Abstract: An improved apparatus is disclosed for filling containers with a liquid. The apparatus is very efficient and the containers may be filled in a small fraction of the time formerly required. The flow of liquid into the containers may be controlled with great precision and without spilling or wasting the liquid. The filling spout has the added advantage of being dripless. The apparatus is especially useful in filling a large number of small open top containers such as communion cups with a liquid such as grape juice.

Abstract: An automatic shut-off nozzle has a first diaphragm responsive to the liquid in the tank being filled reaching a predetermined level to automatically stop flow through the nozzle. Flow also is automatically stopped when a second diaphragm responds to inactivation of a pump supplying the liquid to the nozzle. When a venturi poppet valve is located downstream from a main poppet valve in the nozzle, the venturi poppet valve has a bleed passage extending therethrough to enable the pressure upstream thereof and acting on the second diaphragm to be reduced to zero the pump is inactivated.

Abstract: A nozzle for filling containers with liquid, with automatic closing of the nozzle, when they are full, by means of a flow valve which is controllable by a delivery lever via a detachable connection. The connection is acted upon by a switching device which, according to the pressure in a pressure channel terminating at the outlet orifice of the nozzle, causes the valve to close.

Abstract: Flexible hose for liquefied gases, comprising a tubular body of biaxially oriented polypropylene film (2) arranged between an inner helically wound wire (3) and an outer helically wound wire (4), said wires being wound at the same pitch but having the windings displaced by half a pitch width from each other.

Abstract: An automatic valve bag placer is disclosed which is constructed to sequentially remove valve bags from a bag magazine, manipulate the end flap of the bag for opening, open the valve and place the same on a fill spigot. An improved bag magazine and feeding assembly in which a plurality of trays are mounted on the elevator and feed stacks of limited number of bags onto a pick-off support structure ensures that bags are picked off one by one. The bag is oriented by a horizontal and then a vertical conveyor to a near vertical orientation, which orientation is retained thereafter until the bag is placed on the fill spigot. A pair of carriages and associated clamping means first pass the bag through a deflector assembly to orient the valve for opening, and then, after opening, the second carriage carries the bag to and inserts the same over the fill spigot.

Abstract: The invention relates to an internal obturator for a pipe for use in separating two spaces inside a pipe. The obturator comprises a rigid hollow body comprising two end plates connected by a cylinder having a lesser diameter than the end plates between which an annular inflatable bladder of a jack is provided extending around the cylinder. The jack is inflated to apply a cylindrical wall against the inner surface of the wall of the pipe. The wall which is independent of the bladder of the jack may be connected by its ends to the end plates or may simply be inserted therebetween.

Abstract: A stopper for an inspection hole to give an X-ray inspection probe access to the inside of a pipe or other apparatus wherein the stopper comprises a cylindrical outer component (6) having an open end and an inside screw thread (10), said outer component being welded to the wall (1) of said pipe or other apparatus and leaving an outside end protruding therefrom, and a cylindrical inner component (11) having a blind hole and an outside screw thread, said inner component being screwed into the inside screw thread of the outer component and having an outside end which is welded (12) around its periphery to the projecting outside end of the outer component, said blind hole being equipped with means (13) which allow the inner component to be unscrewed from the outer component after the weld (12) joining the outside ends of said components has been broken.

Abstract: A weight-coated pipe has an innermost anti-corrosion layer, a helically-wound covering of a cementitious sheeting having a reinforcement of organic fibrillated film network arranged as a plurality of superposed layers. This covering is applied in a post-cracked condition so that constituent parts of the next layer of concrete penetrate the micro-cracks and form a good bond. An outer layer of helically-wound sheeting similar to the first-mentioned covering serves to protect the weight-coating of concrete from impact damage.

Abstract: A system for filling containers with liquid and the like which reflects ultrasonic pulses from the surface of the liquid as it rises in the container being filled. Range gates at predetermined fill levels control throttling down and/or shut off of the filling liquid.

Abstract: A quick connect/disconnect coupling assembly (10) defining a fluid flow path is disclosed. The coupling assembly (10) includes a female coupling member (12) adapted for connection to a conduit (14) and a male coupling member (18) adapted for connection to a conduit or container (20). The female coupling member (12) includes a poppet valve assembly (90) which functions as an automatic shut-off when the female coupling member (12) is not interconnected to the male coupling member (18), the male coupling member (18) being adapted for removeable partial insertion into the female coupling member (12). The valve assembly (90) of the female coupling member (12) further includes a needle-like structure (92) for puncturing a penetrable membrane (28) at the front end of the male coupling member (18) upon insertion of the male coupling member (18) into the female coupling member (12) thereby enabling the flow of fluid therethrough.

Abstract: A plug assembly which is resistant to loosening in response to thermal expansion and contraction is provided. The plug assembly comprises a deformable sleeve which is closed at one end and open at its opposite end to provide a chamber which receives a wedge slidable with respect to an expandable ring mounted in the chamber adjacent its open end. When pulled axially, the wedge expands the ring which, in turn, expands the sleeve radially outward into engagement with the inner wall of the item to be plugged. A retainer surrounds the out-pulled wedge and cooperates with a nut and threads on the wedge to tension the same and thereby apply continuous outward pressure to the sleeve. Preferably, the outer periphery of the sleeve is provided with a series of alternating edges and grooves which cut through any scale which may be present on the inner surface of the plugged item.

Abstract: A rotary transfer subsystem is described for transferring production fluids, electrical power, hydraulic power, and control signals across a rotating interface between an offshore process vessel and a flowline bundle of service hoses and high-pressure hoses which are connected to a deepwater production riser system. Tensioning devices are also described for maintaining a selected tension on terminal hoses between the interface and the vessel while the vessel weathervanes during maintenance of position in a watch circle above the riser system. The subsystem and the tensioning devices are mounted on the vessel which is equipped with a powered turret within a circular moonpool and is capable of performing most subsea service functions on the riser system without major equipment support.
