A milking arrangement includes a milking module having at least two milking places, a front gate assembly, a sequence gate assembly, an entrance gate, an independent first drive device for moving the front gate assembly between lower and upper positions, and a second drive device for moving the entrance gate between open and closed positions. An independent third drive device moves the sequence gate assembly from a first position to a second elevated position in which the sequence gates are located at a level above and behind animals standing in respective milking places. The sequence gate assembly being configured to move from the second position to the first position such that the sequence gates urge animals standing in their respective milking places to leave the milking places. A control arrangement controls opening of the entrance gate on basis of the position of the sequence gate assembly.

An automatic milking machine controlled by a control unit that, in response to a control request from a first remote user terminal that indicates an intention to initiate transmission of control commands and/or parameter settings, checks whether at least one control command and/or parameter setting from a second remote user terminal has been received within a particular interval preceding a point in time when the control request was received, and if so, returns status data to the first remote user terminal that indicate an identity of the second remote user terminal so that, based thereon, an operator of the first remote user terminal can decide whether or not to remote control the milking machine at the present point in time.

A monitoring system for monitoring a milking point includes an input configured to receive an electrical pulsation signal for controlling pulsation of a pulsator, and a processor configured to identify the occurrence of a milking session based on the electrical pulsation signal received at the input. A signal sensor measures a characteristic of the pulsation signal. The monitoring system may include a connector configured for electrical connection with a solenoid of a pulsator of the milking point. A power harvesting module is configured to harvest power from a flyback voltage generated by the solenoid upon interruption of a current supplied to the solenoid.

A vacuum pump arrangement for a milking plant includes a main vacuum conduit with at least two vacuum pump units for maintaining a system vacuum in the main vacuum conduit. Each of the vacuum pump units includes a pump, a vacuum tank connected to the pump by an intermediate conduit, and an inlet conduit connecting the vacuum tank to the main vacuum conduit. A drainage extends from the vacuum tank and includes a draining valve. The pump sucks air from the main vacuum conduit via the inlet conduit, the vacuum tank and the intermediate conduit. The vacuum pump unit includes a closing valve provided on the inlet conduit and configured to close the inlet conduit in an automatic manner when the pump has been stopped.

A method and apparatus (3) for operating a rotary milking platform (1) to maximise the number of animals milked per unit time. The milking platform (1) is rotated about a central vertical axis (4) by a variable speed motor (6), and comprises a plurality of animal accommodating locations (5) for the animals being milked. An entry position (7) and an exit position (9) accommodate animals to and from the platform (1). A position sensor (10) monitors the angular position of the platform (1). An RFID sensor (12) reads the identity of animals entering the platform (1). Historical data relating to milking time per milking session and the milk yield per animal per session is stored in an electronic memory (17). A microprocessor (15) reads signals from flow meters (14) which monitor the milk flow from milking clusters of each animal accommodating location (5). The microprocessor (15) is configured as each animal enters the platform (1) to compute an optimum angular velocity for the platform (1) in order to maximise the number of animals milked per unit time. The optimum angular velocity is computed as a function of the historical data of each animal on the platform (1), and the current milk yield of each animal on the milking platform (1) determined from the flow meter (14).

A sliding member for a thrust bearing is provided. A sliding layer includes fibrous particles dispersed in a synthetic resin, and has a sliding surface side region and an interface side region. The particles have an average particle size D.sub.sur, first and D.sub.sur, second respectively in first and second cross-sections in the sliding surface side region, and D.sub.int, first and D.sub.int, second respectively in first and second cross-sections in the interface side region. D.sub.sur, first and D.sub.int, second are 5-30 μm, and D.sub.sur, second and D.sub.int, first are 5 to 20% of respectively D.sub.sur, first and D.sub.int, second. A dispersion index of the particles having the major axis length of 20 μm or longer is 5 or more, both in the sliding surface side region in view of the first cross-section and in the interface side region in view of the second cross-section.
