Abstract: ABSTRACT   An improved pyroelectric sensing apparatus for use in applications such as microwave ovens, where it is necessary to sense the presence of steam generated by a food item being heated and to generate a load-stop signal which shuts down the heating mechanism at the appropriate time.  The apparatus comprises a pyroelectric element which issues a succession of pulses upon contact by steam on its sensing surface, detection means for detecting pulses of above a predetermined level by sampling with predetermined sampling timings, succession period detection means for detecting the time period of the succession of pulses, and comparison means for comparing the time period detected by the succession period detection means with a predetermined reference time period and issuing a control output signal when the detected time period is longer than the reference time period.  The pyroelectric sensing apparatus in accordance with the present invention can make accurate and reliable signal detection because of its high S/N ratio, since noise output spikes caused by mechanical shock or electric shock are prevented from producing the load-stop signal, by taking advantage of the characteristic of the pyroelectric detection signal caused by boiling steam having low frequency components.

Abstract: METHOD AND MEANS FOR DETERMINING AIR MASS IN   A CRANKCASE SCAVENGED TWO-STROKE ENGINE          Abstract of the Disclosure A method and means are described for determining the mass of air available for combustion within a cylinder of a crankcase scavenged two-cycle engine, without the use of a mass-air flow sensor This is achieved by estimating the mass of air under compression within a crankcase chamber, prior to its transfer to a cylinder combustion chamber during the engine operating cycle.   The estimate for air mass is based upon the polytropic behavior of a portion of the crankcase compression process, and the pressure, volume and temperature of the air at two predetermined engine rotational positions during the polytropic phase of compression.   The volume of the air within the crankcase chamber is determined as a function of engine rotational angle, with crankcase air temperature being derived as a function of intake air temperature.   Air pressure during the polytropic phase of compression is sensed with a pressure sensor disposed within the crankcase chamber.   The estimate for air mass is corrected to account for air leakage and imperfect transference of the air between the crankcase and combustion chambers.

Granted: 2000-12-19
Abstract: Method and apparatus which utilize an LCD modulator array for printing and/or enlarging an image recorded in a color film negative, a positive transparency or a color print, which LCD modulator array has pixels whose "closing time" (the time it takes to convert a pixel from a condition wherein it transmits radiation to a condition wherein it blocks radiation) is substantially longer than their "opening time" (the time it takes to convert a pixel from a condition wherein it blocks radiation to a condition wherein it transmits radiation). In accordance with the present invention, each pixel of the LCD modulator array is opened and closed in a rapid sequence, one after the other, at intervals which are much shorter than the closing time of the pixels of the LCD modulator array. The amount of radiation transmitted by each rapidly opened pixel is determined by detecting a spike of radiation which is transmitted through the rapidly opened pixel and by detecting and subtracting a background amount produced by radiation which is transmitted through other, slowly closing pixels.

Title: Metallocene catalysts for polymerization of olefins
Inventor: ELDER MICHAEL J
IPC: C08F4/76
Filed: 1990-10-09
Granted: 2001-09-04
Abstract: This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an active proton and contains a carbonium, oxonium or sulfonium cation. The anion of the ionizing ionic compound is not coordinated or is only loosely coordinated to the metallocene cation and is chemically unreactive with the metallocene cation.   One such compound is triphenylcarbenium tetrakis(pentafluorophenyl)boronate.     The process of making catalysts with this invention produces catalysts having high activity and does not produce by-products which can inhibit catalyst activity.      This new synthesis is a clean reaction which does not produce a Lewis base. The process generates active catalysts by removing a methyl anion from a group IV metallocene derivative.
