Title: Improvements in tungsten arc lamps
IPC: H01J61/54
Filed: 1924-06-16
Abstract: 226,481. General Electric Co., Ltd., (Assignees of Patent Treuhand Ges. f³r Elektrische Gl³hlampen). Dec. 21, 1923, [Convention date]. Arc lamps.-A tungsten anode h, Fig. 1, supported by a bimetallic strip bears against a spring-mounted auxiliary cathode, l while the lamp is not running. When current is switched on, the anode h moves for a short distance in contact with the auxiliary cathode, which is then arrested, 'for instance, by engagement with the end of the main cathode e. Further motion of the anode due to curvature of the bimetallic strip causes an arc to be struck and transferred to the main cathode e, the final position of the parts being shown in Fig. 2. The sliding contact between the anode and auxiliary cathode, which is preferably of polished tungsten, prevents these from fusing together. In another arrangement the auxiliary cathode is a perforated tungsten hemisphere sliding on the main cathode rod under the action of a helical spring; the range of the spring is adjusted, or a stop provided, to limit the motion of the hemisphere when current is switched on. In a third construction the rod cathode of Fig. 1 is replaced by a small block. A further arrangement comprises an auxiliary cathode in the form of a' disc rigidly secured to the main cathode rod, which is then carried by springs. An incandescent wire n serving as a series resistance is placed wholly or partly in the neighbourhood of the bimetallic strip k, which is also heated directly by passage of current. The anode support moves within a guide p. The cathode e may be of tungsten coated with thoria.

Title: Improvements in and relating to magnetic cores for stationary electrical induction apparatus
IPC: H01F27/245
Filed: 1953-05-26
Abstract: 731,215. Transformers. GENERAL ELECTRIC CO. May 26, 1953 [May 27, 1952], No. 14628/53. Class 38 (2). A three-phase three. legged core structure has the leg and yoke laminations split so as to form an outer core section separated by an air gap from an inner core section connection being made between the sections at the centre leg portion, all the joints between laminations being butt joints and adjacent lamina layers being shifted to produce overlapping joints with respect to the layers. A laminated core 1 comprises an outer core section 2 and an inner core section 3. The outer core section is formed of leg laminations 4, 6 and yoke laminations 12 ... 15 whilst the inner core section is formed of leg laminations 5, 7 and yoke laminations 16 ... 19. Thus, each leg and each yoke lamination of the core 1 is formed in two parts spaced apart from each other, such as 4, 5. Each laminaation of the centre leg is also formed in two parts 8, 9 which extend between the inner edges of the yoke laminations 16, 17 and 18, 19, the outer and inner core sections being connected by insert pieces 10, 11. The core 1 is built up in a three-step pattern repeated a plurality of times and in order to avoid the joint lines being coincident the successive lamination layers are shifted' so that the joints in successive layers are overlapped; whilst to remove coincidence in the joint lines of the insert pieces, the pieces 23... 25 (see Fig. 2) in one pattern are made successively wider. Each pattern may comprise any num. ber of steps and each layer may comprise a number of laminations. In a further embodi. ment the outer yoke members may extend the complete width of the core, the insert pieces then butting the inner edges of these members. In such an embodiment one or more of the insert pieces may be dispensed with the two parts of the centre leg laminations then extending between the yoke members. If more than one insert piece is dispensed with the centre leg laminations may be notched to receive the yoke members of the inner core section, which notches may be successively deeper in each pattern to provide overlap of the butt joints. Specifications 644,097 and 657,856 are referred to.

Abstract: 410,969. Gravity and inertia switches. SALMOND, H. M., Briarwood, Fareham, Hampshire. May 20, 1933, No. 14636. [Class 38 (v).] A switch for breaking the ignition circuit of a vehicle or craft on collision or over-turning, comprises an insulating tubular casing 2 mounted along the axis of travel of the vehicle and containing metal rings 4, 5 normally connected by resilient conductors 6 carried by a mass 7. The rings 4, 5 have a curved longitudinal section so as to retain the mass 7 in the position shown during normal acceleration but on collision from the front or rear, the mass 7 moves along the tube and the springs 6 break connection with one of the rings 4 or 5. The tube 2 terminates in a hollow disc 33 which is closed by a disc 28 leaving an annular channel which contains at the bottom some lead shot 21. These normally connect conducting plates 20, 29 but on over-turning they roll away to break the circuit. The plate 20 is connected to a terminal 23 to which one of the ignition leads is connected, and the plate 29 is connected to the ring 4 which is connected by springs 6 to ring 5 and terminal 24 to which the other ignition lead is connected. Thus on collision or overturning, the ignition circuit is broken. In modifications two tubes 2 are arranged at right angles to one another, and the metal balls may be replaced by mercury or by a pendulum.
