摘要： A compact absorption refrigeration unit has a central mounting core containing a generator about which substantially all of the components of the refrigeration system are mounted in a predetermined configuration. The generator has heat transfer fins secured to its surface which have a predetermined configuration that allows the fins and generator to absorb heat at the optimum rate at which heat can be transferred thereto without damage to the fins. The unit also includes an evaporator having a centrally positioned reservoir and a helical passageway providing a flow path for a heat exchange medium and containing a fluted helical heat exchanger tube which provides a countercurrent refrigerant, thereby to chill said heat exchange medium. In one embodiment of the invention the unit is provided with a compact boiler for use in heating the heat exchange medium, thereby permitting the unit to be selectively operated for both heating and cooling.

摘要： A starting impulse generated when the crank shaft of an engine passes a specific point and starts a counter that counts impulses for one revolution. During the same revolution, another signal corresponding to a specific engine event starts another counter that continues until the end of the same revolution. A computing circuit uses data from the counters to determine engine speed and the angle at which the engine event occurs and presents this information as a numerical readout. A mark signal may be generated as a cursor for cathode ray tube display of ignition or other engine waveforms. The cursor can be moved to any point along the waveform by a manual control, and the angle at whatever point is selected will be presented in the numerical readout.

摘要： A welding head clamping and oscillating assembly is disclosed for use in a welding machine having means for supporting and moving the assembly along a joint to be welded. The assembly includes a support platform connected to the assembly supporting means of the welding machine and a support plate slidably mounted on the support platform for reciprocal movement in a direction transverse to the joint to be welded. A welding head clamp is pivotally mounted on the support plate for arcuate oscillating movement in a direction substantially parallel to the direction of the slidable mounting of the support plate and a reversible stepping motor is operatively connected to the clamp for oscillating the clamp about its pivot axis. An electrical control circuit is also provided for the stepping motor and includes logic circuitry for producing a pulse signal at a predetermined frequency and a binary counting circuit for counting a predetermined number of pulses from the signal and producing an output signal when the predetermined number of pulses is counted. The circuit includes means responsive to the output signal and operatively connected to the motor to drive the motor alternately in first and second directions in response to successive output signals from the binary counter thereby to oscillate the welding head clamp assembly about its pivot axis.

摘要： A tilting brazier including a flat cooking pan having upper and lower surfaces, has a plurality of heat pipes mechanically and thermally bonded to the lower surface of the pan in heat transfer relation therewith. The heat pipes have evaporator and condenser portions with substantially the entire condenser portion of each of the pipes being located beneath the pan while the evaporator portions thereof extend beyond the periphery of the pan. A gas fired burner positioned adjacent the evaporator portions of the heat pipes supply heat thereto so that heat supplied to the evaporator portions thereof is uniformly transmitted to the pan through the condenser portions of the heat pipes.

摘要： A fluid heater, particularly adapted for use with a swimming pool, has a powered gas burner therein for supplying high intensity heat to pool water flowing in a tubular heat exchanger adjacent the burner plate. The heat exchanger is arranged in a heater housing to define therewith a flow path adjacent the tubes for the products of combustion from the burner whereby heat by convection is supplied to the tubes from the exhaust gases. The input end of the heat exchanger includes a valve member adapted to maintain a predetermined rate of flow of water through the tubes and to bypass excess water back to the pool.

摘要： A deep fat frying unit having a glass cooking vessel adapted to hold a supply of cooking oil. The unit is heated by an annular infrared radiant gas burner assembly which heats the oil primarily by infrared radiation passing from the burner assembly directly through the vessel wall. The burner assembly is above the bottom of the vessel so that there is a cool zone at the bottom of the vessel which eliminates burning food sediment deposited therein. The radiant heat is absorbed by the oil in an annular zone adjacent the vessel wall and this produces oil circulation by convection upwardly along the wall and downwardly at the center of the vessel, but without overheating the oil.

摘要： Variable orifice meter assembly for determining the total volume of gas flowing through the assembly by measuring only a portion thereof, comprising a positive displacement meter associated with a first stage input regulator and a second stage output regulator. The regulators are directly connected for gas flow therebetween and are also connected to the meter for gas flow from the input regulator through the meter to the output regulator. The output regulator is provided with a valve assembly comprising a secondary valve connected to a main valve, the main valve controlling the direct flow of gas from the input regulator to the output regulator and the secondary valve controlling the flow of gas through the meter. Both valves are mechanically activated for simultaneous unitary operation. The meter is activated by the portion of the total gas flowing therethrough but is calibrated so as to record the total flow of gas through the assembly.

摘要： An electrical system for igniting gas burners to provide safety features as well as an efficient and dependable means for igniting the gas flame. Gas is ignited by a glow coil and a sensor- or probe-type resistance unit imposes a control function to turn off the gas supply if the burner is not ignited within a predetermined time period. The sensor also closes the gas valve whenever the sensor is no longer heated.
