Abstract: 719,826. Drying coal &c. LEHMANN & CO, AKT-GES.. H. May 22. 1952 [May 23. 1951]. No. 13029/52. Class 34(2) A method of dewatering fine coal &c. at rest in a tower or tank has three stages, water being removed first in continuous flow, then a stage in which the water separates dropwise and a final stage in which a dry gaseous, medium is passed through the material to evaporate moisture. The tower 1 has a perforated bottom funnel 2 surrounded by a metal screen 3 having means (not shown) for carrying away the water. The funnel 2 is closed by a slide 5 and a central perforated tube 6 acts as a passage for the drying air which may be drawn through by pressure or suction. In a modification, Fig. 5, having a closed outer shell containing a perforated screen 9, the gaseous medium is supplied through openings 10, 10<SP>1</SP> and passes over pipes 12 heated by waste heat. In other modifications the tower is divided into separate compartments each having a perforated tube.

Title: Improvements in or relating to automatic governors of infinitely variable-speed drives
IPC: F16H61/662
Filed: 1960-04-13
Abstract: 940,204. Variable-speed control. REGIE NATIONALE DES USINES RENAULT. April 13, 1960 [April 23, 1959], No. 13210/60. Headings F2C and F2D. In an automatic control for a continuous variable-speed gear in a vehicle, which gear may be mechanical, electrical, or hydraulic such as the fixed capacity pump/variable capacity motor 2, 5 shown, a spring-biased servomotor 11 indirectly or, as shown, directly actuating a ratio determining lever 7 controlling means such as a rheostat, valve, or pump capacity control is responsive to gaseous or liquid pressure regulated, from a higher feed pressure, through a pressure-reducing regulator 14 the thrust on a pressure-balancing spring 25 of which is varied by at least vehicle speed and engine load responsive means respectively acting to provide higher and lower gear as they increase. For engine braking, manual lever 45 and/or brake pedal 49 control may also vary the thrust of spring 25. The regulator 14 comprises a housing 17 having a bored piston 15 sliding in a cylinder fed by a pressure fluid through a port 18 and discharging through a port 19. The pressure source may comprise a compressor-fed air reservoir, which may also feed other vehicle systems (e.g. braking), the port 19 exhausting to atmosphere, or for the arrangement shown, a self-regulating pump with a pressure limiting device, the port 19 being connected to the pump suction. A regulated pressure chamber 22 connected to the servo through a line 12 is formed by the housing 17 and a diaphragm 20 connected to the piston 15 by a rod 23. The rod 23 may be fixed to the diaphragm or urged thereto by a spring 24 which, together with the arrangement of the ports 18, 19, serves to avoid periodic so-called " pumping " in the regulator. The spring 25 acts between the diaphragm 20 and a disc 26 pivoted to the lever 27 fulcrumed at 28. To keep engine speed constant for each fraction of engine load the vehicle speed responsive means provides a thrust substantially proportional to speed and may comprise a Watt or pendulum type centrifugal governor, or other mechanical, hydraulic or electromagnetic device, or, as shown, centrifugal balls 42 between an axially fixed concave plate 40 rotated by the output shaft 6 of the variable speed gear through a belt 36 and a rotationally fixed but axially slidable concave plate 41 the shaft 43 of which is pivoted to the extremity of the lever 27. The engine load responsive means may comprise a spring interposed between the lever 27 and linkage connected to the throttle control or, as shown, a piston or diaphragm 29 linked to the lever 27 and subjected through a line 31 to inlet manifold depression at 32. A spring 33 may load the diaphragm 29. To obtain lower gear for engine braking the lever 27 may be connected to a manual lever 45 through a spring 46, and/or the usual brake pedal 49 through a spring 52. An indicating sector 48 provided for the lever 45 has positions " N " (normal operation) wherein the spring 46 is unstressed, and " F " (maximum braking force).

Class 38 (4) An electromagnetic relay 14 for starting one or a plurality of series connected discharge tubes such as fluorescent lamps 1, 2, has respective normally open contacts 12, 13 for completing a heating circuit for the filamentary electrodes 8, 9 ; 10, 11 of the tubes and a normally closed contact 16 in the main current supply circuit of the relay coil 15, which coil is shunted by a capacitor 17 and is parallel connected with the series arrangement of the tubes 1, 2 and their ballast impedance 3. On application of the supply, capacitor 17 is charged and coil 15 is energized to close the electrode heating circuit and to open its own supply circuit, but is held energized for a predetermined heating period by the charge on capacitor 17 ; when the relay releases the resultant surge initiates the tube discharges. Discharge current volt drop in a resistor 6 reduces the voltage across the coil 15 to below its " pull-in " value. The arrangement is for D.C. working, but for A.C. operation a rectifier 21 is connected in the relay coil circuit. The ballast impedance 3 may be a resistor or a choke. An indicating or alarm device, such as a neon lamp 20, may be connected across the coil 15 to draw attention to protracted starting operations. For D.C. operation supply current reversing means may be provided.
