Title: Improvements in washing apparatus for coal or the like
IPC: B03B5/24
Filed: 1930-05-09
Abstract: 352,152. Washing granular materials. WITZAL, A., 1304, St. Ann Street, Scranton, RABEL, A. G., 701, Dunmore Street, Throop, and STEVENS, H. F., 319, North Blakely Street, Dunmore, all in Pennsylvania, U.S.A. May 9, 1930, No. 14336. [Class 82 (ii).] Coal or like material is separated from refuse in a separating tank by the action of a stream of water, the refuse passing through a discharge opening on to a hinged plate, the inclination of which is controlled by the variations in the water level in a compartment communicating with the separating compartment through the refuse discharge opening, the variations in the water level being produced by changes in the quantity of refuse in the separating compartment. The coal &c. is fed beneath an adjustable baffle 15 on to a screen 10 in a separating compartment 2 to the bottom of which a steady stream of water is supplied through a pipe 3. The coal is raised by the water and passes over a transverse baffle 16 on to a platform 17 of inverted V-section which discharges it to perforated troughs 20, 21 with adjustable gates, the water associated therewith draining on to a cover 24 and passing to a tank 5 connected through a pump to the pipe 3. The refuse passes through a discharge opening 29, formed by an adjustable gate 30 with flange 85, on to a plate 35, with sides 37, hinged to the end of the screen 10. The opening 29 connects the compartment 2 with a compartment 25 in which the water is comparatively quiescent, the level of water therein rising as the quantity of refuse on the screen 10, and consequently the resistance to the flow of water in the compartment 2, increases. A float in the compartment 25 controls the inclination of the hinged plate 35. In the form shown in Fig. 1 a float 55 is adjustably mounted on a rod 50 passing through a ring 51 and carrying stops 60, 61, the lower end of the rod being connected to the plate 35 by a curved lever 45, pivoted at 46, a link 47 and projection 48. In the modification shown in Fig. 4 a float 70 is carried by a rod 68 connected to one end of a lever 65 pivoted at 66, the other end of the lever being connected to an extension 63 on the hinged plate 35 by a rod 62 adjustable in length passing through a tubular member 71 formed in the platform 17. Counterweights 72 may be provided on the float. As the quantity of refuse in the compartment 2 decreases, the level of water in the compartment 25 falls, the float sinks, and the hinged plate 35 is raised into a horizontal position, stopping the discharge of refuse. The height of the water in the compartment 2 is limited by an opening 24a controlled by a gate 24b.

Title: An aeroplane suitable as a toy or for sport
IPC: A63H27/00
Filed: 1921-05-24
Abstract: 186,374. Shreiber, N. May 24, 1921. Toy gliders and flying- machines. - A toy a,eroplane has planes which may be folded against its body so that it can be thrown or shot like an arrow, the folded planes being automatically unfolded when it has attained a certain height. A propeller c is driven by a twisted rubber band e, which is held in its twisted state. by a sleeve d having a finger d<1>, which engages a bracket on the end of the supporting-tube a but is slid back out of engagement when the aeroplane is thrown. The planes f are of flexible material fixed to rods f<1>, f<2>. They may be folded by turning the rods f<1> about their pivots f<3> and rolling the fabric on the rods f'. Triangular tail planes g are fixed to rods g<1>, pivoted at g<2>, and the planes are kept extended by elastic cords i, g<3>, and a spring g<4>. The planes are held folded by cords l<1>, l<2>, the loops of which are received bv the ends of wire hoops m, m<1> which are pulled through wire sleeves l by a lever o against an elastic cord p. The lever o is held down by a finger n<3>, which is retained in an horizontal position by the action of the twisted rubber band e, but is turned to a vertical position, to release the lever o, by a helical spring n<2> when the torsion of the rubber band e has been reduced. A folding chassis h is extended simultaneously with the wings by an elastic cord h<1> and wires h<2> fixed to the ends of the rods g<1>. A launching-device may comprise a sleeve, having a socket for the folded aeroplane, which is slid down a rod against the pressure of two helical springs and let go when the rod points in the requisite direction, a third spring being provided as a buffer. The aeroplane may also be launched from a stick, the end of which is inserted in a loop in the propeller spindle which replaces the sleeve d. Alternativemethods of fixing the loops of the cords l<1>, l<2> consist in replacing the finger n<3> by a wire having kinks or a rod having fingers which directly hold the cords l<1>, l<2> until the torsion from the rubber band e has been reduced. A modified release for the lever o comprises a hook which is carried by a nut screwed on the propeller spindle; in this case the propeller is not actively driven, but is freely rotated by its passage through the air and thus, after a definite number of revolutions, the nut is traversed a sufficient distance forwards to release the lever o. The rods f<2> may be omitted, and short rods, hinged to the mid-points of the rods f<1>, may be connected to the opposite corners of the planes by springs. A stiff adjustable tail plane may be carried by the end of the rod a.

Abstract: 311,381. I. G. Farbenindustrie Akt.- Ges. May 10, 1928, [Convention date]. Addtion to 304,207. Void [Published under Sect. 91 of the Acts]. Caoutchouc, synthetic.- In the production of synthetic rubber, wherein an artificial latex is produced and is coagulated by cooling below 0‹ C. as described in the parent Specification, the separation of the emulsifying agent is facilitated by removing the unchanged diolefine before or after the cooling but before the washing of the coagulum. The removal of the diolefine is effected by evaporation, for instance by passing indifferent gases through the latex or by rolling the coagulated product, and simple heating or reduced pressure may be employed. In the examples, latex obtained from an emulsion of isoprene with sodium oleate or sodium desoxycholate solution is coagulated by cooling to -20‹ C., and the unchanged isoprene is driven off by (1) rolling with gentle heat; (2) heating; (3) treatment with steam. In each case the emulsifying agent is then removed by washing.
