Abstract: An improved method for removing proppant from fluid used in an oil and gas well for reuse in future operations. The proppant is separated from the well fluid and transported to a materials collection tank. A crane then transports the materials collection tank onto a processing boat. On the processing boat, the proppant is vacuumed from the materials collection tank to a hopper. The proppant is then discharged from the hopper into a holding tank for treatment and reuse. In a first alternative embodiment, two hoppers are positioned above each other so that the proppant can be added to the upper hopper and then fed by gravity to the lower hopper. A valving arrangement maintains vacuum within the interior of at least one hopper at all times to provide a continuous vacuum operation. A conduit discharges from the lower hopper into the holding tank.

Abstract: An independent back memory module is disclosed that is permanently installed at a security gate installation. The memory module has a nonvolatile memory and it is positioned within the system so that it automatically has a communication link with any gate controller installed. The memory module records a history of the operation of the system. The memory module retains operational information regarding the system and information identifying the gate controller, gate controller board and the setup of the particular installation. The memory module also retains information regarding changes made in the setup of the system. Whenever a new gate controller board is installed information in the memory module is transmitted to the new controller board.

Abstract: A system is disclosed for providing a backup power supply for a security gate system. In a preferred embodiment it includes a primary power supply, an AC motor and an auxiliary DC motor that share the same accessory devices including controller, movement mechanism, sensors, communication unit, etc. The auxiliary DC motor has its own independent DC power supply. If the primary power supply fails the auxiliary power supply takes over and moves the barrier between the open and closed positions as needed without interruption of service.

Abstract: An adjustable loading apparatus for supporting a long span beam in a flexure test by a load application device is disclosed. The apparatus includes an upper support structure including an elongated support beam, at least one support bracket adjustably mountable along a longitudinal span thereof, and a saddle member selectively pivotally mounted in the at least one upper support bracket for engaging with a specimen under test. The upper support structure is positioned normal to the load application device and a lower support structure is positioned parallel and co-planar to the upper support structure. The lower support structure includes an elongated support beam, at least one spacing member adjustably mounted along a longitudinal span thereof, a lower support bracket adjustably mounted along a longitudinal span of the spacing member, and a saddle member selectively pivotally mounted in the lower support bracket for engaging with a specimen under test.

Abstract: A Joint-cover rubber strip for preparing and painting two adjacent surfaces separated by a hollow joint, comprises a single-piece body 2 having a horizontal rectangular face 4 at one end which is parallel to another wider face 18. One of the faces 4 is defined by two inclined rectangular surfaces 3 and 5 and the other face 18 is provided with two inclined sides 16 and 17. The whole strip comprises a single-piece elastomer body disposed in the center of two projecting parts 8 and 9.

Abstract: A system and method is disclosed to the elimination of cross talk between inductive loop detector units in a security system. The system includes appropriate devices for assigning different operational frequencies of each loop detector circuit to avoid cross talk. In a further aspect it provides a system and method for determining actual operational frequencies of various loop detector circuits in a security system and for changing the resonant frequencies to eliminate cross talk.

Abstract: A modular terminal block with one or more built in surge protectors is disclosed. The terminal block contains all of the surge protection devices for a security or other type of system. The connectors of the terminal block also have indicia on the connector pairs of the terminal block that match the connectors of the terminal block with the connectors of the system to which the surge protector is to be connected. The identifying indicia on the connectors pairs provides for the easy identification of the proper interconnections between the terminal block and the system it is designed to protect.

Abstract: A method and apparatus for moving a gate a distance in a predetermined period of time. In one embodiment the current load for an electric motor to move a gate is first measured to determine whether the gate's motion is being hindered or helped. A microprocessor then controls voltage supplied to the motor to enhance or retard the evolved power of the motor according to the load and the predetermined time.

Abstract: A fuseless power supply regulator circuit is provided for a gate security system. The circuit has sub-circuitry and components to monitor current levels of current from an unregulated power supply and to stop the follow of current into the circuit when the unregulated supply is providing an excessive amount of current and/or the gate security system is drawing an excessive amount of current as a result of a short or otherwise. The sub-circuitry continues to monitor current levels of current coming from the unregulated power supply and when the current levels drop to acceptable levels reopens the main circuit and allows current to flow into the power supply regulation circuit and on into the power supply circuit.

Abstract: An apparatus for activating and reprogramming various features of a security system that relies on a read/write chip that inserts into a socket connected to the control unit of the security system. Depending on the activation codes written onto the chip, when the chip is inserted into its socket, it activates or deactivates various features and parameters of the system. The speed the gate opens and closes at, how long it remains open etc. can be varied. Additionally, the chip can be used to activate advanced features of the system built into the system when originally installed. Thus, if a customer desires to upgrade to advanced features of the system this avoids having to install additional features since they having already been built into the system and are activated by insertion of a chip with the appropriate code.
