  • Publication number: 20130286482
    Abstract: A temporary, moveable marker for directing emergency aircraft to a landing zone employs a set of four panels which are foldable into a compact configuration. These panels are deployed in a substantially rectangular configuration to provide markings for an emergency landing zone and are attached by three hinges. This creates two panels with hinges on the two interior sides of the respective rectangles and two panels, each with one hinge on one interior side. All panels have aligning apertures so that the panels can be collapsed on top of each other to form one rectangle with an aperture through which a screw can be placed and affixed with a wing-nut on the other end, thus keeping the four panels attached. The collapsed set of four panels lie flat with at least one handle on an exterior side to allow for easy storage and transportation.

  • Patent number: 6837404
    Abstract: A system utilizing a flaccid tube for delivery of liquids with a spray container is disclosed. This device can be substituted for the usual straight, non-flaccid tubing widely used with liquid dispensing containers. The system consists of a flexible tube and a weight attached to the end which causes the tube to seek the liquid, regardless of bottle or vessel position. The weight is attached to the tubing by a bushing or sleeve which inserts into the distal end of the flexible tube, compressing the tube walls outward resulting in a secure and tight attachment of the weight. The system allows the user to easily spray, squirt or expel liquids from any orientation which includes complete inversion of the container. The weight design components are inexpensive to manufacture, and can be easily attached to an existing spray bottle, and can thus be used, transferred, and re-used multiple times thus conserving resources.

  • Patent number: 5817381
    Abstract: A process and materials are described in which highly refined celleuloise fibers are broken down into microfibers and further processed into compositions, films. coatings and solid materials which are biodegradable and even edible. The process for the formation of hardenable compositions may comprise:providing a composition comprising non-wood cellulose fiber, 36. mechanically reducing the size of the non-wood cellulose fiber to less than 2 mm, reducing the amount of binding of microfibers by lignin within said non-wood cellulose fibers present in said composition comprising cellulose fiber to form a first fiber product, providing pressure of at least 300 psi to said first fiber product while it is in the presence of a liquid, and removing said pressure within a time interval which will cause said cellulose fiber to break down into a second fiber product comprising microfibers in said liquid.

  • Patent number: 4800341
    Abstract: A synthesizer produces step frequencies by multiplying the frequency of a reference oscillator and stimulating an SRD comb frequency generator, then adding or subtracting a reference frequency. The selected step frequency can be placed on either side of each picket of the comb's spectrum. A fine adjustment frequency is then added in a translation oscillator. The fine frequency component can also be placed on either side of the selected step frequency.Frequency dividers, which would result in noisy final outputs, are not employed. Instead, the frequency of a reference signal is multiplied up in a narrowband channel to serve as a local oscillator, and the VCO signal frequency is reduced by heterodyning it down from its ultra-high frequency. The down-converted difference frequency is compared as to phase with the reference oscillator. The loop gain and bandwidth are so high in the phase lock loops that output noise is low and switching time is fast.

  • Patent number: 4048567
    Abstract: Narrow amplitude calibrated pulses are injected into the RF input ports of microwave receivers such as those used for interference and intensity measurements to gain calibrate the receivers. The upper frequency limit of the prior art calibration source is greatly extended by frequency modulating the pulse generator to obtain pulses that vary in repetition rate between 95 and 105 MHz so that beginning with the tenth harmonic, a continuous band of pulses of predetermined amplitude sweeps from 950 MHz up to approximately 18 GHz.

  • Patent number: 4031469
    Abstract: Receivers with bilateral input stages, such as microwave receivers that are used in noise and RF interference measuring instruments, are gain calibrated in the field by injecting a fixed level calibration signal at the IF frequency into the circuitry between the first mixer and first IF stage. The calibration signal is thus passed through the first mixer where it is converted to the tuned RF frequency and then to the RF input port where its power is measured to control a variable attenuator in series between the calibration signal source and the receiver IF stages. The attenuator is thus automatically adjusted so that the level of the calibration signal entering the IF stage balances the losses in the receiver front end, and a variable gain IF amplifier may be adjusted to produce a predetermined level on the receiver output meter to properly calibrate the instrument.

  • Patent number: 3965431
    Abstract: Circuitry for generating pulses with extremely accurate widths. Clock signals, from a precision crystal controlled oscillator, control an input flip-flop which fires a one-shot multivibrator adjusted as closely as possible to the desired pulse width. The one-shot output is coupled to an output flip-flop controlled by the crystal controlled clock so that the width of the output pulse becomes an exact multiple of the clock period.
