Title: Pneumatic or hydraulic delay device
Inventor: RONA JANOS
IPC: G06D1/04
Filed: 1964-01-21
Abstract: 1,059,792. Fluid delay elements. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Jan. 21, 1964 [Jan. 22, 1963], No. 37569/66. Divided out of 1,059,791. Heading G4P. A delay device which may be used to delay the carry in the binary adder of Specification 1,059,791 comprises a slide valve 15 (Fig. 4) moved, when a high-pressure pulse representing the digit " 1 " is applied to input channel 14b, to bring a source of high pressure into communication with a channel 17. As the pressure increases at the end of a capillary tube 22, a further slide valve 18 is moved after a time delay to the position "shown in dotted lines so that a high-pressure source at 18a is applied to the output channel 12a. Similarly a slide valve 19 is moved to the right so that output channel 12a is in communication with the left side of valve 18 and consequently secures the high pressure signal which also serves to keep valve 18 in its right-hand position. If a " 0 " signal succeeds the " 1 " signal, the input 17 of the delay element is vented and the pressures at 22a, 23a gradually decrease so that valve 19 moves to the left masking the port between tube 22a and outlet 12a. After a fixed time delay the pressure at 22a drops sufficiently to allow valve 18 to resume its left-hand position.

Abstract: 1,112,155. Circuit assemblies. FUJITSU Ltd. 2 Sept., 1965 [2 Sept., 1964], No. 37628/65. Heading H1R. In a microelectronic assembly, active elements are mounted on a first plate and passive elements are mounted on a second plate, the two plates being subsequently joined by fusion. Fig. 1 shows a first plate 1 of glass, ceramic &c., comprising a base part la and an integral peripheral flange 1b. Flat conductors 2 are sealed through the flange during the construction of plate 1, and on some of these conductors are disposed active elements 3 such as transistors, diodes etc.; internal connections are made by fine wires 4, and conductive fusible contact layers 5 extending from conductors 2 are deposited on to the upper surface of flange 1b. Fig. 2 shows a second plate 11, of similar material to that of plate 1, on which are disposed passive thin film elements such as resistors 12, capacitor 13, wiring 14, and conductive fusible contact layers 15, which register with corresponding layers 5 on the first plate 1 when the two plates are placed together (Fig. 3a, not shown), with layers 5 and 15 in mutual contact, and a fusible substance (7) such as low melting- point glass, is interposed between flange 1b and plate 11, and heated to unite the plates. Modifications.-In place of deposited layers 5, metal connection strips may run from conductors 2 on to flange 1b for fusion with layers 15 (Fig. 3b, not shown), and the ends of such strips may be turned back to form resilient portions on the flange (Fig. 3c, not shown); alternatively, conductors 2 may be bifurcated inside flange 1b, one leg of the bifurcated portion being turned back on to the flange (Figs. 3d-3f, not shown). In Figs. 3g, 3h (not shown), the flange (9) is located on the first plate (1A) a distance in from the periphery, and the plate (1A) carries active elements 3, the fusible substance (8) being interposed between the plates outside the flange when the assembly is mounted in a furnace (Fig. 6, not shown), between two heat-conducting blocks (21a, 21b). In Fig. 4 (not shown), conductive studs welded to conductors 2 extend upwards through the flange on plate 1, to form bases for fusible layers. Conductors 2 may be disposed at all four sides of a rectangular assembly. The planform of the assembly may be circular or elliptical.

Abstract: 1,113,094. Controlling change-speed gears. H. WITHERS. 2 Dec., 1966 [3 Sept., 1965], No. 37840/65. Heading F2D. Where the existing gear shift lever 10 (Fig. 1) of a vehicle is pivoted at a distance from the driver, thus requiring large hand movements for gear shifts, a second shift lever 20 is provided, pivoted close to the driver's seat and connected to the existing lever 10 and to the gear selecting mechanism. The lever 10, having a ball pivot 11, is connected to an arm 52 secured to a selector shaft 18 (Fig. 6) by a linkage 12-17. The second lever 20 is pivoted by a transverse bolt 24 to a block 23 secured to one end of a rotatable shaft 25 from the other end of which projects a fork 34 embracing the lever 10. Thus transverse rocking of lever 20 causes transverse rocking of lever 10 for gear selection. Fore-andaft rocking of lever 20 about the bolt 24 for gear engagement/disengagement is transmitted to the arm 52 to rotate selector shaft 18, via a rod 40, connected at one end to an extension 21a of lever 20, cranks (44, 48) (Fig. 5, not shown) on a shaft 45 rotatably mounted on a bracket 26, and a rod 51. In (Fig. 7), a second shift lever 60 is connected only to a stub 83 of an existing shift lever. A shaft 62 having a U-shaped end-piece 69 is rotatably supported by a rubber bush 64 and a ball pivot 70. .A pair of triangular plates 77 are pivoted at 78 to the end-piece 69, at 80 to a link 79 pivoted to the stub lever 83, and at a third point to a pair of rods 85 secured at their other ends to brackets 86 pivoted at 88 to the lever 60. Any movement of lever 60 produces movement in the corresponding sense of the stub lever 83.

