Patent GB-1301677-A (GB)
IPC: B22D11/04
Filed: 1969-12-31
Abstract: 1301677 Continuous casting; making wire; drawing W J BUEHLER 31 Dec 1969 [31 Dec 1968] 54299/69 Headings B3A B3F and B3P [Also in Division F4] TiNi base alloy, containing from 50-64% by weight of Ni as disclosed in Specification 1,020,872 and including TiNi base alloys in which Co is substituted for some of the Ni as described in Specification 1,202,404, is heated in an environment, e.g. a vacuum, inert to the alloy, in a graphite crucible 11, the molten alloy being forced through an orifice 14, 18 in the die while a metal body part 15 of the die, e.g. of Mo or W, is cooled so that a wire or ribbon is cast. The melt may be forced by a mechanical ram, the head of melt in the crucible or the introduction into the crucible 11 of gas such as Ar or He. A chamber surrounds the apparatus and is evacuated for the melting. A starter wire or ribbon 20a is inserted in the die 15 and in a bore in a die part 13 of the graphite crucible. The portion 13 may be a separate piece of anisotropic pyrolytic graphite and replaceable. The crucible 11 and die part 13 are heated by an inductor coil 70 and the part B around the part 13 is separately controlled according to the temperature monitored by a thermocouple in the portion. Another thermocouple in the crucible detects the melt temperature coil. The Ti and Ni &c. are melted, alloyed and cast, before placing in the crucible 11 for melting, or they are melted in the crucible or introduced as a molten charge. The precast may be of a shape to fit the crucible. To seal the bottom of the crucible before extruding, a skull of the alloy is allowed to solidify at the bottom of the crucible 11. It is melted by the coil part B before extrusion. To obtain light oxidation of the extruded product, it passes through air, oxygen or Ar or He (possibly mixed with oxygen) supplied to an aperture 63 in a pressure plate 62. The crucible 11 is held between the plate 62 and an upper plate 60 by springs 61. Drawing.-The solidified wire or ribbon (20) from the continuous extrusion is drawn through a succession of dies (41-45) and annealed between passes, e.g. by furnace heating in air, electric heating by slide contacts, induction heating, oxy-acetylene torch or immersion in a bath of Woods metal or fused salt, with a final annealing before storage. The area reduction for each pass is 10-20% and annealing is at temperatures below 800‹ C. Oxide is removed from the wire or ribbon by abrasion or acid bath; to render it non-magnetic it is pickled in the acid after drawing or annealed in Ar or He.

Filed: 1975-11-24
Abstract: 1519960 Manual and automatic control of throttle valve CHRYSLER UNITED KINGDOM Ltd 24 Nov 1975 [24 Dec 1974] 55849/74 Heading F1B An induction system for an I.C. engine comprises an induction passage 13 having a throttle valve 12, operator operable means 21, 15, 10 to adjust the valve and means responsive to air-pressure in the induction passage to reduce the throttle valve opening when the partial vacuum downstream of the throttle valve decreases. Acceleration pedal 21 is connected to the throttle valve 12 by way of a Bowden cable 15, 16 whose sheath 16 terminates in a sleeve 25 slidable within a hole 27 through a trunnion 28 in a lever 30 connected to a piston and cylinder assembly 35, 36 or a diaphragm assembly (not shown). When the engine is not operating the system is in the position shown and movement of pedal 21 is required to take up lost motion before a flange 26 on sleeve 25 abuts the trunnion 28. With the engine running and the throttle closed or nearly closed, the vacuum downstream of the throttle valve 12 causes the piston 35 to move downwards to rotate the lever 30 clockwise to take up the lost motion. As the pedal 21 is depressed to open the throttle valve 12, the manifold-vacuum falls and when it reaches a predetermined value the piston 35 moves upwardly to tend to move the throttle valve in its closing direction again. The cylinder 36 may be formed integrally with the inlet manifold 14. Instead of a cable operated mechanism, rods and linkages, pneumatic, hydraulic or electro-mechanical means may be used. Adjustable means may be incorporated in the arrangement to adjust the throttle restriction in response to the air-fuel mixture flow speed to obtain the desired vacuum in the inlet manifold.

