Patent GB-641955-A (GB)
Title: Improvements in or relating to nitriles and process of making same
Filed: 1947-05-21
Abstract: Aliphatic nitriles of high molecular weight are prepared by heating between one and three mols. of urea and/or cyanuric acid with one mol. of a fatty acid having at least 8 carbon atoms in the molecule at a temperature above 250 DEG  C., but below 310 DEG  C. and in the liquid phase.  Thus, a substantially 100 per cent yield of nitrile is obtained by heating between 1 and 2 mols. of cyanuric acid with one mol. of fatty acid at above 250 DEG  C. for 2-3 hours. If desired, mixtures of urea and cyanuric acid may be used, for example a mixture thereof may contain 40-80 per cent cyanuric acid.  The preferred fatty acids are lauric, oleic, stearic, elaidic and palmitic acids or the mixtures of acids produced by hydrolysis of natural tri-glycerides such as tallow, coconut oil, palm oil, corn oil, peanut oil, rape seed oil and low grade olive oil.  Those acids boiling below 250 DEG  C. may be reacted under pressure in an autoclave.  Less preferred acids are the higher unsaturated fatty acids such as drying oil fatty acids and hydroxylated acids, for example, linoleic, linolenic, ricinoleic and oleostearic acids which may be used, however, if polymerized nitriles are desired.  The reaction mixture may be filtered directly or given a treatment with a decolourizing material such as kieselguhr, adsorbent aluminium silicate or diatomaceous earth. The preferred products contain more than 10 and, desirably, 12 to 36 carbon atoms.  In typical examples: (1) technical stearic acid (10 gms.) and cyanuric acid (5 gms.) are heated under reflux to yield stearonitrile; (2) urea (250 gms.) and coconut fatty acids (500 gms.) are similarly reacted to yield the corresponding nitriles; (3) oleic acid (500 gms.) and urea (250 gms.) are heated at 285-300 DEG  C. to yield oleonitrile; (4) urea (7 1/2 lbs.) and stearic acid (15 lbs.) are heated rapidly until the urea is converted into cyanuric acid and then after 2 hours at 290 DEG  C. the product is filtered to obtain stearonitrile.  The Specification as open to inspection under Sect. 91 relates broadly to the preparation of aliphatic nitriles by heating urea and/or cyanuric acid with a high molecular weight fatty acid. This subject-matter does not appear in the Specification as accepted.

Abstract: 220,722. Igranic Electric Co., Ltd., and Rantzen, M. J. May 24, 1923. Selective distant control systews.-A number of electromagnetic devices e.g. relays have their magnets connected to a single circuit in such a manner that one or more of the devices can be selectively actuated by applying different potentials to the common circuit. The moving partsof the several devices are arranged in a row and adjacent devices are mechanically interlocked.. When a given potential is applied, those devices responsive to the given or a smaller potential move simultaneously, and when the applied potential is taken off all but one of the. displaced devices are returned to their former positions. The invention is described in connection with the distribution of power current to sections of a tramway system 13 - - 20 by means of remote controlled feeder pillars A, B', B<2>. The drawing shows diagrammatically the arrangement of a main feeder pillar A comprising four main switches 1 - - 4, and four relays 24 - - 27, the magnets of which are in parallel with one another and are connected in common to a supply conductor 12. Different potentials applied to the conductor 12 bv means of a switch 9 and a potentiometer 21 raise one or more of the relay contacts 24 -- 27 from the lower position shown in the drawing, the magnets being graded so that the first one 24 alone responds to a potential of 50 volts, the first and second respond to a potential of 100 volts, the first, second, and third to 150 volts, and all four to 200 volts. When the applied potential is taken off, the right-hand relay contact of those that were raised remains up .owing to the action of mechanical interlocks, the others falling back. By repeating the application of the potentiometer and switch, the arrangement allows one or more of the relays at will to be set and latched in the raised position. Magnets 28 for closing the main switches are in series with the respective relays and are subsequently energized through the conductor 12 by the a.pplication of full line voltage, disturbance of the graded relays being avoided by automatically cutting them out by a relay 37. A re-setting magnet 43 responsive to 250 volts gives the. means of restoring all the graded relays to their lower positions. Like arrangements apply to subsidiary distribution pillars B', B<2>.

