  • Patent number: 6368655
    Abstract: An edible anhydrous chocolate-based fat system is provided, having a significant granulated sugar component. This provides an unusual mouth sense, and allows for significantly different organoleptic properties of the chocolate-based fat system—which otherwise emulates chocolate. The chocolate may be light or dark, or white chocolate. An additional sweet flavor may be added to the chocolate-based fat system, allowing for a faster release of the additional flavor, by infusing or saturating the granulated sugar component of the fat system with the additional flavor. Typically, the granulated sugar component is saturated with an essential oil of a chosen flavor. Apart from the granulated sugar component, the remaining ingredients of the chocolate-based fat system are conched in the usual manner in keeping with chocolate production techniques. A process for production of the edible anhydrous chocolate-based fat system is discussed, and typical machinery for carrying out that process is shown.

  • Patent number: 6127962
    Abstract: There is provided an image rejection mixer for downconversion of an incoming signal to a lower intermediate frequency signal, using the absolute difference of frequencies between the incoming signal and the local oscillator signal. The image rejection mixer is set up to accept and downconvert incoming signals at two discrete frequencies f.sub.h and f.sub.l, where the local oscillator frequency is positioned mid-way between those frequencies f.sub.h and f.sub.l. There are two signal paths in the image rejection mixer, either one or the other of which is chosen by positioning a controllable single pole, double throw switch into one of its two switch positions. The output of the switch is led to a mixing element, from which an intermediate frequency signal is derived.

  • Patent number: 6116168
    Abstract: A gasifier is disclosed. The gasifier comprises a primary chamber for receiving therein biomass waste material and other related volatile solids to be gasified. A fume transfer vent permits the escape of fumes from the primary chamber. A mixing chamber accepts the fumes from the fume transfer vent. The fumes then flow to an afterburner chamber where a burner member produces a heating flame so as to cause the additional full oxidization of the constituents of the fumes so as to oxidize the constituents. A partitioning wall is disposed between the flame chamber and the primary chamber so as to preclude the heating flame from entering the primary chamber and to also preclude the radiation from the heating flame from directly entering the primary chamber, thereby precluding direct contact and physical disturbance of the waste material. A heat transfer chamber in fluid communication with the afterburner chamber accepts the fully oxidized fumes therefrom.

  • Patent number: 6092727
    Abstract: A data reading device for reading digital data encoded in one or a plurality of data-carrying surfaces directs the output from a single wavelength laser diode at the surface of the data carrier, by focusing the light from the laser using an objective lens. The data may be decoded by sensing anomalies in current flow through a precision shunt which is series connected with the laser diode, because light reflected back off the data-carrying surface is re-directed back to impinge on the laser, and the reflected light will cause anomalies in the current flowing through the diode. Alternatively, the reflected light can be deflected using a prism towards a photo-sensor. In either event, the digital data can then be decoded. A pinhole diaphragm is interposed between the laser and the objective lens, or an objective lens assembly, and the pinhole will function as a point source of light. That point source of light can be re-focused with high resolution on the data-carrying surface.

  • Patent number: 6069580
    Abstract: The present invention provides a broad band, multi-band radar detector which may be configured so as to have two or three down conversion stages. There are three mixers in the circuit, the second of which has a frequency synthesized local oscillator which is governed by a phase lock loop feedback circuit under the control of a microprocessor, so that the output frequency of the second local oscillator may be varied by an amount equal to .+-.f.sub.adj. The first local oscillator is also under the control of the microprocessor, so that a specific intermediate frequency signal from the first mixer may be derived. By varying the frequency of the second frequency synthesized local oscillator, the tuning range of the radar detector may be increased in each frequency band of interest by an amount equal to .+-.f.sub.adj for all frequency values in each respective frequency band of interest.

  • Patent number: 6065841
    Abstract: A computer monitor hood is provided having top, left side, and right side shading panels. The computer monitor hood is formed as a monolithic structure, and is made of rigid material having elastic memory. When it is first molded, the bottom edges of the left side and right side shading panels are closer together than their top edges so that, when the computer monitor hood is in place on a computer monitor, the left side and right side shading panels are biased into frictional contact with the computer monitor as a consequence of the elastic memory attempting to restore the left side and right side shading panels to their unstressed position. Thus, the computer monitor hood may be placed in any selected position on a computer monitor as a consequence of the left side and right side shading panels being biased towards and in frictional contact with the sides of the computer monitor.

  • Patent number: 5844460
    Abstract: Wound, solid state inductors are provided by winding flexible plastic tape having electrically insulative and magnetic permeability properties. Such tape is sometimes referred to as magnetic tape. An electrically conductive layer is placed on at least one surface of the magnetic tape, or both, and electrical connections are provided to the ends of the electrically conductive layer or layers. When the magnetic tape is wound into a coil, spirally or helically, and an alternating current is applied to the electrical connection, an inductive reactance will be noted. If there are two electrically conductive layers, and a voltage is applied between them, a capacitive reactance will be noted. In that case, a complex capacitive inductor element or inductive capacitor element has been configured. The wound inductors are small, light weight, inexpensive, and relatively shock proof, when compared with prior wound inductors having separate magnetic cones and wire windings placed over them.
