A manufacturing process for making different expansion tanks for different cooling systems and/or for different engines, each of the expansion tanks having an inlet mouth and comprising: a plastic shell comprising a) a wall defining a cavity for containing a coolant liquid; and b) at least one collar at the inlet mouth, the collar being outwardly projecting from the wall. Each of the expansion tanks further comprising a tubular insert engaging the collar and defining the inlet mouth; the tubular insert being made of plastic material; and retention means which hold the tubular insert relative to the collar. The process comprising making shells identical in shape and size, for all of the expansion tanks; and making inserts that differ in the value of their inner diameter; each inner diameter value being determined at the design stage depending on the type of cooling system and/or the type of engine.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. The pair of inner housing retaining surfaces can engage the pair of cooperating inner housing retaining surfaces, with the pin retaining receptacle of the inner housing extending into the interior of the outer housing, to slidably couple the inner housing and the outer housing together while permitting movement of the inner housing relative to the outer housing in a Y-direction in response to the inner housing moving in the Y-direction during insertion of the pin into the pin retaining receptacle. Associated methods are also disclosed.

An insulin infusion system is provided with a manual insertion device having a dual retraction spring (230) configuration for automatic introducer needle (222) retraction. A button (200) of the insertion device is used to insert the introducer needle (222) and catheter (202), and once the introducer needle (222) and catheter (202) have been fully inserted, a rotating engagement releases the dual retraction springs (230) such that the introducer needle (222) automatically retracts, leaving the catheter (202) in the body of the user. An end of the introducer needle (222) remains in the inserted catheter (202) and/or in the septum (206) of the inserted catheter (202) to provide an uninterrupted fluid path.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. A plurality of centering blades extend into the interior and between the inner and outer housings to locate the pin retaining receptacle in a central position within the interior in a Y-direction prior to insertion of the pin into the pin retention receptacle. The centering blades are movable in the Y-direction to permit the pin retaining receptacle of the inner housing to move to a non-central position relative to the housing in the Y-direction as a result of the inner housing moving the centering blades in response to the pin engaging the entry ramps during insertion of the pin into the pin receiving receptacle. Associated methods are also disclosed.

A method and an assembly installation for implementing the method automatically joining components, in particular of a motor vehicle-side radiator grill with a chrome frame, and/or a radiator grill of this type with a chrome strip, in an assembly installation. In a first step, a second component is positioned on a first component or a third component is positioned on the second component thus forming a complete component. In a second step, the complete component is placed in a horizontally-oriented component receiving device of the assembly installation and in a third step an installation-side stamping device is guided in the direction of the complete component in such a manner, in particular lowered vertically, that the complete component is influenced in an end position of the stamping device with a pressing force that provides a latching arrangement or pressing arrangement of the components.

A guide pin assembly for metal forming dies includes a cylindrical guide pin body with an external retainer groove adjacent one end thereof in which a retainer ring is received. An annular guide pin ring with an outside diameter greater than the pin body, has a counterbore adjacent the outside end thereof and a retainer groove in a medial portion thereof which receives the outer portion of the retainer ring to securely interconnect the pin body and the ring and thereby form an enlarged head at one end of the pin body which positively limits reciprocal motion between two associated die members. A circular guide pin head cap covers the outer end of the head ring, and includes a support collar that is closely received in the counterbore of the ring, and engages the retainer ring to securely hold the same in place.

An insulin infusion system is provided with a manual insertion device having a dual retraction spring (230) configuration for automatic introducer needle (222) retraction. A button (200) of the insertion device is used to insert the introducer needle (222) and catheter (202), and once the introducer needle (222) and catheter (202) have been fully inserted, a rotating engagement releases the dual retraction springs (230) such that the introducer needle (222) automatically retracts, leaving the catheter (202) in the body of the user. An end of the introducer needle (222) remains in the inserted catheter (202) and/or in the septum (206) of the inserted catheter (202) to provide an uninterrupted fluid path.

Disclosed is a method for producing a strip for fastening elements, said strip comprising a plurality of interconnected holders, each of which accommodates a shaft of a fastening element. The holders define a fastening direction in which the fastening element can be driven from the holder into a support by a fastening device. The disclosed method comprises the following steps: a) producing a continuous strip defining a longitudinal direction of the strip; b) making the holders from the strip material by means of a deep-drawing process; c) accommodating the fastening elements in the holders.

A method of manufacturing a packing cup for a hyper-compressor is described. The method comprises the following steps: providing an inner disc (25), having opposed first front face (25X) and second front face (25Y), a central axial hole (18) and at least one lubrication-oil duct (23); autofrettaging the lubrication-oil duct (23); after autofrettaging, removing a thickness (D) of the inner disc on both faces thereof.

An expansion tank for a cooling system of a motor vehicle has an inlet mouth and is provided with a shell in plastic material having a wall which defines a cavity for containing a coolant liquid; the shell has, in addition, a projecting collar, at the inlet mouth, and a first inner tubular wall, which protrudes downwards into the cavity and defines a passage with a lower outlet opening, to make the coolant liquid flow into the cavity; the shell has, in addition, a second tubular wall, projecting upwards into the cavity and defining a compartment which is vertically aligned with the passage and has an upper overflow opening vertically arranged at a height that is equal to or greater than that of the outlet opening.
