Abstract: 826,824. Automatic control systems for cathode protection arrangements. MATHIASTHESEN-WERFT VEB. April 24, 1958, No. 13029/58. Class 38 (4). A ship in dock is protected from electrolytic corrosion by passing current between an anode formed by a steel cable on the floor of the dock and the hull of the ship, the current being automatically controlled to maintain the potential between the hull and a test cell between 830 and 850 mV. Direct current is supplied to the cable and the hull 2 by a rectifier 11 energized from A.C. mains RO through a variable resistor 9 which may be adjusted by a reversible servomotor 7. The potential between the hull 2 and a copper/copper sulphate electrode 1 is measured by a mirror galvanometer mV and any deviation from the required value causes light to be reflected on to one of two photo-cells 4c which control the motor 7 through an amplifier 5 and relays 6. Contacts 3a at either end of the resistor 9 energize an alarm 3b if the limit of control is exceeded.

Abstract: 550,673. Course recording apparatus; maps. MASON, W. H. Oct. 9, 1941, No. 13040. [Class 97 (ii)] [Also in Group XV] The position, speed, and direction of aircraft, ships, &c, are determined by an apparatus comprising a globe map which is so mounted and actuated as to maintain its alignment or relative position with regard to the earth constant, and means for viewing the globe in the direction of gravity. A vertical ring 5 having a lens 5a at its uppermost part is carried by a stand 9 mounted so as to be rotatable in azimuth. Pivoted to the ring 5 is a second ring 8 carrying the globe map 7. The map 7 contains two gyroscopes 10 driven by a motor 11 the gyroscopes and motor being mounted on a clock casing 12 the assembly allowing rotation of the globe map 7 about its polar axis. The clock movement is geared to the casing 12 and drives a shaft 14 which is fixed to the globe map. The result is that the globe map maintains polar and geographical alignment with the earth and the centre of the lens 5a denotes the position of the aircraft at any time the speed and direction of which may be deduced from its position in relation to the globe map 7.

Patent GB-132527-A (GB)
IPC: B24B47/10
Abstract: 132,527. Blau & Co. Aug. 8, 1917, [Convention date]. Driving and jeed devices.-In a grinding-machine in which the speed of reciprocation of the work-table is dependent on the speed of rotation of the work, means are provided for preventing the use of too great speeds of the work-table. The lever A serves to operate the change-speed gear of the work-driving means, and the lever B to operate the change-speed gear of the work-table reciprocating means, eight positions being provided for the lever A and four for the lever B. In order to prevent the maximum work speeds, corresponding to positions 7 and 8 of the lever A, from being employed when the lever B is in position IV, corresponding to maximum table speed, the lever A has pivoted thereto a rod D carrying a stop-ring E and entering a tube G pivoted to the lever B; thus, when the lever B is in position IV, the lever A cannot be moved past position 6, since the ring E is then in contact with the end of the tube G.

Abstract: 1,199,191. Self-adjusting drum brakes. GIRLING Ltd. 15 March, 1968 [21 March, 1967], No. 13282/67. Heading F2E. In a self-adjusting drum brake generally similar to that described in Specification 1,095,043 having alternative power service and manual auxiliary braking, the threaded adjustable strut, by which the manual thrust is applied between the shoes, is " wound on " by the ratchet and pawl only when the service brake is operated and so relieves the return spring pressure (and hence the friction) on the screwed strut. The ratchet and pawl may be set by the application or release of the auxiliary brake. In one embodiment. Figs. 1, 2 (not shown), the auxiliary brake lever (4) is operated by a link (15) projecting through the back plate (instead of a cable). In another embodiment Figs. 5, 6, a cross-pull lever 120 is mounted at the top of a shaft 121, journalled at its lower end in a bracket 122 and intermediately in a sliding block 123 which is recessed to take the end of the strut 6. The pawl comprises a bellcrank, on the rod 121, having one arm 113 engaging a hole in the brake-shoe web. In a modification, Figs. 5a, 5b (not shown), the cross-pull-lever 120 abuts a pin in a forked arm on the backplate. For servicing the pin is removed allowing further movement of the arm 120 and consequent relaxation of the return spring.

