Title: Vortical cyclone cluster apparatus
Inventor: RASTATTER EDWARD L
IPC: B04C5/28

Granted: 1980-07-15
Abstract: Abstract of the Disclosure A cluster of closely spaced cyclones are arranged with their axis in parallel spaced relation, and cylindrical portions of the cyclones form rigid connections between parallel walls which define a chamber for directing fluid into corresponding tangential inlets within the cyclones.  In one embodiment, the walls are formed by flanges molded as integral parts of the plastic cyclone bodies, and the flanges are interconnected by key members.  In another embodiment, the walls are formed by flat plates which are rigidly connected by independently removable molded plastic bodies having integral threads.  Each of the cyclones includes a replaceable apex cone section which may be ceramic and has an externally threaded portion projecting into an apex discharge chamber defined between an inner wall and a parallel spaced transparent outer wall.  Each apex cone section is secured to the inner wall by a nut member, and the transparent outer wall is provided with an axially aligned opening and valve for each cyclone for introducing a back flushing fluid or to produce a vacuum at the apex end.  The apex cone sections may be secured to the apex discharge housing by threaded sleeves which also form spacers between the walls of the housing and which support corresponding transparent rings.  A ceramic probe is adjustable axially within each ring and has a conical inner end which cooperates with the apex end of the corresponding cyclone to define an adjustable annular discharge orifice.  The opposite ends of the cyclones have molded plastic closures with vortex finders which project into a vortex chamber defined by a removable cover member.  The vortex finders may also project into a tank connected to a vacuum source for deaerating liquid which is received within the tank.

Abstract: ABSTRACT OF THE DISCLOSURE         A speed-responsive electrical switch assembly consisting of a centrifugally-actuated switch operating unit customarily mounted on a rotat-able shaft and having orbitally movable weights engageable with the surface presented by a switch unit to cause make and break operation of the electrical switch contacts.  The radial centrifugally-induced inboard and outboard movement of the weights themselves in engagement with the surface of the switch unit, preferably an angularly inclined cam surface, serves to modulate the axial or longitudinal switch-operating, spring-induced displacement of the weights toward or away from the electrical switch unit and thus permits greater latitude in manufacturing and assembly tolerances and with improved switch operating characteristics while still maintaining prior art standards of precision switch control and uniformity of switch action.

Abstract: IMPROVEMENTS RELATING TO THE BURNING OF PULVEROUS OR GRANULAR RAW MATERIALS            ABSTRACT OF THE DISCLOSURE         A method is disclosed for burning pulverous or granular raw material such as cement raw meal in a rotary kiln plant by directing a first flow of raw material to a cyclone preheater, preheating the first flow of raw material in the cyclone preheater, and directing the preheated raw material from the cyclone preheater to a rotary kiln for burning the material in the kiln.  The burnt kiln product is directed to a cooler which may be of several types and which communicates with the material outlet of the kiln while a second flow of fresh raw material is directed to the cooler to at least partially cool the burnt kiln product by trans-ferring heat therefrom to the second flow of fresh raw mate-rial in the cooler.  The method further involves combining-the preheated, at least partially calcined second flow of material with the first flow of preheated, at least partially calcined material prior to directing the combined flows to the rotary kiln and thereafter directing the combined flows to the kiln for burning and for subsequent cooling in the cooler.  The invention also pertains to a unique kiln plant for practicing the inventive method.

Abstract: COLOR TELEVISION CONTROL CIRCUIT FOR USE WITH A VIR SIGNAL         ABSTRACT OF THE DISCLOSURE     Color television receiving apparatus for receiving and demodulating a composite color television signal including horizontal synchronizing signals, color burst signals, and lumi-nance and chrominance components.  This composite color television signal is of the type which additionally may or may not include a VIR signal which, typically, is broadcasted in a predetermined line interval during the vertical retrace period of the composite color video signal.  The apparatus includes the demodulator for demodulating the chrominance component, which has been separated from the composite video signal, into its color signal components.          A signal generator generates a signal, such as a gate signal, during the predetermined line interval in which the VIR signal is expected.  Control circuitry is energized by this generated signal to respond to selected components produced by the demodu-lator during the line interval in which the VIR signal is provided for producing signals which are used to control the color signal components demodulated by the demodulator, such as to control the hue and saturation of such demodulated components.  Manually oper-able adjusting circuitry is coupled to the control circuitry for selectively varying the control signals in accordance with an oper-ator's particular preference for hue and/or saturation characteris-tics of the reproduced color video picture.  In one embodiment, switching circuitry is provided to selectively energize the control circuitry either with the aforementioned generated gate signal or, in the event that the transmitted video signal is not provided with a VIR signal, with an alternative periodic gating signal, such as a signal derived from the horizontal sync signal.                             -i-

Abstract: 3.3.76 ABSTRACT:         An apparatus is described for reading a record carrier, on which information, for example video and/or audio information, is stored in an optically readable track-shaped information structure.  Errors in the focus-sing of a read beam relative to the plane of the infor-mation structure can be detected with the aid of two detectors which are disposed in the far field of the information structure, which detectors are arranged at one side of a plane defined by the optical axis of an objective system and a line which effectively extends transversely to the track direction and which longitudinal direction are effectively transverse to the track direction.  With the aid of the same detec-tors a reference signal is obtained, which is employed for deriving a control signal for focussing correction of the read beam.
