Abstract

Abstract A milking system is provided in which an electrodeless conductivity meter continuously monitors milk from each cow and sensed data from each of the meters determines when milking is complete and screens for abnormal milk. The meter may be incorporated in a system to sequentially activate various relays and timers connected to automatic stall gates, washers, feeders, etc., to thereby reduce to a minimum man-time normally required during milking procedures.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 120 words
In a milking system means for controlling power to a milking machine including a milking claw and teat cups and milking machine teat cup detacher and detection of abnormal milk comprising an electrically insulating conduit forming a closed loop, milk inlet and outlet conduits for said loop, said inlet and said outlet conduits being positioned at remote zones of said loop, a pair of transformer cores about said loop and in spacedapart relation, a separate winding on each of said cores, an alternating current power supply connected to one of the core windings, a measuring instrument connected to the other of said windings, and milk flow control means responsive to said measuring instrument and operatively connected to said milkiNg machine.
Claim 2
Dependent Claim 120 words
In a milking system means for controlling power to a milking machine including a milking claw and teat cups and milking machine teat cup detacher and detection of abnormal milk comprising an electrically insulating conduit forming a closed loop, milk inlet and outlet conduits for said loop, said inlet and said outlet conduits being positioned at remote zones of said loop, a pair of transformer cores about said loop and in spacedapart relation, a separate winding on each of said cores, an alternating current power supply connected to one of the core windings, a measuring instrument connected to the other of said windings, and milk flow control means responsive to said measuring instrument and operatively connected to said milkiNg machine.
Claim 3
Dependent Claim 34 words
The milking system as defined in claim 1 including a flow constriction in said outlet conduit and loop bypass conduit means connecting the inlet conduit and the outlet conduit downstream of the flow construction.
Claim 4
Dependent Claim 43 words
The invention defined in claim 1 wherein the said flow control means includes a pair of electrically actuated relays one of which is responsive to a voltage below a predetermined level and the other being responsive to a voltage above a predetermined level.
Claim 5
Dependent Claim 36 words
The invention defined in claim 2 including a time delay relay between said flow control means and said measuring instrument whereby said flow control means are not energized during a first portion of the milking cycle.
Claim 6
Dependent Claim 39 words
The invention defined in the preceding claim wherein the time delay relay is electrically connected to further relays for actuation of automatic stall gates, teat washers, feeders and the like to thereby reduce mantime normally required during milking procedures.
