Abstract: ABSTRACT OF THE DISCLOSURE:         The object of the present invention is a novel and simple process for the production of 1,2-diacyl-an-glycer-ols, wherein the acyl groups may be the same or different According to the invention D-mannitol is reacted with benzene boronic acid or a derivative thereof to form a D-mannitol-monobenzeneboronate which compound is acylated either to form, after removal of the benzeneboronate protective group, a 1,2,5,6-tetraacyl-D-mannitol with four identical acyl groups, or is acylated selectively in two stages, by first acylating the 1,6-hydroxy groups of the boronate protected D-mannitol to form, after removal of the boronate protection, a 1,6-diacyl-D-mannitol, which then is repeatedly reacted with a benzene boronic acid or a derivative thereof and then acylated in the 2- and 5- positions.  After removal of the boronate protective group, the tetra-acylated D-mannitol obtained either in the one-stage or two-stage process is split by oxidation to form a 1,2-diacyl-glyceraldehyde which in turn is reduced to the corresponding 1,2-diacyl-sn-glycerol.  By means of the invention it is thus possible to prepare 1,2-diacyl-sn-glycerols in which the acyl groups can be the same or dif-ferent.

Abstract: D-5,091 SWASH PLATE COMPRESSOR     ABSTRACT of the Disclosure A swash plate compressor of light weigh-t construction having a cylinder block defining weight reducing tubular cylinder bore portions which form, with its outer shell, a low pressure gas upper inlet channel and a pair of low pressure gas lower exit channels.  aperture means are provided in one of the heads and its associated valve plate to allow direct axial flow communication from the compressor suction inlet to the upper inlet channel for receiving a mixture of low pressure gas and oil.  Aperture means are formed in the compressor heads and their associated valve plates providing communication from the upper inlet channel to the compressor low pressure gas suction chambers via a weight reducing swash plate space that completely exposed the swash plate and each of the lower exit channels.  The result is that compressor weight is reduced while lubrication is achieved by the low pressure gas and oil mixture entering the upper inlet channel and flowing in heat exchange relation with the upper tubular portions separating a portion of the oil from gas for deposit on the upper tubular portions for subsequent gravita-tional flow to the operation portions of the compressor and with the low pressure gas and oil mixture directly exposed to and enveloping the swash plate to ensure that sufficient entrained oil is caused to separate out as a film on the swash plate sides.

Abstract: ABSTRACT OF THE DISCLOSURE:           A device for aligning fish to be handled in fish-processing machines is shown.  The object of the invention is to lead fish, especially those with approximately circu-lar cross-section to the processing tools so exactly that the processing can be carried out most economically, i.e. with a high yield without any danger of undersirable parts, e.g. the skeleton, remaining in the product to be used.  The device according to the invention handles fish whose abdominal cavity is opened.  The device comprises, in a known manner, a saddlelike guide element which supports the fish in its abdominal cavity, conveying means which engage the flanks of the fish being arranged on both sides of the guide element. A support surface which is formed with a concave cross-section carries knives extending into the fish path and lying flush with the support edges.  These knives serve to provide slots at the end of the abdominal cavity to reach into the tail part so that an aligned guiding in particular of this part of the fish becomes possible.
