  • Patent number: 5418444
    Abstract: An automatic ignition controlled battery charge and discharge system for vehicles such as RV's boats and the like, that have an engine with a charging system connected to a main battery, an ignition switch controlling the engine, and a plurality of auxiliary batteries. When the engine ignition is turned on, the main battery connected to a generator or alternator of the engine is placed in parallel with a plurality of auxiliary batteries for charging, and when the engine ignition is turned off, the main battery is isolated from the plurality of auxiliary batteries, to allow the auxiliary batteries to discharge without affecting the voltage potential of the main battery.

  • Patent number: 5357078
    Abstract: A power supply for a consumable electrode arc welding system includes a power transformer adapted to be coupled to an AC source and having a rectified secondary coupled through a series inductor to the electrode. The rectified current is chopped by a MOSFET switch array controlled by a relatively high frequency pulse width modulator having a selectively variable pulse width to supply a pulsed unidirectional current flow to the welding gun. A bridge rectifier is connected across an auxiliary winding of the transformer to provide a supply voltage to the modulator.

  • Patent number: 4881873
    Abstract: A bilge pump switch sensing the presence of bilge water by measuring the density of water by using an ultrasonic field penetrating the water, the field extending through the housing of the switch. Thus the internal elements of the switch are isolated from any contact with the water. The ultrasonic field detecting the presence of water activates sensing means in said switch housing to activate the pump, delay means being provided against false pump starts due to wave action as caused by a rocking boat.

  • Patent number: 4396881
    Abstract: This invention relates to an electric battery charger for a storage battery such as an automotive battery in which the improvement consists of the visual display of such indicia that it informs the operator of the condition of charging present between the battery charger and the battery to be charged as to whether the battery is being properly charged, whether it can be charged and that it is fully charged.
