Methanol is made in a liquid-phase methanol reactor by entraining a methanol-forming catalyst in an inert liquid and contacting said entrained catalyst with a synthesis gas comprising hydrogen and carbon monoxide.

This invention concerns improvements to procedures to splice yarns (20-21), whether textile yarns or otherwise, the splice being obtained by coupling two single untwisted yarns (20-21) and by reconstituting the twists thereafter, by which improvements a part of the single yarns (20-21) is untwisted until twists of a sign opposite to the sign of the original twists have been imparted, such part the...

This invention concerns an improved splicer (10) to splice textile yarns mechanically, the splice being obtained by coupling two single untwisted yarns (70-71) and reapplying the twists thereafter, part of such single yarns (70-71) being untwisted until twists of a sign opposite to the original twists have been imparted, such part then being doubled and remaining tails (270-271) being obtained, th...

An automatic tractor guidance system for controlling the steering of a tractor to follow a previously plowed furrow is disclosed. A furrow follower is provided with a sensor for sensing the direction of the path relative to the direction of travel of the tractor. The steering direction of the tractor is likewise sensed. The two sensor signals are combined and compared to a convergence frequency si...

1. Process for manufacturing carbon-enriched solids resistant to biological attack, from waste which contains organic carbon compounds as starting material, especially from town waste containing cellulose or cellulose-like compounds, in which the starting material undergoes a pyrolitic treatment by flame-free blowing with oxygen free heating gas so that it de-gasses, air being excluded, characteri...

Polyol is recovered from polyurethane based polyurethane foam by a process which includes first dissolving the foam in a saturated alcohol, preferably diethylene glycol, having a boiling point between about 225 DEG C. and 280 DEG C. at a temperature between about 185 DEG C. and 220 DEG C. under a non-oxidizing atmosphere. The solution is reacted with water in the presence of an alkali hydroxid...

A polyester film especially suitable for use as the base film for magnetic recording media provided with excellent slipperiness, flatness, slidability and durability can be manufactured by endowing a polyester film with surface conditions represented by a formula Ra >/= 2 x 10<-4>.H2 + 0.008, wherein Ra is the average roughness ( mu m) and H2 is the number of the secondary interference fringes mea...

A device is provided for sensing the condition of a pneumatic tire preferably of the type used on an automobile wherein the tire is mounted on a tire rim and the tire is subject to normal vibrations. The device comprises a housing, a band for mounting the housing to the tire rim, a sensor for monitoring the condition within the tire, circuitry operatively connected to the sensor for generating rad...

This invention relates to a body of three-dimensional fabric, a method of producing such bodies or parts of various shapes from three-dimensional fabric and also relates to apparatus for industrial performance of this method.

A strong, durable nonwoven fabric comprising polyester and/or polyolefin fibers arranged in a pattern of high density, lightly entangled fiber regions is produced by fluid jet entanglement followed by application of binder to discrete areas of the fabric or to the whole fabric.

A disc brake for installation on heavy automotive vehicles, comprises at least two rotating discs fixed to each other and spaced apart axially and rigidly fixed on the brake rotor, and a stirrup fixed on the brake stator. The stirrup comprises two external portions between which the discs are disposed, and at least one intermediate portion between the discs. The stirrup portions have pairs of oppo...
