Abstract: 978,690. Unwinding bobbins &c. BRITISH OXYGEN CO. Ltd. Dec.17, 1963 [March 21, 1963], No. 11250/63. Heading D1J. A mechanism for de-reeling wire or the like from bobbins has a hollow shaft 10 that is co-axial with the bobbin axis, the shaft 10 having attached thereto an arm 13 that is movable about the bobbin axis and carries pulleys 18, 19, 20 to guide the wire from its take-off point as this moves around the bobbin. The pulleys 18, 19, 20 guide the wire to the hollow shaft 10 and the wire 10 then passes up the shaft 10 to a take-off pulley 23. Slackness in the wire, caused by over-running of the pulleys, is prevented by a braked disc 28; and resilient means 32, 33 are included to permit a limited relative rotation between the shaft 10 and the disc 28. According to the invention the resilient means 32, 33 are springs arranged to act in opposite directions of rotation to give substantially equal resilience in either direction of rotation, and the braked disc 28 is arranged to exert a braking effect that is not dependent on the direction of rotation. As shown the springs 32, 33 are coil springs mounted so as to be of opposite hand and during attachment they are pre-stressed in opposite directions of rotation. The braking device is a plate 37 that is mounted at one end on a hinge 36 and carries at its other end two blocks 38 that are bored to slidably receive two braking pads 39 engaging opposite faces of the disc 28. These pads are biased into contact with the disc 28 by pivoted levers 40 acted on by a spring 43. Screws 44 are provided to give a coarse adjustment of the braking effect exerted by the pads 39. The position of the plate 37 about the hinge 36 may be adjusted by screws 45 to give a fine adjustment of the braking effect exerted by the pads 39.

Title: Improvements in or relating to apparatus for supplying electric oscillations
Inventor: WEST GORDON MAURICE
IPC: H03B21/04
Filed: 1963-03-22
Abstract: 1,058,791. Frequency changing systems. GENERAL ELECTRIC CO. Ltd. March 20, 1964 [March 22, 1963], No. 11431/63. Heading H3F. An electrical oscillation generator comprises a cascade of units each including three frequency changers such as 14/1, 14/2 and 14/3 arranged in a ring each to mix an input oscillation with the output of the previous frequency changer to provide an output for the next unit which varies in frequency only half as much as the variation of frequency of one of the input frequencies. Thus, in the Figure, the variation in frequency input to 17/1 by switching 25 produces half that variation at the output 17/3. Similarly operating switch 24 produces a quarter of the variation, 23 produces an eighth and 22 a sixteenth so that the output frequency can be changed in sixteenths of the difference between the two oscillations 20, 21 in accordance with the binary code set up by operating the switches. These switches may be replaced by relays or diodes so that the frequency may be set up in accordance with a binary code derived from a computer. If the input frequencies are suitably chosen then the output from each unit when the switches 22-25 are in one position is equal to the frequency of 18. The output from units 14/1, 15/1 &c. is approximately equal to the frequency of oscillation source 19 and in Fig. 4 (not shown) decimal divisions of frequency are obtained in an arrangement in which the oscillations for 15/3 and 16/3 are derived from the output of 17/1. Three groups of units are provided to provide three decimal levels and the various frequency inputs are derived from a common oscillator source by way of a harmonic generator and appropriate filters. In a further arrangement (Fig. 5, not shown), the oscillation input to the left-hand frequency changers are variable in ten steps so that three decimal levels of setting are possible. The decimal variations in frequency of each oscillation source may themselves be provided by an arrangement similar to Fig. 3, but having only three stages and in which the input to the righthand frequency changer of the third stage may also have alternative values.

Filed: 1944-06-22
Abstract: The siliceous, lime-containing slag, resulting from the reduction of bituminous shales to recovering metals therefrom, (see Group II), is treated to obtain aluminium and potassium values contained in it by finely grinding the slag and leaching with acids.ALSO:A process of treating bituminous shales for recovery of one or several of the metals vanadium, molybdenum, tungsten and titanium contained therein, as well as iron, comprises heating such a shale in the presence of air to lower its sulphidic sulphur content by oxidation, fusing the said roasted shale under reducing conditions with basic slag-forming materials in quantity sufficient to lower the viscosity of the slag formed in the fusion step but not exceeding a quantity of 60 per cent. by weight of the slag, preferably 10-25 per cent., calculated as calcium oxide, to form a metal bath and a siliceous slag bath, separating the metal bath and recovering metal values therefrom.  The content of reducing agents in the fusion mixture should be adjusted to correspond to from 1-5 times the quantity required for complete reduction of the metal oxides of iron, titanium, vanadium, molybdenum and tungsten contained in the said mixture.  Such adjustment may be effected by addition of carbonaceous materials, e.g., coke, and/or other reducing agents such as ferrosilicon or by addition of reducible oxides, such as iron oxides in the form of iron ore, to the fusion mixture.  The slag bath separated from the metal bath may be treated to obtain mineral values therefrom (see Group III). The shale used in the process may have been previously treated for the recovery of oil therefrom.  The production of a metal bath containing iron 78 per cent., silicon 13.6 per cent., vanadium 5.21 per cent., titanium 1.5 per cent., molybdenum 0.25 per cent., manganese 0.5 per cent. and phosphorus 0.7 per cent. is described.
