Patent EP-0272733-A1 (EP)
Inventor: COENRAETS BENOIT JAQUES
IPC: E06B9/82
Filed: 1987-12-03
Abstract: A device having a shutter windable around a spindle and especially adapted to close a bay or other opening by the unwinding of the shutter, the same having flexible side edges which project beyond the shutter plane and which are retained with reduced friction in substantially continuous guideways during the unwinding and winding up of the shutter, that shutter edges may disengage from their guideways when subjected to a predetermined pull transversely to guideway. Each guideway has near and upstream of the shutter spindle an access passage through which the projecting edge of any shutter which has disengaged from the guideway can re-engage, as the shutter winds around its spindle, in that part of the particular guideway concerned which is disposed beyond the passage.

Abstract: The present invention is concerned with new polymers comprising about 7 to about 22 percent by weight vinyl acetate units, about 15 to about 35 percent by weight vinyl alcohol units about 35 to about 57 percent by weight vinyl acetal units, and about 7 to about 23 percent by weight of vinyl hemi­acetal units. 
     These new polymers which differ from known polymers by the specific ranges of the acetate, alcohol and acetal units in combination with a hemiacetal content of about 7 to about 23 percent by weight show better solubilities in formaldehyde, and can be prepared with a higher degree of reproducibility than the prior art polymers.

Abstract: A process is provided for the distillation of a composition containing 4-hydroxyacetophenone and hydrogen fluoride in the presence of an alkane assisting solvent having from 4 to 16 carbon atoms e.g. n-hexane or n-octane. The process is carried out to obtain an overhead vapor containing alkane solvent and most of the hydrogen fluoride in the feed, and a liquid residue containing most of the 4-hydroxyacetophenone in the feed. The overhead vapor is condensed to form two immiscible phases, one containing a preponderance of hydrogen fluoride and the other a preponderance of alkane solvent, with the latter phase being returned to the distillation as reflux. The liquid residue also separates into two immiscible layers, one containing most of the 4-hydroxyacetophenone in the feed which is recovered and the other a preponderance of alkane solvent.

Abstract: A fluid discharge apparatus for selectively providing a stored fluid to a working environment for the fluid includes a container (12) for storing the fluid. The container is arranged as a metal thimble with longitudinal score lines (16) evenly spaced about its circumference. A weight (18) is attached to one end of the thimble to provide a force on the thimble in a longitudinal direction as a result of a corresponding acceleration of the thimble. The scoring lines produce stress concentrations and serve to weaken the thimble in its radial direction. The longitudinal force produced by the weight during acceleration results in a collapse of the thimble and a rupture of the walls of the thimble along the score lines to produce exit orifices for the fluid stored in the container. If the fluid is an electrolyte, an the fluid discharge appratus is used in a reserve activated battery to store the electrolyte until the acceleration induced collapse of the thimble, the electrolyte is delivered from the ruptured thimble to adjacent electrodes (2, 20) to activate the battery.

    a device (15-17) for monitoring the intensity of the current (I) flowing in the primary winding (11) of the i­gnition coil (10), 
    electrical sensors (3-6) which provide signals indi­cative of the operating conditions of the engine, and

The con­trol unit (7) is also arranged to pilot the commutator device (13) so that, each time a spark needs to be gene­rated, the flow of current in the primary winding (11) of   the ignition coil (10) is stopped when the magnitude of this current has reached the value (I fi ) which is asso­ciated in the memory devices (8) with the prevailing ope­rating conditions of the engine, indicated by the sensors (3-6).

Abstract: Process for the conversion and working up of a mixture of organic matter, anorganic matter and water to a nearly dry product, whereby the mixture is contacted with an oxygen containing gas and put to reaction in a reaction section (9) at temperatures between 200 and 320 degrees Celsius, pressures between 40 and 125 bar and reaction times between 300 and 5400 seconds. After reaction the mixture and gas are separated on the one side in a slurry phase and on the other side water vapour containing gas-phase. The heat in the latter is used for heating of the mixture and for evaporation of water from the slurry phase. Therefor the latter is led to an evaporation section, which is equipped with evaporation means and which may consist of various units, of which at least one unit contains a fluidized bed (16). Organic matter and inorganic matter, emanated from the slurry phase are caught in this bed. The evaporation section is operated at lower temperatures and pressures than the temperature and pressure of the slurry phase and gas phase immediately after reaction. Parts of the fluidized bed mass are discharged periodically or continuously as a nearly dry matter.

IPC: H01S3/113
Filed: 1988-06-10
Abstract: A passive laser Q-switch (12) is fabricated from a crystal (22) which can form saturable color centers (24), 
such as 
lithium fluoride The arbitrarily long crystal (22) is irradiated with electrons from the side, or radially, to impart 
a radial 
distribution of saturable color centers (24) therein, with the highest density at the periphery of the crystal (22). 
Optionally, 
the crystal (22) can also be irradiated axially with electrons (34) or in any direction with another form of radiation 
having 
greater penetration into the crystal (22), such as gamma radiation, to establish a base level of saturable color 
centers (24) 
throughout the crystal (22). The crystal (22) having the radial distribution of color centers (24) acts as a Q-switch 
(12), but 
additionally tends to reduce beam divergence and increase the brightness of the laser beam by virtue of the 
non-linear 
bleaching mechanism.
