Abstract: A BRIGHTNESS CONTROL CIRCUIT FOR    A VACUUM FLUORESCENT DISPLAY              ABSTRACT OF THE DISCLOSURE       A circuit for controlling the brightness of a vacuum fluorescent display having filament terminals and connected to anode or segment biasing means includes a transformer having a filament winding connected to the filament terminals.  The transformer is driven by a 60-cycle power source.  An electronic switch, including a transistor, is connected between a center tap of the filament and the anode biasing means (at a common ground) and circuit means open and close the switch at a 60-cycle rate.  The ratio of time during which the switch is closed to the time during which the switch is open is variable to control the brightness of the display.

Abstract: ABSTRACT OF THE DISCLOSURE           A plastic container is made by separately molding of thermoplastic resin material at least two divided portions of the container, each molded portion being provided with a dividing end face and a cutout extending along the dividing end face.  The molded portions are then held in a position of desired assembled relationship to provide a key-shaped jointing groove including the cutouts extending between the opposed dividing end faces and having an opening extending around the whole periphery of the container.  The key-shaped jointing groove is filled by injecting through the opening a thermo-plastic resin material which is heated to such a temperature that the thermoplastic resin material is in plastic form and heats, melts and fuses the thermoplastic resin material of the divided portions at the surfaces of the jointing groove which are contacted by the molten thermoplastic resin material.  The thermoplastic resin material in the groove and fused thereby is cooled to effect hardening and to unite the molded portions into one body.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a nozzle bushing for a sprue gated injection molding system.  The elongated nozzle bushing has a hollow stainless steel inner core portion through which extends the runner passage from the molding machine to the cavity gate and around which is located a helical electric heating element.  A highly conductive copper portion is cast over the heating element and the inner core portion, and covered by a stainless steel outer sleeve.  A steel spiral blade member is fixed in the runner passage to impart a curving or swirling motion to the melt as it flows from the gate into the cavity.          This provides the advantage of improving product strength by reducing unidirectional molecular orientation of the melt, as well as reducing stringing of the melt when the mold opens to eject the product.

Abstract: Case 640 COMBINATION VACUUM RELIEF VALVE AND PRESSURE, RELIF VALVE          WHICH ARE PROTECTED FROM THE ATMOSPHERE            Abstract of the Disclosure A vacuum relief valve assembly includes a vacuum valve member located below a top cover plate and is thus protected from the atmosphere.  First passageways defined in part by a bottom cover plate provide communication between the out-side atmosphere and the lower surface of the valve.  Second passageways provide communication between the upper surface of the valve and the inside of the container.  When the pressure in the container is below atmospheric, atmospheric pressure acting on the bottom of the valve lifts the valve and air flows through the first and second passageways until atmospheric pressure is reached in the tank.  A pressure relief valve is mounted for pivotal movement re-lative to an opening providing communication between the pressure in the tank and the first passageways to vent pressure in the tank.  The pressure relief valve is protected from the atmosphere by the top cover plate, and in one embodiment, by the vacuum relief valve.

Abstract: ABSTRACT           In a principal aspect, the present invention is an improved system for servicing an electronic engine tester. The system includes a display actuator, coupled to the processor.          In response thereto, the processor provides a display signal which results in the simultaneous listing, on a single page, of the engine parameters, monitored and analyzed by the tester, the respective processed output signals therefor, and the respective analog input signals therefor.  Based upon this display, the operator or serviceman can simultaneously evaluate the raw data signals received by the processor and the corrected and scaled output data signals for each engine parameter, irrespective of test page order.  This permits an immediate determination of potential hardware and software problems.  In another aspect, the improved service system includes a calibration actuator, coupled to the processor.  Responsive to the calibration actuator, the processor provides a calibration signal which results in the display of the calibration constants for each engine parameter monitored and analyzed by the tester. The display includes an identification of the calibration constant and the magnitude thereof.  Based upon the magnitude of the calibration constant or constants, the operator can determine whether a potential hardware problem exists.

Abstract: ABSTRACT OF THE DISCLOSURE           A remote-control assembly is provided herein for controlling a crane or the like having a movable boon or the like, in which the crane in-cludes an electrical control circuit for controlling the movable boon or the like, the assembly thus serving to insulate the operator of the remote-con-trol assembly from electric shock.  The remote-control assembly includes a remote-control box having a plurality of fluid valves, a converter box in-cluding a plurality of fluid valves and means for operating the fluid valves and a converter to box including a plurality of pressure switches.  The pressure switches each include a movable member having at least one electri-cal ocontact mounted thereon, each of the pressure switches being formed by a separate housing for enclosing the movable member and the electrical con-tact.  A plurality of fluid lines connecting the fluid valves to operate the movable members in each of the pressure switches; and a plurality of electrical lines connecting the electrical contacts of the pressure switches to the electrical control circuit on the crane for operating the movable boom or the like.  Advantageously, an arrangement is thus provided which substantially eliminates the possibility of the operator of the remote-control box receiving an electrical shock when the boom strikes a high-voltage line.  As will be understood, if a boom strikes a high-voltage line, the electricity will discharge through the chassis of the crane and the electrical control circuits and the electric lines between the plug and the converter box.  However, the electricity will not discharge through the pressure switches, or the plastic tubing, or the remote-control box connected to the plastic tubing.  In this manner, the operator of the remote control box is insulated from such an electric shock.

Abstract: ABSTRACT      This invention relates to a liquid fuel combustion device which gasifies and burns liquid fuel, and particularly to a liquid fuel combustion device which gasifies liquid fuel by the heat of bomcustion produced by the device itself and continues combustion.  In this type of liquid fuel combustion device, there is a phenomenon in which the rate of combustion decreases with decreasing oxygen concentration.  Utilizing this phenomenon, the invention detects the difference between the combustion exhaust gas temperature and the room temperature exceeding a given value or falling below another given value so as to detect the oxygen-deficient state, thereby stopping the combustion or giving warning.
