Title: Sputter deposition on an irregular surface
IPC: C23C14/35
Filed: 1969-07-02
Abstract: 1,269,408. RF sputtering. INTERNATIONAL BUSINESS MACHINES CORP. July 2, 1969 [July 3, 1968], No.33300/69. Heading C7F. A dielectric film is sputtered on to a substrate having a raised metallic line by disposing said substrate in a partially evacuated chamber containing inert gas, applying RF voltage between a dielectric target and the substrate to sputter the target, inducing a negative potential of at least 60‹ volts on the surface of the dielectric as it is deposited, and maintaining said potential to produce a film of thickness at least 1000Š greater than the metallic line. Said negative potential may be induced by (1) applying a magnetic field perpendicular to the substrate surface and controlling the inert gas pressure relative to the magnetic field strength and input power or (2) connecting an impedance between the substrate holder and a conductive surface in the chamber which is RF coupled to the target. The substrate may be an integrated circuit, e.g. a Si wafer having raised Mo lines; the dielectric may be silicon dioxide or nitride or Al 2 O 3 ; the inert gas may be Ar.

Abstract: 1411541 Micro-fiche card printing SEACO COMPUTER DISPLAY Inc 13 Oct 1972 [15 July 1971] 33325/71 Heading G2A Framelets of micro-fiche frames are printed in longitudinal and transverse step-and-repeat manner on film which is advanced between loop-forming rollers 30/31 and 32/33 without corresponding movement of pay out and take up reels 28 and 34. Longitudinal framelet rows of a frame are printed by forward and return movement of the film 27 and clamped film gate 18 using motors 37 (driving pairs of rollers 31 and 32) and 23 (driving the gate), transverse movement of the whole assembly of reels, loop-forming rollers, gate and motors being effected on the return movement by motor 16. After the printing of a complete frame (the loops being in the broken line position), motor 36 drives pairs of rollers 30 and 33 (drawing film from reel 28 to reform loop 27a and winding film on reel 34 to reduce loop 27b) and gate 18 is repositioned relative to the film for the printing of a further frame. The number of separate motors may be reduced by clutch arrangements. Further, the drive from either of motors 23 and 37 could be dispensed with. Further, a servomotor having a resettable feedback position sensing means could be employed. In another embodiment (Fig. 3), the film is passed vertically downwards through a gate which is fixed (unclamped) and narrow (corresponding to a single transverse row of framelets).
Patent GB-333690-A (GB)
Abstract: 333,690. Willigen, P. C. van der. Nov. 6, 1928, [Convention date]. Adhesives comprising stable aqueous or other emulsions of oxidised drying oils or varnishes or lacquers containing such oils, are prepared by oxidising emulsions of drying oils in the presence of (1) caustic alkali or ammonia, added in successive quantities during the reaction to keep the emulsion alkaline, or (2) buffer substances such as soaps or salts of strong bases and weak acids, e.g. sodium, potassium or ammonium carbonate, or (3) a combination of (1) and (2). The oxidation may be effected by blowing in oxygen or oxygen-containing gases such as air, or by spraying the emulsion into such gases. Increase in temperature and pressure facilitates the reaction, the optimum temperature being between 30‹ C. and 70‹ C. Examples of the invention are as follows-(1) Air in finely divided condition is blown through an emulsion at 50‹ C. containing 150 Kg. tung oil with siccatives and 1000 Kg. of about 0.2 normal sodium oleate solution. (2) 150 Kg. of lacquer containing boiled oil, resin and kauri copal are mixed with 850 Kg. 0.3 normal sodium carbonate solution and emulsified therein bv blowing gas through the mixture. Oxygen is then led through at about 50‹ C. for 12 hours. The product may be employed in the process of Specification 301,901, [Class 140, Waterproof &c. fabrics]. (3) The process of (2) may be modified by emulsifying originally with a quantity of 0.1 normal solution of caustic alkali and adding a sufficient quantity of a similar solution at hourly intervals to prevent the mixture from becoming acid. Specifications 318,562 and 321,692, [both in Class 91, Oils &c.], also are referred to.

Title: Improvements in and relating to ribbon carrier for typewriters and like machines
IPC: B41J35/04
Filed: 1956-11-01
Abstract: 800,968. Ink-ribbon mechanism. ROYAL McBEE' CORPORATION. Nov. 1, 1956 [Feb. 28, 1956], No. 33436/56. Class 100(4) An ink-ribbon carrier has eyes that can be quickly opened with one hand for ribbon changing and are automatically closed by abutting against stops as the carrier rises when a key is struck. Movable arms 25, Fig. 4, are pushed towards each other by pinching finger pieces 27 between finger and thumb, when ink-ribbon 24 may be inserted. Depressing any type key 10, Fig. 1, causes the ink-ribbon carrier 16 to be lifted into printing position through conventional linkages 17. The height to which the ribbon is raised depends on the setting of the ribbon control lever 18. As the carrier 16, Fig. 4, is raised, lugs 31 of arms 25 abut on parts 34 of fixed stops 32 causing arms 25 to move into a vertical position to close the eyes. Lugs 35 of stops 32 prevent the eyes being opened with the carrier in raised position. Stops 32 may be combined in one piece, Fig. 6. Spring 28, Fig. 4, holds arms 25 in either open or closed positions. U.S.A. Specification 2,509,862 is referred to.

