  • Patent number: 10315477
    Abstract: A vehicle suspension in which joint devices are interposed in coupling parts between a vehicle body and links serving as suspension components and coupling parts between the links and a wheel support component. Self-discharge type charge eliminators are provided on a surface of a specific component, which is at least one of the vehicle body, the links, the wheel support component, or the joint devices. The charge eliminator is configured to diselectrify the specific component by changing air around the charge eliminator to a negative air ion and attracting the air ion to positive electric charge of the specific component to neutralize the specific component, to thereby decrease a charge amount of the specific component and decrease charge amounts of rubber bushes and grease in the joint devices.

    Abstract: A fail-safe fluid transfer control apparatus has full redundancy in the response to various inputs such as overfill probe signals, ground detection signals, and the like. Independent microprocessor controllers independently evaluate the inputs and each output control signals to close a respective relay when the inputs indicate that fluid transfer may commence. The relays are arranged in series such that both must be closed for a fluid transfer to commence. The control signals from each controller include a static signal and an alternating signal, both of which must be properly output to close its respective relay. Each controller monitors the state of each relay, and discontinues its control signals if either relay appears to be malfunctioning. Each controller runs an different, independently written firmware program to process the detected inputs to prevent a common firmware error.

  • Patent number: 5570265
    Abstract: An elongate member is coupled by a socket at one end to the aircraft surface, whilst a tip forms its other end. The electrical resistivity of the elongate member, tip and coupling is equal to or greater than 10.sup.2 ohmmeter; and are preferably molded from a high temperature thermoplastics material having an electrical resistivity equal to or greater than 10.sup.16 ohmmeter. The plastics material is selected from the group comprising polyetherimide, polyethersulphone and polyetheretherketone. The material of the tip is provided with an embedded aligned array of carbon or silicone carbide fibers while the other parts of the discharger are loaded with carbon black or coated with the same thermoplastics material loaded with 4% by weight carbon black. The adhesive used to mount the socket has an electrical resistance between 5 to 10K ohms, while that of the socket is between 5 to 10M ohms, that of the elongate member between 20 to 100M ohms, and that of the tip is between 2 to 5 ohms.

  • Patent number: 5331502
    Abstract: A device for the protection of electronic equipment placed in public locations, such as electronic gasoline pumps and automatic teller machines, from damage by electrostatic charges on the bodies of individuals. The device is based on a movable, electrically conductive surface, which normally prevents access to the electronic equipment. As the user displaces the conductive surface in order to gain access to the equipment, charges will flow from the body of the user to the conductive surface and then to a grounded structure.

  • Patent number: 5179497
    Abstract: A ground-free device for removing static charges from semi-conductive or conductive bodies. The device includes a storage capacitor, a conductive contact connected to the storage capacitor, and an air capacitor connected to the storage capacitor, in which a voltage below the breakdown voltage of the air is imposed on the air capacitor, e.g., by an RC-controlled transistor oscillator circuit. The device provides high efficiency removal of static charge, e.g., from the metallic bodies of cars and aircraft.

  • Patent number: 4901195
    Abstract: The invention comprises a self-proving vehicle grounding system for placing the ground of a transportation vehicle at the same voltage as the ground of a loading rack and is intended for use in conjunction with an overfill protection system. The overfill protection system comprises a sensor unit on the vehicle and a base unit on the rack for disabling the loading equipment when the sensor detects overfill. The invention comprises three parts, a controller unit coupled to the filling station ground, a grounding bolt unit which is coupled to the transportation vehicle and a multi-conductor cable. The controller unit comprises a signal generator which produces a first electrical signal and a signal detector which, when it receives a specified second electrical signal at its input, enables the pumping equipment of the filling station.
