Abstract: A gasoline dispenser control and data system comprising a central office and a plurality of local stations, each station having dispenser control functions, data storage functions and communication functions. The station has a dispenser control mode and data entry mode. In the dispenser control mode a dispenser may be set to dispense gasoline, such dispensing of gasoline resulting in the production of pulses which are accumulated in a counter. The dispenser may then be reset for the next sale. Upon reset the counter is returned to zero, and the previous sale is stored in a temporary memory for recall and display, also being stored in two separate permanent memories, one of which is accessible to the station operator and the other of which is not accessible to the station operator. In the data entry mode the station operator can enter data into some but not all permanent memories. The station data system may be telephoned by the central office and each memory interrogated. The central office may also enter new data in the station data system. There is a provision for interrupting transmission for a limited time for operation of dispensers on a limited basis. There is also a provision for automatically entering data such as the amount of gasoline in storage tanks in the station memory, for ''''in use'''' and ''''ready'''' signals for each dispenser, and for an emergency off function.

Abstract: A variable D. C. power supply and a variable A. C. power supply are coupled onto the upper end of a single conductor cable at the earth''s surface and from the lower end of said cable to a well logging instrument. The A. C. voltage is used to provide filament power for the ion source accelerator tube. The D. C. voltage is used to provide power to fixed D. C. loads maintained constant by regulators once a threshold is reached. The D. C. voltage is raised above the threshold to control the pulsed acceleration voltage and hence neutron output by first feeding into a unijunction relaxation oscillator in combination with an SCR output which output is transformer coupled into a voltage multiplier circuit. An antilatch feature is provided for the SCR by transformer coupling the pulses on the SCR anode back to the base of a transistor in series with the cathode of the SCR. Two outputs of the voltage multiplier circuit are connected to the cathode and anode, respectively, of an ion source accelerator tube, the cathode being connected through a resistor to retard the ripple pulsing of the cathode to allow ionization of the accelerator tube.

C.电压用于为离子源加速管提供灯丝功率。 一旦达到阈值，则使用D.C电压为固定的D.C负载提供电力。由负载维持恒定。 D.C.电压升高到高于阈值以控制脉冲加速电压，从而通过首先馈送到单结张弛振荡器与SCR输出结合，输出变换器耦合到电压倍增器电路中来控制中子输出。 通过变压器将SCR阳极上的脉冲耦合到与SCR的阴极串联的晶体管的基极，为SCR提供了一个防污特征。 电压倍增器电路的两个输出分别连接到离子源加速管的阴极和阳极，阴极通过电阻器连接以延迟阴极的脉动脉冲，以允许加速管的电离。

Abstract: The improved turbo-machinery seal described herein includes an annular seal body encircling the turbo-machinery rotor shaft and disposed within the housing. The seal body includes a first end arranged to frictionally and sealingly engage a radially disposed face in the housing while the seal is exposed to a pressure fluid that biases the seal body toward the radial face. In one aspect, the seal body is provided with a recess in a portion of the bore adjacent the rotor shaft that is exposed to the pressure fluid providing a biasing force on the seal body in a radial direction. In another aspect, the seal body may be provided with a seal on the outer periphery thereof that engages the housing. The area thus isolated by the seal is vented to a low pressure so that the seal body is biased radially. The purpose of the radial bias on the seal body is to provide the seal with a predetermined direction of force so that predictable results can be obtained with respect to the shaft supporting characteristics of the improved seal.

Abstract: A tube expander operable with random length tubing having variable length projection beyond the face of header sheet into which the tube is to be expanded. Rollers in an expander cage are supported on a rotatable mandrel for insertion inward of the tube end. An open ended non-rotatable, tubular thrust collar is adapted to envelop the tube end and is secured about the cage at a predetermined location generally rearward of the rollers. Within the collar and biased toward the open end thereof is a slideable stop sleeve sized to abut the projecting end of the tube. On being advanced over the tube projection toward the header sheet for preliminary positioning, the collar engages the sheet face to register location of the rollers within the tube in alignment with the header sheet. Concomitantly with positioning of the collar, the abutting tube end acts to prevent sleeve movement as to effect relative displacement between sleeve and collar which can then be secured for operation of the expander.

Abstract: A fast neutron source is periodically switched between a pulsed mode and a continuous mode. A first gamma ray detection interval follows the pulsed mode to provide an indication of the capture gamma rays. A second detection interval occurs during the continuous mode to provide an indication of the capture gamma rays plus the gamma rays resulting from the inelastic scattering of fast neutrons. The first indication is subtracted from the second, resulting in an indication solely of the gamma rays from inelastic scattering. The pulses occurring in such intervals are further subjected to energy discrimination which provides information relating to carbon and oxygen content, such information being used with a ratio circuit to provide a carbon/oxygen ratio. In another embodiment, a pair of neutron sources, one pulsed, one continuous, provide analogous results. In still another embodiment, the borehole is first logged with a pulsed source and then later with a continuous source. In yet another embodiment, a shielding, rotating disk having alternate short and long windows is used between an alpha particle source and a neutron emitter to simulate the pulsed and continuous modes. An electrical signal functionally related to the lithology of the formations, for example, the silicon/calcium ratio of the formations, is used in conjunction with an electrical signal indicative of the carbon/oxygen ratio to generate an electrical signal indicative of the hydrocarbon saturation of the formations.

Abstract: A valve body is fabricated by injecting rubber through a channel extending along the central longitudinal axis of a cylindrical body having a conical-shaped end portion and out through a pair of transverse channels to form a flexible resilient sealing surface having a flexible lip, the resilient sealing surface being formed at a slightly greater angle than the adjacent metal frusto-conical sealing surface on the body. The central and transverse channels used for injecting the rubber serve as a mechanical lock between the resilient sealing surface and the metal body of the valve. In addition, the resilient sealing surface is chemically bonded to the metal body of the valve. A plastic valve guide having a continuous ring on one end and a centrally oriented guide portion having three arcuate surfaces equally spaced around the circumference of the valve body are arranged such that the valve body can move longitudinally within the valve guide.
