Patent CA-1309690-C (CA)
Inventor: LEFEBVRE JACQUES
IPC: C25D5/18
Filed: 1988-01-05
Granted: 1992-11-03
Abstract: The invention relates to a process and an apparatus for electrolytically depositing, in a moving mode, a continuous film of nickel on metal wire for electrical use. The process comprises using an activation bath and a nickel-plating bath in which the current density is reduced in the upstream portion of the nickel plating bath and/or the downstream portion of the activation bath and the acidity of the nickel-plating bath is so regulated as to develop the nickel in the form of strongly adhering globules of small diameter, which completely cover the wire. The reduction in the above mentioned current density and control in respect of the current density profile along the bath may be achieved by acting on the position of the electrodes in the bath and/or by interposing screens between the electrodes and the wire.

Title: Automotive instrument virtual image display
Inventor: HEGG RONALD G
IPC: G02B27/00
Filed: 1988-09-13
Granted: 1994-12-27
Abstract: A compact, inexpensive and mass-producible optical display system for an automobile creates a highly visible and sharp, high contrast and pleasing, multi-color magnified virtual image of a primary instrument cluster at a viewing distance which is greater than the actual optical distance between the dashboard and the driver's eyes in order to enhance instrument readability, minimize driver eye strain, and reduce eye focus problems which are associated with transitioning between the far range viewing used for watching the road ahead and the near range viewing used for glancing at the instruments. A non-pupil forming display system uses a single off-axis aspherical mirror with power to create a virtual image of a miniaturized, multi-color passive image source, such as a segmented LCD panel, which is backlighted by a small filament incandescent light bulb. The aspheric surface is optimized to minimize aberrations and reduce vertical disparity and field curvature. The image source is pre-distorted to compensate for distortion in the off-axis configuration. A holographic diffusing screen element laminated onto the image source provides uniform high brightness and uniform contrast over the entire field-of-view which is visible from an eyellipse sufficient to accomodate most of the driver population, minimizes the visual impact of any optical aberrations near the edge of the viewing area, and provides the non-pupil forming system with some of the desirable optical properties of a pupil forming system. The incandescent bulb is positioned at a remote location selected to minimize heat in the region of the image source and to facilitate replacement of the bulb in case of failure. The light emitted by the bulb is collected and focused into the aperture of a fiber optic bundle which splits into a number of ends behind the LCD panel. Ambient reflections are reduced and controlled by a curved and tilted glare shield and a black surface light trap.

Granted: 1995-10-03
Abstract: Compositions containing acrylamide functional polyorganosiloxanes, methacrylate functional and dialkoxy functional terminated polydiorganosiloxanes, a photo-initiator, and an organic titanate provide a dual curing characteristic.   The compositions cure by exposure to ultraviolet radiation and also cure by exposure to moisture, such as atmospheric moisture.  The moisture cure characteristic provides these compositions with the capability to cure in the shadows where the ultraviolet radiation does not reach.  Some of these compositions are useful as conformal coating for printed wire boards.

Title: Laboratory apparatus for optional temperature controlled heating and cooling
Inventor: KNOPF ULRICH C
IPC: F25B21/04
Filed: 1989-05-04
Granted: 1993-05-11
Abstract: ABSTRACT       The invention concerns a handy laboratory apparatus  by which samples can be heated or cooled according to choice. As a  thermal  energy  source a block of  one  or  more  Peltier elements (5) is used,  which,  by inversing the direction  of the  alimentation  current,  can be switched  to  cooling  or heating  mode.  One  of  the thermal  poles  of  the  Peltier elements  contacts a metal block (1),  whereas  the  opposite pole is in contact with a heat exchanger (8). The metal block which comprises an essentially horizontal working surface (2) is  separated  from  the  heat  exchanger  by an  insulating layer (9);  the outer  surfaces of the metal  block  (1)  are protected from any heat exchange with the environment by  the insulating layer (10).  The vessels containing the samples to be heated or cooled are placed onto the working surface (2)or else can be inserted into further metal blocks which serve as working  modules  with  suitable  cavities  for  the   sample vessels and a flat ground face,  which are placed or  screwed onto the metal block (1). The  apparatus  comprises  three  separate  parts.  the heating and cooling device,  the modules receiving the sample vessels and the electric alimentation and control  unit,  the latter   provided  with  a  pulsed  mains  adapter  for   the alimentation  of  the  Peltier  elements  and  an  electronic control circuit,  which,  by choice,   can be connected to  a microcomputer for programming temperature cycles.      The  apparatus  is suited for work in  the  biological, biochemical  or genetic laboratory,  where cycles have to  be accomplished with temperatures partly above and partly  below room  temperature.  It  is  however  transportable  for  work outside the laboratory as well,  e.g. in mobile units such as cars, railways and airplanes.

Granted: 1994-05-03
Abstract: FIBER-OPTIC PHYSIOLOGICAL PROBES            Abstract Fiber-optic sensors suitable for monitoring physiological analyte concentration. An analyte-permeable matrix is disposed in the light path definedby the axial core at one end of an optical fiber segment. The matrix contains anindicator molecule covalently linked to a polymer, preferably methyl methacrylate/methacrylamidopropyltrimethylammonium chloride, N-vinyl-pyrrolidone/p-aminostyrene, methyl methacrylate/hydroxymethyl methacrylate, methyl methacrylate/N-vinylpyrrolidone, or methyl methacrylate/acrylic acid. In representative embodiments, the polymer is approximately 94:6 mole/mole percent of either methyl methacrylate/methacrylamidopropyltrimethylammonium chloride or N-vinylpyrrolidone/p-aminostyrene copolymer.    Drift-free performance is obtained with such sensors having analyte-permeable matrices of significantly less than about 70 microns in thickness. The indicator molecule may be covalently linked to the polymer through an aminoarylalkylamine, such as 4-(aminophenyl)-ethylamine or 4-(aminophenyl)-propylamine. The indicator molecule may be an absorptive molecule, such as phenol red or carboxynaphthophthalein (hydrogen ion analyte), in which case the indicator molecule may be covalently linked to the polymer through either an azo-amide or an amidyl-amide linkage. The indicator molecule may be a luminescent molecule, such as carboxynaphthofluorescein (hydrogen ion analyte) or an oxygen-quenchableporphyrin derivative. The sensor may have a reflector disposed in the light pathdistal with respect to the optical fiber segment to the analyte-permeable matrix. Suitable reflectors include gold foil or films of titanium dioxide, zinc oxide, or barium sulfate. A pCO2 sensor is configured with a gas-permeable but ion-impermeable membrane encapsulating an analyte-permeable matrix that includes a base having a pKa ranging from about 6.0 to about 7.8. The outer membrane may be a silicone, polycarbonate, or urethane. The base may be an inorganic salt, such as bicarbonate, in which case the analyte-permeable matrix should include an antioxidant. Alternatively, the base may be a polymeric base containing, e.g., 2-vinylpyridine, 4-vinylpyridine, histamine, 1-vinylimidazole, or 4-vinylimadazole. Gas-permeability is afforded to the matrix by a minor component of hydrophilic polymer such as polyethylene glycol. A plurality of thepH, pO2, and PCO2 sensors may be disposed together in substantially coterminal array to make a multi-variable probe, which may also include a thermocouple wire.
