Title: Ziegler-Natta-catalyst component, its preparation and use
Inventor: SORMUNEN PEKKA
IPC: C08F4/658

Granted: 1996-03-13
Abstract: The invention relates to a procatalyst of a catalyst system for the polymerization of olefins consisting of magnesium halide particles, to the surface of which has been attached a titanium compound and optionally an electron donor. The procatalyst of the present invention is in the form of substantially amorphous spherical magnesium particles, which are activated with a titanium compound such as a titanium alkoxide. The magnesium particles are prepared by spray-crystallization of a mixture of magnesium halide and alcohol and optionally a donor. The complex particles obtained after treatment with an organometallic compound are easily and efficiently activated by titanium alkoxide and are more durable to impurities.

Abstract: Process for regeneration and the corresponding apparatus of a reforming catalyst, the reforming being carried out in at least two reactors in series through which the catalyst and the feedstock travel in succession, the pressure in the first reactor through which the catalyst and the feedstock pass being at a pressure of between 3 and 8 bars. 
<??>The regeneration process is characterised in that the spent catalyst encounters successively a first zone 101 containing a moving and radial combustion bed, a second zone 105 containing a moving and radial combustion bed, a zone 107 containing a moving axial oxychlorination bed and a zone 116 containing a moving axial calcination bed, and in that in the combustion zones the catalyst is treated at a pressure substantially equal to that prevailing in the said first reactor, the combustion gases are removed from the second combustion zone and are conveyed to a scrubbing loop after having been mixed beforehand with the gases drawn off from the oxychlorination zone and from the calcination zone, in that in the oxychlorination zone the catalyst is treated with a mixture of a gas originating from the calcination zone and of a gas based on a chlorine-containing compound, the streams being concurrent and in that in the calcination zone the catalyst is treated countercurrentwise with at least a proportion of the gases originating from the scrubbing loop.

Title: Back draught security device for flue breaker in a boiler with atmospheric burner
IPC: F24H9/20
Filed: 1990-07-20
Granted: 1993-09-22
Abstract: The invention relates to a back draught security device for the flue breaker (9) of a boiler (1) with an atmospheric burner (3), comprising a control thermostat serving to detect an abnormal rise in temperature, and making it possible in this case rapidly to interrupt the electric supply of the burner, as well as a delay means which allows resetting with a given delay. According to an essential aspect of the invention, the thermostat (150) is arranged against a wall (17) of the flue breaker (9) in order to detect the heating of a predetermined zone of the latter which is greatly stressed in the event of back draught; the thermostat (150) acts directly on the electric supply of the burner (3) when this heating reaches a given threshold, and the delay is ensured by a thermal insulation device (160) arranged against said predetermined zone of the wall in order to slow its cooling, the thermal inertia of this insulation means being selected so that the delay obtained corresponds at least to the given delay time. Application to flue breaker boilers with atmospheric burners. <IMAGE>

Abstract: The burner comprises a tubular body composed of an inner bush (12) and an outer bush (10). The inner bush (12) carries a spray nozzle (11), an ignition electrode (23) and an observation tube (40). An annular space (E) arranged between the two bushes provides the inlet for a flow of oxidiser. A primary flow (A) of supply of oxidiser gas is led in through apertures (15) towards a deflector plate (18). This arrangement permits an area of toric-cyclonic combustion (33) to be obtained by virtue especially of the existence of slots (16) let into the deflector plate (18) and inclined blades (13) mounted in the space (E) located between the inner bush (12) and the outer bush (10). The advantages are a better homogeneity of the mixture, an increase in the dwell time of the mixture in the combustion area and better recycling of the combustion gases. <IMAGE>

Abstract: A machine for sorting refuse comprises a rotatable drum (10) having several succeeding processing stations (5, 6, 7) located between an inlet (3) and an outlet (4) and each including one or more rotatable shafts (8) the circumferential surfaces of which are equipped with projecting goods-processing means and which are mounted at openings in the wall of the drum, the processing means being adapted to cooperate with the edge portions of the drum wall defining said openings, so as to bring about a processing action on goods fed from the inlet towards the outlet. The processing means of the shafts (8) in a first station (5) most adjacent the inlet (3) are smaller than the corresponding processing means in the following station (6) in order, in said first station, to separate fine goods, while allowing coarser goods, during the feed of the goods from the inlet towards the outlet along the bottom of the drum, to pass on for separation in a succeeding station or stations.

Abstract: Layers of transparent dielectric material having immobilised thereon haptens or hapten analogues are useful in devices for the immonassay of haptens which are based on the principle of frustrated total reflection. The layer of transparent dielectric material forms part of a biosensor comprising a) a cavity layer of transparent dielectric material having immobilised upon it a hapten or hapten analogue, b) a dielectric substrate, and c) interposed between the cavity layer and the substrate, a dielectric spacer layer, the arrangement being such that, when the interface between the substrate and the spacer layer is irradiated with light such that total reflection occurs, the total reflection may be frustrated by the propagation of a resonant guided mode within the cavity layer.

Abstract: Individual frame profiles (1, 21, 27, 30, 34) can be braced against one another to form an exchangeable frame by means of a bistable spring clamping element (9). An exchangeable frame of this type has at least two separation joints (10) which are arranged at opposite points on the frame, each have at least one bistable spring clamping element and thus allow rapid opening or closing of the separation joint (10). For the purpose of guidance, the frame profile has two inwardly directed, plate-type projections (2, 3) which are arranged parallel to the picture plane. The space between these projections (2, 3) serves as a guide space (12) in which a plate-type guide part (6) is arranged movably towards at least one side of the frame. Located in the movable side of the guide part is a connecting link cutout (7) which is designed in terms of shape such that a power accumulator (8) is mounted by one end (23b) so as to be axially rotatable in a counter bearing (19) while the other end (23a) is arranged so as to be displaceable along the path (16) of the connecting link from one of the two power accumulator end positions (15b) to the other (15a) or vice versa, the separation joint (10) being held in the closed position (15a) under a prestress of the power accumulator (8). The power accumulator (8) and frame profile projections (2, 3), connected to one another by a connecting pin (13), together with the guide part (6) and the connecting link cutout (7) arranged therein form the bistable spring clamping element (9). <IMAGE>

The instrument further includes an outer safety shield (201) having a rounded distal end (203) for preventing the puncture of a surgical tissue bag or from unintentionally cutting tissue by the attending physician. The outer shield has a channel (207) across the distal end through the hollow passageway therein for feeding tissue into the cutting edge and controlling the vacuum applied to the tissue. Vacuum or suction control ports (210) are included at the proximal end of the inner cutting member tube and stationary sheath for also controlling the amount of vacuum or suction applied to the tissue. The surgical cutting instrument includes a control handle (118) for grasping by the physician. A removable collection chamber (212) is connected to a coupler connected to the stationary sheath for collecting tissue therein. The inner cutting member tube extends through the collection chamber to a drive motor (123) or to a remotely positioned rotary drive mechanism.
