Abstract: An abrading tool (20) is disclosed as having a tapered arbor (22) and an abrading element (24) including an expandable, axially incompressible helical element (28). A strip (32) of abrasive material on the coils performs a machining operation upon tool rotation. Nuts (40, 44 46) threaded on the arbor provide a means for adjustably positioning the abrading element axially along the arbor to control the diameter of each coil in order to permit initial sizing of the insert and subsequent compensation for wear of the abrasive strip.

Abstract: In a heating apparatus equipped with a sensor element (20) sensing or estimating the state of a substance being heated, for example, a temperature probe containing a temperature sensor such as a thermistor in one end of a metal tube or a humidity sensor sensitive to vapor emanating from the substance being heated, an information data suggesting a hint to the handling of such a sensor element or instructing an appropriate heating sequence or process selected on the basis of the sensed state of the substance being heated is selectively read out from a voice data memory (13) to be synthesized into voice information in a voice synthesizer (14) such as a PARCOR synthesizer, and the voice information is announced to the user at a predetermined time. The user hearing the message can therefore manipulate the apparatus in such a way as to compensate for the inherent defect of the sensor element, and a menu requiring a very delicate procedure can even be successfully cooked without any failure of heating.

Abstract: A double-walled tube section (3/4) with an annular cavity (6) between the walls is inserted between the carburettor (1) and the intake manifold (2) of a normal Otto engine. Air is forced into this cavity through an opening (6') in the outer wall (4), which air is drawn in via an exhaust sleeve (21) of known type and a connecting hose (19) by a pump (10/13) driven by appropriate units from the crankshaft and therefore running proportionally with the latter and is conveyed onward through a heating cartridge (8) of known type. Any desired number of nozzle-like holes (5) of very small diameter are milled in a uniformly distributed fashion all the way round into the inner wall (3) of the tube section in such a way that the inner surface of the tube section (3) remains smooth and the flowing mixture is not forced to condense by impact against projecting parts. Since the heated air under positive pressure can spread out unhindered in the intermediate-wall cavity (6), it rushes in with the same intensity in the case of all the nozzles (5), with the result that, due to their spray action and the temperature gradient in relation to the mixture, maximum atomisation of the fuel and turbulence of the mixture occurs. <IMAGE>
