Patent IE-830378-L (IE)
Title: Semiconductor memory
IPC: G11C11/415
Filed: 1983-02-23
Abstract: A semiconductor memory includes a dynamic discharge circuit for the quick discharging of a power supply line to which a memory matrix row is connected when this power supply line changes over from the electrical selected state to the electrical rest state. A transistor which is rendered conductive by a dynamic potential difference which arises, due to the slow discharge of the power supply line, between this line and the selection circuit thereof, supplies a current for a brief period of time in order to achieve the quick discharging. The invention is typically used notably for the discharging of power supply lines of E.C.L.-type random access memories.

Abstract: 1,202,829. Needle felt. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 21 April, 1969 [22 April, 1968], No. 20150/69. Heading D1R. Needle felt having a high mechanical strength a dimensional stability is produced by working with needles or pins one or more fibrous webs obtained by fibrillating a film predominantly consisting of polypropylene. Preferably the fibres of the web are mainly interconnected to form a network. Alternatively the web may consist completely of loose fibres. Suitably stretching ratios of the film before fibrillation are between 1:3 and 1:20 and a thickness of 0.01-0.2 mm is usual. Needling may be applied to a stack of fibrous webs in which all the webs are orientated in the same or different directions. Binding agents such as pulverulent polyethylene may be applied before or after needling. A web of crimped fibres may be obtained by the fibrillation of laminates in which all the layers are polypropylene or some are e.g. polyethylene, copolymers of propylene and ethylene, polyesters and polyamides.

Abstract: 1487411 Froth flotation ALLIED COLLOIDS Ltd 14 Nov 1975 [19 Nov 1974] 49981/74 Heading B2H Pyrites, pyrrhotite, and/or sphalerite are depressed during froth flotation by an amine in which at least 20% of the amine groups are tertiary amine groups, with quaternary amine groups absent or present to a number less than one third that of the tertiary amine groups. The depressant may be monomeric e.g. a vinyl pyridine, triethanolamine, ethylene diamine tetra-acetic acid, an alkylated diethylene triamine, or a dialkylaminoalkyl acrylate or methacrylate. The amine may be a polymer e.g. a dialkyl aminoalkyl cellulose, a polyvinyl pyridine, an alkylated polyethyleneimine, a condensation product of a dibasic carboxylic acid with a polyalkylene polyamine (for example adipic acid with diethylene triamine treated with an alkylating agent such as dimethyl sulphate or a cross-linking agent such as epichlorhydrin) or a polymer derived from a dialkyl aminoalkyl acrylate or methacrylate or acrylamide. The alkyl groups contain 1-8 carbon atoms, preferably 1-4. Dialkyl thionocarbamates may be used as collectors at a pH of 8-12, using methyl isobutyl carbinol, pine oil, or polypropylene oxides as frothing agents. The process may be used during flotation of sulphide minerals from ore, and during separation of metal values from the "bulk sulphides" so produced. Other depressants may be used at the same time, e.g. soluble silicates, lignosulphonates, and cyanide salts. If desired, the pyrites or pyrrhotite together with sphalerite may be depressed, and the sphalerite subsequently floated in the presence of an activator therefor, e.g. copper sulphate or lead nitrate. Examples are given of beneficiation of copper, zinc, lead, and nickel bearing ores in two or three stages.

Abstract: A synchronous ac electrical motor comprising (A) a stator (20) having a body slotted (30), soft ferromagnetic, low eddy to produce a rotating magnetic field, an excitation coil (32) energizable with single phase ac located in two adjacent slots with a pole piece between them, and feedback windings (33) located in slots such that when ac potential therefrom is conveyed to the excitation coil the excitation ac is modified to a selected phase and magnitude to improve the "pull in" torque of the motor, a capacitor (94) containing circuit connecting the feedback windings and the excitation coil, the body of ferromagnetic material having a cylindrical surface, and the improvement characterized in that (B) a rotor (40) has three major components electrically and magnetically associated, (1) first being an exterior layer (52) low electrical conductivity magnetizable permanent magnetic material having an outside cylindrical surface complementary to that of the stator, (2) a high-permeability, low eddy current component (44) to which the first layer is attached, and (3) the third component (48) being a supporting body of ferromagnetic material of high permeability and high electrical conductivity on which the second component and first layer are fixedly supported. The third component can be a solid ring of steel, for example, or it can be a laminated core containing shorted electrical conductors. In starting from standstill, the power windings and energized with ac power and this produces a circulating electrical current with the third component of the rotor which reacts to produce rotational torque. After the rotor reaches about 70 to 80% of synchronous speed, the excitation coil is energized and this will produce strong alternating magnetic flux in the pole piece (34) which magnetizes the layer of the permanent magnetic material into a pattern of north and south magnetic poles in the proper phase with the rotating field of the stator so as to produce a powerful rotational torque that accelerates the rotor to a predetermined synchronous speed.
