IPC: B05C19/00
Filed: 1966-02-15
Abstract: 1,138,494. Ornamenting. FARBENFABRIKEN BAYER A.G. 15 Feb., 1966 [15 Feb., 1965], No. 6623/66. Heading B6G. [Also in Division B2] In depositing flocks on mouldings against the influence of gravity by means of an electric field, the flocks are guided on an earthed, conductive, flock-carrying belt 10 into at least one zone beneath a moulding 1, means being provided in said zone for supplying a high voltage to a conductive holder 2 for the moulding 1 which holder is arranged at a distance above the belt, is insulated from earth and is moved through said zone. The holder 2 is connected to a pinion 5 by way of a shaft 3 and an insulator 4 and the pinion 5 engages with a rack 6. A number of such holders can be attached to a conveyer chain 7 driven by a motor via chain wheels 8 such that the holders can be transported through a series of zones and at the same time be rotated about their axes. Each shaft 3 carries a contact wheel 12 which engages with rails 13, carrying a high voltage, at each zone. Thus at each zone the holders are at a high voltage and the flocks are attracted from the belt on to the moulding, which has been previously coated with adhesive. The voltage applied to each rail 13 can be varied and different and the spacing of the holders from the belt can be varied. The holders and the belt can be arranged to move in the same direction or in opposite directions or at an angle, one to the other.

Abstract: 608,986. Piezo-electric crystal mountings. GENERAL ELECTRIC CO., Ltd., WELLS, G. M., and SUTTON, J. M. March 4, 1946, No. 6634. [Class 40 (v)] A method of mounting a quartz crystal plate that is required to vibrate in a thickness shear mode, comprises first coating small areas 2 of both major surfaces of the crystal with a metallic deposit to which metal parts can be attached, thereafter soldering thin strips 3 of metal to the surface of the crystal, then bending the free ends of the strips 3 around mounting wires 4 and soldering the free ends of strips 3 to the coated areas on the other major surface of the crystal. The strips 3 are also soldered to the wires 4. Electrode coatngs 5, 6 of gold, silver, aluminium or platinum, are applied by sputtering or evaporation, the thickness being subsequently increased to give the desired frequency of vibration. The element may be mounted in an evacuated tube with the mounting wires projecting from the ends. Or, the mounting wires may be fixed to the crystal corners at their ends, the intermediate portions of the wires being formed into loops for. attachment by screws to a base. In a modification, Fig. 3 (not shown), the mounting wires are attached to the crystal only at the mid-points of two opposite edges.

Abstract: 1286599 Super-conductors THOMSON-CSF 11 Feb 1970 [13 Feb 1969] 6668/70 Headings H1A A5 and A4D A hollow stabilized super-conductor cable is produced by introducing a core of removable material into a tube of stablizing material, drawing down, lining the external surface with superconductor elements, inserting into a second tube of stablizing material, drawing down to embed the super-conductor elements and to reduce the crosssection, and removing the core. As shown, Fig. 3, a core comprising a sealed aluminium tube 4 with a filling 3 is drawn down inserted into a tube 5 of stabilizing material, and the assembly is further drawn down and shaped. Super-conductor wires 6, which may be single or composite structures are arranged round the surface and enclosed in an outer sheath 7 of stabilizing material. The assembly is then drawn down to cold weld the tubes of stabilizing material together to embed the super-conductor wires and to reduce the cross-section to the required dimensions and shape. The ends of the cable are cut off and the core material removed, for example by heating to melt the filling 3, followed by etching to remove the tube 4, so that a hollow structure is formed. The inner tube of stabilizing material may be formed with individual surface grooves to receive the super-conductor wires, Fig. 6 (not shown), or may have wide grooves into which a plurality of super-conductor wires separated by copper strips are inserted, Fig. 7 (not shown). The core filling 3 may comprise a solid, a powder, a liquid, or a gas which liquifies under pressure. Alternatively a single solid core member may be used. Removal of the core or its component parts may be effected by any suitable physical chemical or biological method.

Title: Improvements in or relating to modulated oscillators
Inventor: PARKYN JOHN MICHAEL
IPC: H03C1/04
Filed: 1960-02-26
Abstract: 889,470. Modulating circuits; valve oscillator circuits. MARCONI INSTRUMENTS Ltd. Sept. 27, 1960 [Feb. 26, 1960], No. 6807/60. Classes 40(5) and 40(6). An oscillator having a tuned anode circuit inductively coupled to the grid circuit 3, has the contribution of inter electrode capacitance to oscillation neutralised by capacitance between the coupled inductances, so that only the inductive coupling is effective. A condenser 8 may be used as neutralizing capacitance but if the inductances are sufficiently tightly coupled their inherent capactance may be sufficient to produce the necessary neutralizing. Amplitude modulation is effected by a modulating signal applied to the screen grid from a source 7. The neutralizing capacitance substantially reduces undesired frequency modulation in the output at 6.

