Patent GB-848374-A (GB)
Title: Improvements in the production of cell feed solutions for the electrowinning of manganese
IPC: C25C1/10
Filed: 1958-09-10
Abstract: In the production of cell-feed solutions for electrowinning of manganese from slags, the slag is leached with an aqueous sulphuric acid-containing liquor at a rate such as to maintain the pH of the slurry at 3.5 at least, and thereafter the slurry is neutralised to pH 6.0-6.6 with a base, normally ammonia, to precipitate silica and alumina.  The leach solution is normally recycled anolyte with make-up acid.  The solution so obtained normally contains 30-32 g.p.l. manganese, and after oxidation to remove iron, is ready for electrolysis.  The calculated quantity of sulphuric acid may be added gradually to a quantity of slag but preferably the latter is present in excess, in which case, after neutralisation the slurry of alumina and silicate precipitate in the manganese-bearing solution may be separated from the heavier excess slag which is retained as make-up for the next leach.
Patent GB-821986-A (GB)
Title: Improvements in or relating to compositions containing boron compounds
IPC: C07F5/04
Filed: 1957-09-16
Abstract: Liquid homogeneous compositions consisting essentially of from 5 to 15% by weight of 2-methylpentanediol - 2,4 - hydrogen borate and from 95 to 85% by weight of bis-(2-methylpentanediol-2,4) diborate are used as additives to motor fuel gasolines.  (For preparation see Group IV (b).)  The compositions may be added to any of the conventional gasoline base stocks which may also contain tetraethyl lead in amounts up to 6 c.c., preferably 1/2 c.c. to 3 c.c., per gallon, and a scavening agent.  The latter may be 1 theory of ethylene dichloride and 1/2 theory of ethylene dibromide (motor mix) or 1 theory of ethylene dibromide (aviation mix).  The gasoline may contain any of the usual adjuncts such as antioxidants, dyes, solvent oils and alcohols.  An amount of the composition to provide 0.002% by weight of boron (calculated on the total fuel) is the smallest amount used.  Amounts providing between 0.004% and 0.008% by weight of boron are preferred.ALSO:The invention comprises liquid, homogeneous compositions consisting essentially of from 5 to 15% by weight of 2-methylpentanediol-2,4 hydrogen borate and from 95 to 85% by weight of bis-(2-methylpentanediol-2,4)-diborate.  The compositions may be prepared by mixing the two components in the desired proportions or starting from boric acid and 2-methyl-2,4-pentanediol, in a 1 : 1-molar ratio, and controlling the reaction so that the desired blend is obtained.  Thus in the course of the reaction, the initially formed 2 - methyl pentanediol - 2,4 - hydrogen borate is converted into the bis-(2-methyl pentanediol-2,4)-diborate by heat dehydration, and, by sufficient heating, over 85% of the diborate can be obtained. The compositions are useful as additives for gasoline (see Group III).

Title: Electrical Protection Circuit
IPC: H02H3/087
Filed: 1967-06-23
Abstract: 1,188,157. Protective arrangements. INTERNATIONAL STANDARD ELECTRIC CORP. 23 June, 1967 [27 June, 1966], No. 29104/67. Heading H2K. Each output of a low-voltage D.C. supply is provided with a current limiting circuit 1-4 and an electrically releasable switch 6 responsive to the voltage drop across the current limiting device 4. Normally transistor 4 is biased by resistors 2, 3 into its conducting condition. If the current increases the voltage drop across resistor 3 increases and renders a diode 1 conducting. This alters the bias at the base of transistor 4 towards cut-off and the emitter-collector voltage rises. This voltage is applied to a trip-coil 5 and, at a predetermined overcurrent, releases the latch 8 to open contacts 6.

Title: Improvements in or relating to torque-meters in gear drives
Inventor: HAWORTH LIONEL
IPC: G01L3/14
Filed: 1947-10-01
Abstract: 654,082. Measuring torque. ROLLSROYCE, Ltd. Oct. 31, 1947, Nos. 29161/47 ond 5521/48. [Class 106 (ii)] [Also in Group XXIV] In an arrangement for measuring torque in a gear-train comprising a lay-shaft 16, Figs. 1 and 3, free for limited axial movement, and supporting a gear 15 which develops axial thrust when torque is transmitted through the gear-train, thrust bearing means 17, supporting the lay-shaft, is carried in non-rotatable axially movable housing means 30 including a cylinder element 32 in which slides a fixed piston element 130, pressure fluid is supplied to the element 32 to oppose the axial thrust and escapes through an exit port such as 138, the area of which is determined by the relative position of elements 32, 130, and the pressure in the cylinder element is measured, e.g. by a gauge 42, Fig. 4, calibrated to indicate torque. As shown, the torque transmitted through reduction gearing between a gas-turbine engine and an airscrew is measured. The engine drives a helical-toothed pinion 12, Figs. 1 and 4, meshing with three helical gears 15 or 40 on shafts 16 or 41 which also carry straight-toothed gears 19 meshing with an internally toothed ring 20 supported to allow limited play transversely to its axis on a flange 23 carried by the airscrew shaft 24. Only one of the shafts 16 or 41 has the housing means 30, Fig. 3, fixed to the outer race of the thrust ball bearing 17, and the associated piston and cylinder, the space between which is sealed by rings 135, 136, and supplied with fluid through ports 140 by a gear pump 37 driven by the shaft. The area of escape ports 138 is controlled by cylinder ring 136, the cylinder moving until this area is such that the fluid pressure balances the axial thrust. Assuming equal torque transmission through each shaft 16 or 41, the total torque and thus the total power transmitted through the gearing can be obtained. In a modification, the play between the ring 20 and flange 23 is eliminated and there is a piston-and-cylinder device for each shaft 16 or 41. Only one device, however, may have the controlled exit ports 138, the gear pump driven by the corresponding shaft supplying equal fluid pressure to all three devices. Where the gears transmit different proportions of the total torque the effective thrust areas of the corresponding piston-andcylinder devices are dimensioned accordingly.
