Title: Wireless direct sequence spread spectrum digital cellular telephone system
Inventor: MAGILL DAVID THOMAS
IPC: H04J13/00
Filed: 1993-11-23
Abstract: Exceptionally efficient operation is achieved through the use of orthogonal CDMA. That is, a much larger number of users per MHz of bandwidth can be supported in a given geographical area than can be supported with conventional CDMA. While the theoretical concept of orthogonal CDMA is not new, the present invention is based on novel implementation techniques which makes orthogonal CDMA practical in an a short range mobile telephone environment where significant multipath fading exists.      Specifically, this invention provides novel techniques for establishing the time base, frequency, and power control necessary to achieve orthogonality. Use of a high power sounding burst on the outbound link permits: 1) antenna diversity selection to minimize the probability of a faded condition, 2) local frequency locking at the subscriber terminal which avoids the requirement for a costly precision frequency standard, and 3) essentially instantaneous inbound power control based on the outbound receive signal level. This is effective since time division duplexing is used and both transmission and reception take place on the same frequency. With the short frame structure and unique placement of the sounding burst the correlation between the outbound and inbound path losses is very high. Thus, according to the invention, the signal structure and control algorithms result in a greatly reduced signal level range at the base station/PBX to achieve high efficiency in a orthogonal CDMA system. Real world effects such as filtering, multipath time spread, and time base error destroy orthogonality and introduce a degree of cross coupling between supposedly orthogonal channels.      Thus, the invention provides accurately controlled power levels in this highly dynamic environment. This invention achieves this necessary objective for efficient operation.

Patent CA-2388615-A1 (CA)
Inventor: GRAFEN KARL
IPC: B01D25/00
Filed: 2000-10-20
Abstract: The invention relates to a filter press (1) with a stack of vertically aligned, horizontally displaceable filter plates (6). Neighboring filter plates (6) are interconnected by means of at least one respective connecting element and define a filter chamber between them. In a pressing position of the sealing edges, said filter plates (6) lie against one another and are displaced one by one into a discharge position by horizontally displacing at least one filter plate (6). In this discharge position, the horizontal distance of neighboring filter plates (6) is limited by the action of a coupling element (12) on a stop surface (20). The aim of the invention is to evenly and completely relieve all sealing edges. To this end, the filter plates (6) can be displaced from the pressing position to a relief position in which the sealing edges are detached from the pertaining sealing surfaces and in which the coupling elements (12) engage with a blocking surface (13) that prevents a further horizontal displacement. The engagement of the coupling elements (12) with the blocking surfaces (13) can be released by unlatching the pertaining connection elements (11) so that the neighboring filter plates (6) can be displaced further into the discharge position.
