Title: Two-piece plastic container and removable cover
Inventor: SETTY THOMAS J
IPC: B65D43/02
Filed: 1997-03-17
Abstract: A two-piece plastic container and removable cover is provided which is particularly adaptable for containing flowable products. The removable cover comprises a one-piece molded generally circular cover having an annular sealing projection extending generally downwardly in a perpendicular direction from an outer periphery of the cover and an annular locking projection extending generally upwardly in a perpendicular direction from the outer periphery of the cover. The container comprises a one-piece molded cylindrical body having a closed bottom and an open top. Two spaced concentric annular inside and outside projections extend longitudinally upwardly from the open top of the body of the container and define therebetween a cover sealing cavity for receiving the cover sealing projection and cooperating therewith to seal the cover on the container. The outside projection on the container is configured for extending partially around the locking projection on the cover and cooperating therewith to lock the cover on the container. Preferably, an opening device in the form of a finger tab or the like is provided for being gripped and pulled by a user for disengaging at least a portion of the outside projection on the container and the locking projection on the cover for removing the cover from the container.

Title: Vector coding method, encoder using the same and decoder therefor
Inventor: KATAOKA AKITOSHI
IPC: H03M7/02
Filed: 1995-09-29
Abstract: Representative vectors z1i and z2j are selected from codebooks CB1 and CB1, respetively, and multiplied by weighting coefficient vectors w1 and w2 of the same number of dimensions as those of the representative vectors by multipliers 21 and 22, whereby weighted representative vectors z1iw1 and z2jw2 are generated. These weighted representative vectors are vector combined by a combining part 3 into a combined vector y ij, and a combination of the representative vectors is selected by a control part in such a manner as to minimize the distance between the combined vector y ij and an input vector X. The weighting coefficient vectors w1 and w2 each have a maximum component in a different dimension and are selected so that the sum of diagonal matrixes W1 and W2 using components of the weighting coefficient vectors as their diagonal elements becomes a constant multiple of the unit matrix.

Inventor: KOJIMA TOSHIHARU
IPC: H04L27/22
Filed: 1992-12-24
Abstract: Within a differential detection demodulator, a received signal is first quantized by a limiter amplifier and then subjected to frequency conversion by a frequency converter.          The frequency converter circuit converts a frequency of a first 2-level signal using a second 2-level signal having a frequency distinct from the frequency of that first signal, and includes: an exclusive OR element for obtaining a logical exclusive OR element of the first and second signal; running average generator means, coupled to the exclusive OR element, for generating a signal corresponding to k times a running average of an output of the exclusive OR element, k being a positive integer; and hard decision means, coupled to the running average generator means, for converting an output of that running average generator means to a 2-level logical signal.  In response to the output of the frequency converter, a phase comparator outputs a relative phase signal representing the phase shift of the received signal after frequency conversion relative to the phase reference signal.

IPC: A01M7/00
Filed: 1997-07-31
Abstract: A sprayer attachment is designed for mounting upon a swather tractor and includes a central frame with a tank which can be carried upon the front arms of the swather tractor. Two masts each carry a respective one of a pair of booms, each for extending outwardly to a respective side of the tractor for movement with the tractor in a spraying action. Each boom includes an inner section, an outer section and a tip portion. In the folding action the outer section and tip portion are folded about a horizontal axis so as to move to a position overlying the inner section. The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle. The tip portion is also moved to the retracted position during the folding action so that the maximum height of the outer section during folding is reduced to avoid contact with power lines and the like.

Title: Methods for detecting colon cancer from stool samples
Inventor: SHUBER ANTHONY P
IPC: C12Q1/68
Filed: 1996-12-20
Abstract: The present invention provides methods for screening for the presence of a subpopulation of cancerous or precancerous cells in a heterogeneous cellular sample, such as a stool sample. The methods take advantage of the recognition that cellular debris from cancerous and precancerous cells is deposited onto only a longitudinal stripe of stool as the stool is forming in the colon. Accordingly, methods of the invention comprise obtaining a representative sample, such as a cross-sectional sample of stool in order to ensure that any cellular debris that is shed by colonic cells is obtained in the sample.

Title: Flow and congestion control in packet switched networks
Inventor: JOHANSSON PER GUNNAR
IPC: H04L12/56
Filed: 1997-03-14
Abstract: A control system in an ATM system controls flows of data cells and flow control management cells from a number of sources to a destination over connections passing a network element. The flow control management cells are returned from the destination via the network element to the respective sources. The network element is exposed to congestion due to contention between the connections, that necessitates queuing of the connections. The flow control management cells have an explicit rate field for an explicit rate value used to limit a source maximum allowed cell rate to a specific value.  An operating function uses deviations from an available rate value for lower priority cells and from a queue length reference forming a desirable queue length, to calculate a modified explicit rate value as a function of these deviations. This modified explicit rate value is introduced into the explicit rate field of the backward flow control management cells.

Title: Short length tapered extrusion cooking device
Inventor: WENGER LAVON G
IPC: A23L1/00
Filed: 1997-07-02
Abstract: Improved short length extrusion cooking devices (10) are provided which can achieve product throughput and quality characteristics of conventional long-barrel extruders. The short length extruders (10) of the invention include a relatively short barrel (14) having an inlet (18) and an endmost extrusion die (20). An elongated, helically flighted axially, rotatable screw assembly (22) is positioned within the barrel (14) and is coupled to motive means (39, 39a) for rotation of the assembly (22) at a speed of at least about 500 rpm. The device (10) may include an internal, apertured flow-restricting device (60, 102) which defines a mid-barrel choke point for the material being processed. An alternate extruder (120) is configured without a mid-barrel restriction and is designed to operate at essentially atmospheric internal pressure throughout the majority of the length of barrel (122) with a significant pressure rise in the final head (134) adjacent the extrusion die.  Preferably, the barrel (14, 122) has an internal bore of generally frustoconical configuration with an effective length to maximum diameter ratio (L/D) of at least about 6. Novel extrusion processes and products are also provided, using extremely short extrusion barrel retention times to give cooked extrudates having essentially no amino acid or vitamin nutrient losses, and/or dense, highly cooked, low moisture feeds. Twin screw extruders (232, 232a) with and without mid-barrel restriction elements (252-256) can also be provided, and include an internally tapered barrel (237) with correspondingly tapered, flighted, axially rotatable screws (238, 240).
