PURPOSE:To nullify the cost otherwise needed for cans etc. as well as eliminate the floor area to be used for storage of cans by stacking fiber fundles in layers along the axis without resorting to use of any core or can, and by retaining the shape through piling-up of adjoining fiber bundles in the said axial direction. CONSTITUTION:A tube wheel 13 revolves as a planet, while a tube 14 makes with...

In a pulverizer of the type having, within a casing, a stator and a rotor to be rotated in the stator, both having large numbers of mutually confronting ridges or teeth with a gap therebetween, the gap is 1 mm or less, and the ridges of the stator are of sawtooth shape as viewed in cross section and have flanks forming troughs therebetween with an acute bottom dihedral angle of 45 to 60 degrees. A...

A method of making a polyethylene terephthalate/polyolefin blend for sheeting and thermoformed articles which has improved color stability and can be recycled many times. A heat stabilizer is melt blended only with the polyolefin prior to its incorporation into the polyethylene terephthalate. The PET and polyolefin are then blended and extruded into sheeting and subsequently thermoformed into arti...

A metal powder-containing polymer composition selected from the group consisting of [A] polymer compositions each containing a metal powder having an amino compound and a silane coupling agent compound deposited thereon; and [B] compositions each consisting essentially of: (a) powder of a metal having an amino compound or a mixture of an amino compound and a silane coupling agent compound deposite...

A wholly aromatic copolyester composed mainly of isophthalic acid units and hydroquinone units, the total proportion of said isophthalic acid units and hydroquinone units being at least about 80 mole % based on the entire units, said wholly aromatic copolyester having a terminal carboxyl group concentration, measured by the method described in the specification, of not more than about 90 eq/106 g ...

A system is described for the production of rapidly solidified powder. The system contains elements for casting rapidly solidified ribbon, an in-line knife mill or a hammer mill for fracturing the rapidly solidified ribbon into shard, and either an in-line fluid energy mill, or an in-line centrifugal mill for reducing the shard to powder. The system can effectively reduce ribbon to powder in an in...

A memory (21) stores instructions which are addressed by an address register (26) and read into an instruction register (22). A decoder (23) decodes each instruction in the register and effects the necessary control operations via a control unit (24). The control unit in turn controls the execution logic (25) whereby the data processing operation required by the instruction is performed. A circuit...

Evaporated silicic-acid materials which have been pelletised at a particular speed of rotation are more easily transferred and handled and are outstandingly suitable for admixing to cement materials and/or concrete materials.

A process for the rapid post curing of polyether polyurethane foam in the form of porous blocks in which the foam is subjected to a mixture of water vapor and gaseous ammonia, primary or secondary amines at a temperature of about 50 DEG to 150 DEG F. for a period of 1 or more minutes. The cured foam recovers its original dimensions when distorted or compressed after the distortion or compression...

A rotatable drum (1) carries, and is driven by, a gear rim (3), with bevel toothing (12), via a flexible frustoconical casing (5) which accommodates distortions of the drum and absorbs axial loading resulting from the bevel toothing. Flexing of the gear rim is resisted on one side by the stiffness of the casing (5) and on the other side by a stiffening ring (9).

Improved reexpandable shrunken foam bodies of styrene-acrylonitrile type resin possessing an ability to reexpand to the original volume of the highly foamed state when left standing at room temperature under atmospheric pressure and a method for the manufacture of such reexpandable shrunken foam bodies. The aforementioned shrunken foam bodies are obtained by causing a styrene-acrylonitrile type re...

A leak detection device 5 is installed between the drill pipe 6 and test plug 4 of a casing seal arrangement. There is provided an outer seal 7 that separates test fluid B in contact with the casing seal 3 from the test fluid pressure source A. A slideable piston 10 is in contact with both fluid volumes A and B and will be forced downward if the lower volume B decreases for instance due to a leak....

A transmission control apparatus of an infinitely variable transmission (103) for electronically controlling the operation of the infinitely variable transmission (103) in response to transmission control information including a throttle opening position, etc., calculates a transmission operation command value by looking up a transmission control information-control command value conversion storag...

An optical communication system for drill hole logging comprises an armoured cable 58a containing one or more optical glass fibres 23a and 28 inside a tubular moisture barrier, a neodymium laser 21a capable of radiating infrared light into at least one of the glass fibres, a modulator 31 in a downhole cable-head connector shell 10a for modulating light and returning it to the surface, and a semico...

Digital data, for a computer or similar device, is encoded onto photographic film, paper, or other flat medium to be read optically by a data reader. The data reader may also read analogue data (such as pictures) in digital form. The data is stored in two-dimensional format, and read back by a point or one-dimensional scanner. The medium may typically be in the form of a strip, roll, card, disc or...

A differential lock control system controls a hydraulically-operated differential lock via a solenoid valve. Energization of the solenoid valve is controlled by a circuit which includes a normally closed latching relay, a normally open relay and a pair of operator-controlled momentary contact switches. The control circuit further includes a pair of steering valve-operated switches coupled in paral...
