Title: Hay bale processor
Inventor: ROUSSEAU VICTOR
IPC: B02C18/24
Filed: 2003-01-14
Abstract: A hay bale processor (10) having a cylindrical rotatable drum (14) adapted to displace a bale of hay (156-157) over a grill (26) which has a plurality of spaced-apart parallel slot openings (27) which are adjustable to define an average fiber cut length. A rotor (28) driven by an electric motor (66-67) has cutting blades (35) projecting through the openings to contact a bottom face (159) of a bale of hay (160) displaced over the grill. The rotor has a driveable shaft (29) secured to a displaceable suspension mechanism (45) to displace the blades (35) in the openings and above the grill a variable distance depending on the resistive load applied to the blades of the rotor when a bale of hay is displaced over the grill. The displaceable suspension mechanism (45) is biased upwardly by an air cylinder (50) to maintain a substantially constant pressure on the displaceable suspension such that when the load on the cutting knives of the rotor are subjected to a force exceeding the predetermined pressure of the cylinder the rotor is displaced whereby a substantially constant drive torque is maintained on the electric motor driving the shaft (29) of the rotor (28).

Title: Activated sludge wastewater treatment system and method
Inventor: PROBST HENRY J
IPC: C02F3/00
Filed: 2001-09-06
Abstract: A improved activated sludge system and method for treating wastewater containing contaminants is disclosed which offers a broad array of advantage s over conventional activated sludge wastewater treatment systems, including smaller size, higher rates of operation, higher oxygen transfer efficiency, lower operating costs, and a substantially decreased level of excess sludge production. The improved activated sludge waste treatment system of the present invention has two processing tanks rather than the several tanks tha t are commonly found in activated sludge systems for treatment and sludge treatment equalizations, including anaerobic processes. The first processing  tank is a contact tank (42) which hosts a reaction which functions not merel y to digest the maximum amount of contaminants, but instead to bind contaminan ts to the microorganisms through absorption, adsorption, precipitation, or digestion so that they can then be removed from the liquid in a solid/liquid  separator (50). The activated sludge removed by the solid/liquid separator (50) is then supplied to a digester tank (54) containing a high concentratio n of activated sludge, where virtually complete digestion is achieved to minimize the volume of solids remaining. Activated sludge is provided from t he digester tank (54) to the contact tank (42) to facilitate the reaction in th e contact tank.

Inventor: PROPACH DAVID S
IPC: H04N1/32
Filed: 1994-11-15
Abstract: System and method for minimizing data bottlenecks in Low Data Rate Networks (LDRNs) that communicate facsimile transmissions. An LDRN is a facsimile network having a transmission data rate less than the data rate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless (e. g., cellular) LDRNs. The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate.

Filed: 2002-02-08
Abstract: Pulp fibers can be treated with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after redispersing the treated pulp fibers in the process water. One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. Th e dried fibrous web is treated with a water insoluble chemical additive thereb y forming a chemically treated dried fibrous web containing chemically treated pulp fibers. The chemically treated pulp fibers have an improved level of chemical retention of the water insoluble chemical additive and retain from between about 25 to about 100 percent of the applied amount of the water insoluble chemical additive when the chemically treated pulp fibers are redispersed in water.

Title: Method for the production of hydrogen and applications thereof
Inventor: ODLE ROBERT R
IPC: C10B57/12
Filed: 2002-03-05
Abstract: A method for the production of hydrogen gas. The hydrogen gas is formed by steam reduction using a metal/metal oxide couple to remove oxygen from water.  Steam is contacted with a molten metal mixture including a first reactive metal such as iron dissolved in a diluent metal such as tin. The reactive metal oxidizes to a metal oxide, forming a hydrogen gas and the metal oxide can then be reduced back to the metal for further production of hydrogen without substantial movement of the metal or metal oxide to a second reactor.  The reactor (400) includes refractory sidewalls (402) that are adapted to contain the molten metal mixture (404). As steam is introduced through the lance (408), iron from the metal mixture (404) oxidizes to iron oxide. The iron oxide rises and accumulates in a slag layer (406). A gas product (416) including hydrogen gas co-mingled with stream is extracted from outlet port (410).
Patent CA-2440255-A1 (CA)
Title: Gas compressor with drier and radio emission controls
Inventor: CHAN ANTHONY
IPC: B60S5/02
Filed: 2003-09-09
Abstract: A gas compressor unit according to the invention includes a single gas desiccant bed and condenser (which is inactive during the compression stage) inserted into the gas flow path of the compression cycle. In the case of a multi-stage compressor, the single gas desiccant bed is inserted between preferably the first and second stages. Moisture absorbed into this bed is periodically removed by exposing the bed to a regeneration cycle. The regeneration cycle employed is based on the closed re-circulation of gas present in the compressor and the desiccant bed itself, as well as other gas present in the re-circulation loop, when the unit suspends the vehicle-filling operation. Moisture removed from the desiccant bed is condensed and evaporated into the environment through a semipermeable membrane. The motor and motor controller are located with the compressor to minimize electro-magneti c emissions.

Abstract: This invention provides methods of regulating gene expression. An aptamer is positioned in a nucleic acid molecule along with a sequence encoding a transcriptional regulatory polypeptide. The aptamer disrupts translation of the transcriptional regulatory polypeptide when contacted with an aptamer-binding ligand. Gene expression levels can be either increased or decreased by the disclosed methods, depending on whether the transcriptional regulatory polypeptide is a repressor or activator, and the degree of the effect is dependent upon the dose of the ligand. Nucleic acid molecules, expression cassettes, expression vectors and cells useful in the gene regulation methods are also provided.

Title: Drowning alarm
Inventor: MANDEL YARON NAHUM
IPC: G08B21/08
Filed: 2003-11-07
Abstract: A drowning alarm is described. It is a device which activates an alarm when a person drowns, in order to alert bystanders to the drowning, so that they can save the drowning person. The device consists of two kinds of units: a portable unit, which is worn by each swimmer, and a base station, located on the pool deck or on the beach. The portable unit produces an alarm signal when the swimmer activates a manual alarm push button on the portable unit, or when a sensor on the portable unit detects that the unit is submerged in water for longer than a certain number of seconds. The alarm signal produced by the portable unit is ultrasound or audible sound, and it propagates in water to the base station. The base station activates an alarm such as a siren. The portable unit has a light emitting diode (LED), which is switched on when the portable unit activates an alarm. This identifies the portable unit which caused the alarm, so it helps deter intentional false alarms.
