Abstract: This disclosure relates to apparatus for making fluid flow connections. The apparatus comprises a tubular metal member having first and second ends. The first end is mechanically formed to the shape of one part of a two part quick-connect coupling, the one part being integrally formed on the first end of the member. The second end is mechanically formed to the shape of another fitting part which is also integral with the member. The portion of the member between the two ends is shaped to follow a desired path in order to interconnect other components.The one part of the quick-connect coupling preferably forms a tubular receptacle having an annular internal groove, a snap ring in the groove, and a relatively viscous fluid at least partially filling the groove around the ring.The disclosure also relates to a method of making and assembling apparatus as described.

Abstract: A connection assembly for joining two parts having confronting ends with a joint therebetween, particularly ceramic pipes, includes a dimensionally stable coupling member surrounding the joint and at least one of the two confronting ends of the two parts to be joined. The coupling member is dimensioned to define a space with the at least one part end. This space is filled with a ceramic fiber mat material containing a swelling agent capable of volume expansion when subjected to a temperature above a given minimum temperature. As a result, upon being subjected to an operating temperature above such given temperature, the swelling agent swells the ceramic fiber mat material, such that the mat material is compressed between the coupling member and the at least one part end surrounded thereby, thereby connecting the two parts.

Abstract: A locking assembly for securing the connection between a push-on fitting having a flared end fitted into a cage and surrounded by a garter-type coiled spring housed within the cage on a pipe having a plurality of O-rings sealing the connection between the push-on fitting and the pipe. The assembly comprises an axially split male fitting and an axially split locking nut. The two halves of the axially split male fitting are sized to snugly encircle the push-on fitting with the ends of the two halves of the male fitting resting against the flared end of the push-on fitting and thus forcing the coiled spring away from the push-on fitting. The two halves of the axially split locking nut snugly encircle the cage housing the coiled spring while an internal face of the two halves of the nut engage and securely lock the position of the two halves of the male fitting.

Abstract: The present invention relates to a weld joint for metal pipes. The object is to provide a weld joint which is easy to make and which has a clean surface inside the pipe. The ends of the pipes to be jointed are flared and a cylindrical metal sealing ring under axial compression is arranged between the inner conical flared surfaces of the flared pipe ends. The edges of the ring are elastically bent inward by the inner conical surfaces of the pipe ends. The sealing ring is preferredly provided with a circumferential flange projecting out between the pipe ends for facilitating correct position of the sealing ring.

Abstract: A flexible pipe coupling wherein an elastic sleeve has a centrally located annular internal partition which is contracted by the end faces of the end portions of two pipes which are inserted through the respective open ends of the sleeve. The sleeve has pairs of deformable annular sealing ribs which are disposed at opposite sides of the partition and engage the peripheral surfaces of the respective pipes. The ribs are separated from the partition by annular internal grooves of the sleeve, and the external surface of the sleeve has a centrally located outer groove for the circumferentially extending corrugations of a split ring having end portions provided with projections which can be moved toward each other by a bolt and nut to deform the ribs into sealing engagement with the respective pipes.

Abstract: A method and pipe connecting piece for connecting a pipe to a fluid port, such as another pipe. The pipe connecting piece has an end portion for insertion into the bore of a pipe-end, an intermediate portion of larger diameter than the end portion, an attachment means for attaching the connecting piece to a fluid port, and a sleeve.

Abstract: A detachable plug assembly for making a connection between a pipe and an external unit such as a hose fitting or hydraulic unit, for example, in which the pipe can be automatically locked in a well-defined axial position in a bore of the external unit, and thus be assembled in a short time on an assembly line, particularly in the case of assembly by robots, without requiring special tools for either assembly or disassembly. The assembly comprises a bushing which is mountable in a fixed axial position on the pipe, the bushing having a conical shoulder at a forward end thereof for axially engaging the bore of the external unit and centering the pipe therein. The external unit has slots through which project the free ends of a locking element. The free ends extend into the bore of the external unit and engage a groove in the bushing for retaining the pipe in the bore of the external unit.

Abstract: A pipe coupling assembly for plain end pipe of the type in which a packing ring is compressed in an internal groove by a thrust ring to squeeze it against the outer surface of the pipe and effect a seal therewith. The thrust ring is made of a plurality of accurate segments which can be economically produced and assembled in the coupling body. The segments are mechanically interlocked in the body by cooperation with other elements of the assembly to avoid separate retainer members. The segments have a configuration which avoids significant circumferential gaps in the packing compression face of the ring and reduces the necessary axial length of the groove.

Abstract: A device for convering rotary to linear motion is composed of at least one ring surrounding a shaft or tube with balls running in a part-helical track in the ring or shaft. The balls are radially pre-loaded and a slot intersects the end and the start of the track to provide punctiform ball contact zones. One ball is then transferred at a time free of load from the end to the start of the track as the ring rotates. Side covers have profiles on their inner surfaces to control laterally the ball being transferred.
