Title: Non-intrusive flow sensing system
Inventor: BARKHOUDARIAN SARKIS
IPC: G01L11/04
Filed: 1991-08-14
Abstract: ABSTRACT OF THE DISCLOSURE      A nonintrusive flow sensing system and related method are provided for monitoring fluid flow within a conduit, particularly such as a liquid flow.  The sensing system includes an array of ultrasonic transducers mounted on the conduit and adapted to send and receive pulsed ultrasonic signals bidirectionally across the conduit with an upstream-downstream component of direction, and through the conduit in longitudinal and circumferential directions.  Signal transit times are processed to obtain accurate measurements of liquid flow velocity, temperature and pressure.
Patent CA-2109173-A1 (CA)
Inventor: FOX ROBERT E
IPC: A01B63/00
Filed: 1993-10-25
Abstract: A feedback mechanism for providing an implement position signal includes a rotary potentiometer   mounted  on the implement frame adjacent the rockshaft with the axis of the potentiometer shaft extending parallel to the rockshaft.  A linkage structure includes a potentiometer arm connected to a rockshaft arm by a link such that angle the potentiometer arm forms with the link is acute when  the  implement is in the transport position and obtuse when the implement is in the lowered field-working range.  At the lowermost position of the implement, the link and potentiometer arm approach an overcenter position.  The linkage structure provides amplified rotation of the potentiometer shaft relative to the rockshaft when the implement is in the field-working range of positions, while rotation of the shaft is reduced relative to rockshaft rotation when the implement is raised above the field-working position.  In the preferred embodiment,   rotation of the rockshaft 10° in the field-working range results in rotation of over 30° of the potentiometer shaft.  Rotation of the rockshaft 10° in the upper range of raised transport positions results in less than about 8° of potentiometer shaft rotation. The amplified rotation in the field-working range significantly increases accuracy and repeatability of the feedback signal.
