Patent CA-2275489-C (CA)
Inventor: VAN ROOIJEN GIJS
IPC: C07K16/06
Filed: 1997-12-05
Granted: 2007-03-27
Abstract: A method for the separation of a target molecule from a mixture is described.  The method employs oil bodies and their associated proteins as affinity matrices for the selective, non-covalent binding of desired target molecules. The oil body proteins may be genetically fused to a ligand having specificity for the desired target molecule. Native oil body proteins can also be used in conjunction with an oil body protein specific ligand such as an antibody or an oil body binding protein. The method allows the separation and recovery of the desired target molecules due to the difference in densities between oil bodies and aqueous solutions.

Patent CA-2294083-C (CA)
Inventor: HUNT GROVER C JR
IPC: F16H3/74

Granted: 2005-10-18
Abstract: This smoothly automatic changing ratios gear mechanism for use in devices as small as toys and as large as the heaviest industrial machines is an arrangement of planetary gear sets (68, 72) which provide divergent ratio gear tracks (38, 40) driven by an arrangement of components (32) for dynamically positioning virtual fulcrum points (48) along virtual balance beams (54) thus automatically realizing a multiplicity of gear ratios. The gear ratio changes result from the relationship of the amplitude of force driving the system acting against the variable bias of spring and centrifugal forces that tend to keep the fulcrums (22) positioned to affect high RPM output. The gear tracks are arranged as minor images of each other and in a manner such that the ring gear (56) of an input planetary gear set (68) is tied to the sun gear (70) of an output planetary gear set (72) and vice versa thus forming divergent ratio gear tracks (38, 40). A low RPM output results from driving the input ring gear (56) and a high RPM output results from driving the input sun gear (58) with virtual fulcrum points (48) impinging upon virtual balance beams (54) so that gear ratios from the highest to the lowest and all the continuum between are possible. Using a sun gear to ring gear size ratio of 1/5 provides an output gear ratio ranging from 1/1 to 36/1.

Abstract: The present invention offers a manufacturing method that also makes sheet metal packets in what is referred to as the punch-packeting technology available that comprise a round or oval iron cross section. Lamellae are thereby punched from a tape and are provided with depressions at one side and with elevations at the other side that coincide with the depressions and lie opposite them, whereby the elevations in the form of at least two circular nipples are pressed into the depressions upon assembly of each packet. In one lamella per packet, this serving as separating lamella, cylindrical holes are punched instead of the depressions, the nipples of the neighboring lamella engaging into said holes. Lamellae are thereby punched from the tape that exhibit a different outside contour, particularly a different width, and are joined with one another to form a packet that at least partially comprises a round iron cross section. The sheet metal packet comprises graduated edges.

Title: Enhanced ngl recovery processes
Inventor: YAO JAME
IPC: F25J3/02
Filed: 1998-12-01
Granted: 2008-09-23
Abstract: The present invention is directed to methods for improving the efficiency and economy of processes for the recovery of natural gas liquids (NGL) from a gas feed, e.g., raw natural gas or a refinery or petrochemical plant gas stream. These methods may be employed with most, if not all, conventional separation methods using a distillation tower, e.g., a demethanizer or deethanizer column. In the methods of the present invention, a portion of a hydrocarbon liquid condensed on a chimney tray disposed below the lowest feed tray of the column is withdrawn from the tower. This withdrawn liquid hydrocarbon is expanded and heated to produce a two-phase system for separation into a heavy, liquid hydrocarbon product and a vapor phase for recycle to the column, preferably as a stripping gas. The withdrawn hydrocarbon liquid is preferably heated by indirect heat exchange with the inlet gas, thus reducing or eliminating the external refrigeration requirements of the process. The expanded, heated vapor recycled to the column increases the ethane and propane concentration in the column, this reducing the tray temperature profile and increasing the separation efficiency. Accordingly, the column may be operated at lower temperatures and higher pressures, resulting in significant energy savings and economies of operation.

Title: System and method for scheduling message transmission and processing in a digital data network
Inventor: WILLIAMS JAMES B
IPC: H04L12/56
Filed: 1999-04-23
Granted: 2008-11-18
Abstract: A system includes a plurality of computers interconnected by a network including one or more switching nodes. The computers transfer messages over virtual circuits established thereamong. A computer, as a source computer for one or more virtual circuit(s), schedules transmission of messages on a round-robin basis as among the virtual circuits for which it is source computer. Each switching node which forms part of a path for respective virtual circuits also forwards messages for virtual circuits in a round-robin manner, and, a computer, as a destination computer for one or more virtual circuit(s), schedules processing of received messages in a round-robin manner. Round-robin transmission, forwarding and processing at the destination provides a degree of fairness in message transmission as among the virtual circuits established over the network.  In addition, messages are transmitted in one or more cells, with the round-robin transmission being on a cell basis, so as to reduce delays which may occur for short messages if a long messages were transmitted in full for one virtual circuit before beginning transmission of a short message for another virtual circuit. For each virtual circuit, the destination computer and each switching node along the path for the virtual circuit can generate a virtual circuit flow control message for transmission to the source computer to temporarily limit transmission over the virtual circuit if the amount of resources being taken up by messages for the virtual circuit exceeds predetermined thresholds, further providing fairness as among the virtual circuits. In addition, each switching node or computer can generate link flow control messages for transmission to neighboring devices in the network to temporarily limit transmission thereto if the amount of resources taken up by all virtual circuits exceeds predetermined thresholds, so as to reduce the likelihood of message loss.

Abstract: Compositions and methods are provided for the enhanced in vitro synthesis of polypeptides. In order to improve the performance of in vitro protein synthesis reactions, metabolic inhibitors, or manipulation of a source organism, is used to diminish or avoid the action of enzymes responsible for undesirable amino acids production or depletion. A homeostatic system may be used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.
