Abstract: 991, 736. Measuring fluid density electrically. SOC. DE PROSPECTION ELECTRIQUE SCHLUMBERGER. Feb. 20, 1963 [March 6, 1962], No. 6870/63. Heading G1N. Apparatus for measuring the density and viscosity of a fluid flowing in a conduit comprises a resilient element in the conduit, torsionally vibrated at its resonant frequency at a constant amplitude,and it is shown that (a) this frequency is indicative of the density of the fluid, and (b) the current required to maintain the amplitude of vibration at a constant value is indicative of the viscosity of the fluid. Construction. (Figs. 1, 9). A cylinder 34 is mounted on a torsion shaft 42 inside the fluidcarrying conduit 10 by radial blades 38 connected to a hub 40, the ends of the shaft 42 being rigidly attached to the conduit 10 by radial blades 22, 31. The lower end of shaft 42 carries a diametrically polarized permanent magnet 64 which is magnetically coupled to an A.C. -energized electromagnet 50, 52, to produce torsional oscillations in shaft 42. The extent and frequency of the oscillations are sensed by coils 74, 76 coupling with permanent magnets 66, 68 attached to the other end of the shaft 42. Circuitry (Fig. 2). The amplitude of the signal Vd developed in coils 74, 76 is compared at 96 with a reference value, and any difference is amplified at 100 and determines the gain of an amplifier 90 controlling the excitation current i in coil 52, whereby the amplitude of the signal Vd is maintained constant. A phase shifting network 104 produces a #/4 phase shift between i and Vd, and it is shown that under these circumstances the frequency of oscillation, measured at 82, is indicative of the density of the fluid in the conduit 10, and the mplitude of the oscillatory current i, measured at 108, is indicative of its viscosity. The values of density, viscosity and temperature, as measured by a thermocouple, are recorded by an automatic printer.

Title: Improvements in or relating to overhead conveyor systems
IPC: B61B10/02
Filed: 1953-03-12
Abstract: 735,907. Overhead conveyer systems. STAHLINDUSTRIE UND MASCHINENBAU AKT.-GES., and NEUTSCH, E. March 12, 1953 [March 12, 1952], No. 6892/53. Class 104 (2). An overhead conveyer system has a plurality of carrier elements connected to rail mounted trolleys driven by a single driving device consisting of drivers connected to an endless chain and capable of engagement and disengagement with the carrier elements or the trolleys and lifting elements which raise the drivers to disengage them from the carrier elements in order that the carrier elements can push one another forward until re-engaged by the drivers. As shown in Figs. 1 and 2 a chain 6 mounted on trolleys provided with wheels 5 running on the upper flanges 4 of U-shaped rails drives a loadcarrying trolley 3, mounted on wheels 2 running on the lower flanges 1 of the U-shaped rails, by means of a pivotally mounted hooked arm 8 engaging a driving member 7 on the trolley 3. Lifting elements 9 fixed to the U-shaped rails at stopping points raise the arms 8 or the wheels 5, and hence an abutment 8<SP>11</SP>, Fig. 5 (not shown), out of driving engagement with the member 7. At the stopping points the trolleys 3 are gradually pushed by succeeding trolleys to the exit end of the element 9 at which point the hooked arm 8 drops into engagement with the member 7. The elements 9 may be adjusted in height by means of screwed members engaging slots in the rails, Fig. 4 (not shown). In modifications, Fig. 3 (not shown), the arm 8 is arranged as a pivoted pusher arm and in Fig. 5 (not shown), as a fixed downwardly extending lug. In the arrangement shown in Fig. 6 the load carriers 12 provided with a driving member 14 and running on rails 13 arranged above the driving chain 19 are driven by a double arm lever 15 pivotally mounted on the driving chain 19 and normally held in the driving position by a spring 16. The lever 15 has a roller 17 mounted thereon which engages guide rails 18 arranged below or laterally to tilt the lever 15 out of driving engagement with the member 14. As shown in Fig. 7, the arm 8 is lifted by a pivoted lever 20 through a cam 21 rotated by a guide wheel 11 driven by the driving chain 6. In a further modification the driving chain trolleys run on the same rail as the load-carrying trolleys which are driven by elements 7 mounted thereon, being engaged by driving abutments 8<SP>11</SP> on the chain trolleys. At stopping points the track is downwardly curved so that the load-carrying trolleys move out of driving engagement with the chain trolleys, Fig. 8, and at the exit end of the stopping point the chain trolley track is downwardly curved; Fig. 9, so that the chain trolleys are moved into driving engagement and on a common track with the load-carrying trolleys. As shown in Fig. 11, load suspension members of the load-carrying trolleys 3 are swung about a vertical pin 23 by a double arm lever 24 engaging an abutment 25.

