Title: Positive evacuation of fccu reactor dilute phase volume
Inventor: STEFFENS TODD R
IPC: B04C5/12
Filed: 1993-11-01
Abstract: In its simplest sense, the present invention provides a uniquely shaped conduit between the primary and secondary cyclones or, in the alternative, between the riser and the primary cyclone, which creates an increase in the auction of the dilute phase vapor beyond that normally available in the reactor vessel, thereby reducing the dilute phase residence time in the vessel, reducing post-riser thermal cracking, hydrogen transfer reactions, and coking tendency of mixture in dilute phase.

Abstract: POWER TRANSMISSION            ABSTRACT OF THE DISCLOSURE          A countershaft transmission has an input shaft and a coaxial output shaft which are disposed in parallel with a pair of countershafts.  The countershafts position and support a floating bearing support which is positioned to support ends of the input and output shafts.  The countershafts each have a selectively engageable clutch disposed thereon which selectively control the establishment of drive ratios between the input shaft and the respective countershafts.  A plurality of forward and reverse ratios are selectively established, between the input and output shafts through the countershafts, by selectively engaging a plurality of synchronizers. The synchronizers cooperate with a plurality of ratio gears on the countershafts and output shaft to establish the ratios.  The ratio gears that establish the lowest forward ratios are fully disengageable from their respective countershafts.

Title: Waste-water treatment system
Inventor: HAWES PHILIP B
IPC: C02F3/30
Filed: 1992-09-18
Abstract: The present invention discloses a portable waste-treatment system. The waste-treatment system comprises anaerobic holding tanks for the anaerobic digestion of waste, and aerobic marches (20, 34 and 42) for the aerobic digestion of waste. The waste-treatment system has a relatively small volume of about 1,000 to 2,000 liters for each person using the marsh. Aerobic digestion in the marshes is promoted by aquatic and marsh plants and the microorganisms associated with such plants, which are grown in the marshes. The marsh plants are grown in soil and gravel layers (30 and 46) in the marsh. The soil and gravel is layered on the floor of the marsh around baffles (26, 28, 38, 39, 48 and 50) in a pattern that forms an open water channel (36 and 44). Aquatic plants are planted in the open water channel. The presence of the baffles results in the waste being directed along a sinuous path through the marshes. Means for recycling treated water back to the holding tanks or the marshes is also provided, if further treatment of the waste is desired.

Title: Handwritten symbol recognizer
Inventor: DAI XIWEI
IPC: G06F3/0488
Filed: 1994-06-07
Abstract: HANDWRITTEN SYMBOL RECOGNIZER         Abstract of the Disclosure A handwritten symbol recognizer adapted to automatically recognize various handwritten symbols including Kanji character is disclosed. The symbol recognizer includes a data processor coupled to a user interface that receives handwritten input symbols from a user and displays reference symbols determined by the symbol recognizer to correspond to the handwritten symbols. The data processor includes a memory unit which temporarily stores coordinate information representing features of the input symbols as received from the user interface. The data processor includes a symbol analyzer that retrieves the coordinate information from the memory unit and translates the coordinate information for each written feature into a feature code representing one of a predetermined number of feature models stored in the memory. The symbol analyzer also creates a geometric representation of the input symbol for comparison with one or more geometric models stored in the memory unit. The data processor also includes a label comparator adapted to compare the feature codes for the input symbol with feature codes of reference symbols stored in the memory unit and to identify the reference symbol or symbols having feature codes that most closely match the feature codes of the input symbol. The data processor also includes a geometric comparator that compares stored geometric models corresponding to the reference symbols most closely matching the input label with the geometric representation of the input symbol. The geometric comparator uses its comparison to identify the reference symbols whose geometric model or models most closely match the geometric representation of the input symbol. The reference symbol that most closely matches the handwritten input symbol, as determined by the label and geometric comparators, is sent to the user interface which displays the reference symbol to the user.

Filed: 1994-09-15
Abstract: A variable capacity vane compressor has an axial pressure device for applying variable axial pressure to a rotary valve.  The rotary valve plate locates in a rotary valve housing and changes the capacity of the compressor due to its rotary position.   An actuator member rotates the rotary valve plate in response to varying pressure in the discharge and intake chambers. A control valve supplies a variable control pressure to the actuating member for moving the actuating member to rotate the rotary valve plate.  An annular axial pressure chamber is located between the rotary valve housing and the rotary valve plate.  A control pressure port leads from the control valve to the axial pressure chamber.  A seal member within the axial pressure chamber applies an axial force on a bearing located on the rotary valve plate.    The  control  valve  which  supplies  variable pressure used to vary the actuator member position also supplies the control pressure to the axial pressure chamber.
