摘要:
A fastening device for holding elements such as snap pins or clamps on a cover plate made of molded fiber which includes a holding plate spaced above the cover plate and having support plates fixed to opposite ends thereof by side walls. A separate intermediate plate is between the holding plate and support plates and the cover plate and has a plurality of claws adapted to penetrate the fiber plate. The intermediate plate and the holding plate are fastened together by hooks and/or snap fasteners.

A tube mill operated under superpressure in the milling chamber is sealed by means of blocking air, which is made available in a blocking air chamber (9) arranged on the stationary part of the journal (2) of the tube mill. A blocking air channel is provided between the stationary and the rotating part of the tube mill and joins the blocking air chamber (9) to the milling chamber. The blocking air channel contains an inclined extending section (19), which is arranged at an acute angle to the longitudinal axis of the tube mill.

A fastening plate for securing door-panel snap pins to an automobile's body to fix the interior panel to the automobile door. The fastening plate includes an aperture for slideably receiving a snap pin and a resilient rest plate positioned under the aperture for pressing the head of the snap pin against the portion of the holding plate surrounding the aperture. The resultant fastening plate securedly holds the snap pin perpendicular while permitting the radial movement of the snap pin within the clearance between the neck of the snap pin and the aperture.

A process for the production of bis-[O-(1-alkylthioethylimino)-N-methylcarbamyl]-N,N-sulfides of the formula I ##STR1## wherein R is a straight-chain or branched alkyl group of 1 to 5 carbon atoms, by reacting a O-(1-alkylthioethylimino)-N-methylcarbamate of the formula ##STR2## wherein R is as defined above, in the presence of a base, with sulfur dichloride or sulfur monochloride in an inert solvent, which process comprises carrying out said reaction in the presence of 0.01 to 0.5 mole of a compound selected from the group consisting of N,N-dialkylformamides, each containing 1 to 4 carbon atoms in the alkyl moieties, N-methylpyrrolidone, dimethyl sulfoxide, phosphoric acid tris-N,N-dimethylamide and tetramethyl urea, per mole of O-(1-alkylthioethylimino)-N-methylcarbamate of the formula II.The bis-[O-(1-alkylthioethylimino)-N-methylcarbamyl]-N,N'-sulfides of the above formula possess insecticidal properties and are suitable in particular for controlling pests of cotton plants and bluebottles.
摘要:
A clamp for fastening trim or protective strips on support surfaces which includes a single strip of sheet metal formed to three spaced, superposed legs, the outer legs being connected by a bridge, and the middle leg bent inwardly from the free end of the lower outer leg and extending toward the bridge and between the outer legs. The lower leg and bridge are slotted to slide or plug onto a shank of a T-shaped stud, the lower and middle leg clamping the top and bottom of the head of the stud. The upper and middle legs clamp a projection on the trim strip.
摘要:
The pollution content, for example, CO and NO.sub.x, of exhaust gas from spark ignition engines is decreased by a reactor and also by retarding ignition spark (a) during engine-idling solely as a function of pressure downstream of throttle valve and (b) during engine part-load solely as a function of pressure upstream of . At engine full-load only the normal spark timing of the engine operates. In this way the minimum effective exhaust gas reactor temperature is quickly reached and maintained during idling and part-load, but the reactor is not overheated when engine is at full-load.

The present invention relates to a method of obtaining protein preparations from sunflower seeds as well as protein preparations produced with the method. In the method the sunflower seeds are dehulled to a residual hull content of 5% by weight or dehulled sunflower seeds with a residual hull content of 5% by weight are provided. Mechanical partial deoiling of the dehulled sunflower seeds is carried out through pressing up to a fat or oil content of the dehulled sunflower seeds in the range 10 to 35% by weight. After carrying out one or more extraction steps with at least one solvent, a defatted flour containing protein is obtained as a protein preparation. Both optically and functionally the protein preparation has very advantageous properties which allow it to be used directly in the food product or animal feed sector.

This invention is directed to a method of removing dimethyl ether from an olefin stream. The method includes distilling the olefin stream so that the dimethyl ether is separated out of the olefin stream with propane. The olefin stream can then be further distilled to provide a polymer grade ethylene stream and a polymer grade propylene stream, with each stream containing not greater than about 10 wppm dimethyl ether.
