Abstract: 1286669 Mass spectrometers; ionization manometers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Oct 1969 [26 Oct 1969] 51926/69 HeadingHlD A mass spectrometer device comprisse an ion source 1, an ion separator section 2 with a sector field to produce the ion separation and an ion collector 3 having an ion collector current measuring device 24, and includes an arrangement whereby, by selecting either a constant voltage or pulsed voltage supply to the ion accelerator electrodes 13, 14, 15 and 16 of the ion source, the device functions, as desired, either as a mass spectrometer or as an ionization manometer in which the ion collector current is a measure of the overall pressure of the gas to be analysed. A " constant voltage " is one which is substantially constant at least during a time corresponding to the transmit time of the ions in the ion source, and a " pulsed voltage " is one in which the duration of the voltage pulses is small with respect to the transmit time of the ions in the ion source. When a constant voltage supply is applied to the accelerator electrodes of the ion source 1 ions of the same energy to charge ratio are extracted, and if these are fed, as shown, into a magnetic sector field, which selects ions according to the square root of their mass to charge ratio, only ions of a given charge-to-mass ratio will follow path 23 to be collected on electrode 22, and the device functions as a mass spectrometer. However, with a pulsed voltage supply to the accelerator electrodes ions of constant momentum-to-charge ratio are extracted from the ion source so that all the ions in the magnetic sector field follow the path 23 to the ion collector 22 and the device functions as an ionization manometer. Conversely an electrostatic sector field may be used, Fig. 2 (not shown), and by similar resaoning the device will function as a mass spectrometer if the accelerator electrodes have a pulsed voltage supply and as an ionization manometer with a constant voltage supply.

Abstract: 1,096,557. Clocks and watches. BRAC Ltd. Nov. 28, 1966 [Nov. 29, 1965; Nov. 11, 1966], No. 53109/66. Heading G3T. [Also in Division F2] Angular oscillation of a shaft 33 is converted into unidirectional stepped rotation of a shaft 41, the shaft axes being coplanar and mutually perpendicular, arms 37, 38 extending transversely from the shaft 33 acting alternately on projections 43a-c on the shaft 41 to advance the latter stepwise. In a clock drive, the shaft 33 carries a balance wheel 35 and is acted upon by a spiral spring 39 the outer end of which is anchored at 40. In the rest position of the shaft 33, the bisector of the angle defined by the arms 37, 38 lies in the common plane of the shaft axes. Spring blades 44 act on projections 43d-f aligned with the projections 43a-c to hold the shaft 41 between steps. A single tooth 53 on the shaft 41 drives a sixty tooth gear (52) Fig. 6 (not shown). The oscillation of the shaft 33 is maintained by the action of an electromagnet 47 on a permanent magnet 45 on the balance wheel 35. The electromagnet 47 is energized by a battery 50 via the spring 44, the projections 43a-f, the arms 37, 38, the spring 39, and lines 48, 49 to give two impulses per complete oscillation of the shaft 33. Three oscillations of the shaft 33 give one complete revolution of the shaft 41. In a modification Fig. 8 (not shown) the electromagnet (62) is on the balance wheel and the permanent magnet (63) is fixed, and one arm (67) of the shaft (33) is insulated to give only one impulse per complete oscillation.

Abstract: 1390779 Automatic control of current or voltage SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 27 Nov 1972 [18 Feb 1972] 54793/72 Heading G3R In a chopper circuit, a D.C. input V 1  is chopped by transistor Ts 1  and fed through a smoothing circuit D 1 , L 1 , C 1 , an inverter IN, a transformer T 1  and rectifier RZ to produce an output Vu. The difference between the output voltage or current as sensed by detector S 1 , and a desired value F 1 , is compared in device A 2  with the output of a sawtooth generator GR, which is synchronized e.g. via transformer T 2 , with a chopping signal generator CZ. The output of device A 2 , which depends upon which of its inputs is greater, is differentiated by circuit C 2 R 2  and fed, via transformer T 3 , to electronic switch i 1 , which controls transistor Ts 1  and which is also fed with signals from generator CZ. In use a signal from generator CZ closes switch i 1  to turn transistor Ts 1  on. After a time delay proportional to the difference between the measured output voltage or current and the desired value, which may be adjustable, a pulse from differentiating circuit C 2 R 2  opens switch i, to turn off transistor Ts 1 . The conduction time of transistor Ts 1  is thus controlled to regulate the output voltage or current to the desired value.
