Granted: 1999-10-25
Abstract: A catalytic distillation process for the production of methyl tertiary butyl ether (MTBE) from the reaction of tertiary butyl alcohol (TBA) and methanol (MeOH) is provided. A mixture of the reactants is fed into the reaction distillation column, preferably below a bed of acid ion exchange resin catalyst which constitutes a reaction distillation zone. In the reaction distillation zone the reactants contact the acid ion exchange resin catalyst and catalytically react to form MTBE and water. Some isobutene may also be formed. The acid ion exchange resin catalyst is in such a form as to act as both the catalyst for the reaction and distillation structure for the fractional distillation. A frothing liquid level is maintained in the catalyst bed to provide good contact and wetting of the catalyst.

Abstract: A brake lever for an S-cam brake has a worm wheel (3) engaging the S-cam shaft and a worm screw (4) meshing therewith. A clutch wheel (6) on the worm screw forms a clutch (8) therewith under the bias of a compression spring (9). A control movement is transmitted from an external reference point to the clutch wheel via a pinion (15), a carrier wheel (16) and a control screw (18), the common axis of these three parts being perpendicular to the worm screw, wherein the control screw meshes with the clutch wheel. The carrier wheel can be turned relative to the pinion an angular distance corresponding to the desired slack and is biassed to one end position by a torsion spring (17), which is also used to engage a one-way clutch (19) between the carrier wheel and the control screw. <IMAGE>

Date Jun. 15, 1989.Disclosed is an instrument for measuring accelerations, with the aid of which changes in motion in the three axes of space can be measured with selective sensitivity. In order to detect multi-dimensional changes in motion, three micromechanical sensors, each sensitive to the acceleration in a selected direction, are integrated in a crystal. The sensors are composed of torsion bars having masses eccentrically attached thereto, which, in the event of changes in motion, exercise torques about the axes of the torsion bars. The torques are measured with the aid of integrated piezo-resistances. The planar integration of the acceleration meter permits integrating the evaluation circuit on the same semiconductor surface. Acceleration meters of this kind are fabricated with the prescribed process in planar technology with the aid of epitaxy, lithography and anisotropic etching methods. High precision and high miniaturization make this acceleration meter suited for application in overland and aviation navigation and for component positioning in robotry.

Abstract: A millimeter wave sensing device is disclosed comprising a local oscillator source generating a millimeter wave signal which is mixed with millimeter wave radiation reflected from or emitted by objects in a field of view. The mixing is performed in a staring array of mixer/detector elements which need not be mechanically or electronically scanned to generate signals responsive to the entire field of view. In a first embodiment of the invention, the device detects millimeter wave radiation emitted by or reflected from the object to be imaged. In a second embodiment of the invention, the oscillator used to provide the local oscillator signal is also used to illuminate the field of view. In the second embodiment of the invention, the oscillator signal is preferably linearly polarized, and a polarizing grid is used to separate the local oscillator signal and illumination beam and direct them in a simple and efficient manner. A twist reflector may also be used to rotate the polarization of a portion of the beam to direct it onto the mixer/detector array for mixing with the received signal from the field of view. Improved constructions of millimeter wave source and mixer/detector elements are also disclosed, which greatly simplify construction of the device.

Abstract: Highly efficient cationic liposomes have been developed as an improved delivery system for biologicallyactive reagents. A novel structure, the sandwich liposome, is formed and comprises one or more biologically active agents internalized between two bilomellar liposomes. This structure protects the incoming agent and accounts for the high efficiency of in vivo delivery and for the broad tissue distribution of the sandwich liposome complexes. These novel liposomes are also highly efficient carriers of nucleic acids. By using extruded DOTAP:cholesterol liposomes to form complexes with DNA encoding specific proteins, expression has been improved dramatically. Highest expression was achieved in the lung, while increased expression was detected in several organs and tissues.

Abstract: Process for the improvement of the sulphur yield of an assembly which produces sulphur from from H2S and which consists of a sulphur plant (1), an oxidation and hydrolysis unit (2) and a purification unit (3). Said sulphur plant (1) in producing sulphur provides a residual gas (17b) which incorporates H2O, COS and/or CS2 and H2S and SO2 in a mol ratio of H2S:SO2  >/=  2:1. Said residual gas passes into the unit (2) on a H2S oxidation and COS and CS2 hydrolysis catalyst which functions between 180  DEG C and 700  DEG C, in the presence of air (47), thus producing a residual gas (38) free of COS and CS2 and incorporating H2S and SO2 in a mol ratio which is kept equal to 2:1 by regulating the air flow (47). The residual gas (38) is introduced into the purification unit (3), in which H2S and SO2 are made to react in order to produce sulphur and to obtain a purified residual gas (45).
