Title: Communication system employing spectrum reuse on a spherical surface
Inventor: JAN YIH G
IPC: H04W16/08
Filed: 1993-06-11
Abstract: COMMUNICATION  SYSTEM  EMPLOYING  SPECTRUM      REUSE ON A SPHERICAL  SURFACE                     ABSTRACT      Orbiting satellites project footprints on the earth.  Each footprint is divided into cells. Footprints of nearby satellites overlap one another, and the overlap increases as satellites approach a pole from the equator.  The positions of all cells generated by all satellites are simulated at numerous points throughout an orbit.  Cells are marked as being active or inactive to compensate for the overlap at each simulated point.  Channel sets are assigned to cells within a reference footprint, and this assignment is propagated throughout all footprints in the referenced footprint's orbit.  The channel set sequences are propagated to other orbits after taking into account inactive cells located near boundaries between the orbits.  Each satellite stores channel set assignments for its cells at the various points throughout its orbit.  All satellites switch their communication parameters at the same instant in response to the channel set assignments.

Title: Process for preparing calcium sulphate
Inventor: NENCINI PIERGIORGIO
IPC: C01F11/46
Filed: 1993-06-23
Abstract: A simple process for preparing acicular calcium sulphate dehydrate is provided in which a slurry of calcium carbonate containing 100 to 800 grams per litre calcium carbonate is mixed with a solution of sulphuric acid containing 80 to 500 grams per litre sulphuric acid in proportions which produce a calcium sulphate slurry having a pH from 0.5 to 1.5. The process can be used to neutralise by-product sulphuric acid from the preparation of titanium dioxide with crushed limestone. Preferably the calcium sulphate slurry is stirred after formation to reduce the level of unreacted carbonate. The calcium sulphate produced has an aspect ratio of at least 4:1 and has excellent properties for use in paper. The process enables the production of acicular calcium sulphate without employing special crystallisation procedures.

Title: Poultry-handling assembly
Inventor: BERRY PAUL S
IPC: A22B1/00
Filed: 1992-05-13
Abstract: A poultry-handling assembly (10) (figure 6) comprises two endless conveyors (12, 13) arranged side-by-side and adapted to move poultry from a first location (15) to a second location (17). Access means at the first location allows birds to enter the as-sembly (10) one by one e.g. with one foot on one conveyor (12) and the other foot on the other conveyor (l3). Conveyor guide means constrain the conveyors (12, 13) to present an open-bottomed V-shaped trough configuration at the second location, where the legs of the birds will slip between the two conveyors (12, 13) for engagement by a restraint device (19) and subsequent take-up by the shackles of a processing plant shackle line (20). In an alternative embodiment (figure 9), the conveyors (12, 13) are re-placed by two side-by-side conveyors (38, 39) which grip the birds laterally.

Abstract: A differential amplifier circuit including a quadritail circuit and a differential pair of transistors.  The quadritail circuit has a first pair of first and second MOS transistors, a second pair of third and fourth MOS transistors,  and a constant current source for driving the first and second pairs.      The differential pair is composed of fifth and sixth MOS transistors and driven by an output current of the quadritail circuit.  An input voltage is applied between the gates of the first and second transistors and between the gates of the fifth and sixth transistors.  A DC voltage is applied to the common-connected gates of the third and fourth transistors.  An output current is derived from an output end of the differential pair.          The transconductance linearity of the differential amplifier circuit can be improved.

Title: Inspection method using area of interest (aoi) analysis
Inventor: SCHWARTZ NIRA
IPC: G01N21/90
Filed: 1994-01-28
Abstract: A technique for detecting defects in stationary products or in products moving on a production line (102, FIG 1) by analyzing area of interest (AOIs) of their modified images uses a matrix or linescan camera (104, FIG 1) for taking images of products (102). The product's dimensions are measured with accuracy, and the existence and alignment of caps and seals is determined. The technique is much faster and more accurate than current techniques and is based up on an analysis of the AOIs and their discontinuities. (209 FIG 1). Carefully selected AOIs of the modified image (2 to 8, FIG 2) are saved in the memory of a computer (106, FIG 1). The method also includes loading look-up tables to modify the gray levels of the products; saving AOIs in memory to be analyzed (FIG 1); analyzing AOI data, counting pixel discontinuities, etc. The results can be used to measure product ovality, check caps and seals on products, and check changes of fluid or content levels in containers.

Title: Method of controlling access to a buffer as well as apparatus for temporarily storing data packets and exchange with such apparatus
Inventor: WIPPENBECK MATTHIAS
IPC: H04L12/70
Filed: 1994-07-12
Abstract: ABSTRACT OF THE DISCLOSURE       Data packets (D1, D2) each assigned to one of at least two priority classes (P1, P2) are stored in a buffer (MEM2) designed to hold data on a threshold value for each priority class wherein, instead of having the threshold fixed for each priority class whereby the data packets of the corresponding priority class will no longer be written into the buffer (MEM2) when the threshold is exceeded ("partial buffer sharing"), one or more thresholds are dynamically controlled.  The current loss probability of the highest priority class (P1) is determined, and the threshold (MEM1) of the lowest priority class (P2) is then raised or lowered (REG1). This results in improved buffer utilization in applications which require a given loss probability for high priority classes, and calculation of a threshold value is no longer necessary.
