Title: Reactor stirrer for high viscosity polymer production - with separate frames at angle to each other with no central shaft, reducing unagitated material and improving prod. quality
Inventor: HIDEKAZU NAKAMOTO
IPC: B01F7/00
Filed: 1990-01-29
Abstract: A device (D) for producing a polymer with a high viscosity utilizes a cylindrical or conical reactor with an internal stirrer. The stirrer has a multiple of frame-like agitators mounted one above each other and offset with a specified angle between each frame. The elimination of a central carrying shaft between each agitator frame reduces the accumulation of unagitated materials and there is less adherence of polymer to the frames. A process (P) for producing high viscosity polymer in the reactor is claimed where agitation occurs until the final high viscosity polymer is obtd. USE/ADVANTAGE - (D) is used to produce high performance materials such as fluid crystal polymers and polyacrylates.  (D) reduces unagitated material and clinging of polymer to the agitator frame. Quality of product is thus improved.  (P) is simpler and therefore process costs are reduced.  (D) allows production of high molecular weight polycondensation products.

Title: Low temperature conductive ceramic material - based on barium-titanate is made of vary small grain size to improve breakdown voltage and homogeneity
Inventor: JAROCH UTE DIPL PHYS
IPC: C04B35/465
Filed: 1990-03-20
Abstract: The ceramic material consists of a Ba/Ca-mixed titanate with fine grains. The grains consist of a core of Ba-rich and a shell of Ca-rich titanate. The material is prepared by addition of CaCO3, pref. 15-30 mole.%, to the doped Ba-titanate and using standard ceramic processing. The mixed materials are calcinated at 800-1200 deg.C and sintered at a temp. in the range 1250-1450 deg.C. The proportions of the elements Ba, Ca, Sr and Pb to that of Ti are related as follows: (Ba+Ca+Sr+Pb)/Ti = 1. Sr and Pb are added to affect the transition temp. USE/ADVANTAGE - During calcination Ca-rich and Ba-rich titanates are formed alongsidem each other. During sintering the Ba-rich phases act as crystallisation seeds by building a Ca-rich shell around them. This process allows many seeds to be formed, which keeps the grainsize low, e.g. 5 +/- 2 micron. The process is used to mfr. material for low resistance PTC-resistors with a high breakdown voltage.

IPC: C02F11/13
Filed: 1990-05-18
Abstract: Process and apparatus are described for drying sludge, in which process the sludge in a vessel (1) is conducted from top to bottom by means of a loading device (2, 6, 8) and by means of a discharge device (3, 11) in the form of a sludge column with stable layers and is dried in the course of this in countercurrent by means of drying air entering at the bottom of the vessel through a ventilating base (16) furnished with orifices and leaving from the top of the vessel. The heat contained in latent and sensible form in the drying air conducted away from the vessel is transferred via a heat exchanger (13) to the drying air supplied from outside, so that the heat liberated during the drying on account of the remaining putrefaction process is sufficient to maintain the sludge in the vessel at elevated temperature. Part of the dried sludge removed from the bottom of the vessel (1) is mixed with the externally (2) supplied sludge by means of a mixing device (7), in order to adjust the initial consistency and moisture content. According to a particular embodiment of the invention, a second vessel of essentially the same type is provided, to the bottom of which can be supplied drying air withdrawn from the top of the first container and mixed as required with drying air directly supplied from the surroundings. The sludge to be dried can be initially fed to the first or the second of the two vessels and there subjected to a predrying and then transferred from the bottom of this to the top of the other vessel in each case and there subjected to a final drying. <IMAGE>

It may also contain Na polyphosphate Na2CO3, Na2SO4 and water glass. USE/ADVANTAGE - The technique is used for working up very fine (I) with very high oil contents (up to 50 (wt)%) and reduces the oil content to under 0.5%. The equipment and operating costs are lower than usual and classification and magnetic sepn. are unnecessary, making the method useful with nonmagnetic (I). Sepn. of the oil reduces detergent and water consumption. The oil and/or aq. coolant/lubricant can be recycled to the machining process esp. if the oil/water emulsion is easily broken.
