Title: Improvements in or relating to transistor circuits
Inventor: FORREST MICHAEL LAUGHARNE NEVI
IPC: H03K17/0814
Filed: 1959-01-22
Abstract: 868,998. Transistor switching circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 5, 1960 [Jan. 22, 1959], No. 2386/59. Class 40(6) In a transistor switching circuit in which the collector is connected to an inductive load, a capacitor is connected to the collector through an impedance so as to charge when the transistor is conductive and discharge through the load when it is non-conductive, the impedance having a higher value for charging current than discharging currents. Thus, the inductive load 2 (which may be a relay) is shunted by a capacitor 8 in series with a parallel resistor-diode combination 6, 7. When an input-pulse causes the transistor to conduct the capacitor charges slowly through resistor 7. At the end of the pulse the back e.m.f. developed across the load causes the collector potential to rise to a value at which the diode 6 commences to conduct. Accordingly the rise of voltage at the collector is delayed and avalanche breakdown avoided. The input pulse may be applied to the base or emitter and is preferably followed by a reverse pulse to speed the switching off, a further diode 5 prevents excessive voltage being developed across the load.

In a mass spectrometer, a monoenergetic or constant mass ion beam is passed in series through two slits into a perpendicular, homogeneous, high frequency electric field, only those ions arriving at an exit pair of slits with zero transverse velocity being capable of passing through the latter to a collector electrode; the ion mass or velocity satisfying the latter condition depends upon the frequency of the field, which is swept over a suitable bandwidth. The ion beam passes through slits in water-cooled diaphragms 36 and 38 and between capacitor plates 2 and 4<SP>1</SP>, spaced by PTFE members 32<SP>1</SP>, the intermittent exit beam from the slits in diaphragms 40 and 42 passing to a collector 30 connected to a coaxial cable 54 and screened by an electrode 52. The collected ions follow oscillatory paths which lie on one side only of the beam axis; to eliminate unwanted ions which follow paths oscillating alternately to either side of the beam axis, the capacitor plates are asymmetrically disposed with respect to the latter. Numerical data are given, and the use of a sawtooth or square-wave, rather than sinusoidal, voltage is referred to; for these voltages, the exit slits must be displaced from the beam axis.

The end 18 of the platen 17 on the table 11 is curved to hold the end of the film on a shear block and to prevent excess cement from flowing back over the film. The film to be spliced is placed on the tables 11, 12 and the ends cut by the double knife 36 co-operating with shear blocks. A scraper 42 is slidably mounted on the knife 36. A spring pulls the table 12 down in both positions. A pressing member 56 mounted freely by elongated slots on studs 55 fixed in the platen 17 is normally pressed against the heads of studs 55 by the spring fingers 58. When the table 12 slides forward to splicing position the curved end 62 of member 56 slides under stops 60 and transmits pressure to the splice. If pressure over the entire area of the platen 17 is desired a spring arrangement operating in a parallelogram of forces may be employed. The member 56 may also comprise a slotted plate with a spring or springs located between the plate and the platen 17. The Specification as open to inspection under Sect. 91 comprises also splicing apparatus in which the films are held on their respective tables by locating pins spring-pressed apart and in which the platen serves merely as part of the splice-pressing arrangement. This subjectmatter does not appear in the Specification as accepted.
