Patent CA-2394830-A1 (CA)
Inventor: MATCHEM TODD MICHAEL
IPC: A01G31/02
Filed: 2002-08-08
Abstract: A hydroponic plant growing apparatus is known to have plural open top flat bed containers which are nested one on top of the other in a vertical orientation.  The upper container typically supports individual pots containing a sterile support media such as rock wool, where as the bottom container typically forms a storage reservoir for the nutrient enriched solution.   In operation, the nutrient solution is circulated from the lower container to the upper containers. The three common methods of nutrient supply to the plants are (1) Drip irrigation (2) wick irrigation and (3) flood irrigation. Although these hydroponic systems have proven useful in their application, there exists a need for improvement to their overall operation.   In this invention, the storage reservoir for the nutrient solution is constructed of fiberglass and incorporates a large drain hole covered by a drain plug. The plug is hinged to the tank on one side and the bottom of the reservoir is sloped in the direction of the drain. The reservoir sits on a base, which allows the top of the reservoir to lay level and suspends the reservoir bottom off of the floor. Common plumbing is easily attached to the drain hole and routed to a typical sewage system or appropriate outdoor area. A chain is attached to the plug thereby making it assessable from above the water level. Incorporated in the drain is an overfill tube. The reservoir is also equipped with an automatic filling valve. The fill valve is actuated by a float, which rises and falls with the water level. A fill tube is located at the opposite and upper end of the reservoir and is connected to the fill valve. By supplying water to the reservoir opposite the end that the water drains, a rinsing action is created when the reservoir is being emptied. In addition to an improvement in reservoir design, prior systems fail to properly address the need for adequate and even airflow to each individual plant. In this invention, the upper container is a two piece lid design with plural openings for pots and is nested on top of the reservoir. The pots fit tightly into the bottom section of the two piece lid while an air gap is provided in the upper section around each pot. The two piece lid acts as an air duct. The lid has a supply air port which enters the cavity between the two lids. When air is blown into the two piece lid, air escapes through the opening around the pots and the plants receive full coverage airflow.

Patent CA-2397955-A1 (CA)
Inventor: SIMONS MICHAEL
IPC: A61K38/00
Filed: 2000-12-27
Abstract: The present invention provides both a method and means for regulating I.kappa.B.alpha. degradation, NF.kappa.B activity, and NF.kappa.B-dependent gene expression within living cells, tissues, and organs in-situ. The selective regulation is performed using native PR-39 peptide or one of its shorter-length homologs, for interaction with such I.kappa.B.alpha. and proteasomes as are present in the cytoplasm of viable cells. The result of P R- 39 peptide interaction with I.kappa.B.alpha. is a selective alteration in th e intracellular proteolytic activity of proteasomes, which in turn, causes a reduction of I.kappa.B.alpha., a decrease of NF.kappa.B activity, and a down - regulation of NF.kappa.B-dependent gene expression.

Abstract: A perfusion incubator having a fluid conditioning unit, a well assembly and a well assembly heating unit, a peristaltic pump and a fluid collection unit. The well assembly has a number of wells each having a transparent lid and a fluid inlet and a fluid outlet. An illumination device is under the well so that the cell being cultured in the well assembly can be observed by means of a microscope. Each fluid inlet is positioned so as to allow a tangential entry of fluid to the well at a mid point in the well, and each fluid outlet is above the fluid inlet with the cell to be cultured in a lower portion of the well so that flow of fluid in the well is formed into a vortex which tends to draw fluid from around the cell without direct flow over the embryo.

Title: Termination number screening
Inventor: MARCHAND DEAN
IPC: H04M1/677
Filed: 2000-12-18
Abstract: Terminating number screening to block portable billing products from terminating to a designated high fraud domestic or international terminating numbers. When a call is placed and it is billed to a portable billing product (104, 128), the dialed digits of the terminating number is verified against the terminating number screening database (108, 118). If the sequence of dialed digits is found in the terminating number screening database, the call is denied (112, 122). The caller is then informed that they cannot place a call to this destination and asked if there is another terminating number they wish to call (124). If the sequence of dialed digits is not found in the terminating number screening database, the call is allowed to process without interruption (110, 120). The purpose of this functionality is to protect the Operator Service network from repeated fraudulent calling to individual telephone line numbers either international or domestic.

Title: Gas pressure regulator
Inventor: BAYER DETLEF
IPC: G05D16/06
Filed: 2001-04-17
Abstract: The aim of the invention is to provide a gas pressure regulator which functions with repetitive accuracy even with the smallest possible throughpu ts and which simultaneously maintains a zero cut-off. In addition, the inventio n should allow gas burners which are operated within a wide modulation range t o be ignited, while keeping the internal pressure loss as minimal as possible.  The production costs and the number of sealing points should also be as low as possible. To achieve these aims, the chamber (19) on the inlet side and the chamber on the outlet side (22) of the gas pressure regulator, together with  the passage that is available for regulating the pressure, are also connecte d by one or several separate openings (34) which respectively form a seat (35)  for a closure body (33) that is allocated to said openings and that is displaced in an axial direction against the seat. Said closure body is, in turn, connected to an armature (31) of a solenoid valve. The gas pressure regulator, which regulates the initial pressure in a gas line that supplies a gas burner, can also feed the gas burner the required initial quantity of ga s for ignition.

IPC: F02G1/04
Filed: 2002-11-25
Abstract: A cycle engine converting thermal energy to electricity includes a cylinder housing having a piston having two oppositely disposed heads and mounted for reciprocating inside the cylinder. The cylinder is disposed between a hot zone to supply hot gas to one piston head and a cold zone to receive discharged hot gas from another piston head, and to transform the discharged hot gas into a liquid. The hot zone supplies hot gas into the first piston head, while the second head discharges hot gas to the cold zone. This action creates a pressure differential between the two piston heads that causes the piston heads to move in one direction. Thereafter, the hot zone supplies hot gas to the second piston head. while the first piston head discharges hot gas to the cold zone. thereby creating pressure differential between the heads causing the piston to move in another direction. The piston is provided with a permanent magnet coupled to electric coil. When the piston reciprocates, it creates a magnetic influx in the electric coil, which is transformed into electricity in the coil.