Abstract: 1, 39, 031. Centrifugal separaters. ESSO RESEARCH & ENGINEERING CO. Feb. 21, 1963 [Dec. 4, 1962], No. 7050/63. Heading B2P. A disc -stackcentrifuge comprises a stationary casing 25 and a rotatable bowl 41 which consists of lower and upper members 26, 27 joined together and defining a double frusto-conical space including a separating chamber 11 in which stacked conical discs 7, 8 and 10 are mounted around a centre part 6 and rotate with the bowl. The lower conical disc 10 is supported by struts 50 from the part 6 and extends downwardly and upwardly to define with the inner surface 15 of the bowl member 26 a passage 56 open at its upper end to the separating chamber 11. An axial first inlet 1 leads through the bowl member 26 to the separating chamber 11; a second inlet 28 coaxial with the first communicates with the passage 56; an axial outlet 19 leads from the top of the bowl member 27; and a number of discharge nozzles 9 are arranged radially at the junction between the bowl members 26 and 27 and extend into the separating chamber 11. Accelerator vanes extend between the inner periphery of the bowl and the outer periphery of the disc stack. The operation, when separating solid particles from a light feed liquid, e.g. crystalline wax from oil, the mixture of light liquid and solid particles is fed through the inlet 1 and after impinging on a curved surface 46 at the bottom of the post 6 is thrown outward by the action of centrifugal force and by vanes (not shown) in the space 2 towards the separating chamber 11 where it rises through holes 4 in the stack of discs, separation between the liquid and the solids taking place between the discs. The clear liquid rises through holes 5 in the discs and is discharged via the outlet 19 into a chamber 22 and out through a conduit 23. The solids and part of the light liquid fill part of the space between the outer periphery of the disc stacks and the inner periphery of the bowl. Auxiliary liquid, e.g. calcium chloride brine, heavier than the light liquid and the solids is fed, via an inlet 31, a chamber 29 and openings 30, through the inlet 28 and passage 56 into the chamber 11 where it fills the space 16 between the bowl inner periphery and the nozzle inlet opening 13 and forms a liquid-liquid interface 40 with the light liquid component on which the solid particles float. As the heavy auxiliary liquid discharges through the nozzles, it picks up the floating solid particles and carries them out of the bowl towards a discharge outlet 21. Some of the auxiliary liquid may also be fed with the mixture of light liquid and solids through the inlet 1 in order to facilitate separation in the disc stack. The centrifuge may also be used for the separation of solids from a mixture of two liquids of different densities, the heavier liquid being removed with the solids.

Abstract: 548,095. Modulating systems ; frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. June 6, 1941, No. 7172. Convention date Sept. 19, 1940. [Class 40 (v)] Modulation is effected in a generating or amplifying system employing a velocity-modulated tube and an associated resonant chamber, by coupling a variable impedance to the chamber and applying the modulating voltage to vary this impedance. This gives frequency modulation in the case of a generator, and amplitude modulation in the case of an amplifier. Fig. 1 shows a generator tube of known type comprising resonant chambers 2, 3, associated respectively with the control grids 8, 9 and the pick-up grids 11, 12, and with feed-back provided by the coupling conductor 19. Output is taken by the loop 15 and lead 16, and modulation is effected by a variable capacity 25, 26. The plate 25 is connected to a loop 20 sealed into the chamber 3, and the plate 26 is flexibly and conductively connected to the housing 23 and is vibrated by a moving-coil device 30 connected to the source MV of modulating voltage. The coupling of the loop 20 may be adjusted by varying its size or orientation. For amplitude modulation, the feed-back conductor 19 is omitted, the input oscillations are fed to the chamber 2 by a loop conductor, and the modulating-capacity 25, 26 is associated with a loop by which the output is taken to the load (Fig. 2 not shown). In a further modification, the capacity 25, 26 is replaced by a known thermionic reactance tube, the modulating-voltage being applied to one of its grids (Fig. 3 not shown). The impedance varied by the modulating voltage may itself be coupled to the resonant chamber.
