Abstract: A rotary drag-type drill bit, for drilling holes in subsurface formations, comprises
a bit body having a leading face (96) and a gauge region, a number of blades(98) formed
on the leading face of the bit and extending outwardly away from the axis of the bit so
as to define between the blades fluid channels leading towards junk slots in the gauge
region. Cutting elements (103) are mounted along each blade, and nozzles (104) in the
bit body supply drilling fluid to the leading face of the bit for cleaning and cooling the
cutting elements. At least some of said blades (98) each have a leading edge which is
non-linear, as viewed axially of the bit, as it extends outwardly away from the axis of the
bit. Blades of different shapes may be located alternately around the axis of the bit. The
junk slots at the gauge region, and the kickers between which they are formed, may vary
in width around the periphery of the bit, and may be inclined to the axis of the bit.

Abstract: A metered dose inhaler (10) for use with a pressurized aerosol canister
(18) includes a housing (12) defining a conduit (16) with a mouthpiece (56), and an
actuator (26) with a nozzle discharge orifice (30) arranged to discharge aerosol into
the conduit. An air tube (34) is arranged within the conduit with an inlet (38) of the
air tube formed in the conduit wall (74) and an outlet (36) of the air tube in opposing
relationship with the nozzle orifice. Inhalation through the mouthpiece causes air to
be drawn into the inlet and flow out of the outlet of the air tube to form an air jet
which impinges on an oppositely moving aerosol plume from the orifice. Auxiliary
air inlets (46) in the closed end (24) of the conduit provide a boundary layer flow
along the inner wall (44) of the conduit. Vortex generators (54) on the inner wall of
the conduit add vorticity and turbulence to the boundary layer flow. Automatic
actuation of the canister responsive to the patient's inhalation is achieved by a canister
trigger (154) connected to a movable piston assembly (132) forming a wall of a
variable-volume chamber (162) in fluid communication with a venturi (184) in the air
tube. Air drawn through the venturi by the user's breath causes evacuation of air
from the chamber, thereby moving the piston assembly and trigger to cause actuation
of the canister.

Abstract: An induced current position transducer has a
multi-tap winding. The multi-tap winding allows for
digital interpolation of position to a small fraction of
a wavelength, thereby reducing the amount of analog
interpolation performed by the transducer electronics.
In addition, a multi-tap receiver winding enhances the
total output signal strength, thereby allowing a smaller
receiver winding length along the direction of the
measurement axis. Furthermore, a multi-tap receiver
winding exhibits low impedance, thereby improving the
output signal time constant. The multi-tap receiver
winding of this invention comprises a plurality of
receiver winding loops offset with respect to each other
along the measuring axis, and electrically connected in
series. Preferably, the signal contributions of each
loop combine to form a "vector circle".

Abstract: To form a rigid zone (100) in a composite sandwich panel, to hold a mounting (10) within it, a metal reinforcement plate (200) shaped as a boss is positioned at the required location on the mold surface. The reinforcement plate (200) has projecting studs (201) away from the mold surface. The two heated panel skins (101,103), over each other, are placed in the mold. On closing the mold, internal pressure at 1-3 MPa compresses the overlaid skins with the positioned reinforcement plate (200), anchored to them by the studs (201) with localized compression points. The honeycomb core (102) is between the two skins (101,103). In an Independent claim the mold has an inner core at one wall projecting towards the opposite wall, to pass through the stack of skins and reinforcement plate within the mold, and form a mounting opening. The reinforcement plate (200) has at least one opening (202) through it, which is pierced by a mold core to form the opening in the flanking skins and the core. The plate studs (201) project at right angles, or other angles, from the reinforcement plate surface, at all points. The reinforcement plate (200) is positioned at a moving section of the mold so that, when under pressure, the plate (200) shifts within the mold and the studs (201) lock into the molded panel materials. The studs (201) are pointed, to penetrate through the glass fiber filaments in the panel materials. The two skins (101,103) are composed of a glass fiber fabric embedded in a thermoplastic material, with the warps at right angles to the wefts. The reinforcement plate studs (201) are located for penetration through the glass fiber warps. A second reinforcement plate with a mounting hole can be used, with larger studs than on the first plate (200), to lock into the skin materials in the same way. During molding, the two skins are heated to a molding temp. of 160-200 degrees C. The skins are pierced downwards, to match the reinforcement plate mounting hole, at right angles to their surface planes. The tapered piercing core dimensions can be varied, according to the required size of the mounting hole. The piercing core has a needle structure, with a flat and a curved surface.

Title: Coupleur acoustique
Inventor: SHENNIB ADNAN
IPC: H04R25/00
Filed: 1998-07-07
Abstract: L'invention porte sur un coupleur acoustique se fixant réversiblement à un récepteur, placé au fond du conduit auditif, et consistant en un manchon de couplage cylindrique semi-rigide à parois minces venant se fixer sur le récepteur cylindrique. Un matériau d'obturation adéquat, disposé diamétralement sur le manchon de couplage auquel il s'adapte confortablement, obture le conduit auditif vis à vis des sons. Le manchon de couplage, sensiblement concentrique avec le récepteur, constitue une interface de faibles dimensions et un procédé de remplacement d'utilisation aisée. La fixation au récepteur du coupleur se fait en lui appliquant une poussée axiale minimale qui en assure le verrouillage. Le coupleur reste fermement fixé et peut subir une importante force de traction sans se détacher ni tomber dans le conduit auditif ou en dehors, mais il se déverrouille lorsqu'on lui applique une faible force de rotation par rapport au récepteur. Le peu d'importance des mouvements de rotation lors de la mise en place ou du retrait du coupleur en interdit le déverrouillage accidentel.

Abstract: A general multi-function optical filter for future smart, high density wavelength
division multiplexed (WDM) communication and network system applications using a
Michelson-GT interferometer (MGTI) is invented. MGTI filter is a typical Michelson
interferometer in which one of its reflecting mirrors is replaced by Gires-Tournois
resonator (GTR). One unique feature of this device is that it can function as channel
passing, channel dropping and wide bandpass filters depending on the interferometer
arm length difference. The output of these functions is available in a single port. Other
interesting features of this element are (1) that linewidths of both channel dropping and
channel passing filters are twice as narrow compared with typical Fabry-Perot filter
having similar parameters, (2) that visibility of the output for three functions is always
unity regardless of the mirror reflectance value, and (3) that bandpass filter has an
excellent, near-perfect, box-like response function. Numerical results showing these
characteristics are presented and other applications are discussed.
