Title: Copoll
Inventor: DRAGLA PETER
IPC: A01H1/02
Filed: 1992-07-23
Abstract: ABSTRACT OF THE DISCLOSURE   A method for separating, purifying and storing corn pollen comprising:          - means for separating corn pollen from tassel and plant material - means for purifying corn pollen, free from toxic or other materials injurious on oral, topical or parenteral administration - means for storing corn pollen. Tassels containing pollen from the corn plant are collected and leaves removed. The tassels are stored in semi darkness in a well ventilated place where the temperature does not exceed 45 degrees C. When the anthers reach an absolute moisture content of between 10% and 12% the pollen is matured and ready for separation. The anthers are opened and the corn pollen separated by grinding or milling the tassels in a rotary mill or grinder operating at a speed of not less than 500 revolutions per minute.   The resulting material is screened through screens of successively decreasing mesh size to remove impurities with a final screening through a mesh with openings of a size of not less than 150 micrometers and not more than 200 micrometers. Fine impurities are separated by flotation and hydrolysis in black plastic bags, in a dry, cool place at a constant temperature of 4 degrees C.

Inventor: FEINLAND SEYMOUR
IPC: G07B17/00
Filed: 1992-09-17
Abstract: A scale for fast determination of weights including a platform and a load cell transducer.  Output of the transducer is converted to a digital signal, processed by a low pass digital filter, and weights computed as a function of the sequence of digital signals by means of an algorithm which compares a first estimate of the weight to the break points of a postal rate chart and uses the first estimate if it is not within a predetermined distance of a break point, and otherwise determines a second, more accurate estimate.  The platform and transducers are combined to form a structure which does not have any significant resources below the cut-off frequency of the filter.

Abstract: The method and apparatus operate to complete the following stages:  at the first stage the coating is held at room temperature in the time interval of from 20 s to 1 hour, depending on the type of polymer coating.  At the second  stage  the  coating  is  held  at  an  elevated temperature  under  excessive  pressure,  sufficient  for suppressing  propagation  of  microcracks  in  such  time interval so that at reaching the predetermined protective properties the thermodestruction of the polymer coating does not occur.   At the third stage performed is the cooling  of  the  polymer  coating  to  room  temperature. According to the  invention,  the excessive pressure  is built up at the first stage and maintained at the cooling stage.  The present invention may find application in the manufacture of integrated circuits,  as well as for the formation of thin polymer insulation coatings.

Data marked with common elements can be found by searching for a particular representative Clement in memory (8). Users can create their own elements, program elements with their own desired functionality, and modify existing elements. Elements (12) can also be compounded together so as to cause a combination of tasks to be performed by simply activating one element.
