Title: Method for generating proteolytic enzymes specific against a selected peptide sequence
Inventor: DAVIS CLAUDE GEOFFREY
IPC: C12Q1/37
Filed: 1995-12-21
Abstract: The present invention describes methods for screening or selecting novel proteolytic enzymes. These enzymatic functions can be selected from isolated chromosomal DNA libraries or from pools of mutagenized DNA encoding a proteolytic function. In particular, the selection method of the present invention, a phage gene is chosen that encodes a gene product necessary for the production of a phage. The phage carrying the modified gene is introduced into a host. Also, DNA libraries present within a cloning vector are introduced into host cells. The host cells are grown under conditions where the introduced libraries are expressed in the host cells. The presence of an enzymatic function capable of cleaving the target peptide is identified on the basis of production of infective phage.

Title: Greywater heat recovery device using a combined thermosyphon/heat pipe principle
Inventor: PROSKIW GARY
IPC: F24D17/00
Filed: 1997-10-09
Abstract: A heat recovery device recovers heat from a waste water pipe or the like. The device includes an evaporator chamber surrounding a length of the pipe. The chamber contains a refrigerant in both liquid and vapour states. A wick surrounding the pipe within the evaporator chamber extends into the liquid state refrigerant. A vapour outlet from the evaporator chamber above the liquid refrigerant leads to a condenser chamber around a container for liquid to be heated. The condenser chamber has an outlet connected to the evaporator chamber for delivering liquid refrigerant from the condenser chamber to the evaporator chamber. Heat in the pipe evaporates refrigerant from the wick. The evaporated refrigerant then travels into the condenser chamber where the cold surface of the water chamber extracts heat from the refrigerant and condenses it to be discharged back to the evaporator chamber. The water container in the condenser chamber is connected into the hot water system.

Abstract: A system for remotely monitoring personnel status includes a plurality of sensors disposable on a soldier or other person for developing signals which may be used to determine the physiological status.   The sensors communicate with a soldier unit which can process the information to ensure that the sensor data falls within acceptable ranges and communicate with remote monitors. The soldier unit also includes a global positioning system.    By using  the  sensor  data  and  the  global positioning system, leaders and medics can quickly and accurately track and treat casualties in battle.  The system enables more rapid location of the casualty, as well  as  remote  triage/initial  diagnosis,   thereby assuring that those who are most in need of treatment are attended to first.  Typically, the system monitors both body surface and ambient temperature, heart rate, shivering, motion status and body condition. Additional sensors can be provided to supply information on other physiological parameter which may be desired for more thorough diagnosis.  The physiological information may be stored and kept with the soldier to enable improved care as the soldier is moved to higher levels of care.

Inventor: MORSEY MOHAMAD A
IPC: C12N15/09
Filed: 1996-10-17
Abstract: The invention relates to a culture system for stable and high-level production of DNA contained on recombinant plasmids, and to the bacteria and plasmids which comprise the culture system. The bacterial cell chromosome is irreversibly altered, in one embodiment, so as to produce a substance toxic to the bacterium; in a second embodiment, so as to render the cells unable to synthesize and assimilate an essential metabolite, and, in a third embodiment, to be incapable of producing a required intracellular protein that does not lead to a secreted product. In every case, the recombinant plasmid includes genetic material which functionally complements the chromosomal alteration. If the DNA on the plasmid is to be used in therapeutic applications or for administration to eukaryotes, the genetic material will have no functional or structural equivalent in eukaryotic cells, and will not result in production of mRNA or a polypeptide that acts on any eukaryotic cell component. Any peptide produced is, desirably, not toxic to the bacterial cells.
