Title: High productivity process for production of maleic anhydride
Inventor: EBNER JERRY R
IPC: B01J8/06
Filed: 1992-07-02
Abstract: An improved process for the manufacture of maleic anhydride by catalytic oxidation of a nonaromatic hydrocarbon having at least four carbon atoms in a straight chain, in which a gas containing oxygen and hydrocarbon is passed through a fixed catalyst bed in a tubular reactor. The activity of the catalyst bed is graded in such manner that the reactor can be operated at an initial (feed gas) hydrocarbon concentration of over 1.5 % by volume, an integrated average temperature difference between gas and cooling fluid of at least about 15  DEG C over that portion of the bed in which the gas temperature exceeds the cooling fluid temperature, and a productivity of at least about 5.0 lbs. maleic anhydride per hour, without the temperature difference between the gas and the cooling fluid exceeding 80  DEG C at any point in the catalyst bed during the course of the reaction. Preferably, the catalyst activity and the gas permeability of the bed vary in the direction of gas flow so that both the catalyst activity and the pressure drop per unit distance are lower in a critical region, where the combination of temperature and hydrocarbon concentration could otherwise cause the reaction to proceed at an excessive rate, than they are in a region of low temperature and low hydrocarbon concentration. Significant and unexpected improvement in reactor performance is achieved by the combination of a graded catalyst charge and incorporation of a catalyst modifying organophosphorus compound in the hydrocarbon feed.

Title: Thread feeding device for textile machines
Inventor: GHIARDO FIORENZO
IPC: D03D47/34
Filed: 1989-02-10
Abstract: Improvements are introduced in the adjustment of the motor speed in weft feeders for weaving looms, fo the type wherein a weft yarn reserve, formed of evenly and distinctly spaced turns, is wound on a rotary drum held stationary, by means of a winding arm caused to rotate by said motor, said yarn reserve being controlled by photoelectric means, positioned close to the yarn outlet end of said drum, which adjust - in cooperation with means detecting the rotations of the winding arm - the motor speed of the feeder. In order to obtain, in such a weft feeder, a winding with no tears nor overlapping of turns, with a uniform running speed and in a relatively simple and economic manner, amongst the signals from said photoelectric means (11, 12), those (316, 328) produced by the advancement of the turns (3) of the yarn reserve (4) are discriminated, in an electronic circuit, from those (322) produced by the passage of yarns (3A) drawn from said reserve by the loom, said second signals (322) being used - in combination with the signal (33) generated by the means detecting the rotations of the winding arm (2) - to determine the speed of the motor (6), and said first signals (316, 328) being used to adjust said speed, so as to guarantee the constant presence of an adequate yarn reserve on the drum.

Title: Anchor rail for construction engineering
Inventor: FRICKER SIEGFRIED
IPC: E04B1/41
Filed: 1993-08-19
Abstract: Known anchor rails for construction engineering with at least one projecting anchor consist of a U- or C-shaped rail section to which is interlockingly linked a massive anchor bolt by upsetting or another deformation process. Deforming the massive anchor bolt, in particular in the area of the back of the rail and of the free-standing anchor head, is complicated and expensive and requires costly deforming machines. The invention aims at substantially simplifying the construction and manufacture of such anchor rails without affecting  the carrying capacity of the anchor rail. For that purpose, at least the anchor shaft (4) is constituted by a tubular section; the tubular anchor foot (3) preferably extends through an opening (6) of the anchor rail (1) and interlockingly engages the latter by means of at least one shoulder (7) shaped at the end of the tubular section (2).

Title: Connecting receptacle and connecting cable for connecting apparatus to data network
Inventor: PHILIPP GERD
IPC: H01R13/646
Filed: 1994-06-29
Abstract: As connecting device for a data network, a connecting box (15) contains a circuit board by means of which two BNC sockets (16, 17) and at least one switched socket (18) are connected to one another. In order as far as possible not to interrupt the coaxial system of the data network in the region of the connecting box (15), the circuit board is constructed as a multilayer board, with the conductor tracks (43) extending between two shielding conductor surfaces (41, 42). The switched socket (18) is surrounded for the same purpose by a tightly fitting screening plate (44). In the case of the associated connecting cable, the plug-in part (24) of the plug (23) is likewise surrounded by a screening plate (46), with the result that the coax-like conductor guidance is continued here, as well. The connecting device therefore reliably meets the transmission requirements, such as immunity to radiated interference and low signal distortion. <IMAGE>
