  • Vandal resistant display units
    Patent number: 4791746
    Abstract: A display device includes a component in the form of a plate bearing one or more display indicia on one plate surface and having a passage extending through the plate adjacent the display indicium. An integral light-transmissive element is fixedly secured in the plate passage and has a first lensed surface at one end adjacent the display indicium. At its opposite end, the light-transmissive element defines both a second lensed surface and a flat surface in abutting relation to a stepped part of the passage within the plate. The first lensed surface is convex relative to the light-transmissive element and the second lensed surface is concave relative to the light-transmissive element. The element, comprised of a polycarbonate film which is highly resistant to impact damage, is of dimension relative to the passage such that an interference-fit exists therebetween.

  • Vehicle anti-theft device
    Patent number: 4791795
    Abstract: A vehicle anti-theft device. The device is amenable for use with a vehicle having a gear lever. The device includes a removable housing which fits over and encloses the gear lever. The housing is locked in place to prevent movement of the gear lever by a bolt passing through the housing in interengagement with the gear lever and penetrating a barrel lock housing fixedly attached to the gear lever housing. The bolt has a head at one end which prevents rotation thereof, and a hole at the other end in mutual register with the bolt-engaging portion of the barrel lock. The locking of the housing in place over the gear lever prevents movement thereof so that the vehicle cannot be driven without unlocking the housing.

  • Filler collar for multiple scale weighing system
    Patent number: 4792031
    Abstract: An improved product filler collar is provided including an upper funnel portion for receiving charges of product from separate sources, guide ribs on the funnel portion for directing and controlling product flow and a neck portion for forming a single stream of product for filling a package or the like. The guide ribs may take the form of raised flanges forming a wall to confine relatively large product pieces. The flanges terminate in reduced extensions in the neck portion angled slightly back toward the product flow. The filler collar eliminates the bridging and swirling of product to prevent jams and decrease the residence time of the changes within the collar, thus improving the overall efficiency of the packaging operation.

  • Method and apparatus for manufacturing cardboard pallets
    Patent number: 4792325
    Abstract: There is disclosed a method and apparatus for continuously making cardboard runners and stringers and assembling them into a cardboard pallet. Whether a runner or stringer is involved, the method involves essentially supplying a fiberboard blank of appropriate composition and size, running the blank through a perforating and scoring roller to produce fold lines in the blank, and progressively folding the blank from the outside in, by passing it through a plurality of curvilinear rods, and applying adhesive to portions of the blank during the folding process. The runners and stringers thus produced are assembled together to form a cardboard pallet.

  • Network event identifiers
    Patent number: 4792921
    Abstract: Identifiers for events occurring at a network node are generated responsive to the time of the event, to a telephone number associated with the node, and to an event characteristic. In a network all of whose nodes use this method, an identifier can be generated at one node without reference to any other node, which will be unique over the network. An identifier generated by this method can be decomposed to recover the time of the event, the telephone number associated with the node at which the event occurred at the time of occurrence, or the event characteristic.

  • Coffee brewer
    Patent number: 4791859
    Abstract: A beverage brewing machine which has upper and lower brewing chambers which are movable relative to each other so as to clamp a strip-shaped filter therebetween during the brewing process and the chambers can be separated so as to allow the filter strip to be removed from the brewing chamber and the beverage residual wiped therefrom after which the filter strip is returned to the brewing chambers which are then resealed for the next cycle. A hold down grid engages the top surface of the filter to hold down as a piston moves in the lower chamber upwardly to force air through the filter to agitate the beverage. When the piston reaches top dead center, the hold down grid is lifted. When the piston passes the opening the brewed coffee is poured.

  • Antenna coupling amplifier and converter system
    Patent number: 4792987
    Abstract: An antenna coupling system includes separate low-noise receiving amplifier and down converter circuits for amplifying the antenna signal above background noise and for converting it down to frequencies compatible with a suitable receiver, respectively. The system is particularly intended for microwave frequency antennas of the type used to receive satellite signals. The amplifier circuit includes at least one microwave frequency amplifier, such as a GaAs FET, with a low frequency variable feedback circuit connected across it which is arranged to self-tune the amplifier to the antenna input signal strength. The converter circuit is of the image reject single conversion and image recovery type and is arranged to split the amplifier output signal into two parts which are each combined with a local oscillator signal and then re-combined in such a way that unwanted image signals are rejected.

  • Flow monitoring
    Patent number: 4791810
    Abstract: An apparatus and a method are provided for detecting and monitoring flow of a fluid through an injector, such as a fuel injector (10) of a diesel engine. Ultrasonic waves are detected by a transducer (12), and signals passed through a filter (20), so as to observe broadband signals of frequency above 100 kHz. Such signals are due to turbulent flow through the injector orifice (38), and so enable the flow itself to be detected.

  • FM receiver having improved audio quality in response to Rayleigh faded received signals
    Patent number: 4792991
    Abstract: The present invention minimizes noise pops due to Rayleigh fades by controlling receiver gain relative to the average received signal strength so that only a predetermined level of limiting occurs prior to the recovery of the audio information. The amount of limiting is selected so that a significant Rayleigh fade will cause the amplified IF signal to drop below the limiting level and enter the linear amplification region. During the fade the magnitude of the signal provided to the discriminator decreases thereby decreasing the discriminator's output and minimizing the magnitude of the audio pop. Additional minimization of the subject noise pops is achieved by utilizing a discriminator which has a square law transfer characteristic so that the recovered audio level will decrease 2 dB for every 1 dB decrease in input signal level.
