Patent CA-1294833-C (CA)
Title: Critical temperature indicating device
Inventor: EMSLANDER JEFFREY O
IPC: G01K11/06
Filed: 1988-09-13
Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE    This invention relates to critical temperature indicating devices which provide an irreversible visual signal that a product has been exposed to a predetermined temperature. This invention provides a device for indicating a critical temperature, such as, for example, the freezing point of a liquid. The device comprises a sheet which is a layer having a multiplicity of micropores therein and a mixture comprising at least two liquids, said mixture incapable of wetting said sheet at a given temperature, but capable of wetting said sheet when the temperature of said mixture reaches a critical value, such as the freezing point of one of the liquids in the mixture. The micropores, or voids, in the microporous layer cause scattering of transmitted light, causing the microporous layer to appear opaque. When the voids are filled with a liquid having substantially the same index of refraction as the material of the microporous layer, the filled voids do not scatter transmitted light, thus rendering the microporous layer transmissive to visible light. A visible indicator is associated with the layer of microporous film such that at a temperature above the freezing point of the liquid composition, the visible indicator is masked by the layer of microporous film, but at a temperature at or below the freezing point of the liquid composition, the liquid wets out the layer of microporous film, thereby allowing the visible indicator to be seen through the layer of microporous film.

Title: Process suitable for the simultaneous production of preforms
Inventor: HOFSTETTER OTTO
IPC: B29C47/70
Filed: 1989-05-10
Granted: 1994-04-05
Abstract: Abstract:     The present invention is directed to a process suitable for the simultaneous production of preforms consisting of polyethylene terephthalate (PET) fed and distributed to a plurality of cavities.  In order to reduce the occurence of acetaldehyde formation in a cavity, for example, a heated distributor block used in the production of preforms of the PET material, the material flowing through a channel is subjected to additional turbulence.  To this end, an element, preferably of metal, is installed in the channels, such element being provided with sets of radial spokes which are azimuthally offset in relation to each other in the axial direction.  Besides inducing turbulence, such spokes act as homogenizing elements serving to diffuse heat over the cross section of the flowing process material.

Title: Electronic combination lock with changeable entry  codes, lock-out codes and programming code
Inventor: ANDERSON CHARLES E
IPC: G06F7/00
Filed: 1989-07-10
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE A keyless electronic combination lock is adaptable for placement on a door,  and operates independently of any other locks and without a central control system. The  lock has  a keypad for entering combinations,  a random access memory (RAM) into which the entered data is  loaded,  a  microprocessor,  and  an  electrically erasable programmable read only memory (EEPROM).  One or more entry codes for opening the lock are stored in the EEPROM and loaded into the RAM when the lock is powered-up.  To open the lock, one of these codes or a master entry code must be entered at the keypad.  Each entry code can be individually prevented from opening the  lock  by  entering  a  corresponding  individual lock-out  code.   All  of  the  entry  codes  can  be locked-out  by  entering  a  master  lock-out  code,  by entering all of the individual lock-out codes or by throwing  a dead bolt.   The master  entry code works regardless of the lock-out status and regardless of the dead bolt.   To change  lock-out status,  the  lock-out code  is  simply reentered.   All of the  codes can be changed  as desired by  entering  a programming  code, followed  by   an   identifying  code   to   tell   the microprocessor which code to change.   The programming code  can be  installed  in the  lock  at  the  time  of manufacturing the lock,  and it can be changed during use in the field.

Title: Procedure for the bleaching of pulp in which oxygen is used as the oxidating bleaching chemical
Inventor: VAHERI MARJA
IPC: D21C9/10
Filed: 1989-09-18
Granted: 1997-12-23
Abstract: The invention concerns a procedure for the bleaching of pulp using oxygen as an oxidating bleaching chemical.  The essential features of the invention are that oxygen is used in the first oxidation stage of the bleaching process, that the pulp is subjected to enzyme treatment, and that after oxygen bleaching and enzyme treatment, the pulp is washed. According to the invention, the subsequent oxidation stages can be implemented using bleaching chemicals containing chlorine, e.g. chlorine gas and/or chlorine dioxide.  The use of enzymes allows partial burning of the washings and enables the amounts of toxic compounds in the bleaching effluent to be reduced, simultaneously lowering its chemical oxygen demand.

Abstract: -i-Abstract of the Disclosure High speed sheet feeders receive blocks or bricks of paper sheets, cards or folders stacked edgewise on a downsloping supply ramp, and singulate these for edgewise feeding in rapid succession.  The frontmost sheets ready for feeding are buckled and fanned at their upper edges, and their lower edges are arched forward to form a dimple or ridge-shaped pocket by an underlying central traction simulator  A pair of ganged or synchronized feed belts engage the frontmost sheet and propel it rapidly downward edgewise, and a slanting discharge belt receives and diverts the sheet at even higher speed between the discharge belt and a tractive pinch roller.  A transfer assembly beneath the discharge belt may receive sheets from an adjacent feeder and interleave them upon command with sheets delivered by the discharge belt.

The apparatus is comprised of a unit which is responsive to the non-training set speech signals for sampling the speech signals to produce digital speech signals, to form frames of the digital non-training set speech signals, and to process each frame to generate a set of classifiers defining speech attributes. A unit is also provided for estimating statistical distributions for voiced and unvoiced frames without prior knowledge of the voicing decisions for past ones of the frames of digital non-training set speech. A unit is provided which is responsive to these statistical distributions for determining decision regions representing voiced and unvoiced digital non-training set speech. A unit is then provided which is responsive to the decision regions and a present one of the frames for making the voicing decisions. Finally, a unit is provided which is responsive to the determination of the voicing decision in the frame of the digital non-training set speech signals for transmitting a signal to a data unit for subsequent use in speech processing.

Abstract: Nitrogen oxide pollutants are substantially reduced and sulfur dioxide minimized in multisolid fluidized beds by staged combustion of the fuel. The lower combustion region is operated at substoichiometric conditions such that NOx is reduced by carbon and carbon monoxide to nitrogen gas. The upper combustion region is operated at excess oxygen conditions to complete the combustion of char and carbon monoxide. Elevated temperature excursions in the upper region which deter sulfur capture are prevented by recycling cool entrained bed particles therethrough.

Abstract: A urine collection receptacle has a body formed by walls sealed along the periphery. First and second sheets form a drape which is situated between the walls. The drape extends across the body below the inlet, with the side edges of the drape sealed along opposing sections of the periphery. The sheets are sealed to each other along spaced vertical lines to define the body of a flap valve. The vertical sealed lines are severed to detach the flap valve body from the remainder of the drape. The sheets may also be sealed along oppositely oriented, downwardly inclined lines to form a funnel to direct liquid from the inlet toward the flap valve. The structure facilitates manufacture because the drape is sealed to the receptacle body in the same automated operation which seals the periphery of the walls.
