Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge (62) formed of combustible material that is transported into a combustion chamber (44) on a strip (64). The propellant charge (62) is ignited by striking a sensitizer portion (90) of the charge at an oblique angle. The ignition member (66) intermixes the sensitizer material (90) with an oxidizer layer (88) of the surface of the propellant charge (62), resulting in combustion of the charge. When ignited, the propellant charge (62) is compressingly interposed between an orifice plate (74) and a movable portion (80) of the combustion chamber. The orifice plate (74) includes a pedestal (78) with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge (67), insuring that ignition gases are forced through the charge (62). An annular C-shaped ring (82) is interposed between the orifice plate (74) and the movable portion (80) of the combustion chamber (44). When the charge (62) is ignited, the resulting gas pressure resiliently expands the annular C-shaped ring (82) and urges opposite axial ends of the C-shaped ring (82) into sealing relationship between the relatively movable components of the combustion chamber. Combustion gases are communicated through orifices (76) in the orifice plate (74) to a cylinder (40) where the gases force movement of a driver (42) which driver strikes and drives a fastener such a nail. The driver (42) is reciprocally movable within the cylinder (40) and is returned to its precombustion position by a gas spring return cylinder (17). The gas return cylinder (17) is mechanically interconnected to the driver (42) and contains a sealed gaseous fluid that is independent of and segregated from fluids in the combustion chamber (44). An assembly (60) for     deaccelerating the driver includes a series of spaced and aligned progressively sized metal cup members (110,112,114) of progressively increasing mass, contact surface area and interface angles.

Abstract: A wall element has a noise attenuating characteristic and is suitable for use as an aircraft cabin interior panel element that is mounted directly on the aircraft fuselage structure. The wall element includes a rigid lightweight composite panel having a core arranged between two cover layers, and an outer layer arranged adjacent and spaced away from one of the cover layers. The core and the cover layers of the composite panel are air permeable in a direction through the thickness of the panel, while the outer layer is non-air-permeable and is relatively soft and flexible. The outer layer is connected to the composite panel preferably only along the perimeter edge thereof. The non-permeable outer layer faces the aircraft cabin space, while the permeable composite panel is mounted on the fuselage structure. With this structure, acoustic vibrations of the fuselage, to which the wall element is attached, are attenuated and do not result in substantial noise radiation from the outer layer into the cabin.

Abstract: A mobile station (106) in a code division multiple access (CDMA) communication system (100) implements scanning of pilot channels on a different frequency by reserving a periodic frame on the forward channel to allow the mobile station (106) to change frequencies and scan for other pilot channels. To preserve some aspects of voice quality, both the base station (102) and mobile station (106) voice encode speech at a maximum of half rate and transmit the information as secondary traffic prior to the frame where the mobile station (106) scans the alternate frequency. To maximize the trade-off between voice quality and frequency of the scan, the base station (102) indicates to the mobile station (106) the period between other frequency scans via messaging.  To ensure compatibility, this method can be negotiated via known service configuration negotiation techniques.

Abstract: The present invention concerns a wood chips analyser. A sample of a load of chips is weighed, and then inserted into the analyser. A sifting drum sifts out any dust present in the sample. The chips are then spread out through the use of a spreader drum and two vibrating trays, which insure that the chips are oriented horizontally. The chips are then fed to a transparent conveyor. A pair of cameras are arranged about the conveyor, one camera facing each surface of the conveyor. The output of the cameras is sent to a controller, which makes a three-dimensional representation of each chip. Once the sample have been analysed, a report is generated according to modifiable criteria. A typical report will indicate the percentage of a category of chips. This information is then used by paper mills to treat the chips accordingly.
