Title: Continuous-action filtering method and apparatus
Inventor: KOIVULA TUOMO
IPC: B01D36/02
Filed: 1999-09-29
Abstract: The invention relates to a continuous-action filtering method, a filtering apparatus, as well as to the use of the discussed apparatus as an automatic filter in the fuel or lubrication system of an engine. According to the invention, the apparatus comprises three filtering units (2, 5), having a common inlet channel (7) for a flow to be filtered, a common outlet channel for a filtered flow, as well as a common valve element (9) provided with flow connections (10) for controlling the flow in such a manner that the filtering units are in operation one at a time. An essential feature in the operation of the valve element (9) is its ability to rotate around its axis and, furthermore, its ability to move between two different positions, the two filtering units (2) being operable alternately by rotating the valve element and the third filtering unit (5) being operable by moving the valve. The valve element is constituted e.g. by a cylindrical, axially movable spindle (9), which is also rotatable around its axis. In an automatic filter, the two filtering units (2) can be used for a normal filtering process, wherein, with one of the units in operation at a given time, the other is subjected to a backflush, and the third unit (5) is set in operation as said two units are being serviced.

Abstract: An image special effect of making near objects sharp and far objects unsharp on a screen is readily produced. On a screen (200), an image (156a'') concerning far objects of relative large depth including the background is formed by performing a semitransparency processing of shifting the original image by two pixels upward, an image (154a') concerning middle distant objects is formed by performing a semitransparency processing of shifting the original image by one pixel upward, and an image (152a) concerning near objects is formed without performing any such upward shifting processing. In such an image (222) thus formed, the near image (152a) is sharp, the middle distant image (154a') is a little unsharp, and the far image (156a'') is more unsharp.

Title: Bait station with interior mechanical rodent trap
Inventor: JOHNSON DANIEL C
IPC: A01M23/30
Filed: 2000-07-07
Abstract: An injection molded plastic body has a lid joined by a living hinge. A rodent passageway extends within the body between two aligned holes. The hinge is perpendicular to the passageway, allowing the lid to be opened when the body is fixed adjacent a building wall. The interior of the body is divided by a raised wall which is broken into two segments by an opening to a blind passageway extending perpendicular to the passageway. Two rodent feeding areas are positioned adjacent the blind passageway. Bait blocks are positioned within each feeding area on protrusions which are received within axially extending central holes. The blocks are clamped between underlying rings and cooperating structure depending downwardly from the lid. Instead of bait, a mechanical trap may be positioned on two of three protrusions aligned along the blind passageway. The mechanical trap inter-fits with the protrusions to positively position the mechanical trap.

Inventor: JANTO MARIA
IPC: H04W24/02
Filed: 2000-10-31
Abstract: In a method and device for re-tuning a set of communication channels from respective current frequencies to respective new frequencies, a channel separation value is calculated between the new frequency of each channel and the current frequency of every other channel, an order of re-tuning of the communication channels causing no interference between the new and current frequencies during retune is determined from the calculated channel separation values, and the communication channels are re-tuned in this determined order.  To determine the order or re-tuning of the channels, the calculated channel separation values are compared to a given minimum channel separation value, pairs of new and current frequencies having a calculated channel separation value lower than this given minimum channel separation value are identified from this comparison, an adjacency matrix is built from these identified pairs of new and current frequencies, and a topological sorting algorithm is applied to the adjacency matrix. The present invention further relates to a method of calculating a channel separation value between a first channel frequency and a second channel frequency, and a method of detecting co-channel interference between two communication channels using this method for calculating channel separation values.

IPC: H04L12/58
Filed: 1999-06-02
Abstract: A method is disclosed for sequential transmission of at least two sub-packages for the data package from an electronic communication transmitter to an electronic communication receiver. A first sub-package of the data package is transmitted from the transmitter (figure 2, 204) and includes identifying information pertaining to a second sub-package of the data package (figure 2, 210), with the first sub-package having less data content than that of the second sub-package. The receiver provides the user thereof with the choice of whether to have the second sub-package transmitted by the transmitter.  Transmission instructions are transmitted from the receiver to the transmitter in response to an affirmative selection by the user of the receiver to the choice of whether to have the second sub-package transmitted (figure 2, 214).  The second sub-package is transmitted from the transmitter upon receipt by the transmission instruction from the receiver.

Filed: 1999-12-15
Abstract: The present invention achieves a fast handling of the predicted jumps by introducing an additional buffer (20) for not reported predicted jump instructions in a reorder buffer. This additional buffer (20) is separate fr om the main buffer (10) and is supplied only with information associated with instructions related to predicted jumps. A predicted jump instruction is preferably stored both in the main buffer (10) and the additional buffer (20 ). The additional buffer operates in parallel with the main buffer (10) and is designed as a linear first-in-first-out queue. The first not reported jump i s then always easily available at the top of the queue for evaluating the jump  conditions. If a mispredicted jump is determined, the reorder buffer is flushed by a flush generator unit (42).

Inventor: SABOURIN MARC J
IPC: D21C1/00
Filed: 2000-02-24
Abstract: The main aspect of the present invention is based on introducing process fluid into a compressive pretreatment stage, in an environment of elevated temperature and pressure, thereby initiating lignin dissolution in the chips at a point farther upstream than was previously known. In a preferred implementation of the present invention, this process fluid includes recycled process reagents drawn from process lines farther downstream. In another aspect of the invention, some of this process fluid is extracted as pressate during compression of the chips, and the pressate is reintroduced downstream, into the plant's recovery system. In a particularly effective implementation of the invention, the feed material is delivered under pressure to a compression device which has a variable speed motor such that the duration of exposure of the chips experience an initial processing of consolidation and extraction of fluids through the walls of the compression device into a pressurized collar or flash tank. THereafter the material is further consolidated at a high compression in the ratio of at least 3 to 1 and up to 8 to 1 or more, before discharge. The relative duration of the exposure of the material as between the consolidation phase and the high compression phase, can be pre-established by, for example, the relative screw shaft lengths and wall characteristics defining these regions.
