APPARATUS FOR DETERMINING RESILIENCY OF UDDER QUADRANT TISSUES DURING DRAWING OF TEAT Russian patent published in 2005 - IPC

FIELD: research of muscular activity, in particular, equipment for registering of muscular tissue resiliency.

SUBSTANCE: apparatus has casing positioned onto surface to be measured, vacuum pipeline, measurement sensors located within casing, and registering unit. Casing is formed as bowl-shaped housing connected through collector to vacuum pipeline. Two working tools are arranged in diametrically opposite relation within housing and connected through distributor and collector to vacuum pipeline. Distributor is made single-chambered and is equipped with atmospheric air admission apertures, which are closed by spring-loaded valve. Collector is made in the form of two paired vacuum regulators, each being formed as needle-type valve mounted in casing for regulating spring compression or extension by means of screw pair for restricting access of vacuum gage pressure or atmospheric pressure. Working tools are formed as bellows with base and cover, to which vacuum funnel is attached by means of equal resistance beam with tensometers. Bellows and vacuum funnel cavities are communicating with one another through elastic branch pipe. Each of working tools is furnished with tensometers for measuring displacement of cover with vacuum funnel relative to base. Signals generated by sensors are delivered through tensoamplifier to automatic recorder.

EFFECT: wider range of technical facilities for determining of udder quadrant tissue resiliency during drawing of teats.
