Title: Method of making interpolymers and products made therefrom
Inventor: VANDERLENDE DANIEL D
IPC: C08L23/06
Filed: 2002-03-15
Abstract: A polymerization process comprises contacting one or more olefinic comonomers in the presence of at least a high molecular weight catalyst and at least a low molecular weight catalyst in a single reactor; and effectuating the polymerization of the olefinic comonomers in the reactor to obtain an olefin polymer. Preferably, both catalysts have the ability to incorporate a substantially similar amount of comonomers in the olefin polymer. The polymers produced by the process may have a relatively higher level of long chain branching while maintaining a relatively narrow molecular weight distribution, i.e., MWD less than about 6. These interpolymers may exhibit processability similar to or better than LDPE but have physical properties similar to metallocene catalyzed polymers.

Abstract: In an apparatus according to this invention, a single synchronous photography timing controller supplies cameras for synchronous photography, with an external clock signal for controlling progress of a photographic sequence, an external reset signal for resetting the photographic sequence, and an external trigger signal for starting high-speed photography, all in a coordinated manner. Consequently, a timewise corresponding relationship is maintained between the external clock signals and between the external reset signals being supplied. The external reset signals reset photographic sequences of the respective cameras, so that the photographic sequences also progress in a timewise corresponding relationship. The high-speed photography of the cameras started by the external trigger signals supplied in the coordinated manner progress in a strictly timewise corresponding relationship. Thus, the cameras are synchronized accurately to perform the high-speed photography.

IPC: H01Q1/00
Filed: 2004-06-09
Abstract: " The antenna designed to transmit or receive an electronic intelligent signal such as voice, video or computer information, will transmit said signals faster than light at infinite speed over distances of several kilometres on the average when hooked up to regular communications equipment. Other than this invention no such equipment exists in the world that we know of. In the field of science, communications and electronics in general, it often becomes necessary to somehow compensate by electronic means for time delay factors which are caused by the fact that regular radio signals are not instantaneous, but are limited to the speed of light. To give an example if in the future a manned mission to Mars will be made, the astronauts can talk directly to the control centre in Houston without having to wait so many minutes for a reply. The faster than light antenna eliminates this time factor."
