Title: An arrangement in asynchronous machines with commutator machines mounted in cascade
IPC: H02K17/38
Filed: 1928-04-03
Abstract: 288,630. Siemens -Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). April 14, 1927, [Convention date]. Alternating-current induction machines.-In a group comprising an asynchronous machine cascaded with a series commutator machine the excitation circuit of which is so arranged as to cause it to introduce into the secondary of the asynchronous machine two voltage components one of which increases with the slip and neutralizes the secondary voltage and the other produces the loading current in known manner, additional means are provided in the exciting circuit of the commutating machine for injecting voltages for neutralizing the effect on the primary and secondary loading current of at least the first of the following three voltages in the asynchronous machine :-The inductive dispersive voltages in (i) the secondary and (ii) the primary circuit and (iii) ohmic drop in the primary circuit. The primary current of the asynchronous machine is thereby made proportional to the regulating voltage fed to the exciting circuit of the commutator machine and the loading current of the asynchronous machine may thus be rendered strictly independent of its slip. The Specification contains mathematical investigations showing how this result is given by the arrangements shown in Figs. 1 and 2. In Fig. 1 the compensated commutator machine 2 is cascaded with the asynchronous machine 1 and is excited through the usual variable transformer T. A current transformer 3, preferably designed for a large magnetizing current, is included between the two machines, the secondary voltage of which is added, directly or through a frequency changer 4 and transformer 5, to that of the transformer T. In this circuit is also included the rotor of an asynchronous machine 6 the stator of which is fed with the resultant voltage from the series-connected secondaries of two transformers 8, 7 connected respectively on the line and in series with the stator of the asynchronous machine 1. The two current transformers 8, 7 and the asynchronous machine 6 may be omitted, as shown in Fig. 2, in which case the secondary side of the transformer 3 is connected to an auxiliary winding H on the machine 1. It is shown in the Specification that the illustrated connections cause the terminal voltage of a cascaded exciter, such as the machine 2 mechanically coupled to an asynchronous machine 1, to remain constant independently of the slip of the machine 1. By designing the transformer 3 with certain characteristics which are explained in the Specification, the load current of the machine 1 may be made to vary with its speed. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention is specially applicable to cascade sets which couple networks with variable periodicity. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to deflection members for cathode-ray tubes
IPC: H01J29/76
Filed: 1951-05-02
Abstract: 687,762. Cathode-ray tubes. PHILCO CORPORATION. May 2, 1951 [May 26, 1950], No. 10310/51. Class 39(i) A deflecting coil for a wide-angle cathode-ray tube comprises a plurality of turns of wire arranged in the form of lumped conductors-two longitudinal conductors 28, 30 spaced a greater distance from the axis and from each other at one end than at the other, and bent convexly towards the axis throughout at least a portion of their length, and two end conductors 32, 34 disposed transversely of the axis so as to exert relatively less deflecting effect than the side conductors. Theoretically it is shown to be preferable for the convex portions of the side conductors to lie in the surface of a hyperboloid of revolution, but in practice they may lie in a surface of revolution which intersects a longitudinal plane through the axis in sectors of a circle. The coils may, however, lie in a surface of rectangular cross-section. The end conductors lie in the same surface of revolution as the side conductors. The turns of wire for each pair of oppositelydisposed deflecting coils, in a deflecting assembly consisting of two pairs of coils 12,a, 12b, Fig. 4, are so distributed that their concentration, in transverse cross-section, is a maximum at two points 180 degrees apart, the concentration of turns decreasing progressively from either of these points to a minimum at points angularly spaced 90 degrees to the points of maximum number. The circumferential turns distribution varies. however, throughout the length of each coil, being proportional to the cosine of the angle from the points of maximum number, at one end of the coil, and proportional to the cosine squared of such angle, at the other end of the coil. In this way a uniform magnetic field is provided at the gun end of the coil, and a non-uniform field for correcting pin-cushion distortion without defocusing the cathode-ray beam or distorting its crosssection, is provided at the screen end of the coil. Instead of varying the turns distribution of the individual coils, spacers may be inserted between the coils, so that the distance between them varies from one end of the structure to the other. The coils may lie in a cylindrical surface over a portion of their length at the gun end. A flux return path may be provided by a number of turns of wire arranged in helical form, and overlying the outer deflecting coil units.
