A molding method of a tire involves coating the surface of a drum bladder, a turn-up bladder or an expand drum cover attached to the tire forming machine with an organic halo compd. contg. -C(O)-N(X)- [X=halogen to prevent the adhesion of an unvulcanized rubber for tires with the vulcanized bladder rubber. The organic halo compd. is pref. halosuccinimide, halo-isocyanuric acid or halo-hydrantoin...

A process for extruding films of vinylidene fluoride polymers, having a predominantly piezoelectric structure, comprises stretching an extruded film of a molten polymer at least 200% in the extrusion direction, and then cooling the stretched film to below 50≰C, while it has travelled at most 300mm after leaving the die. The films have an excellent tear strength.

The invention relates to a device for skinning double fish fillets having a skin which is highly sensitive as a result of pickling treatment, for example spiced herring fillets. Starting from a skinning machine having an entraining roller (1) which is grooved along its generating lines, a skinning knife (3), the blade (4) of which is directly opposite to the generated surface (5) of the entraining...

Compounds of formula (I) and salts thereof, wherein R is a C1-4 alkyl group, R<1> is a methyl, ethyl or isopropyl group; and OR<2> is a hydroxyl or substituted hydroxyl group having up to 25 carbon atoms. These compounds may be used for controlling insect, acarine, nematode or other pests.

A process is described for preparing a compound (I) (wherein R<1> represents a methyl, ethyl or isopropyl group and OR<2> represents a hydroxy, methoxy or acetyloxy group) which comprises reducing a compound (II) (wherein R<1> is as defined above, R<3> is a hydrogen atom, a methyl group or a protecting group and Hal represents a halogen atom. The intermediates (II) are new compounds.

Compounds having the formula wherein the broken line at the 22-23 position represents an optional double bond and wherein r1 is h or oh and the double bond is absent, or, the double bond is present and r1 is absent, r2 is an alpha-branched c3-c8 alkyl, al

A process for producing a filter element having a hollow body composed of thermoplastic synthetic fibers and having each of its end surfaces sealed, which process comprises placing on a hot plate (5), provided with a layer of a thermally conductive and releasing surface material (6), in succession, a thermoplastic sheet (7) and a filter element (4) so that an end surface of the filter element cont...

The present invention relates to methods which utilize anti-idiotypic antibodies, or fragments thereof, for tumor immunotherapy or immunoprophylaxis. Monoclonal anti-idiotypic antibodies which recognize an idiotype present on a second antibody or on a T lymphocyte or on an immune suppressor factor which is directed against a defined tumor antigen, can be used for immunization against a tumor, for ...

A tire casing is retreated by placing an assembly of a tire, a precured rubber tread and a rubber-base material between the tire and tread with a flexible airtight cover, and pressurizing a vessel in which the assembly is located to press the cover against the assembly. A pressure fluid from the vessel is fed through a check valve to the cover manifold outside the vessel which then supplies the c...

An overhead conveyer comprising an endless draw member travelling along a closed stretch and containing regularly spaced claws (2) in which a carrier hook such as a coat-hanger (3) can be suspended, each claw being capable of closing and opening for carrying or dropping a hook. The conveyer is further provided with throw-off stations, positioned along its stretch, a number of stations comprising a...

Stable, clear, antimicrobially effective, ophthalmic formulations include an ophthalmologically effective amount of a drug, especially a -COOH group-containing drug or a NSAID, and a preservative system formed of a quaternary ammonium preservative and a nonionic surfactant, all in an aqueous vehicle. These formulations are useful for treating diseases that are either caused by, associated with or ...

The mixt. pref. includes a sodium salt of an acid, a neutral and a basic amino acid. The soln. has a pH of about 11. Pref. the sodium salts are of glutamine acid, leucin and lysin. Pref. the organic nitrogen-contg. compounds are applied as a common stream, to a stream of sodium hypochlorite solution, to mix as rear as possible to the carries infection.

The pipe connections (9) for the box are formed as separate components, and each has a slightly conical, circular inner wall against which the plastic pipe (11) used in the installation is pressed inwards. Each connection also has a circular track (12). In order to fit a connection into the box, a hole is made in the wall of the latter so that the ring-shaped track of the connection can be fixed a...

Here described is a fish ladder, namely a salmon ladder with a number of top-open basins, which together form a step-like configuration. With uniform pressure distribution in mind the basins are of equal size and each basin has at its top and at its bottom respectively at least one inlet and one outlet for water.

The system is characterized by its exhaust pipes having the same length. The engine (3) has a crankshaft (8) between front row of cylinders (4) and rear row of cylinders (5). The first exhaust pipe (6) is connected to the front row and the second exhaust pipe (7) is connected to the rear row. The two pipes are joined at the back of the engine. An auxiliary catalyst (17) is disposed in the firs...
