Abstract: A rotating platform having a plurality of stalls is provided, each of the stalls being configured to house a respective animal during milking. The stalls are separated from one another by delimiting structures. A camera registers three-dimensional image data of the rotating platform within a field of view. A controller receives the image data that has been registered while the rotating platform completes at least one full revolution around its rotation axis. The controller processes the image data to derive a set of key features of the rotating platform, and then stores the set of key features in a data storage, which is configured to make the set of key features available for use at a later point in time.

Abstract: A system and method for providing a decision basis for controlling a robotic arm to perform at least one action relating to a milk-producing animal, wherein a camera registers three-dimensional image data of a milking location that includes a reference object and a rotating platform upon which an animal stands with its hind legs facing the camera, and a control unit checks if an entry window for a robotic arm can be found in the image data by searching for the reference object in the image data, and if the reference object is found the control unit searches for an acceptable obstacle-free volume in the image data, this volume being located within an allowed space relative to the reference object.

Abstract: A camera registers three-dimensional image data representing a milking location for a milk-producing animal standing with its hind legs facing the camera, where the image data are processed to identify an udder of the animal, and subsequently a tail detection process is applied to the image data to identify a tail of the animal, where upon identification of the tail, the tail is excluded from being regarded as a teat when providing a decision basis for controlling a robotic arm that performs at least one action relating to a milk-producing animal. The tail detection process involves searching for an elongated object extending in a general direction being perpendicular to a floor surface of the rotating platform upon which the animal is standing and at a shorter distance from the camera than any surface element of the identified udder.

Abstract: A supercharger cooling system provides a path for coolant from an air/coolant heat exchanger to a supercharger intercooler and then loops around the supercharger housing proximal to a hot outlet end of the supercharger and back to the heat exchanger. The heat exchanger may be a dedicated air/coolant heat exchanger or be a vehicle radiator. The intercooler is sandwiched between the supercharger and intake manifold and cools the flow of hot compressed air from the supercharger into the intake manifold. The supercharger cooling loop cools the bearings and seals, the forward ends of the male and female rotors, and the male and female rotor gears. The cooling loop is preferably located between the supercharger rotors and the rotor drive gears to form a barrier to heat. A dedicated pump cycles the coolant flow and restrictions control the flow of coolant to the supercharger.

Abstract: A supercharger cooling system provides a path for coolant from an air/coolant heat exchanger to a supercharger intercooler and loops around a hot outlet end of a screw type supercharger and back to the heat exchanger. The heat exchanger may be a dedicated air/coolant heat exchanger or be a vehicle radiator. The intercooler is sandwiched between the supercharger and intake manifold and cools the flow of hot compressed air from the supercharger into the intake manifold. The supercharger cooling loop circles the front rotor bearings thereby cooling the bearings and seals, the forward ends of the male and female rotors, and the male and female rotor gears. The cooling loop is preferably located in the outlet end wall between the supercharger rotors and the rotor drive gears to form a barrier to heat. A dedicated pump cycles the coolant flow and restrictions control the flow of coolant to the supercharger.

Abstract: A pressure equalization system reduces or eliminates a pressure differential across supercharger rotor shaft seals. Under high boost, rotor shaft seals often fail, allowing hot compressed air into an oil lubricated space containing rotor bearings and gears (and vented to ambient pressure), reducing oil lubricating effectiveness and resulting in increased wear and failure. Under low or non boost operation, the pressure differential is reversed causing the lubricating oil to leak into the supercharger interior and accelerated rotor seal wear. The pressure equalization system includes flow restrictive seals on both rotor shafts, separated from the rotor shaft seals by vented spaces, thereby isolating the rotor shaft seals from boost or vacuum in the supercharger interior and reducing or eliminating the pressure differential across the rotor shaft seals. Maintaining close to atmospheric pressure on both sides of the rotor shaft seals during boost and vacuum operation reduces wear and failures.

Abstract: A vibration damped hand held rivet bucking tool having a vibration exposed inertia member (10) provided at a forward end with a rivet engaging implement and a handle (12) insulated from the inertia member (10) by means of two pretensioned coil-type springs (15, 16) which have different diameters and which are located with the small diameter spring (16) inside the large diameter spring (15). A sleeve element (17) connected to the inertia member (10) is located between the springs (15, 16), and a central rod (18) connected to the handle (12) extends into the small diameter spring (16). The large diameter spring (15) acts between a shoulder (23) on the sleeve element (17) and the handle (12), respectively, whereas the small diameter spring (16) acts between an inner shoulder (24) on the sleeve element (17) and an outer shoulder (26) on the central rod (18). A central bore (20) in the inertia member (10 ) accommodates the springs (15, 16) and the sleeve element (17).
