Filed: 1991-09-13
Abstract: ABSTRACT OF THE DISCLOSURE      A tube connector for sealing a flareless tube to a fitting having a flat sealing face perpendicular to the fitting axis.  The tube connector incorporates a ferrule engaged by a sleeve mounted on the end of the tube and having a flat radial surface for engaging the fitting sealing face.  The ferrule is deformable and establishes a primary wedge type metal-to-metal sealing engagement with the tube by a compression nut threaded upon the fitting.          The  ferrule  radially  bows  under  axial  and radial compression and this deformation suppresses vibration while the shape of the ferrule end engaged by the nut increases the radial forces on the ferrule as the nut is tightened to provide firm tube support remote from the seal region.          The sleeve is provided with an internal undercut adapted to outwardly flare the end of the tube to lock the tube to the sleeve, and radially support the tuba end as the tube is compressed during connection.

Filed: 1992-02-25
Abstract: A device for maintaining docks or other floating bodies at a given distance from and orientation to the shore by means of a ratchet assembly hinged on the side of the dock closest to shore, and a line attached to two guides, such as pulleys, on the underside of the dock.  When the level of the water varies, the device maintains the dock at the same distance from the new waterline as it was from the old, in the following manner:  the line is anchored at one end on shore and at the other to a bottom anchor beyond the farthest point the dock will extend to at lowest water level.  Tension in the line pushes the dock towards the shore until the ratchet contacts the bottom, where equilibrium is established.  If the water falls, the ratchet pushes the dock away from shore and a new equilibrium is established, farther out; this repeats as long as the water falls.  If the level rises, the ratchet is raised off the bottom and the dock moves towards shore to a new equilibrium point.          This continues as long as the water rises.  Guides are configured so as to minimize rotational movement.

Title: Bispecific reagents for aids therapy
Inventor: FANGER MICHAEL W
IPC: C07K16/46
Filed: 1990-06-29
Abstract: Bispecific molecules which react both with the high-affinity Fc.gamma. receptor of human effector cells and with a virus or virus component are disclosed. Binding of the molecules to the Fc receptors found on effector cells is not blocked by human immunoglobulin G. The molecules are useful for targeting human effector cells (e.g. macrophages) against a viral target (e.g. HIV or HIV-infected cell). For this purpose, bispecific molecules can be constructed containing the binding region derived from an anti-Fc.gamma.  receptor antibody and the CD4 molecule or CD4 binding domain of the envelope glycoprotein gp120 of HIV. Alternatively, bispecific antibodies or heteroantibodies can be constructed containing the binding region derived from an anti-Fc receptor antibody and the binding region of a HIV-specific antibody such as anti-gp120 antibody. Targeted effector cells can be used to kill virus by cell mediated antibody dependent cytolysis.

Title: Enhanced reliability in portable rechargeable devices
Inventor: AEBI TONI
IPC: G07B17/00
Filed: 1992-06-26
Abstract: A2??68 - 1340/17014 ABSTRACT OF THE DISCLOSURE         In a postage meter which has a meter section powered by house current in normal operation, but which requires auxiliary power source batteries while in transit, a circuit is provided which, in connection with a stored program, tests the auxiliary power source prior to the period away from the house current power, thus providing a warning if the auxiliary power is unlikely to sustain the device for the duration of the period away from house current power.  The test circuit applies a test load approximating the load of the meter section to be powered.          A loop in the program of a CPU determines the period of time during which the test load is applied to the batteries and then a voltage comparator assures that the battery output voltage is sufficiently high in the range of usable voltage therefrom to assure successful operation of the postage meter section during resetting at the post office.  A post office switch for use by a postal worker can be closed only when a postal worker unlocks an associated lock.  This delivers auxiliary power from the batteries to the meter electronics including the CPU.  A routine detects this and causes the CPU to provide a output to a switching transistor that continues to supply the auxiliary power for the brief interval necessary for resetting.
