Sept. 26, 1932, No. 26707. Convention date, Aug. 4. [Class 120 (ii).] A bobbin carrier is dragged by providing it with inclined vanes which cause the air to be ejected upwardly therefrom, so thrusting the carrier downwardly on to a friction element with a force dependant on the speed of rotation. The friction element may be loose or attached to the carrier or the bobbin rail, and is preferably conical, whereby the bobbin carrier is self-centring and rotates free from contact with the spindle, which may even be dispensed with. The bobbin is secured to the carrier by providing the latter with studs having enlarged heads, preferably tapered, which enter suitably shaped recesses in the bobbin so that a partial turn of the bobbin secures it firmly to the carrier. The air vanes may be provided with an adjustable shield. The bobbin carrier 8 has inclined vanes 15 which, upon rotation, cause the carrier to press down on to the conical friction element 16. An upstanding wall 19 having adjustable apertures 37 for entry of air may be provided. The device may be secured by bolts 21 to existing bobbin boards, or the latter may have conical recesses formed therein. The bobbin 6a is secured to the carrier by studs 12 which enter recesses 24 in the bobbin, by a partial turn of the latter, the heads of the studs are secured behind constrictions 29. The stud heads are preferably conical to allow for wear,

A semi-conductor device comprises an active layer of a fine powder of semi-conductor material embedded in an insulating organic binder, an inert support for the active layer, contact members connected to the active layer and the support, and particles of an ionizable material, which act as electron catching centres, in the proximity of the support contact. As shown, Fig. 1, a diode comprises a sensitive layer 1 of zinc oxide particles distributed in a copolymer of vinyl acetate and vinyl stearate coated on a paper support 2, a layer 3 containing the particles of ionizable material formed by impregnating paper with a solution of potassium hydroxide and drying, and contact members 4 and 5. Two such devices may be placed backto-back to form a transistor, Fig. 2 (not shown). In either embodiment the layers 3 may be omitted and the ionizable particles provided on the surface of the supports 2. In the case of the transistor the two supports may be provided with different concentrations of different types of ionizable particles, or a single layer 3 may be provided. The semi-conductor material may be N-type zinc oxide, N-type zinc sulphide or N-type germanium, the support may be a cellulosic material in the form of a fibrous web, a woven or unwoven fabric, paper, or inorganic or organic absorbing materials such as sintered materials, ceramics and foamed resins such as polystyrene and polyurethane. The ionizable particles may be obtained by soaking the support or an additional layer in an inorganic base such as an alkali or alkaline-earth metal hydroxide or carbonate, or ammonium hydroxide or carbonate, or in an organic base such as an amine. The active layer may be photo-sensitive. The Specification states that devices comprising a semi-conductor material dispersed in a binder coated on a paper support and having contacts to the support and the semi-conductor layer are known and exhibit rectifying properties.

Title: Improvements in or relating to electrical control circuits
Inventor: MORTIMER JOHN MERVYN
IPC: G05D23/22
Filed: 1961-07-28
Abstract: 958,261. Transistor pulse circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 18, 1962 [July 28, 1961], No. 27383/61. Heading H3T. [Also in Division G3] The timing of triggering pulses to silicon controlled rectifiers supplying an A.C. load is controlled in response to a D.C. signal by comparing the signal with a voltage of sawtooth waveform generated in synchronism with the A.C. supply. The sawtooth waveform is produced across a capacitor C3, which charges linearly each half cycle of A.C. mains applied to transformer T1, from which a D.C. voltage, stabilized by Zener diodes D9 ... D11, is derived. At the end of each half cycle the capacitor is rapidly discharged through transistor J1. The sawtooth is applied to one transistor J2 of a long tailed pair, to the other of which, J3, is applied a portion of the D.C. control signal, amplified by a further transistor J4. At the start of each cycle J3 conducts and J2 does not until the voltage of sawtooth waveform on the base of J2 falls to that on the base of J3. J2 and J3 then switch over and a negative-going edge is generated across R6. This is differentiated by a capacitor C4 to produce a pulse which triggers a single-shot blocking oscillator J5-T3. Thus, the time at which this occurs in each half-cycle depends upon the magnitude of the control signal. The output of T3 triggers two silicon controlled rectifiers SCR2 and SCR3, which are arranged back to back, alternately. SCR1 and SCR4 are connected in series with SCR2 and SCR3 respectively, to achieve the required rating, and it is shown how, when one SCR conducts, its series connected partner is triggered. To prevent overloading the rectifiers, the load current passes through resistor R23, the resultant voltage being stored on capacitor C6. If this exceeds the breakdown voltage of a Zener diode D14 the D.C. signal voltage is opposed at J4, to effect a reduction in the conduction time of the rectifiers.

Abstract: 1338213 Ion sources SCIENTIFIC RESEARCH INSTRUMENTS CORP 13 June 1972 [18 June 1971] 27555/72 Heading H1D In an ion source which is operable in either one of two modes, an electron beam is fired through an aperture into a gas which is either at low pressure, to produce electron impact ionization, or at a higher pressure, to produce chemical ionization, operation in the second mode being effected by changing from the use of a relatively large aperture, e.g. 1À5 mm.<SP>2</SP> or more-to the use of an aperture having sufficiently small dimensions-e.g. 0À15 mm.<SP>2</SP> or less-to provide an impedance to gas flow sufficient to permit the maintenance of the required higher gas pressure in a substantially closed container. In one embodiment (Figs. 2 and 3, not shown) two apertures (20, 22) of appropriately different size are formed in a movable plate (24) which may be adjusted to align either aperture with an electron-emitting filament. Alternatively, the aperture may be in the form of a continuously adjustable slit (Figs. 4 and 5, not shown), in which two plates (42, 44) spring-urged together and having a pair of inclined ends are forced apart to a desired extent by the thrust of a wedge member. In a further embodiment, Fig. 7, a switch 90 permits the energization of either one of a pair of electron-emitting filaments 72 and 82, the electron beams from which pass through corresponding small and large apertures 74, 86 into a high pressure region 70, and a low pressure region communicating therewith through a small aperture 78, the resulting ion beam in either case being accelerated by the plates 80.
