Title: Surgical stapler
Inventor: THORNTON CURTIS W
IPC: A61B17/068
Filed: 1990-12-05
Abstract: A surgical stapler, preferably in a single use disposable form, comprises a combination of a staple feeding mechanism and a staple forming mechanism secured in a frame and an actuating trigger functionally connected to both the staple feeding mechanism and the staple,forming mechanism, wherein the staple feeding mechanism includes a rail to guide contained staples serially to a staple forming position and a shuttle in association with the rail as a movable staple retaining cover, the shuttle being functionally connected to the trigger for movement in the same direction and the same time as the staples. The rail includes a pair of spaced apart flexible members which support the next staple to be deformed but which flex to move out of the staple path at the onset of deformation. The staple after formation is positioned between the members so that there is no interference between the rail and the deformed staple.

Title: Lobster transport or holding system
Inventor: FLYNN SHERIDAN
IPC: B65D85/50
Filed: 1990-12-14
Abstract: ABSTRACT          This invention relates to a container for the storage or transportation  of  live  lobsters.    The  object  is  to provide a facility for maintaining lobsters alive during transportation  or  storage.    A  container  is  provided comprising an outer shell, partitions and shelves within the shell to provide individual storage compartments for lobsters.   The shelves are shaped and located so that there will be space for the circulation of water through the storage compartments.   There is also access to the storage compartments  for the  insertion and removal of lobsters.   The water is aerated and this aerated water circulates  through  the  storage  compartments.    Other inventive  features  of  the  preferred  aspect  of  the invention include retaining means such as flexible posts at the open ends of the storage compartments, removable inserts  which  can  be  located  at  adjustable positions depending  on  the  size  of  the  lobster  and  special provisions  for  aeration  of  stacked  containers.    A transport system has also been designed to be compatible with a refrigerated transport container and a storage system including a tank.
Patent CA-2041299-A1 (CA)
Title: Splice tray and method
Inventor: JUSTICE BARBARA LYNN
IPC: G02B6/255
Filed: 1991-04-26
Abstract: A splice organizing tray can protect the optical fibers from excessive stress if the fibers stored in the tray are organized in paths which do not require bending of the fibers beyond their approved bend radius, which do not require the fibers to cross, and which maintain the fibers in contact with the support substantially all the time.        The tray has a convex bottom wall to urge the fibers against the edges of the tray, a recessed splice support area, and resilient snaps to engage the ends of the splices to permit the splices to be placed closer together. Holes below the splices afford the removal of the splices without danger to the adjacent fibers.

Title: Process for generating powerful acoustical pulses by incorporating aluminum electrodes or high voltage/high current capacitors (or superconducting field coils) in the discharge circuits of plasma sparking devices
Inventor: BRYDEN ARTHUR D
IPC: G01S15/00
Filed: 1991-04-29
Abstract: Process for generating powerful acoustical pulses by incorporating aluminum electrodes or high voltage/high current capacitors (or superconducting field coils) in the discharge circuits of plasma sparking devices ABSTRACT    A plasma sparking device - "plasma gun," "plasma jet source" or "sparker" - is an electrically operated device that is used to generate acoustical pulses in underwater seismic range-finding and imaging. However, if the discharge power of a submerged plasma sparking device can be suitably stepped up (high current at high voltage), it can be made to produce acoustical pulses that are locally lethal, damaging or otherwise intolerable to a wide variety of unwanted marine organisms, including zebra mussels, thereby controlling their propagation in defined areas.          Very powerful acoustical pulses from underwater or liquid-immersed plasma sparking devices have a number of other potential applications as well. The applicant has solved the problem of producing such high-powered acoustical pulses from liquid-immersed plasma sparking devices by the employment of high current/high voltage liquid dielectric capacitors (hereafter called oil-filled capacitors) or cryogenically cooled superconducting field coils in a plasma sparking device's spark discharge circuit. The applicant also has found that feeding electrodes made out of aluminum also significantly increase the power of the plasma plume at discharge and the consequent acoustical pulse.

Abstract: In a solid state extrusion process a semi-crystalline polymer billet in a pressure chamber is forced through a die at the end of the chamber, with the polymer passing through the die at a temperature between 30.degree.C below the alpha-crystalline temperature and the melting point of the polymer to form an oriented polymer profile. The pressure chamber is heated to about 0.500.95 of the melting point of the polymer and the die is heated to about 0.65-1.2 of the melting point of the polymer, with the die preferably being heating to at least 5.degree.C warmer than the billet. A haul off stress on the profile extruded from the die is maintained between at least 0.5 MPa and a maximum amount without plastic deformation of the extrudate to obtain an oriented profile having a cross-sectional area greater than 0.5 cm2 at an extrusion rate greater than 0.5 m/min.

Title: Subtilisin mutants
Inventor: CALDWELL ROBERT M
IPC: C12N9/14
Filed: 1990-10-26
Abstract: Novel carbonyl hydrolase mutants derived from the DNA sequences of naturally-occurring or recombinant non-human carbonyl hydrolases are disclosed. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to generate the substitution of one or more amino acid residues in the amino acid sequence of a precursor carbonyl hydrolase. Such mutant carbonyl hydrolases have properties which are different from those of the precursor hydrolase and are especially useful in detergent formulations.  The substituted amino acid residues correspond to position +123 and/or +274 in Bacillus amyloliquefaciens subtilisin.

Filed: 1992-04-24
Abstract: In a digital communication system where a received stuff-synchronized TDM signal is demultiplexed into data signals each containing a sequence of frames. Each frame contains a pointer to indicate the start timing of the frame and specify positive, negative or zero destuffing. A pointer is detected from each data signal and compared with a previous pointer of the data signal stored in a memory. From this comparison the type of destuffing to be performed on a frame is determined, and in response to it, +1, -1 or 0 is added to the previous pointer to produce a current pointer, which is then used to rewrite the previous point. A binary clock count value is generated by a single phase counter and compared with the current pointer to generate a start-of-frame signal if it equals the current value.
