Title: Improvements in the manufacture of light-diffusing glass
IPC: C03C12/00
Filed: 1928-02-09
Abstract: 287,545. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) March 24, 1927, [Convention date]. Production of metal; forming electric lamp bulbs.-A method of making light-diffusing glass, particularly suitable for electric lamp bulbs, consists in pulverizing clear glass and then fusing the pulverized material to form a viscous mass which is blown to the desired shape. The air bubbles enclosed in the viscous mass cause the finished glass to be turbid and of an opalescent appearance. The raw glass is pulverized in a ball mill, and it may be compressed into bodies of predetermined size before being fused. The fused mass may be blown in the usual way, or a quantity may be gathered in the end of a glass tube which is used as a blowpipe and may also supply part of the finished bulb, such as the neck. Colouring or opacifying agents may be added to the pulverized mass before it is fused.

Abstract: 1,179,392. Aerials. MINISTER OF TECHNOLOGY. 27 Jan., 1967 [31 Jan., 1966], No. 4117/66. Heading H4A. A conical electromagnetic horn has an oval cross-section in a plane at right angles to its central axis. The oval cross-section is symmetrical about its major axis and about its orthogonal minor axis, and may be elliptical. A means such as a rectangular waveguide is connected to the apex of the horn, to which it couples plane polarized waves having their electric field vectors disposed substantially at 45 degrees to the aforesaid major axis. It is stated that the radiation diagrams of the horn measured in two planes at right angles to each other are nearly the same and are substantially independent of the frequency of excitation, and that side lobes are reduced. Adjustment is possible by deforming the conical horn to alter the aspect ratio (major axis/minor axis) of its cross-section.

Title: Improvements in or relating to electric systems for controlling the position of a controlled object
IPC: G05D3/12
Filed: 1936-02-15
Abstract: 473,753. Electric control systems. SPERRY GYROSCOPE CO., Inc. Feb. 15, 1936, No. 4647. Convention date, Feb. 16, 1935. [Class 40 (i)] In an electric remote control system of the resultant field type, disagreement between the positions of the controlled and controlling means during operation is eliminated by introducing into the system a correcting signal which depends upon the acceleration or deceleration of the controlling means with respect to the controlled object. As shown in Fig. 1, a hand wheel 1 controls the position of a polyphase rotor 4 in an alternating field produced by a stator 6. Movement of the rotor 4 causes a corresponding angular shifting of the magnetic field in the rotor 9 of the receiver, the rotor co-operating with a stator winding 11 in such a manner that the induced voltage varies between zero and a maximum according to the position of the field in the rotor. The output of the winding 11 is divided between two circuits 60, 20 the former of which produces an e.m.f. proportional to the angular displacement between the rotors 4, 9 whilst the latter produces an e.m.f. proportional to acceleration. These e.m.f's. are combined in the output of the transformer 58 and effect operation of the motor 14 and controlled object until the rotor 9 driven by the motor is moved into the position of zero voltage in the winding 11. The circuit 20 is connected 'to a transformer 19 the output of which is applied to phase detector tubes 23, 24 arranged so that current flows in the output circuit of one or other tube depending upon the phase relation of the signal, i.e. upon whether the hand wheel is turned in one or other direction. The output of the tubes is passed through a filter 36 .. 40 and is applied as a unidirectional e.m.f. to a condenser 41 connected in series with a transformer 48. The arrangement of condenser 41 and transformer 48 serves as an acceleration or deceleration detector, and the output of the transformer 48 is applied to oppositely connected modulator tubes 44, 45 which supply a transformer 52, the secondary of which is connected in the circuit 60 and together with resistances 66, 62 and transformer 58. forms a bridge circuit. The displacement signal supplied from the stator 11 and applied directly to the circuit 60 is additive to the signal corresponding to acceleration and derived from circuit 20. The output of the transformer 58 is applied through amplifiers 71, 72 and rectifiers 79, 80 to the control windings of a repulsion motor 14 which operates a controlled object 2 and also rotates the rotor 9. In a modification, the repulsion motor is replaced by an A.C. series motor.
