Title: Conveyorized vacuum applicator and method therefor
Inventor: CANDORE AMEDEO
IPC: B29C43/56
Filed: 1992-08-07
Abstract: A method of and apparatus that is continuously automatically operative in an in-line system is described for applying under heat, vacuum and mechanical pressure a photoresist-forming layer to printed circuit boards that already have been prelaminated by the loose application thereto of dry film as discrete cut sheets within the confines of the surface of the boards whereby a laminate without entrapped air bubbles and closely conforming to the surface contours such as circuit traces of the printed circuit board is obtained.  Featured is a two-part conveyorized vacuum applicator comprising as one part two input conveyors in end-to-end relation and as the other part a belt conveyor and vacuum laminator.  The belt conveyor is characterized in its use of an endless belt having an aperture therein through which, in the vacuum laminating condition of the applicator, the movable lower platen of the vacuum laminator is movable upwards into sealing contact with the upper platen of the laminator, with the printed circuit board to be laminated and a portion of the upper run of the endless belt contained within the vacuum chamber of the laminator.

Patent CA-2076850-A1 (CA)
Title: Method for controlling and regulating the primary nucleation of iron melts
Inventor: BAECKERUD STIG L
IPC: B22D1/00
Filed: 1991-02-25
Abstract: The invention relates to a method of regulating the solidification process in iron casting operations. This is effected by determining the intrinsic crystallisation ability of a base melt and modifying the same. A sample is taken from the base melt in a sample vessel which is in thermal equilibrium with the sample melt before solidification commences. The sample vessel is provided with at least one thermoelement and contains a given and calibrated quantity of inoculant on FeSi-base, this quantity being sufficient to provide a maximum inoculating effect. The sample melt is allowed to solidify and the difference between the lowest temperature in the undercooling phase prior to the eutectic reaction and the maximum temperature in the eutectic reaction phase and the eutectic equilibrium temperature is determined. When this difference exceeds 10 K and 5 K respectively, thermodynamically stable particles of the type spinels or oxysulphides of elements such as magnesium, calcium, zirconium, strontium, titanium and rare earth metals, are added to the melt. These procedural steps may be repeated until the temperature differences fall below the aforesaid limits.

Patent CA-2079977-A1 (CA)
Inventor: LEDET BRENT A
IPC: F25B21/04
Filed: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE:    Sprocket drive mechanisms formed of metal lamina (55) engage belt drive surfaces formed in a modular plastic conveyor belt.          The lamina (55, 55A, 55B) are positioned axially along a rotary drive shaft 46 to mate with drive surfaces extending across the width of the belt. Belt wear from the metal sprocket lamina is reduced by floating at least one lamina axially along the drive shaft (58, 59) to conform with belt positioning under loading and other dynamic conditions. Light weight laminar spacers (52) disposed axially along the shaft are interlocked by notches (56) to mating sprocket lamina notches (53) to maintain a predetermined spacing between lamina while permitting separate sprocket lamina (55, 55A, 55B) to float axially on the shaft with the spacers 52 to permit movement of either single or multiple spaced lamina to migrate axially. The mating spacer and sprocket notches (53, 56) lock the spacer (52) in place to ride on the shavt (46) surface without bolts or fasteners.          (Fig. 8)

Title: Sensitive interferometric parallel thermal-wave imager
Inventor: POWER JOAN F
IPC: G01J9/02
Filed: 1992-10-14
Abstract: A SENSITIVE INTERFERDMETRIC PARALLEL THERMAL-WAVE IMAGER        ABSTRACT      All spatial elements of the thermal-wave image generated in a heated material sample are detected simultaneously ,  or 'in  parallel',  in  the  invention    by  the  use   of   an optical-wavelength interferometer whose sensing arm  contains a combination of the said heated material sample,   contacted to a  thermally  conductive,  optically  reflective  material layer, which is in turn contacted  to  a  phase-shift  medium comprised of an optically  transmissive  layer  of  condensed phase material through which the interferometer  beam  passes and is reflected by  the  optically  reflective      material layer.  The invention thus converts a thermal-wave image into an optical wavelength interferometeric image which can than be rapidly detected in parallel and with high sensitivity  using a  video-camera  or  other  optical  recording   means.   The invention is over one hundred times more sensitive  than prior art  interferometric  instruments  which  use  air   as   the phase-shift medium.

Abstract: EXTERIOR AUTOMOTIVE LAMINATE WITH    PRESSURE-SENSITIVE ADHESIVE          Abstract of the Disclosure A flexible decorative sheet for use in surfacing an automobile body panel includes a first polyester carrier sheet having a high gloss surface, a clear coat of a weatherable    optically-clear    polymer    containing fluorocarbon resin and an acrylic resin coated on the surface of the first carrier sheet, a tie coat on the clear coat, and a color coat containing a chlorinated polymer with dispersed pigments cast on the tie coat and dried.  A pressure-sensitive adhesive layer is formed on a second polyester carrier sheet and then laminated to the exposed   face   of   the   color   coat   to   form   a pressure-sensitive, adhesive-backed composite paint coat between the outer carrier sheets which form protective removable backing sheets for the resulting laminate.  The decorative sheet is applied to a substrate panel by pressure-sensitive adhesive bonding techniques, with the clear coat serving as a glossy, weatherable protective outer  layer  for  the  underlying  color  coat.    The PVC-containing  color  coat  enhances  room  temperature elongation of the finished film to enable application of the laminate to three-dimensionally contoured surfaces. The resulting paint finish has a defect-free, weatherable and durable  outer  surface with  high  gloss  and high distinctness of image, meeting requirements for exterior automotive use.
