Title: System for cleaning contaminated water
Inventor: GILLHAM ROBERT WINSTON
IPC: C02F9/00
Filed: 1992-04-24
Granted: 2002-07-02
Abstract: Water contaminated with halogenated organics, including chloroform, trichloroethane, solvents, pesticides, etc. is treated by passing the water through a permeable mixture of activated carbon and iron fillings. When the mixture is brought to a negative Eh voltae, the metal causes the contaminants to undergo chemical breakdown.  The activated carbon acts to retard the contami-nant, giving it a long residence time close to the iron. The negative Eh conditions demand oxygen exclusion, such that a favoured application is to place the mixture in a trench below the water table in an aquifer, in the path of a plume of contaminant. The mix-ture may also be contained in a tank above, or in, the ground. An inert filler material, such as sand, may be included in the mix-ture.

Title: Child's toy vehicle having a safety device
Inventor: RODRIGUEZ-FERRE JOSE MANUEL
IPC: B60K28/02
Filed: 1993-12-13
Granted: 1997-09-09
Abstract: It comprises a vehicle (1)  including a receiver circuit which  may  be  enabled  by  the  electromagnetic  signal emitted by a remote control  (17), handled by an adult, and a pushbutton (15), in series with the motor (19), to be depressed by the child driving the vehicle. A switch (14) breaks the supply to the receiver circuit, disabling it,  at the same time as it makes a bridge across the power supply and the child operated pushbutton (15).            The invention is applicable to children's toy vehicles driven by very young children, so that an adult located remotely can break the motor supply to stop the vehicle at any given time, for safety purposes.

Granted: 2000-05-16
Abstract: A clock is phase shifted by an amount controlled by the value of a control signal by establishing at least several discrete delay times to be imposed on the clock. The control signal value controls selection of the imposed discrete delay time. An analog-to-digital converter of a phase locked loop responds to intelligence representing variable phase bits and the selected phase shifted clock to control the signal value.      The selected replica is derived by at least several cascaded substantially equal time delay units. In one embodiment, a multiplexer responds to the clock and the signal value, with is Gray coded, to control connections from one of the delay units to an output terminal. In another embodiment, the number of cascaded delay units interposed between the clock and an output terminal is controlled by the signal value. One use of the phase shifter is in a phase lock loop.

Abstract: The valve comprises a first pressure chamber (2), an outlet chamber (6) and a valve body (8), cooperating with a first valve seat (12), and also a second pressure chamber (13) delimited by the valve body. The valve body (8) comprises a control piston (22) which cooperates with a second valve seat (26) and is movable between a closing position and an open position. The control piston delimits in a valve chamber (17) a first sub-chamber, which faces away from the second valve seat (26) and communicates with the first pressure chamber (2), a second sub-chamber, which faces the second valve seat (26) and communicates with the outlet chamber (6), and a middle sub-chamber, which surrounds the cylindrical surface of the control piston and communicates with the second pressure chamber (13). The control piston (22) establishes in the closing position transfer communication between the first and the middle sub-chamber, and in the open position transfer communication between the second and the middle sub-chamber. The valve body (8), which is designed as an equalizing piston, adjusts itself always like a follower piston with respect to the control piston (22) which may be driven by a controllable positioner (19), and is controllably displaceable thereby between the first valve seat (12) and the various open positions.

Two longitudinally extending actuators are mounted on the frame. Both actuators are lying in the pinion plane.  Each actuator is adjacent to the pinion on a respective side thereof, namely right and left, and bears a corresponding sprocket coplanar with the pinion plane and rotatably connected to their free end. To link the elements together, there is provided a chain in mesh with the sprockets and the pinion. The chain has ends rigidly attached to the frame of the implement.  In use,  the implement is rotated as the actuators  are  operated  in  opposite  directions.  The mechanism provides a simple and reliable construction for rotating a tree-felling implement that is capable of rotating the implement with reference to the boom plane in both directions and according to a wide range of angles.

Abstract: In a shared users printing system, with an electronic printer for printing print jobs of respective different plural users, with a printer mailboxsystem for receiving the print jobs in multiple mailbox bins of a limited sheet capacity, and a sheet distribution system for automatically directing into different individual mailbox bins assigned to different users their respective print jobs, with at least the initial sheets of a particular user directed to a selected first mailbox bin, a control system controls the sheet distribution system in a job splitting program in accordance with the maximum sheet stacking capacity of the first bin to divert subsequent printed sheets being printed for that user which would exceed the maximum capacity to at least one other bin and in coordination therewith automatically prints and inserts a special banner sheet as the last sheet inserted into the first bin, as the top sheet, with a readable indication that the subsequent printed sheets for that user are being so diverted to other bin(s), and indicating their locations. The banner sheets are only printed for such job splitting, and not for normal unsplit print jobs. Another special banner sheet is automatically printed and inserted into the other bin with the diverted subsequent printed sheets in a position to identify them. The otherbin may be a higher sheet stacking capacity overflow tray which is commonly shared by plural users.
