  • Most significant digit location
    Patent number: 4758974
    Abstract: After performing a floating point addition, it is desired to normalize the sum; that is, shift the most significant digit of the mantissa into the left-most digit location, and adjust the exponent accordingly. Prior art techniques required performing the addition before calculating the number of shifts required. The present technique determines an approximate shift from the addends during addition, resulting in a significant time saving.

  • Full output voltage driver circuit using bootstrap capacitor and controlled delay circuitry
    Patent number: 4546276
    Abstract: An MOS driver circuit which provides full VDD and VSS output logic levels uses a bootstrap capacitor and a delay circuit whose delay is controlled by potential of the terminal which is bootstrapped. Adverse effects of processing variations are limited because the delay time of the delay circuit is determined by the components which selectively control the potential of the bootstrapped terminal.

  • Chemical injection control system for fire fighting
    Patent number: 4324294
    Abstract: A system for injecting chemicals into a fire fighting system of the type using a plurality of water hoses and having a source of water and a source of chemicals. A servo motor system is connected to automatically meter a certain ratio of chemicals into the water supply. The servo motor system is responsive to the total flow to control the chemical pump to pump a certain ratio of chemicals into the water supply even if the total flow varies. Various modifications are disclosed.

  • Safety bar for fire trucks
    Patent number: 4273360
    Abstract: Safety bar for a fire truck of the type having an open space behind the cab for carrying firemen. A bar is mounted to protect men from falling out from the space. The bar extends across the space and has movement up and in with respect to the truck. Stops restrain the bar from movement down or out with respect to the truck.

  • Automatic scan flow meter means
    Patent number: 4262287
    Abstract: Automatic scan flow meter means for systems of the type supplying a plurality of lines. A plurality of flow meters are each connected to a line and to a control panel. Display means are mounted on the control panel. Scanning circuit means are connected to scan the flow meters and sequentially display the flows from the flow meters.

  • Flow measuring means
    Patent number: 4224826
    Abstract: Flow measuring means in a pipe having turbulent flow. A chamber is inserted in the pipe. The chamber having a diameter substantially larger than the diameter of the pipe. A flow meter is mounted in the pipe downstream from the chamber. The chamber substantially reduces turbulence in the pipe and provides a reliable flow measurement.
