Title: Process for refining crude copper
IPC: C22B15/00
Filed: 1933-06-06
Abstract: A process for refining crude or impure copper consists in causing a violent intermixing and turbulent emulsifying of the molten metal and a very fluid oxidizing slag containing a copper compound capable of reacting with the impurities to be eliminated, the process not requiring the application of external heat.  The metal is rapidly poured, as, for example in a thick jet from a considerable height on to the slag in a ladle, or mechanically agitated with the slag as by movement of a suitable container or p  by gaseous means.  The slag may be acid or basic and may contain fluxes and copper oxide, sulphide, silicate, or chloride, &c., or roasted copper ore.  The metal may be treated successively with the same kind of slag or with acid and basic slag in either sequence.  The slag is preferably prepared by fusion in a water-jacketed furnace.  The Specification as open to inspection under Sect. 91 comprises also intermixing the slag and metal by agitating by means of an electric field.  This subject-matter does not appear in the Specification as accepted.

A digital storage arrangement comprises a number of stores, one for each character in a message. During storage, the first character of a series of characters is stored in the first store, the second in the second store, and so on. During read out, the characters are read from the first store only, characters in higher stores being shifted to the next lower store as that store becomes empty. The embodiment described comprises relay stores, each character being handled as a 5-bit parallel signal. The stores are interconnected so that the characters are automatically read in to the correct stores and so that the data is automatically shifted downwards following each read out pulse applied to the first store, no external control being required.

[Also in Division G2] Apparatus for detecting cracks in transparent articles by reflection of light from the cracks comprises a number of bundles of optical fibres for conducting light to a test area on the article and/or from the test area to a receiver. The bundles are preferably arranged in the form of a truncated cone having its virtual apex at the test area which may be rectangular. If there be illuminating and receiving bundles, a light chopper may be arranged to pass light to each illuminating bundle in turn, and simultaneously mask any receiving bundle which is in a position to receive light directly from the illuminated bundle without reflection from a crack. The receiving bundles may be omitted and light reflected from the crack received by an annulus of photo-cells so positioned as not to receive light directly from the illuminating bundles. The apparatus may be used to inspect glass or plastics sheets or the sides, bottoms or necks of vessels which are preferably rotated during inspection. The photo-cell output may operate a rejecting device.

Abstract: 1392351 Reversible ploughs P VIAUD & CO 11 April 1972 [16 April 1971 (2)] 16634/72 Heading A1B A semi-mounted one way reversible plough comprises a tool beam 3 which has two sets of liftable plough shares arranged in a fish bone pattern thereon and which is moved in a horizontal plane about a pivot 4 by two jacks 8, 8' whose control mechanism also causes the right hand plough shares to be lowered or lifted whilst the left hand plough shares are raised or lowered according to the orientation of the beam 3. The front end of the beam 3 slides in a guide piece 6 mounted on a central beam 5 to which is articulated an oscillatory coupling head 7 for coupling the plough to a tractor (not shown). The head 7 is connected to the guide piece by way of two U-shaped members (Fig. 3) (not shown) located at respective ends of the guide piece 6 so as to receive the end of the beam 3, and thereby incline the plough relative to the coupling head 7 so as to maintain the operative plough shares in a vertical working position by compensating for the inclination of the tractor due to its wheels being in a furrow. The tool beam 3 is supported at its rear end by ground wheels 16 which are aligned with respect to the direction of travel by a linkage 18, 18'. Each plough share is raised or lowered by a respective single acting hydraulic jack 44 acting on a two part, articulated thrust bar 45, 47, the two parts being biased into substantial alignment by a spring 43. A screw 42 permits the included angle between parts 45, 47 to be adjusted to alter the force necessary to overcome the spring. On encountering an obstacle the thrust bar folds and the share lifts over the obstacle. The jack may be double acting.

Abstract: 169,170. Vermehren, J. Sept, 14, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Multiplying and dividing apparatus.-In multiplying apparatus provided with two groups of keys for setting both factors and on which the factors remain set during and after the calculation has been effected, the setting of the multiplicand on the keys 1, Fig. 1, by depression of the appropriate keys effects the selection of a pair of nine transmitting pinions 2, 3, mounted on spindles D, C and adapted to be subsequently actuated by a selected pair of gear-wheels of a corresponding group of nine groups of gear-wheels a<1> - - a<9>, b<1> - - b<9> having teeth representing the products of the digits 1 - - 9 by themselves in units and tens. The nine groups of gear-wheels a, b are mounted on spindles A, B in a sliding carriage 13 which is displaced on the operation of the machine to an extent depending on the particular multiplier key 4 depressed so as to bring the selected pair of gear wheels into the path of the transmitting pinions 2, 3. The stem of each multiplier key passes through a bar 8, and when a key is depressed projects into a recess 6 in a plate 7. The bar 8 is provided with a pin engaging a cam groove 9 in a disc 10 which on the operation of the main handle is rotated to cause the bar 8 and plate 7 to reciprocate, the extent of movement of the plate 7 depending upon the key which is depressed as the various recesses 6 are of different length. The plate 7 by means of a pivoted lever 11 displaces the sliding carriage 13 and thereby positions the groups of gear-wheels a, b. The operation is effected by a series of wheels 14 - - 18 having teeth on one-fifth of their periphery and adapted to engage pinions 24 on their corresponding discs 10 in succession to effect the displacement of the plates 7; the spindles A, B are then rotated in succession by means of worm-wheels 19, 20, the motion being communicated through the selected transmission pinions 2, 3 and shafts C, D to the totalizing counter. In a modification, instead of providing two transmitting spindles C, D a single spindle may be employed having pinions thereon which would be rotated by the gear-wheels on the spindles A, B in succession.
