摘要： The method is particularly adapted for controlling the molecular weight of a product output from a polybutene reactor. The method includes the steps of: deriving from the operating parameter of a polybutene reactor system a formula which correlates molecular weight as determined by product viscosity or other parameters of the product output with operating variables such as temperature of the reactor and concentration of isobutylene in the reactor, which concentration can be controlled by the amount of catalyst, e.g., aluminum chloride, being fed into the reactor; monitoring (a) the temperature of the reactor, (b) the concentration of isobutylene in the reactor, (c) the flow of coolant supplied to the reactor for controlling the temperature thereof and (d) the feed rate of catalyst into the reactor; calculating with said algorithm the approximate molecular weight of the product output; determining if the desired product molecular weight is higher or lower than the calculated molecular weight; and, if higher or lower, altering, through use of the formula, the temperature and/or the concentration of isobutylene in the reactor to obtain the desired product molecular weight.Also the method can include the step of adding moisture to the feed or the reactor for lowering the molecular weight of the polybutene product output.The apparatus includes a reactor, a computer and various sensing, monitoring and control devices for carrying out the steps of the method.

摘要： Disclosed is a process for pelletizing ultra high melt flow crystalline polymers to produce dust-free, uniform ultra high melt flow crystalline pellet products. The process comprises feeding polymer into melting/mixing means, resulting in molten polymer. The molten polymer is transferred to a droplet forming means that produces droplets of the molten polymer. The droplets collect on a continuously moving cooling conveyer and solidify to form dust-free, uniform ultra high melt flow crystalline polymer pellets. Further, the process produces ultra high melt flow crystalline polymer pellets which are uniformly compounded.

摘要： A calcium carbonate granulation and a method for preparing a calcium carbonate granulation are provided. The method includes applying an atomized binder to powdered calcium carbonate in a fluid bed granulator at a relatively high atomization pressure to achieve a reduced binder droplet size, and drying the resulting composition at elevated temperatures in a fluidized bed dryer. The resulting granulation include porous granules having a lower density and reduced mean particle size with improved compressibility. In addition, the resulting granulation can be compacted into tablets having a hardness 50% greater than the hardness of tablets formed from commercially available granulations.

摘要： An apparatus and method allowing a first communication distance between transmitter and receiver for substandard short range control of a vehicle security module, and a second communication distance between transmitter and receiver for standard long range control of the vehicle security module. In this manner, the receivers of numerous vehicles may be programmed all to respond to the same common code, and the short range control used to activate only the vehicle(s) immediately proximate a short range transmitter. Thereafter, the receiver of a selected vehicle may be programmed to respond to a unique code, and the long range control used to activate the receiver of the selected vehicle at a longer distance from a long range transmitter.
