In the feeding of sheet material to a machine such as a tyre building former (56) a sheet (11) is first placed on a table (10) and one edge of the sheet is aligned with a first datum line, preferably by tilting the table and supplying floatation air under the sheet. The sheet (11) is then picked up and moved transversely through a predetermined distance by a gripping device (12) to align the edge ...

A splicer includes a splicing head (1) into which the two yarn ends are introduced through an inserting slot (12) into a turbulence chamber (2). The turbulence chamber is formed from two juxtaposed frusto-conical chambers (3, 4) interconnected by a connecting slot (7). A pressure medium is tangentially introduced through an opening (8 or 9) into each chamber (4 or 3 respectively) for forming the s...

An apparatus for alternately stacking finite numbers of n positive battery plates and n+1 negative battery plates wherein a negative battery plate is provided at both the top and bottom ends of the stack. The apparatus includes a moving conveyor belt on which the positive plates are deposited having a spacing interval greater than the length of two negative plates. A negative plate is dropped onto...

The splicer head (5) of a pneumatic yarn splicer device (1) is provided on either side with pneumatic holding devices (15, 16) for holding the respective yarn ends (34', 35') of the yarns to be spliced together (34, 35), the inlet-mouths (33) of these holding devices having inserting aids for the yarn ends (34', 35') shaped as recesses (36, 37) of varying depth and of limited extent. With the help...

According to a first aspect, the present invention provides an apparatus for the evaluation of a longitudinally extending, flexible test carrier for the analytical determination of components of a body fluid. The test carrier has an insertion end to be inserted into the apparatus and a handling end. The test carrier is positioned and securely held in a measurement position in such a manner that it...

There are provided low temperature, storage stable, liquid mixtures of (1) isocyanato-containing prepolymers obtained from the reaction of linear and/or slightly branched polyols and a polyisocyanate characterized by a methylene group (CH2) bonded to two benzenoid nuclei, and (2) a non-hydroxyl-containing flow modifier which is compatible with the said prepolymer. Novel liquid mixtures thus prepar...

For heat treating products having a substantially circular cross section and being composed of mineral fibers containing a binder in solution in water, a metal container impervious to microwaves and equipped with a conveyor device includes a source of hot gas which is directed to the surface of the product. The conveyor in the form of a movable belt and a ceiling of fixed plates cooperate to roll ...

In repairing articles of natural rubber or elastomer predominantly of natural rubber with cured polymer or prepolymer (polyurethane/polyurea), adhering advantages are obtained especially at elevated temperatures when the damaged area is treated with halogen-containing oxidant dissolved in 1,2-dichloroethane instead of other solvents.

A sealing cap for mating to cylindrical parts such as the bolt guide of a spot-type disk brake. The cap includes a resilient boot one end portion of which is adapted to be secured circumferentially to a first cylindrical part and the other end portion of which is adapted to be secured circumferentially to a second cylindrical part. At least one of said end portion comprises a rigid insert member. ...

A method for providing polymer-densified fillers consists essentially of mixing 100 parts of a silicone polymer with 50 to 500 parts of reinforcing filler or 400 to 5000 parts of extending filler and mixing such blend for an amount of time effective for providing a dense, free-flowing particulate mixture.

An apparatus for atomization of high temperature melts to from very finely divided powder. The apparatus has a ceramic central melt delivery tube. Melt is introduced at the top and exits at the bottom. At the exit surface a high velocity gas impinges on the melt to atomize the melt into fine particles. The bottom portion of the melt delivery tube has an internal shape to expand the external config...

A method for generating prime powder from a material having a high melting point and apparatus for generating the powder is taught. The apparatus includes a melt delivery tube. The melt of the high melting material is introduced into the tube and exits from the tube into an atomization zone. Gas is delivered to the zone at high pressure as a stream to atomize the melt. Pursuant to the present inve...

In atomizing a body of molten material having elevated melting point by directing the molten body as a stream into an atomization zone and directing a stream of atomizing gas into said stream to atomize and disperse it, the orifice from which the gas is delivered is positioned closely proximate the surface of the stream to be atomized, e.g. less than 0.45 inches way. A large percentage of fine par...

The method of producing fine powder molten metal comprising providing a source of the molten metal to be atomized, delivering molten metal from said body to an atomization zone through a melt delivery tube, the portion of said delivery tube which is exposed to said atomization zone consisting essentially of boron nitride, directing a stream of atomizing gas against said stream in said zone to atom...
