Abstract: ABSTRACT OF THE DISCLOSURE A ventilator implemented completely with fluidic devices provides independent control of inhalation time, exhalation time and breathing gas flow rate.  The basic fluidic system comprises a low frequency oscillator which in the form of a flip flop is controlled in its two stable states by means of independently controlled time delay relays.  The output of the flip flop is amplified by a digital amplifier and operates an on-off valve which is used to direct breathing gas from the source to the patient. Independent control of the flow rate of the breathing gas is by means of a needle valve.  With this basic fluidic system, there are seven other features of the apparatus.  One is a maximum pressure control which on inhalation is responsive to the patient's breathing air pressure.  The second feature is a sensitivity control, which during exhalation is responsive to the patient inspiratory effort.  The third feature is a positive end exhalation pressure control.  The fourth feature is an intermittent mandatory ventilation control which permits breathing rates as low as one breath per minute.  The fifth feature is a manual control which allows the termination of the exhalation phase and initiation of the inhalation phase manually.  The sixth feature is a sensor which is responsive to the breathing gas pressure at the patient.  If the apparatus becomes detached from the patient, pressure cycling is modified and an alarm system sensitive to this pressure is activated.  The seventh feature is a safety valve which allows the patient to breathe atmospheric air when the supply pressure of the source gas fails.

Abstract: ABSTRACT OF THE DISCLOSURE        A telemetry system for a dynamoelectric machine to detect temperature at a location on said rotor and to provide a signal externally giving an accurate indication of the temperature. A resistance temperature sensor (or resistance temperature detector) is connected to a constant current source and the voltage drop across it varies with changes in temperature.  This voltage change is amplified and a voltage-to-frequency converter then  provides a signal where frequency varies with the changes in temperature at the sensor.  This signal is applied to slip rings on the rotor and brushes mounted on the stator conduct the signal to a frequency-to-voltage converter.  A voltage-to-current converter then converts the signal to a current signal whose amplitude varies with changes in temperature at the sensor.  This current signal is used for alarms or displays or controls.  To provide power to the resistance temperature sensor and associated equipment i.e. the constant current source, the amplifier, and the voltage-to-frequency converter on the rotor, an external DC supply is connected to the brushes and this is available on the slip rings.  A filter and a DC to DC converter are connected to the slip rings and provide the necessary power to the sensor, amplifier and converter on the rotor. The rings and brushes provide a reliable direct connection between the equipment on the rotor and the external equipment, and the power for the rotor equipment and the temperature responsive signals are superimposed on the slip rings.

Abstract: DEPTH CONTROL AND PROTECTIVE APPARATUS        FOR TILLAGE ASSEMBLY            Abstract of the Disclosure A depth control and protective apparatus is disclosed as particularly useful in a tillage assembly for sod seeding pur-poses.  The apparatus includes a pair of skids mounted upon a pivoted arm, which arm has also mounted thereon a pair of cutter wheels for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel.  Each skid is mounted for essentially vertical movement with respect to the associated arm and cutter wheel mounted thereon to thereby determine and control the depth of furrow cut by the associated cutter wheel.          A substantially circular plate has an oval aperture in the cen-tral portion through which the axle and drive for the cutter wheel extends, and an inwardly directed cylindrical flange ex-tends to the periphery of the circular plate to protect the axle and to provide for movement of the skid relative to the cutter wheel and axle.  A seed boot is fastened to the skid rearwardly of the cutter wheel by an ear extending above ground level be-tween the cylindrical flange of the skid and the seed tube at a point spaced from the lower end thereof.  Thus, regardless of the selected depth of the furrow cut, the tube remains in the same position relative to the ground.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus is disclosed for use in a record/playback system for providing improved alignment between a transducer and a recording medium on which information on has been recorded.  The direction and magnitude of any misalign-ment between the transducer and the recording medium is rep-resented by an error signal.  When the error signal indicates substantial alignment between the transducer and the record-ing medium  a train of equally spaced pulses is generated. When the error signal indicates misalignment between the transducer and the recording medium, at least one pulse is either added or deleted from the train of pulses depending on the direction of misalignment indicated by the error signal.  The pulse train is then used to generate a drive signal for effecting relative motion between the transducer and the recording medium, the phase of the drive signal varying in response to the addition of deletion of pulses from the pulse train.  The drive signal has a constant phase when the pulses are equally spaced, and has its phase altered in one of two selected directions when pulses are either added or deleted from the pulse train.  By thus varying the phase of the drive signal, alignment between the transducer and the recording medium is improved.

Abstract: Abstract of the Disclosure A flow of hot combustion gas from an open gas tur-bine plant surrenders heat via an intermediate forced-flow circuit to a vapor circuit system in which a hydrocarbon working medium flows.  The forced-flow intermediate circuit uses a liquid heat vehicle such as a mixture of diphenyl and diphenyl oxide to transfer heat from the hot exhaust gas of the open gas turbine plant to the working medium of the vapor circuit system.  This heat vehicle is passed through a plurality of successively connected tubes in the exhaust gas duct so as to reduce the amount of leakage should a leak occur in the tubes and, thus, the chance of an explosion.          The waste heat transferred to the vapor circuit system can be used to drive a compressor of a refrigerating circuit, e.g. used to cool a flow of natural gas in a pipe-line located in an arctic region.
