Abstract: An apparatus for detailed and sharp self-viewing of the eye including the cornea or surface of the eye comprises a tube-like housing with a diffused light source at one end. The light source projects light through a pin-hole in the center of a baffle in the tube housing towards a convex lens near the other end of the tube housing. When a user holds the tube housing with the convex lens close to his eye, a sharp and detailed image of the eye is projected into the tube and may be viewed by the user. The device is particularly useful for self visual inspection of the condition of the eye cornea, for inspecting contact lenses for air bubbles or debris lying between the lens and the eye, and for inspecting the installation and condition of piggy back lenses.

Abstract: An automotive golf caddy has a high frequency position finder and an ultrasonic position finder. When the caddy is placed in readiness by means of a manual transmitter, it first determines whether it receives ultrasonic signals from the manual transmitter. If that is not the case, it determines by high frequency position finding the direction of the manual transmitter and approaches the transmitter on a straight path at a relatively high speed. When the caddy enters the ultrasonic position finding range, it is automatically switched to ultrasonic position finding, follows the manual transmitter even in curves and continuously determines its distance from the transmitter. When a predetermined minimum distance is reached, the motors of the caddy are switched off. It will only follow the transmitter automatically once again when the transmitter reaches a predetermined distance from the caddy.

Abstract: A breathable diaper, feminine hygiene, or like disposable sanitary product construction having a cloth-like outer surface and including a plurality of materials from the skin-facing side outwardly, a topsheet, a core, an optional barrier, and a backsheet. The topsheet is formed of liquid- and vapor-permeable hydrophilic material, and the core is formed of highly absorbent material disposed outwardly of the topsheet for absorbing liquid received through the topsheet. The core has an inner surface in liquid communication the said topsheet and an outer surface. The optional barrier is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of liquid therethrough while enabling the outward escape of heat and water vapor therethrough. The barrier has a base disposed adjacent the core outer surface.

Abstract: The receptacle is produced in a coextrusion-type blow molding process and consists of a stiff outer receptacle and an easily deformable inner bag which are made from respectively different thermoplastic materials that do not form a welded joint with one another. The bottom weld seam of the inner bag is clamped in a closed bottom web of the outer receptacle. The pressure compensating openings are offset by about 90.degree. with respect to the plane passing through the bottom weld seam and the longitudinal center axis of the receptacle, whereby the inner bag is only contracted at two sides when the receptacle contents is discharged. The negative pressure prevailing inside the inner bag is thereby reduced.

Abstract: A three dimensional sail of one piece construction is made on a rotating roll having a deformable outer surface. The roll is divided into a large number of segments, extending across the width of the roll, with the convex profile of each segment being adjustable. A sail is made on the roll on a continuous basis by applying a first layer of film, deforming the film on the roll, applying adhesive and reinforcing the yarns, and applying a second layer of film to form a 3-D laminate.

Abstract: A liquid acquisition layer is inserted between a porous cover sheet and an absorbent core of an absorbent article such as a disposable diaper. The liquid acquisition layer is made from polymer fibers bonded by an adhesive, with the adhesive rendered insoluble by curing. The cured adhesive has a glass transition temperature in excess of 30.degree. C. and preferably above 37.degree. C., which is normal body temperature. This allows the acquisition to remain resilient and retain void volume when heated by the body or body liquids.

Abstract: An improved reflective mirror for floodlights that can diffuse and reflect a beam of light from a light source in uniform brightness in a given floodlight area is provided. A concave reflecting mirror is provided with an aperture at the axis center of the mirror for inserting a light source such as a bulb, so that the inner periphery of the reflecting mirror is on the side and behind the light source. A plurality of reflectors are formed in the inner periphery of the reflecting mirror in a spiral profile when viewed from the front. The reflectors spiral out from the axis center of the reflecting mirror. Each of the reflectors has a convex or concave profile surface, so that a cross section of the reflective mirror inner periphery surface appears to be ribbed.

