Abstract: Provided are pharmaceutical compositions and methods for preparing pharmaceutical compositions comprising Ibuprofen using solventless mixing methods. Excess coating material that is not bound to coated Ibuprofen may be removed by a sieving process. Coating and dosing ratios can also be optimized to minimize the amount of excess unbound coating material. Additionally, the compositions can be formulated to preserve the functional coating of coated Ibuprofen and to minimize aeration of Ibuprofen when mixed into suspension.

Abstract: A coupling (1,2) has an inner member (111) and an outer annular member (131) and an intermediate annular member (121) which when aligned share a common axis and have a common centre on the common axis. The inner and the intermediate annular member are constrained to rotate, one with respect to the other about a second axis perpendicular to the common axis. The intermediate annular member and the outer annular member are constrained to rotate, one with respect to the other about a third axis (Z) perpendicular to the common axis (X) and the second axis (Y). The members are spaced apart to leave a gap (103) between each of the members.

Abstract: A constant velocity joint comprising two concentric couplings, a first coupling comprising an inner member, an intermediate annular member and an outer annular member, the members being concentric. The inner member of the second coupling is common to the outer member of the first coupling. The members of the couplings are constrained to rotate one with respect to another and the outer member of the second coupling is constrained to rotate angularly in respect of the common member in a way that is the mirror image of the rotation of the inner member with respect to the common member.

Abstract: A nut for a lead screw comprises two or more concentric annular members which, when aligned, have common axes. One member is contained within another member outside it. A first member has an outer convex spherical periphery and a second member has an inner spherical concave periphery, the peripheries being concentric with the centre, and the inner periphery of the second is engaged with the outer periphery of the first member. The second member is constrained to rotate about the first member on an axis perpendicular to the common axis.

Abstract: A coupling comprises a pair of members: a first member comprising an outer convex spherical periphery centred about a central point and a torsional axis extending through the central point, and a second annular member has an inner concave spherical periphery centred on the central point and complementary to the outer periphery of the inner first member. The spherical surfaces of the inner and outer members co-act to transmit radial loads and loads acting along the common. Axles extend radially of the central point and couples the first and second annular for transmitting torsional load from one to the other. The each of the pair of members is rotatable one relative to the other about the said central point in a direction constrained by the axle arrangement.

Abstract: A bearing block to support and guide movement of a slat support arm forming part of a slat support assembly in which the slat support arm is movable to deploy a slat attached to one end of said slat support arm from a leading edge of an aircraft wing is disclosed. The bearing block comprises a plurality of bearings mountable therein so as to lie in rolling contact with an associated bearing track on a slat support arm extending through the bearing block. Each bearing comprises a bearing element rotatable about a shaft fixed to the bearing block an and is configured so that an axis of rotation of each bearing element angularly adjusts, relative to an axis of the shaft on which it is rotatably mounted, to compensate for misalignment between said shaft and an associated bearing track. A slat support assembly and an aircraft wing is also disclosed.

Abstract: A coupling comprises a plurality of members, including an inner member and an outer member with one or more intermediate members arranged in pairs. One member of a pair constrained to rotate about a single axis relative to a member of the pair outside it, and in which the inner member of the pair is nested within the outer member of a pair. Members are formed as segments of spheres with a common centre point on a torsional axis though the inner member.

Abstract: A method of moulding a component having a closed shape and defining an internal void having a predetermined size and shape is disclosed, together with a core plug for use in the method. The method comprises the steps of: (a) cutting a piece of open cell foam material to substantially match said predetermined size and shape of the internal void of a component to be moulded; (b) applying a flexible sealant to an outer surface of said cut piece of resilient open cell foam to form a closed core; (c) placing said closed core in the mould to support a component during moulding and curing; (d) generating a vacuum within the closed core to collapse it within the void after the moulded component has cured, and (e) removing the collapsed core from the molded component through an opening in said moulded component.

Abstract: A support assembly (1) for guiding a flap (42) on an aircraft wing (41) during deployment of the flap is disclosed. The assembly comprises a guide track (2) defining a two-dimensional path, a cylindrical bearing follower (12) having a longitudinal axis constrained so as to follow said path during flap deployment, a shaft (23) extending from the bearing follower and, a spherical bearing coupling an end of the shaft to the bearing follower such that the bearing follower is rotatable relative to the shaft about the longitudinal axis of the bearing follower as it travels along the track. The spherical bearing also enabling rotation of the shaft about its longitudinal axis relative to the bearing follower and rotation of the shaft about a center point of the spherical bearing such that the flap is fret to move in multiple directions.

Abstract: A motion analysis system (10) in which sensor elements (20) attached to movable body segments record movement parameters including angular velocity and acceleration. A control device (40) receives the movement parameters and determines an overall motion of the movable body segments. The overall motion is analysed against an acceptable motion model to determine whether the overall motion is within acceptable limits. The sensor elements (20) and control device (40) are lightweight and can be worn during normal movement activities thereby allowing monitoring of work-based activities, such as lifting or typing. The invention is useful for detecting and correcting problems leading to lower back disorders and repetitive strain injuries.

Abstract: A cochlear implant system in which information about the periodicity of a received audio signal in each filter channel is used as a factor in determining the rate of stimulation applied to a tonotopically placed electrode corresponding to the relevant filter channel. As such, the stimulation rate for each electrode is related to the periodicity of the signal in the filter channel corresponding to that electrode. This may allow for improved perception of pitch by the implant recipient.
