Title: Device utilizing fluid for effecting nested alignment of articles having a circular cross-section
Inventor: VANDERMEER RICHARD H
IPC: B65G47/08
Filed: 1992-07-09
Abstract: A device is disclosed that utilizes a fluid (normally air) to effect nested alignment of articles having a circular cross-section (such as cans used to package beverages and the like). A conveying section that includes a dead plate and a fluid conveyor provides articles in a mass flow to an aligning section having guides therein spaced a sufficient distance to form guideways through which articles are fluid driven in single file toward a discharge end having an adjacently positioned staging section that also includes a fluid conveyor. The guides, other than a center guide, have first and second portions that are angled with respect to one another, and fluid injected into the sections through apertures in a base plate providing section bottoms urges the articles into a plurality of adjacent rows of aligned articles at the staging section with the articles of each adjacent row offset from one another to affect nesting of the articles. Readily removable section top units preclude upward movement of the articles, and nested and aligned articles discharged from the staging area are provided to a palletizer or like apparatus.

Abstract: In a data processing device for use in a carrier transmission system in processing a device input signal of a plurality of channels, a single data processing circuit (21) and a multiport RAM (33) are used together with a write and read clock counter (51(1)) in place of a great number of data processing circuits, equal in number to an integral multiple of the number of channels, and a likewise great number of sequential circuits, such as D-type flip-flops.  Through a supply arrangement which is preferably a selector (41) for selectively supplying a test signal to the RAM, a processed output signal is supplied from the data processing circuit to the RAM as a processed input signal for storage as memorized signals according to the channels and for read out as a device output signal.  If desired, additional clock counters (51(2)) to 51(N) are used for read out of the memorized signals as additional device output signals.  The stored test signal may be read out as RAM test output signal, which can be processed by the data processing circuit, supplied through the selector, stored in the RAM, and read out as a processing circuit test output signal.

Inventor: SMITH SIDNEY R
IPC: G01N7/10
Filed: 1992-10-07
Abstract: Abstract of the Disclosure A method for rapidly and accurately determining the threshold and critical capillary pressures of a porous rock sample. A fluid saturating the sample, preferably oil, is withdrawn from the downstream end of the sample at an extremely low rate as a result of the introduction of another fluid, preferably gas, at the upstream end. The other fluid displaces the saturating fluid due to a differential pressure between the upstream and downstream ends of the sample. The differential pressure is created by means which does not require use of back pressure valves, thereby avoiding pressure surges and allowing constant slow withdrawal of the saturating fluid. The threshold and critical capillary pressures may be determined from a trace of the differential pressure.

Title: Moving picture receiving method and apparatus
Inventor: SAITO TAKU
IPC: H04N19/136
Filed: 1993-02-25
Abstract: A method and apparatus are presented for compensating for lost blocks of image data in transmitted signals, for instance television signals. The method involves a series of steps performed in the receiving apparatus alone. The first step is the detection of a lost image data block. Then an average value is calculated for each data block adjacent to the lost data block, and an average value is also calculated for each data block at those same positions in the preceding frame. A difference value between the pair of average values for each of the respective block positions is determined, and compared to a predetermined threshold value. The lost data block is replaced by either the average value of the adjacent data blocks in the same frame or by the corresponding data block in the preceding frame, the choice depending upon the difference values determined.

Title: Information Reproducing Apparatus
Inventor: MAEDA SHIGEMI
IPC: G11B20/14
Filed: 1993-06-11
Abstract: An information reproducing apparatus has: (1) a reference signal generating circuit for generating a first reference signal corresponding to a reproduced signal of main information; (2) a first switching circuit for selecting one of the reproduced signal and the first reference signal; and (3) a controller. The controller, which generates a selection-instructing signal, selects the reproduced signal during reproducing of the main information recorded area, and selects the first reference signal during reproducing of the main information unrecorded area. With this arrangement, when the main information unrecorded area is reproduced, the clock for carrying out the reproducing of main information is synchronized with the first reference signal, which corresponds to the reproduced signal. Thus, when the reproducing area is changed from the main information unrecorded area to the main information recorded area, the synchronizing with the reproduced signal is carried out quickly, thereby improving the reliability of the reproducing process.
