Title: Improvements in and relating to processes for the production of ferro-manganese
IPC: C21C7/00
Filed: 1935-03-28
Abstract: Manganese ores or slags containing too large a proportion of iron to permit of being worked up to ferro-manganese in one stage are melted, after the addition if necessary of fluxes, e.g. limestone, fluorspar, or sand, to form a neutral or slightly acid and low-melting manganous oxide slag, and so much iron is reduced, as by means of charcoal, at a temperature below the reduction temperature of the manganese, as to form an intermediate product possessing an iron-manganese ratio required for producing the ferro-manganese desired.  The basicity of this product is then increased by the addition of lime and on increase of temperature it is reduced to ferro-manganese.  The two stages may be effected in one or separate furnaces.  The iron reduced from the manganous oxide slag may be continuously or intermittently removed.  In an example an ore containing 31,1 per cent of iron and 17,8 per cent of manganese are melted with a flux and by the addition of reducing charcoal so much iron is reduced at 1300-1400 DEG  C. as to leave a manganous oxide slag containing 5,2 per cent of iron and 25,9 per cent of manganese.  Lime and reducing charcoal are added to this slag which is reduced at about 1600 DEG  C. to ferromanganese containing 11,4 per cent of iron and 79,1 per cent of manganese.

Abstract: 849,168. Electric selective signalling systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 12, 1958 [March 26, 1957], No. 9836/57. Class 40 (1). In a device, Fig. 1, for producing a digital representation of the position of a linearly movable member S, its " coarse " position is obtained by means not shown and its " fine " position is obtained by observing on which vertical column of a coding mask C a strip of light from a lamp L and via one of a number of slits in the member S, falls. The coding mask is scanned, in a vertical direction by a photo-electrical arrangement including a mirror G oscillating about an axis normal to the plane of the paper, and as a result a series of pulses emerges from a clipping circuit CC corresponding to the transparent portions of the mask. The first two channels 1 and 2, Fig. 2, of the coding mask, are coded in monophylic binary and the remainder are coded in pure binary but each is duplicated and shifted an amount 2<SP>n-2</SP> where n is the order of significance of the channel. Thus the 2<SP>2</SP> channel appears correctly phased at 4 0  and shifted (to the right) by two divisions at 4 1 . Similarly the 2<SP>3</SP> channel appears at 8 0  and shifted four divisions at 8 1 . Every shifted scale is slightly modified, however, in that the first group of ones is replaced by zeros (shown crosshatched). This construction is used to eliminate errors due to movement of the member S while the coding mask is being scanned and those due to the fact that the width of the slit of light is greater than one scale division. A logical decoding circuit D, Fig. 1, is described which selects appropriate pulses from those produced by the scanning of the coded mask. Specification 717,114 is referred to.

[Also in Group XXX] An apparatus for cooking fish packed in open containers, e.g. cans C, and constrained in the cans C by grill-type carriers 11, comprises a cooking chamber 12, a dehydrating chamber 13 communicating with the cooking chamber 12, means for carrying the containers through the cooking chamber 12 in an inverted position, means for righting the cans C, means for carrying the cans C through the dehydrating chamber 13 in an upright position, and means for heating the cooking chamber 12 and the dehydrating chamber 13. Open cans of fish C are placed in trays 21, carriers 11 are inverted over them and then the entire assembly is inverted to the position shown in Fig. 2. The carriers 11 are hand loaded from a platform 28 by means of hooks 26 on to supporting pins 88 secured to two chains of a first conveyer 14 and are thence transported through a steamheated cooking chamber 10, down past the bottom of a partition 34, up through a discharge passage 39 into and then along the bottom half of a dehydrating chamber 13. A second conveyer 16 comprises two parallel chains, spaced by a distance less than the length of the carriers 11, and interconnected by flight bars 103. Three conveyer interchange and inverting rails 124 run parallel to the path of the lower half of the second conveyer 16 and both the rails 124 and the conveyer 16 incline upwardly towards a drive sprocket 104 so lifting the hooks 26 from the support pins 88 causing the carriers 11 on passing round the sprocket 104 to be transferred to the second conveyer 16 and to be simultaneously inverted hence righting the fish cans. The carriers 11 are unloaded from the second conveyer 16 by rails 131 and slide down to a discharge table 119. Steam is fed to the cooking chamber 10 through a pipe 136 and hot air is supplied by two recirculating blowers forcing air through a steam heated heat exchanger 148 into the dehydrating chamber and out through ports 149 into ducts fixed to the sides of the cooking chamber 12 which return it to the blowers. In another embodiment the carriers 11 are fed by a conveyer to a loading table from which they are raised to engage the pins 88 on the first conveyer 14 by the operation of a foot pedal. In a further embodiment an automatic hydraulically operated loading system is used and the dehydrating chamber 13 includes a longitudinally extending baffle separating the upper and lower runs of the second conveyer 16 which together with a repositioned blower is so arranged that the heated air flows counter to the direction of movement of both runs of the conveyer.

