Abstract: Multivesicular Liposomes Having a Biologically Active Substance Encapsulated Therein In the Presence of a Hydrochloride Abstract of the Disclosure Disclosed are large multivesicular liposomes containing biologically active substances, the multivesicular liposomes having defined size distribution, adjustible average size, adjustible internal chamber size and number, and having substantially higher encapsulation efficiency and substantially slower leakage rate of the biologically active substance than in the previous art.  The process comprises dissolving a lipid component in volatile organic solvents, adding an immiscible aqueous component containing a hydrochloride and one or more biologically active substances to be encapsulated, making a water-in-oil emulsion from the two components, immersing the emulsion into a second aqueous component, dividing the emulsion into small solvent spherules which contain even smaller aqueous chambers, and then evaporating the solvents to give an aqueous suspension of multivesicular liposomes encapsulating biologically active substances.

Title: Plug for heat exchanger tubes
Inventor: EPSTEIN NORMAN
IPC: F16L55/11
Filed: 1988-05-06
Granted: 1993-03-02
Abstract: ABSTRACT OF THE DISCLOSURE     A tube plug for a heat exchanger tube employs a housing having a conical bore with a blind threaded cylindrical bore.  An insert member includes a threaded shank fittable into the blind threaded bore and a conical section with external threads.  An eccentric assembly at the forward end of the housing helps lock the housing against rotation as the insert member is threaded thereinto.  The threads on the conical section contact, and expand, the conical bore until an external surface of the housing is expanded into sealing contact with the surface of the conical bore.  The shape of the threads controls the local pressure exerted on the conical surface.  A piggy-back version of the tube plug employs an eccentric assembly for locking a leading tube plug in a heat exchanger tuba and a second tube plug includes a socket in its front end engageable with a nut portion on the leading tube plug.  As the second tube plug is expanded into frictional contact with the inside of the heat exchanger tube, this frictional contact adds to the torque-resisting action of the eccentric assembly and the frictional contact of the leading tube plug to permit more torque to be applied to the second tube plug without damaging the heat exchanger tube.  Additional tube plugs, identical to the second tube plug may be chained together as necessary.

Title: Apparatus and method for using a single carry chain for leading one detection and for "stickey" bit calculation
Inventor: PENG VICTOR
IPC: G06F7/485
Filed: 1988-08-24
Granted: 1991-11-19
Abstract: ABSTRACT        In a floating point addition or subtraction procedures, two shift operations of the operand fraction may be required.  The first shift operation, based on the difference between the operand exponent arguments, involves aligning one of the operand arguments so that the addition or subtraction procedure between the operand fractions can be performed.  In order to complete the associated computations correctly, it is necessary to know if any of the fraction positions removed from the fraction by the shift operation include non-zero signals, i.e., the operation referred to as computation of the "sticky" bit.  The second important shift operation occurs after the addition or subtraction of the operand fractions has taken place.  The interim resulting operand fraction must be normalized, i.e., a non-zero signal is placed in the most significant operand fraction bit position and the operand exponent argument adjusted accordingly.  In order to accomplish this normalization, the position of the leading one (most significant non-zero) bit must be identified.  The present invention utilizes a carry chain both for computing the "sticky" bit information and for detecting the leading one in an operand fraction.

Abstract: MECHANICAL DRIVE SYSTEM FOR A MEDICATION INFUSION SYSTEM  ABSTRACT OF THE DISCLOSURE    A mechanical drive system for use in driving a disposable cassette containing a reciprocating fluid pump and active valves from a main pump unit is disclosed which utilizes a single power module cam to drive both the reciprocating pump and the valves.          By using  a  unitary power module  cam,  the  system  completely eliminates  the  possibility  of  a  timing  error  between  the operation of the reciprocating pump and the valve.   A one-way clutch is used to prevent the system from slipping into a reverse operation, and the operation of the valve actuators prevents the possibility of free flow through a cassette installed onto the main pump unit.
