Abstract: REACTOR FOR HETEROGENEOUS SYNTHESIS AND METHOD FOR ITS OPTIMISATION            Inventors:  Umberto ZARDI and Ettore COMANDINI            Assignee:   AMMONIA CASALE SA, Lugano, Switzerland ABSTRACT   The reactor for heterogeneous synthesis, in particular for the catalytic synthesis of ammonia, methanol, and similar substances, consisting of at least an outer shell, at least an internal cartridge formed preferably of modular cartridges, each comprising a catalytic bed consisting of a granular catalyst contained between a closed lower bottom and two con-centric cylindrical walls of which the outer wall is perforated for the whole of its axial length and the inner wall has a perforated length shorter than the outer wall, so that each catalytic bed is run through by a split portion of the reaction gas in a zone with prevalently axial flow and by th?  remaining split gas portion in another zone with preva-lently radial flow, the zone with prevalently axial flow of each cataly-tic bed acting also as sealing pad for reaction gas, is characterised by the fact that in the cylindrical space comprised between the inner walls of at least one of the n catalytic beds is inserted a heat exchan-ger lapped on one side by the reacted has coming directly from the relevant catalytic bed and, on the other, run through by water or other liquid fed from outside.          The method is so arranged that heat is removed at a high level in situ so as to obtain at the same time the optimisation of reaction conditions and the reduction of the catalyst volume in each catalytic bed and, in addition, an even more accurate control can be made of the temperature of the gas reacted on one bed and entering the next catalytic bed, by controlling the amount of hot gas reacted on a bed sent to the exchanger associated with the same bed.

Abstract: ABSTRACT         A process is disclosed for preparing resin extended pigments containing from 10% to 75% and preferably 25% to 50% by weight, based on the amount of pigment and resin present.  The crude pigment and resin are premilled dry, such as in a ball mill, in a manner equivalent to that used to prepare small particle size highly aggregated pigment.  Following premilling the pigment and resin are milled in an organic liquid capable of ripening the pigment particles to pigmentary size or simply improving their crystallinity which organic liquid at 30°C can dissolve no more than 5 g/l and preferably no more than 1 g/l of the resin.

Abstract: ABSTRACT           A process for providing a low haze, high transparent, high heat-resistant laminate by forming a preform laminate 200 of a high heat-resistant layer covered on both surfaces by a non-glass protective layer 210 with at least one said layer being an as-cast acrylic layer.  This combination can be readily stored for long periods of time or used immediately after the formation thereof by peeling off one of the as-cast acrylic layers 210 and applying a trans-parent flexible adhesive layer 214 thereto.  A transparent material 218 can be added to the adhesive layer.  Many other combinations and laminates can be formed from the preform high heat-resistant lami-nate since during the preparation thereof, haze is not introduced to the transparency via moisture, and con-tact with haze-forming release coatings is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE           There is described a device for tethering an animal which includes a suspension element having a base to be hung from a fixed structure, two arms having upper ends fixed to the base and lower ends, the base and the arms definine a plane, a bottom piece for connection to the fixed structure, first pins supported by the arms adjacent to the lower ends and at right angle to the plane and two legs forming together with the bottom piece a yoke.  Each of the legs comprises a top part, a lower part, a first hinge connecting the top part to the lower part and a second hinge connecting the lower part to the bottom piece.  Each of the top parts is hinged about one of the first pins and has a portion projecting above the first pin and a portion projecting under the first pin, the first hinges and the second hinges allowing movement of the lower parts both in the plane and outside the plane defined by the base and the arms.  Each of the legs also includes second pins supported by the arms parallel to the plane.  The present tethering device further comprises a control member having a base and two arms.  The arms of the control member have ends fixed to the base of the control member and ends hinging about the second pins, the control member thus hinging about the second pins with respect to the suspension element between a first position in which the base of the control member is lower than the second pins and a second position in which the base of the control member is higher than the second pins.          The control member acts on the portions of the top parts pro-jecting above the first pins and retaining in its first posi-tion the portions projecting above the first pins in a con-verging position and retaining in its second position the por-tions projecting above the first pins in a parallel position.          The control member further includes a spring having two ends, one of the ends being connected to the control member and the other of the ends being connected to the suspension element.          The spring passes through a dead position when the control member moves from its first position to its second position.          On one side of the dead position, the spring pulls the control member to the first position and on the other side of the dead position, pulls the control member to the second position.
