The second end cap has a central opening, and an annular sealing device bounding the opening which receives and seals to the standpipe and includes through-passages fluidly interconnecting the fluid channel in the core with flow opening(s) along the standpipe or in the lower end of the housing to a drain port.

Abstract: A cutting installation for a fabric web comprising an unwinding unit, a downstream dancer unit serving as a buffer, and a downstream cutting frame with a cutting unit disposed thereon. At least two gripper beams extending parallel to the cutting unit and guided along a lateral rail arrangement are displaceable across the longitudinal extension of the cutting frame, and each gripper beam on one side is carried by a first support tower which is displaceable along the rails, and on its opposite end is provided with a telescopically extendable extension piece. The extension piece can be docked with a second support tower arranged on the opposite side and traveling along. The support towers are adapted for adjusting the height of the respectively carried gripper beam, such that each gripper beam, as it moves along the cutting frame, can travel over the other gripper beam.

Abstract: A deflector at the downstream end of a fuel tube deflects incoming fuel into an annular fuel channel in a fuel swirler of an injector. The deflector prevents direct impact of the cooler fuel on the exposed walls of the swirler body. The deflector can be formed by a tab or other integral portion of the heatshield, or as a separate piece fixed to the heatshield or swirler body. The deflector minimizes disruption of flow through any flow slots that are covered by the deflector, and may have i) a relatively small circumferential extent, such that the deflector covers only a few flow slots, ii) flow openings or slots that allow a portion of the fuel to flow inwardly of the deflector into the otherwise covered flow slot(s), or iii) a space or gap between the side(s) of the deflector and the inner walls of the annular channel.

Abstract: A hydraulic drive system includes a pair of hydraulic drive motors connected in series. Each motor includes a hydraulic circuit with a spring-biased directional control valve and a pair of check valves. The circuits are located in the end cover for each motor, and are in fluid communication with the respective motor and with each other. The circuits are responsive to the pressure differential across the motors, due to the load and direction of the vehicle, and direct flow to one wheel or the other. Flow is directed to the inside motor when accelerating and/or climbing, while the outside motor is allowed to turn freely to compensate for the different turning radius. This reverses when the vehicle is going downhill and/or decelerating, when the motors are braking. If the drive wheel loses traction, the flow and pressure shifts to the other wheel (or to both wheels), until traction is regained.

Abstract: In a vehicle, having a fixed supporting structure and a load movable relative thereto, a jam tolerant actuating system, a method for controlling this system including: Locating a physical coupling/decoupling mechanism between the load and an actuator assembly as close a practicable to the load; constructing the coupling/uncoupling mechanism to be reversible, and hence testable; and controlling the connection/disconnection via decision making electronics which will detect any system failure by monitoring, at a minimum: actuator main motor load and speed, and actuator output load. Also set forth are specific embodiments of pivotable rotary geared actuators as well as linear ball screw type actuators embodying the coupling/uncoupling mechanisms of this invention.

Abstract: A bracket for a refrigeration valve includes an elongated flat plate bent in half with the two halves of the plate lying in parallel, adjacent relation. The inner bracket half includes an opening closely receiving the inlet fitting of the valve, and a predetermined internal geometry closely receiving the external profile of a fixed nut on the fitting. The outer bracket half also includes an opening configured to closely receive the fitting, and a dimension such that it butts up against an outer side surface of the nut. The outer bracket half is mechanically fixed to the fitting, such as by riveting, brazing or other means. Fasteners are received through corresponding apertures in the bracket halves to attach the bracket to a support surface. The cooperating geometries of the inner bracket half and the nut prevent the bracket from rotating with respect to the fitting during assembly.

Abstract: A filter assembly includes housing enclosing a replaceable filter element. A support core is provided in the housing, and includes an extension and locking assembly. The element includes a ring of filtration media with a pair of end caps. The first end cap includes a central opening to receive the support core.

The extension and locking assembly includes a bypass member and a locking member, which are in locking engagement when an element is absent in the housing. The second end cap includes internal protrusions which engage the locking member when the filter element is installed to disengage the bypass member from the support core, and allow the element to be inserted and the cover to be installed.

Abstract: An atomizing injector includes a metering set having a swirl chamber, a spray orifice and one or more feed slots etched in a thin plate. The swirl chamber is etched in a first side of the plate and the spray orifice is etched through a second side to the center of the swirl chamber.

The cylindrical air swirler passage is located in co-axial relation to the spray orifice of the plate of the fuel metering set such that fuel directed through the spray orifice passes through the air swirler passage and swirling air is imparted to the fuel such that the fuel has a swirling component of motion. At least one air feed slot is provided in fluid communication with the air swirler passage and extends in non-radial relation thereto.
