A fluidized bed reactor is provided with heat exchange coils for controllng the temperature of the fluidized bed. The heat exchange coils are vertically oriented and elements thereof pass through the constriction plate of the reactor. Multiple function Tuyere elements are provided which admit air into the reaction chamber from the windbox, provide for passage of elements of the heat exchange coils...

For the manufacture of non-wovens, filaments are laid down on a moving surface. The filaments are deflected by means of a rotating deflector and a subsequent guide plate connected thereto. It is important that the rotating deflector deflects the filaments from the rotational axis and that the guide plate rotating synchronously with the deflector leads back at least part of the filaments in the dir...

A module for applying a magnetic stripe character to a plastic card. A tiltable carriage moves the card along a transfer path past magnetic code applying apparatus when tilted in a first position. When the carriage is tilted into a second position, it returns along the transfer path to engage a further card while the first card is removed from the card transfer path by pinch rollers driven by a un...

PURPOSE:To provide the title reactor so designed that a fluidized bed is equipped with an inner cylindrical tube into a double tubular structure to feed, as each fluidizing gas, a high-concentration fluorine gas into the inner cylindrical tube and a unreacted exhaust gas into the outer cylindrical tube, thereby improving the treating speed and yield of UF4, improving the utilizing efficiency for t...

Water containing refractories which inhibit or eliminate the tendency of explosive spalling are provided by mixing solid organic fibers into the refractory mix. The refractory mix may be used in castables, plastics, ramming or gunning mixes or mortars.

A power control circuit, such as a lamp dimmer, has a load connected in series with a bridge rectifier (GL) (Fig 1), across a supply, FET T1 connects across a diagonal of the bridge (FL) and turned on at each zero-crossing of the supply and turned off by a monostable M at an adjustable time in each supply half-cycle, and circuit elements R1, R2 C1, C2 which cause the FET T1 to turn off gradually w...

A gelling agent is added to a fast setting cement slurry comprising water, cement and anti-washout retarder and the mix is injected into a void containing running water and allowed to set to form rapidly a material of high compressive strength.

The present invention relates to an Expert System (ES) shell that diagnoses computer performance problems. The object of the invention is to present to a system programmer a set of possible diagnoses for a performance problem, including variables derived from measurement data that either favor or refute the diagnosis in question. The system comprises a knowledge data base, and an 'inference engine...

New compounds useful as therapeutical agents and useful as intermediates for the preparation of other therapeutically active di-hydropyridines, which new compounds are of the formula wherein R<1> in one or two (the same or different) substituents on the phenyl ring selected from the group consisting of NO2, Cl and lower alkyl; R is -CH3, -CHO or wherein R<1><1> and R<1><2> are same o...

A compression anastomosis assembly (10) of, interlocking coupling members (12, 22, 32), particularly suitable for use in achieving anastomosis of tubular organs, having an improved locking feature to prevent inadvertent disassembly of installed coupled members. The design and configuration of the members also provide for ease in placement of the assembly in a living body wherein preferably one ass...

The rate of set of an aqueous slurry of hydraulic cement can be retarded by means of an additive comprising a water-soluble polymer which contains hydroxamic acid pendant groups. Hydroxamated acrylamide polymers and copolymers are preferred additives for retarding set in cement slurries.

The invention provides compositions intended for the treatment of fibrous materials. These compositions contain at least one cationic polymer, at least one anionic polymer, at least one alkali metal salt and at least one non-ionic surface-active agent or surface-active agent which contains one or more carboxyl or carboxylate groups in addition to non-ionic groups.

An antibiotic complex designated herein as BBM-1675 complex is produced by fermentation of certain novel strains of Actinomadura verrucosospora. The complex may be separated into two major components, BBM-1675A1 and A2, and four minor components, BBM-1675 A3, A4, B1 and B2, and such components exhibit both antimicrobial activity and antitumor activity.

The present invention provides for an absorbent planar structure or so-called "sponge cloth" as well as for the method of making such a structure. The absorbent planar structure itself is permeated with pores and comprises a latex-bonded fiber material optionally reinforced with a woven or knit material, a layer of known foamed plastic, non-woven fabric or abrasive fleece. The method for making su...
