摘要:
A pedestal fan (10) comprises a base (16) housing an impeller (64) and a motor (68) for rotating the impeller to create an air flow, an air outlet (14), and a telescopic duct (18) for conveying the air flow to the air outlet.

A humidifying apparatus includes a body and a nozzle detachably mounted on the body. The body includes a chamber, a water tank for supplying water to the chamber, and a motor-driven impeller for generating an air flow over water stored in the chamber. An ultraviolet radiation emitting lamp irradiates water stored in the chamber. The air flow is humidified with water from the chamber, and conveyed to the nozzle for emission from the apparatus. A sensor detects the position of the nozzle relative to the body, and a drive circuit controls the actuation of the lamp depending on an output from the sensor.
摘要:
Described is a fan assembly comprising a body comprising an inlet, an outlet, and means for generating an air flow. The fan assembly also comprises a nozzle mountable on the body for receiving the air flow from the body and for emitting the air flow and a nozzle retaining means for releasably retaining the nozzle on the body. The nozzle retaining means has a first configuration in which the nozzle is retained on the body and a second configuration in which the nozzle is released for removal from the body. The fan assembly also comprises a manually actuable member located on the nozzle for effecting movement of the nozzle retaining means from the first configuration to the second configuration.

The present invention relates to chain extenders, processes for their preparation and their use in the preparation of biocompatible biodegradable polyurethanes and polyurethane ureas for biomedical applications such as stents, scaffolds for tissue engineering. The chain extenders comprise a compound of formula (I)
摘要:
The present invention relates to biocompatible, biodegradable polyurethane/urea polymeric compositions that are capable of in-vivo curing with low heat generation to form materials suitable for use in scaffolds in tissue engineering applications such as bone and cartilage repair. The polymers are desirably flowable and injectable and can support living biological components to aid in the healing process. They may be cured ex-vivo for invasive surgical repair methods, or alternatively utilized for relatively non-invasive surgical repair methods such as by arthroscope. The invention also relates to prepolymers useful in the preparation of the polymeric compositions, and to methods of treatment of damaged tissue using the polymers of the invention.
摘要:
A fan assembly for generating an air flow within a room includes a casing having a plurality of inlet sections and an outlet section for receiving air from the inlet sections. Each inlet section has an air inlet, an impeller and a motor for driving the impeller to draw an air flow through the air inlet section and into the air outlet section. The outlet section has an interior passage for receiving air from the inlet sections and an air outlet. The casing defines a bore about which the interior passage extends and through which a secondary air flow from outside the fan assembly is drawn by the air emitted the air outlet.
