Inventor: BERGFELD MANFRED DR
IPC: C07B61/00
Filed: 1994-07-29
Abstract: Gamma-butyrolactone is produced by catalytic hydrogenation of maleic anhydride in the vapour phase in the presence of catalysts based on copper chromite in reduced form, the reaction being carried out with the aid of an essentially uniform catalyst essentially derived from the 3 components copper oxide, chromium oxide and silicon dioxide. The ratio of CuO to Cr2O3 to SiO2 is preferably approximately 78 : 20 : 2. The concomitant use of an inert gas, such as nitrogen, as a diluent may be advantageous.

Abstract: A method for forming a grating in a photosensitive medium (18) such as a photosensitive optical fiber. The method comprises impinging a pair of interfering, actinic beams (15,16) onto the medium, and during the impinging step, advancing the illuminated portion of the interference pattern relative to the medium. The advancement is carried out without changing the phase, or registration, of the interference pattern. A grating having a spatially dependent refractive index perturbation (amplitude chirp) is produced by varying the dose (intensity) of actinic radiation received by the medium during the advancement.

Abstract: The invention relates to a method for making a weapon barrel (1) having a wear resistance internal coating (10) which is applied by means of an electrolytic method. In order to make it possible to apply relatively thick protective coatings in a simple manner onto the inner wall particularly of large-calibre weapon barrels (1) in those regions which are subject to high thermal stress, the invention proposes the incorporation of a recess (7) in a weapon barrel (1) which is prefabricated to an accurate calibre, in that region of the firing chamber (2) and of the calibre region (3) adjacent thereto which is to be provided with the protective coating (10), this being done by electrochemical material removal (electropolishing) and that this recess (7) subsequently be filled with the protective coating (10) electrolytically. The same electrode (4,12) is preferably used in this case for the electropolishing process and for the electrolytic process for applying the protective coating (10). <IMAGE>

Abstract: The invention relates to a hydraulic control valve, comprising a two position valve body adapted to be shifted - by means of a rotary movement of an actuating shaft - from one operative position to the other. According to the invention the shaft of the valve body carries a drive wheel segment extending through an arc that corresponds to the shift angle of the valve body, said wheel segment being in drive connection with the actuating shaft, spring means being provided to bias - at least in the final stage of a rotary shift movement in either direction - said wheel segment in de direction opposite to the shift direction. This enables the valve body to be shifted from one working position into the other in a reliable manner, by simply reversing the direction of rotation of an available rotating drive shaft.

Abstract: An unloading delivery valve (10) for incorporation in a fuel delivery passage to a compression ignition engine has a valve member (17) slidable in a bore (14) which forms part of the flow path of the delivery passage. The valve member has a head (18) having on its under surface a portion (19) shaped to cooperate with a seating (16) at an end of the bore. The valve head is spring loaded into engagement with the seating (16) and is lifted from the seating when fuel flows to the engine. An unloading collar (21) is mounted on the valve member and cooperates with the wall of the bore to determine the return flow of fuel which flows when the valve head moves into engagement with the seating. A drilling (24) is formed in the collar to modify the return flow and the drilling is positioned so that during flow of fuel to the engine, the fuel which flows through the drilling impinges on the valve head at a position inwardly of the shaped portion (19).

Abstract: The invention provides a method and apparatus for testing the chew-out strength of paperboard cores. The apparatus of the invention includes a clamping element (20) for clamping a tubular core (40) to prevent rotation thereof; a splined chuck element (18) in the form of an axially tapered member having a plurality of circumferentially distributed splines (34) for insertion into one end face (38) of the core (40); and a means (14, 22) for applying increasing torque at a controlled rate to the splined chuck element (18). A measuring means (76) measures the torque applied to the splined chuck element (18). In operation, increasing amounts of torque are applied by the torquing means (14, 22) until the splined chuck element (18) shears the end face (38) of the tube (40) resulting in chew-out of the core (40). The maximum torque force applied to the splined chuck element (18) provides an accurate indication of the chew-out strength of the core (40).

A first reaction product mixture is fractionated to remove MTBE as an overhead fraction. The bottoms fraction comprising unreacted methanol and tertiary butyl alcohol is passed to a second etherification reaction zone at a liquid hourly space velocity of 0.5 to 4. A second reaction product mixture is fractionated to recover additional MTBE.

Abstract: Sewage flows along a channel (2) in the direction from right to left and through an endless screening belt (4) located with its lower region in the sewage stream. The belt (4) consists of pivotally connected perforated screening elements (12) each consisting of a shorter part (14) and a longer part (16) connected at an acute angle to one another. The belt (4) travels anti-clockwise causing solid particles larger than the perforations to be carried upwardly on the shorter parts (14). When each screening element (12) reaches the upper region of the belt (4) the solids drop into a screw conveyor (30) which conveys them to a desired location. A rotary brush (24) and a liquid spray assist the removal of solids from the belt. Any solids which fall clear of the screw conveyor (30) fall back into the channel (2) upstream of the inlet region of the belt (4). This arrangement reduces the risk of solid sewage entering and polluting the cleansed liquid sewage effluent downstream of the conveyor belt (4). <IMAGE>

Abstract: Procédé autorégulé et à vidange automatique, permettant de filtrer une suspension liquide par le passage de celle-ci à travers un matériau filtrant granulaire. Le flux de la suspension est arrêté de sorte que la pression dans le système soit déchargée, ce qui facilite la sédimentation des particules enlevées dans le fond du filtre. Il est possible d'obtenir une sédimentation accrue des particules par le passage d'un flux d'air à travers le matériau filtrant. Ensuite, par inversion du flux du filtrat, on effectue une action de lavage à contre-courant du matériau filtrant, cette opération favorisant encore la sédimentation des particules. Le matériau filtrant peut être contenu dans un passage d'écoulement suivant un chemin généralement sinueux. Ce passage d'écoulement peut servir de site de décharge de déchets dans lequel on jette les déchets domestiques toxiques ou dangereux.
