Title: A base station changes a parameter affecting its operation at the start of a repeating measurment period, analyses the affect and selects the optimum value.
Inventor: TURK JOHN
IPC: H04W16/18
Filed: 2009-09-03
Abstract: A network, preferably a telecommunications network, includes a network core 40, a node, preferably a base station, 3 that operates in accordance with a parameter value and is operable to record performance data during a repeating measurement period and means for instructing the node to change the parameter value, wherein the node includes means for implementing the change at a predetermined point in the repeating measurement period, preferably at the beginning of the period. The parameter value may be repeatedly changed between a first and second value and may be changed in a plurality of nodes simultaneously. The network may also comprise means for analysing the performance data during periods in which the parameter has different values and may select the optimum value in dependence upon the analysis.

Title: Wind Turbine Rotor Blade With Undulating Flap Hinge Panel
Inventor: NING YING
IPC: F03D1/06
Filed: 2009-09-09
Abstract: A wind turbine blade comprises an airfoil having a span, a chord and a camber. The blade includes a blade body 16 of e.g. fibre reinforced plastics (FRP) shells 24, 26 supported by webs 28a,b and a flap 18 to vary the effective blade camber. A deformable panel 20, 22 is located by e.g. bonding between the body and flap and has an undulating profile comprising alternating ridges and troughs extending in a first direction e.g. spanwise. The panel is formed of an anisotropic intrinsic stiffness material with maximum stiffness transverse to the first direction e.g. chordwise. The undulations may comprise corrugations, furrows, valleys, slots or sections of removed material and allow greater movement for reduced strain. A non-structural shroud of e.g. rubber material may cover the undulations for aerodynamics, debris and weather protection. The panel may be a multi ply FRP e.g. E-GFRP with a main fiber direction transverse to the first direction.

Title: Hydraulically-actuated friction coupling
IPC: F16D43/284
Filed: 1961-03-20
Abstract: 971,639. Friction clutches. JARMUFEJLESZTESI INTEZET. March 20, 1961 [March 18, 1960], No. 10079/61. Heading F2C. In a spring-released motor-vehicle friction clutch 9a, 9b, which may (Fig. 3, not shown) be arranged in parallel with an hydrodynamic fluid coupling, engagement is effected by the centrifugal pressure of a liquid supplied continuously from a pipe 6 to a pressure space 7 in a cylinder 1 secured to an input shaft 2, and the radial depth of the liquid is controlled by three sets of exhaust apertures 12, 13, 6a, to produce progressive engagement and an independently determined differential between engagement and disengagement speeds. Initially the liquid ring forms to a radial depth 12. Increased input speed first closes, without effect, the openings 13 by centrifugal valves 14, and later generates sufficient centrifugal pressure to cause a piston 3 to apply engaging pressure to the clutch plates 9a, 9b, thus driving an output shaft 11, and at the same time closing the piston apertures 12, whereupon the radial depth of the liquid ring increases to its maximum at the apertures 6a, producing full clutch engagement. On speed decrease the clutch remains engaged under pressure of the full radial depth of liquid until, at a speed which is lower than that of initial engagement and can be independently determined, the centrifugal valves 14 are spring-loaded inwards to open the apertures 13, at which radial depth a clutch release spring 4 disengages the clutch.

The shoot is provided with a pivoted clearing flap, a diameter test, and a further magnet for setting up eddy currents in the coins, thus to vary their trajectories on leaving the shoot as described in Specifications 378,734 and 385,782. A fixed or pivoted magnet opposed to the magnet 7, may be provided opposite a window in the pivoted flap of the shoot.

Title: A process and apparatus for the treatment of powdered products particularly milk product powders

Abstract: 1,071,850. Agglomerating milk powders. ETABLISSEMENTS LAGUILHARRE. March 11, 1965 [March 13, 1964; March 1, 1965], No. 10441/65. Heading A2E. [Also in Division B2] The agglomeration of powered products, particularly skim milk powder, is effected by producing a stream of the powder and at least one stream of a humidifying fluid, which streams are substantially in parallel and coaxial relation, and a stream of drying air, which stream is substantially parallel to and coaxial with the first two streams and surrounds them, rapidly contacting these different streams to achieve the humidification of the powder and immediate subsequent drying thereof, and then separating the dried agglomerated powder from the air. The stream of powder may be produced by mechanical feeding or by suspension in a carrying air stream. The powder may be supplied directly from a spray-drying process, such as that described and claimed in Specification No. 1,044,501. Powder conveyed at a velocity of 30-60 metres per second by an air flow (10 Kilograms powder per cubic metre of air) through a nozzle 1, Fig. 3, is humidified by steam, hot moisture-laden air, or a mixture of air and steam, passed at a velocity of 50-200 metres per second through nozzle 2, is conditioned as to its temperature and humidity by conditioning air passed through nozzle 23 and is dried by hot air at 140C. passed at a flow rate of 1500-2000 cubic metres per hour through nozzle 3. There may be two streams of steam &c., one located in the axis of the stream of powder and the other around the stream of powder (Fig. 5, not shown). Alternatively, a finely atomized aqueous liquid, such as water, or an aqueous solution or suspension of e.g. the same product as the powder to be agglomerated, may be employed, being delivered to within a stream of the powder travelling at 100-250 metres per second (Fig. 4, not shown). A vertical flow motion is imparted to the air stream which is charged with the powder, by introducing the powder tangentially into a cylindro-conical chamber for entrainment by the flowing air. The agglomerates are collected in a cyclone separator, and are then dried, cooled and graded on a vibratory refrigerating table; the finest particles are re-cycled.
