Title: Process for regulating the aeration of a waste water biological treatment tank
Inventor: LEFEVRE FANNY
IPC: C02F3/00
Filed: 1995-09-15
Granted: 2002-08-13
Abstract: In regulating the aeration of a biological treatment of waste water, using (i) a step of aerobic elimination of carbon, (ii) a step of aerobic nitrification, and (iii) a denitrification step in absence of oxygen, the oxidn.-redn. potential in a treatment system is measured continuously, the curve of development of this potential as a function of time is established, and the deriv. is calculated. When this deriv. tends towards 0, the deriv. and the value of the potential are correlated, to decide on the start, the continuation or the ending of the aeration.

Title: Pump device including multiple function collapsible pump chamber
Inventor: PETERSON ROBERT JAMES
IPC: B05B15/00
Filed: 1994-03-23
Granted: 2000-08-29
Abstract: A collapsible pump chamber (60) is provided which includes several functional elements of a pump device. For example, the collapsible pump chamber may be a bellows which includes a functional element (91) of an outlet valve, a functional element (82) of a biasing feature, and a functional element of a spin chamber (91). Consequently. a functional element of all of the downstream functions are incorporated into the bellows (60). This can significantly reduce costs; due to reduced tooling, and assembly, for example. In contrast, there are no upstream components incorporated into the bellows which enables the upstream or inlet end of the bellows to be wide open. This wide open upstream end of the bellows makes molding easier.

Abstract: An apparatus for packing fowl which includes first (12) and second (14) workstations. The first workstation is provided to receive the product to be packaged. A pusher mechanism (18) pushes the product from the first station between spaced plates (30, 32) into a plastic bag and then through the gates of a clipper mechanism. Advancement is slightly retarded by means of a blocking mechanism (34) to thereby insure that the product is tightly retained within the flexible plastic bag. The bag and product are thereby moved to the second station at which time a holding bar preliminary closes the bag. Thence, gates close and gather the neck of the bag and a metal clip is advanced by means of a punch in a clip channel defined by the closed gates. The clip is thereby fastened about the neck of the closed plastic bag and the excess tail of the bag is cut by means of a knife. Trap doors then release the packaged product onto a conveyor belt, a new bag is positioned on the spaced, guide plates, and the apparatus is ready to recycle.

Abstract: A torque-angle wrench (100) is pro-vided with a handle (104) for applying torque, such as to a fastener or bolt, through a tightening angle, at a rotational angular velocity. A piezoelectric gyro-scopic sensor device (102) including cir-cuitry for vibrating an oscillating body is coupled to the wrench. As the wrench is rotated through the tightening angle, its rotational angular velocity causes the vi-brating body to alter its direction of vibra-tion. The new vibrating pattern is sensed and converted, by appropriate sensing cir-cuitry, into an electrical signal proportional in intensity to the rotational angular veloc-ity of the wrench. The electrical signal can be electronically processed by appropriate conversion and display circuitry to provide a visual indication of the tightening angle. Such conversion and display circuitry can be integral with the wrench or as part of an adaptably coupled meter non-integrally connected to the sensor device.

Abstract: The present invention relates to a method and apparatus for the encapsulation of biologically-active substances in red blood cells, characterized by an optionally automated, continuous-flow, self-contained electroporation system (5) which allows withdrawal of blood from a patient, separation of red blood cells, and optional recombination of blood plasma and the modified red blood cells thereby producing blood with modified biological characteristics. The present invention is particularly suited for use to encapsulate allosteric effectors of hemoglobin, thereby reducing the affinity of erythrocytes for oxygen and improving the release of oxygen from erythrocytes in tissues. The blood is introduced into the system (5) at inlet (11) and mixed with an anticoagulant (27). The blood and anticoagulant mixture is passed through a filter (18) and to a blood separation and wash bowl (44). Plasma and white blood cells are admitted into the plasma reservoir (89) while the red blood cells are retained in the wash bowl (44). The separated red blood cells are pumped out and admixed at junction (67) withan IHP solution from reservoir (50). This mixture is cooled by cooling coil (68) and then pumped to electroporation chamber (72) for treatment.

Abstract: A retrievable mill guide and anchor assembly is provided for use in forming a side wall window in a vertical subterranean well casing for subsequent connection to the casing of a lateral bore liner member extending through the casing window. The mill guide extends upwardly from the top end or the anchor. With the assembly in its run-in orientation, a milling pipe with a first mill bit on its lower end is releasably locked within the upper mill guide end, and pressurized fluid within the milling pipe is used to hydraulically set the anchor in the casing. After the anchor is set, the first mill bit is rotated, lowered and deflected by the mill guide to engage and form an initial opening in the casing side wall. The milling pipe is then removed from the casing, the first mill bit is replaced with a second mill bit, and a specially designed retrieval collet is installed on the milling pipe. The milling pipe is then lowered into the casing, and the second mill bit is used in conjunction with the mill guide to enlarge the casing side wall opening to the final desired window size. The retrieval collet is then latched into the upper mill guide end and pulled up to sequentially release the anchor and pull the mill guide and anchor assembly out of the casing with the milling pipe.

Inventor: YUN LOUIS C
IPC: H04B17/00
Filed: 1997-10-10
Granted: 2004-12-07
Abstract: An adaptive method for channel assignment (500) in a cellular multiple access wireless communication system that has a cell station (100) and a number of subscriber stations (25, 26, 27) augments existing channel assignment protocol and thus is downward compatible with existing time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDM,4), and spatial division multiple access (SDMA) system protocols. The method adaptively determines the power required for establishing an acceptable quality connection between a subscriber station (25) and the cell station (100) and provides an early warning trial signal for advising existing connections that a new connection is about to be established. The early warning, followed by a pause, provides a basis and a time interval for taking corrective interference action if the trial signal indicates that an unacceptable level of interference will result if the trial connection is established. The early warning signal and associated pause are useful for intracellular and intercellular interference management.
