69727-18 In an apparatus for pulling a thread, band, or the like, off a thread spool, the thread or the like can be pulled off from above the thread spool. To ensure that the thread is pulled off, for all practical purposes, with no twisting, the thread can be pulled off the thread spool over each of the two opposing end faces of the thread spool in alternation.

The present invention relates to the coproduction of a combustible feed gas stream useable as an energy source and a sulfur-containing second gas stream useable as a feedstock for the production of sulfuric acid. The process includes heating coal in the presence of an oxygen-lean atmosphere under partial coal gasifying conditions to produce a solid carbonaceous char and a crude coal-gas stream. Su...

The present invention relates to a process and a device for polymerizing alpha-olefins such as ethylene or propylene in a gas phase. The device comprises a gas phase polymerization reactor (5) into which a suspension of prepolymer particles in liquid saturated hydrocarbon(s) is continuously introduced. The prepolymer suspension is prepared in one or more prepolymerization vessels (14) and is conti...

The influence of drill string magnetization on an azimuth measurement in a borehole by means of a magnetometer package included in a drill string having a longitudinal axis is eliminated by first eliminating the influence of the cross-axial components of the drill string magnetization through magnetometer readings at various angular orientations of the drill string, and then eliminating the influe...

The invention relates to the determination of the torque Ts acting at the surface in a drillstring while drilling a borehole, the drillstring being rotated by rotating driving elements which include an electrical motor with an output shaft. The method comprises the steps of: measuring the angular acceleration gamma of said shaft; measuring the torque Tm of said motor; determining the gear ratio ...

The conventional processing of rubbers into shaped articles of manufacture normally include a compounding step. In this compounding step the rubber is mixed with fillers, curatives, and various other additives so as to obtain a homogeneous mixture. The relatively high viscosity of these raw materials makes it necessary to utilize heavy machinery, such as Banbury mixtures, which consume large amoun...

This invention provides an erasable optical disk, on which information is recorded and reproduced repeatedly through the irradiation of laser beams, and an optical information recording/reproduction apparatus which records and reproduces information on the erasable optical disk. In erasing and then recording information on the erasable optical disk by using an erasing laser beam and a recording/re...

An improved grid plate flow distributor assembly for use in a pressurized catalytic reactor in which gas and liquid materials flow uniformly upwardly through the grid into the reactor ebullated catalyst bed. The grid plate assembly contains multiple vertical flow tubes each covered at its upper end by a cap which is spaced outwardly from the tube upper end and preferably has tapered sides. The cap...

PURPOSE:To form a wiring pattern whose superconducting transition temperature is high, by baking a ceramics based superconducting paste wiring pattern in the state that said wiring pattern is coated with a heat resistant cover. CONSTITUTION:After a wiring pattern 3 is screen-printed on a substrate 2 by using ceramics based superconducting paste, the wiring pattern 3 is coated with a cover composed...

PURPOSE:To easily mass-produce the circuit board irrespective of the number of interconnections by using a mask for electrode formation whose opening part for electrode formation has a prescribed shape. CONSTITUTION:The surface of a metal 3 of a substrate 1 is covered with a resist 4 for circuit pattern formation; metal parts corresponding to circuit patterns are plated; the resist is removed; par...

PURPOSE:To opaque an object very much by using a short-sized image forming means by repeating a process of opaquing an area which is less in width than an object area plural times to the overall width of the object place. CONSTITUTION:An indication based upon position information is sent to the thermal head 32 of a thermal printer 31 as a light shielding method (opaquing) for a plate making film, ...

There are disclosed flame-retardant, high-temperature resistant polyimide foams having the general formula ,(I) The foams have an elevated thermostability and, determined in a thermogravimetric analysis at a heating rate of 20 degrees per minute, have a maximum weight loss between 550 and 650.degree.C. The overall weight loss up to a heating temperature of 350.degree.C amounts to less than 3 % by ...

In an arrangement of a differential for driving two vehicle wheels, with an outer casing and a gearbox casing supported by a bearing. Provided on the gearbox casing is an annular face which is concentric in relation to the bearing axis and with which a solid of revolution made of an elastomer material and held on the outer casing is in continuous, concomitantly rotating contact with a small contac...

A three-dimensional braid structure comprising a plurality of interlocked layers is created by causing a plurality of package carriers (15) of yarn (16) to move along a plurality of serpentine paths (6) defined by track modules. The track modules extend generally in one direction to define a longitudinally extending path corresponding to a first layer of the braid structure and in another directio...
