摘要： The present invention discloses a method and apparatus for maintaining cold carbonated water in a beverage dispensing device so that unacceptably warm water is not dispensed therefrom. A modified beverage dispensing apparatus is shown including a carbonated water supply, a cold plate, carbonated water supply line extending through the cold plate, and in fluid communication with a carbonated water plenum immediately adjacent and in fluid communication with a plurality of beverage dispensing valves. An electronic control device connected to a temperature sensing thermostat located in the plenum and to a solenoid discharge valve of the plenum. The control device is also connected to a temperature sensing thermostat in the cold plate and to a pressure sensor located in the line between the source of compressed carbon dioxide and the carbonated water reservoir. In operation, the control device provides for sensing of the temperature in the plenum so that the solenoid valve can be operated to discharge carbonated water from the plenum if the temperature thereof rises above a predetermined value. So that the water therein can be replaced by water of a suitable lower temperature. The control device also senses cold plate temperature and CO2 pressure so that unacceptably high temperature or low pressure respectively thereof is indicated to the operator and so that the control device can interrupt beverage dispensing.

摘要： A film drive mechanism is disclosed for use with a radiographic apparatus which provides continuous radiographs or x-rays of a selected portion of a subject lying in a horizontal position by simultaneously rotating an x-ray source and an x-ray film holder including an x-ray film about the subject. An x-ray film cassette is mounted in the film holder and while the film holder rotates about the subject, the film cassette is moved past an x-ray slit. The film holder includes a novel drive mechanism for moving the cylindrical film cassette, in which an x-ray film is placed, at the proper rate of speed to provide the desired x-ray during rotation of the source and film holder. This is accomplished by utilizing a sloped cam having a configuration determined by the desired focal trough to vary the relative rotation of the shaft of a motor driving the film and the housing of the motor.

摘要： In one embodiment, a relative location detection apparatus including a detection unit having a support board having a plurality of spaced reed switches mounted along a lengthwise axis of the support board. Each of the reed switches has a longitudinal axis oriented substantially perpendicular to the lengthwise axis of the support board. A high intensity magnet is coupled to the support board for movement relative to the support board and in a direction substantially parallel to the support board's lengthwise axis. The magnet has north and south poles that are oppositely positioned to one another and directed toward one another across a width of the support board and into periodic alignment with the longitudinal axes of the reed switches. The magnet has a magnetic force sufficiently focused so that the magnet actuates the reed switches individually thereby indicating the magnet's location.

摘要： A solid state switching controller for use with various types of oil well bailer pumps. Individually programmable steps with lockouts provide multiple mutual exclusivity between various circuit operations. A trickle charge battery system powers the control circuits. A tank overflow float protects against oil spillage. An automatic production rate adjustment circuit is provided which increases cycle time in proportion to the rate of production. The circuit includes a low power voltage detector for disabling the control circuits until the line voltage is acceptable. A three-phase power and control system with an isolation transformer for the controls avoids unreliable ground connections. The timers include a dividing circuit with an RC circuit. All power actuated apparatus are actuated by triac switches which are controlled by an opto driver. The bailer brake is pulse actuated for allowing the bailer to sink into crude oil without excess cable looseness.

摘要： A dental mirror warmer to prevent fogging when the mirror is placed in a patient's mouth includes a housing with a cover having an opening. Below the opening is a heating well to receive the reflective end of the mirror. The well has a stainless steel wall connected to a transformer which supplies high current at low voltage to heat the wall. The supply to the transformer is controlled by a photoresponsive device responsive to insertion of the mirror and a timing circuit which permits current supply for a short heating interval. A temperature sensor shortens the interval when heating cycles are initiated frequently. The photoresponsive device is mounted in the housing in juxtaposition with a light transmissive opening in a wall of the heating well. The photoresponsive device includes a source of light arranged to direct light into the heating well through the opening and a photoresponsive element arranged to receive light reflected from the reflective surface of a mirror inserted into the heating well.

摘要： A double sided primed circuit board is shown wherein one side is etched for receiving a plurality of surface mounted components constituting a control circuit. In one embodiment the control circuit provides for regulating the operation of a plurality to the beverage dispensing valves. An op-amp monitors the conductor for sensing the operation of the beverage dispensing valves as a function of a voltage drop there across. The conductor operates as a resistor, and any heating thereof that occurs as a result of the operation of the beverage dispensing valves is dissipated over the entire surface area of the circuit board. The control circuit also operates a dump valve for periodically dumping beverage if any of the valves have not been operated for a set period of time. The control circuit deactivates the operation of the dump valve during any sensed operation of one of the beverage dispense valves.

摘要： The present invention is for an automatic gate opening device where commercial electricity is not economically available. A hydraulic cylinder operated by a bidirectional gear pump moves a cylinder rod which connects to an opening rod. The opening rod is pivotally connected to one end to the gate and on the other end to a stationary location. Due to pivotal connections and a pivotal linkage near the middle of the opening rod, the gate may be opened and closed by the hydraulic cylinder. The hydraulic cylinder is also pivotally mounted. Electronic controls may be operated by a number of different type sensors, including limit switches on the hydraulic cylinder, sensors for detecting the gate location, manual switches or other traditional vehicle approach sensors. Power is provided by a storage battery, which battery can be recharged during daylight hours at a solar panel or by a traditional battery charger.

摘要： An improved liquid level measuring apparatus having a plurality of spaced reed switches having a microprocessor attached to the liquid level measuring sensor apparatus. The switches are wired together in parallel and in sets and are addressed by a shift register for providing a parallel to serial shift of the switch status position to the microprocessor. This allows a reduction in the number of conductors existing the sensor and providing an output signal indicating the vertical position of a float relative to the switches. A microprocessor control notes any inoperative switches, disregards the reading of the inoperative switches in calculating liquid level, and provides stored information to the measurement process for compensating for defective switches.
