| 20090295105 | TANDEM WHEEL SUSPENSION SYSTEMS - A trailer tandem wheel suspension system comprising a pair of suspension units ( | 12-03-2009 |
| 20100101156 | BARRIER SYSTEM - A mobile barrier system comprises a wheeled trailer and a barrier mounted on the trailer. The barrier comprises a series of panels configured to form walls of the trailer in a collapsed condition for transportation of the barrier. The panels are movable to an erected condition for assembly of the barrier in which the panels are substantially aligned to form the barrier. One or more panels may be adjustable to vary the width of the barrier and two or more barrier systems may be linked to form a wider barrier. Stabilisers are provided to resist movement of the barrier in the erected condition. Guard panels at the top of the barrier can be deployed to resist scaling of the barrier by individuals and/or to increase the height of the barrier. | 04-29-2010 |

| 20100065050 | MEDICAMENT DISPENSING DEVICE WITH A MULTIMATERIAL DIAPHRAGM BOUNDING A PNEUMATIC FORCE CHAMBER - A metered dose inhaler for use with a pressurized aerosol container which is preferably breath-actuated. A preload is applied to the internal aerosol valve by an amount sufficient to result in a dose release, but this is prevented by the application of a pneumatic resisting force. The inhaler comprises a release device which, upon actuation, releases the resisting force and allows the preload to actuate the aerosol valve. A metered dose of medicament is then released for inhalation by the patient. The pneumatic resisting force is established by a negative pressure region defined in part by a diaphragm. The diaphragm includes a central disk of a first, relatively high stiffness material and a peripheral ring, coupled by a flexure of a second, relatively low stiffness material. | 03-18-2010 |
| 20100147293 | AEROSOL ACTUATOR - A metered dose aerosol actuator, for use in association with a pressurized medicament container provided with a dispensing metering valve having a valve stem, including a housing adapted to receive the container, a stem block extending upwards from the base of the housing and adapted to engage the valve stem by means of a cavity provided in the stem block, the stem block being provided with a spray orifice adapted to be in flow connection with the valve stem and the cavity, a sump extending downwards from the cavity relative to the spray orifice, wherein the sump has a smooth, rounded interior surface. | 06-17-2010 |

| 20120109580 | SENSOR BASED MEANS OF MONITORING THE MECHANICAL CONDITION OF ROTATING MACHINERY THAT OPERATES INTERMITTENTLY - A method of monitoring the mechanical condition of a machine in which statistically significant measurements on a characteristic signal are made over a period of time which can include interruptions and variations in the operation of the machine giving rise to uncharacteristic signals and the processing of the signal during the statistically significant measurement automatically excludes those parts of the signal associated with interruptions and variations in the operation of the machine. The invention also includes apparatus for carrying out the above method including a preamplifier, adapted to provide output to a further amplifier, adapted to provided output to dynamic enveloping circuitry, adapted to provide an output to an analogue to digital converter, adapted to provide an output to a digital micro-electronic device. | 05-03-2012 |