Title: Improvements relating to cathodes for electron discharge tubes
IPC: H01J3/02
Filed: 1940-09-05
Abstract: 573,206. Thermionic cathodes. HARRIES, J. H. O. Sept. 5, 1940, No. 13886. [Class 39 (i)] [Also in Group XXII] A cathode for an electron discharge tube is formed by gripping a length of refractory wire, e.g. of tungsten, thoriated tungsten, or coated nickel, at a point near its centre and rotating the gripped part in one plane whilst restraining the end portions from rotation. A cathode of double flat spiral form, as shown in Fig. 5, is thus produced, which gives rise to substantially no magnetic field since the current flows in opposite directions in adjacent convolutions. The wire may be coiled by passing it through a slot in a pin A projecting from a rotating mandrel f into a hole in a fixed plate m, coiling taking place in the gap formed between the rotating face of the mandrel and the fixed surface of the plate. The turns may be spaced by a cotton or like covering on the wire, which is subsequently burnt off. When the wire is of tungsten or other material not easily formed into. shape, the spiral may be heated in hydrogen by stages to a temperature above the normal operating temperature and deformations corrected with a copper probe. Specifications 380,429, 385,968, 521,199 and 573,205 are referred to.

Abstract: 254,472. Western Electric Co., Ltd. (Western Electric Co., Inc.). May 28, 1925. Thermionic amplifiers, detectors, and modulating apparatus.-Thermionic valve circuits of the kind in which the effect of inter-electrode capacity is neutralized by a balancing capacity, are provided with additional means for preventing the production of parasitic oscillations. As shown in Fig. 2, the input circuit 18, 19 is connected on one side to the grid, and on the other side through the balancing capacity 15 to the plate, of the valve 10. Resistances 26, 26<1>, placed between the filament and the opposite ends of the input coil 19, serve to impede parasitic oscillations, and may also cause the valve to operate as a modulator or detector. The filament may be connected to a point between two variable condensers substituted for the condenser 18. In a modification, a single resistance is connected between the filament and the midpoint of the coil 19. Fig. 4 shows an arrangement in which a portion of the tuned input coil 17 is connected between grid and filament, and the plate circuit includes a high inductance 37 in series with the supply battery. These are shunted by a capacity 27<1> designed to give the output circuit a capacitative impedance at frequencies at which parasitic oscillations may occur. A capacity 36 connects the plate to a tuned circuit 22, the other side of which is connected to the grid through a capacity 15 for balancing the inter-electrode capacity, and to the filament through a capacity 28<1>. The input to the next valve 35 is connected across the two condensers 27<1>, 36 giving a step-up in voltage as compared with a connection made simply across the capacity 27<1>. In a modification, the balancing capacity 15 is connected between the free end of input coil 17 and the plate of the valve, and the lower end of the tuned circuit 22 is connected directly to the filament. The next valve 35 may be transformer-coupled to the circuit 22. Valves with equi-potential cathodes heated by induction or radiation may be employed.

[Class 38 (iv)] Voltage.-The field of an exciter is controlled by the output voltage of an alternator which it excites through a transductor, or saturable inductance, having a direct current magnetization depending upon the difference between a quantity derived from the output voltage and a standard quantity. This component of the excitation is opposed to a self or independent excitation and preferably also by a further component derived from the alternator. As shown, the exciter field winding 3 has a main component of excitation derived from its armature, an adjustable auxiliary and substantially constant component in the same sense derived from bus-bars 1 of an alternator (not shown) excited by the armature 2 and a regulating component in the opposite sense derived through a transductor winding 9 from the bus-bars 1. The winding 9 has opposed direct current saturating windings 10, 11 which are balanced at a desired bus-bar voltage. The current in winding 10 varies with this voltage and the current in winding 11 is rendered constant, for example as in Specification 479,834. Rectifiers 4, 5 couple the auxiliary and regulating elements to the field circuit and are shunted by resistances 6, 7. The transductor may have a self-fed reaction winding 16. Amplifying transductors may be introduced before the rectifier 5 and anti-hunting means may consist, for example, of a winding on the transductor or constant current device influenced by the exciter voltage through an impulse transformer.
