Filed: 1936-05-05
Abstract: 473,370. Valve relay circuits. CAPASWITCH, Ltd., and LANCASTER, C. G. May 5, 1936, No. 12731. [Class 40 (v)] In apparatus wherein the approach of a person or moving object effects a change in the electric capacity of parts associated with an oscillatory circuit whereby a relay is actuated to operate a switch or alarm device, there are provided devices responsive to changes of temperature or pressure occurring in the neighbourhood of the apparatus and compensating for variations in the controlling capacity due to these factors. An aerial 1 is connected through a tuning inductance 2 to the grid of a thermionic valve 3, the anode of which is connected to an inductance 4 having a variable coupling with the aerial coil. The anode circuit includes a coil 8 for actuating a relay 9 to complete an alarm circuit or the lighting circuit of, say, a shop window. The oscillatory circuit is tuned so that the valve oscillates vigorously when a person approaches the aerial 1. Connected in the aerial circuit at either of the positions a, b is a temperaturecompensating device comprising a mercury thermometer 12, the mercury of which is connected to the aerial; alternatively metal foil is wrapped round the thermometer bulb and the aerial is attached to or wound around this foil. In a modification, Fig. 3, an earthed piece of metal 13 is arranged near the thermometer stem and inclined to it, thus introducing a small variable capacity. In place of these devices, a variable condenser controlled by one or more bi-metallic strips may be connected at positions a, b or 14. Two such variable condensers 15, 16, Fig. 5, may be connected respectively in parallel with the anode tuning coil 4 and the aerial tuning coil 2. These condensers have each one plate fixed to a panel 19, the other plate being carried on the bi-metallic strip 17, 18 made of brass and steel, brass being outermost in one strip, and steel outermost in the other. Set screws 21 adjust the initial setting of the strips. Changes of atmospheric pressure are dealt with by transmitting through levers the movements of an aneroid drum to one or more elements of the controlling capacity.

A slurry is filtered on a filter layer of particles 9, Fig. 2, which are coarse relative to the comparatively fine particles of solid in the slurry whereby some of the comparatively fine particles penetrate the filter layer to some extent, and the remainder of the comparatively fine particles form a layer 15 above the filter layer, the two layers being of such composition that they may be used together for an industrial process. The filter layer of coarse particles may be formed on another layer of similar particles 8, by filtration, and after formation of layer 15, the two layers 9 and 15 may be removed by blade 18, and further layers 9 and 15 formed. In Fig. 1 and 2, an aqueous suspension of coarse grains comprising one or more of iron ore, blast furnace dust coke dust or crushed limestone is fed by pipe 7 onto the whole of anti clockwise rotating filter table 1 to form foundation layer 8. A second layer 9 of the coarse grains is then formed by filtration of further suspension from pipe 7 and levelled by blade 11. A slurry of fine iron oxide particles is then continuously fed from pipe 13 and is filtered in a zone bounded downstream by a levelling blade 14. Some of the particles of iron oxide penetrate layer 9, and the rest form a layer 15. Supernatent water may be removed by sucking tube 16, and the layers are dried beyond blade 14. After drying, layers 9 and 15 are extracted by blade 18 as table 1 rotates and are then removed by a lateral transporter comprising scraping arms 22 mounted on chain 21 to mixer 23. Blade 18 and apron 19 are pivotable about axle 24 so that layer 8 can also be extracted by blade 18. Filter table 1 comprises a filter cloth 3 supported by perforated sheets 2 of metal. The process of the invention may be used for recovering clay using crushed limestone, fine coal using coarse coal, and schist using coarser schist.

A gyratory crusher, comprising a longitudinally-extending shaft 25 carrying a mantle 28 loosely encircled by a fixed crushing ring 15, includes a head 30 on the shaft at or towards its upper end, a hydraulically-suspended bearing 23 supporting the shaft through the head and permitting the axis of the shaft to gyrate and the shaft to yield in the event of excess pressure between the mantle and the crushing ring. The lower end of the shaft is constrained to move around a circle, and the shaft and mantle return to their normal working position after relief of the excess pressure, this position being determined by a fixed, non-adjustable abutment 36 against which a part, viz. the upper end of an annular piston 19 carrying the bearing, is yieldingly pressed by the hydraulic suspension so as to locate the mantle with respect to the crushing ring in an operative position, and the head is adjustable on the shaft to adjust the mantle towards and away from the crushing ring so that the operative position of the mantle with respect to the crushing ring is varied. The outer race 22 of the bearing is housed in the piston 19, movable in a cylinder 17 and normally maintained against the abutment 36 by hydraulic pressurefluid admitted through a passage 18. The screw-threaded upper end of the shaft 29 engages the threaded head 30 whose lower surface 31 engages the upper face 32 of a ring 33 supported on the outer race 22 by a distance piece 34, so that adjustment of the head locates the shaft and mantle in relation to the crushing ring. When uncrushable material becomes lodged between the mantle and the crushing ring, downward thrust is applied to the shaft, which is transmitted through the head 30 to the bearing and piston 19 and the liquid beneath the piston is forced out through the passage 18. Gyratory movement is applied to the lower end 35 of the shaft 25 by eccentric mechanism as described in Specification 973,045.
