Filed: 1998-01-22
Abstract: A paint roller frame includes a handle having a radial bore and a wire shank having an outer end for rotatably supporting a paint roller cover and an inner end rotatably received in the bore. The outer end of the wire shank extends at an angle relative to the inner end whereby turning movement of the inner end within the bore will cause a change in the orientation of the outer end and thus the paint roller cover supported thereby relative to the handle. Between the inner and outer ends of the wire shank is an intermediate portion extending at a right angle relative to the inner end which is spring biased into engagement with any one of a plurality of notches in an end wall of the handle surrounding the bore for retaining the outer end of the wire shank in any one of a plurality of different orientations relative to the handle. A pushing force applied to a button or the innermost end of the wire shank will cause the intermediate portion to move out of engagement with any one of the notches thus permitting the inner end of the wire shank to be turned within the bore to change the orientation of the outer end relative to the handle.

Title: Immunity against pasteurella haemolytica leukotoxin
Inventor: PRIDEAUX CHRISTOPHER THOMAS
IPC: C07K14/285
Filed: 1996-11-01
Abstract: Bovine respiratory disease (BRD) complex, shipping fever, or pneumomic pasteurellosis, is a multifactorial disease whereby a combination of viral infection, adverse environment and poor immune status may combine to predispose animals to bacterial infections. The exotoxin, or leukotoxin (Lkt), may contribute to pathogenesis by impairing the primary lung defenses and subsequent immune responses or by causing inflammations as a result of leukocyte lysis. The present invention provides a modified microorganism which produces an Lkt toxin, wherein said Lkt toxin is partially or fully inactivated. In a further embodiment of the present invention, there is provided a modified microorganism wherein an Lkt toxin operon including an Lkt structural gene and/or a post translational activator of the organism is partially or fully inactivated. The present applicants have found that a precursor of Lkt toxin has reduced toxic activity. Surprisingly, the Lkt toxin precursor is capable of inducing an immune response in an animal that offers cross protection against heterologous challenge with a microorganism which produces the Lkt toxin. A microorganism which naturally produces an Lkt toxin may be engineered to produce an inactive Lkt toxin precursor by eliminating the post-translational activator of the precursor product. Accordingly, in a preferred embodiment the microorganism is unable to produce a post-translational activator of the Lkt toxin precursor or produces an inactivated post-translational activator of the Lkt toxin precursor. The post-translational activator may be a product of the Lkt C gene.

Abstract: A method and system of managing call forwarding includes establishing criteria for selecting among possible links between nodes for forwarding calls from an originating node to a destination node. In the preferred embodiment, the selection of the possible links is made at a called node from which the call is to be forwarded. Based upon the administrable criteria, there is a determination as to whether an intermediate node along the call path between the originating node and the called node is to be selected for initiating the forwarding path. If an intermediate node is selected, a request is transmitted to the intermediate node to initiate the forwarding path to the destination node. On the other hand, if no intermediate node is selected, a determination is made as to whether to initiate the forwarding path from the originating node or from the called node. Again, the determination is made according to the administrable criteria. Typically, the most important factor in selecting among the nodes relates to minimizing the link necessary to connect the calling party to the forwarded-to party, thereby releasing links for other use within a network.

Title: Apparatus for the controlled heating of process fluids
Inventor: GIAMMARUTI ROBERT J
IPC: F28D15/02
Filed: 1999-02-23
Abstract: An apparatus for the controlled heating of a process fluid has a heater, a process fluid vessel containing the process fluid, and a bundle of thermosyphons extending between a burner chamber of the heater and the process fluid inside the vessel for transferring heat from the heater to the process fluid. Burners in the burner chamber are controlled to maintain the bulk temperature of the process fluid T BULK substantially within an operating range defined by preset upper T HIGH  and lower T LOW temperature setpoints. The burners can be turned on to maintain an outside metal temperature T EVAP of the evaporator ends of the thermosyphons above a preset dew point temperature T DEW to prevent corrosion. The burners can also be shut down if an outside surface temperature T OD of at least one of the condenser ends of the thermosyphons extending into the vessel exceeds a predetermined setpoint temperature T ALARM. Different configurations of condenser ends of the thermosyphons in the vessel may be utilized to enhance heating the process fluid.     The vessel and heater are separated and sealed from each other by a sealed chamber encasing the thermosyphons, which may also be used to preheat incoming combustion air for the burners.
