Patent CA-2005319-C (CA)
Inventor: LAUBE DANIEL J
IPC: F16K21/16
Filed: 1989-12-13
Granted: 1998-04-21
Abstract: A metering valve is provided having a piston assembly mounted for movement between open and close modes.  The piston assembly is biased to assume a close mode.  The piston assembly assumes an open mode only when a predetermined external force is applied to a valve actuating element forming a component of the metering valve.  When the external force is removed, the piston assembly automatically returns to the close mode.  The rate of movement of the piston assembly during a first segment of travel from the open mode to the close mode is substantially slower than the rate of movement during a second segment of the travel.

Title: Lightguide coating control
Inventor: FRAZEE RALPH EDWARD JR
IPC: C03C25/10
Filed: 1989-12-19
Granted: 1995-12-26
Abstract: A laser directs a laser beam at an optical fiber and the resulting forward-scattered light is detected by a detector. The energy of the forward-scattered laser light is monotonically inversely proportional to the thickness of a carbon coating on the optical fiber. A computer generates an electrical signal for controlling carbon coating thickness by driving a valve to control the flow of acetylene from a source used to coat the optical fiber in a coating chamber.

Title: Adaptive thresholding technique
Inventor: ASSAEL DAVID
IPC: G06V10/28
Filed: 1990-02-13
Granted: 1994-04-19
Abstract: ADAPTIVE THRESHOLDING TECHNIQUE                 ABSTRACT OF THE DISCLOSURE An adaptive thresholding technique is calculated by using a real-time 16 pixel running average (RA) 18 to which is added an offset value.  The offset value 38 is the product of a programmable factor (alpha) and a Sum Absolute Difference (SAD) noise measurement.  The adaptive threshold 42 is compared by a comparator 48 with a delayed analog video signal intensity value on line  46  for the pixel associated with the adaptive threshold.  The comparator 48 provides a binary video output for further processing.  A relative video output may also be provided by taking the difference of the analog video signal 46 and its corresponding running average 18.

Title: Method and apparatus for compensating for non-linear flow characteristics in dispensing a coating material
Inventor: HALL ROBERT C
IPC: B05C11/10
Filed: 1990-05-30
Granted: 1998-12-01
Abstract: A fluid dispensing apparatus is provided with a controller for modifying a tool speed signal from a robot and to generate a corrected signal to the dispenser nozzle flow controller which compensates for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies.  The corrected tool speed signal is generated by computing the ideal flow for the tool speed signaled, comparing the computed flow with actual flow data stored in a memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison.  The stored data is acquired by operation in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table.  The method of operation corrects non-linear flow phenomena such as the shear-thinning effect.

Abstract: The present invention provides a method of reducing or preventing skin irritation of a weak base drug by inhibiting the accumulation of the drug in the lysosomes. The drug is irritating to humans, i.e., the drug is susceptible to inducing skin or mucosa irritation in a human when the drug is transdermally administered to the human at a therapeutically effective rate. Irritation reduction or prevention is induced by coadministering to the skin or mucosa of the human:   (a) a therapeutically effective amount of a weak base drug which is irritating to humans, at a therapeutically effective rate over a predetermined period of time; and (b) an effective amount of an agent capable of inhibiting the lysosomal uptake of the drug to reduce or prevent irritation to the skin or mucosa.

Title: User-friendly document input
Inventor: COY GERALD L
IPC: B65H7/08
Filed: 1991-07-11
Granted: 1999-03-16
Abstract: A method and apparatus for document feeding for improved operator document manual insertion in which a document may be manually initially inserted into a document input area and released. The document is sensed in the document input area by a document sensor, and then automatically clamped in a document feeding nip which is automatically actuated in response to the document sensing, and then the document is automatically fed. Here, a first time delay period is provided between the sensing of the manually inserted document and the automatic clamping of the document. A second time delay is provided between the automatic clamping and the automatic feeding of the document. Preferably the automatic clamping of the document in the feeding nip is with a limited initial nip force sufficiently low to allow manual document retraction without document damage during the second time delay period. Furthermore, preferably the document sensing automatically actuates an operator display, but here a substantial present time delay is provided between the sensing of the manually inserted document by the document sensor and the automatic actuation of the operator display.

Granted: 1996-01-30
Abstract: This invention relates to an apparatus for manufacturing ribbed pipes. The central axis of the apparatus has a core (8, 9, 10) about which a material in a plastic state is extruded through a nozzle (11). The end of the core has a kernel (10) of a substan-tially constant diameter which calibrates the inner surface of the pipe. The outer surface of the pipe acquires its form from axially moving moulds (1, 2). The kernel has a heated initial zone and a cooled end zone (14, 15). In known apparatus, the grooves (13) of the moulds are often incompletely filled and the inner surface of the pipe is made uneven. These drawbacks can be avoided by disposing a cooled widening end face (20) at the outset of the end zone (15) of the kernel.
