Inventor: SVATOS ALES
IPC: A01M1/02
Filed: 2000-06-15
Abstract: Tétradéca-8,10-diénals isomériquement purs, préparation synthétique desdites substances et leur utilisation en tant qu'attractifs sexuels pour les mineuses des feuilles du genre Gracillariidae (Lepidoptera, Insecta), en particulier procédé de préparation de (E8,Z10)-tétradéca-8,10-diénal et son utilisation en tant qu'attractif sexuel pour la mineuse des feuilles du marronnier d'Inde [Cameraria ohridella Deschka et Dimic; 1985 (Lepidoptera:Gracillariidae)]. Le composé susmentionné peut être préparé par mise en réaction de (E)-9-(tert-butoxy)-1-jodnon-1-ène avec du 1-pentyne dans un solvant basique, de préférence une alkylamine, en présence d'un catalyseur Pd(0) mélangé à un sel cuivreux pour obtenir du (E)-14-(tert-butoxy)tétradéc-6-én-4-yne, à la suite de quoi l'ényne susmentionné est réduit pour fournir du (4Z,6E)-14-(tert-butoxy)tétradéca-4,6-diène. Un groupe protecteur est alors enlevé dans un environnement acide et le (8E,10Z)-tétradéca-8,10-dién-1-ol préparé est encore oxydé pour fournir le (E8,Z10)-tétradéca-8,10-diénal. Ce composé est appliqué directement, en solution ou dans un mélange en combinaison avec des composés supplémentaires, ou sous forme de ses dérivés pro-phérormone, sur un support approprié et utilisé dans divers types de pièges contenant, outre de l'attractif, une substance de retenue de teignes pour contrôler les populations de mineuses des feuilles du marronnier d'Inde, ou dans des dispositifs de piégeage en masse pour les teignes mâles ou dans des dispositifs contenant, outre l'attractif, des insecticides, un agent de contrôle biologique ou des composés destinés à réguler le développement des insectes (régulateurs de croissance des insectes), dans lesquels les mâles attirés sont tués, ou bien des agents sont pulvérisés sur les populations de mineuses des feuilles, ou bien encore le composé selon la présente invention peut être dispersé dans l'atmosphère dans des concentrations capables de désorienter les mâles et de les empêcher de copuler avec les femelles de leur espèce.

Patent WO-0118498-A1 (WO)
Inventor: LENZING THOMAS
IPC: G01F1/00
Filed: 2000-09-05
Abstract: The invention relates to a device (1) for measuring at least one parameter of a medium that flows in a conduit (3). The device is especially used for measuring the mass of a flowing medium, the intake air mass of an internal combustion engine for instance. Liquid and solid particles that are contained in the conduit (3) influence a characteristic behaviour of a measuring element (34) which serves for determining a parameter of the flowing medium. An inventive protective grid (38) rejects liquids and solid particles from the measuring element by guiding said liquids and particles to an inner wall (8) of the conduit (3). The device (1) also stabilises the flowing medium by producing longitudinal whirls in a direction of flow.

Title: Particulate foamed polyolefin prodn - by expansion with opt halogenated hydrocarbons in presence of water
IPC: C08J9/18
Filed: 1971-02-18
Abstract: Finely comminuted, partially crystalline polyolefine is heated at a temp. lower by 10-40 degrees C than the m.pt. of the polyolefin crystallites in a hydrocarbon(s) opt. halogenated having a b.pt. lower by 50-200 degrees C than the m.pt. of the polyolefine crystallites, and in the presence of water, which prevents the polyolefine particles from coalescing under a pressure equal to or higher than the vapour press. of the (halogeno) hydrocarbon at the temp. of the reaction.

Title: Regenerative gas drier - with automatic regulation and control system
Inventor: LANCIER PETER
IPC: B01D53/02
Filed: 1971-07-22
Abstract: Automatic changeover between the working and stand-by driers in a twin installation where the stand-by drier is being regenerated, is by a set of solenoid valves interconnecting the inlet sides of the drier units with the main wet gas input and the dry regenerator gas supply. The control signals for these solenoid valves are esp. derived from microswitches operated by the rise and fall of the individual drier units as their wt. decreases with reduced moisture content or increases with higher moisture content. Esp. each container is resting on a compression spring but balance systems or immersion weighers may be used. Instead of gravity sensitive signalling the solenoid valves may be regulated by signals from moisture sensors in the outlet lines from the drier elements.

Title: Intermittently cleaning dust filters - by sudden blowing back into vacuum vessel
Inventor: HOELTER HEINZ
IPC: B01D46/04
Filed: 1972-06-10
Abstract: A method of cleaning filter bags, chambers, pockets or the like, which collect dust on their inner surfaces is as follows: at intervals, each filter is isolated from the incoming dirty gas stream and is suddenly connected to a vacuum system; thus the sudden creation of a vacuum inside the filter causes clean gas to be sucked back through the filter, thus removing the dust completely from inside the filter and conducting it out via the vacuum line.
