Patent CA-2233421-C (CA)
Title: Improved plastic articles and processes
Inventor: VAUGHN MICHAEL L
IPC: B29C49/02
Filed: 1998-03-26
Granted: 2006-01-31
Abstract: Improved processes for making plastic articles, such as carbonated beverage bottles made from PET, are disclosed. The process includes the step of molding a preform which comprises thermoplastic resin and glass pellets that are substantially uniformly dispersed in the resin. By including the glass pellets, the preform can be more easily and efficiently reheated, if necessary during production. Because the glass pellets are retained in a substantially uniform dispersion in the blown article, the article is not subject to electrostatic adhesion to other articles following release from the blow mold.

Abstract: Method and apparatus for forming hollow tubular light-distributing tubes for area illumination along the length of the tubes from a beam of light introduced into one end.  Within the tube is a geometrically complex, 3-dimensional light redirecting structure traversing the light beam along the full length of the tube to redirect the light beam proportionately along the length of tube through a window formed therein.  Both the tube and the light-redirecting structure can be formed as an integrated flat, substantially  void-free  structure  for  shipping  and  then converted in situ to the operative, 3 dimensional configuration.

Abstract: The present invention relates to transgenic non-human animals that are engineered to contain human immunoglobulin gene loci. In particular, animals in accordance with the invention possess human Ig loci that include plural variable (VH and V) gene regions. Advantageously, the inclusion of plural variable region genes enhances the specificity and diversity of human antibodies produced by the animal. Further, the inclusion of such regions enhances and reconstitutes B-cell development to the animals, such that the animals possess abundant mature B-cells secreting extremely high affinity antibodies.

Abstract: In an occupant restraint apparatus for installation in a vehicle, a smart airbag inflator (14) is provided with a piston (30) for regeneratively pumping liquid propellant from a reservoir (49) into a combustion chamber (48) for ignition and combustion to generate airbag inflation gases. To control the airbag inflation rate, the piston includes a piston head (32) slidingly received in a damping chamber (46) filled with a magneto-rheological fluid (83) that is pumped through an orifice (92) during the regenerative pumping stroke of the piston. An electromagnet (86) is selectively energized to produce a varying magnetic field to adjust the viscosity of the magneto-rheological fluid flowing through the orifice and thus vary a damping force exerted on the piston stroke, thereby modulating the rate of liquid propellant combustion. Electromagnet current excitation is controlled in response to a particular accident scenario.

Title: Distributed gain line driver amplifier
Inventor: SHULMAN DIMA DAVID
IPC: H03F3/72
Filed: 2000-04-19
Granted: 2002-08-20
Abstract: A line driver amplifier is implemented by employing amplifier stages including a plurality of output transistors and a corresponding plurality of auxiliary amplifiers. The output transistor and auxiliary amplifier pairs are connected in parallel.  Each of the auxiliary amplifiers includes a built in voltage offset, beginning with an auxiliary amplifier having the smallest voltage offset to the auxiliary amplifier having the largest offset. The individual auxiliary amplifiers maintain their corresponding output transistors in an OFF state so long as the overall amplifier input signal has a magnitude less than the auxiliary amplifier offset voltage level. When the input signal magnitude level is equal to or greater than the offset voltage level of an auxiliary amplifier, that auxiliary amplifier turns its corresponding output transistor to an ON state.  Thus, for lower magnitude input signals fewer than all of the output transistors are in an ON state, while for maximum magnitude input signals all of the output transistors are in an ON state. Use of the auxiliary amplifier-output transistor pairs allows use of smaller size transistors, each of which has a lower output current than an equivalent single output transistor. Since all of the output transistors in each amplifier stage are connected in parallel, the amplifier output current is the sum of the currents passing through the ON output transistors. Consequently, the linearity of the overall amplifier structure is significantly improved in the frequency domain. In one embodiment of the invention the auxiliary amplifier offset voltage levels are fixed, while in another embodiment of the invention the offset voltage levels of the auxiliary amplifiers are adjustable, e.g., programmable.
