Abstract: An improved vehicle transmission which substantially reduces the noisy rattle normally produced by interengagement of the input shaft and the input drive gear of the transmission when the engine of the vehicle is operating at idle speed and the transmission is in neutral. The input shaft and the input drive gear are in constant driven relationship. In the inventive structure, the interengageable spline teeth of the input shaft and the input drive gear of the transmission are provided with a greater backlash than is normally used. The intermittent firings of the engine normally cause nonsynchronous rotation of the input shaft relative to the input drive gear with attendant engagement of their respective spline teeth. The increased backlash provides greater spacing between the interengaging teeth which substantially eliminates the engagement of the spline teeth and attendant rattle noise.

Abstract: A cylindrical phased array antenna system capable of scanning at rates faster than the information rate of signals being received so that no information is lost by the scanning process. The array is configured to add the capability to provide multidimensional separation of multiple signals and to eliminate the sensitivity loss due to sampling. The cylindrical phased array is comprised of the means to decompose the distribution of current on the radiator elements caused by wave incidence into component signals which are the Fourier spatial harmonics of the distribution, heterodyne means to differentially phase shift these component signals at rates exceeding 4 .pi. radians per cycle of the highest frequency present in the information content of the incident wave, and means to form multiple complex-weighted sums (beams) of the component signals.
