A level control apparatus is disclosed for controlling a liquid level between a maximum and a minimum. An elastic circuit generates a reference pulse which receives the pulse and triggers the generation of first and second reference pulses. The first reference pulse has a width which corresponds to the function of the maximum level of liquid and the second reference pulse has a width which corresponds to the function of the minimum of liquid. A capacitance probe supplies an output to a level sensing means which generates an output control pulse which varies in time with respect to the liquid level. A response circuit receives the first and second reference pulses and the control pulse and generates a first response when the reference pulse and the control pulse occur at a time which indicates that the fluid is at the maximum level and a second response signals when the second response indicates that the fluid has dropped to a minimum level with a time provided between the minimum and maximum where no response is developed.

Apparatus for controlling temperature in accordance with a source temperature that includes a clock pulse generating circuit that triggers each of first and second mono-stable multivibrators which provide opposite phase pulse outputs having durations controlled by the R-C time of thermistor sensing components. A retriggerable monostable multivibrator is then controlled in response to pulse duration difference to provide toggle energization of heating and cooling sources.

An improved electrical energy storage battery is provided having a case, at least two porous electrolyte containers positioned within the case, a solid hydrogel positioned within the case and between the electrolyte containers, the hydrogel containing an effective amount of an electron transferring agent to render said hydrogel conductive, at least one anode positioned within at least one of the electrolyte containers, at least one cathode positioned within at least one other of the electrolyte containers, a second solid hydrogel positioned within the container for the cathode, said gel being saturated with a compound selected from the group consisting of zinc chloride, zinc oxide, cadmium chloride, and cadmium oxide to render same conductive, and a third solid hydrogel positioned within the container for the anode, said gel being saturated with a compound selected from the group consisting of chromium chloride, chromium oxide, and alkali metal-containing chromate salts to render same conductive. The electron transferring agent employed in the solid hydrogel is selected from alkali metal salts, alkali metal hydroxides, alkaline earth metal salts, and alkaline earth metal hydroxides.

The integrity of mine roofs and rock bolts is tested by determining the natural frequencies of the roof and bolt. The roof is struck at a plurality of locations and the resulting vibrations sensed with accelerometers. The output of each accelerometer is separated into a plurality of signals of different frequencies by a comb filter having selected band passes. The amplitude of the outputs of each of the band passes of the filter are used to determine the condition of the roof and bolt adjacent each accelerometer. The high amplitude signal resulting from the initial impact of the striking implement is electrically gated from the accelerometer output.

An electronic guidance system for a push drill that is remotely guided by the operator. The system functions to maintain continual indication as to the attitude of the drilling apparatus, i. e. , pitch, roll and distance to rock formations overlying or underlying the drilled stratum, with such indication being made available to the remote operator so that he can control the progression of the drilling apparatus. The drilling apparatus utilizes an instrument package adjacent the drilling mechanism which samples pitch and roll data through accelerometer output, and which monitors the distance of the drill head from adjacent rock formations by means of gamma ray count.

A fluid level indicator circuit is used in cooperation with a probe attached to a long wire where the probe has first and second electrodes for contacting the surface of the fluid and leads communicating to the indicator circuit. The water level indicator has a low current high gain transistor and a power source which has sufficient potential to not only properly reverse bias the transistor when the probes are out of contact with the fluid but also properly forward bias when the probes are in contact with conductive fluid. A meter and current adjusting device are provided in series with a collector and emitter to provide an indicator when the probes are in or out of the water. The circuit also has a light to give a visual indication.

A portable apparatus for determining the moisture content in welding electrode coatings is described. The apparatus is suitable for field use, and comprises a source of low voltage direct current, a means for transforming low voltage direct current to high voltage direct current, an electrical circuit including a current indicating means and contacts attachable to a welding electrode whereby the welding electrode coating is included in the electrical circuit. A method of operating the apparatus to determine the amount of moisture in a welding electrode coating is also described.
