Title: Automatic filter press
Inventor: KUPKA DIETER
IPC: B01D25/12
Filed: 1989-11-16
Abstract: Abstract of the Disclosure Disclosed is a filter press comprising a substantially cylindrical vessel, a plurality of filter elements disposed in the vessel parallel to one another, and a rotor having a rotor shaft rotatably mounted in the vessel and a plural-ity of rotor elements fixedly connected to the rotor shaft and extending each between two adjacent filter elements, the surfaces of the rotor elements being adapted to be forced towards the filter elements for mechanically compressing filter cakes accumulated thereon, wherein the axis of the vessel is disposed in an upright position, the filter elements and rotor elements being formed as cylinddrical wall members disposed in concentric relationship to one another with the rotor elements extending into the spaces between adjacent filter elements and being secured to a mounting structure connected to the rotor shaft, while the filter elements are supported on a carrier grid in the vessel. The lower ends of the rotor elements can be lowered to an advanced position in which they close the lower end of the sludge space between the respective  rotor element and the associated filter element. In this position the filter press can be operated to expand press diaphragms secured on the rotor elements for mechanically compressing and squeezing the filter cakes accumulated on the filter elements. In the retracted or raised position, the lower ends of the rotor elements define respective passages between themselves and the lower ends of the filter elements for permitting the compressed filter cakes to be discharged therethrough by means of scrapers secured to the radial mounting structure. The invention enables a greater filter surface area to be accommodated in a vessel of a given volume as compared to the capacity of a rotor filter press with disc-shaped filter and rotor elements.

Title: Apparatus and method for very high data rate-compression incorporating lossless data compression and expansion
Inventor: GIBSON DEAN K

Abstract: APPARATUS AND METHOD FOR VERY HIGH DATA RATE-COMPRESSION  INCORPORATING LOSSLESS DATA COMPRESSION AND EXPANSION                            ABSTRACT         A method and apparatus for compressing digital data that is represented as a sequence of characters drawn from an alphabet. An input data block is processed into an output data block composed of sections of variable length. Unlike most prior art methods which emphasize the creation of a dictionary comprised of a tree with nodes or a set of strings, the present invention creates its own pointers from the sequence characters previously processed and emphasizes the highest priority on maximizing the data rate-compression factor product. The use of previously input data acting as the dictionary combined with the use of a hashing algorithm to find candidates for string matches and the absence of a traditional string matching table and associated search time allows the compressor to very quickly process the input data block. Therefore, the result is a high data rate-compression factor product achieved due to the absence of any string storage table and matches being tested only against one string.
