Title: Treatment of killed steel
Inventor: HAMMERTON RODERIC HUGH
IPC: B22D1/00
Filed: 1968-09-05
Abstract: 1,249,324. Casting processes. FOSECO INTERNATIONAL Ltd. 4 Sept., 1969 [5 Sept., 1968], No. 42225/68. Heading B3F. A method of treating ingots of killed steel comprises introducing cadmium into the molten steel after teeming has ceased. The cadmium can be introduced as a block of cadmium impregnated sponge iron. In the example, 114 gm. blocks of cadmium were added to moulds for 5-ton ingots. The cadmium evaporates leaving bubbles in the ingot which compensate for shrinkage of the ingot on cooling. Immediately after cadmium addition the ingot is capped by placing a cast iron plate on its upper surface. The capping plate can be further cooled by spraying with cold water.

Title: Label feed for a device for printing and/or dispensing self- adhesive labels
IPC: B41K3/00
Filed: 1970-09-03
Abstract: 1327057 Label feed METO-GESELLSCHAFT OSCAR KIND mbH 3 Sept 1970 [4 Sept 1969] 42239/70 Heading B8F [Also in Division B6] A label feed device for a label printer and/or dispenser comprises a transport roller 4 provided with peripheral projections which engage recesses (not shown) in the edges of a carrier tape 2. A pawl like device 7 is pivoted about pin 18 and bears a pin 19 engaging a slot in a member 15 attached to the handle 13. On operating the handle 13 the pawl device 7 rotates anticlockwise and a pair driving abutments 20 ride over a set of projections on the roller 4. Subsequent release of the handle causes the pawl to revert to its original position by clockwise rotation, the driving abutments engaging behind the roller projections to drive the roller and advance the carrier tape 2. During the driving motion a gripping piece 8, integral with the driving abutments 20, engages the carrier tape to press it against the periphery of the roller 4, thereby preventing slipping of the carrier tape 2. The edge of the gripping piece 8 may be of resilient material. The gripping piece and driving abu - ments are pivotally secured between side members of the pawl device 7 and are spring biased to rotate clockwise as shown in Fig. 1. A spring 21 engaging teeth on the roller 4 prevents anticlockwise rotation of the roller. In the embodiment shown a label printing station 6 is inked by a pad 16, the pad swinging away when the handle 13 is operated to allow the printing head to press on the label on platen 5. A label 1 is separated from the carrier tape 2 at roller 10. A curved plate 31 may be provided to act as a "funnel" when introducing a new tape to the machine. Alternatively the pawl device 7 may incorporate an inwardly tapering guide on the infeed side of the roller 4 to assist engagement of the tape on the roller. The feed device may be incorporated in a motor driven printing and/or dispensing apparatus, but is intended for use with backed or supported self adhesive labels. The label stock may comprise discretelys paced individual labels, or may comprise a continuous label tape backed. by a carrier.

[Also in Division C7] A process for the recovery of Group III B  (Y, Lanthanides U and Th) and Group V B  (Nb and Ta) metal values from euxenite ore comprises reducing the ore by the heat of reaction between a charge of metal and an oxidizing agent to form an upper molten layer containing the Group III B  metals in a slag which is separated from a lower molten layer containing the Group V B  metals alloyed with iron which if necessary is added to the ore prior to the reduction. The metal charge is preferably magnesium and/or aluminium and the oxidizing agent is preferably sodium chlorate. In the preferred form of the process the ore is mixed with the powdered metal, oxidizing agent and sufficient iron to form ferro-niobium and ferro-tantalum and the charge is then ignited to initiate thermite reduction. The mixture of ore metal charge oxidizing agent and iron may be formed into briquettes prior to ignition. The slag after solidifying is leached with an aqueous solution of a mineral acid preferably 4 to 16 molar HNO 3  containing 0À02 to 0.05 moles of HF per litre, the acidulated slag is subjected to solvent extraction to dissolve uranium in the solvent and leave an aqueous raffinate containing the other metal values. The extracting solvent is preferably tributyl phosphate but tri-n-octyl phosphine oxide, hexone, or ethyl ether may be used. The urania is separated from the solvent fraction, concentrated, denitrated and converted to the oxide. The pH of the aqueous raffinate is adjusted to between 3 and 4 preferably with ammonia and thorium hydroxide is precipitated and filtered off. The other metal values are recovered by precipitation with sodium carbonate.

Abstract: 1381520 Character recognition systems DE STAAT DER NEDERLANDEN TE DEZEN VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE 25 Sept 1972 [23 Sept 1971] 44248/72 Heading G4R A postal item bearing an address code which is to be machine read undergoes a coarse scan, to determine the position of the code, followed by a fine scan of the code. When the leading edge of the item reaches the field of scan a light flash is generated to produce a stationary image on a television type camera tube. The image is scanned in a coarse horizontal raster. The signals generated during each line scan pass to a unit which delivers a pulse when a character portion is scanned. The pulse gates the output of two counters, fed from the camera tube deflection circuits, to provide the x, y co-ordinates of the first character portion scanned in the scan line. The co-ordinates obtained during successive scan lines feed a unit which determines the vertical centre of each row of characters on the postal item, and the leftmost portion of the first character in each row. From the known format of the address it will be known which row or rows contain the address code or codes. The vertical centre signal of the required row controls the bias on the vertical deflection coil of an image dissector tube. As the postal item passes before the dissector tube a sawtooth deflection voltage causes vertical deflection of the image about the centre of the row, providing a fine raster scan of the characters in the row. When the left-most portion of the first character in the row is in the field of view of the dissector tube, signals are generated indicative of the black/white variations in the present scan line of the fine raster. These signals are stored at an address corresponding to the line number, for subsequent processing.
