Abstract: A process and apparatus for thermal treatment and stabilization of waste materials in which waste material is introduced into an uppermost first combustion zone of a vertically oriented combustion chamber and a fuel and an oxidant are tangentially injected into the first combustion zone, oxidizing at least a portion of any organic material in the waste materials and melting at least a portion of any inorganic material in the waste materials.  A second portion of fuel and oxidant is injected into a second combustion zone disposed immediately below and in communication with the first combustion zone, melting any remaining inorganic material in the waste material after which the melted waste material is removed from the bottom area of the combustion chamber for disposal.

Abstract: A variable length codeword packer communicates codeword data in successive m-bit bytes. A binary sum is accumulated indicative of a total number of codeword bits received over time. A byte pointer is derived from at least one most significant bit of the binary sum. A bit pointer is derived from a plurality of least significant bits of the binary sum. A first data storage array has a plurality of m-bit first storage bytes and is responsive to the byte pointer for storing received codeword data in the first storage bytes. A second data storage array has a plurality of m-bit second storage bytes and is responsive to the byte and bit pointers for filling the second storage bytes with codeword data from the first data storage array. m-bit bytes of codeword data are output from each filled second storage byte to provide successive m-bit bytes of codeword data. The use of a multistage approach in packing variable length codewords substantially reduces the complexity as compared to single stage designs.

Inventor: LEE KWANG-HEUI
IPC: G11B27/22
Filed: 1992-11-30
Granted: 2001-05-01
Abstract: Disclosed is a circuit for detecting an unrecorded portion in a recording medium, which comprises a window counting portion (10) for receiving an input signal to recognize if the input signal comes from an unrecorded portion of the recording medium and counting a predetermined time to generate a window pulse signal, and a sync signal generator (20) which is enabled by the window pulse signal, in which if the number of pulses of the input signal is not less than a predetermined number, the generator recognizes the current input signal comes from a data region of the recording medium to simultaneously generate a sync signal, while if the number of pulses of the input signal is not more than a predetermined number of pulses, the generator recognizes the current input signal comes from an unrecorded region of the recording medium, not to generate the sync signal. The unrecorded portion is accurately detected not to generate a sync signal due to noise included in the unrecorded portion of the recording medium.

Abstract: An air drying process for a paper machine is disclosed whereby air is impinged directly onto a paper web between top (2, 4, 6, 8) and bottom (1, 3, 5, 7) dryers on an open paper draw. This provides additional  drying and machine speed increases due to improved controlling of the sheet flutter and improved drying via direct air impingement onto the sheet for all paper grades. The structure provides radial jet reattachment nozzles (20, 22, 24, 26, 28, 30) to blow air onto the sheet while the paper web is not in contact with either cylinder surface and the fabric or felt (32).  The nozzle stabilizes and supports the sheet to prevent flutter and bulging.

Abstract: MSM-photodetectors are produced using implanted n-type Si and interdigitated electrodes deposited on the implanted surface. The implantation process decreases the carrier lifetime by several orders of magnitude. By implanting silicon with fluorine or oxygen, the bandwidth is increased relatively to unimplanted MSM photodetectors. Exemplary implanted photodetectors exhibited 3-dB bandwidths which were faster by an order of magnitude compared to their unimplanted counterparts. The detectors are thus compatible with multi-gigabit per second operation and monolithic integration with silicon electronics.

Title: Dripless drive mechanism for caulk dispensing device
Inventor: CHANG PETER J Y
IPC: B05C17/01
Filed: 1995-12-19
Granted: 1999-04-20
Abstract: Simple and economical drive mechanisms for caulk dispensing devices that give a drip-stop release feature to improve control over the bead of caulk. A first embodiment includes a release lever encircling the plunger shaft and extending upwardly therefrom, and an elastic washer encircling the plunger shaft between the housing and release lever for frictional sliding therebetween. The release lever and washer ride forward on the plunger shaft while the trigger is retracted, and when the trigger is released the washer rides backward on the plunger shaft thereby driving the release lever until it engages the plunger shaft to prevent further retraction. In another embodiment, the floating washer and release lever are replaced by a first compression spring that is formed with a forward constricted end having increasingly tighter helical coils to frictionally grip the plunger shaft. Upon retraction of the trigger, the first grip drives the plunger shaft to overcome the friction of the constricted end of the first compression spring and the plunger shaft slides on through. Upon release the first gripping member and compression spring are able to retreat a bit until blocked by the frame. At that point the constricted end of the spring grips the plunger shaft and prevents further retraction, thereby cutting off the flow of caulk and providing a dripless release feature by relieving pressure in the cartridge upon initial release of the trigger.

Abstract: A positioning tool (1) has an elongated cylindrical section (15) for reversibly engaging an acetabular cup (2), which is insertable through a pos-terior opening (28) in the cup. The outer diameter of a proximal portion of the cylindrical section (15) is ex-pandable to engage the inner wall (30b) of the cup in an interference fit to prevent movement of the cup rel-ative to the tool and hold the cup in engagement with the tool to move the cup with movement of tool to place the cup for implanting at a desired po-sition. The expanded portion of the tool may be contracted to release it from the cup after implantation. The proximal portion of the tool compris-ing the cylindrical first section (15) and tapered section (19), which is at-tached to the distal portion and sepa-rated therefrom by a partial transverse slot (22). Third section (15) is di-vided into semicircular sections (34, 35) by a diametrical vertical slot (20) therebetween. Diametrically opposite quadrants (29a, 29b) of the semicircular sections (34, 35) further contain elongated slots (26, 27) therethrough which are perpendicular to the vertical slot (20) and spaced from the edge (57) of the cylinder by a thin section (25). The outer diameter of the proximal portion of the cylindrical third section (15) may be expanded or contracted by pivoting the semicircular sections (34, 35) around the thin spaces (25) between the elongated slots and edges of the proximal portions. The tool further comprises means for causing the semicircular sections to move relative to each other to expand or contract the diameter of the cylindrical section (15).

Granted: 1999-06-22
Abstract: In response to a testing instruction from a PHSC, the cell range of CS 4a is expanded from a range indi-cated by a solid line to another range indicated by a broken line in which CS 4a can communicate with CSs 4b, 4g and 4f as well as other CSs not shown adjacent to CS 4a. Under the control of the PHSC, test calls are successively produced from CS 4a and transmitted to CSs 4b, 4g, 4f and all other adjacent CSs not shown to confirm the normality of connection. Then, in a simi-lar manner as described above, the PHSC repeats this operation successively for all CSs and confirms. the normality of the CSs from obtained results. When an abnormal condition is found out in a test result, the PHSC analogizes from a combination of test routes to specify the abnormal CS.