Title: Process and apparatus for improving composite metal articles
IPC: B23K31/02
Filed: 1941-08-02
Abstract: 550,879. Making valves; casting composite articles. HAYNES STELLITE CO. Aug. 2, 1941, No. 9875. Convention date, Aug. 3, 1940. [Classes 83 (i) and 83 (ii)] A composite metal article having a wearing surface of protective metal. is improved by melting the protective metal while the article is cooled, by conduction or otherwise, and then allowing the molten metal to cool so that solidification occurs progressively to the free molten surface. Aeroplane-engine or other valves 17 with protective metal 18, such as cobaltchromium-tungsten alloy, deposited thereon, may be inserted in pockets 20 each with a skirt 25 immersed in a water-bath 26 and carried by a shaft 27. Pilot burners 69 being lighted, a motor 39 is started, and fuel gas and oxygen supply to burners 62 turned on, by a handle 101, Fig. 3. The position of the burners may be adjusted by screws 56, 60. The motor acts through speedregulating gearing S, adjusted by a hand lever 4, and S<SP>1</SP>, adjusted automatically by a lever 91, speed-reducing gearing R, R<SP>1</SP>, chain-gearing,52, and toothed gearing 28, to rotate the valves at about ¢ revolution per minute or 2 to 6 linear inches of the band. 18 per minute. A shaft 73, rotated by gearing R, has a cam designed to move the lever 91, when all the metal 18 has been melted, and resolidified at least once, to progressively increase the speed of rotation of the valves, thus preventing further remelting but keeping the metal 18 hot. At this stage the linear speed of the band 18 is about 12 to 36 inches per minute. After further rotation a cam 105 on the shaft 73 trios the handle 101 to cut off the gas supply to the burners 62 and a cam 76 operates a switch 82 to stop the motor 39. The starting switch is parallel with the switch 82 and is arranged to open automatically a short time after it has been closed. Porous metal will thus be restricted to a thin surface layer which may be removed by grinding. Specifications 368,605 and 528,730 are referred to.

Title: Process for producing uranium tetrachloride
IPC: C01G43/08
Filed: 1944-05-22
Abstract: <PICT:0812121/III/1> Uranium tetrachloride is produced by reacting carbon tetrachloride vapour with an uranium oxide at 425 DEG  to 475 DEG  C.  The uranium oxide may be UO2, U3O8 or UO3, UO2 being preferred.  The reaction gases containing unreacted carbon tetrachloride, phosgene and carbon dioxide may be condensed whereby the phosgene dissolves in the condensed carbon tetrachloride and may be recycled, the chlorination then proceeding by virtue of the phosgene and the carbon tetrachloride. As shown in the drawing a reaction vessel 12 is surrounded by a tubular furnace 11 and fed with carbon tetrachloride vapour through lines 13 and 24 which are supplied with liquid carbon tetrachloride from a vessel 17 through a drop feed device 18 and a U-tube 19.  Carbon tetrachloride vaporizes in the line 13 and enters the reaction vessel through line 24 to contact the uranium oxide 14 and convert it to tetrachloride.  The reaction vessel may be shaken to prevent caking.  The reaction gases leave through a trap 25 for any uranium pentachloride formed and from thence pass to a tube 31 leading to a condenser 32.  Gases which do not dissolve in carbon tetrachloride pass through the condenser whilst carbon tetrachloride and dissolved phosgene fall through a trap 33 to be recycled to the drip feed 18 to the reaction vessel. Examples are provided illustrating the application of the invention to charges of UO2, UO3 and U3O8.

Abstract: 1,255,993. Priority circuit. RCA CORPORATION. 25 Feb., 1969 [8 March, 1968], No. 9946/69. Heading G4A. In a priority circuit, a request-for-service signal on any one of n input lines (e.g. from a peripheral in a computer system) sets a respective stage of a register, any set stage of the register causing the input lines to be disconnected from the stages, and means being provided responsive to any set stage for resetting any lower-priority set stages only. The disconnection is by disabling input gates to the stages in response to a delayed signal produced when any stage is set, this signal being further delayed to enable stage resetting gates already primed by the set states of higher-priority stages, the signal being yet further delayed to set an auxiliary stage to gate out the surviving set state indication. When the selected service request has been dealt with, all the stages are reset.
