Abstract: A heating apparatus for a vehicle includes a heat exchanger for implementing heat exchange between coolant which has cooled an engine and air directed to a vehicle interior to heat the vehicle interior. A viscous heater has a rotor and a heating chamber containing viscous fluid. The rotor rotates when being subjected to rotational power of the engine. The viscous fluid is subjected to a shear force and is heated when the rotor is subjected to the rotational power. The viscous heater heats the coolant fed to the heat exchanger as the viscous fluid in the heating chamber is heated. A clutch is operative for selectively permitting and inhibiting transmission of the rotational power from the engine to the rotor. A belt transmission device connects the engine and the clutch. A physical quantity detecting device is operative for detecting a physical quantity related to a rotational speed of the rotor. A control device is operative for controlling the clutch to inhibit the transmission of the rotational power from the engine to the rotor when the physical quantity detected by the physical quantity detecting device is equal to or less than a predetermined value.

Abstract: On décrit un procédé d'extrusion en continu d'articles en matières plastiques orientées, lesquels présentent une résistance améliorée. On ajoute un polymère (33a, 33b), monomère ou autre composé chimiquement réactif dans le(s) matériau(x) matriciels et on extrude ou on forme par fusion une paraison (34) (multicouche) présentant une orientation thermoplastique interne provoquée par cisaillement ou par écoulement avec allongement. On peut activer une réaction dans la paraison à l'état fondu, à l'aide d'une chaleur supplémentaire, afin d'obtenir une structure réticulée ou au moins une réduction de la mobilité des molécules, avec pour conséquence un temps de relaxation plus long, permettant le figeage de l'orientation permanente. On peut étirer la matrice amollie, lorsqu'elle est encore chaude, dans une direction circonférentielle et/ou axiale. Ensuite, on calibre le produit ainsi obtenu et on le refroidit dans un état orienté.

Title: Transistor-based apparatus and method for molecular detection and field enhancement
Inventor: SHIEH CHAN-LONG
IPC: C12Q1/68
Filed: 1997-08-07
Granted: 2002-11-05
Abstract: Binding of a molecule (24) to a molecular receptor (22) is sensed using a transistor (10) having a gate (14) located at a binding site. The channel (20) conductance of the transistor (10) is modified by a charge associated with the molecule (24) when the molecule (24) binds with the molecular receptor (22). A  modified electrical characteristic of the transistor (10) which results is sensed to sense the binding event. Electric field enhancement is provided by applying a voltage to the gate (14). A second sensing transistor can be coupled to the sensing transistor to form a differential pair. The differential pair allows for enhancing and sensing of differential binding events.

Abstract: A loader linkage having a bucket and boom arm mounted to the loader vehicle by way of top and bottom links, the top link being pivotally coupled with a structural member of the vehicle that extends upwardly from the vehicle frame generally at the rear of or behind the operator station. The top link is coupled to the structural member at a point generally above and behind the operator seated on the vehicle. The linkage establishes a bucket path that extends generally vertically initially and that then extends forwardly through the entire range of upper motion of the bucket. The linkage causes the bucket to achieve maximum reach at the bucket's maximum height. The orientation of the top link also reduces the vehicles tendency to tilt rearwardly onto the rear wheel's during leveling operations.

Abstract: Paper mill cores of the invention are structured to allow winding and unwinding chucks to distort the interior diameter and shape of the interior body wall of the core while resisting distortion of the core exterior to prevent center burst failure. The paper mill cores of the invention include a multi-ply zone of high strength, but relatively compliant, paperboard plies within the outer 70%  (based on the total body wall thickness) of the body wall having a thickness of at least about 4 mm. An interior zone constituting at least about 25% of the total thickness of the body wall is formed from extremely high strength, extremely high density paperboard plies. The overall wall thickness of the core is preferably at least about 15 mm, and is thus preferably increased, as compared to the wall thickness of conventional high strength wide paper mill cores formed entirely of extremely high strength, extremely high density, non-compliant paperboard plies.
