Title: Method and apparatus for measuring duration of froth of beer
Inventor: FUKUHARA TAKESHI
IPC: C12C7/00
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To eliminate fluctuation in the measurements due to difference between individuals Or measuring conditions by providing means for turning an on/off valve on/off requlatively, means for controlling the operation thereof, etc., thereby eliminating intricate operation and heavy work. SOLUTION: A funnel 1 is supported inversely on a supporting base 2 and beer is injected. Upon elapse of a predetermined time, a control means 17 operates a switching means 8 to open an on/off valve 3 by a preset opening thus pouring the beer to the outside of tunnel 1. When the froth level lowers and the froth is detected by a first sensor 5, the control means 17 operates the switching means 8 to open the on/off valve 3 by a smaller opening and continues pouring of the beer. When the froth level lowers further and the froth is detected by a second sensor 6, the control means 17 closes the on/off valve 3. At that moment, a measuring means 18 is fed with time measuring information from a time measuring means 16 and weight information from a weighing unit 7.  Beer produced through extinction of froth is poured to the outside of tunnel 1 and the duration of froth is measured based on the measurements of time and weight at that moment.

Title: Paper refeeder
Inventor: MATSUO HIROKAZU
IPC: G03G15/00
Filed: 1987-01-28
Abstract: PURPOSE:To keep even pressing force against a sheet of a paper refeeding roller constant, by installing a push-up mechanism which pushes the sheet up to a home position at the upper stage where the sheet top is detected. CONSTITUTION:Pushing-up of a bottom plate 120 and a paper refeeding roller 170 by a push-up plate 180 is stopped when a projecting piece 176 of an upper frame 176 releases an optical axis if a photosensor SE5 and a motor is turned off by a signal out of this sensor SE5. When sheets in a cassette 110 are refed, these sheets are decreased and their top level comes down, the projecting piece 176a of the upper frame 176 intercepts the optical axis of the photosensor SE5, a motor is started by the signal, the push-up plate 180 moves upward, and a top level of the sheet at the time of paper refeeding is always kept constant. Thus, the top level of the sheet is always kept constant irrespective of sheet storage residual quantity, so that sheet refeeding height at the time of paper refeeding is always maintained in a constant positional relationship to a handling roller 155 or the like.
