    Abstract: A high-pressure, plunger-type liquid pump (10) including a liquidmanifold (16) that includes a plunger chamber in the form of an axial cylindrical bore portion (24) for slidably receiving a pressurizing plunger (20), and that also includes a valve chamber (42) coaxial with the plunger chamber (24) and in communication therewith for removably receiving a cartridge-type flow control valve (72, 161). The liquid manifold (16) includes a closure plug (36) to close the valve chamber (42). The cartridge-type valve (72, 161) is slidably received in the valve chamber (42) for enabling removal of the cartridge-type valve (72, 161) from the liquid manifold (16) without the need for separating the liquid manifold (16) from the pump drive housing (12). The cartridge-type valve (72, 161) is of a structure that includes in-line, axially spaced suction (100, 176) and discharge (136, 162) valves that are each spring biased into closed positions. High-pressure liquid is confined within a valve housing body (72, 160) that contains the suction and discharge valves, to minimize damage to the liquid manifold (16) as a result of pressure fluctuations and high-pressure flows. The cartridge-type valve (72, 161) is removable from the manifold (16) without the necessity of removing or even separating the manifold (16) from the pump drive housing (12).

    Abstract: A method of providing a metal preform having a semi-sold metal structure includes the step of determining a temperature profile for the metal to be converted to establish a temperature range indicative of a partially solid and partially liquid state of the metal. With this temperature profile, a metal preform is heated at a controlled rate from a temperature below the temperature range to a temperature within the range defined by the temperature profile to achieve a select percent by volume of liquid in the metal. This controlled heating to a desired temperature, which may be at a uniform rate, followed by holding at the desired temperature, thermally converts a dendritic structure of the material into a globular structure. The thermally converted metal preform is then recovered for subsequent use such as shaping into a desired article.

    Abstract: A method of forming a tube joint which can be used in a desalination plant includes providing a fluted tube (1), applying a sealant (51) to the tube end (19) and inserting the tube end (19) into a tube sheet or plate (3) to form a joint therebetween. After insertion, the inner surface of the fluted tube (1) is worked to deform external ridges of the fluted tube (1) and uniformly distribute the sealant (51) throughout the joint area. The fluted tube (1) is deformed using a roll expanding method. The fluted design of the tube (1) retains sealant (51) in the joint area during tube (1) insertion and expansion and takes advantage of the heat transfer characteristic of the flutes (9) to provide an improved joint construction especially adapted for heat exchange use.

    Abstract: A start-up method and apparatus for continuous casting of molten metal into a cast strip product includes initially casting a start-up alloy having sufficient strength, flexibility and casting surface release properties to achieve steady state casting conditions. A target alloy follows the start-up alloy being cast to produce a cast strip product of the target alloy composition. A start-up alloying vessel is disposed between the source of the target alloy and the casting apparatus to facilitate introduction of a start-up alloy into the casting process or formulation of a particular start-up alloy for initiation of the continuous casting operation.

    Abstract: A method of producing an aluminum-based alloy product having improved exfoliation resistance and fracture toughness which comprises providing an aluminum-based alloy composition consisting essentially of about 5.5-10.0 % by weight of zinc, about 1.75-2.6 % by weight of magnesium, about 1.8-2.75 % by weight of copper with the balance aluminum and other elements. The aluminum-based alloy is worked, heat treated, quenched and aged to produce a product having improved corrosion resistance and mechanical properties. The amounts of zinc, magnesium and copper are stoichiometrically balanced such that after precipitation is essentially complete as a result of the aging process, no excess elements are present. The method of producing the aluminum-based alloy product utilizes either a one- or two-step aging process in conjunction with the stoichiometrically balancing of copper, magnesium and zinc.

    Abstract: A method and apparatus for spin flow necking-in a D&I can (C) is disclosed wherein an externally located free spinning form roll (11) is moved radially inward and axially against the outside wall of the open end of a trimmed can (C). A spring-loaded (20) interior support slide roll (19') moves under the forming force of the form roll (11) as the latter slides along a conical forming surface (24e) of a second free roll (24) mounted axially inwardly adjacent the slide roll (19'). To prevent damage to the metal caused by excessive pressure contact between the form and slide rolls, the slide roll (19') is axially retracted via a cam ring (102) which initially contacts the form roll (11) during radially inward necking movement.
