The volatile carrier may be held in an edge-on orientation with respect to the flow of hot gases, or transversely with respect to them. The volatile carrier has an inward end that has a cross-sectional profile made to be complementary to that of an insert slot through which the volatile carrier must be inserted for use. An alternative embodiment is shown that uses a candle as a fuel burner. A kit is shown that includes a candle and a volatile carrier that are designed to be exhausted at the same time so that the candle's consumption serves as a use-cue for the volatile carrier.

IPC: B23Q17/24
Filed: 2000-11-17
Abstract: A light source generates a beam of light which is incident on a detector which generates a trigger signal when the beam incident upon it is occluded by a tool. To avoid trigger signals being produced when the beam is temporarily occluded by coolant drips passing through the beam, the detector produces a detection signal each time the beam is occluded, but only produces a trigger signal if a further detection signal is produced in a specified time interval from the generation of an earlier detection signal. Samples of the detection signal are stored in a buffer. When these stored signals indicate a repetitive pattern a trigger signal is issued. <IMAGE>

IPC: B02C4/28
Filed: 2001-01-19
Abstract: A description is provided of a method as well as an apparatus for grinding particulate material, such as cement raw materials, cement clinker or similar materials, in a roller mill (1) by subjecting the material to pressing action in a zone (13) between opposite, rotating surfaces where the material is directed to the grinding zone via a feed shaft (11). The method is peculiar in that the material in the feed shaft (11) is accelerated through the action of gravity to a desired velocity without involving essential air admixture, whereas the apparatus is peculiar in that the feed shaft is essentially of a vertical configuration, with a downwardly reduced cross-section, where the reduction of the shaft´s cross-sectional circumference per height unit is downwardly decreasing.The described configuration of the feed shaft has, surprisingly, proved that the material over a given height of fall may attain high velocities and that this is achievable without involving admixture of air into the material. It has thus been established that it will be possible for the material to attain velocities which are close to the velocity achievable in connection with the free fall of individual particles.

Abstract: <P>PROBLEM TO BE SOLVED: To continuously arrange two turning cams to press processing equipment by arranging within the length of the turning cam a lock mechanism which disables the turning of the turning cams to a cam holder.  <P>SOLUTION: When the end surface of the turning cam 16 forms a continuous surface with the supporting surface 28a of a punch 28, the punch 28 receives pressure through a pad 24 from an upper part and bends, then the uneven parts 16x and 28x formed in each predetermined position of the punch 28 and the turning cam 16 engage with each other. That is the turning of the turning cam 16 is locked in the state where a workpiece w is supported by the continuous surface formed by the supporting surface 28a of the punch 28 and the end surface 16a of the turning cam 16, and the pad 24. The two turning cams 16 can continuously be arranged, very close to each other. Good processing is obtained and the quality of a product is stabilized because the turning of the turning cam 16 caused by the pressure is prevented when the pad 24 contacts the end 16a of the turning cam 16 and during the processing of the workpiece w.  <P>COPYRIGHT: (C)2003,JPO
