Title: Improvements in methods for measuring visibility
IPC: B64F1/20
Filed: 1965-07-13
Abstract: 1,066,565. Photo-electric visibility measurement. F. FRUNGEL. July 13, 1965 [July 18, 1964], No. 29678/65. Heading G1A. Visibility is determined by apparatus including a detector which views a row of flashing lamps, the lamps being spaced at distances from each other corresponding to increments of distance in which the range of visibility is to be measured and the detector being positioned so that it receives light from the lamps in directions slightly oblique to the row of lamps. The detector produces a signal dependent on its total number of flashes received in a certain time, the light being received from the furthest visible and all nearer lamps. The row of lamps (1a-10a, Fig. 1 (not shown)) may be located along an airfield runway, being supplied in association with the runway lamps (1-10). The detector is located on the ground near the runway, or may be mounted in a aeroplane, approaching the runway, which receives a signal to indicate its distance from the flash lamps or whose detector has a known angular field of view. The flash lamps are arranged at known spacings, often equal spacings and caused to flash at known frequencies, which may either be the same for all the lamps, or different, the frequency for any one lamp being proportional to the distance from the detector location. The frequencies may vary as the intensity of the associated runway lamps varies, but compensation is made for this in the visibility indicated. The detector output is applied to an amplifier (35a, Fig. 2 (not shown)) followed by a multi-vibrator and an indicator (36) calibrated in visibility ranges. The sensitivity of the amplifier (35a) may be regulated by an amplifier (35b) to allow for differing effective visibilities in daytime. The lamps are flash-tubes Fig. 3 (not shown) filled with rare gas and are provided with parabolic (47) and cone-shaped (48) reflectors in order to radiate the light, which is infrared or ultraviolet near to the visible spectrum, radially in a flat plane.

Title: Improvements in or relating to proofed fabrics
Inventor: HARRISON STANLEY RICHARD
IPC: D06M15/227
Filed: 1962-08-03
Abstract: A fabric, e.g. cotton fabric, is coated with a composition of a vulcanized interpolymer of ethylene and propylene with or without one or more copolymerizable compounds serving to confer unsaturation on the unvulcanized interpolymer, wherein the interpolymer contains from 40 to 75 mole per cent of ethylene. The interpolymer may contain from 0,5 to 5 mole per cent, e.g. 1,0 to 3 mole per cent, of a compound serving to confer unsaturation.  The compound serving to confer unsaturation may be an open-chain or ring diolefinic compound, an acetylene, or a bridged-ring hydrocarbon with at least two double bonds, such as an endocyclic hydrocarbon containing 7-10 carbon atoms and a bridge of one or two methylene groups, examples of which are given.  The molecular weight of the interpolymer may be in the range 100,000-500,000, the Mooney viscosity ML-4 at 100  DEG C. being in the range 20 to 80.  The interpolymer may be extended with 0-100 parts by weight of paraffinic and/or naphthenic oils per 100 parts by weight of polymer.  The composition may contain 50-300 parts by weight of fillers, examples of which are given, per 100 parts by weight of polymer.  The coated fabric is prepared by applying a composition of the interpolymer, and then vulcanizing the composition.  The composition may be applied by spreading as a dough formed with a suitable solvent, or blended with interpolymers of low molecular weight, in which case no solvent is necessary.  More than one coating of the composition may be applied.  Suitable vulcanizing agents are specified. Specification 880,904 is referred to.

Title: Fluid pressure control valve
IPC: F16K31/126
Filed: 1960-08-30
Abstract: 917,180. Fluid-pressure brakes. BENDIX CORPORATION. Aug. 30, 1960 [Oct. 30, 1959]. No. 29932/60. Class 103 (1). [Also in Group XXIX] A control valve for a fluid-pressure braking system has a closure member 50 urged by a coil spring 52 to sealing engagement with a valve seat 42 and which may be disengaged therefrom with a tilt action by a member 46 having a line of force falling within the area bounded by the seat and off-centre with respect to that of the spring. When the brakes are to be applied, the pressure in a passage 26 having a connection 20 with the master brake cylinder is increased to displace a piston 28 and the tubular member 46 to the right until engagement with the closure member 50 isolates chamber 34 and the space 18 with which it is connected from chamber 32 communicating with a vacuum connection 14 through a passage 16 and a space 12. Further movement to the right lifts the member 50 to permit air to flow into the space 18 and drive the piston B to the right so that fluid is expelled by a piston 10 from an hydraulic cylinder D into the braking system, the piston 10 closing a fluid supply valve 24 during its movement. When the pressure ceases to increase in the passage 26 increased air pressure on a diaphragm 44 causes the member 46 to move to the left until the member 50 re-seats while a decrease of pressure in the passage 16 causes the member 46 to move further to the left into the position shown until the differential pressure on the diaphragm 44 has decreased sufficiently for the lower hydraulic pressure to re-engage the member 46 with the member 50. The member 46 applies a lifting force to the member 50 eccentric to that applied by the loading spring 52 so that the member, which is of resilient material, such as neoprene, is deformed and tilted as it lifts. A snap-ring 58 in the periphery of the member slides on axial guide surfaces 60 formed in the walls of the chamber 36. The loading spring may have coils of the same diameter with the distance separating each of the coils along one side of the spring being less than that on the opposite side so that a higher force is applied at one side of the member 50 than at the other or the coils may be of progressively increasing diameter to make the centres of the end coils offset with respect to each other. If a spring with a partial end coil is used a stiffening ring is provided in the member 50 or is positioned between it and the spring. Specification 692,007 is referred to.
