Title: Transforming cells with hepatitis virus DNA - so they express surface antigen but not core antigen or entire Dane particles
Inventor: TIOLLAIS P
IPC: C07K14/02
Filed: 1980-04-22
Abstract: Method for transforming (or determining the possibility of transformating) a cell culture, pref. eucaryotic, with DNA from hepatitis virus or its genome used a vector (esp. a plasmid) contg. an insertion sequence (IS). (IS) includes at least a part of the viral DNA coding for the immunogenic protein which induces in vivo prodn. of antibodies against the whole virus, as well as the viral promoter which normally controls transcription and translation, partic. in a host infected by the virus. Pref. (IS) consists of two entire hepatitis B virus (HBV) DNA fragments forming a 'tandem' sequence, esp. one fragment contains the S-gene sequence (coding for the polypeptide responsible for the immunological properties of HBS), and the other is long enough to include the S-gene promoter. Also new are (IS) themselves; vectors modified with them, and compsns. (A) contg. proteins with the characteristic immunogenic properties of HBs but completely free of Dane particles, HBc, all human serum components and pref. also of DNA- polymerase. Compsns. (A) are useful as vaccines and laboratory reagents. They can be prepd. in purer form than is possible by known methods.

Title: Multiple speed polyphase induction motor design - is based on predetermined couple ratios by variation of winding steps
Inventor: JOHNSON JOHN HERBERT
IPC: H02K17/14
Filed: 1980-04-30
Abstract: The design and manufacturing technique is for multiple speed polyphase induction motors. The design is based on the selection of a stator core having the required number of winding slots, selection of number of turns and winding configuration and determination of number of turns for each of the number of poles chosen. Each functioning mode is determined by the division of windings in the slots forming several polar groups made up of a given number of concentric windings. The division of windings is altered by changing the pole steps, by changing the number of turns of specific concentric coils in each group and by changing the number of core slots included in each concentric winding for each of the similar polar groups.

Title: Digester producing methane from organic waste - with crust removal system and feed and agitation pump to recycle crust
IPC: C02F3/28
Filed: 1980-06-18
Abstract: Installation for the prodn. of a combustible gas, partic. methane, by fermentation of organic waste material, employs a prepn. tank in which raw material is strongly oxygenated while being mechanically agitated. The raw material is then transferred to a digester vessel in which an aerobic fermentation produces the required gas. The installation is now equipped with a recycling system which removes crust formed on the surface of the fermenting material and recycles it back into the fermentation. The disposition of delivery pipes through which raw material enters the digester ensures that the fermenting matter is thoroughly stirred. Crust removal is pref. via a drainage funnel into which crust is swept by a jet of fluid from a diffuser nozzle. Pref. crust removal is initiated automatically by a programmed controller or/and by a transducer sensitive to excess gas pressure build-up beneath crust formation. A single pump is pref. employed to (a) drain sludge from the digester and pass it through a heating jacket on the prepn. tank; (b) feed raw material to the digester and to agitate the fermenting material; (c) recycle drained crust and provide fluid to the crust removal nozzle. An installation to produce methane etc. from organic material. The installation is simple, inexpensive and compact. Minimum attention is required for operation and maintenance.

Title: Jig for locating casting pipe on base of ladle - for rapid removal and replacement of casting pipes, esp. during continuous casting
Inventor: CAZAUX JOEL
IPC: B22D41/56
Filed: 1980-07-11
Abstract: Jig includes an arm, which can be driven longitudinally and transversely in a horizontal plane. The arm is driven longitudinally and telescopically by the piston of a jack, and this movement causes the rotation of chains which drive a chain wheel. The chain wheel is fixed onto a holder for a casting pipe, so that when the arm is extended, the pipe swivels from a horizontal position to a vertical position, so it can easily be attached to a ladle. Specifically on a tundish trolley is a vertical pivot mounting for a tubular chassis contg. a stationary jack. The piston rod of the jack is fixed by two bars to one end of a tubular arm, which can thus be driven telescopically along chassis via guide rollers.

Title: Procede de desulfuration d'un combustible contenant du soufre, au moyen d'une solution alcoolique d'un hydrogenosulfure de metal alcalin
IPC: C10G29/10
Filed: 1980-08-21
Abstract: L'invention concerne la désulfuration d'un combustible liquide. On réduit la teneur en soufre du pétrole brut distillé, ainsi que d'autres combustibles ou résidus contenant du soufre, en mettant le combustible ou les résidus en contact avec des solutions d'hydrogénosulfures alcalins dans des alcanols inférieurs, à des températures et pressions allant des valeurs ambiantes jusqu'aux température et pression du point critique de l'alcanol, pendant 1 à 20 minutes. On provoque ensuite la séparation du combustible en ajoutant de l'eau. Une séparation liquide-liquide permet de séparer le combustible désulfuré de la solution alcanolique. Le H2S formé au cours du procédé peut servir à régénérer l'hydrogénosulfure alcalin pour désulfurer une quantité additionnelle de combustible. Application : respect de la réglementation antipollution, dans le cas de combustibles d'origine pétrolière.

Title: Injection moulding device - in which injection section is moved bodily to the mould and includes facility for avoiding breaking reinforcing fibres
Inventor: MONNET BERNARD
IPC: B29C45/18
Filed: 1980-11-28
Abstract: Injection moulding device includes a mould and an injection section movable bodily to and from the mould. The injection section comprises an outer cylinder, having a valved outlet cooperable with the inlet sprue of the mould, and an inner cylinder reciprocable within the outer cylinder to define a variable volume chamber. The inner cylinder is provided with a screw to force working material through its valved end into the variable volume chamber. Means are also provided to move the inner cylinder through the chamber, after it has been filled with material, and the valved outlet of the outer cylinder has been contacted with the mould sprue passage to force the material from the chamber into the mould. During filling of the chamber there is a gap between the front ends of the screw and the inner cylinder. The movement of the injection section onto the mould only during injection reduces the heat exchange between the mould and the injection section. Also the gap between the inner cylinder and the screw prevents breakage of any fibrous reinforcement that is being used.