Title: Improvements in or relating to clutches
Inventor: COX HARRY CHARLES
IPC: F01P5/12
Filed: 1965-09-04
Abstract: 1,132,714. Friction clutches. WILMOTBREEDEN Ltd. 30 Aug., 1966 [4 Sept., 1965], No. 37899/65. Heading F2C. A temperature-responsive friction coil spring clutch 23 between an engine cooling fan 17 freely mounted by a shaft 18 arranged coaxially within a shaft 4 of the fan driving pulley 1, is coaxially located between the shafts 18, 4 in the engine liquid, or air, coolant and is engaged when increasing temperature causes relative radial expansion, or contraction, between the shafts and coil spring to grip and provide a drive therebetween. As shown, the coil spring 23 is partly, e.g. first two coils 26, or wholly, bimetallic and secured at one end to a collar 24 fast on the fan shaft 18, a bush 28 being mounted on the shaft 18 within the spring 23 which it supports radially. A water impeller 7 fast on the inner end of the pulley shaft 4 assists in circulating the liquid coolant which passes through the inner end of shaft 4 and bore 30 of shaft 18 via radial holes 32 therein to a chamber 29 in the bush 28, which bush 28 has radial holes 33 to evenly distribute the coolant over the coil spring, the coolant then returning to the impeller chamber via ducts in a nylon bush 20, supporting the inner end of shaft 18, shaft 4, spacers 8 and impeller 7. The shaft 18 is supported at its outer end by a ball race 19 carried within the shaft 4 which is supported in the impeller housing 6 by a double ball race 5 lubricated through a screw-hole 16, water seals 22, 13 serving to protect the ball races from the coolant. Instead of the single spring with the bimetallic portion 26 and normal spring portion 27, two separate springs, one bimetallic, the other normal, may be disposed coaxially one within the other and may both be of helical form or the main clutch spring may be helical and controlled by a flat spiral temperaturesensitive spring positioned within or outside a free turn of the main spring. In this case both springs are of flat strip and as an alternative to the bimetallic construction the flat spiral thermo-sensitive spring may be formed as a Bourdon tube. Again, this spring may be of thermo-sensitive wire with a gripping action resulting from an increase in the wire crosssection as the spring temperature rises and to this end, the wire may be a tube through which the coolant is passed. Alternatively, either the input or output clutch members may be made temperature sensitive so that on an increase in temperature of that member it expands into gripping engagement with the coil clutch spring. The fan 17 is of synthetic plastics material injection moulded directly on the shaft 18 and formed with bores 35 providing access to screws 2 to release the pulley flange 34 thus enabling the fan 17, shaft 18, clutch spring &c., water seal 22 and bearing 19 to be removed as a unit for service or replacement.

Abstract: 1,073,830. Films; extrusion sheeting machines. E. I. DU PONT DE NEMOURS & CO. Sept. 6, 1965 [Oct. 19, 1964], No. 38019/65. Headings B5A and B5B. [Also in Division D1L] In apparatus for forming a layer of viscous material, consisting of a smooth, continuous casting surface carried by a wheel journalled in a stationary frame, and an extrusion hopper supported by the frame adjacent the casting surface, there is provided a sensing device, upstream of the hopper, so that variations in the casting surface are detected and signalled to means for adjusting the position of the hopper relative to the casting surface, thus ensuring uniform film thickness. In Fig. 1, frame 1 carries casting. wheel 2, feed hopper 9 and floating sensing device 13, which is constrained by the frame except for movement in a direction normal to the casting surface. The sensing device is supported in this direction by a stream of gas which flows into the housing of the sensing device via tube 23 and flows out between the bottom of the housing and the casting surface. Eccentricities in the rotation (e.g. wobble) of the casting surface causes the sensing device 13 to tilt or to move towards or away from the casting surface. Any such change from the preset position of the sensing device is detected by differential transformer detectors 14A, 14B, which generate signals which are trasnmitted to electronic analogue-to-digital converters 16A, 16B. These signals are then delayed (to compensate for the distance between the sensing device and the hopper 9) by temporary storage on magnetic memory drum 17. Signals from feedback detectors 15A, 15B, which monitor the position of hopper 9 with respect to wheel 2, are transmitted, together with the delayed signals from drum 17 (reconverted to analogue form at 18A, 18B) to differential amplifiers 19A, 19B. The signals are here differentiated to give resultant error correction signals for transmission to variable-power amplifiers 20A, 20B connected to independently operating magnetostrictive actuators 7A, 7B. The error correction signals cause the actuators to lengthen or shorten, thus moving hopper 9 upwards or downwards, to adjust the thickness of the layer or film. The casting surface may be integral with the wheel, which may be provided with spaced bead-forming grooves, or may be an endless metal belt supported by the wheel. The apparatus may be used for casting films from molten polymers, or for the formation of uniform coatings on webs of film, foil or textile material.

Title: Improvements relating to the production of aluminium
IPC: C25C3/20
Filed: 1962-10-11
Abstract: Aluminium is produced in an electrolytic furnace from a fluoride electrolyte comprising cryolite (3NaF.AlF3), AlF3 and dissolved Al2O3 maintained at a temperature between 940 and 960  DEG C., the concentration of Al2O3 in the electrolyt being maintained between 5 and 7% by weight, and the concentration of AlF3 in the electrolyte being maintained between 5 and 7% by weight above that amount which is stoichiometrically demanded for combination with NaF as cryolite. Prebaked or self-baking carbon anodes are used and current efficiency is calculated from the concentration of CO2 and CO in the anode gases. A current efficiency of 90-96% can be achieved.  The electrolyte crust may be automatically broken at intervals of 1/4 -3 hours, e.g. every 1-2 hours, and alumina and aluminium fluoride supplied.  At least once every 48 hours and at most twice every 24 hours an anode effect may be made to occur by allowing the concentration of alumina in the electrolyte to drop to 3-2.5% while maintaining the temperature.  During the anode effect, gaseous impurities, slag and oxides are driven out of the electrolyte and a uniform Al2O3 concentration is obtained.
