Abstract: An anaerobic, pasteurizing conditioning system for treating matter such as whole and ground grain and minerals to increase the rate of conversion during digestion and thus the nutritional value thereof. The system comprises a direct fired steam generator adapted for producing treatment fluid comprising steam and non-condensible gases, the gases containing insufficient oxygen for substantial aerobic bacterial growth. The steam and oxygen deficient non-condensible gases are discharged into the vessel for counter-current flow relative to matter passing therethrough. The operation of the direct fired steam generator is controlled for producing a sufficiently large volume of oxygen deficient gases and steam for purging the matter of other gases flowing therewith and maintaining the deficient oxygen level in the non-condensible gases for creating an anaerobic condition. In this manner an improved feedstuff is provided wherein the starch components have first been gelatinized in a heated, anaerobic environment and thereafter fractionated to render the feedstuff more digestible.

Title: Cue signal recording and detection system
Inventor: YOSHIDA YOSHIYUKI
IPC: G11B15/087
Filed: 1990-02-06
Granted: 1995-05-23
Abstract: The present invention relates to a magnetic recording/reproduction device (such as VTRs and DATs).  A cue signal becomes a mark of its position for automatic operation and automatic editing, to be recorded in advance with the contents of the program.  The frequency of the cue signal is selected as to the audio signal band.  On an auxiliary audio track (24) in a  magnetic tape (21), an audio signal as well as a cue signal is recorded in time division manner.  Determination is made of a correct cue signal by providing a mute period before the cue signal recording region and detecting a cue signal by a filter after the detection of a mute period.  The frequency ratio of the cue signal to control signal (CTL) is sought by a counter (6) for a CPU (7) to identify a cue signal in response to the frequency ratio.  By dividing the reproduced signal into blocks, the cue signal is detected from the cycle number distribution of the frequency. The efficiency of the cue signal recording/reproduction can be improved and the structure of detection simplified to carry out precise detection.
