IPC: B02C18/10
Filed: 1968-04-24
Abstract: 1,265,316. Comminuting apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. 23 April, 1969 [24 April, 1968], No. 19432/68. Heading B2A. [Also in Division A4] A comminuting machine comprises a container 1 for a liquid media for carrying the material, e.g. silage, to be chopped, a stator 8 and a rotor 9 both within the container and each carrying a plurality of straight cutting edges, and means for causing flow of the liquid and material in the direction generally parallel to the rotor axis to a space between the cutting edges and this axis and then in a generally radial direction away from the axis to the region between the stator and rotor cutting edges; each cutting edge being spaced from the axis, disposed in an imaginary surface generated by rotation about the axis of a line intersecting the axis, the surface preferably being a plane at right angles to the axis, and inclined at an angle to a radius intersecting that edge, the rotor cutting edges being inclined at an angle to and intersecting the cutting edge of the stator with which it temporarily cooperates. Each cutting edge is one edge of a copying lathe cutter tool of equilateral triangular-section prism shape. The rotor is disc-shaped and has wire cutters 30 secured to a reduced thickness outer annulus 28, the leading edges (55), Fig. 3 (not shown) being the cutting edges. A trailing vertical corner edge of each cutter abuts against a shoulder (29), Fig. 3 to prevent rotation of the cutter about its fixing stud (31). The stator has four cutters (17), Fig. 3 secured to spider arm parts 10. Two vertical corner edges of each cutter 17 engage a skirt 11 of stator 8 to prevent their rotation. The rotor is secured to a shaft 24 rotating within a tube 19, held stationary by a clamp external to container 1, and the stator 8 has a square centre hole slidingly fitting over a square spigot 18 on the lower end of tube 19, a spring 35 around spigot 18 urging stator 8 towards rotor 9. Turbulence of the liquid media caused by rotation of rotor 9 causes recirculation of the material between the cutters, vanes (38) on a shield (37), Fig. 2 (not shown) wound spigot 18, and vanes 39 on container 1 directing the liquid axially downwards and vanes (36) Fig. 3, on rotor 9 then directing the liquid outwards between the cutters. Material is fed into container 1, previously filled with liquid, e.g. water, to at least cover stator 8, through a hopper 45 in a top closure 6, sealed by a C-ring (40), Fig. 2, and held in position by two bars 41 engaging in holes (52) and L- shaped retaining slots (42), Fig. 2, in an upper skirt 5 of container 1.

Abstract: 1,266,784. Felt for papermaking machines. J. J. MARX G.m.b.H. 11 March, 1969 [2 April, 1968], No. 12638/69. Headings D1R and D2A. A wet or dry felt band has grooves which extend transversely of the band, and substantially at right angles to its longitudinal axis formed in the band itself by thermal or chemical treatment of the strip. The grooves may consist of a plurality of part-grooves which do not extend across the width of the strip. These may be offset relative to one another. The grooves may be provided on both sides of the strip. Used, creased felts may be used again after such grooving. The form, depth and spacing of the grooves depend on the requirements of use, e.g. angle of wrap of rollers, the pressure the felt is to be subjected to in press nips, the required rigidity and the required permeability or thickness.

Abstract: 1288564 Semi-conductor devices NATIONAL RESEARCH DEVELOPMENT CORP 27 Jan 1970 [24 Jan 1969] 4296/69 Heading H1K The contact system for a flip-chip semiconductor device includes a film which connects contacts on semi-conductor regions to raised bonding pips. A lower chromium layer in the film adheres well to passivation on the semiconductor and merges with an upper, gold layer which carries the bulk of the operating current of the device. The section of Fig. 7B is along line AB of Fig. 8 and does not show the enhanced conductivity region and contact 6 associated with the collector region of the illustrated transistor. The silicon planar has silicon oxide or double layer silicon oxide-silicon nitride passivation 3 through apertures in which contact is made to the silicon by metal layers 16 of aluminium or of molybdenum. The superposed layers of the film are deposited overall, and the gold layer then etched to the shapes 7, 8, 9 of the interconnection pattern with a solution of I 2 /KI. The bonding pips 11 are then formed by electroplating and as shown consist of a main body of silver with a further deposit 12 of tin to act as a solder when the transistor is bonded to a substrate. The chromium layer 13 is then also selectively etched to the shape of the interconnection pattern using a solution of NaOH/ KMnO 4 . During processing the chromium and gold layers are partially merged by a sintering step at 200-300‹ C. Alternative metals for the conductor pips are nickel, lead, copper, gold (when thermocompression bonding is to be used) and uncoated silver (when ultrasonic bonding is to be used). Devices in integrated circuits may have some conductive pips in common. Further conductive pips, not acting as contacts, may be present to give mechanical stability to a devicesubstrate assembly.

Abstract: 1296069 Controlling oxygen steelmaking NIPPON STEEL CORP 29 Dec 1969 [27 Dec 1968] 63007/69 Heading C7D The exhaust gas from the converter is drawn by a fan through a conduit in which is a flow control device acting to bring the flow of gas and inducted air into conformity with a predetermined relationship with time based on previous experience with heats blown under similar conditions. In this way the carbon content of the steel in the final stages of blowing can be determined from measurements on the exhaust gas. Preferably the gas flow is given by α(t). Fo 2 . K., where Fo 2  is the oxygen flow and α(t), K are previously determined coefficients, which may vary during the course of the blow. 'The carbon content of the bath is obtained by determining decarburization velocity from the composition and flow volume of the exhaust gases. As particularly described, oxygen flow meter 16 sends a signal to multiplier 10 wherein are stored the coefficient values, and the subsequent output passes to controller 9, which also receives a signal from exhaust gas flow meter 13 corrected for temperature and pressure at 13<SP>1</SP>; on the basis of this information damper 4 is operated by cylinder 7 under control of regulator 8. Flow volume and gas analysis are integrated at 19 to give decarburization rate.
