Patent CA-2041171-C (CA)
Inventor: YERLY MARCEL
IPC: B31B50/16
Filed: 1991-04-24
Granted: 1995-09-12
Abstract: The  invention  concerns  a  process  for  regulating  the parallelism  of  the  two  beams  (5,  6)  of  a  cutting  press designed for converting sheet or weblike matter into package. The press comprises a frame made of a lower crossbar (1) and an upper crossbar (3) connected to one another by means of lateral posts (2). An upper beam (5) is fitted on the upper crossbar (3). A lower movable beam (6) is raised and lowered with each operating cycle by means of a drive system (20a, 20b) supported by the lower crossbar (1) by means of bearings (33a, 33b). The bearings (33a, 33b) can be shifted vertically when the drive system (20a, 20b) is situated in lower dead center position in such a way as to regulate the parallelism of the lower beam (6) with regard to the upper beam (5). When the press  accomplishes its operating  cycle,  a deviation of parallelism (e) is measured when the drive system (20a, 20b) is  situated  in  upper  dead  center position.  When  the  said lower  dead  center  is  reached,  the bearings  (33a,  33b)  are shifted vertically so as to have the lower beam (6) tilt in the  direction  contrary  to  the  tilt  resulting  from  the deviation of parallelism (e) measured in the said upper dead center position.

Title: Enhanced acoustic calibration procedure for a voice switched speakerphone
Inventor: ERVING RICHARD HENRY
IPC: H04M1/60
Filed: 1991-11-13
Granted: 1995-09-05
Abstract: An acoustic calibration circuit in a voice switched adaptive speakerphone accurately determines the type of acoustic environment of both large and small rooms having either harsh or favorable acoustics. The calibration circuit determines the acoustic environment of a room by emitting a tone burst through aloudspeaker associated with the speakerphone and generating an echo decay parameter that is indicative of the duration of echoes from the tone burst signal measured with a microphone also associated with the speakerphone. The echo decayparameter is generated from a composite representation of the acoustic response for those echoes having the largest returned amplitude level measured at each one ofmultiple predetermined time intervals by the calibration circuit. By examining the amplitude levels in the composite representation at selected ones of the multiple predetermined time intervals, the echo decay parameter or estimate for the additional time required for the echoes to dissipate to a desired level is generated. If after performing a first measurement of the room acoustics at a prescribed first time period, the calibration circuit determines that the room echoes have not dissipated to an acceptable level in this first time period for generating a satisfactory echo decay parameter representative of these echoes, the calibration circuit regenerates the tone burst into the room a second time and then measures the resulting level of the acoustic response over an extended time period. From the echo decay parameter and the composite representation, a time-domain acoustic response is generated. Thistime-domain acoustic response provides an estimate of both the maximum returned amplitude and expected duration of the echoes. This information is then used by the speakerphone in adapting its operating parameters. If the room acoustics are harsh, the speakerphone adapts by keeping its switching response comparable with that of a typical analog speakerphone. If acoustics are favorable, however, it speeds up the switching time, lowers both the break in thresholds and the total amount of inserted switched loss.

Title: Control of furnace cleaning for reflective ash using infrared imaging
Inventor: CARTER HUDSON R
IPC: F23M11/04
Filed: 1991-12-02
Granted: 2000-02-08
Abstract: A method and apparatus for monitoring reflective ash deposited on a furnace wall to be cleaned comprises an infrared video camera or other mechanism for taking an infrared image of the fur-nace wall. The image must include an area to be cleaned by the waterblowing as well as a surrounding uncleaned area. Photo detectors or other mechanisms are utilized to measure the image intensity at locations on the cleaned and uncleaned areas with a ratio between the intensities being taken. The cleaned area has low reflectivity and is dark compared to the uncleaned area which is white and has high image intensity. The image intensity ratio between the cleaned area and the uncleaned area thus rises from a low level immediately after waterblowing to a high level which approaches unity as the initially cleaned area becomes as unclean as the uncleaned area. This can be used as an indication when waterblowing must be manually initiated, or the ratio signal can be used directly to operate an automatic system to initiate waterblowing.

Title: Process to defend objects emitting an infrared radiation and droppable bodies to carry out the process
Inventor: BANNASCH HEINZ
IPC: F41H9/06
Filed: 1992-03-31
Granted: 1996-06-25
Abstract: A process is provided to defend objects emitting an infrared radiation, in particular ships, against missiles, which are equipped with intelligent infrared seeker heads.  Following location of the missile, adjacent to the object a large area pyrotechnical perturbing radiation cloud, which releases in a short period of time high infrared radiation, which hashes the locking on and pursuit electronics of the seeker head, and subsequently releases for a comparatively long period a weak infrared radiation, is produced between the object and the missile. Immediately following the end of the high radiation phase of the perturbing radiation cloud, several fake target clouds are set up that lead the missile then step-by-step away from the object to be defended. The perturbing radiation clouds are produced by the droppable bodies, whose active masses comprise phosphorus flares and phosphorus pellets.
