  • Patent number: 5666021
    Abstract: A lamp holder includes a base and two electrical contacts for forming a connection with a bulb having an envelope around an electrical filament having two wires extending therefrom. Each wire forms a loop protruding from the envelope, the two loops being at opposed ends of the envelope. Each electrical contact of the lamp holder has a wire with a hook at its free end and formed to engage one of the two loops of the bulb, so that a shorter one of the wires engages the one of said two loops at the nearer end of the bulb and the other larger spring wire engages the other of said two loops at the far end of the bulb, in a manner that induces a spring tension in the wire. Thus, the bulb is held suspended between, and in electrical contact with, the two loops.

  • Patent number: 5660617
    Abstract: An apparatus and method for maintaining continuous flow in a closed loop test system, of a multiphase composition such as that utilized and obtained from oil and gas wells and the like. The method and system provide a test structure whereby a study of the changes in a multiphase composition (gas/liquid/solid) flow can be studied. Specifically, the method and apparatus provide for pressure boosting the gaseous components of the multiphase composition after separation from the liquid and solid components of the system. A hydrostatic head through which the liquid and solid components flow provides the necessary potential energy-kinetic energy exchange such that when the pressure boosted gas is recombined with the downcomer liquid/solid components, continuous flow of the multiphase composition is maintained. Pressure and temperature controls permit the accurate maintenance of pressure, temperature and flow conditions so as to imitate a real-world environment for multiphase composition flow.

  • Patent number: 5661406
    Abstract: Methods are provided for detecting and locating leaks in liners used as barriers in the construction of landfills, surface impoundments, water reservoirs, tanks, and the like. Electrodes are placed in the ground around the periphery of the facility, in the leak detection zone located between two liners if present, and/or within the containment facility. Electrical resistivity data is collected using these electrodes. This data is used to map the electrical resistivity distribution beneath the containment liner between two liners in a double-lined facility. In an alternative embodiment, an electrode placed within the lined facility is driven to an electrical potential with respect to another electrode placed at a distance from the lined facility (mise-a-la-masse). Voltage differences are then measured between various combinations of additional electrodes placed in the soil on the periphery of the facility, the leak detection zone, or within the facility.

  • Patent number: 5655346
    Abstract: A structural mounting system for mounting of structural components includes a base section and a co-operating section each of which in use is secured to a respective structural component and which are assembled together. The base section in cross section includes an undercut and the co-operating section in cross section includes a leg, having a toe projecting laterally to engage the undercut. When the sections are being coupled together the co-operating section is rotated about its longitudinal direction relative to its final position so that lateral movement of the toe to engage beneath the undercut requires the co-operating section to rotate about the longitudinal axis relative to the base section to adopt its final position. Spaced linear restraint points and a rotation restraint point together defining a triangle of points of contact to make the assembly of sections rigid.

  • Patent number: 5643142
    Abstract: An exercise treadmill having a direct drive AC induction motor controlled by an AC motor driver/controller. The driver/controller is itself controlled through programmable circuitry having a display and keyboard with user input options. The controller receives signals from a speed sensing device attached to the AC induction motor to maintain the rotational speed of the AC motor within preselected limits. The AC induction motor is attached to one or more flywheels and directly engages, through a drive roller, a walking belt. The matched combination of an AC motor driver/controller with appropriately sized flywheels allows utilization of a variable speed AC induction motor for the direct drive of the treadmill belt.

  • Patent number: 5642880
    Abstract: A simple training device to teach a baseball batter to utilize a proper batting position. The training device is a mat marked with a first indicia designating home plate and a plurality of second indicia showing sequential segments for the batter to place his feet. The mat further includes a pressure sensitive area for temporarily indicating the position of the batter subsequent to the swing of the bat. The mat may be used alone to achieve a proper batting stance and proper foot positioning in relation to home plate or with at least one measuring means for measuring a point located in the strike zone of the batter identifying the height of a level swing of the bat. This measured specific distance correlates to a proper distance from home plate the batter should position himself to hit the ball with the "power zone" of the bat with a full arm extension of the leading arm. The training device teaches the novice batter the most advantageous position to consistently hit the ball with the bat.

  • Patent number: 5642022
    Abstract: An aircraft window shade speed control system which allows the coordination of window shade movement speed throughout an aircraft using a single set-point device for each window shade. Each window shade is moved by an electric motor, and its travel is limited by upper and lower limit switches. Voltage is applied to each motor by a motor control module that is relatively insensitive to variations in aircraft electric buss voltage and motor current requirements. A remote operation switch allows the pilot of the aircraft to open or close all window shades in the aircraft simultaneously, and to be assured of their ultimate position by observing only the window nearest his own position.

  • Patent number: 5638575
    Abstract: A vacuum cleaner includes an electric motor which drives a suction fan to draw air and debris into the cleaner via an inlet. The air and debris pass along a passageway and creates a suction at a bleed way to draw air through the motor and out of a compartment. Air enters the compartment through vents (not shown) in a side of an outer housing. The arrangement enhances the cooling of the motor and uses air uncontaminated with debris.
