Title: Hydraulic steering arrangement with a pilot-pressure-operated steering valve
Inventor: GIVERSEN SVEND
IPC: B62D5/09
Filed: 2001-03-06
Abstract: In a hydraulic steering arrangement in which a steering slide valve 2 is controlled by pilot pressures applied to the end faces 8 of the slide from a steering-wheel-operated hydraulic unit 4 or an electro-hydraulic steering unit 6, the highest of the pressures at the four work connections 7 of the two steering units 4, 6 is applied to one end 8 of the slide and the lowest of the pressures acts on the other end 8 of the slide. The selection of the pressures to operate on the ends 8 is by a valve arrangement 11 having shuttle valves 9 and further pressure-controlled two-position valves 13a, 13b. The arrangement reduces the response time of the steering system, ensuring that the highest pressure operates on the slide in opposition to the lowest, usually that of a tank connection, to maximise the pressure differential.

Title: Light load operation of (normally) spark-ignited i.c. engine, eg to facilitate auto-ignition
Inventor: ALLEN JEFFREY
IPC: F01L9/10
Filed: 2001-05-30
Abstract: A method of operating an i.c. engine having a cylindrical combustion chamber 10 and a reciprocating piston 11 involves inducing a central vortex in the combusted gases in the combustion chamber and delivering the fuel and air into the centre of the vortex with the delivered charge being separated from the wall of the combustion chamber by the surrounding swirling combusted gases. This establishes a temperature gradient across the cylinder 12 so that the charge is delivered to the hottest region, facilitating auto-ignition at light loads and better fuel vaporisation for more reliable spark ignition. The vortex may be produced partly by (a) squish lands 54a, 55a, 54b, 55b on the piston and on the hemispherical closed end of the cylinder 12 (b) shrouded exhaust valves (fig.2) and (c) by air-assisted injector 16. The injector 16 may incorporate the spark plug 53. The cylinder may have two intake poppet valves 17, 18 and two exhaust poppet valves 23, 24, each valve being actuated by a respective hydraulic actuator 29-32 controlled by controller 42 in response to signals relating eg to piston position; engine temperature, load and speed and accelerator pedal position. In a multi-cylinder engine, some of the cylinders may be deactivated at low loads to make the remaining cylinders "work harder".

Title: Two-component dispensing gun
Inventor: HURRAY PAUL GREGORY
IPC: B29B7/74
Filed: 2000-03-27
Abstract: A two-component dispensing gun has two longitudinally-extending dispensing passages 26 receiving metering rods 28 and in fluid communication with two straight feed passages 37 adjacent to metering rod tip 29 and valve seats 35 at the exit end of the dispensing passages 26. Valve seats 35 of the dispensing passages 26 extend as protrusions from the gun nose and are sealingly received within cup shaped recesses formed in a detachable nozzle 13 having a static mixer (63, Fig. 15). The nozzle has a back plate (85, Fig. 7) attached to which is a resilient strip of material (92, Fig. 15). The resilient strip flexes out of contact with the openings in the valve seat extensions when the pressure in the liquid flowing through the openings is greater than the pressure of the liquid in the nozzle, and seal the openings when the pressure in the nozzle is greatest. The nozzle has a truncated cone configuration which, in combination with the geometric configuration of the dispensing 26 and feed 37 passages alleviates turbulent flow of the liquid components until reaching the static mixer (63, Fig. 15) within the nozzle 13. A single spring 50 in combination with an inner spring retainer 51 and a yoke crossbar 40 of a trigger 20 assures that movement of the trigger 20 will result in equal movement of both metering rods 28 in dispensing passages 26. A cammed surface of each metering rod 28 in combination with the yoke crossbar 40 provides increased motion of the trigger 20 for fine or slow metering applications.

Title: System for measuring fluorescence and luminescence
Inventor: RUSHBROOKE JOHN GORDON
IPC: G01N21/64
Filed: 2001-01-03
Abstract: An imaging system for measuring luminescence such as chemiluminescence produced by an array of samples such as a microtitre well plate, wherein a presentation plate 12 is located adjacent to the sample plate 10 and presents the ends of a matching fixed array of optical fibres to the array of samples for conveying the luminescence emitted to a CCD camera. Typically the optical fibres are of plastics material having a numerical aperture (NA) greater than 0.2. A second array of silica optical fibres is incorporated for measuring epi-fluorescence. In a preferred arrangement bundles of fibres from each sample are arranged in two sets, a first set which are formed from a non-fluorescing material and a second set which are formed from a material which may fluoresce but enables the fibres formed therefrom to have a higher numerical aperture than those of the first set. One fibre linked to each sample belongs to the one set, and another belongs to the other set. The fibres are arranged interstitially at the input to the camera, so that the light emitted from each fibre falls on a uniquely addressable region of the CCD.
