Title: Sanitary waste disposal system
Inventor: ZACCAI GIANFRANCO
IPC: E03D5/00
Filed: 1993-03-03
Abstract: ABSTRACT A sanitary waste disposal system is used with a water supply and a sewer line. The system includes a toilet bowl having an inlet opening for receiving water from a water supply and a discharge opening for draining water from the toilet bowl. A wasteline is in fluid flow communication with the toilet bowl discharge opening and the sewer line. In one aspect of the invention, at least a portion of the wasteline is moveable between a raised trap-forming position and a lowered drain position. Inthe raised trap-forming position, an underside of said portion is higher than the discharge opening to maintain a desired level of water in the toilet bowl and block odors from the sewer line. In the lowered drain position, the underside of said portion is at least lower than said level of water in the toilet bowl to create a pressure differential which induces flow to the sewer line. To flush waste and water from the toilet bowl, the wasteline is moved from the raised to the lowered position. In another aspect of the invention, an outer frame is adapted to be positioned inside a recess in a wall, and a carrier frame is positioned within the outer frame and is vertically moveable and guided within said outer frame. The toilet bowl is connected to the carrier frame and moves therewith to a desired vertical position. A water supply is adapted to accommodate for changes in the height of the toilet bowl, and the wasteline is moveable to accommodate for changes in the height of the toilet bowl. In yet another aspect of the invention, a cabinet is positioned substantially above and behind the toilet bowl. The cabinet has side walls and aback wall which define an interior chamber, and wash means which extend into the cabinet chamber. The toilet bowl is rotatable from a substantially horizontal lowered position to a raised position in which at least a portion of the bowl isinside the interior chamber of the cabinet. In addition, a retractable cover conceals the interior chamber of the cabinet when the toilet bowl is in the lowered position, and the wasteline is moveable to accommodate for the rotation of the toilet bowl between the lowered and raised positions. In yet a further aspect of the invention, a pair of spaced apart, rotatable armrests are positioned above the toilet bowl when the bowl is in the lowered position and are pivotable about a horizontal axis. The armrests cooperate with the toilet bowl such that they rotate upward when the toilet bowl is raised.

Title: Towable road tender
Inventor: BARTO ROLLIN V
IPC: E02F3/76
Filed: 1993-05-21
Abstract: ABSTRACT OF THE INVENTION     A towable road tender device for grading unpaved roadway surfaces. The tender device may be hitched to commercial vehicles but is particularly suited for use with private vehicles, such as small tractors and pickup trucks. A set of relatively lightweight frames reduce the weight to be pulled by the vehicle. The towable road tender device is sized to be operated using small-scale power take-off units commonly available in private vehicles, such as, for example, the power units of conventional front-end plows. The set of lightweight frames includes a support frame that secures the tending tool, a wheel frame that pivots the rear towing wheels either toward or away from the support frame, and an attachment frame joining the other two frames to a hitch on the towing vehicle. The attachment frame is designed to keep the support frame parallel to the plane of the underlying roadway surface as that support frame is raised or lowered. The height differential between the hitch of the towing vehicle and the support frame normally results in a lifting of the front of the support frame and a reduction in the bearing weight of the tending tool on the roadway surface. The attachment frame of the present invention eliminates this problem by pivoting upward when the tending tool is lowered down to the roadway surface. This pivoting not only eliminates the lifting, it enhances the bearing capacity of that tool.

Patent CA-2104355-A1 (CA)
Inventor: INCULET ION I
IPC: C02F1/78
Filed: 1993-08-18
Abstract: A water treatment apparatus is provided in which the ozone generation and the water treatment may take place simultaneously.  The ozone is generated from a continuous supply of air and/or oxygen at the surface of a running water by means of a high voltage electrode placed in the air or in oxygen at some distance above the water surface.  The strong electric field between the high voltage electrode and the surface of the electrically grounded water stream generates a multitude of small Taylor cones at the surface of the water.  Each Taylor cone goes into corona and in the process it generates the ozone.  As the ozone is generated at the water surface, a substantial amount of ozone is immediately dissolved in water and the ozone that diffuses in the air continues to be in contact with the water surface.  The undissolved ozone may be percolated through the same water for an additional primary or secondary ozonation.

Title: Method and apparatus for controlling a press
Inventor: O'BRIEN MICHAEL J
IPC: B30B15/00
Filed: 1993-01-07
Abstract: A process controller (14) disposed to monitor and control a press (12). The controller (14) monitors an appropriate variable at the press (12) representative of the force produced at the workpiece (40) upon which the press (12) is operating, and compares this force to historical force data associated with the position at which the force was sampled. The historical data is stored in the form of control arrays, where the control arrays are calculated based upon one or more signature arrays stored during satisfactory press (12) operations upon a similar workpiece (40). The calculation of the control arrays takes into account the deviations in the variables monitored at the press (12), which may include force and position. While monitoring the press (12) based upon the HIGH  or LOW control arrays, each force value is compared to the values in the HIGH and LOW control arrays at the time of sampling. The press controller (14) is configured to monitor and control a high speed press (12) and provides control functions during the particular press (12) cycle in which unacceptable sample is taken.

Abstract: In a frequency synthesizer, a first pulse removing circuit (31) is connected between a reference signal generator (21) and a phase-frequency comparator (24). A second pulse removing circuit (32) is connected between a variable frequency divider (23) and the phase-frequency comparator. Responsive to first removing data indicative of a first pulse number, the first pulse removing circuit removes pulses from the reference signal that are equal in number to the first pulse number for a first predetermined cycle to produce a first pulse removed signal. Responsive to second removing data indicative of a second pulse number, the second pulse removing circuit removes pulses from the divided signal that are equal in number to the second pulse number for a second predetermined cycle to produce a second pulse removed signal. Responsive to a current command, a current controlling circuit may control current supplied from/to a charge pump circuit (25). A control circuit may be connected between the phase-frequency comparator and the charge pump circuit. A switch may be inserted between the loop filter and the voltage controlled oscillator. When the switch switches off a PLL, a D/A converter supplies a control voltage to the voltage controlled oscillator and a filter capacitor of the loop filter.
