Title: Improvements in preparation of ferromagnetic ferrite materials
IPC: H01F1/03
Filed: 1958-10-06
Abstract: 891,131. Magnetic compositions. GENERAL ELECTRIC CO. Oct. 6, 1958 [Oct. 8, 1957], No. 31820/58. Class 38 (2). In the manufacture of ferromagnetic ferrites, cooling after sintering (or reheating) takes place in an atmosphere whose oxygen content is changed so that the oxygen content of the ferrite is maintained constant during cooling. Ferrites with a spinel structure may be produced whose oxygen content is greater than that in the ideal ferrite whose formula is MFe 2 O 4 . The upper boundary AA<SP>1</SP>, Fig. 5, indicates the variation of oxygen content with cooling temperature that must exist for the ideal ferrite to be produced. Above this line and below the line BB<SP>1</SP> spinel structures are not attainable. Between these lines spinels having various amounts of excess oxygen are possible, the lines indicating cooling curves of constant oxygen content along which no oxygen exchange takes place. The Specification discloses considerable data relating to experiments on MgMn, MnZn and NiZn ferrites. Reference has been directed by the Comptroller to Specification 674,828.

Title: Improvements in secondary emission electron multipliers
IPC: H01J9/12
Filed: 1937-02-03
Abstract: 487,899. Electron multipliers. GENERAL ELECTRIC CO., Ltd., SIMMS, C. H., and TRELOAR, L. R. G. Feb. 3, 1937, No. 3198. Drawings to Specification. [Class 39 (i)] In secondary emission electron multipliers of the type having a photo-electric primary cathode and in which the electrons are guided by co-operating electrostatic and magnetic fields, the cathodes are made of silver plates and the surface of the primary cathode is much less highly polished than the secondary cathodes before the oxidation process which precedes sensitization. To obtain uniformity of oxidation of the polished secondary cathode plates, it is preferred that they should be oxidized once and then heated to about 300‹ C., to decompose the oxide, the process being repeated one or more times; or they may be heated in oxygen at a pressure of about 1 m.m. at 400‹ C. for an hour. The treatment must not be so severe as to destroy the polish of the secondary cathode plates relatively to the primary cathode. In one embodiment, the plates are assembled as described in Specification 478,262. The primary plate is etched with 50 per cent solution of pure nitric acid and washed and the secondary plates are all highly polished. After assembly, the tube is evacuated at 400‹ C. Oxygen is then admitted at 1 m.m. pressure, and the device heated for 15 minutes at 400 C. The oxygen is evacuated and the multiplier cooled. Fresh oxygen is then introduced at a pressure of À7 m.m. and the surface of each electrode oxidized by electric discharge so that it assumes a green colour. The oxygen is then pumped away and the temperature allowed to reach 200‹ C. and maintained while caesium is introduced until the sensitization has reached the desired point.

As shown the roll 9 is removably mounted by spigots 6, 7 in a frame 1 which carries adjustable clamping jaws 2, 2 releasably attached to a vertical slide 3 on the mast 4 of a fork-lift truck 5 and a pair of nip rollers 10, 11 which are preferably rubber-faced and made of steel respectively, the roller 10 being manually rotatable by a hand wheel 12. A flexible brake band 15, anchored at one end to the frame 1 and at the other end to a pivoted, brake-applying lever 16 loaded by a spring 18, passes round brake drums 13, 14 which are mounted respectively on the upper ends of the shafts of the rollers 10, 11. A film-guide roller 21 is mounted at each side of the frame 1. In use an operator, by manipulating the handle 12, feeds the leading end of the film web through the nip between the rollers 10, 11, around the appropriate roller 21, and then attaches it to the article to be banded such as a palleted load of cartons 22. The friction brake 13-15 is released by operating a rod 19 and the truck 5 is then driven completely around the load 22 to overlap, and trap, the leading end of the web film whereupon the brake is applied and the truck is driven around the load to apply as many layers of stretched film covering as required. The web film is finally cut and taped, or heat-sealed in position. Helical wrapping can be achieved by synchronizing vertical movements of the slide 3 with the pay out of the web film as banding proceeds. The wrapping attachment may be incorporated as a permanent feature of an automotive vehicle.

