Patent GB-892934-A (GB)
Title: Casting complex structures with foamed metal core and solid skin
IPC: C22C1/08
Filed: 1960-01-01
Abstract: 892,934. Metal foams. LOR CORPORATION. Jan. 1, 1960 [Jan. 5, 1959], No. 120/60. Class 82(1). [Also in Groups XIV, XXII and XXXIII] A molten metal intermixed with a substance thermally caused to form a gas at the melting point of said metal is introduced into a mould before foaming has taken place, the inner surface of the mould having a temperature sufficiently low to cause solidification of a skin of said metal which is not remelted or foamed, so as to form an article having a substantially rion-porous skin and a low density core. In one embodiment, Fig. 3, the metal container 20 is held under a pressure sufficient to repressthe foaming action, the mixture being agitated by mechanical or electromagnetic means 21. The mixture is then fed to the mould 22 under pressure or so rapidly that foaming does not occur until the pressure is fully released in the mould. Foaming agents referred to for low melting point metals such as Al, Mg, Zn, Pb &c. are metal hydrides such as Ti, Zr, Li, Li-Al and Mg, carbonates such as Na 2 CO 3  and NaHCO 3 , stable hydrates such as chromium oxide hydrate, and decomposable organic materials such as phthalocyanine and silicon products. For high melting point metals such as the ferrous metals and alloys, Ni, Co, Ti, Zr, Nb may be mixed with a lower melting point metal such as Zn, Ca, Li, Mg, the ebullition being repressed by pressure while mixing, sudden release of the pressure then causing the low melting point metal to become gas. Cu and its alloys may be formed by either of the above methods. In one example, 90% of an alloy, 33% Mg, 67% Al, is mixed with 10% zirconium hydride at a temperature of 465C. and the mixture then injected into a stream of molten aluminium in a ratio 1 : 9 and the metal cast into a cold sand mould before foaming commences. In another example, 1 part titanium hydride powder and 12 parts Al powder enclosed in an Al container is dumped in 200 parts of molten Al at 675-680C, which is then cast in a pressurised mould heated to 500C. In a further example 0À1 Kg of zirconium hydride mixed with 1À2 Kg of Al powder in Al tubing is introduced into violently stirred molten Al which is then cast into shell moulds. Specification 729,339 is referred to.

Title: Improvements in or relating to motor operated valves
IPC: F16K31/04
Filed: 1935-01-08
Abstract: 442,321. Automatic control of temperature or pressure. BRITISH THERMOSTAT CO., Ltd., Windmill Road, Sunbury, Middlesex, and PAYNE, M., 50, Hook Road, Surbiton, Surrey. Jan. 8, 1935, No. 687. [Class 38 (iv)] [See also Group XXIX] A lift valve 2 operated by a reversible electric motor 12 through a gear train and an oscillating crank-pin or eccentric, is controlled by a thermostatically or pressure actuated switch mechanism. The motor 12 is housed in a casing 5 formed with an extension 29 in which is mounted a metal bellows or expansible chamber sensitive to thermostatic or pressure changes so as tc move an arm 30 about a pivot 33 against the action of an adjustable spring 31. Yieldably clamped to the arm 30 by springs 46 are two fingers 42 carrying contacts 43, 44 co-operating alternatively with contacts 48, 49 on a finger 47 carried by a bell-crank lever 51 connected to the valve head 8 by a pin-and-slot connection 53. Engagement of one or other of the pairs of contacts 43, 44 or 44, 49 reverses the field connections and therefore the direction of rotation of the motor 12, the motor being at rest when the finger 47 is in an intermediate position between the fingers 42. A rise of temperature or pressure causes engagement of the contacts 43, 48 and rotation of the motor to close the valve, this movement of the valve causing the finger 47 to move away from the contact 48 and stop the motor, a fall of temperature causing a reverse action through the contacts 44, 49. The finger 47 may be mounted on the arm 30 and the fingers 42 on the lever 51. The bellows chamber may be utilized to open the valve as it expands and . close it as it contracts. The motor 12 is designed so that it may be left in a stalled condition without damage and its torque relied on to keep the valve in either of its extreme positions when such position is reached. The valve may be controlled by a thermostatically or pressure - operated switch mechanism as described in Specification 435,083, [Group XXIX].

Title: Motor and method of controlling it
Inventor: GUERIN YVES
IPC: H02K16/02
Filed: 1993-03-11
Abstract: The motor unit comprises a stator, two independent rotors having each a permanent magnet located in a cylindrical space defined by three pole faces of the stator, two windings and at least a positioning magnet for holding both rotors, in the absence of current in the windings, in a position in which the magnetic axes of their magnets are each coincident with a rest axis. The field produced by the flow of a current in one of the windings is always at an obtuse angle to one of the rest axes and at an acute angle to the other. The two rotors perform steps of 360 DEG  independently of each other in response to pairs of current pulses, the first of which is applied to one of the windings and the second of which is applied to the other winding. The direction of the current pulses determines which of the rotors performs a step, and the order in which the current pulses are applied to the windings determines the direction of rotation of that rotor. The motor unit can be used in particular in an electronic timepiece.

Abstract: PURPOSE:To measure the inclined angle of a picture at high speed even if the number of characters for one line is small or the characters different in size are mixed in one line. CONSTITUTION:The picture where only a character part is separated and binarized is raster-scanned, and labels (1, 2, 3...9) are sequentially given to the respective characters in the order of scan. Common and specified picture elements among the set of picture elements constituting the respective characters are set to be positions representing the respective characters, and the positions are obtained as the coordinates (a, b, c,...i) of a raster. Then, the respective coordinates of adjacent label numbers are connected by segments (a-b, b-c,...h-i), and the histogram of the inclined angles of the respective segments is obtained. The average value of the inclined angles in a section where the frequency of the histogram is maximum is obtained, and it is set to be the inclined angle of the picture. (The parts of the segments c-d and f-g are excluded).
