Title: Phase difference autofocus
Inventor: NIHO YOJI G
IPC: G01S13/90
Filed: 1992-11-26
Abstract: FAST PHASE DIFFERENCE AUTOFOCUS     ABSTRACT A phase difference autofocus method that only requires one FFT for estimating a phase error in the entire synthetic array radar data The phase difference autofocus method of the present invention automatically and efficiently estimates phase errors from radar signals, allowing a well focused SAR image to be produced. The present method comprises the following steps. First, each range bin is divided into two subar-rays. Next, the two subarrays are complex-conjugate multiplied together to produce a cross spectrum of the two submaps produced by the subarrays. Then, the phases of each cross spectrum are aligned with an accumulated sum of the cross spectrums from previous processed range bins. The phase aligned cross spectrum is then added to the accumulated cross spectrum sum. All range bins are processed to get a final cross spectrum sum. Next, a single FFT is performed on the final cross spectrum sum to produce the cross correlation function. Then, the cross correlation function is magni-tude-detected. Since the location of the peak of the cross correlation function is propor-tional to the phase error, a phase error estimate is obtained. Finally, the phase error correction signal is produced for the entire synthetic array radar data. Since only one FFT is performed during autofocus processing, the method is relatively fast.

Title: Low-fat confectionary material and process for making same
Inventor: FITCH MARK D
IPC: A23G1/04
Filed: 1993-01-28
Abstract: Fat in a confectionery chip is reduced to below about 10% by using a low-fat insoluble, non-gummy food material and small particle sugar (less than 100 microns) in combination with about 13% moisture. The sugar to non-gummy food material ratio must be between 2:1 and 4:1 and the moisture between about 10% to about 15%. Hydrated food ingredients are added to retain at least some of the moisture in the bound state. Other ingredients which may be added to the formulation include syrups, milk solids and starch. The chips can be made by simply blending the dry ingredients and adding the moisture to form a dough in the form of a dry, crumbly paste. The dough is mixed or worked up well and then formed into the desired shape. The shape is then cut into pieces similar to chocolate chips.

Title: Level gravity conveyor
Inventor: HAMMOND THEODORE A
IPC: B65G1/08
Filed: 1992-02-14
Abstract: A conveyor arrangement (21), as associated with a storage rack (11), employs a plurality of individual trolleys or cars (45) supported on sloped runways segments (42) which in turn are supported on a pulsating or cyclically-actuated vertical lifting arrangement (56), with the complete arrangement being supported within a rail (26, 27) having upper edges which function as supporting flanges (33) for the loads. When the lifting device (56) is activated to lift the inclined runways (42) and cars (45) upwardly, the loads (12) are lifted away from the supporting flanges (33), whereby the weight of the loads causes the cars (45) to move downwardly by gravity along the sloped runways (42) whereby the loads are forwardly advanced a small amount, until the loads again contact the support flanges (33). When the cars (45) are lowered due to lowering of the lifting arrangement (56), the cars (45) are biased back to a raised position along the upper end of the runway (42) whereby they are again engaged under the load so as to permit a repeat of the cycle.