Abstract: 133,303. Dumanois, E. P. Oct. 4, 1918, [Convention date]. Starting. - Carburetted air under pressure is admitted at 1 and directed bv a rotary-disk valve 4 to pipes 7 leading through check-valves to several of the cylinders of a multi-cylinder engine, and the mixture is subsequently ignited to start the pistons. The mixture may be supplied by a hand-pump and cut off before the shaft begins to rotate.

The diskvalve is normally held away from the seat 6 by a spring 9, but is kept in contact with the seat, for charging the cylinders at starting, by the fluid pressure in the easing. This pressure is afterwards released through small orifices 18. which also serve to drain away oil from the bearings 12, 13 of the driving-shaft.

This pressure pivots base plate 24 against the action of springs 33 so that a part 71a of a bifurcated member 71 acts on a tab 73 to pivot arm 74 which lifts the locating pins 26 forming part of an "M" spring 79 clear of the base member. In addition a second part 71b of the bifurcated member engages arm 42 to raise it out of latching engagement with a detent 41 which held transparent rotatable plate 37 in a position such that an unobscrued part thereof is in alignment with windows 19, 21 and also to actuate switch contacts 82-84 whereby motor 62 is energized to drive rotatable plate 37 via belt 39. The plate carries pick up arm 44 on a pin 57 in a resilient mount and the arm includes a piezzo-electric pick up stylus 48anda spring 58 which tends to pivot the arm such that at commencement of play the stylus is aligned with the inner groove of the record and in play tracks outwardly. The output of the transducer is applied via rotating contacts which engage conducting parts of the plate support spindle to an amplifier 67 and speaker 66. Release of downward pressure on the device switches off the drive motor. In a second arrangement the window is replaced by finger openings for reading of Braille characters.

Title: Method for treatment of ores by magnetic sedimentation
IPC: B03C1/00
Filed: 1963-04-04
Abstract: A process for treating an ore containing a constituent capable of acquiring magnetic susceptibility as a result of reduction or oxidation comprises subjecting the ore to the action of a reducing gas for 10 to 30 minutes at 300-500 DEG  C. and, subsequently and optionally, or alternatively, according to the known chemical properties of the constituent, to the action of an oxidizing gas for 5 to 20 minutes at 200-400 DEG  C., whereby at least a part of said constituent is converted into a magnetically susceptible oxide, treating the material obtained with NaOH solution at about 130 DEG C. and submitting the resultant mixture to the action of a magnetic field to separate the magnetically susceptible oxide contained therein.  The ore may contain Fe and/or Al, Mn, Ni, Co, Cu, Mg or Zn or it may consist of metallic residues e.g. blast furnace dusts, roast pyrites, slurries or muds derived from the Bayer process, or metallurgical coke.  The reducing gas may be H2, CO, natural gas, or gases from gas generators or from blast furnaces.  Air may be used for oxidation. Reduction and/or oxidation, which may only be partial, may be carried out in an inclined tunnel or rotary furnace.  In an example, a -Fe2O3 in red muds was reduced by means of coke oven gas and oxidized by air to g -Fe2O3.  The treated red muds were agitated in NaOH solution and subjected to a magnetic field of 1000 gauss generated by an electro-magnet under the container. The oxides were removed after decantation of the sodium aluminate liquors, washed, and dried.  In another example, ferrous oxide in tungsten ore is oxidized to g -Fe2O3. The magnetic separation may be carried out using an endless belt, of a material resistant to hot conc. NaOH solution, having a plurality of electromagnets located on the upper strand of the belt, or, alternatively, by permanent magnets arranged outside or embedded in the belt. a -Fe2O3 in ores may also be converted into magnetite.
