Abstract: A sound reduction unit for a compressor, in which the compressor has a cooling fan and an air intake,  and the  sound  reduction  unit  includes  a housing forming an enclosure about the air inlet and a plurality of sound absorbing baffles disposed in the housing and blocking any direct passage of air into the air inlet. The baffles provide free flow of air, which may be achieved by staggering the baffles in overlapping angular rows in a generally rectangular housing, but which preferably includes allowing a gap between the noise reduction unit and the cooling fan, with  a  flange  baffle  extending  from  the  noise reduction unit beyond the cooling fan.

Title: Uses of nucleic acid analogues in the inhibition of nucleic acid amplification
Inventor: EGHOLM MICHAEL
IPC: C12Q1/68
Filed: 1993-06-07
Granted: 2002-11-05
Abstract: Nucleic acid analogues of the kind described in PCT/EP92/01220 (PNA's) which hybridise strongly to nucleic acids are used to inhibit nucleic acid amplification procedures such as PCR. False positives in subsequent PCR assays are prevented by hybridising a PNA to PCR amplification products. Assays capable of discriminating between single base pair mutants are con-ducted by using a PNA hybridising to one of the two allelic forms to inhibit a PCR amplification of that form selectively. Asym-metric PCR amplifications are carried out by starting a PCR symmetricaly using like quantities of forward and reverse primers and once the amplification is established disabling one primer by hybridising a PNA thereto.

Title: Low friction baler liner
Inventor: DRIGGS LELAND W
IPC: A01F15/12
Filed: 1994-12-09
Granted: 2006-11-14
Abstract: A low friction liner is described for mounting to an agricultural material baler within the discharge chute for the baled materials. The liner includes liner plates of low friction material that are attached by a mount to the inwardly facing surfaces of the baler discharge chute.      The low friction material provides inwardly facing low friction wear surfaces used to engage and guide materials along the discharge chute to a open discharge end. In one preferred embodiment, the low friction surfaces are flat and continuous from forward to rearward ends of the discharge chute plates. In another preferred form, angular indentations are made within the liner with incised or indented shoulders facing the rearward ends of the discharge chute plates to provide abutment surfaces for avoidance of "spring back" of baled materials as they are moved toward the discharge end.

Title: Fluid system for controlling fluid losses during hydrocarbon recovery operations
Inventor: JOHNSON MICHAEL H
IPC: C09K8/90
Filed: 1995-07-04
Granted: 2005-09-06
Abstract: A fluid system has been discovered using a distribution of graded calcium carbonate particle sizes, a biopolymer and a polymerized starch. The biopolymer is a non-ionic polysaccharide of the scleroglucan type. It is important that the calcium carbonate particles be distributed across a wide size range to effectively prevent filtration or fluid loss into the formation. Since the filter cake particles do not invade the well bore due to the action of the biopolymer and starch, no high pressure spike occurs during the removal of the filter cake. This high pressure spike indicates damage to the formation and well bore surface, which damage typically reduces overall permeability of the formation. The rheological properties of the fluid allow it to be used in a number of applications where protection of the original permeable formation is desirable. The applications include, but are not limited to, drilling fracturing and controlling fluid losses during completion operations, such as gravel packing or well bore workovers.
