Novel non-ionic contrast media are efficiently prepared from generally available ionic contrast media or non-iodinated precursors. Particularly, polyhydroxyhalo-hydrocarbons are employed with a triiodo-substituted acylamido benzoic acids in aqueous weakly basic media to selectively substitute the amido nitrogen, followed by activation of the carboxyl group for amide formation.

PURPOSE:To enable sure feed work, by using pairs of clamping claws to surely mechanically clamp the lobes of an electrode plate component in a first position in a certain process, regardless of the degree of deformation of the component, to feed it to a second position in another process. CONSTITUTION:The lobes 2 of an electrode plate component 3 in a first position D in a certain process are mech...

The invention relates to a cutting machine, in particular a circular-knife slicing machine for foodstuffs, having a housing to which a cutting tool assembly having a cutting tool acting on the product to be cut is fixed by means of a closure so as to be detachable in operation. The object on which the invention is based is to provide a cutting machine of the type described at the beginning, in whi...

PCT No. PCT/GB79/00112 Sec. 371 Date Mar. 5, 1980 Sec. 102(e) Date Mar. 4, 1980 PCT Filed Jul. 4, 1979 PCT Pub. No. WO80/00128 PCT Pub. Date Feb. 7, 1980.In a shredding machine having contra-rotating cutter shafts (16,17) carrying cutters (18), one shaft (16) is at a lower level than the other and the side of the shredding chamber (12) alongside the lower shaft has an ejection chute (71) for intra...

The invention provides an electric lead-acid storage battery of maintenanceless type, preservable charge with only the acid absorbed in the plates and separators. The battery is characterized in that the grids are made of an alloy of lead free of antimony, particularly lead-calcium-tin, and carry active material provided by pastes containing organic inhibitors, such as ligninsulphonic acids, and i...

The invention relates to a blood centrifugation cell, comprising an outer rotatable container (1) delimiting a portion of space in which a body is provided which is rigidly connected therewith and is formed by two revolution walls (2,3) connected at the ends, a stationary joint (10) being provided at the top of the container (1) and comprising two conduits (11,12) which are coaxial to the joint, t...

The invention relates to a continuous blood centrifugation cell, comprising an outer rotating container (1) which accomodates a body, rigidly connected therewith and coaxial thereto and formed by two walls (2,3) joined at the ends, the outer container (1) carrying at its top portion a stationary joint (9) comprising conduits (10,11,12) which are coaxial to the stationary joint (9), the outer condu...

Apparatus for spreading manure comprises an elongate hopper 12 mounted on a mobile frame. An axial feed rotor 18 runs along the inside of the base of the hopper and urges manure forwardly to a transfer rotor 25 which pushes the material sideways through an opening 21 to an overshot impeller 23 which throws the manure sideways from the apparatus. On the axial feed rotor 18 are blades 19 extending o...

A centrifuge bowl mount with a base and having one or more toggle members disposed thereon which are movable from a non-contact or non-engaging first positon to a contact or engaging second position in which they either (a) contact or engage the bowl or (b) move other members such as seal members disposed on the base or move push membes which in turn move the seal members to contact or engage the ...

A process and apparatus is provided for the production of nitrogen with over-atmospheric pressure by two-stage rectification of air at low temperatures. Air (1) is compressed (2), pre-purified (4, 6), cooled (33) in heat exchange with products of fractionation, and fed to the rectification device. An oxygen-enriched liquid (19) from the sump of the low-pressure stage (13) is vaporized (15) in cont...

The transmission device comprises first (I) and second (II) groups of input and output gears arranged on either side of a set of input (22, 28, 34, 46, 56,40) and output (24, 32, 36, 48, 54, 42) gears which produce a given speed ratio. The presence of first and second clutches (18, 20) enables both sequential as well as non-sequential gear shifting between the groups of gears and/or the gear locat...

A pleated media filter element is disclosed which includes pleat spacers which are an integral structural part of the pleated media. The construction of the pleat spacers is accomplished by scoring on the unfolded media a continuous line pattern upon the portion of the media which, when folded, forms a pleat tip of the element. When the scored media is folded into pleats the patterns each define a...

Foams having aspartase-producing microorganisms bound to the foam are made from polyurethane prepolymers which are capped with polyisocyanates, including diisocyanates, derived from methylene-bis (phenyl isocyanate) which is commonly known as MDI. These MDI based foams are hydrolysis resistant as compared to the previously used TDI based foams. The foams can be used to produce L-aspartic acid unde...