Filed: 1972-12-08
Abstract: 1403059 Data processing INTERNATIONAL BUSINESS MACHINES CORP 8 Dec 1972 [30 Dec 1971] 56813/72 Heading G4A A digital data processor is programmed to analyse data representing two orthogonal views of a polyhedron to produce a representation of a further view of the polyhedron orthogonal to the two views, e.g. for use in manufacturing machine parts by numerical control. The front and profile view of the polyhedron are drawn, e.g. on a capacitance table in association with a known computer controlled graphics device. Then a list of the vertex points is formed and a list of lines connecting the vertex points. The list of lines is analysed to find sets of lines which form closed loops, i.e. polygons which are views of respective surfaces on the polyhedron. In addition there are also taken as polygon lines those which have vertical components. These lines can be flat surfaces which are seen in edge view in the given views, i.e. in the profile or front views. The polygons are sorted in order of decreasing altitude by finding the lines of constant altitude which pass across both the given views which gives a list of polygons that this constant altitude line crosses. When the number of polygons in the front view equal the number of polygons in the profile view the features can be immediately matched and the co-ordinates of the vertex points can be determined. When the numbers are not equal this signifies that a line has been dawn which is not the edge view of a flat surface and this line is deleted. The horizontal surfaces are then determined by consideration of the undefined vertex points. The further view is then determined from this data using a known program.

Title: Transducer steering mechanism
IPC: G11B5/596
Filed: 1968-11-29
Abstract: 1,219,598. Automatic position control. INTERNATIONAL BUSINESS MACHINES CORP. Nov.29, 1968 [Dec.21, 1967J, No.56887/68. Heading G3R. In a system for automatically maintaining a transducer on a record medium path bounded on each side by guide recordings having alternate long and short sections of different form, the short sections on each side being opposite long sections on the other, signals from the transducer are separated into components corresponding to each side and any difference utilized to steer the transducer. As described, a number of aluminium discs, coated with magnetic material, are mounted on a common shaft and associated with a number of record/ reproduce heads which are gauged together so as to be simultaneously movable in a radial direction relative to the discs by a servo-system to record or reproduce data along concentric circular tracks on the discs. One of the disc surfaces and its associated head is used to automatically control movement of all the heads so that they are maintained in register with selected tracks. The control disc, a portion of which is represented by Fig.2, has concentric tracks such as 35, 36, 37 with alternate long and short sections which are oppositely magnetized and staggered as odd and even tracks as shown. The control head 17 is automatically maintained on the dividing line between a pair of selected tracks as the disc rotates so that the other heads are located in corresponding positions. Head 17 produces pulse signals from each of the two adjacent tracks at the points where the sense of magnetization changes and, as shown in Fig.3, these pulses are integrated and rectified in opposite senses at 55, 56 sothat pulses of opposite polarity are produced for application through peak detectors 57, 58 to a comparator 60. If the head is central, the pulse amplitudes are equal and cancel but, if the head is displaced, comparator 60 produces a proportional output which is applied to the servo-system which restores the heads to their selected positions. A modified circuit involving single-shot multivibrators, diode, and transistor gating circuits for comparing the amplitudes of the pulse signals from the two tracks is described. For recording the control disc, an arrangement is described in which a clock disc, rotated with the control disc and operating in conjunction with a delay unit, times the recording sequence of the control tracks while a digital counter determines the lengths of the oppositely magnetized sections with the aid of logic circuits.

Filed: 1969-11-27
Abstract: 1287473 Planar transistors TELEFUNKEN PATENTVERWERTUNGS GmbH 27 Nov 1969 [27 Nov 1968] 58163/69 Heading H1K In the manufacture of a planar transistor both the emitter region 7 and the active base region 6 are formed by diffusion through the same mask aperture. The base contact 9 is provided on a base contact region 4 which is formed through an aperture adjacent that mentioned. Lateral diffusion ensures that the two parts of the base region meet or overlap. The two apertures are also used for the provision of the base 9 and emitter 8 contacts. The contact region 4 may be formed before, simultaneously with, or after the formation of the active base region 6 and both may be formed before or after the formation of the emitter region 7. The contact region is generally made deeper than the active base-the prior formation of the emitter region enables this result to be achieved even if both parts of the base region are formed simultaneously. If the two parts of the base region are first formed by separate diffusions, the base contact aperture is left open during the later emitter diffusion, it having been ensured that sufficiently heavy base doping is used in the contact region. In contrast to the figure shown, the base contact region may extend entirely around the active base region. Completion of the device may involve removal of the diffusion mask and the provision of new passivation. Details are given of further structural and processing variants.
