A battery monitors by which an individual cell in a wet cell battery may be monitored for variations in the level of electrolyte contained in the cell. More specifically, the invention relates to a universal electrolyte level indicator which may be attached to, and made part of, battery powered mobile equipment of all types for the purposes of providing a warning indication to the operator of the equipment that water needs to be added to the batteries contained therein.

Method of providing a indication signal to indicate a level of

A battery cap sensor probe including a generally hollow body having an interior chamber through which a conductive probe passes. The probe has a first end adapted for emersion into the electrolyte of a battery cell and a second end adapted for electrical connection to an electrical circuit. The second end is preferably a terminal portion crimped to the remaining portion of the conductive probe.

A dust detector ring assembly for detecting extremely small quantities of particulate contamination in air being taken into the carburetor of an engine is disclosed. The assembly includes a series of infrared light emitting diodes alternately interposed with a like series of infrared light detecting diodes and arranged in a circle around an interior surface portion of a frame defining a passageway of circular cross-section therethrough. A light beam generated by each of the emitters is directed against a different one of the detectors so that the light beams intersect one another at a common point in the passageway. The sensitivity of the assembly is thus greatest at the common point of intersection of the light beams and decreases proportionally moving away from the intersection point toward the defining surface of the passageway. A flexible circuit board is formed in a circle and is connected to the emitters and detectors. A flat circuit board is connected to the circular circuit board. The emitters and detectors are inserted into shafts radially projecting through an annular retaining ring. A ring-shaped infrared light glass filter is attached to an interior surface of the retaining ring and defines the passageway. An electronic circuit for sensing and counting interruptions of the light beams and for activating an alarm when potentially engine-damaging amounts of particulate matter flow into an engine carburetor air intake system is also disclosed.

A ballast and control circuit for use with fluorescent lights. The circuit aids energy efficiency by removing heater current flow once the lamp has ignited. The circuit also uses time delayed inductive storage to allow delivery to the lamps of increased operating current without a concurrent increase in power utilization.

The inverting and non-inverting input terminals of a voltage comparator are connected across the cables of a battery charging system through R-C circuits having substantially different time constants. When the cables are disconnected from a battery being charged, the rapid increase in output voltage of the charging system momentarily reverses the relative values of voltage at the comparator inputs and produces a control signal which automatically deenergizes the battery charging system.

This disclosure relates to a dust control apparatus including mobile drilling rig having a peripheral skirt which collects dust during a drilling operation and delivers the same to a dust collector having a chamber housing and a plurality of filters, each filter being cleaned by a high pressure air line through an appropriate solenoid valve and a sequencing control circuit for operating the solenoid valves to sequentially deliver high pressure air into the filters so that the dust collected thereon can be blown therefrom dropping into the chamber and outwardly therefrom through a discharge opening.

An electrostatic discharge protection device adapted to be clipped onto the insertion type edge connectors of a circuit card assembly. The device includes a shunt circuit for electrically short circuiting the edge connectors of the card to provide a path of low resistance between them.

Electrostatic discharge protection device

This disclosure relates to a temperature controlled animal house, particularly a dog house, which includes first and second chambers, the first of which houses an animal and the second of which includes means for generating heat which is blown into the first chamber, the heat generating means including a socket to receive a conventional light bulb with the heat therefrom being blown by a fan into the first chamber. A thermostat in the first chamber regulates the temperature thereof and a second thermostat in the second chamber prevents overheating in the second chamber.
