Granted: 1981-07-14
Abstract: PEAK DETECTING CIRCUITRY AND DUAL THRESHOLD CIRCUITRY THEREFOR Abstract of the Disclosure This peak detecing circuitry avoids false peak indication while using component circuits of smaller dynamic range and lower voltage energizing power supplies than is possible with contemporary circuitry. The electric wave having peaks for which the times of occurrence are desired, is applied between an erecting (non-inverting) input terminal of a differential amplifying circuit and a point of fixed reference potential.  A capacitor is connected between the inverting input terminal of the differential amplifier circuit and the reference point.  The differential output of the amplifier circuit is applied through individual amplifier circuits to the capacitor for charging and discharging it in accordance with the instantaneous polarity of the electric wave.  A unilateral impedor is interposed in the charging circuit in the form of a diode or a transistor for preventing discharge upon reversal of the electric wave slope.  Latching and like circuitry is coupled to the detecting circuitry for indicating the detection.  An electric connection, preferably including a diode element and/or a resistance element, is arranged between the indicating circuit and the amplifying circuit for dynamically altering the threshold from a high value as the peak of the wave containing noise is approached to a relatively low value as the peak of the wave containing timing information is approached.

Abstract: KEY TELEPHONE SYSTEM                        Abstract of the Disclosure To convert a multiple line, multiple telephone set installation into a key telephone system, a control unit is provided at each telephone set.  The control unit includes a regulated power supply, a control circuit, pushbutton line select and hold switches, and indicator lights packaged in a compact assembly which can be readily attached to the base of a standard telephone set or mounted separately.  Electrically controlled switching devices within each control circuit respond to the pushbutton line select switches to couple the telephone set to a selected one of the lines and automatically disconnect the set from the line when the call has been completed.  An incoming ringing  signal on any one of the telephone lines is detected by the control circuit and the ringing signal is automatically applied to the bell of the telephone set.  A line on which a call is in progress may be placed in a hold condition by operating the hold select button which thereafter enables the telephone set to be coupled to another line, if desired, for receiving or placing another call.  A conference call can be established by simulataneously operating the two or more line select switches which in turn cause the selected lines to be jointly connected to the telephone set.  The indicator lights on each control unit respond to standard central office supervisory signals which appear on the telephone lines and which represent on-hook (idle), ringing and off-hook (busy) line conditions, and also respond to a special hold indicating signal which is applied to the line by the control unit during the hold condition.  The control units of the various telephone sets operate solely in conjunction with the standard telephone lines that extend from the central office and no additional interphone wiring is required and no central control unit is needed.

Abstract: Abstract A method of heating a glass sheet which is moved on a conveyor which contacts one face of the sheet.          In order to reduce the contact between the contacted surface of each glass sheet and to keep the leading edge of each sheet clear of the conveyor, anticlastic bending of the sheet is caused, and the stable anticlastic shape of the sheet is determined such that the sheet is arched away from the conveyor transversely of the sheet with respect to the conveying direction and with the sheet having a reverse curvature along its longitudinal extent so that the leading and trailing edges of the sheet are bent away from the conveyor.  Anticlastic bending of the sheet is caused by producing a temperature differen-tial between the central  area and at least a part of the periphery of the sheet, for example, by heating said part of the periphery.

Abstract: ABSTRACT OF THE DISCLOSURE           A cooking appliance, such as a deep fat fryer, includes programmable control system which monitors the operation of the cooking appliance and enables appropriate actions at proper times.  The system includes a microcomputer which processes data and implements various timing and control functions.  A microcomputer multiplex input circuit includes control switches to select operational states of the appliance, has a diode matrix for implementation of certain input data, interconnects the microcomputer with other circuits to implement multiplexing of the circuits for additional input data, and includes a monitor circuit to turn off the appliance if multiplexing stops.  A temperature control circuit generates a signal responsive to the cooking fluid temperature and compares it with various reference signals representative of specified fluid temperatures, as called for by the computer.  The comparison results are multiplexed to the microcomputer. A cooking control circuit includes an oscillator with an integrating capacitor.  The cooking control circuit generates a voltage proportional the cooking fluid temperature, modifies it according to the desired doneness of the food being cooked and converts it to a current which charges the capacitor.  The oscillator provides a series of pulses which vary in frequency as the temperature of the fluid varies. These pulses are multiplexed to the microcomputer.  Output circuits connect the microcomputer to various contactors controlling operation of the appliance and to indicators, such as lights and a buzzer, which indicate the state of operations.  The control system provides a low heat energy melt state and a cooking state with energy input suitable for cooking food.  It signals when a load of food is done.     Abstract of the Disclosure continued.... Additionally it enables signals when unwanted temperature conditions exist and turns off the heat when comparison results indicate the fluid temperature has gone outside set limits.

Abstract: Title of the Invention FORCE LIMITER                    Abstract of the Disclosure A bidirectional force limiter for limiting the magnitude of a force applied along a line of action to a predetermined magnitude includes a slide assembly sup-ported for reciprocating movement along its longitudinal axis by the spaced guide plates of a support structure. A yieldable force-bias means, such as a helical spring in compression, is constrained between the guide plates, and means are provided for transmitting the applied force from the slide assembly to the biasing means to cause the slide assembly to displace and the biasing means to yield in response to the applied force.          The force limiter is suitable for use, in a preferred mode, with cargo-container spreaders which are adapted to attach to and detach from cargo containers. The spreader carries a plurality of locks which are adapted to register with and engage complementary lock receiving structures on each container.  A hydraulic actuator is linked to the locks to selectively actuate them between a locked position and an unlocked position to, respectively, attach the spreader to the container and detach the spreader from the container.  The force limiter is connected between the hydraulic actuator and the spreader frame to limit the applied locking and unlocking forces to a predetermined, safe magnitude.  The force limiter prevents excessively high hydraulic fluid pressure from damaging a jammed lock or over-riding safety devices designed to prevent unlocking when the spreader and attached cargo container are in a suspended position.
