Patent CA-2006346-A1 (CA)
Title: Method of making fiber optic couplers
Inventor: BERKEY GEORGE E
IPC: G02B6/24
Filed: 1989-12-21
Abstract: A fiber optic coupler is formed by providing a glass tube having a longitudinal aperture extending therethrough.      Protective coating is removed from a region of a first optical fiber intermediate the ends thereof. Protective coating is removed from an end region of at least one other optical fiber. The coated portion of the first fiber is threaded through the tube until the uncoated region thereof is near the tube end. The uncoated region of the second fiber is placed adjacent that of the first fiber, and both uncoated regions are simultaneously fed into the tube aperture. After the threading operation has continued until the uncoated regions extend through the midregion of the tube, the midregion is heated to collapse it about the fibers, and the central portion of the midregion is drawn to reduce the diameter thereof over a predetermined length.

Title: Polyamide-polyimide and polybenzoxazole-polyimide polymers
Inventor: KHANNA DINESH N
IPC: C08G73/14
Filed: 1990-02-23
Abstract: ABSTRACT      The  present  invention  provides  polyamide-polyimide  and polybenzoxazole-polyimide polymers derived therefrom with improved processing and film characteristics having incorporated into the polymeric backbone the polymeric condensation residuum of novel aromatic diamino compounds having the formula:              wherein A is selected from the group consisting of SO2, O, S, CO, C1 to C6 alkyl, perfluoroalkyl or perfluoroarylalkyl having from 1 to  10  carbon  atoms  and  a  carbon-carbon  double  bond directly linking the two aromatic groups, and R is selected from the group consisting of hydrogen, hydroxy and C1 to C4 alkoxy.      The  polyamide-polyimide  polymers  of  this  invention  are prepared by reacting compounds of the above formula,  alone or admixed with other aromatic diamines, with one or more aromatic tetarcarboxylic      acids      or      anhydrides      thereof. Polybenzoxazole-polyimide derivatives of such polyamide-polyimide polymers are prepared utilizing compounds of the above formula wherein R is hydroxy or C1 to C4 alkoxy, and by subjecting the resulting alkoxy or hydroxy-substituted polyamide-polyimide to a dehydrating and cyclizing reaction to form the oxazole linkage which gives rise to polybenzoxazole-polyimide polymer.

Patent CA-2012616-A1 (CA)
Inventor: YOSHIDA HAJIME
IPC: B41N3/00
Filed: 1990-03-20
Abstract: Disclosed is a correction fluid prepared by adding a stannous chelate compound having an acidic phosphate ester of an aliphatic alcohol as a ligand to an aqueous acidic solution. The correction liquid forms a hydrophilic stannous chelate compound precipitate, when the pH value of the liquid is elevated. Accordingly, where the correction liquid is coated on the unnecessary line image part of an electrostatic master paper plate and the pH value of the thus coated liquid is elevated, the unnecessary line image part of the plate is to be coated with the hydrophilic and water-insoluble stannous chelate compound so that it becomes insensitive to ink  The operation for such correction may be effected at any stage before or after the lipophobication treatment of the electrostatic master paper plate to be corrected with the correction fluid.

Abstract: ABSTRACT OF THE DISCLOSURE.     To prevent damage to a combination folding blade -sheet gripping cylinder (6) which also carries counter cutter strips (8) at a predetermined fixed diametrical distance from the center of rotation of the cylinder, and a folding jaw cylinder, upon occurrence of paper jams, paper accumulations or stoppers in advance of the nip between said cylinders, the folding jaw cylinder is formed with recesses, such as a circumferential groove (18, Fig. 4) or a flattened surface (20, Fig. 3) in the region which, upon roll-off of the cylinders against each other, will be opposite the counter cutting element (8) of the combination folding blade - gripping cylinder (6).  This recessed area, thus, will be located between adjacent folding jaws (13) on the folding jaw cylinder.  The width of the gap at the nip, thus, will be increased at the position of the unyielding counter cutter element (8) on the combination   folding blade -gripper cylinder (6).  At other circumferential regions, the diameter of the folding blade - gripper cylinder can be increased by adjusting its circumferential dimension by a suitable circumferential dimension adjustment system (17) retained in eccentrically journalled bolts or rods.   The recess, that is, the groove (18) of the flattened surface (20) can be filled by an elastically compressible material, or bridged by a yielding material, such as a strip of spring steel.

Abstract: 2031207 9013276 PCTABScor01 An oral appliance for tongue thrust correction includes a pair of thin wire filament loops pivotally coupled together for limited pivotal movement about an axis. One loop forms a palatal portion (10) and the other loop forms a lingual portion (28) which includes a bridge (34) for spanning the dorsum of the tongue. A spring urges the bridge (34) away from the palatal portion (10) and against the dorsum whereby contact with the dorsum encourages the tongue to a position through the palate and lingual portions and to properly seat on the rugae for maintaining proper proprioceptive sense. The bridge (34) includes a loop (36) for dispensing a stimulant (37) for increasing the swallowing frequency. The corrective habit established by use of the appliance inhibits snoring and brings about improvement in malocclusion, TMJ and related disorders.
