Abstract: The disclosure relates to a method for silage temperature control in a silo. Measurement transmitters are placed at points where it is desirable to check the temperature of the silage located in the silo. These measurement transmitters are activated, on temperature control, by means of an activation transmitter with an antenna. On activation, the measurement transmitters transmit a signal which is related to the ambient temperature, this signal being received by a receiver. If a measurement transmitter indicates a temperature deviating from a predetermined norm, it is localized by direction finding.

Abstract: An apparatus for discharging loose particulate solid material from a storage space, for instance the hold of a ship. A screw conveyor is suspended in a carriage mounted at the upper part of the space and is horizontally movable. The carriage has a hoisting machinery for wire ropes in which a beam is suspended along which the conveyor is mounted. At least two stabilizing wire ropes are secured to the beam and run to pulleys on the carriage, which pulleys are so disposed that the wire ropes cross each other at a point between the carriage and the beam. From the pulleys stabilizing wire ropes run to a device for keeping the wire ropes tensioned when the beam is raised, lowered and stationary.

Abstract: The disclosure relates to a locking device for an automatic scraper in a centrifuge. The locking device has an automatic safety device in the form of insertable and withdrawable pins which are arranged to prevent unintentional axial movement when the scraper is in an initial position and to prevent unintentonal rotation of the scraper when it is in operative position.
