Abstract: 1,143,856. Alcohols and ketones by oxidation of hydrocarbons. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 24 May, 1967 [24 May, 1966; 13 Dec., 1966], No. 24241/67. Heading C2C. Alcohols and ketones of saturated hydrocarbons containing from 5-8 C atoms such as cyclohexane, cycle-octane, cycloheptane, hexane, octane, heptane, iso-octane, methyl and dimethyl cyclohexanes are prepared by a process comprising (a) contacting the hydrocarbons at a temp. of from 100-220‹ C. in the liquid phase with a gas containing molecular oxygen, preferably at a concentration of 1-25% in admixture with nitrogen, in the presence of a boron compound such as boric acid, anhydride or an ester, (b) hydrolysing the reaction product to yield an organic and a boric acid aqueous phase, (c) crystallizing and separating boric acid from the aqueous phase thereof and recycling to the oxidation zone and (d) fractionating the organic phase to separate the alcoholic and the ketonic product; wherein the aqueous phase resulting from the hydrolysis step is subjected to a distillation of from 5-40% of its total weight before or during the crystallization of the boric acid. The distillate is preferably used to wash the organic phase resulting from the hydrolysis and then recycled to the hydrolysis zone.

Title: Auxiliary magnet for permanent magnet loudspeaker
IPC: H04R9/02
Filed: 1968-10-16
Abstract: magnet system comprises ring shaped axially magnetised permanent main magnet, adjoining soft iron plate having centrally arranged on one of the plates a soft iron core enclosed by the main magnet and the other plate in which the latter with the core form the active air slot. Against at least one of the plates an auxiliary magnet is fixed, which is magnetised mainly in the opposite direction. The auxiliary magnet at least partly covers and surrounds the plate and the magnetising device of the auxiliary magnet is adapted to the shape of the plate and stands perpendicularly on its surface. Specif. the auxiliary magnet is composed of a cylindrical disc magnetised in axial direction and has radially magnetised ring solidly supported by it. A completely scatter-free loudspeaker element is formed in this way in a simple manner by producing the auxiliary magnet in the form of a cap, placed over the plate during assembly.

Title: Grippers for automatic rapier looms - have angle section frames preventing interference with or from warps or reed
IPC: D03D47/23
Filed: 1975-09-19
Abstract: The feeder and takeover grippers on the lances of automatic looms have an "L"-section, the one flange of which is intended to move parallel to the reed, whilst the other moves parallel to the sley race. On the feeder there is a guide plate for the weft, above a pivoting spring-loaded clamp for holding the yarn against the bottom flange. The takeover gripper has a projecting hooked beak with a profiled surface against which a pivoting clamp presses, and both grippers have projecting details working with cams fitted to the sley. The grippers clamp the weft securely and without damage, irrespective of its characteristics, and holds it clear of the reed. They cannot interfere with the warp threads, and cannot be opened by the warps either. There is ample tolerance at the changeover point, and the grippers are self-cleaning so that fly and dust obstruct their working.

Title: Proportioning apparatus for crumbly, compression-moulded animal feeds and crops (e.g. seeds, maize etc.)
IPC: A01K5/02
Filed: 1993-04-22
Abstract: Proportioning apparatus for feed, which exists both in a crumbly and a compression-moulded state or consists of crops (for example seeds, maize etc.), which allows the dispensed portion to be adjusted, dispensing being possible by operation of a tubular slide construction. A tubular (usually rectangular) slide upon operation shuts off the inflow of the feed in such a way that the separate feed particles always have a free space to escape to, so that seizing up owing to feed particles becoming jammed is impossible. The prepackaging of feed is thus dispensed with. The installation does not require an energy supply.
