A hammer adapted to be pivotally mounted between a pair of rotors in a hammer mill has a pair of sidewalls each of which is adjacent a rotor. Each sidewall has a recess which collects small pieces of scrap which get trapped between the sidewall and the adjacent rotor. A portion of the recess extends beyond the outer periphery of the adjacent rotor so that scrap collected in the recess can be eject...

1450531 Herbicidal compositions IMPERIAL CHEMICAL INDUSTRIES Ltd 15 Oct 1973 [27 Oct 1972] 49585/72 Heading A5E Herbicidal compositions comprise an aqueous solution of a salt of a herbicidal bipyridylium diquaternary cation and (A) a cationic additive to increase the herbicidal effect of the bipyridylium salt, which additive is either (a) one or more quaternary ammonium salts of formula:- wherein ...

An apparatus for making the pressure exerted by a machine-tool carriage on its slide uniform. Cams which load springs are used to apply pressure to the carriage in those regions subject to less pressure depending upon the position of the carriage. Distortion of the tool carriage slide surface and resulting inaccuracies in the machine operation are thus reduced.

PURPOSE:To prevent a normal operation from being disturbed even if kneaded matters stick to a rotation-limiting mechanism, by incorporating a scraper- arm rotation-limiting mechanism, which scrapes the stuck kneaded-matters from the bottom and side wall of a mixer, into a housing. CONSTITUTION:A shaft 3 is supported rotatably by bearings 4, 5 at both ends of a housing to be attached to a rotary ar...

PURPOSE:To assure human sense in assembly process by handling car seats etc., by controlling analogically the whole device by handle operation in synchronization with the continuous working line, and thereby making possible the continuous action. CONSTITUTION:This is composed of a plane transfer mechanism 25 provided with a longitudinal rail 1 stretching parallelly with the products transport line...

The invention relates to substitution derivatives of trisaccharide 3-fucosyl-N-acetyl lactosamine and to the immunological applications of these derivatives and of the trisaccharide itself particularly as diagnostic reagent and in therapy.

A process for producing olefines by using a fluidized bed of coke particles provided in each of a reactor and a heater, circulating coke particles through the reactor and the heater, heating the coke particles by a combustion of fuel and if desired, a part of the coke particles in the heater, thermally cracking a heavy oil with a heated coke particles as a heat carrier in the reactor, the improvem...

Hydrocarbon oils, particularly oils which have a high boiling temperature, are treated to remove organic sulphur compounds by subjecting a mixture of a hydrogenating gas, e.g. a gas containing at least 90% v/v hydrogen and is substantially free from carbon oxides, and partially vaporized oil to a hydrogenation reaction over a known hydrogenation catalyst and thereafter passing the resulting liquid...

A process for the preparation of an aromatic hydrocarbon mixture, in which a mixture of carbon monoxide and hydrogen with an H2/CO molar ratio between 0.25 and 0.75 is contacted with a mixture of two catalysts of which one (A) is capable of catalysing the conversion of an H2/CO mixture into acyclic oxygen-containing hydrocarbons and the outer (B) is a crystalline silicate, (A) contains zinc and ch...

PURPOSE:To perform photography in every direction, by providing a trestle which runs freely along rails, a support supported rotatably on the trestle, and a forked arm supported rotatably on the support. CONSTITUTION:On guide rails 29a and 29b, a running frame 31 is arranged through running roller 30 at side parts in such a way that it moves forth and back freely. A prop trestle 32 is fitted to th...

An engine carburetor automatic choke includes a heater to warm the choke bimetallic coiled spring to effect choke come-off faster than by the normal warm-up of the spring in response to ambient temperature rise, the heater being activated upon operation of a bimetallic switch upon the attainment of a predetermined temperature level, the switch also controlling energization of an electrical control...

PURPOSE:To obtain dies which form nozzles of high accuracy with high mass productivity and at a low cost by obtaining an electrocast bottom mold by the use of a circular columnar body wherein one end of a wire is fitted and inserted into the micro-hole at the center on one end face as a master mold, and forming an electrocast top mold thereon. CONSTITUTION:A circular columnar body 40 made of metal...
