Title: Sequentially injected multi-component injection molding
Inventor: SORENSEN JENS OLE
IPC: B29C45/26
Filed: 1990-08-13
Granted: 2000-11-07
Abstract: A highly efficient and highly controllable method and an apparatus for core-back injection molding of multi-component plastic products. Core-back injection molding makes possible the injection of a first plastic material into a mold cavity followed by retracting a barrier means (22, 26) in order to enable injection of a second plastic material without separating any mold halves. The present invention enables very efficient injection molding because both injection units may be operated at the same time, and the present invention enables very controlled injection because it is possible to inject only one half of the cavities by a specific injection unit at the same time, or even only one quarter of the cavities by a specific injection unit at the same time. The injection molding apparatus includes a first injection unit, a second injection unit, a right adjustable mold cavity (20) with a first moveable barring means (22), a left adjustable meld cavity (24) with a second moveable barring means (26), and a common standard clamping unit (28).

Title: Arginine antagonists for inhibition of systemic hypotension associated with nitric oxide production or endothelial derived relaxing factor
Inventor: KILBOURN ROBERT G
IPC: A61K31/00
Filed: 1990-09-13
Granted: 2001-07-17
Abstract: A method for prophylaxis or treatment of an animal for systemic hypotension induced by internal nitrogen oxide produc-tion. The method involves administering a therapeutically effective amount of certain arginine derivatives to inhibit nitrogen ox-ide formation from arginine. Preferably N G-substituted arginine or an NG,NG-disubstituted arginine (having at least one hy-drogen on a terminal guanidino amino group replaced by another atomic species) is administered to an animal possibly developing or already having such induced systemic hypotension. The arginine derivatives are preferably of the L configura-tion and include pharmaceutically acceptable addition salts. Prophylaxis or treatment of systemic hypotension in a patient which has been induced by chemotherapeutic treatment with biologic response modifiers such as tumor necrosis factor or interleukin-2 may be accomplished. Treatment of an animal for systemic hypotension induced by endotoxin, i.e., septic shock may also be accomplished by treatment with the arginine derivatives.

Title: Locking arrangement for disconnect switch
Inventor: RAMOS JOEL A
IPC: H01H9/28
Filed: 1992-04-13
Granted: 2002-07-02
Abstract: An arrangement for locking the disconnect linkage of a high-voltage switch is provided that includes two relatively movable locking members that are each moved between locked and unlocked positions in response to operation of the disconnect linkage. As the disconnect linkage is moved to an opened position, the two locking members are moved into relative overlapping alignment to receive a blocking member to prevent movement of the disconnect linkage. One locking member is carried by the disconnect linkage and the second member is carried by a pivotally mounted support arm that is affixed to the disconnect linkage so as to move therewith. Accordingly, the second locking member does not encroach on the space adjacent the disconnect linkage except when it is moved into alignment in the opened position. The support arm that carries the second locking member is arranged to guide the disconnect linkage and prevents undesirable movement of the disconnect linkage due to transverse forces on the disconnect linkage during movement between the opened and closed positions.

Title: Filterbank using surface acoustic wave technology
Inventor: PEACH ROBERT C
IPC: H03H9/02
Filed: 1992-05-25
Granted: 1995-12-05
Abstract: A filterbank using surface acoustic wave technology and has a plurality of filters.  Each filter has an input transducer and an output transducer.  The input transducers are connected in parallel to a single matching circuit.  The output transducers each have a separate matching circuit. The transducers are formed by a thin film of aluminum pattern on a piezoelectric substrate. The input transducers all have the same structure and the output transducers all have the same structure, though that structure is different from the input transducers. The only difference between the transducers of each filter is the location of electrode breaks for each electrode.  A weighting function of the transducers is scaled and biased to provide a constant impedance across the bandwidth of the filterbank and to equalize the output amplitudes and capacitances of the output transducers.  This produces a continuous level response across the bandwidth of the filterbank. Previously, while a continuous level response was theoretically achievable, it cannot be achieved in practice.
