The novel antigenic linear peptides of this invention comprise peptides of from 4 to 13 amino acids, which are characterized by containing the sequence valine-leucine-aspartic acid-methionine. These compounds correspond with the amino acids 231 to 243, or segments thereof including sequence 239-242 of mouse LDH-C4. The coupounds have utility in vaccines for reducing the fertility of female mammals...

An apparatus and a method for carrying out the dehydration reaction to produce a high boiling compound comprises charging a raw material and an organic solvent into a circulating system including a reactor, a preheater and an evaporator to cause the chemical dehydration reaction, drawing water, formed as a result of the dehydration reaction, together with the solvent in the form of vapor, compress...

To bond especially a mineral fibre mat (7) which does not contain a bonding agent, bonding points are produced by fixing the fibres (3) in their respective positions in the bonding area by welding or adhering them together. Welding can be effected using laser beams, hot air streams or flame jets. In the case of adhering, bonding points are produced in the form of pins (6) by injecting a fluent, so...

Chemical compounds of the formula: in which R<1>, X, Y and Z have various specified values. The compounds are useful in the preparation of agricultural acrylic acid derivatives described in EP-A-178826.

High density para-aramid papers comprising 5 to 25 percent, by weight, binder and an amount of para-aramid fibers selected from the group consisting of para-aramid pulp, para-aramid floc and mixtures thereof, compacted to provide a volume percent para-aramid fiber of at least 53 minus 0.13 times the volume percent floc in the paper are useful in the preparation of circuit board substrates having a...

Compounds of formula and stereoisomers thereof, wherein X is an oxygen or a sulphur atom; R<1>, R<2> and R<3>, which may be the same or different, are hydrogen atoms or alkyl, cycloalkyl, optionally substituted alkenyl, optionally substituted aryl, optionally substituted alkynyl, haloalkyl, optionally substituted aralkyl, or cycloalkylalkyl groups; and R<4> can be any of the groups as def...

The present invention relates to a device for producing bone cement for fixing protheses, whereby the bone cement is produced by mixing various substances with each other in a space (22) of a feed device (20) to provide a setting mass which in set condition is adapted to fix protheses at surrounding bone tissue and whereby the mixture (19) is pressed out from the space (22) by means of the feed de...

The plant comprises a cyclone cleaner incorporating two cleaning chambers sepd. by an intermediate wall in which is a pipe formation for further transport of polluted pulp suspension coming from the first cleaning chamber, in which heavy pollutants have been removed through an outlet. - Light pollutants are partially removed through an outlet to the second cleaning chamber in which, by means of th...

This invention is a fastening device (4) for securing a cylindrical object in a ruler (1) or other measuring instrument. The fastening device (4) of the invention is inset in the ruler (1) and has an oval cross section with its largest width in the longitudinal direction of the ruler (1). This results in the least amount of possible ruler weakening and the greatest possible contact surface between...

A perforated drum (1) is provided, being supported by an external support roller (2). When water has been removed from the material, it emerges through the holes in the drum. - To remove material from the surfaces of the drum and the support roller, water jets are used. The jets emanate from a perforated pipe in the space between the drum and roller.

A release body (3) cooperates with an activator (4) which can be triggered by an object at a distance from the device, causing a motivator (5) to bring the release body to its discharge position. The activator functions with a lever effect, so that a part of it cooperates with a part of the release device (1) acting as counter pressure part, to produce the freeing of the release body.
