Abstract: 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.

Abstract: 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.

Abstract: The change in slope of a bore, conduit or pipeline is determined by supporting a pair of pivotally interconnected rigid components in the bore with the ends of the components and the pivotal interconnection therebetween located on the centerline of the bore. The change in slope between the components at the pivotal interconnection therebetween is detected, and this change in slope, because of the manner in which the rigid components are connected, is the same as the change in slope of the bore or pipeline in which the rigid components are placed and is in proportion to the strain in the surrounding pipeline. Apparatus is provided for determining the change of slope in a bore, in this manner, and is particularly adapted for use in pipelines being laid or retrieved.

Abstract: A timing system having a pair of conductors connected to an alternating voltage source through a switch. The system includes a first charging circuit across the pair of conductors consisting of a first condenser, a diode and an impedance whereby the condenser charges at a given rate. A second charging circuit across the pair of conductors, consisting of a rectifier, a trigger tube and a second condenser and current limiting resistance, acts as a timing circuit. The second condenser receives incremental charges and after a predetermined delay charges above a predetermined minimum value. A third charging circuit is connected across the trigger tube and second condenser and includes a resistance and a third condenser, with a second trigger tube and a resistance across the third condenser. When the second condenser reaches the above predetermined minimum value, the voltage on the third condenser fires the second trigger tube and generates a voltage pulse across its resistance which is supplied to the igniting electrode of a silicon control rectifier which conducts to discharge the first condenser through the operating coil of a relay. The discharge current from the first condenser rises above the pull-in value for the relay and remains above the hold-in value for the relay for a predetermined time after which it drops below such hold-in value. The relay is shown controlling the solenoid valve for a gas burner system. The gas burner system is provided with flame igniter and flame monitoring means. The flame monitoring means is provided with switches which cause the relay to remain closed in the presence of the flame, to remain in an open state upon failure of the flame to ignite and to recycle the system once upon a subsequent flame failure. The entire system can be recycled by opening the switch to the voltage source and then reclosing it.

Abstract: In a smooth top gas range including a shell construction defining an open top, a plate of heat resistant glass material closes the top of the shell to enclose a plurality of gas burner units therein. An air-impervious plate separates the shell into upper and lower air flow chambers and means is provided in the upper chamber to confine the products of combustion formed by each of the burners and isolate them from the upper chamber. The confining means serves to direct the products of combustion into the lower chamber of the shell construction which communicates with the atmosphere through an opening in the shell, so that the lower chamber defines a common exhaust for the products of combustion formed in each of the burner units. A blower is provided for drawing air into the upper chamber of the shell construction in order to cool the smooth top heat resistant plate during operation of the range and discharges this air into the lower chamber in order to dilute the products of combustion therein prior to their being discharged from the shell.

Abstract: A system for recording the amount of gas which is metered each day by reading-out the unit measurements of a meter which reads a continuing total. The continuing total of the meter is read monthly, and a printer record shows the amount which is consumed each day of the month. The read-out mechanism and an automatic printer are operated by gas flow once every 24 hours under the control of a battery-operated clock. Other selected print out cycles, such as hourly read out, can be selected by utilizing a battery-operated clock of the proper rotation cycle.
