Abstract: 1,024,893. Mass spectrometers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 15, 1963 [Nov. 23, 1962; May 30, 1963], Nos. 44452/62 and 21725/63. Heading H1D. In a mass spectrometer comprising a magnetic analyser and a photographic plate having one surface coated with a layer of ion-sensitive emulsion, the plate is freely supported by a movable carrier, whereby it can be moved into contact with part of a locating structure which then locates the plate substantially independently of the carrier. The mass spectrometer may be of the kind described in Specification 881,388 in which several plates, individually mounted in cassettes, are carried by a rotatable drum from which each can be carried in turn to the analyser chamber. As shown, the locating structure includes two rods 24, Fig. 3, fixed to the spectrometer housing either directly or by bracket 21 and rods 22, and a framework including U-shaped channels 29, 31, which can be moved along rods 24 by a rod 8. Each channel 29, 31 is provided with two spaced locating parts 35 (see enlarged crosssection of channel 31, Fig. 5), each secured to a leaf spring 36 so that its height may be adjusted by a screw 41. The sensitive plate issupported by a carrier 33, 45 having U-shaped side flanges 47, and rests on the lower part of each flange while the carrier is being moved along channels 29, 31 into its required position in which the locating parts 35 engage in recesses in flanges 47 and lift the plate 34 off flanges 47 whereby the plate is located independently of the carrier. One or more electrodes formed with a central slit may be spaced in front of the sensitive plate to suppress stray particles as described in Specification 951,687 and the plate may be backed by an earthed metal sheet or coating, or a metal layer may be provided between the glass plate and the sensitive emulsion, to reduce the potential attained by points on which charged particles impinge.

Abstract: 1,207,019. Wave filters. WESTERN ELECTRIC CO. Inc. 26 Sept., 1968 [29 Sept., 1967], No. 45680/68. Heading H1W. An electromagnetic wave filter includes one or more arrangements of a 3db quadrature hybrid junction having an open-circuited pair of conjugate branches connected in series with a 3db quadrature hybrid junction having a short-circuited pair of conjugate branches (Fig. 6, not shown); the filter behaviour results from the fact that a junction with an open-circuited pair of conjugate branches is equivalent to a series resonant circuit resonant at the 3db coupling frequency, whereas a junction with a shortcircuited pair of conjugate branches is equivalent to a parallel resonant circuit together with a 180 degrees phase shifter. Transposition of the open-circuited and shortcircuited junctions provides a dual filter (Fig. 7, not shown); a balanced output from a broadband unbalanced signal source 79, Fig. 8, may be obtained by the use of a pair of dual filters 80 and 81, each made up of an odd number of similar hybrid junctions, whereby the transfer characteristics of the two filters are the same but their output signals are 180 degrees out of phase, due to the presence of one more short-circuited junction in filter 80 than in filter 81. The 3db hybrid junctions may be Riblet, multihole, semi-optical, or strip transmission line directional couplers or lumped element devices.

Abstract: 1,023,554. Gyroscopic-apparatus; measuring angular velocity and acceleration electrically; photo-electric waveform generators. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Dec. 4, 1962 [Dec. 12, 1961; Nov. 16, 1962], No. 45796/62. Headings G1A, G1C and G1N. Gyroscopic apparatus, in one form Figs. 1, 2, 3 (not shown), but see Fig. 7, comprises a casing C spinning about an axis A-A<SP>1</SP> at an angle to an angular velocity vector to be measured, at least one mass M 1  spinning with the casing C, having its centre of gravity displaced from the axis A-A<SP>1</SP> and mounted for limited displacement relative to the casing in response to the resultant effect of the spin and angular velocities and means for measuring the amplitude of the oscillatory movement thus produced. In another form Fig. 6 (not shown) a measure of acceleration in a direction normal to the axis A-A<SP>1</SP> is given by the amplitude of the oscillatory movement produced in at least one spinning, eccentric mass N 1  mounted for limited resiliently-restrained displacement in response to the acceleration. The two forms may be combined, Fig. 7. Preferably when measuring angular velocity two masses M 1 , M 2  are joined by a rod pivoted at its midpoint about an axis normal to A-A<SP>1</SP>, though the masses may be slidable parallel to A-A<SP>1</SP>. When measuring acceleration two masses N 1 , N 2  with two restraining springs R 1 , R 2  are preferred. Measuring electrically. To measure the amplitude, condenser plates S 1 , S 2 , T 1 , T 2  are mounted in casing C adjacent the lower and upper surface of masses M 1 , M 2  respectively and adjacent the outer faces of masses N 1 , N 2 . The condensers are connected in a tank circuit of a high frequency oscillator associated with the spinning system and the modulated output passes through a discriminator 3 to derive the modulating component for mixing at 5 with a signal derived from photo-cells 7 to produce a D.C. signal proportional to the angular, rate or acceleration to be measured. Two photocells are displaced by 90 degrees, or three by 120 degrees, at stationary points round the periphery of the casing C which is provided with two or more light-reflecting sectors separated by non-reflective sectors. A modified system, Fig. 5 (not shown) functions on a digital basis. Other forms of pickoff can be used e.g. electro-magnetic, resistive or piezo-electric. In the composite apparatus, Fig. 7, three miniaturized oscillator circuits are disposed in the casing C; one associated with the ratemeter masses M 1 , M 2  and one each with the accelerometer masses N 1 , N 2  and a single photo-electric cell system can detect the reference phase angle for all three systems. The apparatus may be applied to inertial guidance and platform stabilization.

The divider is so arranged that the minute hand, and a seconds hand if provided, are stepped once every 2¢ seconds. As shown a minute wheel pinion B drives a cannon C which is coupled to hour wheel C by twelve magnetic spots on each of the wheels C, C'. The coupling is strong enough to drive the hour hand normally, and possibly a calendar mechanism, but can be overcome to permit stepping rotation of wheel C when a key F on a shaft E with pins G is turned manually. A recess in the timepiece case ensures that, when not in use, the key F is locked in a position with the pins G out of engagement with wheel D. In an alternative arrangement, the pins G are replaced by a mutilated gear (G',) Fig. 3 (not shown).
