Abstract: Abstract An A.C. motor is connected into a transistor  bridge which includes a small current sensing resistor.  The bridge is operated to supply alternating half cycles of current to the motor and resistor.  The voltage drop across the resistor is compared in a comparator with a reference voltage which is equal to a fixed voltage minus a percentage of the bridge D.C. supply voltage. When the voltage drop across the resistor exceeds the reference voltage a gate means is closed to render the bridge transistors non-conductive.

Abstract: ABSTRACT OF THE DISCLOSURE       A polymer-microemulsion complex useful for the enhanced recovery of crude oil is disclosed.  The poly-mer is polyethylene oxide or polyvinyl pyrrolidone and interacts with the surfactant of the microemulsion to form a physical association.  The resulting complex is characterized by a complexation energy of at least 2 Kcal/mole.  The polymer microemulsion complexes are stable at high salinity, reduce adsorption and reten-tion by the formation, lower interfacial tension, achieve retentions as low as 0.1 mg surfactant/gm sand at high salinity and provide for early banking, as well as high recovery of oil.  Enhanced oil recovery fluids using the polymer microemulsion complexes exhibit similar properties.

Abstract: ABSTRACT OF THE DISCLOSURE:    To enable a consumer of electrical energy to effect control of total energy consumption by various individual appliances and loads, each individual load has a control unit, conveniently in a plug top, which responds to pulses broadcast on the power supply wiring in the form of short duration interruptions of the waveform.   At each appliance a microprocessor unit counts the number of successive pulses in a predetermined time interval and operates an electronic switch if the received count reaches a predetermined number, which may be different for different loads thereby enabling selective control of the loads.   Provision is made for automatic restoration of supply if the overall energy consumption falls.   Provision can also be made for automatic resumption of supply after a predetermined time interval.
