The invention relates to a clutch brake and a method for its manufacture. A metal powder is pressed into the required form for each of a pair of opposing covers. The form of the blank has a plurality of raised segments, which are arranged in an annular series. Each blank is sintered in a sintering furnace. During the sintering the relatively porous blank can be impregnated with another material in...

Dispersions of hydrophobic substance eg resin emulsions, usually having a relatively low average particle size can be continuously and speedily prepared by feed a hydrophobic substance in the liquid state into at least two static mixers, arranged in a series. The resin is introduced at a temperature above 50 degrees C but below its degradation temperature of hydrophobic substance and water under p...

A switchable permanent magnet eddy current or track brake which has a high density of permanent magnet material, a low internal flux leakage and a higher than heretofore output flux density. The pole shoes of the movable magnets are convex cylindrical segment-shaped and mate with concave cylindrical segment-shaped recesses in the lateral flux return pieces for the fixed magnets.

The process is for the preparation of aqueous emulsions of phenolic resins and phenol-modified hard resins. In the preparation, the hard resin is melted in the presence of a water-immiscible solvent, anionic emulsifiers are added, and water is then added at the melting point to above the inversion point. The resultant oil/water emulsion is further diluted with water to the desired solids content. ...

Membranes of highly crystalline PTFE having an average pore size between about 0.01 micron and about 0.5 micron ordinarily reject any passage of water while allowing an organic nonpolar liquid to flow therethrough. By thoroughly wetting an expanded polytetrafluroethylene membrane with isopropyl alcohol, such a membrane will selectively allow the passage of a polar liquid, for example water, theret...

An apparatus and method are described for producing compact stranded conductors on single and double twist machines. This is achieved by pre-shaping and metering the preshaped wires to have generally sectored cross-sectional profiled complementary configurations and positioning and orienting the preshaped wires to substantially correspond to their positions and orientations in relation to the core...

HEAT RESISTANT PRECOATED STEEL SHEET AND PROCESS FOR THE PRODUCTION THEREOF A heat resistant precoated steel sheet suitable for use in the manufacture of a muffler of an automobile exhaust gas system comprising: a hot dip aluminized steel sheet, a chromate pretreatment layer formed on at least one surface of said hot dip aluminized steel sheet and having a chromium pick -up of 10 to 50 mg/m2, a pr...

The device is for sorting out a multiplicity of pieces such as tickets according to their size, and comprises a cylindrical sorter drum (10, 26, 29, 35, 43, 46, 61, 70, 95) rotatably mounted in a frame (1) for storing therein pieces (A, B, C) to be sorted having different sizes. The sorter drum is provided with means including openings (21, 42, 44, 52, 64, 72, 98, 99) for passing therethrough piec...

A connecting plug for use in conjunction with standard electrical boxes and circuit components such as switches and receptacles. The connecting plug includes a insulator block attached by a grounding screw to the back panel of an electrical box. Rigid contact pins extend outwardly from the insulator block a predetermined distance so that they will be releasably received in the openings in the body...

Corrosion inhibiting compositions for addition to aqueous acid metal cleaning compositions for use in the cleaning of surfaces of metal parts which are contaminated with water insoluble, acid soluble deposits, wherein the corrosion inhibiting composition contains a partially hydrolyzed protein which is either a partially hydrolyzed gelatin, a partially hydrolyzed casein or a mixture thereof wherei...

A multicolor luminescent article comprises a layer of a first luminescent semiconductor having a discontinuous layer, pattern or image comprised of a second luminescent semiconductor on at least one surface thereof.

This pipeline processor has an ALU, an accumulator register, a first data bus connected through a first switch circuit to output terminals of the accumulator register, and a second data bus connected to input terminals of the accumulator register through a second switch circuit. Data on the first data base is processed by the ALU, and supplied through a third switch circuit to the second data bus....

Associative keys and retrieve outputs corresponding thereto are registered to an associative memory in a vector data conversion apparatus. Conversion vector data stored in the main storage and comprising vector elements of the same type of an associative key is sequentially read out for each vector element and is inputted to a comparator, which then compares the vector element with the associative...

A cutting tool, preferably in the form of a scalpel, microtome or razor blade is fabricated from single crystal material such as aluminum oxide with a preferential etching process to produce a radius of curvature less than 100 Angstroms on the edge. Depending upon the etchant, the crystallographic orientation of the blank and the resulting different etch rates on blade surfaces, the preferential e...

DENTAL COMPOSITE AND PORCELAIN REPAIR A filled-resin composition useful for porcelain repair and as a dental composite and therefore made up of non-toxic materials and a method for repairing porcelain or teeth. The composition comprises a methacrylate functional resin usable in dental composites, powdered filler-colorant therein, at least one photoinitiator for the resin in an amount sufficient to...

In a fully-automated washer, a cloth amount sensor detects a quantity of an object being washed as a value inclusive of information regarding a degree of bulkiness of the object to be washed. A processing circuit is responsive to a detection output signal from the cloth amount sensor to determine a water supply amount, a cleanser feed amount, a stirring or agitating time and a rinsing time. The cl...

A nuclear magnetic resonance tomography apparatus generates a tomographic image substantially free from artifacts caused by body movement, such as respiration, during acquisition of the tomography signals. The tomography signals are acquired and stored in the form of Fourier lines in an image matrix. For reducing image artifacts, a control unit is provided for controlling entry of the acquired tom...

A process for the purification of effluent, in which the effluent to be purified is first introduced into a high-loaded activation stage operated as an adsorption stage, then is passed through an intermediate clarifier with sludge offtake and subsequently introduced into a low-loaded stage to which a final clarification stage with sludge offtake is connected. Microorganisms work in the adsorption ...
