Abstract: 957,084. Mass spectrometers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 9, 1962 [Oct. 19, 1961], No. 37555/61. Heading H1D. [Also in Division G3] A mass spectrometer includes means for providing an auxiliary ion controlling field which tends to prevent drift of the ion beam trajectory relative to the collector assembly. As shown, a mass spectrometer comprises an ion source 1, an electrostatic analyser 10, a magnetic analyser 2 having a field coil 5, a collector 3 and a connecting duct 4. The coil 5 is supplied from a circuit including a voltage source 6 in series with a variable impedance 7 and a sensing resistor 8. A scanning control unit 9 either provides a waveform to vary the current in the coil so that a range of ions is collected or, alternatively, provides one of two or more fixed voltages so that ions of a particular mass are collected. To counteract for the drift of the ion beam trajectory due to variation in the parameters of the analysing system, a drift control unit 11 provides a steadily varying voltage of suitable magnitude and polarity. The difference between the voltage across resistor 8 and the voltage supplied by the units 9, 11 is amplified by a difference amplifier 12 the output from which controls the impedance 7 so as to control the current through the coil 5 and reduce the input of the amplifier 12 to zero. The output from the drift control unit 11 may be selected manually, e.g. in accordance with a meter or oscillator reading taken at the collector 3, or it may be controlled automatically in accordance with the output of a sensing unit, such as a Hall plate or a vibrating coil, located in the magnetic field of the analyser 2. The auxiliary ion controlling field may be an auxiliary magnetic field spaced from the main deflecting field (Fig. 1a, not shown), on auxiliary electrostatic field coincident with or spaced from the main electrostatic field (Figs. 2 and 2a, not shown), or an auxiliary ion accelerating field (Fig. 3, not shown).

In an automatic slack adjuster for railway brake rigging connected to a brake actuating lever 12, a slack adjuster housing 42 is pivoted to the lever 12, a nut member 64 being rotatably mounted in the housing, a screw 20 threaded into the nut and having one end pivoted to the brake rigging, a pawl carrier 110 is slidably mounted in the housing and has a portion extending into the opening of the housing and is in engagement with an inclined plane 138 formed on the lever 12, spring means 112 urging the pawl carrier 110 into engagement with the inclined plane 138 such that movement of the pawl carrier 110 in a direction opposite to the action of the spring 112 releases a pawl 114 from engagement with a ratchet wheel 90 which is press-fitted on to a small flange 92 on the nut member 64. Automatic adjustment takes place whenever the movement of the brake applying lever 12 rotates through a sufficiently large angle and the resultant motions of the parts described will be large enough to engage a further tooth 97 on the ratchet wheel 90 such that, upon release of the brake, the spring 112 urges the pawl carrier 110 to the right and the pawl 114 rotates the ratchet wheel 90 in a counterclockwise direction to effect the adjustment of the slack of the brake. Accidental rotation of the ratchet wheel 90 is prevented by a ball-type latch or detent 94 which is adapted to seat in a recess between the tips of the ratchet wheel adjacent teeth 96. Manual adjustment of the brake rigging is effected by rotation of the end 84 of the nut member 64 by a wrench when the ratchet and pawl is disengaged.

Class 68(1) [Also in Group XXIX] In a shovelling machine in which a scoopcarrying jib 9 and the jacks for actuating the jib and the scoop 11 are mounted on a turret 6 rotatably supported on a vehicle chassis 1, the turret 6 is rotated by a pair of single-acting, hydraulically actuated jacks 23, 24 one only of which is operated at a time, said jacks being interconnected through spring-loaded relief valve means 46. On the interruption of the flow of liquid to and from the cylinders the inertia of the moving turret and the structure supported thereon would, if no valve means 46 were provided between the jacks, result in the creation 'of an excessive pressure differential in the jacks as the rotation of the turret is halted, but because of the valve means 46 the pressure differential is greatly reduced. The valve of the pressure differential is dependant upon the tension of spring-loading means 53 of the two non. return valves 51 of the valve means 46. Each piston rod 29, 30 of the jacks 23, 24 is connected by a chain 39, 34 to the turret 9. Specification 753.008 is referred to.

To obtain uniform field distribution in the gap the poles comprise a frustoconical central high permeability pole 4 (Fig. 2) encircled by a gap filled with non-magnetic material, e.g. resin and a magnetic guard ring of lower permeability; the pole and ring being separated from the armature by a further gap 8. A threaded magnetic ring 6A encircles the outer edge of the guard ring, and the combined effect is to reduce non-uniformity and leakage of flux. The ring 6A is adjustable by rotation to modify the field therein and obtain minor correction of the interpolar flux distribution. In modifications (Fig. 3, not shown) the combined pole profile may be shaped and (Fig. 4, not shown), a rotatable portion of the guard ring may be adjustably threaded to the base circumference of the ring body. In a further modification, the adjustable ring may be threaded to the outer circumference of the end of the magnetic armature (Fig. 5, not shown) and the main body of the guard ring may have a cylindrical surface encircled by an extension of the adjustable ring. The magnetic guard ring may comprise one or more windings carrying electric current and the central pole or the guard ring or both may comprise transverse highly permeable magnetic laminae separated by alternate laminae of non-magnetic material. The latter may be elastic and the assembly may be compressible for adjustment.
