Title: Method for fault diagnosis by assessment of confidence measure
Inventor: DOSKOCIL DOUGLAS C
IPC: G06F11/22
Filed: 1992-09-09
Abstract: Abstract of the Invention A method for enabling a diagnostic system to assess, within time constraints, the health of the host system during operation, and to detect and isolate system faults during maintenance, with reduced potential for false alarms due to intermittent real faults and system noise, and for apparent misdiagnosis of the host system health, by use of a Diagnostics by Confidence Measure Assessment (DCMA) process in which a confidence measure is provided for each system test failure assessment, resulting from both the use of specialized persistence processing on many test results from a single source and the use of specialized corroboration processing on many test results from different sources.

Title: Method and apparatus for the treatment of a mineral fibre felt
Inventor: LAUREN HENNING
IPC: D04H1/736
Filed: 1991-03-22
Abstract: 2078988 9114816 PCTABS00007 The invention relates to a method and a device for the treatment of a mineral fibre felt whereby the felt is transported through a transport apparatus while changing the speed thereof. The change of speed is brought about by bringing the felt into contact with at least two elements arranged successively in the transport direction of the felt, the areas of influence of which overlap each other. The apparatus comprises two conveyors (9, 10) arranged opposite each other, between which the felt (3) is transported. Each conveyor comprises at least two shafts (11, 12, and 11', 12', respectively), which are provided with a number of means (16) to be brought into contact with the upper and the lower surface, respectively, of the felt.
Patent CA-2080114-A1 (CA)
Inventor: HOULT ROBERT A
IPC: G01N21/59
Filed: 1992-10-07
Abstract: ID-4043 ABSTRACT OF THE DISCLOSURE An optical transmittance apparatus has a pair of reference channels of glass rods and a pair of sample channels containing sample fluid. A beam splitter and mirror pass a first portion of an incident beam through an ingoing reference channel, and a second portion through an ingoing sample channel. The first portion is reflected back through an outgoing reference channel, and the second portion back through an outgoing sample channel. The beam splitter and mirror directs the outgoing beams into a common outlet path. A partial disk selectively passes either portion. For positioning the disk, poles of a magnet mounted on the disk axle face windings made about an axis perpendicular to the axle, the windings being on the opposite side of a barrier plate from the poles. Current of one polarity through the windings effects one orientation of the disk, and reversed olarity reorients it perpendicularly.

Title: Tape guidance system for belt-driven cartridge
Inventor: EGGEBEEN JAMES A
IPC: G11B15/60
Filed: 1991-08-19
Abstract: The tape guidance system includes at least three tape guidance surfaces (22, 24, 26), each of the tape guidance surfaces (22, 24, 26) having at least one enlarged shoulder (38) extending from the tape guidance surface (22, 24, 26) toward the tape to bear upon an edge of the tape and provide a confinement force parallel to the plane of the tape in a direction transverse to the direction of tape motion. Two adjacent tape guide surfaces (22 and 24) have a close tolerance guide with a distance between the shoulders (38) equal to or slightly greater than the width of the tape. The third tape guidance surface (26) has a wide clearance such that if the tape is to contact the shoulder (36) of the third tape guide (26), it must deviate from a straight line path. The tape has a tendency toward the shoulder (36) of the third guide (26) as a function of the perpendicularity of the tape guide (26) to the plane of the tape. The tape path is such that if a tape is to contact the shoulder (36) of the third tape guide (26) it must contact alternate surfaces of the other two guides (22 and 24). The two adjacent guides (22 and 24), which are contacted on either top-bottom or bottom-top represent the guides which span the location of engagement of the magnetic head.

Title: Disposable diaper having skin-contacting topsheet provided with elastic opening and method for making the elastic opening
Inventor: TANJI HIROYUKI
IPC: A61F13/511
Filed: 1993-04-20
Abstract: A method of forming a skin-contacting topsheet of a disposable diaper with an elastic opening, is described.   The method comprises feeding first and second continuous elastic members in a specific orientation to form crests and troughs which are offset from one another.  These elastic members are glued  onto  the  first  continuous  web  and  form  therewith  a composite web.  A second continuous web is bonded on the first web and forms a second continuous composite web.   Part of the second continuous  composite web  is  cut  away  in  a  specific manner so as to form cut-outs destined to define openings and thereby  form  third  and  fourth  continuous  composite  web members.    These  third  and  fourth  web  members  are  shifted longitudinally   so   that   their   respective   crests   are symmetrically  opposed  to  each  other  in  an  overlapping relationship with the troughs also symmetrically opposed to each  other  but  define  openings.    The  third  and  fourth continuous composite web members are cut transversely along imaginary lines vertically dividing the respective pairs of mutually opposed crests in halves.

Title: Cush cush sleep centring pillow
Inventor: LEGER GEORGE H
IPC: A47G9/10
Filed: 1993-07-27
Abstract: ABSTRACT      A pillow has traditionally been employed as a head and neck support providing relative comfort in the alignment of the cervical spine while lying on one's back, side or other prone position while resting or sleeping.  Improvements to pillow configurations and structure have concentrated on the head and neck support aspect of a pillow's function.  The psychological nurturing function of pillows has been neglected.      The CUSH CUSH SLEEP CENTRING PILLOW embodies the discovery that a pillow functions as a surrogate mother enabling the subject to attain an unconscious infant-like mental state necessary for a stress-free sleep preparedness.  The CUSH CUSH SLEEP CENTRING PILLOW  creates this effect by cradling a subject's head, neck and shoulder areas enhancing the sensation of security and well being.  This is attained by the pillow's unique contours owing to its cleft surface and deeply concave neck support fascia.  This configuration composed of suitable pliable material embraces the subject's upper body in a natural stress relieving manner while offering maximum head, neck and shoulder comfort.

Title: Method for monitoring fluid flow from a volumetric pump
Inventor: NATWICK VERNON R
IPC: A61M39/28
Filed: 1992-08-05
Abstract: A method for determining if fluid is being displaced by a volumetric pump. During a pumping segment of a pumping cycle for the volumetric pump, an outlet cracking valve (52) compresses the flexible tubing until the pressure of the fluid displaced by the plunger exceeds a cracking pressure, at which time the outlet cracking valve opens to enable fluid flow. A cracking flexure (182) provides the cracking force. A flow detector (54) mounted to the cracking flexure responds to the stress generated in the cracking flexure thereby, producing a signal indicative of fluid flow from the volumetric pump. The flow detector also provides an indication when a source of liquid (31) for the volumetric pump has run dry.  The method comprises the steps of processing the signal to determine if it exceeds a predefined threshold that varies as a function of the rate at which the pump is set to deliver fluid.
