Title: Fluid coupling and fastener capture device
Inventor: BYNUM KURT K
IPC: F16L19/00
Filed: 1992-02-21
Granted: 2004-07-27
Abstract: A new capture device comprising a plurality of axially extending tangs (42) on one (10) of a pair of complementary fittings (10, 14) in a fluid coupling and a polygonal circumferential groove (20) on the other fitting (14) adapted to engage the fangs.  Upon rotational engagement of the fittings the tangs (42) engage the polygonal groove (20) and "ratchet" about the junctures between the flats (22) until the coupling is tight. Although not limited to particular materials, the new capture device is particularly suited to very tough, strong and hard materials such as titanium, stainless steel and Inconel alloy because the effectiveness of the capture device is dependent upon the stiffness of the tangs (42). The new device prevents vibrational disassembly of the complementary fittings without preventing disassembly solely with wrenches. Moreover, the complementary fittings and capture device can be repeatedly assembled and disassembled without any damage to the treads (12) or capture device. A variety of configurations of the capture device are illustrated and applications to a bolt and nut and a hole plug (e.g. turbine engine borescope port) are disclosed.

Title: Cutting nozzle assembly for a postmixed oxy-fuel gas torch
Inventor: BISSONNETTE CLAUDE
IPC: F23D14/54
Filed: 1993-11-23
Granted: 1999-04-20
Abstract: A novel cutting nozzle assembly for a postmixed oxygen-fuel gas torch is disclosed.  The nozzle assembly includes a cylindrical shroud which surrounds and extends away from the gas discharge orifices in the gas discharge end of the cutting nozzle.  The cylindrical shroud has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of the preheat oxygen and the fuel gas to provide a hotter, more compact flame which produces a more parallel-sided cut through metal workpieces.  The cutting tip therefore conserves metal as well as cutting gases.  It also cuts faster than prior art postmixed cutting nozzles.

Abstract: A method and apparatus for increasing the capacity and quality of wireless communication between a plurality of remote users and a base station is disclosed. Using measurements from an array of receiving antennas at the base station, parameters of multiple signals transmitted to the base station from a plurality of users in the same channel are calculated and used to obtain the positions and velocities of the users. The locations and other related signal parameters are used to calculate appropriate spatial demultiplexing strategies, reconstructing the individual transmitted signals from the receiver measurements and reducing interference to acceptable levels. This heretofore unavailable location information is used in solving the hand-off problem. This information is also used to calculate an appropriate spatial multiplexing strategy for simultaneous transmission of signals to users in the same channel. This can be the same as or ditinct from the aforementioned receive channel. In combination, the transmit and receive systems establish multiple full-duplex links in the same channel by directively receiving and transmitting signals at the base stations only. This invention can also be implements at the mobile sites to improve signal quality and to establish point-to-point communication links between multiple mobile users. Furthermore, implementation of both transmit and receive functions at the base station is not required. A receive-only system base station will still improve received signal quality and therefore capacity in addition to mitigating the hand-off problem.

Abstract: An instrument probe (10) contains an improved camera and light source  arrangement. The light source (18) is positioned behind the camera (22) for providing indirect illumination of a passage being inspected by the camera (22) such as the contents of a bore hole (28) or its casing (36). The light source (18) is physically separated from the camera (22) thus providing insulation to the camera (22) from heat produced by the light source (18). The camera housing comprises a quick connect and disconnect latch (60) which allows for the swift changeover of camera components at the distal end of the instrument probe (10). A parabolic reflector (34) at the light source directs light distally to the instrument body (10). A second reflector (58) is located on the camera body to further reflect light towards the walls of the passageways, thereby enhancing the indirect light funneled to the area being inspected by the camera (22).

IPC: G06F3/0488
Filed: 1995-01-24
Granted: 1999-01-26
Abstract: A small, stylus-based keyboard in which the arrangement of the keys is a function of predetermined estimated probabilities of the occurrence of variouspossible sequences of keystrokes. Sequences of keystrokes which are estimated tohave a high likelihood of occurrence result in the associated keys being placed adjacent to one another. In this manner, the ease, speed and accuracy of use of small, stylus-based keyboards may be improved. Multiple keys representing the same character may be provided to increase the likelihood that keys included in high probability sequences will be adjacent. The probability estimates may be determined based on a statistical analysis of a preselected sample of text. In addition, keys may be color-coded for ease of identification and grooves may be cut into the housing between adjacent keys for ease of stylus operation. Lights (e.g., light-emitting-diodes) may also be inserted between adjacent keys or beneath the keys for purposes of word identification or next letter prediction.

Abstract: A process of inerting the coal mine site formed by a coal cutting auger (16) at a coal face (14) to suppress methane/coal dust explosion includes introducing an inert gas to a site downstream of the coal face (14) in a sufficient volume to always replace the volume of coal carried from the coal face (14) by a conveyor (18, 20). The flow of coal by the conveyor (18, 20) is used to form the impetus to move the inert gas. The volume of inert gas is maintained sufficient to inhibit the ingress of oxygen bearing atmospheric air to the coal face (14). A leaky seal (56) may be used at the entrance to the coal face (14). The inert gas may be introduced by a conduit (34) arranged part way in the coal seam to form a separate duct extending in the coal seam to the mined cavity or by a duct (60) formed as in integral part of the coal conveyor (18, 20).
