Abstract: ABSTRACT A method of manufacturing electrodes for a spark plug (82) whereby a set gap "g" between the tip (12) of a center electrode (80) and a side electrode (62) is substantially uneffected by the exposure to combustive gases in an engine.  The center 34 of the tip of the center electrode (80) and center of the side wire (62) are located by a mark.  A first sphere (36) of platinum is placed in a fixture and the center (34) on the tip of the center electrode (80) aligned over the first sphere (36).  Pressure is applied to the center electrode (80) while electrical current is applied thereto.  Thermal energy created at the junction of the axial center (34) and first sphere (36) causes the inconel material in the center electrode (80) to flow and surround the sphere of platinum (36).  The side electrode (62) is attached to the metal shell (60)and a second sphere (36') of platinum is similarly metalurgically bonded thereto.  The center electrode (80) is placed in a ceramic insulator (30) and retained in a metal shell (60).  A gap "g" is thereafter established between surfaces (46 and 72) of the first and second platinum spheres (36, 36').  The fixed gap "g" is maintained for the life of the spark plug (82) since the first and second platinum spheres (36, 36') are substantially uneffected by combustive gases in an engine.

Abstract: ABSTRACT      A system of arbitration for access to a common memory by two asynchronous microprocessors without excluding either microprocessor for more than a predetermined, limited period of time.   Two asynchronous microprocessors are connected to a common memory through an arbitration controller with a connection to transmit a "not ready" signal to one microprocessor requesting access when the other is in the process of accessing the common memory.   A flip flop is connected to generate a predetermined signal output when a microprocessor requires access to the common memory, and this predetermined signal initiates a shift register to provide the internal timing of the asynchronous microprocessor requiring such access to bring it into synchronism with the clock controlling the internal cycle of the common memory.   When there is contention for access to the common memory, a flip flop connects one microprocessor to the common memory, where such connection is maintained only for a predetermined, limited period of time, when access is returned to the first microprocessor.   Access to the common memory by any microprocessor is always for only this one, predetermined, limited period of time.

Abstract: In the preparation of a supported procatalyst intended for the polymerization of olefins, particles are formed of magnesium dihalide and alcohol. The particles are reacted with an organic compound of a metal from the groups I-III, and the resulting particulate product is activated by means of a titanium and/or vanadium compound and optionally a donor, and optionally a prepolymerization is carried out for the activated particles. A problem of such a method is how to form particles of magnesium dihalogenide and alcohol having a structure advantageous for the polymerization of olefins. The problem has in the present invention been solved so that the particles are formed by spray crystallizing (spray freezing) a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol. The hydroxyl content of the particles so obtained is much greater than earlier, which results in a much more active procatalyst than the preceding ones.

Abstract: An accelerometer arrangement includes an acceleration sensor that includes two capacitor plates having respective parallel mutually facing major surfaces which bound a sensing gap therebetween. A plate-shaped electrically chargeable proof mass is resiliently mounted in the gap in parallelism with the major surfaces for displacement in response to the action of acceleration forces thereon out of a substantially central rest position toward one or the other of the major surfaces depending on the direction of the acceleration forces.  An electrical potential difference is established between the capacitor plates to generate respective electrostatic fields between the capacitor plates and the proof mass which cause a proof mass electrical potential variation having a magnitude and sense depending on the extent and direction of the displacement of the proof mass out of its rest position.  The variation is evaluated and an a pulse train that is proportionate to the variation is generated and supplied to the proof mass to establish thereat a voltage sufficient for electrostatic forces caused thereby between the proof mass and the capacitor plates to return the proof mass to the rest position thereof against the action of the acceleration forces on the proof mass.

Granted: 2000-03-14
Abstract: Stable, clear, antimicrobially effective, ophthalmic formulations are disclosed which provide an antimicrobially effective preservative. The formulations include an ophthalmologically effective amount of a drug, which is a -COON group-containing non-steroidal anti-inflammatory drug (NSAID) in combination with an antibiotic drug, and a preservative system formed of a quaternary ammonium preservative and a nonionic polyoxyethylated octylphenol surfactant, all in an aqueous vehicle. The preservative system can be used with other formulations which require the preservative to be ophthamologically acceptable and antimicrobially effective. These formulations are useful for treating diseases and/or conditions that are either caused by, associated with or accompanied by inflammatory processes, including, among others, glaucoma, cystoid macular edema, uveitis, diabetic retinopathy and conjunctivitis, or any trauma caused by eye surgery or eye injury. The ophthalmologically acceptable antibiotic is preferably tobramycin which has been found not to interfere with the rate of diffusion of the NSAID. The combination of the NSAID and antibiotic is particularly effective in simultaneously preventing and/or eliminating infection while preventing and/or eliminating inflammation.
