Abstract
Abstract Equipment for use in a milking parlor comprises cluster removal means, milk transfer means and sensing means for sensing cessation of milk flow. When milk flow ceases a signal is sent to the cluster removal means to effect cluster removal and a further signal is sent to the milk transfer means to transfer the milk from a receiver to a bulk storage vessel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
69 words
Equipment for use in a milking parlour comprising cluster removal means, milk transfer means and sensing means for sensing cessation of milk flow and for transmitting a signal in response thereto to the cluster removal means and to the milk transfer means whereby cluster removal is effected, in use, on cessation of milk flow and transfer of milk from a receiver to a bulk storage vessel is then obtained.
Claim 2
Dependent Claim
69 words
Equipment for use in a milking parlour comprising cluster removal means, milk transfer means and sensing means for sensing cessation of milk flow and for transmitting a signal in response thereto to the cluster removal means and to the milk transfer means whereby cluster removal is effected, in use, on cessation of milk flow and transfer of milk from a receiver to a bulk storage vessel is then obtained.
Claim 3
Dependent Claim
61 words
Equipment according to claim 1, wherein the receiver is connected to the bulk storage vessel by a conduit having a flexible wall portion, said conduit being connected to suction means arranged to induce flow of milk from the receiver to the storage vessel and clamping means being provided which act on said flexible conduit to effect controlled opening and closing thereof.
Claim 4
Dependent Claim
49 words
Equipment according to claim 2, wherein control means are provided which, after opening of the conduit by release of the clamp means, reactuates the clamp means to close the conduit after a predetermined time interval the length of which is sufficient to allow emptying of a completely filled receiver.
Claim 5
Dependent Claim
78 words
Equipment according to claim 2, wherein cluster removal is effected by the application of tension to a cord attached to the cluster, the arrangement being such that, on completion of milking, the receiver and cluster are disconnected from the suction means allowing the cluster to be pulled gently from the cow and left suspended in a position in which it is readily accessible to enable the dairyman to fit the cluster to the next cow to be milked.
Claim 6
Dependent Claim
63 words
In or for equipment for use in a milking parlour, sensing means for sensing each pulse of the flow of milk and developing corresponding signal pulses, means for integrating the signal pulses, a leakage path for the integrating pulses and switching means operative after cessation of milk flow and as a result of signal decay through the leakage path to effect cluster removal.
Claim 7
Dependent Claim
63 words
In or for equipment for use in a milking parlour, sensing means for sensing each pulse of the flow of milk and developing corresponding signal pulses, means for integrating the signal pulses, a leakage path for the integrating pulses and switching means operative after cessation of milk flow and as a result of signal decay through the leakage path to effect cluster removal.
Claim 8
Dependent Claim
62 words
Sensing means for detecting the pulse flow of liquid in a conduit, comprising a sensing member adapted to be displaced by each pulse of the flow of liquid in the conduit to produce a respective control signal for each liquid flow pulse, a capacitor connected to receive said control signals, and a resistor connected to provide a leakage path for said capacitor.
Claim 9
Dependent Claim
62 words
Sensing means for detecting the pulse flow of liquid in a conduit, comprising a sensing member adapted to be displaced by each pulse of the flow of liquid in the conduit to produce a respective control signal for each liquid flow pulse, a capacitor connected to receive said control signals, and a resistor connected to provide a leakage path for said capacitor.
Claim 10
Dependent Claim
30 words
Sensing means according to claim 6, wherein the sensing member is adapted to open or block the path of an air jet to a receiver to produce said control signals.
Claim 11
Dependent Claim
64 words
Equipment for use in a milking parlour, comprising sensing means for detecting the pulse flow of milk in a conduit, a sensing member adapted to be displaced by each pulse of said flow to produce a respective control signal for each milk flow pulse, a capacitor connected to receive said control signals, and a resistor connected to provide a leakage path for said capacitor.
Claim 12
Dependent Claim
64 words
Equipment for use in a milking parlour, comprising sensing means for detecting the pulse flow of milk in a conduit, a sensing member adapted to be displaced by each pulse of said flow to produce a respective control signal for each milk flow pulse, a capacitor connected to receive said control signals, and a resistor connected to provide a leakage path for said capacitor.
Claim 13
Dependent Claim
20 words
Equipment as claimed in claim 8, and means responsive to signal decay through said leakage path to effect cluster removal.
