Abstract: A disposable, centrifugal separator for separating contaminants from contaminated oil is disclosed. The centrifugal separator has a shroud which defines a first chamber and has a hollow rotor rotatably mounted in the first chamber and defining a second chamber. Oil under pressure is admitted to the second chamber through concentrically arranged tubes or spindles and past a low pressure shut-off valve. The oil flows into the first chamber through tangential reaction nozzles in the rotor to cause contaminants to migrate toward the sidewall of the second chamber under the influence of centrifugal force. The shroud and rotor are permanently closed so that the entire assembly may be discarded when a significant amount of contaminants has been deposited on the sidewall of the second chamber.
Abstract: A suspension ceiling system is disclosed which includes main tee members and cross tee members which can be assembled in a variety of relationships. The main tee members are provided with similar first end connections at each end and the cross tee members are provided with similar second end connectors at each end. The main tee and cross tee members can be end connected to produce main runs consisting of alternate main tee members and cross tee members. The cross tees can also be assembled through openings provided in the webs of both types of members to produce cross runs consisting solely of cross tee members. In the illustrated embodiment the second end connectors of the cross tees can be connected in three ways. They can be connected to first end connectors of the main tees, connected through a cross tee opening without a similar second end connector extending from the other side and can be connected to a second end connector extending in the opposite direction through the same cross tee opening.
Abstract: An improved knockout mechanism for forging machines or formers is disclosed in which the position of the knockout pin during the working operation of the machine is adjustably located by a tube nut threaded into the machine frame. In one embodiment, the tube nut is releasably locked in the adjusted position by a plate threaded onto the tube nut having a fulcrum on one side of the tube nut and a jackscrew on the other side at a location spaced from the tube nut greater than the spacing between the fulcrum and the tube nut so that a forced multiplication lever action is provided and secure locking is achieved without excessive jacking forces. In another embodiment, locking is provided by a lock nut threaded on the tube nut and connected to a fulcrum plate by a trunnion. A carriage is provided on the machine frame which supports means to operate the jacking screw and adjust the tube nut from locations accessible to the operator.
Abstract: A reinforced hose is disclosed having an overlapping spiral tube of reinforcing fabric embedded between inner and outer layers of extruded material in which the fabric is fully extended and tensioned during the manufacturing process and a good bond is obtained between the layers through the openings in the fabric. Also disclosed is a dual feed extrusion head for manufacturing such hose in which an outer nozzle assembly includes two annular plates bolted together and separable for easy cleaning. Such outer nozzle assembly is adjustably mounted on the forward end of the extruder head frame. A tubular inner nozzle assembly is provided with a nozzle at the exit end thereof located within the outer nozzle assembly and spaced therefrom. A fabric guide is positioned around the inner nozzle assembly and establishes the spiral configuration of the reinforcing fabric which in turn feeds in between the inner and outer nozzles. The inner nozzle is axially adjustable with respect to the outer nozzle.
Abstract: This disclosure relates to apparatus for drilling wells for oil, gas, water, etc., wherein the device for drilling is placed in a rigid cylindrical collar which is expanded and pressed in the walls of the well. The collar absorbs a reactive torque from drilling. In the upper part of the walls of the collar control devices are installed which send up the signals about outside collar pressure, temperature, etc., and thus indicate any complications in the process of drilling. The collar is coaxially joined at its upper end to a thin-walled, continuous tube which is formed from a coiled sheet by drawing the sheet through a rolling-up system of rollers. The tube is axially extended and retracted by a mechanism which has two or more systems of tube moving elements which are symmetrically disposed relatively to a longitudinal axis of the tube and engage the external surface of the pipe column with forces which are sufficient to create the necessary friction forces for moving the tube.
Abstract: A trailerable utility crane having a compound articulated mast to provide variable working configurations and foldable on itself to provide a relatively compact storage configuration as well as an extended length sufficient to load and unload a tow vehicle. Transport wheels for road travel are carried by the mast in a manner that allows the base of the crane to be lowered to the ground automatically with extension of the mast. The mast is supported for azimuthal movement on the base and outriggers for stabilizing the base are safety-interlocked with the azimuthal support.
Abstract: A water lubricated rubber bearing is disclosed in which a compliment of staves is positioned within a bearing housing having a cylindrical inner bearing housing surface. When unstressed, the stave can be moved within the housing for installation or removal. Locking of the staves in the assembly is provided by producing tight frictional contact between the inner bearing housing surface and the exterior surface of the staves. Such locking frictional contact is produced by axially compressing the staves to increase their thickness and to produce tight frictional contact between the outer surface of the stave with the bearing housing along the entire length of the staves. Additional locking is provided at the ends of the staves by pins mounted on the housing assembly, which project into bores within the ends of the staves. Such pins augment the frictional locking at the ends of the staves to resist peripherally directed movement of the stave ends.
Abstract: A series of labels remain supported on a liner after a matrix of waste label material has been stripped from the liner. The adhesion of the matrix to the liner is weakened prior to stripping of the matrix by mechanically disturbing without severing, as by embossing, areas of the construction where the matrix overlies the liner. Areas where the leading ends of labels overlie the liner may also be similarly disturbed to make eventual peeling of the liner from the labels easier. In another aspect, the construction may be precrushed with a blunt die prior to die-cutting of the labels to eliminate "halo" effect upon stripping of the matrix.
Abstract: A control mechanism for a sequential timer is disclosed. The mechanism includes an axially movable timer shaft which is associated with a timer shaft extension or control knob in such a way that initial movement of the control knob to select a particular position on the timing cycle will axially move the timer shaft to open a circuit in the timer. The open circuit prevents arcing of switch contacts and short pulsing of current through solenoids and motors.
Abstract: The synchronizing mechanism for the unfolding of articulated carrier elements which are outwardly extendable or inwardly retractable in a bellows-type arrangement on each side of a satellite body comprises a system of gear-train units placed alternately at one end of a driving carrier element. The mechanism is adapted to cooperate with at least one drive motor for folding-back or unfolding the carrier elements.
