Title: An apparatus for detecting carryover particles in the interior of a furnace
Inventor: KYCHAKOFF GEORGE
IPC: F23M11/04
Filed: 1991-04-15
Abstract: An apparatus for detecting the presence of carryover particles in an upper region of a furnace, such as a smelt bed boiler, includes plural spaced apart detectors.  These detectors monitor discrete portions of the interior of the furnace for the purpose of detecting carryover particles in such monitored portions. Signals indicative of the carryover particles are processed to obtain a count of the carryover particles.  The carryover particle count may then be displayed.  For example, the signals from all of the detectors may be averaged with trends and overall changes in count rates then displayed. In addition, the counts from the individual detectors may also be displayed to assist an operator in locating the source of excessive carryover particles in the furnace. An image sensor, such as a charged coupled device (CCD) detector, may be used to provide a visual display of detected carryover particles.  The information on carryover particle count may be used in controlling parameters affecting the performance of the furnace directly, or indirectly by way of operator input.

Title: Apparatus and method for reading helically recorded tracks
Inventor: PISCIOTTA CHRISTOPHER
IPC: G11B15/18
Filed: 1991-04-18
Abstract: A helical system (10) reads tracks (18) on a storage medium (12), including distorted tracks. Each track (18) comprises a plurality of blocks, with each block having unique block-identifying information. A servo system (84) causes a head (16C) to traverse predetermined original azimuthal paths (P0) across the medium (12) for reading the blocks recorded along each of the original path (P0). A controller (50) uses the block-identifying information to determine whether any blocks expected to be read during traversal of the original path (P0) were not read. If expected blocks were not read, the controller (50) repositions the medium (12) and directs that the medium (12) be re-read with the head (16C) offset until the expected blocks are actually read. During the re-read attempts, the read head (16C) is positionally offset to traverse modified azimuthal paths (P1, P2, P3, ... P10).

Title: Brewing device for a coffee machine and method of producing coffee
Inventor: LUESSI ANDRE
IPC: A47J31/40
Filed: 1992-07-28
Abstract: The brewing device comprises a brewing cylinder (9) having a cylindrical bore (10) in which a lower plunger (8) is arranged so as to be freely movable and longitudinally displaceable. An upper plunger (7) is firmly connected to a frame (1). Parallel to the vertically arranged brewing cylinder (9) there is a drive spindle (6) which has guiding means (23). A carrier member (24) connected to the brewing cylinder has further guiding means (25) which are engaged with those of the drive spindle (6). By rotating the drive spindle (6) in one direction or the other, the brewing cylinder is moved upwards or downwards. The brewing cylinder is filled with ground coffee via a funnel (12) which can be pivoted out. In order to determine the quantity of ground coffee contained, the brewing cylinder is moved upwards under time control, at least until a counter force produced by the upper plunger (7) over the compressed ground coffee is as great as the driving force of the spindle. In order to allow the preferred brewing of loose ground coffee, the brewing chamber formed between the two plungers (7, 8) is slightly enlarged again before the actual brewing operation. The device is distinguished particularly by its simple construction with few parts subject to wear, the simple construction being enhanced by the omission of limiting switches as a result of the complete time control of the drive spindle. <IMAGE>
