  • Patent number: 7250109
    Abstract: In the backflush filter (10) according to the invention, in which the flushing back of the filter inserts (15) which are received in several filter chambers takes place by means of flushing filtrate loaded by compressed air, the flush valve (35) and the mud drain valve (39) are actuated by a common drive, whereas the valves or the valve bores (45, 46) are dimensioned in such a manner that the flush valve only releases the connection to the filtrate chamber (19?) of the filter inserts (15?) to be flushed back, when the mud drain valve has already at least partially released the connection between the mud chamber (24?) of the affected filter chamber (14?) with a mud outlet (40). By this, it is ensured in a particularly simple manner that at the backflush process the pressure level in the mud chamber has already dropped before the filtrate for the backflush is loaded with compressed air (see FIG. 2).

  • Patent number: 7229058
    Abstract: The present invention relates to an arrangement (1) to support the front end (2A) of a trailer (2) when the aforementioned trailer is parked on board vessels (3) and other vehicles, comprising connecting means (4, 5) for the detachable attachment of the support (1) respectively to a 10 trailer of the kind in question and to a mobile loading vehicle (6).

  • Patent number: 7229356
    Abstract: A boot for a universal joint is constructed by a boot body and a boot adapter. The one end of the boot is fitted on a propeller inner shaft via its one-end fitting portion and the other end of the boot is fitted on the outer race of the universal joint via its other-end fitting portion, thereby substantially covering the universal joint. The foregoing one-end fitting portion has an annular lip portion at its end portion. Passages for flowing air between the inside of the boot and the outside of the boot are formed on the one-end fitting portion and the annular lip portion. The passages are closed by the annular lip portion being expanded in diameter outward by a centrifugal force caused by the high rotation of the propeller inner shaft, thereby preventing splashed water or muddy water from intruding into the boot when air is sucked into the boot.

  • Patent number: 7106196
    Abstract: A RFID device with a surface treatment which interferes with the transmission of RF signals/data between the RFID device and the RF interrogator or reader. A surface treatment of either RF reflective or RF absorptive ink is deposited on a RFID device using an attenuation pattern to fine tune the read range of the RFID device thereby eliminating or reducing the occurrence of accidental or cross reads between nearby RF interrogators or readers. The surface layer may be deposited at the time of printing the labels thereby fixing the attenuation at a known level or the surface treatment may be applied in an on-demand fashion allowing the attenuation level to be varied to an individual requirement.
