Abstract: A spin chamber for use in an inhaler includes a primary recess to receive air to mix with contents of a capsule. The primary recess has a curved wall. The spin chamber includes a secondary recess to hold a capsule. The secondary recess is located within a bottom surface of the primary recess. The spin chamber includes at least one curved inlet channel to allow air to travel therethrough. The curved inlet channel includes a tangential section and a funnel section. At least a portion of the tangential section is substantially tangential to the curved wall of the primary recess and is connected to an air inlet on an exterior surface of the spin chamber. The funnel section curves toward the primary recess and is connected to an entry point to allow air to enter therethrough into the primary recess.

Abstract: A device configured to generate an air flow, the device including: a compressor; an air flow duct arranged to convey a flow of air generated by the compressor; a gas-filled cavity disposed beside the air flow duct; a wall separating the air flow duct and the cavity, the wall including at least one aperture; and an acoustic resistive screen covering and held in tension over the aperture of the wall. The screen is partially permeable and in fluid contact with air in the air flow duct and gas in the cavity and is configured to attenuate noise transmitted between the duct and the cavity. The resistive screen and the cavity together define a noise-damping resonator.

Abstract: A nozzle for a fan assembly includes an air inlet, a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve includes one or more valve members that are moveable to simultaneously adjust the size of the first air outlet and inversely adjust the size of the second air outlet. The nozzle further includes a third air outlet and a fourth air outlet, the third air outlet being opposite the fourth air outlet, the third and fourth air outlets being oriented in convergent directions.

Abstract: In a compressor, comprising a housing including a flow-through air guiding section with an inlet duct, a wheel chamber formed downstream of the inlet duct for accommodating a compressor wheel, and a spiral duct formed downstream of the wheel chamber, wherein flow slots are formed in a transition region connecting the inlet duct with the wheel chamber, and the transition region extends both in the directions of the inlet duct and of the wheel chamber along a leading edge of the compressor wheel, the flow slots each extend along an axial first length (L1) and along a radial length (RL) with a cross-section (Q), which cross-section (Q) changes over the axial first length (L1) of the flow slots.

Abstract: The yoga asana stand 100 supports a user performing a headstand. The stand comprises an upright member 110, two trapezius muscle support members 120 in the form of flattened bars or legs and a connector member 130. The upright member 110 comprises a rod with a number of holes 112 spaced along part of its longitudinal axis for connecting the support members 120. The holes 112 receive a releaseable connection pin 114 and allow a pivotal connection between the support members 120 and upright member 110, when pin 114 passes through a selected one of the holes 112. The upright member 110 can be relatively rotated from a position being substantially parallel to the support members 120 in a collapsed state, to a substantially vertical position and at an angle to support members 120 in an erected state.
