Title: Flooring for poultry pen
Inventor: CHURCH KENNETH S
IPC: A01K31/00
Filed: 1987-05-07
Granted: 1992-01-21
Abstract: "FLOORING FOR POULTRY PEN"            ABSTRACT OF THE DISCLOSURE         Flooring for raising poultry and particularly broiler birds comprises a subfloor in the form of a grid formed by strips at right angles defining openings there-between of the order of four inches across which will support the foot of a person but provides the openings for passage of waste material therethrough.   An upper floor on top of the subfloor is formed of a molded grate or perforated flexible plastic sheet which is supported above the subfloor by vertical flexible pegs which are pressed into openings in the subfloor and are integral with the molded plastics floor.   The pegs are resilient so that on compression by the foot of a person walking on the upper floor, the pegs compress completely so that the person walks effectively on the sub floor.   The birds tend to sit between the pegs rather than on the pegs and thus the flexible flooring cushions around them.

Abstract: ABSTRACT       The present invention relates to a low NOx radiant tube burner.  The radiant tube burner consists of; a primary combustion chamber which is located outside of the furnace and having an injection outlet of the combustion gas located approximately more inside of the furnace than the bung of the  radiant  tube,  a  primary  fuel  nozzle  which  injects primary  fuel  into  the  primary  combustion  chamber,  and  a secondary  fuel nozzle which is surrounded with refractory material and injects secondary fuel  into the radiant tube from   the   area   adjacent   to   the   injection   outlet.          Approximately the  total  amount  of  the  combustion  air  is supplied  into the primary combustion chamber with primary fuel  under  a  high  excess  air  ratio  creating  primary combustion.   The  low concentration of oxygen remaining in the primary combustion gas combined with the secondary fuel creates secondary combustion.

Granted: 1993-08-03
Abstract: Abstract of the Disclosure A component television timing corrector uses edge transitions in the program material of a television signal to determine the time differences between color component signals of the television signal due to the processing of the color component signals along different paths.  One of the color component signal channels is made a reference channel, and the time differences between the edge transitions in the reference channels and in the other color component signal channel is determined.  The time differences are used to delay the other tow color component signal channels with respect to the reference color component signal channel so that the resulting color component signals are in time coincidence.
