Abstract: A catalyst comprising: (a) a first layer comprising an oxidizing catalyst having an effective PGM loading such that oxidation of hydrocarbons generates sufficient heat to regenerate soot, wherein said effective amount of PGM is greater than about 10 g/ft3; and (b) a second layer adjacent to said first layer and comprising a reducing catalyst to selectively reduce NOx.

Abstract: The present invention relates to the use of a phosphodiesterase 7 (PDE7) inhibitor in the manufacture of a medicament for the treatment of neuropathic pain and to a method of treating neuropathic pain using an inhibitor of PDE7.

Abstract: An integrated circuit has drive circuitry to drive the windings of an electrical motor, means to make a measurement from the drive circuitry during rotation of the motor, suitable for use as motor control feedback, and has an output contact through which the motor control feedback measurement is available as an analog output signal. It can be used with an external motor control circuit coupled to receive the analog output signal to generate motor control signals, to control the drive circuitry. The analog feedback output gives more flexibility to the design of a motor control loop in terms of bit resolution, bandwidth and choice of discrete time or continuous time control.

Abstract: The present invention relates to a novel family of beta sub-unit proteins from a voltage-gated sodium channel, and particularly the human and the rat beta sub-units which have been collectively identified as &bgr;3, in view of their close structural relationship.

Abstract: An exhaust gas catalyst especially for small two-stroke gasoline engines comprises a platinum group metal deposited on a refractory metal honeycomb support and is provided with a diffusion barrier coating which reduces conversion without reducing light-off temperatures. Prolonged catalyst life is shown when exposed to misfire conditions.

Abstract: A centrifuge comprises a rotor which tapers conically downwardly from a maximum diameter upper region to a central bottom opening through which a liquid entry pipe projects upwardly. An outlet end of the entry pipe is shrouded by a concentric cone which is mounted for rotation with the rotor. A flexible diaphragm is secured to the outlet end of the pipe and extends towards the cone so that liquid entering the rotor is directed to flow over an inwardly facing surface of the cone. By this means, the spin of the rotor is transmitted immediately to the liquid. During operation of the centrifuge, rapid changes in the rate of rotation of the rotor are effected so that solids which have separated from liquids in the rotor and have accumulated in the upper region are dislodged therefrom.

Abstract: A method of initiating an operation in dependence on the combined mass of an element and matter which is in or on the element can be used to remove matter which has accumulated on the rotor of a centrifuge. A substantial change is effected in the speed of rotation of the rotor and the rate of change is then measured. The operation is initiated when the rate of change is above or below a predetermined value.
