A bobbin magazine for mounting on an end plate of a traveling service tender comprises a band movable on an endless path, compartments on the band to receive sticks of telescoped bobbins and a transfer device to transfer sticks from the magazine to the tender. The magazine can be hinged to the tender so that the magazine can be swung out to expose the end plate.

Disclosed is a method for stopping and starting a reactor equipped with a heat exchanger, a catalyst settler, a catalyst filter and the like, which method is suitable for use in a process for the preparation of acrylamide by reacting acrylonitrile with water in the presence of a metallic copper-based catalyst used as a suspended bed. According to this method, various undesired phenomena which may ...

PURPOSE:To promote elimination or reduction of labor in assembly work, by fitting to a piston a boots piston in a condition that it is spread to be opened by air from a radial air blow port provided in a cylindrical jig. CONSTITUTION:A boots piston 10 is mounted so as to be fitted to a groove 11 along the upper surface of a circular plate-shaped part 5, and an inside end part 10a of the boots pist...

An aliphatic polyester with low water absorption is selected as a coating material for hydrophilic polymers like starch. The polyester can be degraded by bacteria or fungi. This polyester may, for example, be a polyhydroxycarbonic acid. It is dissolved and applied to the components, of starch, for instance, by one of the customary physical or chemical coating processes. Once the solvent has evapor...

The isopropyl ester derivative of ganglioside GM1 is shown to exhibit antiinflammatory and antiexudative activities, and therefore is useful in the treatment of various systemic, ophthalmic or topical pathologies, particularly those pathologies characterized by inflammatory phenomena. The derivative is also shown to be active after both oral and topical administration.

A novel paintability-enhanced light-weight joint compound comprises (1) 38-93 wt.% of a filler selected from a group composed of calcium carbonate and calcium sulfate, (2) 0.5-7 wt.% of a non-leveling agent (3), 3.5-25 wt.% of an expanded perlite with water-repellant material, (4) 0.5-1.8 wt.% of a thickener, (5) 0.5-10 wt.% of a binder, and (6) a water. The non-leveling agent is pref. attapulgus...

The invention concerns a coupled aromatic compound represented by the formula Ar - Y I wherein Ar is an aromatic moiety different from Y and Y is an aromatic moiety represented by one of the formulae: wherein A is an aliphatic ring system bonded to the aromatic ring; Q is separately at each occurrence hydrogen, alkyl or inertly substituted alkyl with proviso that the carbon atom bond...

The induction system has two banks of cylinders respectively shifted with respect to each other in the direction of the alignment of the cylinders. Intake ports are provided to face the space between the two banks and a surge tank leads intake air to each intake port. Intake passages are curvedly formed for feeding intake air from the surge tank to the cylinders of each bank and consist of upstre...

Antigens derived from ticks and their purification. Genes encoding such antigens and their cloning and expression from recombinant DNA molecules. Further, the invention describes the use of purified antigens and recombinant expression products having similar biological activity to those purified antigens to provide vaccines to protect cattle against tick infestation.

The system has a card storing the whole or a portion of a stereos copic fingerprint of an authorised person. A card reader to which the card is inserted reads the whole or a portion of a stereoscopic fingerprint of the card possessor. An assessor judges whether a card possessor is an authorised person or not based upon the result of comparison of the whole or a portion of the stereoscopic finger...

The method for eliminating the harmonics and for controlling output voltage modulates the pulse width of the switching function. A sinusoidal signal is biased so that the mininum value becomes zero for solving the constrained condition caused by pulse width modulation. A triangular wave is modulated so that one pulse is obtained at every 30 ↿ during the half period of the switching function. A ...
