摘要： An infrared radiant heater for use in an infant warmer open care bed. The heater includes a curved reflector within a similarly shaped housing. Between the reflector and casing is at least one baffle made of a heat insulating material. The baffle divides the inside of the housing into a number of separate insulating air gaps. In order to ensure that heat is not conducted through the head, spacers protrude from the housing to support the baffles at their required positions maintaining heat insulating air gaps between the heater head components.

摘要： A laundry washing machine in which the period of each agitation stroke (comprising "ramp", "plateau" and "coast" phases) is controlled by adjusting the "coast" phase of each stroke in order to maintain consistent washing performance. The "coast" phase is initiated (after a predetermined period has elapsed in the "plateau" phase) by starting a timer and allow the motor to coast until the motor velocity drops to a predetermined reversal velocity at which point the motor is reversed to begin the next agitation stroke. The value of the timer when the velocity reaches the reversal velocity is compared to a desired value or range of values. The predetermined value of the reversal velocity is increased if the timer value is greater than the desired value or range of values. Alternately, the value of the reversal velocity is decreased if the timer value is less than the desired value or range of values. The period of the coast phase of the next agitation stroke should then be closer to the desired period.

摘要： An electric motor is suitable for use in, for example, a home appliance, such as a refrigerator/freezer, to drive a fan blade. The electric motor includes a permanent magnet rotor and an excited two part laminated stator. The two parts of the stator are adapted to be connected together about the rotor with the axis of the rotor in the plane of the laminations. The rotor has two axially separated pole regions and the stator is configured to provide a separate rotor receiving pole pair for each rotor pole region. Each stator pole pair provides a rotor receiving space within which respective rotor pole regions are disposed, wherein the stator is made up of separate laminations of ferromagnetic material and adjacent laminations are displaced relative to each other in the plane of the laminations in directions perpendicular to the rotor axis such that the stator poles are each formed by a pair of semi-circular shaped poles to provide the rotor receiving spaces. The stator is constructed from a single piece, with a central portion of the piece being removed and the remaining unitary portion being juxtaposed to form a magnetic circuit having two circular rotor receiving spaces adapted to receive the rotor. A method of constructing the stator for the electric motor from a single piece of laminated magnetically permeable material is also disclosed.

摘要： A laundry machine which includes a method for adaptively controlling the flow of water into the laundry machine during the rinse phases of a wash cycle. Water is admitted into the machine through a proportional valve and the flow rate with the valve set at a predetermined degree of opening is calculated. This is compared with a desired flow rate and the degree of opening of the valve is incremented, decremented or left unaltered, depending on whether the calculated flow rate is less than, greater than or substantially the same as the desired flow rate.

摘要： An infrared gas analyser. The analyser comprises a sample cell located in a gas flow, a source of infrared radiation of selected wavelengths which is propagated through the sample cell and an infrared detector which receives radiation which has passed through the cell, The radiation incident on the detector provides a measure of the concentration of selected substances in the gas flow due to one of the wavelengths being selected to be absorbed by the gas being measured. One preferred use is as a humidity sensor in a medical respiratory circuit where at least one selected wavelength is a wavelength strongly absorbed by water. Heating means am associated with the sample cell to vaporize any liquid water which may enter it and the cell is provided with internal baffles to reduce deposition or condensation of water on internal surfaces through which infrared radiation must pass. In one embodiment two selected wavelengths are derived from a single source with the second reference wavelength being a wavelength which is not significantly absorbed by the gas being measured and the source is switched between two power supplies to ensure the output of the detector is equal for the two wavelengths when the concentration of the measured gas is zero.In a second embodiment two single wavelength sources are used and their combined outputs passed through the sample cell.

摘要： A humidifier provides humidified gases to a patient. The humidifier is very compact, having a gases volume of the order of 60 mls. A microporous water compartment is provided perpendicular to the gases flow to ensure efficient humidification of the gases. Also, a combined temperature probe and heater supply connector is provided which only supplies energy to the heater in the water compartment when the gases temperature sensor is appropriately positioned in the humidifier gases passageway. This reduces the risk of gases at excessively high temperatures being supplies to the patient.
