Title: Methods and compositions for the expression of biologically active eukaryotic cytochrome p450s in bacteria
Inventor: FISHER CHARLES W
IPC: C12N15/67
Filed: 1992-01-10
Granted: 2003-07-08
Abstract: Disclosed are methods and compositions for effecting bacterial expression of eukaryotic cytochrome P450 enzymes in a bi-ologically active form. Certain embodiments involve the expression of eukaryotic cytochrome P450 17.alpha.-hydroxylase which is ex-pressed in large amounts in an E. coli host in a biologically active form without the need for coexpression or admixture of a cy-tochrome P450 reductase. Methods and compositions are also disclosed for the construction of cytochrome P450 enzyme hybrids, incorporating the N-terminal 9 amino acids from bovine 17.alpha.-hydroxylase, which will enable many eukaryotic cytochrome P450 enzymes to be expressed in bacteria.

Abstract: A receiver for decoding N received branchword signals is disclosed. Illustratively, the branchword signals are generated by a tailbiting convolutional coder. The receiver stores received branchword signals in memory such that the branchword  signals are accessible in a logically circular sequence. The receiver then performs Viterbi updates on the logically circular sequence of branchwords, the sequence comprising more than N branchwords. Each Viterbi update provides a decision vector. The receiver stops performing Viterbi updates in response to anindication that Viterbi update decisions have become repetitive. A set of generated decision vectors resulting from the Viterbi updates is then modified in response to the indication. A decoded signal is generated by performing a Viterbi traceback procedure using the modified set of decision vectors. The indication that Viterbi update decisions have become repetitive may be provided by a predetermined fixednumber of Viterbi updates, the number reflecting an estimate of when said updatedecisions will likely become repetitive. The indication may also be provided by a comparison of decision vectors generated by Viterbi updates on the same stored branchword to determine whether the vectors are substantially equal. Or, the indication may be provided by a comparison of a pair of path metric vectors generated by Viterbi updates on the same stored branchword to determine whether differences between metric signals of one or more respective trellis state pairs of the path metric vectors are substantially equal. Modification of the set of generated decision vectors may include replacing a one or more decision vectors of the set with one or more later-determined decision vectors of the set. Alternatively, such modification may include extending the set of decision vectors by repeating previously determined decision vectors of the set.

Abstract: An electrical interruption device is disclosed in which an overcurrent protective device is provided to interrupt electric current flow on a sustained overcurrent current occurring.  The overcurrent protective device is characterized by a plunger which is held in tension against the force of a spring by a low temperature solder, and further in which a sleeve of insulating material, such as silicone, is provided about the plunger.  Preferably, the overcurrent protective device includes a housing, with the plunger disposed in the housing and having one end extending therefrom to provide electric communication with the remainder of the electric circuit.  The sleeve of insulating material preferably being located about the end of the plunger which extends from the housing.  On a predetermined condition causing the solder to melt, the plunger is released and under the force of the spring is moved to a position retracted within the sleeve, interrupting the current flow.  Advantageously, the overcurrent protective device may be used together with pulverulent arc quenching material.  The sleeve acts to isolate the pulverulent arc quenching material from the plunger and prevent its interference with the plunger as it is moved under the force of the spring.

Abstract: A tube cutter designed for cutting a pipe where access is limited to the interior of the tube only. A rotatable cutter head mounted at the end of an elongated drive shaft carries a plurality of cuffing wheels. The tube cutter is inserted into a tube to be cut from one end thereof using the elongated drive shaft to position the cutter head in the tube. When the cutter head is inserted into the predetermined location, a feed drive is energized which rotates a scroll head to cause the cutting wheels to move in a radial direction to advance and engage the interior surface of the tube in a concentric manner undergoing cutting. When the tube has been severed, the feed drive rotation is reversed to retract the cutting wheels into the rotatable head, so as to enable removal of the rotary tube cutter from the tube.

Patent CA-2199562-C (CA)
Inventor: WITT DAVID A
IPC: A61B17/072
Filed: 1997-03-10
Granted: 2005-12-06
Abstract: A linear surgical stapler having clamping and firing triggers pivotally mounted to the frame of the instrument for pivotal rotation toward a hand grip is disclosed. The clamping trigger is positioned between the firing trigger and the hand grip. Each of the triggers are pivotally mounted to pivot pins spaced from each other within the body portion of the frame. Pivotal rotation of the first trigger is independent of pivotal rotation of the second trigger. When the clamping trigger is pivotally rotated toward the hand grip, the clamping and firing transmission assemblies move distally in tandem. Before the first trigger is pivoted, the firing transmission assembly blocks pivotal rotation of the second trigger. When the first trigger is pivoted, the initial distal movement of the firing transmission assembly enables the firing trigger to be in a position to pivotally rotate, and therefore cause the firing of staples.  Additionally, a feature enabling the retention of the clamping trigger in intermediate and fully clamped positions is disclosed, where upon release of the retention feature, the clamping trigger can return to its original position by overriding the intermediate position.  Finally, although the invention is described with particular reference to a linear stapler containing clamping and firing triggers, it has broader applicability to any surgical instrument which has first and second triggers pivotally actuated to transmit work to an end effector for performing first and second surgical functions during a desired surgical procedure.

Abstract: Diamondlike carbon is deposited on a deposition substrate (46) in a deposition apparatus (40) that can be evacuated and backfilled with a carbonaceous gas. A plasma (68) is generated in the gas by heating a filament (62) within the chamber (42) to produce electrons, and positively biasing the filament (62) with respect to the deposition chamber wall (44) to accelerate the electrons into the carbonaceous gas. The carbonaceous gas dissociates and ionizes in the resulting plasma (68) to produce positively charged carbon ions. The deposition substrate (46) within the chamber (42) is negatively biased with respect to the deposition chamber wall (44), accelerating the carbon ions so that they are deposited onto the surface of the substrate (46).
