In a method and an apparatus for exchanging at least one full roving bobbin (29) on a spinning machine, the roving start is cut to such a length that it projects beyond a guide face (35), the blowing-air stream (44) having a blowing direction directed essentially in the extension of the guide face.

On a spinning frame, the roving supply to the drafting zone is held in round cans placed horizontally on a rack above the frame. The centre of the can is occupied by a large dia. spindle. The frames stand back to back with a central top rack on which the cans are laid horizontal, or slightly elevated at the front and in tiers of three, offset to that each roving descends in a vertical line which d...

The rotor of the hammer breaker is fitted with ring-shaped hammers which are located with considerable clearance on the rotor bolts. Beneath the rotor (7) is an inclined or horizontal roller track with driven or non-driven transport rollers (2), in the rear zone of which and opposite to the rotor is a driven eccentric roller (4) acting as anvil. The eccentric roller consists of a roller core with ...

A rotary cutting die assembly (10) comprised of a mandrel (12) adapted to be rotatably mounted in a rotary die cutting press, and a cylindrical cutting sleeve (14) and drive gear (16) slip fit over the mandrel (12), provide a method and apparatus for replacing the cutting edge (36, 38) of a rotary cutting die (10) at a reduced cost for materials, manufacturing and shipping than that associated wit...

PURPOSE:To manufacture the raw material alloy for rare earth magnets contg. a small amt. of impurities and having excellent magnetic characteristics by reducing oxides and halides of rare earth elements by Ca in the presence of Fe and B, and obtaining an Fe-B-R intermediate raw material alloy of specified composition. CONSTITUTION:The powder of the oxide or halide of a rare earth metal is previous...

PURPOSE:To manufacture the raw material alloy contg. a small amt. of impurities and having excellent magnetic characteristics by reducing electrolytically oxides and halides of rare earth elements in the presence of Fe and B, and obtaining an Fe-B-R intermediate raw material alloy. CONSTITUTION:In electrolyzing the oxides of rare earth elements, LiF and NdF3 (68wt% NdF3-LiF is preferable) are used...

PURPOSE:To improve contrast forming a black matrix through lamination structure of gold - black or gold - black and other material, and forming a liquid crystal panel by using a substrate where dispersion density of spacers on the black matrix is higher than that of other part containing a picture ele ment part. CONSTITUTION:After an orientation film 3 formed of polyamide is formed on a color filt...

The parts described relate to an apparatus for making a tyre reinforcement from a single cord. Each lever (2) of the apparatus carries, at its end, a groove (3) describing a partial oval. The cord may be attached thereto. A hollow (98) serves as a former for installing a bead-core.

In a filter made of a long strip of a folded filter medium, the novelty is that the folded surfaces are kept apart by spacers; that the spacer surfaces are smooth and hemispherical; that the face of the spacer in contact with the filter medium lies flush and is glued or welded to the surface; that the spacer is applied as a viscous mass in droplet form which subsequently cures and hardens to a mus...

The fault recognition system is used to identify defects in sensors, e.g. a speed sensor, providing inputs to a processor-based controller. The sensor (12) is coupled to an A/D converter (13) that provides input to the memory (11) of the microcomputer (10). For a vehicle engine control system the computer provides output to an ignition system (15) and an indicator (14). The data from the sensor is...

A mattress or cushion cover is provided in which the cover comprises a sheet material which is permeable to water- vapour but substantially impermeable to liquid water, said sheet material having a bacteriostat or bactericidal substance incorporated within the material or contained in a coating on the inner surface.

A swivellable fitting assembly has a housing with a stem with a rotatable nipple on the stem. The rotatable nipple is sealed and spaced from the nipple to enable rotation of the nipple or housing with respect to one another.

Premixes of a polyol suitable for polyurethane or polyisocyanurate foam preparation, 1,1-dichloro-1-fluoroethane and optionally additives and/or auxillary blowing agents which do not require a stabilizer to inhibit reaction between the fluorocarbon and the polyol. These mixtures are useful for polyurethane and polyisocyanurate foam preparation.

Metal castings having reduced residual carbon ash and surface flaws are produced by an evaporative pattern casting process, in which an organic foam pattern is vaporized upon contact with a molten metal leaving a metal replica of the pattern. The organic foam used in this process comprises a polymer formed by polymerizing CO2 with one or more oxirane compounds.
