Abstract: Case 04-4245-U..S. APPLICATION OF GEORGE E. HERSHEY AN ADJUSTABLE OVERLOAD MECHANISM FOR A   DIFFERENTIAL PRESSURE TRANSMITTER              ABSTRACT An adjustable overload mechanism for a differential fluid pressure transmitter includes a first and a second overload control diaphragm and an adjustable spring pressure means for applying an adjustable preload pressure to the control diaphragms.  The spring pressure means for each diaphragm includes a spring such as a Belleville washer spring located between a diaphragm back-up plate in contact with a side of the control diaphragm and a wedge shaped support for the Belleville washer spring.  A wedge shaped drive means is arranged to be selectively movable with respect to the wedge shaped spring support while maintaining the sloping wedge surfaces in contact.  An adjustable drive screw is connected to the drive wedge to provide a means for changing the relative position of the support wedge and drive wedge.  The relative motion between the two wedge shaped elements displaces the support wedge transversely to the Belleville washer to change the height of the Belleville washer which affects the preload or spring pressure against the control diaphragm.  Each control diaphragm is used to control the valving of a fill fluid in contact with a respective barrier diaphragm subjected to an input fluid pressure. The fill fluid is pressurized by the movement of the barrier diaphragm and transmits the input pressure to a pressure sensor.  An excessive or overload input pressure overcomes the preload or spring pressure biasing the control diaphragm to divert the fill fluid displaced by the barrier diaphragm to protect the sensor from the overload pressure.

Abstract: APPARATUS FOR LOCKING THE IRIS APERTURE OF A CAMERA     ABSTRACT OF THE DISCLOSURE           Apparatus is provided for automatically controlling or locking the iris aperture of a camera.  The brightness level of a signal produced by the camera is detected and an automatic control circuit responds to this detected brightness level to energize an iris drive, thereby establishing the iris aperture. The actual size of that aperture is represented by an aperture signal.  This aperture signal is used by a control signal generator to generate a control signal corresponding thereto.  A selecting circuit is operable to select either an automatic control mode wherein the iris drive is energized by the detected brightness level of the signal produced by the camera, or an iris lock mode therein the iris drive is energized to maintain the iris aperture at a fixed size irrespective of changes in that brightness level.  An iris lock circuit responds to the selection of the iris lock mode for storing the control signal which is generated just prior to the selection of the iris lock mode, and compares the stored control signal to the aperture signal that is produced during the iris lock mode to energize the iris drive as a function of the difference therebetween.  In the iris lock mode the automatic control circuitry is disabled.          The iris aperture thus is fixed at a size determined by the stored control signal.

The energy management system includes a microcomputer for controlling the above-described cycling and ON-OFF functions. A hand-held programmer is provided to input machine ON-OFF times to the microcomputer, the ON times defining sales periods. The microcomputer has data stored therein related to cooling characteristics of different types of machines which may be selectively accessed by manually-actuated selector switches. This enables retrofitting of the energy management system into various types of vending machines.  The energy management system also provides increased cooling during high volume sales periods, morning warm-up prior to the beginning of a sales period, periodic continuous cool-downs to maintain acceptable product temperatures, and continuous cool-down following individual vends during a non-sales period.  Safety features are also provided in case of microcomputer malfunction or power failures to protect the vending machines.

Abstract: ASYNCHRONOUS DATA TRANSMISSION METHOD AND CIRCUITRY            Abstract A method and circuitry are disclosed for asynchronously transmitting binary data over a communication pair without the use of start or stop bits. During a non-data transmitting state a quiescent differential voltage, which is intermediate to the binary data differential voltage levels, is placed on the pair. The start of a data transmission is signaled by a transition of the differential voltage from the quiescent state voltage to the binary voltage of the first data bit of the data transmission.  Since all data transmissions are of known bit lengths, the end of a data transmission is determined by counting data bits. (Fig. 1)

Abstract: SERIAL KEYBOARD INTERFACE SYSTEM                         ABSTRACT     In data processing systems it has been proposed that a keyboard and a data processing unit be interconnected through a data line and a clock line so as to transmit keyboard outcodes bit-serially through the data line and to transmit a keyboard out clock signal through the clock line. This could result in false operation however due to noise being induced in the interconnecting cables from both the data and clock lines resulting in false operation and incorrect data being transmitted.  The present invention which provides a serial keyboard interface system overcomes the problem of erroneous transmission of keyboard data due to noise pulses induced in the interconnecting lines.  Data signals are generated at the data processing unit indicating whether the correct number of bits of a data frame are counted for the received signal.  If incorrect number is received then the status signal which is returned to the keyboard causes a retransmission of the signal.

Abstract: A monitoring and control system for a heating, ventilating and air conditioning (HVAC) unit which provides zone control in plural zones in which each zone includes a control thermostat that is interfaced with the monitoring system so that each zone thermostat controls the HVAC unit as well as a damper unit for that particular zone thereby enabling independent zonal control in a multiple zone system which uses a single zone HVAC unit. The monitor considers individual zone needs, damper positions, amount of demand in the zone, mode of the zone damper and other factors which affect the comfort of zone occupants and, in response to signals from the thermostats, decides how and when to control the HVAC unit so that, in effect, a single zone HVAC unit becomes a multiple zone system. The system is comprised of two or more computerized thermostats which control both the HVAC unit through the monitoring control and the air distribution system of each zone through the damper for each zone, creating a heating, cooling, variable air volume and variable temperature control system. The thermostats also operate under control of signals received from the monitor.
