摘要:
A radiant tube heater with a burner assembly, a radiant tube assembly and a combustion air pre-heater; wherein the burner assembly comprises: a burner fuel nozzle; a plenum chamber and a pre-mixer chamber; the plenum chamber having a combustion air inlet; wherein in use: combustion air flows from said plenum chamber through an orifice to said pre-mixer where said air is mixed with burner fuel entering said pre-mixer through said nozzle prior to being combusted at a burner head; said pre-mixer being at least partly located within said radiant tube assembly; and where in use at least part of the combustion air supplied to said plenum is preheated in said air pre-heater using residual sensible heat of the hot combustion gas products of the heater.

The present invention relates generally to the field of ligands for nicotinic acetylcholine receptors (nAChR), activation of nAChRs, and the treatment of disease conditions associated with defective or malfunctioning nicotinic acetylcholine receptors, especially of the brain. Further, this invention relates to novel compounds (indazoles and benzothiazoles), which act as ligands for the α7 nAChR subtype, methods of preparing such compounds, compositions containing such compounds, and methods of use thereof.
摘要:
Biochemical Assay Methods. There is described a method for determining a value that allows the effect that a compound has on a target to be compared with the effect that another compound has on the target, which method comprises adding the compound, at a concentration which continuously varies with time, to a flow of the target. The method can be carried out using a microfluidic system.

摘要:
A method of controlling a system having a microfluidic channel structure in which fluids are able to interact to produce at least one product comprises the steps of: i) providing an automated closed-loop control mechanism to autonomously control at least two conditions in, or of, the channel structures, the control mechanism having:— a sensor for sensing at least one predetermined property of the at least one product, means for varying said conditions, and a controller programmed with an algorithm; ii) setting a range of variation for each of the conditions; iii) setting a stop condition for the algorithm; and iv) loading the system with fluids; whereby the sensor produces a sensor signal representative of the predetermined property, the controller receives the sensor signal and, by means of the algorithm, causes the means to vary the conditions within the set ranges until the stop condition for the algorithm is fulfilled.

摘要:
An indirect heater assembly (10) comprises a radiant tube heater (12) and a fan (14) for generating an air flow over the heater (12). In an preferred embodiment and in another aspect, the radiant tube heater (12) comprises a radiant tube burner, an elongate tube 16 and a spiral tube (23) connected to the elongate tube (16) by a U-shaped tube (25). The spiral tube (23) extends around the elongate tube (16) coaxially thereof.
