Title: An improved process for the treatment of gold-bearing ores, residues and other products
IPC: C22B1/08
Filed: 1946-12-18
Abstract: Gold ores, residues, &c. which may also contain silver are treated by the process of Specification 635,904, and the residue from the cyanide extraction is again subjected to the same roasting and extraction treatment.  The temperature of the first roasting should however, be lower, say 700 DEG  C., and the second roasting temperature may be higher than 800 DEG  C.  The first extraction is moreover effected with a strong brine containing alkali and cyanide so that the residue for the second roasting already contains salt, an addition of solid salt being made if necessary.  After roasting the material should be cooled quickly to 500 DEG  C. to avoid volatization losses.

A load lifting and carrying apparatus comprises two spaced parallel telescopic mast assemblies 11, 12, Fig. 2, pivotally mounted at the rear end of the traction unit 10 of an articulated vehicle and movable between an out-ofuse position in which they overlie the deck of the unit and an in-use position in which they are upright. Each mast assembly comprises a channel beam 13 pivotally mounted on a bracket 15 and a channel beam (14), Fig. 4 (not shown), slidably mounted within the beam 13. The beams (14) are interconnected by cross-bars (16, 17) and a carrier plate 18, Fig. 5, is slidably mounted thereon and carries two fork members 19 which are pivotally connected at 22 to link members 20 supported pivotally at 23 on the plate 18, the members 19 in their working position abutting the lower face of the plate 18 via spacer blocks 21. The beams (14) are raised by single-acting hydraulic rams 24 and the plate 18 is raised by chains or wires (25) connected to the plate and extending over pulleys (26) to anchorages on the beams 13. The mast assemblies are pivotally moved by double-acting hydraulic rams 30 and at least one ram 32 is provided on the unit 10 to assist the rams 30 during initial upward movement of the assemblies and to cushion their downward movement. The rams are actuated by a pump coupled to a power takeoff shaft of the unit 10 or to the vehicle's engine, and operation is controlled from levers 10A within the cab of the unit; the levers 10A may be duplicated at the rear of the unit. A mechanism for lateral movement of the mast assemblies is provided, Fig. 6; the beams 13 are pivotally mounted on an axle 33 slidably mounted in brackets 34 and having a bar 36 extending therefrom through a slot in a plate 35 carrying the brackets 34, a double-acting ram 37 being connected to the bar 36. The beams 13 move laterally with the axle 33. In operation the apparatus is used to load and unload the trailer of the vehicle. When the mast assemblies are to be lowered to their outof-use position the beams (14) and the plate 18 are raised so that the beams will not extend beyond the rear of the unit 10. To prevent fouling of the vehicle's cab and a fifth wheel plate 38 the plate 18 is locked to the beams (14) at its upper position and the beams (14) are then lowered by a small amount; a spring-loaded pin 40, Fig. 7, is mounted on the plate 18 for releasable engagement in an aperture 42 in one of the beams (14), and spring-loaded friction discs 43 are provided to prevent instant movement of the plate 18 when the pin 40 is disengaged and the mast assemblies raised. The fork members may be replaced by a crane jib pivotally mounted on the plate 18, or by clamps attached to the plate by snap-action couplers and having hydraulic connections. The plate 18 may have side extensions whereby the forks are movable laterally beyond the mast assemblies.

Abstract: 1,235,900. Article dispensing apparatus. VENDO CO. 7 Aug., 1968 [15 April, 1968], No. 37621/68. Heading A4T. An insulated container 20, Fig. 3, has partitions 34 carrying rails 38, 40, 42 supporting the ends of cylindrical cans A, B to provide a number of side-by-side, serpentine, double stacks, the cans gravitating towards dispensing openings 56, 58 controlled by right-angle paddle wheels 66, cold air from refrigerator 52 circulating through the stacks. The paddles may be controlled separately through 90 degree steps or two side-by-side together secured on a common axle 70, e.g. cans A (solid lines) are-released in two 45 degree steps of the paddle alternatively with cans A (dotted lines) in the next side stack. A coin switch energizes solenoid 74, Figs. 4, 6, 11, rotating crank 86 about pivot 80 to engage rods 84 carried by paddle stops 68 pivoted at 80 and move them away from paddles 66 against spring 88. The paddles rotate 45 degrees under the weight of cans and one is dispensed, e.g. the dotted can in Fig. 3. A paddle actuates a credit cancelling switch 108 via feeler 110, the solenoid is de-energized and the stop 68 intercepts the paddles and prevents further dispensing. When one stack is empty, flap 94 pivoted at 98 falls and locks at 104, 106 a rod 102 sliding with one stop bar 84 to prevent that stop 68 engaging one paddle whereby the solenoid releases the other stop to allow 90 degree rotation of the paddles for dispensing cans until the other stack is empty. Sold out signs or arms 118 pivoted at 98 fall and via bar 116 actuate empty lamp switches 112, 114. The sold out arms may be shortened or repositiond so that one or more cans remain in the stacks.

