Title: Modifications of visual acuity by thermal means
Inventor: HOOD LARRY L
IPC: A61N1/00
Filed: 1994-08-22
Abstract: A thermo-keratoplasty system and method for locally heating and reshaping a cornea in a manner that produces a minimal regression of the corneal correction. The system includes a probe (12) that is coupled to a power source (14) which can provide a predetermined power, frequency and time duration that creates a thermal profile within the cornea which extends from the epithelium into the corneal stroma. The electrical return of the probe is a lid speculum (202) which maintains the eyelids in an open position. The probe (12) is placed into contact with the cornea and energy is transformed from the power source (14) to the eye, through the lid speculum (202) and back to the power source (14). The energy from the power supply is focused by a probe tip (240) that locally heats and denatures the cornea, and causes a subsequent shrinkage of corneal tissue. A pattern of denatured areas can be created around the cornea to correct the vision of the eye.

Title: Method and apparatus for producing highly-oriented polyester sheet
Inventor: VAN ERDEN DONALD
IPC: B29C43/24
Filed: 1996-05-15
Abstract: A method and apparatus for producing highly-oriented poly-ester sheet comprises a two-stage drawing process. The first draw-ing stage is performed within a zero-gap milling and stretching roller assembly comprising a pair of opposed rollers defining a nip therebetween and wherein the rollers are rotated in opposite directions at different lineal surface velocities such that a pre-determined draw ratio is defined therebetween. Amorphous polyester sheet is conducted through the nip of the opposed rollers, and as a result of the simultaneous milling and stretching of the polyes-ter sheet, the amorphous polyester is transformed into crystalline polyester as a result of orientation-induced crystallization. The crystalline polyester sheet is heated above the glass transition temperature (Tg) immediately downstream of the nip defined between the pair of opposed rollers, and an exit bridle assembly is dispos-ed downstream of the pair of opposed rollers. The rollers of the bridle assembly are rotated at lineal surface velocities which are greater than the lineal surface velocity of the downstream one of the pair of opposed rollers such that a second draw ratio is defin-ed with respect to such downstream one of the pair of opposed roll-ers. The heating of the crystalline polyester sheet facilitates the additional stretching thereof within the second drawing stage of the apparatus, the overall drawing ratio being approximately 6:1.          Highly oriented polyester, having tensile strength values of approx imately 100,000 psi, and modulus values of approximately 3,000,000-5,000,000, is achieved.

Patent CA-2177935-A1 (CA)
Inventor: KELLY THOMAS L
IPC: E04D11/02
Filed: 1996-05-31
Abstract: An improved roofing system is presented comprising a built-up roof (BUR) assembly or modified roof membrane assembly (MRM) which is adhered to gypsum, concrete or composite sheets or panels which have been loose-laid over a roof substrate. This allows the BUR or MRM assemblies to conduct heat to or receive heat from the thermal mass of the loose laid mass-weighted sheets immediately below the BUR or MRM assemblies. The gypsum panels, preformed concrete panels, poured-in- place concrete or composite mass-weighted construction panels which are placed between the BUR or MRM assemblies and the roof substrate causes more gradual changes in temperature between the roof assembly and the roof substrate. Because the BUR or MRM assemblies, which are attached to the loose laid gypsum or the like panels, can move independently of the insulated roof substrate panels with the expansion and contraction concomitant thermal cycling, wrinkles and tears previously associated with the joint lines of the roof substrate panels are practically eliminated. Additionally, the weighted roof assembly of the invention aids in wind uplift protection by providing a floating, moveable mass under the BUR or MRM assemblies by distributing wind uplift shock away from the perimeter edge of the roof and into the interior thereof.

Patent CA-2178987-A1 (CA)
Title: Trolling motor clutch mechanism
Inventor: HENDERSON WILLIAM A
IPC: B63H20/00
Filed: 1996-06-14
Abstract: An improved technique for operation and assembly of trolling motors is dis-closed. The direction indicator assembly is flexibly mounted to allow its initial assembly in any direction. The direction indicator can then be flexibly moved and twisted into the proper orientation where its arrow aligns with the direction of the thrust motor. If any fine-tuning is required, the direction indicator can then be turned relative to a gear mounted to it. The positioning system for the stem sup-porting the thrust motor includes a clutch system to avoid reverse movements of the drive system for the stem supporting the thrust motor. Fine adjustments can be made to the direction indicator, even after the thrust motor has struck a fixed object and rotated through the use of a clutching system. The clutching system is automatic and allows the continuation of steering commands to the thrust motor once the shock load that has caused the clutch to disengage is removed.

Patent CA-2180905-A1 (CA)
Inventor: ISHIZU FUMIO
IPC: H04L27/14
Filed: 1996-07-10
Abstract: A digital demodulator capable of a high speed operation.          An automatic frequency controller (AFC) estimates a frequency deviation .DELTA..omega. on the basis of a detected sample signal which is outputted at an oversampling interval by a receiving filter.          The AFC can estimate the frequency deviation before a stable operation of a bit timing recovery circuit (BTR).  The AFC generates a frequency deviation correcting signal for each decision timing on the basis of the estimated frequency deviation, and decision timing information from the BTR.  A multiplier eliminates a frequency deviation component from an input signal in response to the frequency deviation correcting signal.

Title: Method of printing a multiple color image using heat sensitive inks and applying a polymer surface preparation material to a substrate
Inventor: HALE NATHAN S
IPC: B41M3/00
Filed: 1995-01-26
Abstract: An image is permanently transferred to a substrate having a cotton component, or an absorbent component, from a medium printed with the image.  When using a thermal printer and heat activated ink, a polymer surface preparation material and the ink are transferred by the thermal printer to the medium from a ribbon, without activating the ink or the surface preparation material during this first transfer. When using a computer driven printer, a polymer surface preparation material is printed by the computer onto the medium and over the image without printing the material beyond the margins of the image. When using color thermal ink jet printers, heat sensitive inks containing a polymeric surface preparation may be used as an ink formulation. The image is then transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to activate and transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.
