Title: Solid tumor treatment method and composition
Inventor: MARTIN FRANCIS J
IPC: A61K38/095
Filed: 1990-10-19
Granted: 1997-03-25
Abstract: A liposome composition for delivering a compound to a solid tumor via the bloodstream. The liposomes, which contain the agent in entrapped form, are composed of vesicle-forming lipids and between 1-20 mole percent of a vesicle-forming lipid deriva-tized with hydrophilic polymer, and have sizes in a selected size range between 0.07 and 0.12 microns. After intravenous adminis-tration, the liposomes are taken up by the tumor within 24-48 hours, for site-specific release of entrapped compound into the tu-mor. In one composition for use in treating a solid tumor, the compound is an anthracycline antibiotic drug which is entrapped in the liposomes at a concentration of greater than about 50 µg agent/µMole liposome lipid.

Title: Method and apparatus for removing water from lubricants, coolants and the like
Inventor: SMITH DANIEL
IPC: B01D3/08
Filed: 1992-06-09
Granted: 1997-09-16
Abstract: A method of removing water from lubricants, coolants and the like consisting of the following described steps. Firstly, pass lubricants through a heater at a predetermined flow rate to  decrease  its  viscosity.    Secondly,  pass  the  heated lubricants through a vertical separation vessel which agitates the lubricants such that water entrained in the lubricants is released as steam. Thirdly, recirculate the heated lubricants repeatedly through the separation vessel at a recirculation flow rate that exceeds by many times the flow rate through the heater, thereby improving the degree of separation of water from the lubricants with each pass through the separation vessel.   Fourthly,  draw lubricants periodically from the separation vessel as the flow rate through the heater permits.

Title: Improvements in the in situ pcr
Inventor: BLOCH WILL
IPC: C12Q1/68
Filed: 1992-07-20
Granted: 2000-02-22
Abstract: Improvements to the in situ polymerase chain reaction (PCR), a process of in vitro enzymatic amplification of specific nucleic acid sequences within the cells where they originate, can be achieved by changing the way that the enzymatic reaction is started. Reaction initiation is delayed until the start of PCR thermal cycling, either by withholding a subset of PCR reagents from the cellular preparation until the preparation has been heated to 50° to 80°C, immediately before thermal cycling is begun, or by adding to the PCR reagents a single-stranded DNA binding protein which blocks reaction at temperatures below about 50°C. If the in situ PCR is performed on cellular preparations already attached to a microscope slide, thermal cycling also is facilitated by use of a thermal cycler sample block or compartment designed optimally to hold the microscope slide and any vapor barrier covering the slide.

Granted: 1999-07-13
Abstract: A memory controller which makes maximum use of any processor pipelining and runs a large number of cycles concurrently.  The memory controller utilizes different speed memory devices at each memory devices optimal speed.  The functions are performed by a plurality of simple, interdependent state machines, each responsible for one small portion of the overall operation.  As each state machine reaches has completed its function, it notifies a related state machine that it can now proceed and proceeds to wait for its next start or proceed indication.  The next state machine operates in a similar fashion.  The state machines responsible for the earlier portions of a cycle have started their tasks on the next cycle before the state machines responsible for the later portions of the cycle have completed their tasks.  The memory controller is logically organized as three main blocks, a front end block, a memory block and a host block, each being responsible for interactions with its related bus and components and interacting with the various other blocks for handshaking. The memory system includes a single chip which provides all of the address and control signals to a memory device so that a clock cycle can be saved because of reduced skew of the signals.  The signals are provided synchronously from the chip.

Abstract: OPTICAL MODULATORS AS MONOLITHICALLY INTEGRATED OPTICAL                       ISOLATORS Abstract An apparatus and technique for providing isolation for a signal source utilizing two or more modulators is described.  In particular, the apparatus generates a timed sequence of "open gates" that are synchronized to the data signal which permit transmission in a forward direction, and which attenuate a reverse direction signal.  Another embodiment attenuates primarily reflected light signals by utilizing a passive waveguide and a modulator.  The passive waveguide provides a propagation delay such that signals reflected from its end facet are attenuated by the modulator. The apparatus is suitable for use as an isolator for a light source in a high-speed optical fiber data transmission system.
