Abstract: The present invention generally relates to small arms technology and, more particularly, is concerned with hunting and sporting cartridges having plastic cases. The objective of the invention is increasing of the ballistic data and structural strength of the product with low price of its manufacturing. This problem is solved by supplying of the plastic cartridge case in the shape of thin-walled cup of cylindrical external surface and internal surface comprising three conical portions of length and taper increasing from the bottom having the opening for the primer with a dam-diaphragm separating the cartridge case part and the part for the primer installation. The dam-diaphragm thickness is selected within the range of 0,2 - 0,5 mm. The device for manufacturing of the plastic cartridge case contains a mold performed of a matrix forming the external surface of the cartridge case, a halfmatrix with conical casting opening which forms the cup bottom and a punch forming the internal surface of the cartridge case. On the halfmatrix is a cylindrical hollow pin forming a closed primer opening. The cylindrical hollow pin together with the punch form a ring spree.

Title: Method and apparatus for processing a received signal in a communications system
Inventor: EASTON KENNETH D
IPC: H04W88/00
Filed: 2001-11-20
Abstract: A receiver unit includes a first buffer that receives and stores digitized samples at a particular sample rate and a data processor that retrieves segments of digitized samples from the first buffer and processes the retrieved segments with a particular set of parameters values. The data processor is operated based on a processing clock having a frequency that is (e.g., then or more times) higher than the sample rate. Multiple instances of the received signal can be processed by retrieving and processing multiple segments of digitized samples from the first buffer. the receiver unit typically further includes a receiver that receives and processes a transmitted signal to provide the digitized samples and a controller that dispatches tasks for the data processor. The data processor can be designed to include a correlator, a symbol demodulation and combiner, a first accumulator, and a second buffer, or a combination thereof. The correlator despreads the retrieved segments of digitized samples with corresponding segments of PN  despreading sequences to provide correlated samples, which are further processed by the symbol demodulation and combiner to provide processed symbols. The second buffer stores the processed symbols, and can be designed to provide de-interleaving of the processed symbols.
