Title: Simultaneous production of aromatic hydrocarbons and isobutane
IPC: C10G69/10
Filed: 1972-08-10
Abstract: A naphtha boiling range charge stock is converted into aromatic hydrocarbons and isobutane via a combination process involving catalytic reforming, separation and hydrocracking.

Title: High energy arc ignitor for burner
IPC: F23C9/00
Filed: 1976-09-13
Abstract: A main burner oil gun in which hard to ignite liquid fuels can be burned, including an ignition means for the oil gun which will reliably light the oil gun time after time. The oil is sprayed from the oil gun tip in the shape of a hollow cone. Air is introduced surrounding the oil gun, and flows over a baffle plate located transversely of the oil gun, creating eddies of air, some of which break through the curtain of fuel issuing from the tip in a conical shape. This current of air that breaks through the fuel carries some fine droplets of fuel along with it, and forms a recirculation zone extending back to the oil gun tip. The ignition means is located within the hollow conical fuel flow, along the inner edge of the recirculation zone, so that the initial flame established is carried back to a point directly in front of the oil gun tip.

Title: Dynamic brake blending for an inverter propulsion system
IPC: H02P3/22
Filed: 1977-08-05
Abstract: The stator terminals of an adjustable speed a-c induction motor are connected to a source of d-c electric power by means of an inverter, and a system is provided for blending both dynamic and regenerative electrical braking of the motor whenever it decelerates. The brake blending system comprises a plurality of braking resistors respectively coupled by a corresponding switch in parallel with the power source. The switches are controlled by a control circuit which responds to motor terminal voltage, motor angular velocity and the difference between the commanded and actual motor torques to determine the additional current which the motor could regenerate without exceeding commanded parameters. When the additional current corresponds to that current which can be absorbed by adding an additional stage of braking resistance, the control circuit actuates a switch to add a stage of dynamic brake resistance. The control circuit also monitors the voltage of the source and removes braking resistance in steps to maintain source voltage within selected limits in order to maximize the current fed to the power source and thus maximize regenerated energy. In an alternate embodiment the control circuit determines the admittance of the source and utilizes the admittance to maintain source voltage substantially constant by removal of dynamic brake resistance in order to force more regenerative current to the source.

The other memory is a reference image memory (14) and is updated with the content or the real time memory (12). During the correlation the contents of the memories are displaced in relation to each other and an error signal, corresponding to the position of displacement for which maximum correlation is achieved, is made to control, through said control circuits, the alignment of the sensor. To make the tracking process insensitive to disturbancies and image elements which appear momentarily in the field of view for each scanning cycle only a part of the positions of the reference image memory (14) are updated by selection the addresses to said positions randomly or according to a predetermined rule of selection. By that the positions which are updated during one cycle in positions are distributed over the entire area of the memory.