Title: Methods and apparatus for processing well logging data
IPC: G01V1/50
Filed: 1970-07-09
Abstract: 1322795 Data processing SCHLUMBERGER INLAND SERVICES Inc 9 July 1970 [14 July 1969] 33439/70 Heading G4A Signals representing measured characteristics of an earth formation traversed by a borehole are used to compute first electrical signals representing the proportions of different formation parameters (e.g. rock types) in a first selected set, the proportions are tested for feasibility, and if found not feasible the measurement signals are used to compute second electrical signals representing the proportions of different formation parameters in a second selected set. The process is repeated until a feasible set of parameters is arrived at. A general purpose digital computer may be programmed to perform the required computations. Figures 1A and 1B show borehole logging devices 13-15 providing signals #t, #N, Pb representing measured values of acoustic travel time, neutron derived porosity and bulk density. A discriminator 45 determines whether or not a given characteristic (e.g. spontaneous potential) exceeds a predetermined threshold and accordingly selects a first or second group of matrix computers 1-4 or 5-n which corresponds to groups of sets of formation parameters. If group 1-4 is selected, the measurement signals are supplied to the first matrix computer which derives signals representing the percentages of the bulk volume of the four selected parameters in the corresponding set. A feasibility test circuit comprising a detector 50 which checks that none of the computed percentages is negative, a discriminator 52 which checks that one parameter, e.g. waterfilled porosity, is above a given level, and an AND gate 51 provides a signal to enable gates 49 to record the computed percentages if they are feasible, and at the same time, via generators 40, provides a signal identifying which matrix provided the recorded results. If the first matrix computer does not produce feasible results, counter 27 is stepped on to select the second matrix computer, and selection of successive computers is continued until a feasible result is obtained when counter 27 is reset ready for the operation to be repeated at the next depth level indicated by a pulse generator 29. Matrix computer 3 may however be by-passed if a discriminator 56 determines that the set of parameters corresponding to the fourth matrix computer is more probable than that corresponding to the third computer. Operation of the system when the second group of computers is selected is similar except that counter 27 starts at stage 5.

Patent GB-635318-A (GB)
Title: Process for the manufacture of refined aluminium
Filed: 1947-12-19
Abstract: A process for the manufacture of refined aluminium from raw materials containing aluminium metal together with other elements comprises preparing a salt melt containing an aluminium trihalide, e.g., the trichloride, contacting this melt with the raw material, e.g., at a temperature of above 300 DEG C or near or even above the melting point of aluminium, thereby causing an aluminium subhalide to be formed by reaction between aluminium and aluminium trihalide, removing the melt from contact with the raw material and lowering the temperature to cause separation of aluminium metal.  Aluminium may be separated in solid form while the melt remains fluid.  The melt may contain also a halide of an alkali metal or an alkaline earth metal. The materials treated may be commercial aluminium or aluminium alloys or aluminium scrap.

Title: Improvements in and relating to the manufacture of concrete building blocks and units
IPC: B28B7/32
Filed: 1936-12-08
Abstract: 486,452. Moulding concrete building- slabs. RUEGG, A. E. Dec. 8, 1936, No. 33688. [Class 87 (ii)] [Also in Group X] In moulding reinforced concrete blocks, the concrete is vibrated and subjected to vacuum and gradually raised to an elevated pressure which is finally reduced to normal atmospheric condition. The blocks A preferably have tongued and grooved ends C, D and central cavities B to reduce weight. They may also be formed with window or door openings. The mould is formed of side members 10, top and bottom members 13, 14, and end members 12. The side members 10 are formed with two walls 38, 39 connected by metal struts to withstand pressure and are connected by bolts. The end members 12 are clamped to the members 10 by clamps 42. Wedge-shaped keys 15 hold the mould rigid. End sections 11 for forming the tongues and grooves are formed in a number of pieces for easy removal. The bottom 14 has transverse slots 28 to receive loops of the reinforcing steel E, the slots being afterwards filled by fillets held in place by a longitudinal key bar. The steel E may protrude through holes in the top sealed by conical rubber sleeves. Hollow rubber cores 32 are positioned in the mould by spacers 34 and pins 44. The top of the mould has a pressure manifold containing ducts 36 leading to the cores. In operation, the mould is assembled, the steel E is subjected to an initial tension, and the concrete is poured in. The mould is next vibrated and the concrete is subjected to vacuum through ducts in the top manifold. The cores 32 are then gradually expanded by fluid pressure which rises to 5,000 1b. per sq. in. while the temperature is raised to 300‹ F. by hot air in the cores. The pressure and temperature are finally slowly reduced to normal and the mould is dismantled. The whole process is preferably performed as the moulds pass along a trackway.
Patent GB-618709-A (GB)
Title: Improvements in and relating to dynamo electric machines
IPC: H02K23/02
Filed: 1946-11-13
Abstract: 618,709. Exciting dynamo-electric machines. HILL, E. P., and METROPOLITAN. VICKERS ELECTRICAL CO., Ltd. Nov. 13, 1946, No. 33711. [Class 35] In a generator whose output voltage is required to vary in linear relationship with the current in a controlling field winding, the drooping effect of the saturation of the generator field is offset by boosting with a shunt field winding connected through a non-linear resistance. This resistance is composed of material known under the Registered Trade Mark " Metrosil," which allows a disproportionate current to flow in the shunt field winding for high voltages. In the form shown in Fig. 1, the separately excited field winding 2 of a generator 1 is boosted by a shunt field winding 3 connected in series with a non-linear resistance 4. In another form (Fig. 4) the shunt field winding 3 and controlling winding 2 act on an exciter 5 which in turn energizes the main generator 1. This exciter which may be a metadyne or armature-reaction type of machine, may have several controlling windings so that the generator output is governed by a combination of factors. An arrangement is shown in which the shunt winding is used to limit the generator output or other quantity, by means of a relay which reverses its polarity so that it bucks the separately excited winding at a predetermined value of armature current. In a further modification, the response of the generator to the controlling field is quickened by connecting this field winding in series with the secondary of a transformer whose primary carries the generator armature current. Specification 574,155 is referred to.

