Patent EP-0395486-A2 (EP)
Inventor: MEUSER WILLIAM E
IPC: C10G1/10
Filed: 1990-04-24
Abstract: A method and apparatus for the thermal conversion of organic waste materials includes a tank having a molten metal bath, preferably lead, through which apertured containers are trans­ported by primary conveyer members in a plane intermediate two arrays of heating devices. Buoyancy of the waste-filled contain­ers is resisted by abutment members within the tank while align­ment elements on the containers prevent the containers from becoming askew during their travel through the tank. The abut­ment members may comprise fixed rails or secondary conveyor members spaced atop the primary conveyor members. Agitation devices within the tank assist in maintaining maximum heat dis­tribution throughout the bath. Produced hydrocarbons are col­lected by a main hood overlying the majority portion of the tank bath surface while separate shroud assemblies overlie other, individual isolated bath surfaces at the entrance and exit of the tank. Inorganic and/or products not converted by the elevated temperature of the bath (over 650 degrees F), accumulate on the surface and are periodically removed by a skimmer apparatus, communicating with the exterior of the hood. A continuous proc­ess is achieved by utilizing conveyors to deliver and retrieve the containers to and from the tank, respectively.

Abstract: An abrasive liquid jet cutting system has a cutting head (14) for directing a jet (17) of ultra high pressure water and grit to a work piece (11). The jet cuts the work piece in a desired pattern to form a product. The liquid from the jet, grit, and particulate materials of the work piece are collected with a receiver (19) located generally below the cutting head (14). Controls (18, 84) for both the cutting head (14) and receiver (19) are coordinated to move the receiver along with the cutting head so that the water and particulate materials are collected by receiver. The receiver (19) has an upright tubular member (37) provided with wear resistant sleeves (49, 53, 57, 58, 59) and an upright central rod (64) to absorb the impact forces of the water and particulate materials that move through the receiver. A drive means (68, 79, 82) connected to the tubular member operates to continuously rotate the tubular member, sleeves and rod to distribute the wear around the sleeves and rod caused by the water, grit and particulate materials that impinge thereon.

Abstract: In order to test data lines of a RAM, a test word is written into all of the address locations of the RAM. The test word is read from all of the address locations of the RAM and a check is made that the test word as read from each of the address locations is the same as the test word written in. The writing, reading and checking operations are then repeated for other test words. The test words are defined as follows. For each value of s from 0 to (n-1), where D is the number of data lines and 2 n  => D > 2 n-1 , there is a first test word which (subject to truncation if necessary to limit the number of bits in the word to D) has groups of 2 s  bits, wherein the bits of each group are of the same binary level and the binary level alternates between groups. Also, for at least one of the values of s from 0 to (n-1), there is a second test word which is the same as the first test word for the same value of s except that the corresponding bits of the two words are of opposite binary level.

Abstract: A method of data compression achieved through run-length encoding is disclosed. The method expands a 256 code point eight bit character set to have additional code points. The additional code points provide for the encoding of identical character runs of less then three characters, by assigning numeric weights corresponding to the non-zero digits necessary to express positive integers within a limited range in a specific radix. The presence of the additional echo code points in a data stream are interpreted to mean echo the last normal character the specified number of times. The echo code points are additive in that, the assignment of numeric weights based on non-zero digits in a specific radix, provides an additive sequence to sum to any desired value in the supported range. Also, permitting the highest value code point to be repeated an arbitrary number of times, removes the run length constraints on the upper bounds of identical characters that can be encoded.

Abstract: A video tape recorder has a tape tensioning mechanism (61) for tensioning a magnetic tape (6) drawn out of a tape cassette (2). The tape tensioning mechanism has a tensioning arm (56) angularly movably mounted on a movable chassis (16) with a tensioning pin (57) for contacting the tape to tension the tape when the tape has been loaded in a predetermined tape path, a tightening lever (65) movably mounted on the movable chassis, and a tension spring (68) for normally urging the tensioning arm in a direction to turn the tensioning arm to bring the tensioning pin into contact with the tape. A pusher (72) is fixedly mounted on a fixed chassis (14) for pushing the tightening lever to tighten the tension spring substantially at the same time that the magnetic tape is loaded in the predetermined tape path. When the magnetic tape is not loaded in the tape path, the tightening lever is released from the pusher to loosen the tension spring. Since the tension spring is not required to bias the tensioning arm when the magnetic tape is unloaded and is only required to bias the tensioning arm when the magnetic tape is loaded, the tension spring may be of a relatively small size.
