanium, zirconium and thorium, aluminium sulphate, aluminium, iron, cerium, silver and uranium phosphates, and zinc tungstate and chromate.  With dimethyl ether any desired pressure may be employed, but with ethyl and higher ethers it is preferred to use pressure such as 10--30 or even 100 atmospheres to avoid production of olefines.  When the starting materials are difficultly volatile reduced pressure may be employed.  The temperature may be 200--500 DEG  C.  A small proportion of alcohol and/or steam may improve the action of the catalyst.  In examples: (1) methyl chloride is made from dimethyl ether and chloroform with alumina gel as catalyst; (2) ethyl chloride is made from diethyl ether and chloroform, using cerium phosphate gel; (3) methyl chloride is made from carbon tetrachloride and dimethyl ether, using a mixed catalyst consisting of iron, cadmium, and aluminium phosphates; (4) methyl iodide is made from methylene iodide and dimethyl ether, using alumina; (5) benzaldehyde and methyl chloride are made by passing benzal chloride and dimethyl ether over alumina gel; the benzaldehyde is collected in a catch pot at 120 DEG C. and the methyl chloride may be collected in warm aniline; (6) benzaldehyde and ethyl chloride are made from benzal chloride and diethyl ether; (7) methyl chloride, benzoic anhydride, benzoic acid and methyl benzoate are made by passing benzotrichloride and dimethyl ether over precipitated alumina; (8) methyl chloride is made by passing trichloracetic acid and dimethyl ether over phosphates of iron, cadmium, and aluminium; (9) methyl fluoride and chloride are made by passing monofluortrichlormethane or difluordichlormethane and dimethyl ether over alumina.
