Title: Thrust bearings
IPC: F16C19/30
Filed: 1975-09-12
Abstract: 1474349 Bearings TORRINGTON CO 12 Sept 1975 [16 Sept 1974] 37507/75 Heading F2A A thrust race (Fig. 4) comprises a member having a substantially circular outside periphery with an axially extending outer flange 28, the flange having circumferentially spaced pairs of cut-outs 16.

Title: Wire bonding apparatus
IPC: H01L21/60
Filed: 1975-09-12
Abstract: 1467208 Welding by pressure HITACHI Ltd 12 Sept 1975 [13 Sept 1974] 37678/75 Heading B3R In apparatus for wire bonding comprising means to receive a wire supply (e.g. a spool 2 on a shaft 3), a feed capillary 6 for holding the wire 1, and a wire tensioning means 8 between the wire supply receiving means and the capillary, the tensioning means comprises an orifice 9 for directing a gas jet between two guide members 11, 12 to impinge on the wire. The apparatus also includes a wire clamp 7 and a back tensioning means (i.e. air blown on the spool 2 in a direction 4). In operation, a hydrogen flame 14 forms, by melting, a ball 15 at the end of the wire. The clamp 7 is released and the wire is pulled upwards so that the ball 15 abuts the base of the capillary 6. The capillary is then lowered to press the ball 15 on to a first bonding point 18, raised, and then moved horizontally to a position above a second bonding point 20, thereby drawing from the spool a length of wire l 0 +α (l 0  being the length of loop required between two bonding points). As the capillary is lowered toward the second point 20 the wire is pulled in to the capillary by the length α. The clamp 7 then secures the wire 1 and the capillary 6 and the clamp 7 are raised after cutting the wire. The air jet provides a constant wire tension and, by accommodating wire deformation (to the chain-lined curve 22) on rapid displacement of the capillary, minimizes the risk of wire breakage.

In the apparatus shown in Fig. 1, sodium or potassium silicate is supplied through pipe 3, aluminium sulphate through pipe 5 and water through pipe 4. A core 10 having helical grooves 12 and with its base in the pipe 4 causes the water to emerge as a rotating annular curtain, the pressure drop in zone A causing high shear; a helical baffle 13 then reverses the direction of rotation with turbulent mixing. Hydrochloric acid may be introduced through a pipe 14. The apparatus may discharge directly to a liquid to be treated, or may be discharged by a hydraulic ejector (16, Fig. 2 not shown) providing additional dilution and pressure below atmospheric by at least 10 m. Hg. Additionally or alternatively to the core 10 there may be in the mixing tube a helix formed of twisted sheet metal which may also be cut perpendicular to its axis to form various arrangements of vanes (see Figs. 4-8, not shown).
