Abstract: A signal representing the RPM of an internal combustion engine (18) is produced by a signal processor (10) connected to the battery (14) of the vehicle (22). The signal processor (10) derives an electrical signal from the battery (14) which contains signal components produced by operation of the vehicle ignition system (16), as well as components from a multitude of other sources (20) such as the voltage regulator, fans, air conditioning and other electrical systems of the vehicle (22). The signal processor (10) filters and signal processes the signal derived from the vehicle battery (14) to produce a signal having a frequency which is related to the RPM of the engine (18).

Abstract: 1. Hermetic seal whose purpose is to form together with a counter-ring a hermetic device between a rotating shaft and a fixed part, especially applicable to centrifugal pumps, and comprising, in a classical manner, a friction ring (1), a flexible membrane (5) comprising at one end a disc (4) which is made integral with the friction ring (1) by means of an assembly housing (6) and a collar clamped by a band on to the component which is to be made hermetic, a brace component (7) on which is set the assembly housing (6) and a return element (10) assembled between the brace component (7) and the band in order to separate the two ends of the membrane (5) from one another and, in addition, an exterior elastic bellows (11) which covers it over practically the whole of its length, the space (16) between the interior membrane (5) and the said exterior bellows (11) being partially filled with a neutral liquid or grease, characterised by the fact that the exterior elastic bellows (11) is held by clamping means (14, 15) applied at least to the end parts of the ring and forms with the interior membrane (5) a hermetic cavity in which the liquid or neutral grease can be put under pressure by elastic deformation of the said bellows, under the influence of the pressure of the fluid against which hermeticity is to be obtained and thus transmit an axial force to the friction ring (1) and maintain a friction contact which ensures dynamic hermeticity in the best conditions.

Abstract: A dehydrating screw press by which an advancing product to be deshydrated is pressed, by the rotating movement of one or more screw elements with a conical shaft (1) and a conical spiral (2) operating in a corresponding space up to the wall of a filtering cage (3). As the increasing diameter of the spiral (2) conforms to the like reduction of the shaft section (4), the use of the helical elements fitted side by side allows each spiral to operate with a profile extending up to the other helical element wall. Therefore, non-intermeshing zones are avoided during the dehydrating phase in the intermediate space. As the two pressing elements are rotated in opposite directions, rotation of the pressed material is avoided, thus advancing the product in an axial direction. The filtering cage used for a press with two helical elements shows a confirmity with two components (5 and 6) interconnected on lines (7 and 8) at the intermeshing area of the two spirals.

Abstract: Un appareil d'échange ou de mise en circulation de chaleur comprend un système de conduites (12) connectées à une entrée (13) et à une sortie (14), pour permettre la mise en circulation à travers le système d'eau ou de tout autre liquide pratiquement incompressible. Le transfert thermique s'effectue par l'intermédiaire des parois des conduites et la mise en circulation dans l'appareil est périodiquement interrompue, le transfert thermique continu qui s'effectue par l'intermédiaire des parois des conduites provoquant alors dans celles-ci la transformation par congélation du liquide en glace. Une première paire des parties (15) dudit système sont relativement isolées thermiquement ou protégées de l'air froid en écoulement, ce qui permet d'obtenir une congélation retardée de l'eau dans ces parties par rapport à la transformation par congélation du liquide en glace dans une seconde paire de parties non isolées du système situées entre les deux parties de la première paire. Ainsi la formation de glace dans la seconde paire de parties en direction de ses extrémités en communication avec la première paire de parties provoque une augmentation de la pression qui s'exerce sur le liquide non congelé dans les parties non isolées du système. On relâche alors la pression de l'eau ainsi accrue en plaçant chacune des parties de la première paire en connexion par l'intermédiaire de conduites ramifiées isolées (17, 16) avec un organe isolé et fermé de relâchement (16A) ou d'absorption de la pression, ce qui permet d'éviter toute rupture des conduites dans n'importe quelle partie du système.

Abstract: The invention provides a process for producing gamma-­lactones useful for incorporation in flavourings and fragrances, wherein a micro-organism which is acceptable for making food grade products and which does not metabolize gamma-lactones, is cultured aerobically in a culture medium containing as the substrate a hydroxy fatty acid having an even number 4 of carbon atoms between the carboxyl group and the carbon atom carrying the hydroxy group. The preferred micro-organism is a Saccharomyces cerevisiae, Debaromyces hansenii or Candida boidinii species. The gamma-hydroxy-alkanoic acid reaction product of the process is lactonized either in the fermentation broth or after separation therefrom. Especially suitable are 12-hydroxy fatty acids such as ricinoleic acid. 
     The hydroxy fatty acid may be added either pure or as the mixture obtained by hydrolysis of an ester thereof. Enzymatic hydrolysis of such ester may be done in situ in the fermentation broth.
