Inventor: MARX GERARD
IPC: A61K38/43
Filed: 1995-02-08
Granted: 2007-04-03
Abstract: The present invention describes a biologically compatible bioadhesive composition fibrin glue and liposomes for use in mammals, including humans. Fibrin glue of the invention comprises fibrinogen and thrombin which are mixed together in various modes with liposomes and applied to a site of injury, to a wound, or to a surgical or nonsurgical incision or opening. In accordance with the invention, the liposomes are embedded within the fibrin glue after coagulation has occured, and may release bioactive substances contained within their acqueous interiors to promote healing and protection during the recovery process. The bioadhesive composition of the invention promises to maintain hemostasis after surgeries and improves upon existing glues or gel formulations due to its complete biological compatibility, its formation in situ, and its provision of bioactive therapeutics via entrapped liposomes directly to the site. Long-lasting biophysical and biomechanical properties as well as therapeutic value are imparted to the fibrin glue components by the liposome component of the composition.  The bicompatible fibrin glue and liposome composition is also amenable for fabrication into films, coatings, or membranes for in vitro and in vivo uses.

Abstract: A welding torch which combines features of both laser and plasma-arc welding torches. A laser beam is directed by an objective lens so that it is co-linear with the central axis of a plasma-arc torch. The laser beam passes through a planar or conical cathode electrode placed at the bottom orifice of the torch. A coaxial aperture having a diameter less than that of the laser beam is drilled into the cathode to allow the laser beam to pass through the cathode. A constricting nozzle is placed under the cathode, with the laser beam passing through the axis of the nozzle. As with a standard plasma-arc torch, a gas is forced through a chamber having the cathode and nozzle at its bottom end. As the cathode is heated by the laser radiation, the gas is ionized and a plasma-arc is formed. As the laser beam passes through the nozzle, it comes to a focus and interacts with the plasma-arc formed between the cathode and a workpiece. The resulting interactions between the plasma-arc and laser beam form a plasma-laser discharge which acts to additionally constrict the laser beam and plasma-arc and increase the energy density of the welding spot formed on the workpiece.

Abstract: Composite  polymer dispensers  capable  of controlled release of semiochemicals have been developed.  The dispensers make use of a solid elastomer matrix reservoir which is at  least partially surrounded by a permeable release rate controlling polymer membrane.   The matrix materials are polyurethanes compatible with many types of semiochemicals and additives.  The release rates of semiochemicals from the dispensers can be varied over a wide range by manipulation of the reservoir conditions and by selection of the type of permeable polymer membrane surrounding the device.  The dispensers can have a variety of forms and can be produced by a simple process.  The semiochemical devices produced by this method are useful for managing  insect  and other pests  through attraction to traps, for population monitoring or for mass trapping.  The devices may also be used to dispense  anti-aggregation pheromones or repellents in addition to use for mating confusion or disruption.

Abstract: Raw waste is first composted into a bioreactor to produce a crude compost. At the outlet of the bioreactor, the crude compost is separated from the non-compostable waste fraction. Then, the separated crude compost is conveyed to a compost maturation area where the crude compost is recycled. The composting process is conducted in at least one closed building area maintained at a negative pressure for aspirating and directing odorous substances to a biofilter. This biofilter extracts the odorous substances whereby the process can carried out in urban areas without affecting the air quality and accordingly without disturbing the neighbourhood. Also, the composting process can be run with a number of employees as small as three, to produce high quality compost substantially free of pathogenic microorganisms.

Abstract: A system and method for providing telemarketing services through a hypertext network that interconnects a telemarketing server system with a customer computer and an agent computer.  The telemarketing server accepts a telemarketing request from the customer, and forwards the request to the agent if the agent is available, and to a queue if the agent is not available.  When an agent receives a request, communications are either established between the customer and agent at once, or else scheduled for a later time.  Telemarketing functions are implemented separately from media transport functions through a hypertext network such that the need for geographic centralization of telemarketing agents is eliminated.
