Title: Shaking-funnel apparatus for the gravity concentration of solid particles
IPC: B07B13/08
Filed: 1965-01-21
Abstract: 1,087,113. Separation of solids. A. MOTOSI. Jan. 21, 1965 [Jan. 21, 1964], No. 2656/65. Heading B2H. An apparatus for the gravity separation heavy and light materials of practically the same size comprises a container 1 having a wide-angled, funnel-shaped bottom or diaphragm 2 provided with an outlet port 10 at its lower part, an outlet duct 14 opening in the container a certain distance above the port 10, means for mounting the container, means for imparting a combined gyratory and vibratory movement to the container and a pipe 15 and a conical baffle 16 for feeding the mixture of materials, either in the dry state or in water, to the periphery of the container. Due to the conicity of the bottom or diaphragm 10 and to the gyratory and vibratory movement of the container, the materials to be separated tend to flow or settle with different settling speeds along spiral paths towards the outlet port 10 but due to the difference in settling speeds, they separate into a lower layer of heavy material which is removed through the port 10 and a channel 13 and into an upper layer of light material which is removed through the duct 14 by means of a pump P. A valve 11 on an adjustable lever 12 controls the discharge through the port 10. The container is supported on a member 3 mounted on the pins 4 of three cranks 5 mounted on a framework 6 and driven by a motor 8 through a belt 9 and gears 7. The construction of the cranks, the gears and the framework is sufficiently rough and have such a play as to vibrate the container when the latter is driven. The throw of the cranks may be adjustable. In a modification, the pipe 14 may be introduced from below through a wider central port 10. In another modification, the pipe 14 is introduced centrally from below but the discharge for the heavy material is through a number of openings provided in the bottom 2 around the pipe 14. In a further modification, the pipe 14 penetrates through the side wall of the vat as shown in dotted lines and may be slightly inclined or horizontal and may be provided with a downwardly bent end opening above the port 10. In another embodiment, Fig. 8, the container 1 is divided internally by a number of funnel-shaped diaphragms 2 vertically spaced above a bottom 2, each diaphragm and the bottom having a central discharge port 10. A discharge duct 14 opens above each port and a conical baffle 16 is provided above each diaphragm and the container bottom. In a further embodiment. Fig. 9 (not shown), the container is suspended from a support and the driving cranks may be slightly inclined to increase the vibrations imparted to the container.

[Class 29] Absorption machines.- In an air-cooled reversing system employing a solid absorbent, the change in volume of a congealable liquid acts on means tc stop the cooling of the generator-absorber when the evaporator temperature is low and the pressure of a liquid heated simultaneously with the generator acts on th( same means to stop the air cooling during the generating period. A damper 5 at the top of a cooling-air shaft 2 of the generator-absorber 1 is actuated through a pinion and rack by a bellows 11 connected through pipes 12 with thermal elements 13, 14 influenced respectively by the temperature of the evaporator brine tank 19 and that of the generator-absorber, so that it is closed to stop absorption and evaporation when a low temperature is reached by the evaporator and also during the generating period. The temperature sensitive medium is preferably a mixture of water or alcohol and glycerine adapted to expand in the element 13 on freezing. The heating of the generatorabsorber is preferably controlled by other thermostatic means in accordance with the temperature of the generator.

Abstract: 1,074,722. Radio signalling. MOTOROLA, Inc. Jan. 20, 1966 [Feb. 15, 1965], No. 2686/ 66. Heading H4L. In a frequency-diversity microwave transmission system in which a pair of carrier waves are modulated by a common signal and radiated by a common radiation device, means being provided at the receiver for demodulating each carrier wave separately and continuously selecting the stronger of the two demodulated signals, the frequencies of the carrier waves are arranged to be in the ratio of two immediately successive integers.

Abstract: 491,424. Ice - making; sheet - metal joints. GENERAL MOTORS CORPORATION. Jan. 28, 1938, No. 2744. Convention date, Feb. 10, 1937. [Class 29] [Also in Group XXII] A sheet-metal grid for ice-making trays comprises a longitudinal wall 11 and a series of transverse walls 12 separately movable to a limited extent in relation to the longitudinal wall so that one or more pairs of ice cubes may be detached by application of pressure by the finger or otherwise to tabs 18 on the upper edges of the transverse walls. The longitudinal wall may be fitted with a ring handle 13. The transverse walls are formed with slots 15 deeper than the longitudinal wall and are threaded thereon in succession to engage notches 16, 17 in the bottom and top edges of the longitudinal wall, and are then locked in the notches by bending over tongues 19<1> of the tabs 18. The upper notches are wider than the lower and enable the transverse walls to settle to parallel inclined positions when the grid is placed haphazard in the tray and shaken into place. Means such as that described in Specification 489,247 including a longitudinal actuating bar or link above the longitudinal wall, may be employed for moving the transverse walls. The surfaces in contact with the water may be coated with hard wax to facilitate release of the ice.

Abstract: 1,181,303. Coated articles. MINNESOTA MINING & MFG. CO. 18 Jan., 1967 [18 Jan., 1966], No. 2744/67. Heading B2K. Mineral granules, sheet aluminium, steel, ceramic bodies, asbestos cement articles are coated with an aqueous, pigmented alkali silicate colour-coating composition, and the coating is insolubilized by firing the coated granules to cause the alkali silicate to coreact with at least two reactants selected from the group: (a) oxygen containing boron compound contained in the colour-coating composition, (b) cryolite contained in the colourcoating composition and (c) calcium carbonate contained in a pre-coating forming the substrate for the colour coating composition, the pre-coating having been insolubilised by a previous firing. In an embodiment mineral granules are coated with an aqueous coating composition comprising an alkali silicate, a pigment, heat reactive clay and calcium carbonate. The pre-coated granules are fired to at least 850F., and an outer aqueous colour coating composition is then applied, comprising the oxygen containing boron compound and the cryolite reactant. The coated granules are then fired at a temperature of at least 500F. The granules may be coated by tumbling with the coating compositions in a barreltype mixer. In the examples granules such as syenite, diabase greystone are coated. Composite sheet bodies for roofing and siding comprise a bituminous sheet material having a firmly adherent surfacing consisting essentially of the colour coated granules.
