Title: Multi-roller electrostatic toning
Inventor: PICKETT JOHN E
IPC: G03G15/08
Filed: 1992-01-08
Granted: 2001-07-03
Abstract: Non-magnetic and non-conductive powdered toner is applied to a rotating image cylinder having an electrostatic pattern. A container having a closed bottom and sides and open top contains the powdered toner. The powder is fluidized by introducing air through a pervious closed bottom of the container, and by vibrating the container. The toner is simultaneously stirred and electrically charged to a potential of greater than about 7kv (plus or minus polarity) by rotating elements with radial pointed appendages in the container. Toner is transferred from the container to an image cylinder at an exposed nine o'clock position of the image cylinder by a plurality of transfer cylinders. A first transfer cylinder is mounted so that its periphery is just above the open top of the container and an applicator cylinder has its axis below the axis of the first cylinder, and its periphery adjacent both the first cylinder and the image cylinder. A second cylinder is for the removal of opposite sign charged toner and low charge toner from the applicator cylinder.      Scrapers scrape unused toner from the first and applicator cylinders so that it falls into the open top of the container.

Abstract: ADAPTIVE TRANSMISSION SHIFT PRESSURE CONTROL WITH CLOSED-LOOP COMPENSATION            Abstract of the Disclosure An adaptive transmission pressure control based on a measured interval of speed ratio progression includes a closed-loop control which compensates for factors that tend to extend the speed ratio progression.  The control detects the rate of speed ratio progression during a first portion of the inertia phase of the shift, and employs closed-loop pressure control to maintain the detected rate of progression through completion of the shift.  This ensures that the measured progression interval will accurately reflect the relationship between the scheduled pressure and the resulting shift ratio progression, regardless of factors which would otherwise influence the measured shift progression interval.  Consequently, the correlation between shift quality and the measured shift progression interval is preserved.

Filed: 1992-06-23
Granted: 2002-06-11
Abstract: This invention relates to a device and method for assisting people in changing their behaviour and in particular assisting people to stop performing an acquired behavioural response such as using tobacco products, using alcohol, or over-eating. The device and method interrupt a user's acquired behavioural response to stimuli before a decision regarding a course of action is made. A set of symbols representing alternative responses to the acquired behavioural responses is then displayed to the user to encourage the user to perform an alternative response.      The user acknowledges whether the acquired behavioural response was performed or whether one of the alternative behavioural responses was performed. The device records the number of times either response was performed for later analysis and record keeping.

Title: Methods for diagnosing human influenza and 4-position modified chromogenic n-acetylneuraminic acid substrates for use therein
Inventor: TURNER GREGORY A
IPC: C07H15/203
Filed: 1990-12-27
Granted: 1998-06-30
Abstract: Chromogenic derivatives of N-acetylneuraminic acid modified in the 4-position by eliminating the hydroxyl group, by replacing the hydroxyl group with fluorine, or by replacing the hydrogen of the hydroxyl group with methyl are used as substrates in colorimetric assays for human influenza neuraminidase activity in clinical sp ecimens for the purpose of selectively diagnosing influenza infection.

Title: Expansion shell assembly
Inventor: CALANDRA FRANK JR
IPC: E21D21/00
Filed: 1992-11-06
Granted: 2000-06-13
Abstract: A tapered camming plug positioned within an expansion shell is threaded onto an upper end portion of an elongated bolt advanced behind a resin cartridge system into a bore hole drilled in a rock formation. A bearing plate is carried on the opposite end of the bolt and abuts the rock formation surrounding the bore hole. The cartridge is ruptured by upward thrust and rotation of the bolt to release the resin components for mixing. The mixed resin flows downwardly in the bore hole into surrounding relation with the camming plug and expansion shell.      The expansion shell includes a plurality of expansion fingers each formed integral at one end portion with a ring end portion of the shell and extending upwardly to a free end portion for outward expansion into engagement with the wall of the bore hole as the camming plug advances downwardly on the bolt after the resin is mixed. The shell ring end portion has a circular opening for receiving the bolt and an outer, non-circular surface forming a wall having areas of non-uniform thickness to increase the area of the annulus between the ring end portion and the wall of the bore hole. The increased area around the ring end portion facilitates the insertion of the expansion shell assembly into the resin by permitting the resin to flow past the shell and the ring end portion and bond the expansion shell and a portion of the bolt to the rock formation within the bore hole.

Title: Image processing with anti-forgery provision
Inventor: NISHIKAWA EIICHI
IPC: H04N1/40
Filed: 1993-02-24
Granted: 1999-09-28
Abstract: A discriminating circuit discriminates the degree of similarity between an image represented by an input image signal and a predetermined specific image. A CPU outputs a pattern-level selecting signal based upon the results of discrimination performed by the discriminating circuit. A pattern adding circuit modulates an internally stored specific pattern in accordance with an added-color designating signal and pattern-level selecting signal produced by the CPU, and adds the modulated specific pattern to the image signal.      As a result, a pattern specific to the apparatus is added in a reliably identifiable manner to an image output having a high probability of containing the specific original. In the case of an image output having a low probability of containing the specific original, the specific pattern is added to this image output in such a manner that the picture quality thereof is not diminished by the pattern.

Granted: 2000-06-20
Abstract: A method of low-NOx combustion and a burner device for effecting the same, in which a primary fuel is injected in a direction from the periphery of stream of a combustion air towards that same combustion air, effecting a first combustion, so as to create a generally cylindrical primary flame covering the combustion air, whereby a secondary fuel injected towards the combustion air is shielded or intercepted by such primary flame from the combustion air, while causing NOx in the primary flame to be reduced by the secondary fuel, after which, a second combustion is effected by bringing the secondary fuel to contact with a portion of the combustion air penetrating through the primary flame, at a downstream side.      This arrangement permits more positive decrease of NOx density in an exhaust gas.
