Title: Method for nonspecific cellular immune stimulation
Inventor: GRISTINA ANTHONY G
IPC: A61K35/744
Filed: 1993-04-27
Abstract: 2135784 9323079 PCTABScor01 A non-specific host defense cell augmentation technique for enhanced microorganism killing utilizes any phagocytosable biocompatible particle to prime macrophages for enhanced oxidative response and bacterial killing. Patients can have the benefits of primed macrophages in one to four days, and experiments have demonstrated over a 100-fold increase in oxidative potential within this time period. The oxidative response and killing potential is non-immunospecific, meaning not one microorganism, not a vaccine, and broadly applicable simultaneously to bacteria and viruses as well as tumor cells. The effects have been demonstrated to have a seven day duration indicating non-tissue toxic residual effects and potential for repeated use at monthly intervals.

Filed: 1995-01-30
Abstract: A mobile unit communication system comprises: mobile units; a TDMA base station for transmitting and receiving a TDMA signal having a first frame to/from mobile units within a service area thereof in a TDMA/TDD manner; and a CDMA base station adjacent to the TDMA base station, for transmitting and receiving a CDMA signal having a second frame to/from mobile units in a CDMA/TDD manner, at least one of these base stations having a frame synchronizing circuit for detecting a phase between the first and second frames and synchronizing the first and second frames according to the detected phase. Each mobile unit has a first circuit for communicating with the TDMA base station in a TDMA mode; and a second circuit for communicating with the CDMA base station in a CDMA mode. First and second frames have the same length and are synchronized to eliminate the necessity of synchronizing operation when the mobile unit moves to the other service area. A unique word attached to a framed data is commonly defined between the TDMA and CDMA signals, so that a unique word detection circuit can be used commonly. The TDMA and CDMA signals have the same frequency band, so that the antenna portion can be used commonly. The TDMA and CDMA signals have the same amount of data per channel in a frame, so that modulation and demodulation circuits can be used commonly.

Inventor: LE MINH QUANG
IPC: B05B3/04
Filed: 1995-10-20
Abstract: A reduced size tank cleaning machine that has an impeller rotated by an inlet stream is disclosed.   The impeller turns a shaft connected to a sealed planetary gear train that causes the tank cleaning machine to rotate about an axis, and this rotation causes a set of nozzles to rotate about a second axis.  The fluid from the inlet stream exists through a port located between the impeller and the gear train and through the spray nozzles.   Thus, the planetary gear train drives the tank cleaning machine about a first axis and a second axis.  The design disclosed is preferably constructed so that it can be inserted into an opening that is about three inches (3.00" = 76 2 mm) in diameter.  Methods of cleaning vessels are also disclosed.

Inventor: BAZIUK MORRIS
IPC: B60P1/60
Filed: 1995-11-16
Abstract: A vacuum truck includes a storage tank mounted on the truck frame and a vacuum pump for drawing air into the storage so that a vacuum hose extending from material to be excavated to an inlet of the storage tank carries the material into the tank for discharge from the air prior to passage of the air to vacuum pump. A filter system is provided in the ducting between the storage tank and the vacuum pump to extract particles and moisture from the air. The filter system includes a chamber attached along one side of the cylindrical storage tank with that chamber having a plurality of curtains attached to an upper wall of the chamber and suspended vertically across the chamber. Each curtain is formed from a plurality of chain lengths suspended by a top link of the chain to a bracket at the top wall of the chamber. The lengths are arranged side by side to form a full curtain across the width and height of the chamber. As the lengths of chain are attached only at the upper wall, they are free to dance as the vehicle is transported from place to place and move away from the bottom surface of the chamber when the chamber is tilted with the storage tank for discharge of material. The dancing action provides a self-cleaning effect on the chain filters with the material dropping to the bottom wall and as the chains move away from the bottom wall in the tilting action the material is free to slide toa discharge opening at the rear of the chamber.
