Title: Improvements in or relating to stone drying apparatus applicable for use in tar macdam and like mixing machines
IPC: F26B11/04
Filed: 1923-11-14
Abstract: 229,370. Parker, F. M. Nov. 14,1923. Rotary apparatus.-Stone drying apparatus which may be mounted upon wheels and combined with mixing apparatus to form a plant for the preparation of tar macadam comprises rotary cylinders 1, 2 mounted upon a frame 4a which can be adjustably inclined to the horizontal, a furnace 6, a suction fan 8, and the usual feed and discharge shoots 3, 11. The inner cylinder is secured to a shaft 13 and the outer one is supported upon rollers secured to shafts 16, the shafts 13, 16 being rotated through gearing from the driving-shaft 17. In operation, the stone is fed by a conveyer 45 into the shoot 3 and passes into the inner cylinder through which it is propelled by the helical conveyer 5 so as to fall into the outer cylinder and thence to the discharge shoot 11, the furnace gases being drawn through the cylinders in countercurrent to the stone by the fan. Fig. 4 shows a modification, in which the material passes from the shoot 3 into the upper cylinder 1 and through the shoot 31 into the lower cylinder and thence to the discharge shoot 11. The inner cylinders are mounted upon shafts mounted in bearings carried by a subsidiary frame 30. Reference has been directed by the Comptroller to Specifications 14705/04 and 220/09.

Title: Method and Means for Radio-Location of a Radio-Receiving Station
IPC: G01S1/30

Abstract: 1,164,518. Radio navigation. SOC. D'ETUDE ET D'APPLICATION DES TECHNIQUES NOUVELLES NEO-TEC. 21 June, 1967 [29 July, 1966], No. 28757/67. Addition to 1,161,798. Heading H4D. In a phase-comparison path-difference radio navigation system of the kind in which spaced transmitters A, B respectively radiate pairs of unmodulated waves of frequencies F 1 , F 3  and F 2 , F 4  and the receiver utilizes the phase of the beat frequency f (much less than any F 1 , F 2 , F 3 , F 4 ) between the frequencies F 1 , F 2  or F 3 , F 4  (f = F 1  - F 2  = F 3  - F 4 ) to afford its hyperbolic position-line, the receiver includes a local oscillator 3 of frequency f, the local oscillator signal is phase-shafted 5 under the control of a motor 6 before being applied to a phase discriminator 7 controlling the motor, and the other input to discriminator 7 is fed selectively from the F 1  - F 2  beat frequency channel 1 or from the F 3  - F 4  beat frequency channel 2. The shaft of motor 6 is also coupled, via a speed reducer 9, to a phase shifter 10 and the output of further phase discriminator 11 automatically keeps oscillator 3 on frequency f. The speed reduction ratio N equals F 1 /(F 1  - F 3 ). Switch 31 permits operation at least for a short time if the signal on channel 1 is lost. To prevent possible drift of oscillator 3 switch 32 is opened at the same time as switch 31 is placed in its lower position. If the signal on channel 2 fails, switch 31 is retained in its normal, upper, position and switch 32 is opened. A system is described in which each transmitter radiates four waves, the four beat frequencies ensuing all being of frequency f, and measurements at different sensitivities ensuing, Figs. 2 to 5 (none shown).

[Also in Division C3] Shaped products, particularly fibres, consisting of a mixture of not more than 60% by weight of a polyamide (or of a copolymer of an amide with a minor proportion by weight of another monomer) and of at least 40% by weight of a polymer of an aromatic vinyl compound (or of a copolymer of such a compound with a minor proportion by weight of another monomer) may be made by melt extruding the mixture at a temperature above 230 C. and less than 310 C. The atmosphere in the zone through which the filaments pass on leaving the spinneret and which extends from the spinneret face to a boundary plane 10 cm. distant from the spinneret face may be artifically cooled to such an extent that the mean temperature of the atmosphere in this zone is not less than 10 C., and preferably not less than 20 C., below the mean temperature which would obtain in the zone if such artificial cooling were not effected, and the mean temperature of the atmosphere of the zone is not below the mean ambient in room temperature, which may be about 30. The filaments, after having been solidified be stretched at a stretch ratio over 3 and below 10 at a temperature above 95 and more than 5 C. below the melting point of the polyamide. Alternatively the filaments may be stretched first at 130 to 195 C. and a stretch ratio of 2 to 6 and then at 200 to 230 C. at a stretch ratio of 1.2 to 3 the vinyl polymer constituent may be extracted from the fibres by means of a solvent which dissolves the vinyl polymer but not the polyamide, a cellular micro-structure thus being imported to the fibres. The aromatic vinyl compound which in polymeric form constitutes the second constituent of the fibres may be styrene, a vinyl-toluene, a chlorostyrene, a dichlorostyrene, acenaphthalene or alphamethyl styrene. These may be copolymerized with compounds such as vinyl chloride, acrylonitrile or propylene.

Title: Method of operating a pressure water-cooled atomic reactor

Abstract: 966,182. Generating steam by reduction of pressure. ATOMENERGI A.B. July 26, 1963 [Aug. 2, 1962], No. 29749/63. Heading F4A. [Also in Division G6] A method of operating a nuclear reactor comprises withdrawing water at high pressure and temperature from the reactor, decreasing the water pressure, utilizing the resulting steam generation for increasing the velocity of the steam-water mixture, separating the steam from the water, converting at least part of the kinetic energy of the separated water into pressure, and utilizing the pressure for returning the water into the reactor. In Fig. 1 water from a reactor 1 passes through a pipe 2 to guide vanes 6 arranged to impart a rotary motion to the water. In the zone of the guide vanes the water velocity is increased partly because of a decreasing flow area and partly due to steam generation. Steam is separated centrifugally at the vortex 7 and led by a pipe 5 to a turbine (not shown). In the lower part of the steam generator 3 the kinetic energy of the water is reconverted into pressure which is sufficient to return the water through pipe 4 to the reactor 1; the circulation is self-sustaining but a pump (not shown) is necessary to start the circulation. In another arrangement, Fig. 3, the water velocity is increased by a restricted passage 13 and the steam-water mixture passes through vanes 14 which impart a rotary motion to separate the steam, which exhausts through pipe 18. In the vaned diffusor 16 the rotary motion is counteracted and the water returns to the reactor 11 through pipe 17.