IPC: F02K1/12
Filed: 1959-11-06
Abstract: 876,583. Deflecting propulsive jets. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Nov. 6, 1959 [Nov. 12, 1958], No. 37720/59. Class 4. [Also in Group XXVI] A substantially circular jet propulsion nozzle comprises two groups of moveable wall elements without any connecting linkage, an upstream group forming a convergent portion and a downstream group which can also form a convergent portion in continuation of the first group or else a divergent portion following the convergent portion the wall elements of the downstream group being able to carry out, in longitudinal planes, a combined translation along the axis of the nozzle and a rotation about an axis located about the middle point of the elements and substantially tangential to the nozzle. A jet propulsion nozzle, Fig. 5, comprises a plurality of upstream flaps 2 pivoted at 3 to the downstream end of the jet pipe 1. These flaps are caused to bear on the upstream ends of the downstream wall elements 4 by the gas pressure of the jet although a spring or return jack may be provided to prevent fluttering. The elements 4 have pins 10, 11 which are guided by slots 6, 7 in a plate 8 attached to a fairing 9. The elements 4 are moved by jacks 15 acting through a synchronising ring 16. Movement of the jacks 15 will cause a combined translational and rotational movement of the elements 4 and alter the shape of the nozzle from that shown to a convergent-divergent configuration. In a modification, Fig. 9, the flaps 2 and members 4 are operated by separate sets of jacks 15, 17, independently operated. With this arrangement, the flaps 2 and members 4 may be separated so as to leave an annular space for atmospheric air to be sucked in by ejector effect. It is possible to control each element or some of them separately in order to give them assymetrical positions causing deflection of the jet. The flaps 2 may be hollow and cooled by air from the atmosphere or by air from the compressor.

Title: Stabilising devices for vehicle suspension systems
IPC: B60G21/073
Filed: 1930-12-15
Abstract: 364,308. Preventing canting. DEUTSCH, F. A., 27, Rankestrasse, Berlin. Dec. 15, 1930, No. 37826. [Classes 103 (vi), 108 (ii), and 108 (iii).] In a vehicle stabilizer the action of which is practically eliminated when the suspension springs deflect equally in the same direction two cylinder casings 1 are arranged, one at either side of the vehicle, in which pistons 2 work under displacement of liquid dependent upon the relative movements between the wheel axle and the vehicle frame such that when the deflections are equal and of the same kind the quantity of fluid which is displaced in each casing can flow through cross connections 3 to the opposite side of the piston in the other casing such that the quantity of fluid displaced in one casing is equal to the space set free to take up liquid in the other casing. The stabilizer may be connected, or combined, as shown in Fig. 5, with a shockabsorber. In one form, the radial vane pistons 2, Fig. 1, coacting with fixed abutments are connected through systems of levers and rods to the wheel axle. Elastic elements, e.g. air, rubber or helical springs coacting with pistons 4, may be provided in the pipe lines 3. In order to prevent the stabilizer from functioning when say one wheel is raised by an obstruction a neutral zone may be provided by means of pistons acted upon by weak springs situated in bores in the wings or casings. In a modification of this arrangement, parts 4, Fig. 7, having non-return valves 5 are provided in each vane which coacts with a fixed abutment 2. Thus each vane acts in one direction for stabilizing and in the other for shock-absorbing and leakage of fluid is automatically made up. A throttle valve 7 may be fitted to each end of each pipe line 6 or may be fitted to one line only. Alternatively a beveledged piston acted upon by a spring of adjustable tension may be provided in one or both connecting pipes and may be arranged so that little or no resistance is offered to flow in one direction. In further modifications reciprocating pistons contained in two adjacent cylinders, or a single piston with two piston-rods may be used. The space in the casings not formed as a working chamber may be adapted for storing replenishing liquid. Two cylinder casings situated on the same side of the vehicle may be interconnected in order to equalize the load on the springs of the front and back wheels.

Title: Shifting mechanism for shifting a power-dividing transmission for motor vehicles
IPC: F16H48/30
Filed: 1977-09-13
Abstract: The control device serves for switching the front axle drive on in addition to the rear axle drive and at the same time for switching on a transmission stage of an auxiliary range transmission for road travel or for off-road travel. The device has two parallel selector plate slots each with a shift fork (2, 3). A common manual shift lever (1) serves for operation of the two shift forks (2, 3). The latter are coupled by a bridge (14), which has a longitudinal guide (13) for the shift finger (1a), so that they can swivel about parallel axes (4, 5). The bridge (14) is connected to the shift forks by way of a swivel pin (15) or by way of a pivot-slot coupling (17, 18). For a simple design construction, this allows the desired transmission stage and the desired axle drive to be selected as required. <IMAGE>

Abstract: 934,097. Feeding webs. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 17, 1959 [Nov. 27, 1958], No. 38236/58. Class 100 (1). [Also in Groups XXXIV, XXXV and XXXVIII] A web 2, particularly a magnetic tape, being unwound from a motor-driven spool 1, passes over a roller 3, is guided by rollers 6, 8 into contact with a capstan roller 7, and is thence passed over a roller 9 to be wound upon a second spool. Roller 3 is mounted upon a lever 4 pivoted at 5, increase in the web tension causing the lever to pivot against the action of retaining spring 15 thereby adjusting a potentiometer 13 to vary the voltage supplied to the motor driving the spool 1 to maintain the web tension substantially constant, as detailed in Specification 914,631, a dash-pot 14 controlling movement of the lever 4. Rotation of spool 1 may be stopped by a band brake 18 normally held on by spring 22 and moved to the off position by a solenoid 23 causing a bar 21 to be displaced against the action of spring 22. To avoid the web tension exceeding a predetermined value on braking the spool 1, levers 24, 25, pivoted respectively to the lever 4 and at a fixed point 26, are arranged so that an abutment 27 on the bar 21 is engaged by lever 25 through pivoting of lever 4 when the web tension reaches the predetermined value. Further increase in web tension causes lever 25 to move clockwise thereby displacing the bar 21 and reducing the braking force applied to the spool.
