In vibratory bulking or crimping of textile strands, the twist-stopping tendency of a vibratory crimping head is overcome by false-twisting in the vicinity of the locus of vibration and thereby, in effect, forwarding twist therethrough. The crimping step conveniently is preceded by a step of drawing the strands to increased length.

While being fed into a laterally confining region to be retained temporarily and compressively crimped therein, laterally spaced textile strands are traversed laterally to and fro along the entrance to the region. The resulting uneven cross-sectional distribution of crimped strand accumulation in the region is conducive to separation of individual strands upon exiting from the region.

Soluble phosphates are removed from a sewage effluent by controlled additions of sodium aluminate, NaAlD.sub.2, and a flocculant introduced into the sewage effluent at some point after secondary (aeration) treatment and prior to discharging the effluent to a receiving body of water, thereby reducing considerably the amount of phosphates responsible for proliferation of primitive aquatic plant life deemed ecologically inimical.

A treatment device is adapted to be supported from a supporting surface, such as a rim of a toilet bowl or other object to be treated, and includes a hook-shaped arm which clips onto the top edge of the toilet bowl rim and which has a base portion secured to the upper end of an elongated member extending downwardly through a central opening in a block of material composed of deodorizing, antiseptic, insecticide or other material and which is disposed within the toilet bowl when the arm is clippe...

A method of treating clay which is to be dewatered and disintegrated, particularly for use in rubber compounds and as an anticaking agent in fertilizers, in which an organic coating substance is added to the clay before dewatering or, if the substance is of a kind which might decompose at the dewatering temperature, after dewatering, and the mixture of clay and the substance is reduced to a fine powder.

This invention relates to new tricyclic carboxylic acid and ester derivatives and processes for their preparation. These compounds have anti-inflammatory, anti-pyretic and analgesic activity. Also included are claims for methods of treating inflammation using the carboxylic acid compounds of this invention.

Footwear treatment system comprising a conveyor made up of a plurality of chain sections each to carry a batch of footwear to be treated. Chain passes through modular footwear treatment zones in which the footwear is first heat set and then dried by vacuum. Timed meter steps conveyed to transfer batches from zone to zone at equal intervals.

Apparatus for high-speed heat treatment of web stock, particularly coated metallic stock as supplied from a coil, moved in catenary configuration through the heat-treatment apparatus. The apparatus employs a plurality of high-velocity, combustion burner assemblies specially arranged in a plurality of heating zones through which the strip is moved. A plurality of heating sections using these burners usually includes a high-velocity section and a dynamic flow section. Frequently included is a flas...

Yarn relax process wherein a yarn is tensioned and forwarded by means of an unheated fluid device to a hot zone wherein tension falls.

Removal of organic sulphur compounds, carbon disulphide and carbon oxysulfide, from inorganic gases, such as air, or exhaust gases, polluted therewith, is effected by contacting a mixture of steam and the gases to be treated with a catalyst comprising uranium oxide, and, preferably a carrier such as alumina.
