    Abstract: 523,723. Pistons. LOCKWOOD & CARLISLE, Ltd., and CARLISLE, J. H. Jan. 13, 1939, No. 1152. [Class 122 (i)] A piston 1 is provided with a number of expansible pressure sealing rings 4 located in a single slot 6, and with a junk ring 7, the rings 4 being urged towards one end of the slot by resilient means located at the opposite end of the slot, the tension of the resilient means being adjustable. As shown, the resilient means consists of springs 2 accommodated in a divided ring 3. The tension of the springs 2 is adjusted by the use of packing washers 9. The sealing rings 4 may be separated by uncut rings 5.

    Abstract: A connector (10) includes a housing (12) having a bore (22) therein. A center conductor element (30) is positioned in the bore and includes a center conductor pin (60). The center conductor pin (60) is spring-biased to move longitudinally for being compressed. A ground sleeve element (32) is coaxially arranged around the center conductor element and is also spring-biased to move longitudinally in the housing bore for being compressed. A portion of the center conductor element (30) and ground sleeve element (32) are coupled together for moving together in the housing bore (22) when compressed. The compressed elements maintain their same coaxial position in the housing bore (22) with respect to each other when the connector (10) is compressed.

    Abstract: An electrical connector including a shell sized to receive and retain an electrically insulating housing insert, where the housing insert includes a cavity for receiving and retaining a wire-terminating electrical contact therein. The shell and housing insert each include a plurality of mating key features designed to provide a plurality of indexing positions for the housing insert, each index position defining an angular orientation of the housing insert relative to the shell to control a direction of the wiring exiting the electrical connector.

    Abstract: A multi-component fluid delivery system includes a heater system. The heater system includes an improved fluid preheating system based on a high conductivity fluid heat exchange manifold that is coupled to external heater elements (e.g., powered via electricity). These techniques can provide more surface area for heating fluid and is external to the fluid passages, making service or replacement much easier. These techniques can utilize etched foil or wire wound heater elements that operate at a lower internal temperature than cartridge heaters, and thus can be inherently more reliable.

    Abstract: Embodiments of the present disclosure are directed to a coating apparatus including a spray applicator configured to discharge a coating material toward a surface of a workpiece, wherein the spray applicator includes an air shaping orifice, and wherein the spray applicator is configured to generate an electric field between the spray applicator and the workpiece and a positioning system configured to adjust a position of the spray applicator relative to the surface of the workpiece. The coating apparatus further includes a control system configured to regulate operation of the spray applicator and/or the positioning system to: maintain the spray applicator within a coating distance between 20 millimeters and 100 mm from the surface of the workpiece during spray operations of the spray applicator, maintain a flow rate of shaping air through the air shaping orifice between 150 normal liters per minute (Nl/min) and 300 Nl/min during spray operations of the spray applicator, and maintain an electrical potential of the electric field between 30 kilovolts (kV) and 40 kV during spray operations of the spray applicator.
