Abstract:
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.
Abstract:
An apparatus for electrostatically charging powder material and supplying it to an applicator for electrostatically applying the powder material to solid dosage forms includes a mixer for mixing a sump of the powder material to electrostatically charge the powder material, the mixer including two substantially parallel elongate mixing shafts having oppositely angled mixing paddles thereon and being arranged to rotate in opposite directions; and a feeder for removing the electrostatically charged powder material from the sump and supplying it to the applicator, and a method for electrostatically charging powder material and supplying it to an applicator for electrostatically applying the powder material to solid dosage forms.
Abstract:
Methods and apparatus enabling a diagnostic test to be carried out on milk flowing in a milk line from an animal being milked, without interrupting the milking process, in which a portion of the milk is diverted through a by-pass in which an extracting means (14) in the form of a vacuum-operable pump and timer acts to separate from the milk flowing in the by-pass a milk sample and to deliver said sample through an associated sampling valve (16) to a testing device (18).
Abstract:
Provided herein is a metered dose inhaler for use with a pressurized aerosol container which is preferably breath-actuated. The metered dose inhaler contains a diaphragm which 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.
Abstract:
A set of two-dimensional layers is determined based on a digital three-dimensional model. An image corresponding to each of the layers is rendered on each of a corresponding number of sheets of at least partially transparent material. The sheets of material are assembled together to produce a three-dimensional structure corresponding to the digital model.

Abstract:
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.
Abstract:
A metered dose aerosol actuator, for use in association with a pressurised medicament container (3) provided with a dispensing metering valve having a valve stem (4), comprising a housing (1) adapted to receive the container (3), a stem block (5), extending upwards from the base of the housing (2) and adapted to engage the valve stem (4) by means of a cavity (6) provided in the stem block (5), the stem block being provided with a spray orifice (9) adapted to be in flow connection with the valve stem (4) and the cavity, a sump (8) extending downwards from the cavity (6), relative to the spray orifice (9), wherein the sump (8) has a smooth, rounded interior surface.

Abstract:
A method for determining the similarity between two or more image sequences, and the application of that method to determining the temporal location of periodic or semi-periodic motion in a sequence of images or video.
