Abstract: There is provided a suspension polymerization process for production of polymer particles having a substantially uniform size, which process comprises steps of: 
applying regular vibration to a flow of a monomer liquid which has a specific gravity smaller than that of an aqueous dispersion medium and which is gushed through an orifice having at least one pore in the aqueous dispersion medium containing a suspension agent which comprises a water-insoluble inorganic material to form monomer liquid droplets having a substantially uniform size, 
introducing the aqueous dispersion medium containing the droplets in a first reactor comprising a recycling means which discharges the aqueous dispersion medium from a bottom of the reactor and recycles it to a top of the reactor and a means for agitating the aqueous dispersion medium containing the droplets, in which reactor the aqueous dispersion medium and the droplets therein are kept at a preselected polymerization temperature, 
under an effect of agitation which controls an amount of the suspension agent and an effect of the recycling aqueous dispersion medium an amount of which allows residence of the droplets in the first reactor during polymerization in the first reactor, partially polymerizing the monomer liquid so that the specific gravity of the   droplets does not exceed that of the aqueous dispersion medium while keeping the suspended condition of the droplets, 
discharging the partially polymerized droplets together with the aqueous dispersion medium from a lower portion of the first reactor and introducing them in a second reactor, and 
further polymerizing the partially polymerized droplets with sufficient agitation to mix them in the second reactor.

Abstract: A novel  Acinetobacter calcoaceticus  strain produces a polysaccharide type biosurfactant having emulsifying capacity in high yield, reduces litmus, is negative to oxidases, produces pale brown substances when it is cultured in an agar culture medium, and has an ability of reducing nitrates and of denitrification. The biosurfactant produced by the novel microorganism has emulsifying properties superior to the known biosurfactant produced by a known  Acinetobacter calcoaceticus  strain RAG-1. In addition, the strain makes it possible to produce the biosurfactant on an industrial scale.

Filed: 1990-10-17
Abstract: A system is provided for measuring both the temperature and pressure of fluid in a borehole utilizing a single small diameter tube extending from the surface to the desired downhole test location in a borehole. Downhole fluid pressure is transmitted through the small diameter tube, while a sheathed thermocouple or fibre optic line extending along the flow path of the tube is used for transmitting downhole fluid temperature information to the surface. A continuous surface read-out of both pressure and temperature is thus possible, and the temperature read-out may be used to both monitor downhole fluid temperature and increase the accuracy of the fluid pressure measurement system.

Patent EP-0444347-A2 (EP)
Inventor: BONANNI ROCCO
IPC: G02B6/38
Filed: 1990-12-07
Abstract: Described is a method for assembling multi-fiber array connectors. V-grooved silicon chips (11 and 12) are placed in a holder (10) which allows the chips to "float" with respect to each other and adjust to varying fiber diameters. Once the fibers (31) are inserted, the chips are clamped and cemented together with the fibers fixed in the grooves. 
     The opposite opening of the holder, as also seen in the view in FIG. 2 comprises a cantilevered section including a pair of cantilevered arms, 16 and 17. Each arm includes seats, 18 and 19, for loosely holding the top and bottom chips, 11 and 12, respectively. The seats have essentially the same length and width as the chips so that the chips will be aligned in the  x  and  y  directions. The separation of the cantilevered members, 16 and 17, however, is such as to leave a small gap, typically less than the fiber diameter, between the two facing surfaces of the chips. Further, since the cantilevered arms are free to flex slightly and/or the chips are only loosely mounted in the vertical (z) direction, the gap between chips can vary as the fiber array is inserted therein. Thus, the chips "float" within the holder to allow the chips to be aligned by the fibers and to compensate for any variations in fiber diameter. 
     The holder is typically plastic made by a standard molding process. Other materials could also be employed. The chips are inserted into the holder with the cantilevered section facing upward so that the chips fall into the seats, 18 and 19. The end of the cantilevered section is then deformed, in this example by heating, so that dimples, 24 and 25, are formed to keep the chips within the holder while maintaining the loose retention of the chips between the cantilevered members, 16 and 17.

Abstract: For the renewing of screw threads leading into a hollow space, the invention proposes to pass compressed air into the hollow space during the cutting of an enlarged screw thread, which compressed air is discharged through the opening in which the screw thread is cut. The chips developing during the cutting of the screw thread are passed to the outside by chip-removal grooves of the tool. This ensures that the hollow space remains free of thread chips. The method is especially suitable for the renewing of spark-plug threads.   <IMAGE>

Abstract: 2.1 The method is intended to enable identification of error-affected movement vectors without the need to perform extensive computing operations. Movement vectors which have an implausible value are to be replaced by a movement vector which has been determined through comparison and which very closely approximates the correct value. 2.2 The determined movement vector of an image block is compared with the movement vectors of the adjacent image blocks and checked for plausibility. The values of the movement vectors originating in adjacent blocks in each case with approximately the same amounts and the same direction are combined separately and a weighting is carried out which is dependent on the proximity relationship and on the similarity of the movement vectors. Mean values are formed from the amounts and directions of the movement vectors classified in this way and a weighting is allocated to them. The mean movement vector to which the greatest weight is allocated is used for comparison with the movement vector of the image block just processed. This mean movement vector is used as a replacement for a movement vector of the respective image block under consideration which deviates too far from plausible values. 2.3 An image subdivided into image blocks is processed in such a way that implausible movement vectors are eliminated. This leads to an increase in image quality in narrowband digital image transmission. <IMAGE>

Abstract: An imaging apparatus (A) generates volume image data which is stored in an image memory (B). An image memory access controller (30) withdraws selected pixel values from the volume image memory which it provides at a video processor (20) to formulate the appropriate video signals for display on a video monitor (C). An operator defines a volume on an operator controller (32). A plurality of interconnected polygons define the three-dimensional volume specified by the operator. The video processor converts these defined polygons into an appropriate display on the monitor. The polygons are selected to define a subregion to be viewed. The polygons are rotated about one or more of (x), (y), and (z) axes, scaled, and translated along these axes to select an orientation from which the polygon and enclosed data is to be viewed. The rotation, scaling and translation is stored (38, 40, 42). From each pixel interior to the projection of a visible polygon onto the screen, the coordinates of a sample in the polygon are calculated via the inverse of the stored rotation, scaling, and translation. The computed tomography (CT) value of sample and that of its neighbours are retrieved, interpolated, weighted with the surface gradient and illuminated on the screen. The polygons are compared and hidden surfaces removed (54). If retrieved pixel values are retrieved that correspond to air or other tissue that is not to be viewed, the access control means continues to step along the translated and rotated viewing direction ray until a pixel value is found which meets the air and non-viewed tissue viewing criteria (62). For a more lifelike image, shading is added (64) to data corresponding to one or more of the polygons.
