Title: Improvements in Radiotelegraphy Apparatus.
Inventor: MELLERSH-JACKSON WILLIAM JOHN
IPC: H01F21/00
Filed: 1916-01-07
Abstract: 100,384. Jackson, W. J. Mellersh- (Arbib, A.). Jan. 7, 1916. Transformers.-An adjustable transformer for wireless telegraphy comprises a primary coil with two or more mutually-inductive and relativelymovable subdivisions, a similar secondary coil, and means for adjusting the coupling of the primary and secondary coils. As shown in Fig. 1, one subdivision of the primary coil is wound on a cylinder 6 secured to a standard 2, and the other subdivision is wound on a cylinder 5, which may be telescoped over the cylinder 6. The secondary coils are similarly wound on cylinders 7, 8, which may be telescoped one within the other, and both may be telescoped into the coil 6. The subdivisions of both primary and secondary coils may be connected in series or in parallel, and may be wound so as to assist or to oppose each other. In a modification, shown in plan in Fig. 9, the coils are wound on spherical segments. The movable support 17 carrying one division of the primary coil is pivoted on a vertical pin 18 so as to swing relatively to the fixed segment 16. The segment 20 carrying one of the secondary coil divisions is pivoted on vertical trunnions 21 projecting inwards from the segment 17, and the inner segment 22 carrying the other secondary coil division is pivoted within the segment 20 by means of radial horizontal pins 23. The self-induction of the primary is adjusted by swinging the segment 17 by the handle 19, and that of me secondary by turning the pins 23 and inner segment 22 through any angle less than 360 degrees. A pointer 28 indicates the latter adjustment on a disk or knob 24. The secondary may then be adjusted relatively to the primary by rocking the outer and inner segments 20, 22 as one unit about the vertical trunnions 21. The primary windings 16<a>, 17<a>, Fig. 11, are in series and are connected to the binding-posts 34, 36 through a switch 35, which may be thrown over so as to cause the two windings to assist or to oppose each other. The secondary windings are connected to posts 30, 33 through the trunnion pins 21, 23.

Patent GB-1338423-A (GB)
Title: Automatic voltage control system
IPC: H01J37/24
Filed: 1971-01-05
Abstract: 1338423 Automatic control of electron microscopes HITACHI Ltd 5 Jan 1971 [16 Jan 1970] 472/71 Heading G3R To prevent discharge in the accelerating tube 9 of an electron microscope 100, the discharge current is sensed and compared with a reference signal to derive an error signal which is used to vary the output voltage of the DC supply 1 to the accelerating electrodes 6, the arrangement being such that the voltage is decreased or increased when the discharge current exceeds or falls below the reference value. A signal representative of the discharge current is obtained from a condenser plate 7 through which the electron beam passes and is passed, via an amplifier 11, to a comparator 12 which produces a high or a low level signal S1, S2 corresponding to upper and lower values of discharge current which define an operating range about the reference value. The signals S1, S2 are supplied to a control circuit 13 which varies the AC supply to the transformer T1 of the supply 1. The comparator 12, Fig.2 (not shown) comprises a differential amplifier to whose inputs are fed a reference voltage and the voltage El representative of the discharge current and whose output supplies two parallel-connected one-shot multivibrators (one in series with a sign changer) which feed the respective inputs of a flip-flop circuit whose outputs produce the signals S1, S2. The control circuit 13, Fig.3 (not shown) comprises a relay having two switches respectively connected to opposite polarity supplies, so that one or other switch is closed by the corresponding signal S1 or S2 to energize a servomotor controlling the position of a tap on the secondary winding of a transformer forming the variable supply 2 to the transformer T1. Thus the tap setting is progressively decreased or increased by the signal S1 or S2 to maintain the discharge current within the operating range, Fig. shown). The described method of control of the accelerating voltage may be used to gradually increase this voltage to a desired value without producing a discharge current harmful to the tube 9, thus providing automatic instead of manual control for the tube aging operation. The discharge current may be detected by an X-ray monitor instead of the plate 7. Filament transformer T3 supplies a Wehnelt electrode through a potentiometer R2 variable to adjust the beam current.

Patent GB-850405-A (GB)
Title: Improvements in the production of alkylpyridines and alkylquinolines
Inventor: COLLINS GEOFFREY ARNOLD
IPC: C07D213/127
Filed: 1958-01-08
Abstract: Alkylpyridines having a methyl or ethyl group in the 2-, 4- or 6-position and alkyl quinolines having a methyl or ethyl group in the 2-or-4-position in the heterocyclic ring are methylated on the a - carbon atom of the alkyl group by reaction with methanol or methyl chloride in the vapour phase at 350 DEG -500 DEG  C. in the presence of an acidic cracking catalyst containing alumina.  From any given starting compound a mixture of alkylated products is usually found. For example, in the methylation of methyl pyridine the corresponding ethyl pyridine is formed and this may then be further methylated to the corresponding iso-propyl pyridine and possibly tert-butyl pyridine.  The preferred catalyst is alumina but silica-alumina or activated earths such as fullers' earth may be used.  The starting materials may have alkyl substituents present in positions other than those specified above. but these groups are unaffected by the reaction.  The ethyl and isopropyl pyridines and quinolines produced by the process may be converted to the corresponding vinyl derivatives by dehydrogenation in known manner, for example by passage over a catalyst containing chromium oxide at 425 DEG -650 DEG C.

In a system for generating polyphase pulses from a single phase source, e.g. for use in a dynamic balancing apparatus, a signal is provided by a frequency-determining stage 3 proportional to the frequency of the pulses from source 1 and is used to set the frequency of an oscillator 5 approximately to the required multiple of that of source 1, pulses from 1 or 3 being used to synchronize oscillator 5 to the exact multiple of frequency of source 1. Pulses from the oscillator 5 are fed to a ring counter 8 which provides 4-phase pulses on lines 10a ... 11b the frequency of which is reduced by bistable stages 12, 13. As described, pulses 1 may be derived by means of a photo-electric cell scanning a mark on a rotating body. The frequency-determining stage 3 may consist of a mono-stable circuit feeding a mean level rectifier. Fig. 3 shows the oscillator 5 in which capacitor 22 is charged via a constant current transistor 21 at a rate determined by the output from the measuring circuit 3, until the Shockley diode 28 breaks down, discharging capacitor 22 and terminating the cycle. The frequency is adjusted by resistor 33 so as to be approximately equal to the desired multiplication ratio and is synchronized by pulses from blocks 1 or 3 fed in via terminals 30 or 31. In Fig. 2 (not shown) capacitor 34 is replaced by diode 32. Components 8, 12 and 13 may be provided in duplicate or triplicate depending on whether a two-or three-phase application is required.
