Abstract: A process for the improvement in the utilization of carbon monoxide and for the utilization of propylene having varying grades of purity in the carbonylation of propylene with carbon monoxide and hydrogen fluoride to form isobutyryl fluoride in a carbonylation reactor whereby the effluent from the reactor is (a) passed into a first phase separator where the effluent is separated into an overhead gaseous stream and a bottom liquid stream which contains unreacted carbon monoxide, (b) the bottom liquid stream from (a) is passed into a second reactor where it is contacted with a gaseous stream which contains propylene and allowing essentially all of the propylene to react, (c) the effluent from the second reactor is passed to a second phase separator where overhead gases are separated from liquid bottoms, (d) the liquid bottoms from the second phase separator are passed to a degassing pot where overhead gases are removed and the liquid bottoms stream which is essentially isobutyryl fluoride is taken to recovery, (e) the overhead gases from (d) are optionally mixed with inert gases and the stream is recycled to the hydrogen fluoride fed to the carbonylation reactor and/or recycled back to the gaseous stream in (b), (f) the gases from overhead stream in (a) are passed to a compressor and then to the recycle gaseous stream from (e), (g) the overhead gases from (e) are divided into a first portion which is sent to recycle as in (e) and a second portion which is sent to a refrigeration unit where said second portion into a bottom stream of less volatile materials and an overhead stream of volatile materials, a portion of the bottoms stream is added to the isobutyryl fluoride stream for recovery in (d), and the overhead, less volatile stream from (g) is sent to waste disposal is described.

Abstract: A system for the contactless exchange of data between a transceiver and a passive data carrier is described. A prior data carrier comprises at least one digital memory and at least one digital control device for the memory. In it, the data carrier has a single-coil receiver circuit connected to a controllable switch device. In operation, the data carrier provides, in response to an electromagnetic a.c. field generated by a transceiver, via at least one rec­tifier,supply power for active components of the data carrier and clock signals for the control of digital components of the data carrier. According to the present invention, in order to provide for the possibility of bi-directional data exchange between a transceiver and a passive data carrier, and in general, to provide a universally applicable data ex­change system of the contactless kind, the transceiver is equipped with a modulator for amplitude modulating the a.c. field. The control device has two inputs for the supply of clock signals and data signals and includes level detectors cooperating with the inputs and arranged to allow the passage of an input signal voltage exceeding a pre-determined value as a valid input signal pulse. The coil is connected to the inputs through a two-branch divider so that the voltage   at the clock signal input is higher than that at the data signal input.

Abstract: The present invention generally relates to the mounting of windows in a frame, particularly to the mounting of windows of a vehicle, e.g. an automobile, in the body frame work. The invention provides a window ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and having the general cross section of an U-profile. This first bead is elastic but not plastically deformable. The first bead comprises in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences e.g. by covering it by a protection foil which is removed just prior to mounting the window.

Abstract: The present invention relates to an arrangement in revolving door assemblies, comprising a pair of part-­cylindrical wall portions (3,4) partly surrounding the rotational path of a revolving door (5) and partly defining a passage (P). Pairs of part-cylindrical wall panels (10,11;12,13) are provided in association with the part-cylindrical wall portions. Said wall panels are movable along paths concentric with the rotational path of the revolving door and are adapted to close and open the passage substantially in syncronism with the continuous rotation of the revolving door. Thereby passage will remain checked during said rotation, alternatingly by the revolving door alone and by said door in cooperation with wall panels of each pair. Hereby a draught-free passage will be maintained.

Abstract: Nitriles and oxides are provided from hydrocarbons by reaction with oxygen, air or preferably oxygen-enriched air and ammonia where a nitrile is desired, in the presence of a suitable catalyst. An alkane, eg propane, is converted to an alkene in a dehydrogenator. The product stream is introduced into an ammoxidation/oxidation reactor. The product formed therein is recovered in a conventional quench tower. The gaseous effluent from the quench tower is treated in a PSA unit to form a gas stream containing the unreacted alkane and alkene as well as a minor amount, of oxygen and nitrogen. The gas stream, which may or may not contain hydrogen depending on the adsorbent in the PSA unit, is introduced into a selective oxidation unit to remove the remaining oxygen and then recycled to the dehydrogenator. Hydrogen may be introduced into or removed from the PSA effluent, depending on the choice of the adsorbent, to obtain an optimum concentration for introduction into the dehydrogenator. A particularly preferred PSA system for use in the subject process comprises two parallel PSA units containing different adsorbents such that the gas stream formed in one contains all of the hydrogen in the gas phase from the quench tower. The feed to the PSA units is divided disproportionately so that the combined PSA effluent recycle streams contain the optimum concentration of hydrogen for the dehydrogenator.
