Title: Improvements in or relating to thermo-magnetically operated devices
IPC: H05B1/02
Filed: 1927-05-16
Abstract: 295,667. Automatic Telephone Manufacturing Co., Ltd., and Roseby, P. N. May 16, 1927. Motors operating by thermally-produced changes of permeability of magnetic circuit.-The movable member of a thermo-magnetic motor is composed of material which loses its magnetic properties on heating, located in the field of a magnet and adapted to be heated electrically in one part of the field whereby the heated portion becomes nonmagnetic and the member is moved by the attraction between the magnet and the unheated portion. In a form of motor for producing a continuous reciprocating motion, sources of heat are located on opposite sides of the magnet and are rendered effective alternately as the movable member reaches the limit of its travel in either direction or a restoring spring may replace one of the heating coils. The invention may be applied to an electric relay in which the member performs a limited movement in one direction. As shown applied to a motor for continuously rotating a flicker device simulating the effect of a coal fire, a saucer shaper rotary member A of glass having an irregular surface carries a circle of tape or wire E on a non-magnetic frame F. A suitable material for the tape is a nickeliron alloy containing 30-40 per cent of nickel and preferably comprising 63 per cent iron and 37 per cent nickel, the alloy being annealed at a temperature of 300‹ C. Pure nickel may be employed. A permanent magnet preferably of cobalt steel or an electromagnet D is fixed with one of its poles near the tape and in close proximity thereto is located an electric heater B. The heater is in series with a lamp G disposed beneath the plate A. The tape in the vicinity of the heater B is heated above its critical temperature and the unequal forces produced by the magnet cause rotation. As the tape moves away from the heater, it cools and regains its magnetic properties whereby a continuous rotation results. According to the Provisional Specification, a flicker device for use in imitation fires comprises a cardboard or other cylinder closed at one end by a piece of glass or aluminium sheet having irregular holes, a glass cylinder, or a pair of glass cylinders rotating in the same direction at different speeds. The magnetic ring may be such that it loses its magnetic properties at ordinary temperatures and a cooling effect for restoring them is provided by an external source.

Title: Improvements in methods of making permanent magnets
IPC: H01F1/113
Filed: 1953-05-11
Abstract: 740,775. Magnetic structures. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. May 11, 1953 [May 14, 1952], No. 13144/53. Drawings to Specification. Class 38 (2). A permanent magnet is made by impregnating a sintered mixture of iron and cobalt oxides with a liquid which is solidified by heating while a magnetic field is applied to orientate the magnetic elements. Suitable impregnants are phenol - formol, formaldehyde, melamine, glycero-phthalate, ethoxyline and silicone resins, shellac and some natural gums, and .fatty varnishes. It is desirable to choose materials which harden at the most suitable temperature for magnetic orientation. An example is described, in which a ferrite body is impregnated under vacuum followed by pressure with a silicone varnish of high viscosity, the varnish being hardened at 300‹ C. for one hour, while a field of 3000 Oersteds is applied.

IPC: F16H1/22
Abstract: 132,227. Akt.-Ges. Brown, Boveri, et Cie. Sept. 5, 1918, [Convention date]. Driving-gear; pumping-machines. - Auxiliary pumps of steam-power installations are driven hy a common motor through suitable gearing so that each pump runs at its most economical speed. In the example shown, a turbine a drives a jet pump d direct, and a gear-wheel c through a pinion b. A cooling-water pump f is directly coupled to the shaft of the gear-wheel c. The condensed-water pump g and the feed-pump h are driven by pinions engaging the gear-wheel c. One feature of the invention is the placing of the condensed-water pump at a lower level than the remaining pumps for the purpose of increasing the head of admission.

Abstract: 425,511. Refrigerating. STEENSEN, S. J., 14, Damplass, Ullevaal Haveby, near Oslo, Norway. May 3, 1934, No. 13440. Convention date, May 3, 1933. [Class 29] Absorption machines and systems.-An absorption system comprises a condenser 3, liquid refrigerant reservoir 4, evaporator 6, absorber 7, and a combined generator and circulating pump 8 which communicates with the condenser either directly or through a vessel 1 containing a liquid or a solid absorbent, e.g. water or activated carbon. The pump includes a cylinder 15 connected by pipes 9, 29 to the absorber and the vessel 1 respectively and having a piston 17 rigidly connected by radial ribs 16 to a hollow plunger 12 provided with a non-return valve 14 at its upper end and working in a cylinder 11 having a non-return valve 10. The piston divides the cylinder 15 into a vapour space 20 and a strong liquor space 19 containing an electric heater 21. In the position shown, the pressure of the vapour generated in the space 19 maintains the valve 22 closed and forces the piston 17 upwards until the valve-spring 25 forces the valve open and permits the vapour in the space 19 to rush into the space 20. The consequent fall of pressure in the space 19 causes the piston 17 to move downwards under the tension of the copper bellows 18 and close the valve 22. During the upward motion of the piston strong liquor from the absorber flows past the valve 10 into the hollow plunger, and during the downward motion this liquor flows past the valve 14 into the space 19. Weak liquor flows continuously from the lower part of the space 19 to. the return pipe 35 of the absorber through a passage controlled by a throttle valve 31, the position of which is regulated by a bellows 33, the interior of which communicates through a passage 34 with the space 19.
