In a method and apparatus for soldering or tinning wires or component leads, solder is pumped through a nozzle to form a downwardly flowing stream. The wire or lead is passed laterally into the stream and then withdrawn axially to leave a coating of solder on the wire. The wire or lead is angled to the horizontal, pointing upwardly in the direction of withdrawal from the stream.

Structure for screwing on sheet metal an object having a fitting hole comprises sheet metal having a prepared hole formed therein in the shape of a saucer and also having a saucer-shaped lip which has a thickness equal to the thickness of the sheet metal and defines the prepared hole, and a screw composed of a screwhead, a shank depending from the screwhead, external threads formed around the shan...

The liner used in the combustor and other components is fabricated from a cylindrical shell and segmented panels attached to the shell. The attachment includes a self-locking nut and flexible bushing mounted on a post extending from the panel to protrude through a hole formed in a shell, thus permitting assembly in a limited space.

A roll for use in a calender has a stationary carrier which is surrounded by a hollow cylindrical shell with the interposition of a hydraulically operated displacing unit which can flex selected portions of the shell when necessary so as to establish a preselected nip between the peripheral surface of the shell and the shell of an adjoining roll. The hydrostatic displacing unit is flanked by two a...

CONSTITUTION:Oil flows into the other hand chamber 30 divided by fitted parts through cast pierced holes 12', and fills in the same chamber. Since slits 50 are provid...

A fluid friction clutch, suitable especially for a cooling fan of an internal combustion engine, has a shear gap of substantially serpentine form seen in axial longitudinal section, which is formed by concentric annular ribs. The ribs of the two parts which form the shear gap engage in each case in concentric annular grooves between radially adjacent ribs of the other part. The ribs have conical r...
