Title: Data streaming using stored control data
Inventor: ROOS JOACHIM
IPC: H04L65/60
Filed: 2007-05-08
Abstract: A data streaming device (1), which transmits payload data to media devices (11) over a network (2), stores TV channel payload data flows DC1-6 from distributor (8) in memory portions MC1-6 (7) in order to allow "trick" play modes (eg. fast forward) without causing delays in the normal viewing mode. During reception of a payload data flow (eg. DC1 in fig. 3a), identification data groups (ie. full data frames IF1-IF7) are detected (4, fig. 2) and for each of these (eg. IF4 in fig. 3b) a corresponding control data portion (1051, fig. 5c) is created (6) and stored (7) before the next (1052, fig. 5c) is created. This allows the first control data portion, governing normal (1X, fig. 5c) or reverse (RW1-3) viewing modes, to be provided without delay while the second control portion, for fast forward modes (FW1-3) which cause more I-frames to be "skipped", follows later. The method also requires only one memory-read operation for each payload data subset and its related control data, and uses only "relative" locations to identify such subsets instead of a "global" reference such as a counter or transport flow number.

Title: Aircraft ejection seat with adjustable headrest
Inventor: MASTROLIA BRAD
IPC: B64D25/10
Filed: 2007-06-01
Abstract: An aircraft ejection seat 10 includes a frame 12 and a headrest 18. The vertical position of the seat is adjusted by a pair of motor driven lead screws 22 24 that cooperate with threaded barrel nuts 26 28 attached to the seat frame 12. The upper end of one of these motor driven lead screws 24 drives a slip coupling 30 driving a splined shaft 34. The splined shaft 34 then drives a gearbox 36 mounted to the seat frame 12. The gearbox in turn drives an upper lead screw 40, which acts on an upper barrel nut 42 to move the headrest 18 up and down relative to the seat frame 12. The upper lead screw 40 is driven in the opposite direction from the lower lead screws 22 24. Consequently, as the seat moves up to accommodate a shorter pilot, the headrest moves down to accommodate the shorter torso of the shorter pilot.

Title: Lubricant composition comprising phosphorus compounds
Inventor: LOPER JOHN T
IPC: C10M137/00
Filed: 2007-11-14
Abstract: A lubricant composition having improved phosphorus retention when the oil is used, has the advantage of decreasing catalyst deactivation in a catalytic system for an engine exhaust, by preventing phosphorus from forming a glaze and masking precious metal catalytic sites. The lubricant composition comprises a base oil and an additive composition that contains a phosphorus-containing additive mixture. The phosphorus-containing additive mixture includes an ash-containing phosphorus compound (e.g. a metal dihydrocarbyl dithiophosphate) and an ash-free phosphorus compound (e.g. a metal-free amine salt of an acid phosphate). A phosphorus retention value provided by the lubricant composition is greater than about 85 percent after oil aging, based on an amount of phosphorus initially present in the lubricant composition.

Title: Resonant discontinuous forward power converter
Inventor: RUSSELL JACQUES
IPC: H02M3/335
Filed: 2007-03-29
Abstract: A discontinuous resonant forward converter comprises a polarity matched transformer 206, a switch such as MOSFET 212, an output rectifier such as diode 220 and a smoothing capacitor 222. Switch controller 210 is configured to control the timing of switch 212 such that current only flows to the smoothing capacitor 222 at node X when switch 212 is on and substantially no current flows during a resonant period when switch 212 is off. A small secondary inductor (fig 5c) may contribute to current limiting and a free-wheel rectifier is not necessary. The length of duty cycle is preferably such that the off period includes half a cycle of sinusoidal resonance to reset transformer 206. The duty cycle or frequency are fixed but also can be controlled in response to inputs of the energy level in transformer 206, the primary voltage, an auxiliary winding (fig 6a) voltage, the current through switch 212 and whether operation in a current limiting mode, a standby power mode or mains ripple rejection is required. During start up the frequency may be increased and the converter operated in a non-resonant mode. Current limiting may be achieved by pulse width modulation. In a standby mode switch pulses may be omitted or skipped. The control circuit can be implemented on a single integrated circuit and provides zero volt switching, improved start up, current limiting and regulation, and alleviates the effects of component tolerances in the resonant circuitry.

Title: Non invasive determination of stroke volume based on incident wave suprasystolic blood pressure amplitude
Inventor: SHARROCK NIGEL E
IPC: A61B5/029
Filed: 2009-05-01
Abstract: A patient's heart stroke volume, or its change over time, is determined from measurement of area 7 above base line 6 and beneath first major peak in signal 1. The signal, or a function thereof, is indicative of varying supra-systolic blood pressure amplitude over time. Preferably the base line is selected at an amplitude passing through initial inflection point 8 in the peak. The signal is obtained from a peripheral artery of the patient with the artery's blood flow occluded, preferably by applying pressure to it, and the signal is preferably obtained from a wideband external pulse (WEP) transducer proximate to the peripheral artery. The artery may be brachial artery 3 and WEP transducer 4 may be positioned beneath the distal edge of blood pressure cuff 2 around the patient's upper arm. The cuff may be inflated to about 25 to 30 mmHg above the patient's systolic blood pressure.

Title: Process for improving alcohol quality
Filed: 1951-04-30
Abstract: The colour characteristics of water-soluble alcohols are improved by intimately contacting the alcohols with sand. Water-soluble alcohols containing 1 to 5 carbon atoms per molecule, and particularly those prepared by the acid catalysed hydration of mono-olefines, are often contaminated with materials giving rise to unpleasant odours.  These alcohols can be deodorised by contacting the alcohol or its aqueous solution with finely divided sand, e.g. river sand, blasting sand, pea gravel and Ottawa sand.  The sand used is preferably not finer than 30-mesh particle size and particle sizes of 4-20 mesh are preferred.  The alcohol may be used in either the liquid or the vapour phase.  If in the liquid phase the alcohol may flow under gravity through a bed of sand or it may be pumped upwards through the bed.  The sand and alcohol may, however, be mixed by agitation and the alcohol subsequently separated.  If in the vapour phase the alcohol is heated above its boiling point and the vapours are percolated through the sand.  Various tables are given showing the effect of different types of sand on isopropanol and ethanol.
