Title: Scraper arm preferably for use in a silo
Inventor: AHLUND T
IPC: B65G65/40
Filed: 1981-08-03
Abstract: The present invention refers to a scraper arm 7, preferably for the handling of a solid fuel stored in a silo, whereby the arm comprises a primary indicator 8 mounted to rotate in bearings. Serious problems arise when handling, in particular, wood chips since the chips have a high internal friction. If, in addition, the level of the material in the silo is high, extremely large forces are required in order to move the scraper arm. The present invention is characterised in that the arm comprises a primary indicator 8 and a secondary indicator 10, whereby the secondary indicator 10 is attached to the primary indicator 8 in the region of its free end such that it can rotate. The arm also displays a means of applying to the secondary indicator 10 a return force when it has been rotated from its normal position. <IMAGE>

Title: Plant for controlling critical fractions in mineral grinding - using autogenous, grinding, circuit with primary mill having fractioning equipment
Inventor: MARKLUND OLLE
IPC: B02C17/00
Filed: 1988-09-27
Abstract: Before reaching the primary mill, the mineral material is divided into rough and finer fractions, and the finer fractions are then further reduced to a state where they contain critical and subcritical fractions. They are then fed together with the rough fractions to the primary mill. To reduce the problem with critical material fractions, they are made to re-circulate (11) to the primary mill (1) over a flow or quantity measurer (12) for recording the factual re-circulating material amt. The recorded value is compared with a theoretical value for circulating amts. for control of a crusher (5) so that the circulation amt. is maintained at a level equal to that of the theoretical value.

Title: System and method for identifying genuine base stations that serve rogue base stations
Filed: 2015-10-29
Abstract: Methods and systems for determining the identity of a genuine Base Station (BS) that serves a rogue BS, i.e., the genuine BS used by the rogue BS to exchange the communication between the solicited terminal and the cellular network. The ability to identify rogue-serving BSs is a valuable tool in combatting rogue BSs. For example, the rogue BS will often be located in close proximity to the rogue-serving BS, at least in closer proximity than other genuine BSs. Identifying the rogue-serving BS may therefore assist in locating the rogue BS. Additionally or alternatively, identifying the rogue-serving BS may assist in interfering with the operation of the rogue BS, and/or obtaining information regarding wireless terminals solicited by the rogue BS.
