Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a new fertilizer compound of the ureaform type and to a method for the production thereof.  The new ureaform compound is characterized by the low average degree of polymerization between urea and formaldehyde.  The new compound has a nitrogen content of over 41% by weight and consists of cold water soluble nitrogen as the main fraction and cold water insolu-ble as the second fraction which is substantially free of hot water insoluble nitrogen.  The new ureaform compound is obtained by the condensation of urea and formaldehyde at a correct ratio between the reagents and termination of the reaction at a stage wherein excessive polymerization is prevented.  The reaction is carried out in a controlled system with a pH in the range of 3.5 to 4.2.  In particular useful are the systems H3PO4-KH2PO4 and H3PO4 -NH4H2PO4.  The new compound successfully conbines the advantage of both mineral water soluble nitrogen fertilizers and organic water insoluble slow-release nitrogen sources.

Abstract: ABSTRACT OF THE DISCLOSURE              A hermetically sealed motor protector or the like is disclosed in which a switch chamber is defined by a cylindrical, cup shaped element and a header welded to one end thereof.  A pair of insulated pins extend through the header substantially parallel to each other and on opposite sides of the center axis of the device.          A switch including a stationary contact mounted on one pin and a movable contact assembly supported by the other pin is arranged so that the line of action of the movable contact is along a diametrical plane inclined with respect to the pins.  Such structure facilitates the assembly of the device.  The structure is arranged so that the pin supporting the bimetal snap element limits movement of the free end thereof in a direction away from the fixed contact to reduce the tendency for calibration drift and fatigue cracking of the snap element.  In one embodiment, a shunt formed of flexible material is connected in parallel to the bimetal snap element to provide greater current carrying capacity.  In another embodiment, a resistance heater is connected in series with the bimetal snap element to increase current sensitivity.  The offset structure allows the use of a straight resistance heater, positioned closely adjacent to the center line of the snap element for good heat transfer.  The heater mounting is arranged to accommodate thermal expansion and contraction without altering the calibration of the device.

Abstract: Abstract of the Invention: A system for transmitting data from remote sensors to a digital processing system is disclosed herein.  The analog sensor output is converted to pulse width signals at the sensor location and converted from pulse width to digital data at the digital processor.  Delay circuits at each sensor location permits the use of a single interrogation signal to simultaneous interrogate each sensor.  The generation of the pulse width signal is delayed at each sensor location so that the pulse width signals from the sensors are serially received at the pulse width to digital converter.  Only a single data transmission line is required for transmitting the interrogation signal and the pulse width signals back an forth between the digital processor and the sensor locations.  In one embodiment, energy storage means are provided at each sensor location which provides sufficient electrical power for the operation of the sensor and the analog to pulse width converter.  This energy storage means is charged by the interrogation signal transmitted along the single data transmission line eliminating the need for providing individual power leads at each sensor location.

Abstract: ABSTRACT OF THE DISCLOSURE     Electric power control system useful for con-trolling the torque of a direct current electric motor which forms a portion of an electrical power circuit.  Power for the circuit is derived from a bank of batteries.  The control system comprises a current sensing device in the power circuit having an output that constitutes a correction voltage proportional to current flow.  A variable reference voltage control device varies the reference voltage.  There is a series pass transistor in the electrical power circuit.          A linear operational amplifier in the emitter circuit of the series pass transistor is coupled as a comparator to both the correction voltage and reference voltage.  The amplifier has an output voltage that varies in response to differences between the correction and reference voltages. The output of the amplifier is connected to the base of the transistor so that the output voltage controls the equivalent resistance of the transistor.  The circuit is arranged so that for any one reference voltage the current flow through the elec-trical power circuit is approximately constant.
