20120262909 | Multi purpose visual and audible signaling baton - A multi purpose visual and audible signaling baton having applicability to fire scenes, traffic and crowd control, police operations, military procedures, search and rescue operations, and event parking has a whistle and LED assembly. A controller and power assembly controls and powers the baton by directly responding to a plurality of modes including an audible sound generating mode as well as an audio voice button. The baton provides a high intensity colors that illuminate much like a neon tube. The baton can function as a flashlight or strobe light. Also, each light that is selected can be accompanied by a loud 100 dbA whistle, merely by pressing a button. The baton permits a user to select up to ten colors with a capability of five different sounds including verbal commands and the baton, with a radio transmitter, can communicate with a remote radio receiver due to a programmable microprocessor. | 10-18-2012 |
20130050993 | Attention getting baton with a flashlight - An attention getting baton with a one-piece hollow tubular structure that is waterproof, shock resistant, and lightweight. At a rear tubular part, there is a holding compartment with a ribbed rubber grip for ease in handling the baton. A front tubular part with ribbed groves guides illumination through the baton. A tubular shaped removable rear cap forms a slip fit connection for accessibility into the holding compartment. A high intensity flashlight, inserted into the holding compartment, communicates a high intensity light beam through the baton. When pushed, a button, mounted to the rear cap, switches the flashlight into a plurality of modes such as an on/off mode, a strobe mode, and a mode to generate help or an SOS signal. Thus, the baton has applicability to fire scenes, traffic and crowd control, police operations, military procedures, search and rescue operations, event parking, or just personal use. | 02-28-2013 |

The reactor system has one or more reactant vessels, an oligomerization reactor, a first pressure control device, a preheater, a second pressure control device, a distributor, and a flash tank. The one or more reactant vessels contain reactants contain a melt transesterification catalyst, a dihydroxy compound, and an activated diaryl carbonate. The reactor system is connected in the following configuration: (i) the one or more reactant vessels connected to the oligomerization reactor, (ii) the first pressure control device disposed between and connecting the outlet of the oligomerization reactor and the inlet of the preheater; (iii) the second pressure control device disposed between and connecting the outlet of the preheater and the distributor; and (iv) the distributor disposed at the inlet to the flash tank. The pressure in the preheater is controllable at a pressure intermediate between the pressure in the oligomerization reactor and the flash tank. | 04-02-2009 |
20090088540 | Monomer Solution for Producing Polycarbonate - A non-reactive monomer mixture is formed from a dihydroxy component having one or more dihydroxy compounds dissolved in a melted diaryl carbonate. The dihydroxy component has less than 600 ppb alkali metal, an acid stabilizer, or both less than 600 ppb alkali metal and an acid stabilizer. The dihydroxy compounds of the dihydroxy component and the diaryl carbonate are present in a mole ratio of from 0.9 to 1.1. The monomer mixture is at a temperature between the saturation point of the monomer mixture and the highest melting temperature of the individual dihydroxy compounds. The non-reactive monomer mixture can be stored and transported and then polymerized to form polycarbonate upon addition of a catalyst. | 04-02-2009 |
20090088549 | Monomer Solution for Producing Polycarbonate - A non-reactive monomer mixture has a monomer component dispersed in a melted diaryl carbonate. The monomer component has one or more monomer compounds having a melting point below the melting point of the diaryl carbonate. Furthermore, the monomer component has less than 600 ppb alkali metal, an acid stabilizer, or both less than 600 ppb alkali metal and an acid stabilizer. The monomer compounds of the monomer component and the diaryl carbonate are present in a mole ratio of from 0.9 to 1.1. The monomer mixture is at a temperature between the melting temperature of the lowest melting monomer compound and the melting temperature of the diaryl carbonate. | 04-02-2009 |

The monomer component has less than 600 ppb alkali metal, an acid stabilizer, or both less than 600 ppb alkali metal and an acid stabilizer. The monomer compounds of the monomer component and the diaryl carbonate are present in a mole ratio of from 0.9 to 1.1. The monomer mixture is at a temperature between the melting temperature of the lowest melting monomer compound and less than 5° C. above the melting point of the diaryl carbonate. | 10-01-2009 |
20090312503 | Method of Producing High Molecular Weight Polymer - The present invention provides methods of producing high molecular weight polymer. A method of forming polycarbonate includes the step of combining in a reaction mixture a diaryl carbonate, a transesterification catalyst, an aliphatic dihydroxy compound, and a diacid compound in a reactor system. The temperature and pressure of the reactor system are adjusted to a first reactor setpoints and the reaction mixture is monitored to detect initiation of the exothermic oligomerization reaction. The reactor setpoint are adjusted to second reactor setpoints after detection of initiation of the exothermic oligomerization reaction. The reactor system is maintained at the second reactor setpoints to allow the reaction mixture to react to form an oligomer mixture. The oligomer mixture is then introduced to a polymerization reactor system operating under melt polymerization conditions sufficient to polymerize the oligomer mixture to a Mw of at least 9,000 g/mol (PC) and to remove the phenolic byproduct from the oligomer mixture to form polycarbonate. | 12-17-2009 |
