Title: Improvements in or relating to a rotor of a rotary wing aircraft
Inventor: BROOKE ROYSE LYNN
IPC: B64C27/50
Filed: 1966-01-17
Abstract: 1,130,311. Rotary wing aircraft. BELL AEROSPACE CORP. 17 Jan., 1966, No. 2026/66. Heading B7W. A helicopter rotor blade 20 is mounted on a pivot pin 76 parallel to the rotor axis, and is prevented from pivoting about the pin by abutments 62 which engage inward extensions 51, 52 of the blade and are adjustable to adjust the position of the blade about the pivot pin 76. The abutments are each mounted on a shaft 44 between a spring (120) (Fig. 4, not shown), and nut (72) or (74) on a threaded end of the shaft, and the adjustment is made by rotating the nuts to move the abutments along the shaft. The abutments are elongate, as shown, so that they, or one of them, may be pivoted about the shaft 44 to lie between the extensions 51, 52 of the blade to allow the latter to fold about the pin 76. A strap 46 connects the shaft 44, which is mounted in a sleeve 30 carrying the pivot-pin 76, and a shaft 48 mounted on the rotor hub 24. The sleeve 30 is rotatable on bearings 32, 34 for blade pitch changes, and the hub 24 is pivotable about trunnions (92), (94), (Fig. 5, not shown) on a see-saw axis above the blade axis.

Abstract: 1,104,228. Liquid break switches. J. L. GRATZMULLER. 20 Jan., 1966 [21 Jan. 1965; 5 Jan., 1966], No. 2685/66. Heading H1N. In a circuit-breaker the arc is quenched in a chamber 2 containing an insulating fluid which. is kept in its liquid state at normal ambient temperature by pressurization. The fluid may be liquefied SF 6 ; SeF 6 ; C 3 F 8 ; CF 3 SF 5  or one of the perhalogenated hydrocarbons known under the Trade Mark " Freon." In a first embodiment (Fig. 1, not shown), the sealed chamber (2) is mounted upon an oil-filled insulator column (4) through which passes an insulating rod 18, connecting the moving contact (6) with an hydraulic actuator (16), and an insulating tube (24) connecting the interior of chamber (2) to a lower chamber (26) of an accumulator (28); the upper chamber (32) of the accumulator, above a free piston (30), is filled with compressed nitrogen gas serving to absorb fluctuations in pressure in the liquid due to changing temperature. An escape valve (38) permits air to be bled from the system. In a modification (Fig. 2, not shown), the interior of column (4) also is filled with the insulating fluid and is in direct communication with chamber (2). The escape valve is replaced by a return connection (44) to the accumulator (28<SP>1</SP>). In a further modification (Fig. 4) both the tubes 24, 44 are within the column 4. Non-return valves 46, 50 are located in these tubes permitting only one way circulation of the liquid between chamber 2 and the accumulator. Such circulation is caused by the fluctuations in pressure caused by changing temperature and may be enhanced by a pump 64. A filter 60 may be included to remove impurities from the circulating liquid. In a further modification (Fig. 9, not shown), the separate accumulator is replaced by an additional chamber (108), above chamber (2) which contains the compressed nitrogen. The accumulator (Fig. 8, not shown), or chamber (108) may be fitted with a sight glass (98) for observing the level of the insulating liquid. Means are also described for filling the circuitbreaker with the insulating liquid either by distillation (Figs. 5, 6, not shown), or directly (Fig. 7, not shown).

Abstract: 794,015. Electron lenses ; X-ray tubes. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Feb. 2, 1956 [Jan. 28, 1955], No. 2699/55. Class 39(1). An electrostatic lens sytem for providing a fine focal spot of high intensity e.g. for producing X-rays, consists of an electrode unit A, Fig. 1, for converting the circular cross-section of a beam originating at 1 into an elliptical crosssection, an electrode unit B for partially converging the elliptical beam, and an electrode unit C for further converging the beam while restoring the circular cross-section. Spherical aberration is corrected partially by each of the three electrode units ; by suitable adjustments of the voltages third order spherical aberration is substantially corrected. The angular aperture of the system is about 0.05 each. The electrode units are symmetrical about the axis. 'Units A and C may consist of 8-poles of alternate polarities, Fig. 2, and unit B of 8 poles of alternate polarities, but with alternate electrodes at different distances from the axis forming two groups B5, B6, Fig. 3. Alternate electrodes in any of the three units may have different shapes e.g. spheres may alternate with laminae. The electrodes may be of any shape such as spheres, laminae or rods. Units A and C may have the same physical arrangement as unit B. In application to the study of X-rays, units B and C are preferably close together so as to provide a large distance between unit C and the target, at the focal point of the lens, so as to permit free movement of an X-ray detector interposed between unit C and the target. Specification 794,014 is referred to.

Title: Improvements in or relating to electrical wave generators suitable for use in television and like apparatus
IPC: H04N5/06
Filed: 1937-02-01
Abstract: 489,666. Television ; converting. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 1, 1937, No. 2951. Convention date, Jan. 31, 1936. [Class 40 (iii)] [Also in Group XXXV] A complex wave form is produced by generating an electrical wave, deriving therefrom a shaped impulse, delaying the impulse to produce another impulse, and combining the two impulses to produce the complex wave. The invention is applied to developing a television synchronizing signal comprising line synchronizing impulses and frame synchronizing impulses, the latter consisting of impulses at twice the line frequency separated by longer pulses, as shown at 52. A master oscillator 1 produces oscillations which are subjected to frequency subdivision at 2 to produce the frame frequency. These oscillations at frame frequency are shaped at 4 to produce impulses 6 at frame frequency, and these are applied to a delay network 9, 11 from which tappings 13, 14, 16 are taken so that pulses 22, 23, 24 are produced, each phase shifted with respect to the others. The pulses 22, 23, 24 are combined to produce the complex wave 27 which recurs at frame frequency. The oscillator 1 is also applied to shaping devices 28, 43 to produce line frequency impulses 31, 45. The impulses 31 are applied to a network 32 from which tappings 30, 34 are taken to produce impulses shifted with respect to each other by such an amount that when they are combined, a sequence 38 is produced of impulses at double the line frequency. This sequence is applied to an amplifier 37 biassed by a pulse 39, derived from the frame frequency source 2, so that it only passes the pulses at frame frequency, thus producing a group 42 of impulses at frame frequency. The pulses 27, 42 are mixed to produce the frame synchronizing signal. The line synchronizing signals 45 are gapped at frame frequency by an amplifier 44 biassed similarly to amplifier 37, and are then mixed with the frame synchronizing signal to produce the final train 52.
