Patent CA-1098026-A (CA)
Inventor: HORAN RALPH P
IPC: B01D3/10
Filed: 1978-09-13
Granted: 1981-03-24
Abstract: APPLICATION OF:  RALPH P. HORAN            FOR:  VAPOR COMPRESSION LIQUID TREATING SYSTEM            A B S T R A C T        A liquid containing a solvent to be evaporated is fed to a concentration chamber which is fluidly connected to an evaporation chamber maintained at a reduced pressure.  A vapor compression means withdraws solvent vapor from the evaporation chamber, compresses the vapor and forces the compressed vapor to a liquification chamber.  Regulator means responsive to the density of the liquid remaining within the concentration chamber will regulate the rate of solvent evaporation to provide a concentrate suitable for recycling.      In one form of the invention, a variable capacity heat exchanger can be used to control the rate of solvent removal The heat exchanger has a liquification chamber to receive com-pressed vapor which surrounds an evaporation surface in fluid communication with the concentration chamber.  A portion of the liquification chamber is filled with liquid. The amount of evaporation surface being contacted by liquid or vapor can be varied thereby varying the amount of heat which is transferred from the compressing vapor to the solvent to be evaporated.  Since the vapor and liquid normally have different rates of heat transfer, the amount of heat given to the evaporation surface also varies.

Abstract: ABSTRACT OF THE DISCLOSURE         A top operated tank car valve assembly includes a rod extending downwardly from the top of the tank and is attach-ed to the valve stem of a lading valve located in the bottom of the tank.  The stem engages a threaded valve sleeve provided with a mounting flange which engages a cooperating mounting flange on a valve cage.  Fasteners engage the upper surface of the sleeve, and extend through the valve cage and engage thread-ed openings in a tank car bottom outlet mounting flange.  The cage includes a valve seat for a valve closure.  The valve seat is formed on the lower, internal surface of the valve cage, and circumferentially spaced openings are formed in the valve cage for lading flow.  Laterally spaced projections extend up-wardly from the lading valve closure.  A valve stem retainer includes a pair of formed retainer members which define a cavity or opening.   The retainer engages the lower end of the valve stem with a sufficiently tight fit as to substantially reduce horizontal and angular movement of the stem relative to the stem retainer.  Slots formed in the retainer receive the projections from the lading valve closure and fasteners hold the formed retainer members in abutting relation to the closure projections.  A valve guide depends from the valve clo-sure a sufficiently short distance as to not extend below the tank mounting flange, and thereby a skid is not required in order to comply with AAR and DOT regulations concerning projec-tions extending below the bottom surface of a railway tank car.

Abstract: Disclosed is a satellite controlled clock operative to receive time code, a standard pulse set and satellite position modulated radio frequency carries waves from either of two geostationary satellites operating at different carrier wave frequencies.  The clock has a radio receiving stage and a switch for selecting the carrier frequency of either of the satellites.  A frequency scanner incrementally sweeps the receiving stage through a frequency band including the selected satellite carrier frequency responsive to the application of power to the receiver and selection of a satellite by the switch.  A phase locked loop tracks the selected satellite carrier wave and the frequency scanner is disabled upon detection of the satellite carrier.  Disablement of the frequency scanner causes a local clock to be synchronized with pulses from the satellite.  A decoder decodes a time code transmitted by the satellite.  A coding switch enables introduction of the receiver's position into the receiver in code form.  A calculator calculates the path time delay of satellite signals from the known satellite position and the receiver's position.  Decoded time signals from the satellite are combined with the path time delay calculations and the corrected time displayed.

Abstract: INNER LOCKING CYLINDER WITH CAPTIVE KEY     ABSTRACT          A dead bolt lock set is designed to be key actuated on the inside as well as on the outside of the door   For the inside there is an inside tailpiece in engagement with a drive slot in the dead bolt hub.  A lost motion circumferential recess on the inside tailpiece provides stops at positions such that when the key is inserted on the inside and turned to lock the dead bolt by action of a micro drive pin, the key cannot be returned in reverse direction to key release position without unlocking the dead bolt.  Consequently, the key must remain captive in the inside keyway to keep the dead bolt locked because of being held in the cylinder by the pin tumblers.     When the lock has been locked from the outside, the drive slot in the head of the tailpiece is rotated out of line with the inside key slot.  Under this condition when unlocking from the inner trim, the tailpiece and washer are forced inward by the key tip compressing the conical spring and allowing full key insertion.  Bolt retraction (unlocking) may be accomplished by rotation of the key in the bolt extended direction until the key tip aligns with the tailpiece drive slot, then rotating the key back to the vertical (withdrawn) position, or, in the alternative, rotating the key in the retract direction, whereby the micro pin contacts the lost motion stop on the tailpiece head thereby driving the mechanism to the retracted position.  The captive key mechanism is fail safe in that in the event the conical spring fails to return the tailpiece to a position abutting the end of cylinder plug for captive key operation, the mechanism will still function as a standard cylinder allowing normal locking and unlocking.
