Title: Improvements in or relating to driving centres for machine tools
IPC: B23B33/00
Filed: 1953-08-04
Abstract: 740,850. Lathe and like centres and drivers. KOSTYRKA, T. A. Aug. 4, 1953 [Aug. 4, 1952; April 4, 1953], No. 21464/53. Class 83 (3). A driving centre for machine tools, comprises a body 2, Fig. 3, in which a centre 3 is slidable axially against a spring 4, plungers 7 in bores surrounding the centre 3 engaging, at their inner ends, balls 6 in an annular recess 5. The plungers support a disc 12 retained to the body by a cap 14 and having teeth 21 engageable with the end face of a work-piece supported by the centre. Movement of each plunger is limited by a pin and slot. In fixing work between centres, the tailstock is advanced to cause centre 3 to compress spring 4 until the end face is engaged by the teeth. The movement is continued until the plungers cause the balls to engage a shoulder 19 on the centre, thereby preventing further movement of the centre. The disc 12 may be integral with the teeth, in which case several discs are provided for work of different diameters and for rotation in opposite directions, or provided with radial grooves in which separate teeth are slidable to various positions. In another arrangement, the plungers 7, Fig. 10, have teeth 25 and may be oval with teeth 25, 25<SP>1</SP>, Fig. 11, to cope with differing diameter work. The plungers may be turned through 180 degrees for rotation of the centre in the opposite direction.

Abstract: 1517253 Mixing apparatus HERMANN BERSTORFF MASCHINENBAU GmbH 26 May 1976 [30 May 1975 25 March 1976 (3)]21885/76 Heading BIC Apparatus for the continuous processing of a moulding compound (e.g. in powder form) of synthetic plastic or rubber comprises a channel member 13 having a transverse or oblique undulating profile and a member 26 having a cooperating profile and driven by synchronised cranks 17, 18 so that its valleys and peaks 32, 42 perform a circular motion in relation to the respective valleys and peaks 33 of the member 13; the material is thus compressed and sheared and conveyed through the apparatus. The undulations of the two members are of the same pitch; as shown the peaks and valleys of the member 26 are circles of radius r 0  joined by tangents, while the valleys of the member 13 are circles of radius r 0  plus the crank radius, the peaks being formed by suitable rounding-off. The clearance between the two members may be altered by adjusting the lengths of the connecting rods 24, 25. The members may be in the form of strips with the profiles of the adjacent strips staggered, and their undulations may be oppositely inclined (see Figs. 7 and 8, not shown); the strips of the member 26 may be separately driven. The profiles of either or both members may become shallower or flat at the inlet or discharge end (see Figs. 9-13, not shown); the apparatus may be downwardly inclined towards the discharge end (Fig. 10); the volume between the members may increase at either end and the flattened end of the member 13 may be pivotted to vary it (see Fig. 11). Either member may be resiliently loaded to yield along or at right angles to the longitudinal axis to relieve excess pressure (see Figs. 14-16 not shown). The temperature of either member may be controlled.

The driving disc rim 17 is grooved t'o receive, radially-acting jaws 16 carried by the driven disc and controlled by levers 18 which are pivoted at 19 on the driven disc and carry pins 20 acting through links 21 on the ends of adjacent jaws. Rollers 23 on the ends of the levers are forced inward or outward to disengage or engage the clutch by expanding and contracting bands 25, 24 controlled by levers 26<1>, 26 actuated by cords 30, 30<1>. To engage the clutch at starting and at low speeds the band 24 is expanded and the jaws forced outwards to engage the rim 17. At high speeds the jaws are engaged with the rim by centrifugal force. To disengage the clutch the band 25 is contracted to force the jaws inward. The clutch may be cooled by water directed by a stationary nozzle into a channel leading to a chamber formed in the rim 17, the water passing from the chamber over the gripping surfaces and escaping either as water or as steam.

Abstract: 1529518 Semiconductor devices NATIONAL SEMICONDUCTOR CORP 28 May 1976 [2 June 1975] 22358/76 Heading H1K [Also in Division B3] In gang thermo-compression bonding of leads 16 to bumps 21 on a semi-conductor chip 22 and a lead frame 43, the bonding surfaces of the bumps, lead frame or the chip-bump-bonding or lead-frame-bonding surfaces of the leads are of Cu and are antioxidant coated at 41 to a thickness, and with a material, compatible with thermo-compression bonding therethrough. The coatings 41 may be of gold applied to a thickness less than 6000 angstroms by immersion, chromate applied to a thickness of 10-100 angstroms by HCl cleaning, plating in 2% chromic acid, 8% full strength H 2 SO 4 , 90% deionized water and rinsing in deionized water and drying, or copper phosphate applied to a thickness of 100-2000 angstroms by HCl cleaning, rinsing in deionized water, oxidizing in air, immersion in 84% phosphoric acid solution and rinsing in deionized water and drying. As particularly described, the leads 16 are initially formed, in a pattern 14 from a wrought Cu foil tape 11 (Fig. 1, not shown) provided with transport sprocket perforations (13). A polyimide film 15 positions the leads in their pattern, and perforations 19 facilitate subsequent foil shearing. The chip 22 comprises a semi-conductive substrate 23, a grown epitaxial n-type layer 24, p+ and n+ regions 25, 26 diffused into the layer 24, a first passivation layer 27 of SiO 2 , a metal pattern 28, e.g. Al, in electrical contact with the regions 25, 26 by way of first passivation layer apertures 29, gang bonding bumps 21, deposited, e.g. electroplated, over and in contact with the pattern 28, and a second passivation layer 31, e.g. of SiO 2 . The chip is initially carried, with others, on a glass plate (Fig. 3, not shown) by way of wax and films (35, 34) and a layer of release wax (36), adjacent chips being separated by part-way saw cuts (37). At a lead-chip bonding machine (Fig. 3, not shown), the chip 22 and the pattern 14 of leads 16 are registered with a gang bonding tool 38, e.g. beryllia ceramic, heated, e.g. to 550 C., which tool presses the inner ends of the leads 16 on to the bumps 21 at approx. 8 grams/square mil for approx. 0À2 seconds. The bond is thereby effected, and due to heating, the wax (36) releases the chip. The tape 11 with attached chips is then fed through a further machine which thermocompression bonds the outer ends of the leads 16 to lead frame members (43, Fig. 6, not shown) of Cu or substrates thickly plated with Cu. A lead frame/lead bonding tool (46), e.g. at 450 C., is pressed against the underside of the leads, e.g. at 10-30 grams/square mil for approx. 0-15 seconds, and the lead pattern 14 is peripherally sheared from the tape 11. Finally the lead frames are moulded epoxy packaged (Fig. 5, not shown).
