Title: Child's automotive safety booster seat with a view
Inventor: SILVERMAN MATTHEW H
IPC: B60N2/28
Filed: 1994-03-10
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention features a child's automotive safety booster seat that has enough rigidity to withstand high compression, and, at the same time, is soft and comfortable for the child occupant.  Conflicting safety design objectives are accomplished by constructing the center of the booster seat from a rigid styrofoam, which is overlaid with a thin layer of soft urethane foam for comfort.  The soft urethane roam also serves to provide a flexible intersection allowing the child seat to bend and conform with almost any angle of backseat currently provided by automobile manufacturers.  This flexibility about the intersection does away with any need for a mechanical hinge to provide for the angle adjustment.  Added strips of batten can be added to the rigid styrofoam to provide further stiffness and support.

Title: Naphthol couplers
Inventor: CHAN ALEXANDER C
IPC: C09B67/42
Filed: 1994-04-11
Abstract: 2-substituted-1-naphthols when coupled with an oxidation dye precursor in an oxidative dye system produce a long lasting intense color to hair. Use of such couplers makes available to the colorist novel oxidation hair dyes which surprisingly show a color shift to the red. Dyestuffs prepared through use of the 2-substituted-1-naphthol couplers are substantially more acid-fast compared to like dyestuffs using a 1-naphthol coupler.      Compositions and a method of dyeing hair are also disclosed.

Filed: 1994-07-20
Abstract: A roof drain for draining rainwater from a roof. A bell-like strainer is supported by a compression/tension unit including resilient means, which unit is in turn mounted to a drainage sleeve that communicates with a leader.  The strainer is secured to the drainage sleeve by a threaded bolt that passes through bores in the strainer and the compression/tension unit, and engages a nut received by the resilient means.  Tightening the bolt moves the strainer downwardly into a substantially watertight fit with roofing membrane interposed between a skirt of the strainer and a collar on the drainage sleeve.  The resilient means, which may be resilient material, a spring or the like, provides continuous tension between the strainer and the drainage sleeve.

Patent CA-2147321-A1 (CA)
Inventor: WHITESIDE GEORGE D
IPC: B41J17/28
Filed: 1995-04-19
Abstract: ABSTRACT OF THE DISCLOSURE     A system for sheetwise dry processing thermographic print media is disclosed.  The media is a laminate of a substrate with an attached frangible tab, a peel sheet and an adhesive image forming layer.   A feeder feeds the sheets one at a time from a first position and orientation to a second position and orientation with the tab at a trailing end.  A print roller is mounted for reversible rotation in infeed and outfeed directions.   The print roller has clamps for engaging the sheet as received from the sheet feeder.  A thermal printer cooperates with the print roller for thermally exposing the substrate.   A peeler receives the sheet from the print roller with the tab at the leading edge.  The peeler captures the film and engages the tab bending the substrate about the score line causing it to fracture.  The peeler pulls the substrate and adhered image layer apart from peeler sheet to thereby produce a peeled substrate with an image layer and a waste peeler sheet.  A thermal laminator receives the substrate and image layer for thermal laminating engagement with a thermosensitive  film  having  a  thermosensitive  layer transferrable to the image layer of the substrate.  The film is thereafter stripped from the structure and the substrate transferred to a discharge receptacle.

Title: Flexible Corner for Trimming Curved Wall
Inventor: KOENIG JOSEPH M JR
IPC: E04B9/30
Filed: 1995-04-27
Abstract: An improved, elongate, flexible corner for trimming a curved surface, such as a cylindrical surface of a building column, comprises an elongate angle extruded from a relatively hard but flexible, polymeric material and an elongate strip extruded from a relatively soft but pliable, polymeric material.  The elongated angle and the elongate strip are coextruded respectively from polyvinyl chloride having different durometer hardnessess.  The elongate angle has a first, relatively wide, relatively thick flange with a distal edge and a proximal edge and a second, relatively narrow, relatively thin flange with a distal edge and a proximal edge, which is unitary with the proximal edge of the first flange. The second flange extends from the first flange, approximately at a right angle relative to the first flange when the flexible corner is unstressed.  Each of the first and second flanges has an inner surface and an outer surface and the inner surfaces define approximately a right angle relative to each other.  The elongate strip is attached to the elongate angle, along the flexible corner.  The elongate strip is configured so as to have a proximal portion covering the outer surface of the second flange, as far as the outer wall of the first flange, and a distal portion extending beyond the distal edge of the second flange, approximately at a right angle relative to the first flange when the flexible corner is unstressed, and so as to have a recess receiving the second flange.

IPC: A61F13/15
Filed: 1993-11-11
Abstract: 2149144 9410952 PCTABS00032 An absorbent article, particularly a diaper, has a central absorbent unit (1) which is comprised of an elongated absorbent body (2) enclosed between a liquid-permeable inner casing sheet (3) which lies proximal to the wearer in use, and a liquid-impermeable, outer casing sheet (4) which lies distal from the wearer in use.  The absorbent unit is provided along its longitudinal edges (9) with liquid-impermeable folds (6) which are upstanding from the inner casing sheet and which form side-leakage barriers. The article has a side-flap (18) on each side of the absorbent unit (1). The side-flaps (18), optionally with associated edge elastic (21, 23), are produced in the form of rectangular strips (10) completely separated from the absorbent unit (1) and are thereafter jointed thereto. A longitudinally extending edge-part (13) of each strip (10) is suitably folded double and the backwardly folded part (19) is joined to the outer casing sheet (3a, 4b or 4) of the absorbent unit (1) along a curved fastening line (21). When the diaper is to be used, the side-flaps (18) are pulled-out laterally, the length of this extension, and therewith the width of the resulting side-flaps (18), being dependent on the curved shape of the fastening line (21). It is therewith possible to produce a curved outer contour (16) of the diaper for conforming to the wearer's legs with side-flaps (18) which originally have straight edges (11, 12). The material from which the side-flaps (18) are made can be chosen quite independently of the inner and the outer casing sheets (3, 4), so as to avoid irritation of the wearer's skin while still fitting closely to the wearer's legs.
