Abstract: An apparatus and process for forming a multi-coloured integral vinyl skin shell including a heated mould (32) and dual powder box arrangement wherein the mould is formed to include alternately positioned tear surfaces (34) and recessed surfaces (36). After the first powder box (42) supplies a layer of powder to cover all the surfaces to form a shell, the strips of shell on the tear surfaces (34) are removed, after which the first powder box (42) is replaced by a second powder box (50). The second powder box (50) has a plurality of spaced dams or dividers (52) formed therein such that the dams co-operate with the respective recessed surfaces (36) of the mould to provide clearance therewith that permit different coloured powders in the compartments (72) between the dams to cover the previously cleared tear surfaces and to flow past the selectively formed free ends of the dams to become integrally secured to the adjacent edge portions of the shell segments remaining in the areas of the recessed surfaces of the mould, forming the multi-­coloured integral plastic shell. The dams or dividers (52) have tapered sides (54) formed on their distal ends for approximately the outer two thirds of the width of each dam, and an opening (56) is formed therebetween into a central hollow section for recovering "contaminated" or mixed powders from two adjacent compartments (72).

Abstract: Matching chamber consisting of a cuboid housing having a light source which irradiates the test object. The test object can be viewed through an opening. In such known matching chambers, it is not possible to carry out any reproducible comparisons, since in common with the observational angle the observational distance to the test object is not precisely fixed. The matching chamber according to the invention has an adaptor with observation windows, and a three-dimensionally adjustable test object carrier, so that the observational distance is fixed and the observational angle can be reproducibly set.

Abstract: An electric hotplate for use in a cooker hob comprises a pair of resistive heating elements, R1, R2, having a high positive temperature coefficient of resistance. A relay in series with R2, has its operating coil in series with a temperature sensing resistor T. also having a high positive temperature coefficient of resistance, and connected between the supply terminals by a switch S3, which closes when the energy regulating device S2 is first turned on. 
     In operation, the relay contacts remain open until the hotplate has begun to warm up, so that initial heating is by current through R1 alone. The invention is applicable to hotplates comprising a vitreous enamelled metal plate on which the elements are deposited as resistive films.

Abstract: In a fault tolerant computer system using dual data processing systems each having dual rails and a single memory for each system, handling errors caused when the memory fails to resond during a memory operation. When the memory fails to respond the system classifies the error as a NXM (nonexistent memory) error. The handling of a NXM error involves distinguishing between three situations, i.e., when the error is detected during boot time sizing of the memory, when the error is due to an invalid address generated by software, and when the error is due to a hardware error in memory.

Abstract: A method of compensating scattered characteristics of infrared detector elements, in which a thermal image of a scene is input via a focusing lens (5) onto the detector elements (9). The image on the detector elements is defocused by adjusting the focusing lens; and a first signal level output from each detector element is measured. Then, the image is focused, and a second signal level output from each detector element is compensated using the first signal level. In the case where the image is optically scanned over the linearly arranged detector elements, the first signal level may be averaged over a number of scans to obtain an average level of each detector element, and may be further averaged over a number of different scan directions. The scan direction is rotated by rotating a prism (4) around the light path (P), to predetermined angular positions between 0 to 90 degrees. This enables the defocused light incident on the detector elements to be more properly averaged, to provide an improved average level. Thermal image data of a central portion of the scene may be excluded from the averaging operation, because it includes noise due to a narcissus effect, and because even if scan directions are varied by prism rotation the central image portion stays the same, both effects deteriorating the averaging.

Abstract: A thermostat (15) includes a Proportional-Integral-Derivative (PID) controller (20) and a means (40) for disabling the PID controller for selected periods. The PID controller is disabled during a temperature recovery period, which can be triggered by one or more of many preselected events. The PID controller is re-enabled when the thermostat setpoint less a void offset temperature is reached. To reduce error in future temperature recovery periods, the void offset temperature is adjusted after a temperature recovery by adding the amount of error to the void offset temperature to create a new void offset temperature for use in a next temperature recovery period.
