  • REMOVABLE CORNER GUARD FOR CONTROL TABLES OR TOOL BOXES
    Publication number: 20150076305
    Abstract: A removable corner guard is provided. The removable corner guard is especially suitable for protecting the corners of, for example, control tables or tool boxes from deformations and from scratches. Further, the corner guard may be used as decorative addition to an otherwise plain control table or tool box. The device has a semi-rigid rubber housing which covers securing anchors having an internal skeleton. An extended ridge on a lower end of the corner guard locks the corner guard at the lower end of the edge of the control table. The corner guard may be adjusted to fit control tables or tool boxes of various sizes. A non-slip textured exterior surface may allow for the device to be easily transported.

  • PASSIVE, METAL MOUNT, UHF, RFID TAG CAPABLE OF A LONG READ RANGE
    Publication number: 20150108300
    Abstract: A passive, metal mount, UHF RFID tag with a high antenna efficiency is provided. The passive, metal mount, UHF RFID tag has a first securing surface and second securing surface which are both hinged at sides of a main body of the tag and which allow the tag to be secured to flat objects, round objects having various circumferences or to objects having unusual exterior surfaces. A pressure sensitive adhesive (PSA) tape secures the tag to the object. The tag allows the main body (or “form factor”) to be offset from a metallic asset which is tracked without the metallic object negatively interfering with the RFID. The metallic surface of the asset being tracked is used to activate the Patch antenna duality of the custom design inlay, thus increasing the radiation efficiency of the driven element (integrated circuit) and ultimately the read range.

    Patent number: 9373893
    Abstract: An RFID tag and a method for optimizing a Yagi-Uda antenna for a RFID inlay or integrated circuit is provided. The method has steps comprise: 1) selecting an electrically conductively first element; 2) generating an electrically conductive second element by taking a mirror image of the electrically conductive first element and trimming the second element; 3) generating a third element” along a line of axis of symmetry of the first two elements and on the opposite side of the first element as the electrically conductive second element; 4) adjusting the distance between the first three elements for optimum performance using Et(x)=EXP[a?x·b]+E?; and 5) optionally, if the electrically conductive first element does not contain an IC (integrated circuit) or RFID inlay, then adding an IC or RFID inlay adjacent to/or physically touching the electrically conductive first element along the line of symmetry.

  • Method and apparatus for making fragmentary ice
    Patent number: 4646526
    Abstract: Fragmentary water ice is produced in an enclosure by metering water into a flowing body of liquid refrigerant having a greater density than the water or ice, lifting the ice out of the refrigerant and through a zone of further cooling in which the adhering liquid refrigerant, itself, is cooled and drained from the ice, and discharging the ice through an opening in the enclosure.

  • Variable volume ratio screw compressor with step control
    Patent number: 4678406
    Abstract: An axial flow helical screw compressor with a slide valve and slide stop mounted end to end in communication with the intermeshing rotors has means for changing the volume ratio during operation by stepwise movement of the slide stop and for changing the capacity during operation in infinitely variable fashion, both in response to system operating conditions. In the event of interference between the movements of the slide stop and slide valve, the components are designed so that the movements of the slide stop overpowers that of the slide valve.

  • Solid state compressor control system
    Patent number: 4227862
    Abstract: A solid state system for controlling a compressor or pump which is driven by a motor, the compressor being loaded or unloaded manually or automatically and proportionally to maintain a selected suction-pressure setpoint and to maintain the load on the drive motor within a motor-current setpoint limit, the system having start-up and shut-down sequences which have timed stages including a delay to permit the building up of oil pressure prior to loading of the compressor and including the automatic loading and unloading of the compressor incident to start-up and shut-down. The control includes monitoring of temperatures and pressures associated with the system and automatic shut-down in response to malfunctions internal to the system, and includes automatic shutdown in response to external malfunctions as selectable options, and further includes separate malfunction indicators with a circuit for providing their operability.

  • Heat transfer device and method
    Patent number: 5461878
    Abstract: A heat transfer device for cooling a fluid has powered means for moving the fluid to create a primary fluid flow, a heat exchanger, and direction controlling surfaces for directing the primary fluid flow toward and through a first portion of the heat exchanger, thereby cooling the fluid flow. The direction controlling surfaces then split the primary fluid flow into a first and second subsidiary fluid flow, and direct the second subsidiary fluid flow through a second portion of the heat exchanger, thereby cooling it to a second temperature which is lower than the first temperature.
