Title: Improvements relating to Mass Spectrometry
Inventor: POWERS PATRICK
IPC: H01J49/32
Filed: 1966-05-17
Abstract: 1,161,432. Mass spectrometers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 10 May, 1967 [17 May, 1966; 9 Sept., 1966], Nos. 21827/66 and 40297/66. Heading H1D. In a mass spectrometer a plurality of separate mass spectra differing in respect of resolution and/or in respect of materials whose mass spectra are to be obtained are produced by sweeping, by means of single scanning variation of a beam-deflecting field, one or more ion-beams across a plurality of collectors. Where the spectra are to differ in respect of resolution, the spectrometer may utilize a single ion beam and a plurality of collectors associated with slits of differing resolution capability, or a plurality of ion beams differing in resolution and possibly derived from a single ion source may be used. Where the spectra are to differ in respect of the materials being analysed and, for mass marking, two or more beams may be derived from two or more ion sources, at least one source providing ions of a material to be analysed and another providing ions of a material, e.g. perfluorokerosene, whose mass spectrometric analysis is known. The spectra may then be recorded side by side and the mass numbers of the peaks compared. A single spectrometer may combine arrangements both for obtaining high resolution and low resolution spectra and for mass marking. As shown, two rectangular beams 8, 10 emerging from source slits 2, 4 are collimated by slits at the position 14 and deflected in the magnetic field H to fall on collector slits in the plane 12. The collimating slits may intercept the beams in both the y and z direction and need not be in line or in the same plane. The source and collector slits may be adjustable. The spectrometer may be of the double-focusing type.

Title: Logic circuit arrangements
IPC: H03K19/018
Filed: 1966-09-14
Abstract: 1,115,876. Transistor logic circuits. NATIONAL CASH REGISTER CO. 14 Sept., 1966 [28 Oct., 1965], No. 41067/66. Heading H3T. [Also in Division H1] A logic circuit, including a plurality of inputs 21 applied through respective diodes 20 to the base of a switching transistor 18, is provided with a voltage reference circuit connected at the input thereof to ensure a constant voltage level of the signal applied to the base of transistor 18. The reference circuit includes resistors 30 and 22 and a string of diodes 24, 28 poled to provide a current path between a voltage source 26 and a reference potential (earth). When all the inputs 21 are at a first binary level (+ 4 volts) the diodes 20 are reverse biased and a predetermined constant voltage developed across diodes 24, 28 is applied to the base of transistor 18 to cause it to conduct, and when at least one of the inputs 21 is at the second binary level (+0À4 volts), the associated diode 20 becomes forward biased to apply the second binary level to transistor 18 to render it non-conductive. The reverse biasing of diodes 20 when all inputs are at the first binary level prevents spurious switching by isolating transistor 18 from input noise. Temperature compensation is achieved by resistor 32 having a positive temperature coefficient, and also by diodes 24, 28 having a negative temperature coefficient. The temperature compensation not only prevents output signal variation, but also prevents variations in the delay time of the circuit resulting in variations in the charge stored in the transistors. Transistor 18 is operated, when switched on, in non-saturated conditions, thus reducing the charge stored and the delay time. Figs. 6 and 7 (not shown), illustrate how the circuit may be adapted for monolithic integrated construction.

Abstract: 1,089,925. Capacitors. LONDON ELECTRICAL MANUFACTURING CO. Ltd. Aug. 16, 1966 [Oct. 8, 1965], No. 42767/65. Heading H1M. A sheet of thin dielectric material such as mica has rows of holes punched in it, e.g. as shown six sets of three holes, and areas 18 to 30 are metallized, the metallizing being continued through the holes to cover the walls thereof. A symmetrical pattern is metallized on the opposite side, the strip 30 contacting the strip corresponding to strip 18. The sheet is severed through the holes and between the sets of holes into nine plates which are assembled to form a capacitor, similar metallized areas being in contact and a straight edge always being adjacent an edge containing half holes. To form reliable electrical contact between the plates, the edges which include the metallized half-holes are coated with a metal paste, the capacitor being heated to convert the paste to a homogeneous metal coating to which electrical connections may be made. When only a few plates are used, added thickness may be achieved by means of end packing sheets formed by severing the sheet shown in Fig. 3 which is rather thicker than the first, and is metallized along strips 35 to 38 on both sides and on the walls of the punched holes. The paste and the metallizing may be of silver.
