Title: Inertial welded cylinder and method of making same
Inventor: FULLER DENNIS A
IPC: B23K20/12
Filed: 1992-11-18
Granted: 2004-02-24
Abstract: A friction or inertial welded cylinder is made of a tube and base member. The base member has an annular groove that is positioned within the cylinder tube and which receives the kerf formed on the interior of the cylinder during welding. The groove height is formed to provide a place to receive the kerf as it curls and to seal material within the groove so foreign materials do not later break loose from the kerf and cause damage to the cylinder assembly in use.

Title: Method of gene transfer using galactosylated histones
Inventor: CHEN JIAN
IPC: C12N15/87
Filed: 1993-02-25
Granted: 1997-04-08
Abstract: The present invention relates to the field of introducing genetic material to cultured cells and into cells of animals in vivo. In particular, the invention relates to the use of receptor-targeted neoglycoprotein to carry genetic material into cells. The invention also uses nuclear-localization signals(Gerace et al. Annu. Rev. Cell Biol. 1988, 4:335-374), to facilitate the entry of genetic materials into cell nucleus for gene expression. The present invention has a wide variety of applications, for example, in treatment of genetic diseases, in study of cell biology, and in genetic interventions of physiological and pathological processes. The present invention is a effective method for introducing and expressing genes in hepatoma cells and hepatocytes in vivo. Its design has several novel features. First, this invention uses a simple coupling reagent (1-ethyl-3-(3-dimethylaminopropyl) carbodiimide) to chemically add galactose to a protein, histone, in a one step reaction. The galactosylated protein (for example, albumin, histone and any other protein) has high affinity for the ASGP receptor; Second, the invention uses a protein which is a natural DNA-binding protein; Three, this invention uses a protein which crosses the membranes of cell nucleus by a facilitated process in addition to simple diffusion. This feature contributes greatly to the high level expression of the introduced foreign genes; Last, the galactosylated histone 1 is the physical embodiment of all the features in this invention. This means this gene delivery system has only one component and is simple, reliable, and efficient from engineering-design point of view.

Granted: 2001-03-06
Abstract: Apparatus and methods used in a network for translating names into network addresses. Source nodes in the network receive names and have name caches for translating the names; destination nodes have have local name tables containing correspondences between names and the network addresses served by the destination node. There is further a name server accessible to the nodes which contains current correspondences between names and network addresses. A name is translated by first presenting it to the name cache in a source node; if there is no entry for the name in the cache, name cache maintenance code in the source node obtains information about the name from the name server; once there is an entry, the name is translated and a call set up message containing the name and the network address is sent to the destination node, which checks whether the name and network address are its local name table. If they are, the destination node returns a call complete message to the source node. Otherwise, it returns an unknown destination message to the source node. The name cache maintenance code responds to the unknown destination message by invalidating the cache entry and obtaining the correct information from the name server.

Abstract: A control system (104)/method for semi-automatically executing automatically and manually selected upshifts and downshifts of a mechanical transmission system (10) is provided. The control system includes a central processing unit (106) for receiving input signals indicative of transmission input shaft (16) and output shaft (90) speeds and from a driver control console (108) and processing the same in accordance with predetermined logic rules to issue command output signals to a transmission actuator (112, 70, 96) to implement the selected shifts.  The control is effective to initiate a shift by automatically preselecting a shift from the currently ratio into neutral and to then await a manually caused torque break of the transmission to complete the shift to neutral. The control is effective to minimize wear by issuing repetitive shift prompts if transmission neutral is not sensed within predetermined times from preselection of a shift from a currently engaged ratio (GR) into neutral (N).

Abstract: A throttle valve is provided in each actuator of a calender roll controller with the throttle valve controlling an internal air orifice within each actuator to provide a substantially uniform air mass flow of either hot or cold air.  Each throttle valve is controlled in response to the temperature of the air being delivered by the actuator such that a smaller orifice is provided for hot air than for cold air to provide substantially uniform air mass flow from each of the actuators and therefore substantially uniform air velocity to better control the temperatures of the longitudinal zones of a calender roll and better maintain boundaries between the zones.  In addition to throttle valve control of the actuators, an air scoop concentric with a calender roll being controlled and spaced from the calender roll is provided to channel air from the actuators over the calender roll.  The scoop comprises heat insulating material to prevent heat loss out the back of the scoop.  In addition, a plurality of arcuate zone strips are provided on the concave inner surface of the scoop and in substantial alignment with the plurality of actuators for channeling air from the actuators. The arcuate zone strips are spaced apart from one another for thermal separation such that thermal diffusion among longitudinal zones of a calender roll within the scoop are substantially eliminated.

Abstract: A slack adjuster for use in combination with a pneumatic brake actuator cylinder wherein the slack adjuster includes a friction clutch which prevents rotation of the screw for first relative position of the piston and screw while allowing rotation of the screw for excess force on the ram pulling the screw to a relative position beyond the first relative position and opposite the relative position for normal slack adjustment in response to air actuation of the piston. A second clutch, which is a standard toothed clutch, prevents rotation of the screw for second relative position of the piston and the screw.   The screw rotates  between  the  first  and  second  relative positions when  the two  clutches  are unlocked  to produce slack adjustment.  The pulling force on the slack adjuster is produced by a hand brake on the output of the slack adjuster and independent of the piston.
