Abstract: Case 2716 THERMOSTAT CONTROL SYSTEM FOR AN ELECTRIC KETTLE                 ABSTRACT OF THE DISCLOSURE         A control circuit for an electric kettle is provided which turns the kettle off after water in the kettle boils. The control circuit includes a main thermostat for controlling the operation of the heating element. The control circuit further includes an auxiliary thermostat and a bias heating element for heating the main thermostat, being electrically connected in such a manner that precludes current from flowing through the bias heating element until the boiling condition is approached. When the auxiliary thermostat senses a predetermined value of temperature from the kettle shell, it effectively energizes the bias heating element which drives the value of temperature sensed by the main thermostat rapidly upward to a higher, predetermined temperature value. When the main thermostat reaches the predetermined higher value it turns the kettle off. Prior control circuits for kettles have not employed an auxiliary thermostat in this manner.

Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is a method of treating an agricultural pro-duct, including the steps of placing the product within a storage container; providing a forced air supply to the container; introducing a gaseous chemical into the container, the particular chemical being selected for minimal sorption of the chemical by the product; and circulating the air and chemical mixture within the container through the product at a low rate of flow, utilizing the forced air supply, for a time sufficient to evenly distribute the chemical through-out the product volume.  The rate at which the air is cir-culated is less than approximately .006 cfm/bu and is pref-erably maintained approximately between .0015 cfm/bu and .0008 cfm/bu.  Hydrogen phosphide (phosphine) gas generated from aluminum phosphide is preferred as the chemical when the process is used for fumigation, but other gaseous fumi-gants exhibiting a low rate of sorption by agricultural products may also be used.

Abstract: Abstract An integratable circuit is utilized for generating a temperature varying control voltage to be applied to a varactor diode to temperature compensate a crystal oscil-lator.  The temperature compensating circuit has a middle range circuit for creating a substantially linear current versus temperature variation in a middle temperature range, a cold-temperature range circuit operative below a predeter-mined temperature for creating a non-linear current versus temperature variation,a hot-temperature range circuit operative above a predetermined temperature for creating a non-linear current versus temperature variation and circui-try for summing said currents and generating a voltage proportional to the current sum.  The control circuit, which requires a regulated supply voltage, uses a diode string and differential amplifiers to generate the desired current versus temperature variation.

Abstract: ABSTRACT OF THE DISCLOSURE     A temperature-responsive valve for control-ling the flow of fluid comprises a housing having a chamber therein, an inlet port communicating with said outlet port communicating with said chamber and a temperature deflectable partition.  When the temperature of the fluid transmitted to said parti-tion reaches a first predetermined value, the de-flectable partition snaps to restrict with its surface the flow of fluid into said outlet port and remains in that position until the temperature of said fluid transmitted to said partition reaches a second predetermined value.  The deflectable parti-tion then snaps to permit the full flow of fluid into said outlet port.  The temperature-responsive valve is especially useful in showers for protec-ting users from discomfort or scalding in the event the temperature of the shower water rises above the desired value.

Abstract: SUBSTRATE BIAS GENERATOR              ABSTRACT OF THE DISCLOSURE           A substrate bias generator for an integrated circuit, metal-oxide-semiconductor (MOS) random access memory (RAM) is described.  The on-chip generator includes two input terminals for receiving first and second trains of periodic pulses.  The periodic pulses have the same frequency and are phase synchronized.  However, the first train of pulses has a greater duty cycle than the second train of pulses.  Amplitude transistions associated with the first and second trains of pulses are capacitively coupled to first and second nodes, respectively.  A pair of transistors are coupled to the nodes, one transistor for clamping the first node to ground when the second node receives a positive-going voltage transition, and another transistor for selectively coupling amplitude transitions from the first node to the second node.  In operation, both nodes are driven more negative with each successive incoming pulse until they reach about -5 volts for the case in which the amplitude of the incoming pulses is 5 volts.  A third transistor closes a current path between the first node and the chip's substrate when the substrate voltage is at least one threshold voltage more positive than the first node voltage.  As a result, the substrate voltage is driven to a negative level which is about one threshold voltage more positive than the furthest negative voltage level on the first node.