Abstract: 922,295. Hot axle-box detectors. SOCIETE ANONYME DE TELECOMMUNICATIONS, and COMPAGNIE DE SIGNAUX ET D'- ENTREPRISES ELECTRIQUES. Jan. 31, 1961 [Feb. 1, 1960], No. 3724/61. Class 40 (3). [Also in Group XX] A stationary hot axlebox detector comprises an indium antimonide cell on to which the radiation from the hot boxes is focused. The radiation beam is modulated by a chopper disc. By means of a calcium fluoride lens 1 and a band-pass filter 2 radiation only of wavelengths 5-9 microns passes to the cell 4, thus reducing the effect of ambient solar radiation on the cell. A perforated disc 3 is rotated at high speed to modulate the radiation beam. The pulses from the cell are of short duration for a fast-moving vehicle so, after amplification, the pulses are elongated in a pulse-stretching unit 7. The signals then pass to a relay 9 which can trigger an alarm, and to a temperature recording device 8. In a second embodiment the cell output is mixed with a high-frequency signal in a ring modulator, the chopper disc 3 being rotated at low speed and the difference frequency signal being eliminated before amplification and utilization.

Abstract: 1,170,071. Digital data store. SOLARTRON ELECTRONIC GROUP Ltd. 12 Jan., 1967 [28 Jan., 1966], No. 3984/66. Headings G4A and G4C. [Also in Division H3] A digital information store includes a number of interrogation wires, a plurality of members of magnetic material, each looping selected interrogation wires but not others according to the address of a word in the store, and a number of output wires each of which is looped by one or more of the members. A permanent store (Fig. 3) card comprises an entry blank 16 cut away to represent an address and a stored word. The blank has an elongated aperture 13 and a plurality of holes arranged between the aperture and one edge, parallel to the longitudinal axis of the aperture. The blank is then cut away to form slots which loop some of the interrogation wires passed through the holes. In operation, a part or parts of the magnetic material all on the cards but one is saturated by passing currents through the wires which are not looped by the selected card, e.g. for five interrogation wires three wires may be looped by each card and two not looped giving a choice of ten cards any of which can be chosen. A pulse or burst of sinusoidal oscillation is passed through an additional wire passing through all the cards to induce a signal on the appropriate output wires, the variation not being sufficient to take the other cards out of saturation. Alternatively the address of cards carrying specific data may be read out by pulsing appropriate output lines. A temporary store card (Fig. 7) has the apertures and slots of the permanent store card but has a further slot 20 and a set of holes 21, 22. A wire threads slot 20 and is used to set the card to one magnetic state or the other. A word is entered in the store by passing currents through wires threading the set of holes 21, 22, the magnitude of the currents being half that required to make the material change its state. The currents passed by wires in slots such as 34, 35 ensure that in all cards but one the net current passed through a slot 36 opposes the current through the slot 30. In the selected card the current passing causes the card to revert to its initial state and causes, pulses to be induced in appropriate read-out wires.

[Class 38 (v)] A bus-bar system 3, preferably of the metalclad type subject to earth-faults only, is protected against such faults by a biassed differential relay 15, the operating winding 1A of which is energized by the total unbalance from current-transformer groups 10 -. 13 in all the circuits connected to the bars, whereas the restraining winding 22 is energized by the total resultant neutral-to-earth current from current transformers 20, 21 in one or more connections 18, 19 of generators 1, 2, and in series with the coil 23 of an earth-leakage relay having its contacts 26 in series with contacts 25 of the differential relay in a master trip-circuit for all the breakers. With earth-faults on the bars 3, winding 1A overpowers winding 22 and, as 26 also close, tripping results. With external earth-faults, the out-of-balance current in 1A, due to saturation, is insufficient to close 25, so no tripping occurs. With external phasefaults, 23 does not close 26, so again no tripping occurs.
