Title: Method and apparatus for combining a tensioned elastic garter with a substrate
Inventor: KOCK RONALD WAYNE
IPC: A41F1/08
Filed: 1994-10-06
Abstract: A method and apparatus for forming a tensioned garter and bondingit to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surface. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.

Abstract: Rcd expression from an extra-chromosomal vector in bacterial cells in broth culture induces quiescence. Expression continues from extra-chromosomal vectors within the cells during quiescence, while chromosomal expression is suppressed. The cells may be used as factories for the production of large amounts of polypeptides of interest, particularly polypeptides which normally have an adverse effect on cell viability or growth. Expression from an extra-chromosomal vector of interest may be monitored, in view of the reduced background expression from the chromosome. Vector copy number may be amplified. Cell cycles may be synchronised. Suitable cells for rcd-induced quiescence include hns- strains of bacteria such as E. coli.

Inventor: BOYLE FREDERICK P
IPC: F16N39/00
Filed: 1999-01-11
Abstract: A system for measuring the quality and level of lubricant in an engine lubricant reservoir includes valve means for selectively directing a portion of lubricant from the engine through a first conduit for return to the engine or through a second conduit for removal from the engine. Within the first conduit are one or more sensors for sensing the condition of the lubricant passing through the first conduit. The sensors are monitored by a controller which is operative selectively to cause the valve means to block the flow of lubricant through the first conduit and direct a portion of the lubricant through the second conduit based on the monitored conditions of the lubricant. Also, the controller directs a supply of fresh lubricant to the engine in response to the lubricant in the engine lubricant reservoir dropping below a predetermined level. The lubricant flowing through the second conduit may either be stored in a lubricant reservoir and if desired subsequently intermittently mixed with the fuel in the fuel tank, or caused to flow directly to the fuel tank on command of the valve means by the controller which limits the amount of lubricant that can be added to the fuel tank so as not to exceed a predetermined lubricant/fuel ratio for the engine.

Title: Desaturase antigen of mycobacterium tuberculosis
Inventor: JACKSON MARY
IPC: C12N1/21
Filed: 1997-07-25
Abstract: The use of genetic methodology based on the fusion of the proteins with the alcaline phosphatase (Lim et al., 1995) has allowed the isolation of a new exported protein of M. tuberculosis. In the present article, first of all the isolation of a gene encoding this exported protein called DES is described as well as its characterization and its distribution among the different mycobacterial species. It is notably shown that the protein has in its primary sequence amino acids only found at the level of active sites of enzymes of class II diiron-oxo proteins family. Among the proteins of this family, DES  protein of M. tuberculosis does not present significative homologies with stearoyl ACP desaturases. Secondly, the antigenic feature of this protein has been studied. For this, DES protein of M. tuberculosis has been overexpressed in E. coli under recombinant and purified protein form from this bacterium.  The reactivity of tuberculous patients sera infected by M. tuberculosis or M.  bovis against DES protein in Western blot experimentations has been tested.  100 % of the tested patients did recognize the protein. The intensity of the antibody response against DES protein measured by ELISA of tuberculous patients sera compared with the one relating to sera patients suffering from other pathologies show that there is a significative difference between the intensity of the antibody responses of these two categories of patients.  Accordingly, DES protein is a potentially interesting tool for the tuberculosis serodiagnostic.