Abstract: 1,196,126. Caps for containers. W. R. GRACE & CO. Ltd. 7 Feb., 1969 [9 Feb., 1968], No. 6907/69. Divided out of 1,196,543. Heading B8T. [Also in Divisions B4-B5] A method of forming gaskets in metal closures for containers in which a thermoplastic gasketforming material is introduced into the closure, heated and formed into a gasket, is characterized in that the gasket-forming material is heated by subjecting the closure containing it to a high-frequency magnetic field. The material may be a vinyl resin plastisol and the closure containing it may be rapidly spun to distribute it over the inner surface thereof and subjected to the high-frequency field until it is fluxed, and then cooled. Alternatively, the material is heated in the closure by the field until it is sufficiently soft and is then moulded. The gasket material may contain particles of an inductive material which is electrically conductive and/or ferromagnetic e.g. of iron, aluminium, copper or an alloy of iron and nickel. The gasket forming material may include a blowing agent to produce a foamed gasket.

Title: Improvements in or relating to the purification of uranium salts
Inventor: BURRAGE LESLIE JAMES
IPC: C01G43/00
Filed: 1942-05-22
Abstract: Uranium is recovered as the tetroxide from the mother liquors from the crystallization of uranyl nitrate by precipitation with hydrogen peroxide, suitably in 50-100 per cent excess and at temperatures below 25 DEG C.  It is then dissolved, at say 90 DEG C, in a slight deficiency of nitric acid, so as to leave undissolved any vanadium which may be present, and uranyl nitrate crystallized on cooling. This may be reduced to the uranous salt, which is converted to the tetrafluoride by precipitation with hydrofluoric acid.  The solution from which the original uranyl nitrate is crystallized may be produced by dissolving uranium oxide, produced from a carnotite ore, in nitric acid.

Title: Improvements in or connected with aerials
IPC: H03J1/18
Filed: 1920-03-11
Abstract: 164,506. Round, H. J. March 11, 1920. Transmitting systems and apparatus.-In transmitting systems using an aerial coupled with the primary circuit of a valve, alternator, arc or like generator, variation in the wavelength of the aerial due to external causes, such as the swing- ing of the aerial by the wind, is automatically counterbalanced by the actuation of a small rotating-field motor, the stator of which comprises two windings at right-angles, one included in the aerial circuit and the other in a closed circuit coupled with the primary transmitting circuit and tuned to it. In the valve transmitting system shown in Fig. 1, the aerial A is coupled with the primary circuit B of a valve generator. One winding of the stator E is inserted in the aerial circuit, and the other is included in the tuned closed circuit C. If the natural period of the aerial A increases or decreases, a rotating field is set up in one or other direction and the rotor D moves accordingly to actuate the variometer F, which is so connected as to counterbalance and annul the rotating field, the system then coming to rest. In a modification, Fig. 2, a relay H is interposed between the motor E and the variometer F, which is actuated by solenoids G controlled by the relay H operated by a contact arm I mounted on the rotor shaft. The relay H instead of working a variometer may be caused to add or subtract small inductances until the aerial is counterbalanced and the arm I falls back. To avoid changes in the wavelength of the oscillations generated in the primary transmitting circuit when the aerial varies, the grid control of the power valves may be supplied by an independent oscillating circuit to which the closed circuit C is coupled.
