Abstract: A concrete form spacing fixture comprises a bar type separator having a prescribed length which is provided with a male screw on its end portion, an attachment which is provided with a concave part having an open end and so formed that the open end of the concave part defines an end surface perpendicular to the longitudinal direction of the separator in a state fixed to the end portion of the separator, and a fastening member having a female screw forming part provided with a female screw to be fitted with the male screw of the separator with an outer diameter smaller than an opening diameter of the open end of the concave part of the attachment on an end thereof so that a flange type stop part is provided on a base portion of the female screw forming part.  According to this structure, no male screw is inserted in a hole of a form panel, whereby the form panel is prevented from breakage caused by a bite of a thread.  Consequently, workability in assembling of a concrete form is improved while long-term reuse of the form panel is enabled.

Abstract: A reclosable bag is formed of a first wall and a second wall of a polymeric sheet material joined to form an enclosure with a mouth defined by the wall edges.  The bag has a closure for selectively opening and sealing the mouth.  The closure includes a first and a second mutually interlocking profile, each of which extends along and is bonded to the internal surface of its respective first and second wall.  The first and second mutually interlocking profiles are extruded from a first polymeric resin material, and have a web portion which is bonded to the wall. Coextruded onto the web portions, or applied to the web portions following the extrusion of the strips, is at least one rib of a second polymeric resin material which includes an ultraviolet-light-excitable tracer material.  The second polymeric resin material has a lower melting point than the first polymeric resin material,  and is used to bond the profiles to the sheet material of the walls.  Before such bonding, the ribs appear as discrete lines under ultraviolet light. After a complete bonding, the ribs disappear and are replaced  by  a  smeared brightening  of  the  region between the profiles and the sheet material of the walls.  The appearance of ribs after bonding indicates an unsuccessful bonding operation that could possibly lead to an increase in the occurrence of leaking packages.

Granted: 2006-07-25
Abstract: A multifocal spectacle lens has two optically effective surfaces with powers in the far reference point from -4.0 dpt to +4.0 dpt in the stronger principal section. The spectacle lens has cylinders from 0.0 dpt to 4.0 dpt and an addition of 1.00 dpt to 3.00 dpt. The multifocal area is at least aspherical and can be differentiated continuously at least twice and is not axial symmetrical. The multifocal surface includes a far vision zone, a near vision zone and a progression zone lying between the near and far vision zones. The lens body is configured to incorporate a plurality of features within an elliptical region on the surface of the lens body extending 50 mm measured horizontally and 40 mm measured vertically from the measurement point. These features are all satisfied together within the elliptical region. One of the features is that the near-reference point is at most 21 mm perpendicularly below the far-reference point and displaced by about 2.5 mm toward the edge. Also, a principal viewing line interconnects the far-vision zone and the near-vision zone and the principal viewing line defines a curve swung toward the edge more or less in dependence upon the dioptric power of the far-vision zone and the addition. A predetermined region is formed in the progression zone on both sides of the principal viewing line wherein astigmatic deviation is less than 0.75 dpt.

Abstract: A multi-compartment tank structure for an agricultural air cart is formed in a modular configuration with two, three or more containers operable to carry different supplies of materials to the field. Each container is formed with an interlocking mating wall structure having a pair of spaced apart lobes separated by a curved key portion recessed with respect to the lobes. One container has a convex mating wall configuration interfits with another container having a complementary concave mating wall structure. In the three or more compartment configuration, the interior container is provided with both convex and concave opposing mating walls to cooperate with the adjacent containers. The lobes are formed from a number of planar surface segments. The bends and angles of the lobes coupled with the recessed curved key portion creating a rib provides adequate strength to resist bucking forces even when only one of the containers is utilized with material stored therein. A  ladder is provided adjacent the concave key portions on the interior of the container to provide yet greater resistance to buckling for the concave mating walls.
