IPC: C12P41/00
Filed: 1989-05-17
Abstract: The stereoisomerically pure esters of (2R,3S)-3-(4-hydroxy or 4-alkoxyphenyl)glycidic acid, which is a starting compound for the preparation of diltiazem, are prepared by stereospecific enzymatic hydrolysis. By using such an ester, it is possible to economically prepare the (2S,3S) isomer of diltiazem to the exclusion of other stereoisomers.

Abstract: A method of forming internal high temperature barriers in structural metals is provided. The barriers prevent movement of boundaries and dislocations inside the structural metal, and make structural metals creep-resistant at high homologous temperatures. The method comprises providing a first layer of structural metal, such as tungsten, molybdimum or rhenium, implanting ions, such as potassium, into this layer, and layering a second layer of structural metal on the ion-implanted first layer to form a laminated product. The steps of implanting and layering can be repeated an arbitrary number of times.

Abstract: A rigid inflatable boat which eliminates the hull-to-deck joint by mounting the deck part (14) to the hull part (12) of the boat by means of a box girder or inflatable bladder or the like (16) provided along the longitudinal axis of the boat. The longitudinal side edges of the deck part (14) are spaced from the longitudinal side edges of the hull part (12) of the boat. Inflatable structures or shrouds (26, 36) surrounding buoyant or inflatable structures (28, 38) are attached to the rigid deck and the hull parts. This results in a modular vessel which is readily assembled and disassembled for shipping, warehousing, nesting storage, and replacement and/or repair of one or more modules. The vessel also provides buoyancy aft in the form of an inflatable (36) or foam member (50) mounted across the transom. The aft edge (46) of the rigid hull portion of the boat is formed so as to channel the water away and thus break the water away at the back of the boat.

Abstract: The supervision messages consist of a general addressing message (MGG) followed by shared addressing messages (MGA-P). The message (MGG) contains all the information common to all the user groups and a datum for structuring the user group, and the messages (MGA-P) a shared address. The group is thus defined in a manner inherent to the supervision messages and can be reconfigured at any time.

Abstract: The precision assembly of a bridge (2), rotor (3) and stator (4), all made of metal and precision-manufactured, on a base (5) or board which is made of synthetic material or cold-formable metal and the manufacturing precision of which is markedly lower than that of the elements assembled on it, is possible by the use of a fixture (1) comprising a particular number of positioning pins (11, 12) allowing the exact positioning of the various elements relative to one another and inserted into holes (22, 40) provided for this purpose in the metal components. Studs (51, 52) forming part of the base piece and of the same material as this are themselves seated in other holes (21, 41), having some play relative to the metal components. Where studs made of synthetic material are concerned, sonotrodes sliding in the holes (13, 14) of the fixture cause the tops of these studs to melt, thus forming heads (51b, 52b) capable of holding the various components relative to one another; in a similar way, as regards studs made of cold-formable metal, the fastening of the various components to one another is carried out by crimping. <IMAGE>
