Abstract: A process and apparatus for fracturing, into a bearing cap and a connecting rod, an integral preform which defines a cylindrical aperture and two spaced-apart bolt seat shoulders. A guide member defines a first guideway along which moves a first slide member, the latter in turn defining a second guideway parallel to the first, along which a second slide member moves. A split mandrel has an upper part fixed with respect to the first slide member and a lower part fixed with respect to the guide member. The split mandrel halves define an internal taperedpassageway for receiving a wedge capable of forcing the mandrel halves apart. Projections on the second slide member contact the bolt seat shoulders when the cylindrical aperture of the preform receives the split mandrel, and means are provide for urging the second slide member toward the mandrel. When the wedge member enters the tapered passageway, forcing the mandrel parts apart and fracturing the preform, the bearing cap's contact with the projections and the upper part of the split mandrel securely holds the bearing cap in place. Furtherpositional security is provided by static and dynamic locators which have a lateral pinching action on the bearing cap and on the connecting rod.

Abstract: Novel ether lipids were obtained from methanogenic (Methanospirillum hungatei, Methanococcus jannaschii, Methanococcus voltae.      Methanosarcina mazei, and Methanobrevibacter smithii), and extremely halophilic (Halobacterium cutirubrum) representatives of the archaeobacteria.    Several of the ether lipids produced by Methanospirillum and Methanosarcina genera were purified and characterized structurally for the first time.    Unilamellar liposomes were prepared from emulsions of the total polar-ether lipid extracts of such bacteria by pressure extrusion through membranes of various pore sizes. Liposome populations were shown by dynamic light scattering and electron microscopy to range in size depending on the pore size of the filter, on the source of the lipids, and on the composition of the suspending buffer medium. In all cases the size ranges indicated highly homogeneous preparations. Leakage of entrapped fluorescent or radioactive compounds established that the ether liposomes were stable to attack by phospholipase A2 and B, and were stable for at least 60 days to storage in an atmosphere of air. The detergent dialysis method of forming liposomes also produced unilamellar liposomes from most of the archaeobacterial total polar lipid extracts which were tested.

Abstract: The problems caused by chemical and thermal shrinkage of hard roll covers, are reduced by the inclusion of one or more intermediate compressive layers between the metal roll substrate and the outer cover, or topstock.   A compressive layer has the properties of being rigid enough to allow the cover to be applied to the roll, and compressible enough to deform and absorb the stresses which occur as the cover is shrinking during processing.    In  one  embodiment,  the  intermediate  compressive  layer comprises a three dimensional fabric that is  filled preferably with a thermoset resin system which cures at lower temperature than cover.   In a second embodiment,  the precise amount of shrinkage in the roll is predetermined to a high enough degree of accuracy so that a depth for the fabric layer can be used to compensate for the amount of shrinkage, thereby eliminating the need for filling.  In a third embodiment, the compressive layer is comprised of a meltable material wherein said material melts at cure temperatures. The resulting cavity is then filled with a thermoset resin.  The resulting cavity is then filled with a thermoset resin.    The problems caused by chemical and thermal shrinkage are further reduced through a method based on applying a polymeric cover layer over one or more intermediate compressive layers, curing at an elevated temperature, and, allowing the cover to shrink during curing or hardening.

Abstract: Cette invention concerne un nouveau système de communication des données permettant la transmission de données sur des lignes téléphoniques existantes et à une vitesse plus élevée qu'il n'est possible de le faire par les moyens actuels, y compris les modems traditionnels. Avec l'emploi d'une nouvelle configuration asymétrique sur les deux postes en communication, il n'est plus possbile d'appliquer les limites théoriques maximales et généralement reconnues de débit de données. L'un des poste est directement connecté à un réseau téléphonique numérique alors que l'autre poste utilise une connexion téléphonique classique. Ce système permet de limiter le problème de transmission à la compensation d'une seule interface de ligne téléphonique et d'une seule ligne analogique d'abonné. Cette invention concerne également des procédés pour assurer ladite compensation ainsi que la synchronisation des horloges, ce qui permet une installation pratique de ce système. Ce nouveau système permet d'obtenir des vitesses de transmission allant jusqu'à 64.000 bits par seconde, et possède de nombreuses applications dans plusieurs autres domaines en plein essor, tels que la transmission audio à bande large, les transmissions vidéo, les communications en réseau, la transmission de fac-similés et l'accès aux ordinateurs distants.
