Title: Radial channels in a combination fitting of a flow control valve
Inventor: STATON TIMOTHY
IPC: F04B49/24
Filed: 2002-11-01
Abstract: A flow control combination fitting 10, such as in a piston (20, figure 1) spool valve arrangement for regulating the flow of fluid pressure in an automobile power steering system, comprises a generally cylindrical member 32 having an axial passageway or bore 34 for communicating hydraulic fluid between first a pump outlet and the power steering apparatus. At one end 36 of the fitting 10, a number of channels 38 extend radially from the bore 34 to reduce fluctuations in fluid flow at higher engine speeds and give uniform fluid flow and stabilization of fluid forces on an adjacent piston (20).

Title: Axially extended downhole seismic source
Inventor: BIRCHAK JAMES ROBERT
IPC: G01V1/133
Filed: 2001-05-02
Abstract: An axially extended downhole seismic source is disclosed. In one embodiment, the seismic source includes multiple pressure storage chambers, each having an inlet valve and an outlet valve. The inlet valve is coupled between the pressure storage chamber and the interior of the drill string (8), and the outlet valve is similarly coupled between the pressure storage chamber and the annular space (20) around the drill string. The use of multiple pressure storage chambers allows the pressure front from the seismic source to be extended axially to advantageously increase the fraction of seismic energy transmitted into the formation while preventing damage to the formation.

Title: Electrical generator capacitor
Inventor: WAITT PAUL
IPC: H01G7/00
Filed: 2003-01-18
Abstract: The invention relates to an electrical generator. The generator comprises a capacitor 1 formed from a capacitor plate to store static charge, a semi-conductive capacitor plate whose conductivity varies in the presence of light, heat, or pressure, and a dielectric between the two plates. Means are provided to increase the conductivity of the semi-conductive capacitor plate to increase the capacitance of the capacitor 1. Means such as voltage source V1, switch 2, diode 3, and resisitor 4, are provided to charge the capacitor from a first voltage source. Means are provided to reduce the conductivity of the semi-conductive capacitor plate to increase the voltage across the plates to a second voltage level. Means, such as switch 5, capacitor 6, diode 7 and resistor 8, are provided to discharge the capacitor at said second voltage level to create an energy source V2. In use the capacitor 1 being charged after increasing the conductivity of the semi-conductive capacitor plate, and the conductivity of the semi-conductive capacitor plate is then reduced thus reducing the capacitance thereby increasing the voltage across the capacitor to provide an energy source V2.

Title: Controlling quality thresholds for selecting a modulation and coding scheme
Inventor: TAKEDA DAISUKE
IPC: H04Q7/20
Filed: 2004-01-15
Abstract: In a radio communications system, a modulation and coding scheme (MCS) is selected from a set of MCSs, which are ranked according to transmission rate. An MCS of a higher ranking than the current MCS is selected S14 when communication quality, such as signal-to-interference ratio (SIR), exceeds an upper threshold S13, and an MCS of a lower ranking is selected S16 when the communication quality is less than a lower threshold S15. The upper threshold is controlled S21, S23 based on a first target error rate, such as block error rate (BLER), and the lower threshold is controlled S22, S24 based on a second target error rate different to the first target error rate. Thus, the upper and lower thresholds may be controlled with different step sizes to maximise throughput.

Title: Oil pan structure for an engine
Inventor: OSMAN AZMI
IPC: F01M11/00
Filed: 2004-05-28
Abstract: An oil pan 8 comprises a bottom plate 26, a vertical wall 27 integrally protruded upwardly from outer edges of the bottom plate 26, and an outwardly extending flange 28 formed integral with the vertical wall 27 at the protruded end and fixed to the lower end of a crankcase 2. A pair of bosses 21, 21 are located below the outwardly extending flange 28 and integrally project laterally outwardly from the outside surface of the vertical wall 27 for supporting a engine component 14. A connecting piece 29 is disposed between and integrally connects the two bosses 21, 21. The bottom plate 26, vertical wall 27, outwardly extending flange 28, bosses 21, 21 and connecting piece 29 are all formed by casting. The inner edge 29a of the connecting piece 29 on the side of the vertical wall 27 is formed integrally with the outwardly extending flange 28. Since the connecting piece is not integrated with the vertical wall at its vertical middle portion, strength compromising shrinkage cavities at the inside surface of this wall during casting are thus prevented and the connecting piece need not be reinforced. Also disclosed is an engine comprising a wall and a support member extending from the wall to support an engine component, where the wall and support member are formed by casting.
Patent GB-2399979-A (GB)
Title: Voice-bearing light
Inventor: GRAUMANN DAVID
IPC: H04R29/00
Filed: 2002-12-17
Abstract: The present invention guides a talker into a narrow sensitivity region by providing a light that is only visible when the talker's eyes are just above the sensitivity region of a microphone. When the talker keeps the light within his sight while speaking, there is no wavering problem. If the talker cannot see the light, then he is outside the sensitivity region and is alerted to a potential wavering problem by not seeing the light. In this way, the present invention takes advantage of the fact that the talker's eyes are located in close proximity to his mouth. In addition, high frequencies emanating from the mouth are highly directional and applications with speech input, such as speech recognition, function better when these high frequencies are available for analysis.

Title: Protected swapping of peripheral components and expansion cards by powering on and off a whole computer system according to the position of a retaining latch
Inventor: ORTIZ RICHARD
IPC: G06F1/30
Filed: 2004-10-29
Abstract: Disclosed is a method and system for providing the protected swapping of a peripheral component such as an expansion card. The method makes use of a mechanical retention latch that is attached to the card slot to hold in the card. The latch has an open and a closed position. When the latch is open the power management system prevents the computer from powering up, but when the latch is closed the power management system allows the computer to be powered up. The latch may be coupled to a peripheral component interconnect slot. The position of the latch may be determined by an optical device. The computer may be powered down to a sleep mode when the latch is open and powered up from the sleep when the latch is closed. The system may have a plurality of latches retaining the cards such that if any latch is in the open position the computer is powered down. The latch may automatically close when the card is fully inserted.