Title: Automatic adjusting device for brakes
IPC: F16D65/56
Filed: 1963-08-26
Abstract: 971,327. Automatic brake adjustments. D.B.A. S.A. Aug. 26, 1963 [Sept. 4, 1962], No. 33759/63. Heading F2E. A brake comprises a rotatable friction surface 10 against which a friction member (12 or 14) pivoted on a fixed support is applied by a lever (28 or 30) through a screw-and-nut assembly (see Fig. 2), the length of which is varied automatically if the lever rotates in excess of a predetermined angle by a rotatable member 70 which is operationally connected to the lever at 74 arid which transmits its movement to the screw-and-nut 54, 56 through a frictional coupling 72 which can only transmit rotation when the screw-and-nut is not loaded by the brake-applying force so that adjustment only takes place in a direction corresponding to lengthening the assembly upon the return movement of the lever to its unactuated position. One end of each of the webs 16 of the brakeshoes 12, 14 are retained in a slot in the end of the screw 54 by a spring 38 or 40 and the other end of each in a slot in one of a pair of non- adjustable levers 26 or 32 where they are retained by a spring 42 or 44. Springs 46 and 48 hold the sets of levers at the adjacent ends of the shoes against abutments 50 and 52 which are bent up from the supporting back-plate 36. In the screw-and-nut assembly the nut 56 is threaded on the screw 54 and bottoms on a shoulder 60 in a recess in the lever (28 or 30). It is rotated to adjust the protruding length of the screw 54 by a toothed wheel 62 which meshes with the toothed wheel 64 against which the surface of another toothed wheel 70 is pressed by the dished springs 72 to act as a friction clutch. The wheel 70 meshes with a sector 74 journalled on the reduced diameter end of the pin 34 and retained by a snap-ring 78. The sector 74 has two tabs on its lower face which are located in axial grooves 82 formed in the pin 34. The grooves 82 are circumferentially oversize and allow the sector 74 to turn an amount corresponding to the normal travel of the lever when the brake is applied. If, due to wear, excessive travel occurs the tabs will abut the sides of the grooves 82 during the last part of the travel, holding the sector stationary whilst the lever is still moving and thereby causing the pinion 70 to drive the tooth wheel 64 on the return movement of the lever. The adjusting device on the lever 30 is exactly similar to that on the lever 28.

Abstract: 788,203. Blast furnaces. KO-WE NIEDERSCHACHTOFEN GES. Nov. 25, 1955, No. 33849/55. Class 51 (2). [Also in Group XXIX] In a blast furnace operated by a number of tuyeres, sudden increase of the blast through a particular tuyere near a " blow-through " in the charge, is prevented by introducing an automatically operated valve between the bustle pipe and each tuyere. The valve 3 operates in a housing 1 formed in a pipe 9 leading to a tuyere, and the stem 5 is loaded by a spring 7, the pressure of which is adjustable through a screw 8. A sudden rush of air through the pipe 9 will move the valve 3 towards its seating 2, reducing the supply to the tuyeres and preventing enlargement of the " blow-through " cavity. The phenomena can also be controlled by fitting a gate valve before each tuyere measuring the blast through a tuyere, and arranging for the pointer of a blast indicator to close an electrical switch when it reaches an adjustable maximum value, thus energizing an electric motor to close the gate valve to an adjustable minimum opening. The motor is arranged to re-open the valve at an adjustable, slow speed.
