Abstract: The invention relates to a fifth wheel for the coupling of the tractor of an articulated truck with a track trailer. The inventive fifth wheel comprises a wheel plate, a kingpin (20) with an inner bore and with an outer coupling or engaging surface (30) as well as with connections for linking electric and pneumatic supply lines between the tractor of an articulated truck and the truck trailer. The supply lines of the tractor of an articulated truck lead to a male connector (100) of a supply unit (10) and the supply lines from a female connector (200) in the interior of the kingpin (20) to the designated places on the truck trailer. The parts of the male connector (11-15) and the female connector (21-25) that pertain to the supply lines and that are interlinkable are configured as respective rotation-symmetrical bushes that are fit into each other in pairs. All bushes (11-15, 21-25) are aligned coaxially with respect to one another and with respect to the axis of the kingpin (20). The radially largest bush (11) and the inner bore of the kingpin (20) each have a diameter that is less than half the outer diameter of the coupling or engaging surface (30) of the kingpin (20).

Inventor: ANSLOW PETER J
IPC: H04B10/08
Filed: 2002-10-09
Abstract: The distortion component of an optical signal received from an optical transmission system, such as an all-optical system, subject to noise and amplitude distortion components, can be evaluated by a method that utilises information derived from analysing the bit error ratio (BER) of the signal as a function of a movable threshold. The analysis is performed in high and low bit error ratio areas of the eye diagram used for data one/zero decision making. The intersections with the threshold axis (where BER=0.25) of extrapolations of the high and low bit error ratio values provide variables V1 and V2 which are divided (V1/V2) to obtain an estimate/prediction of the amplitude closure of the eye diagram resulting from amplitude distortion. The analysis is preferably carried out after Q conversion of the BER values. The method can also be extended to provide indications of Q, bit error ratio and optical signal-to-noise ratio within the signal.

Abstract: An engineered perimeter rim board with machined or otherwise-formed modular recessed receptacles receives and secures I-joists and other manufactured joists at pre- designated spaces along the length of the rim board. The rim board provides pre-measured joist securement locations and structural enhancements by "locking" the joists into position. Receptacles machined/cut into the rim board may be of various shapes, such as a rectangular recess with a flat planar back wall, a profiled recess with curved top and bottom compartments, and/or an angled recess wherein two sidewalk converge to create a recess without a back wall for receiving joists at positions other than perpendicular to the rim board. The preferred 90-degree receptacle profile provides an I-joist web receiving slot for additional lateral support to help prevent joists from buckling, twisting or rolling over.

Title: A method for optimizing file table usage
Inventor: LIND JON A
IPC: G06F9/46
Filed: 2003-04-30
Abstract: An operating system directed to using special properties of a common inter- process communications mechanism (IPC), namely UNIX domain socket-pairs or stream- pipes alternatively as a storage medium for file-descriptors of UNIX processes. When a file-descriptor is written into a socket-pair, and closed in the UNIX process, the file remains open, but occupies no space in the process' file-table. The file-descriptor may later be read out of the socket-pair to reestablish it in the file-table, and access it. This property is implemented in an IPC mechanism of UNIX operating system whereby a process such as a dispatcher may manage more connections and processes than its file-table size allow. This provides scalability improvements of the UNIX operating system.

Abstract: An ultrasonic system for measuring the volume of liquid in a container (65) having a lid (73) in which an ultrasonic signal is emitted and received by a sensor subsystem (64) located on the underside of the lid of the ultrasonic system. The ultrasonic system can measure the exact amount of liquid or the level of the liquid held in the container by processing the roundtrip time the ultrasonic signals took to travel from the sensor subsystem to the surface of the liquid where the ultrasonic signals are reflected back to the ultrasonic sensor subsystem. A solid state, three-phase SCR/diode bridge (96) converts a three-phase alternating current (AC) to a direct current (DC) power source for heating the liquid in a boiler subsystem (57) prior to its transport to the contain er. A second, triac controlled heater (86) is powered by a single phase of the three phase power source, and is used to warm and maintain the liquid held within the container at a constant temperature.