Abstract: An absorbent article such as a diaper has an outer layer of a porous fabric and an inner absorbent core. A separator layer of thermally bonded nonwoven fabric is positioned between the outer layer and the core to minimize rewet by liquids. The fibers of the nonwoven fabric of the separator layer have a diameter greater than 28 microns, and at least 5 crimps per extended inch, and the fabric has a porosity of about 90-95%, to provide superior rewet properties.

Abstract: A bait station for containing rat poison contains a housing; at least one opening in the housing for a rat to enter; and a bait position in the housing for locating poisoned bait. A divider is provided between the bait position and each opening to prevent direct access to the bait from the opening, for example by a child. However, there are at least two different routes from the bait position leading to openings. Research has shown that rats, unlike mice, prefer not to eat in a confined space and it is believed that the choice of escape routes offered by the bait station of the invention encourages a rat to eat more of the bait. The bait station may include a hinged lid with locking means to prevent tampering with the bait.

Abstract: An assembly having at least three coaters or separate doctor or blade units, all arranged at a single backing roll coating station is provided. At least two of the coater or blade units can be movably positioned for easy operation and servicing of all three units. Additionally, one or more of the coater units may have doctors or blades, and the coater units with blades or blade unit may each be angularly positioned through a range of blade angles to optimize coating operations.

Abstract: A bottle opener especially devised for removing corks from champagne bottles includes two levers pivotally connected together at their proximal ends and having distal end portions for engagement respectively with the tapered neck of the bottle and under the shoulder on the cork. The lever engaging the neck of the bottle provides a fulcrum from which a significant mechanical advantage can be generated through the compound action of the levers to readily eject the cork from the bottle.

Abstract: A footwear sole comprises a foot-shaped sole of a relatively cushioned, low density polymer foam, with a higher density, harder midfoot shank portion integrally fused within it. The sole may be a unitary footwear sole or may have an outsole or insole adhered thereto. A method of manufacture of the sole comprises forming a polymer foam sole piece, stamping out a portion of the midfoot, forming a shank of higher hardness polymer foam to fit the stamped-out midfoot portion of the sole piece, fitting the shank into the sole piece, and hot compression molding the sole piece and shank to form a unitary, integral sole. The sole of the invention is particularly useful as a sandal sole.

Abstract: A method of and apparatus for minimizing the problem of "fluting" or "corrugating" occuring in printed webs of light weight coated paper printed on both sides with thermosetting ink on heat-set web-offset printing presses resides in spreading the web in its width-wise direction as the printed web exits from the ink drying and heat setting oven of the press and passes over the web cooling chill rolls downstream from the oven, thereby to hold the printed web in a flat and smooth condition until it is cooled and the ink has taken a permanent set. Spreading the web prior to and during cooling allows the inks to thermoset in a flat state because the web is kept flat and free of flutes during thermosetting of the inks. The method and apparatus facilitate operation of the press at higher speeds and with lighter grades of paper than conventional, and provide for increased production efficiencies, lower costs, enhanced print quality, and access to new markets for web-offset printing.

Abstract: A sampling apparatus is characterized by a sampler body having a bore and a forward opening from the bore communicating with the interior of a vessel containing fluidized product in which strands, viscous strings and particles may be entrained. A plunger assembly in the bore is generally cylindrical along a longitudinal axis and has a sample receiver and cutters. The sample receiver is generally tubular and has a plurality of arcuately spaced longitudinal slots extending radially between an outer surface and a hollow interior of the sample receiver, and individual cutters are in facing relationship at opposite ends of the bore. A pneumatic motor reciprocates the plunger in the bore in a forward direction to a sample obtaining position where the sample receiver and cutters are extended at least partly out of the forward bore opening and into the interior of the process line to obtain a sample of fluidized product that flows into and fills the sample receiver passages and hollow interior.

Abstract: A precursor solution for the preparation of metal phosphates is provided. Two components are prepared in which the first is a metal salt dissolved in alcohol, and the second component is phosphorous pentoxide dissolved in alcohol. The two components are mixed and may be applied as a liquid coating to a variety of substrates. The coated substrate is then heated, causing removal of all other components and leaving a layer of pure metal phosphate.
