As a preliminary stage in manufacturing a lens or lens part for an objective, in particular a projection objective for a microlithography projection system, an optical blank is made from a crystal material. As a first step in manufacturing the optical blank, one determines the orientation of a first crystallographic direction that is defined in the crystallographic structure of the material. The material is then machined into an optical blank so that the first crystallographic direction is subst...

A fiber-made surface fastener having on its back a covering of soft fiber yarns excellent in softness and in a function and durability as a surface fastener and including a multiplicity of engaging elements woven or knitted simultaneously with weaving or knitting of a substrate woven or knitted fabric (10) and projecting from a surface of the same woven or knitted fabric (10). Warp yarns (11 to 17, 111, 114) of the substrate woven or knitted fabric (10) contain finished yarns (15, 114) partially...

Described is a method for the production of metal oxides by flame spray pyrolysis, in particular mixed metal oxides such as ceria/zirconia, and metal oxides obtainable by said method. Due to high enthalpy solvents with a high carboxylic acid content said metal oxides have improved properties. For example ceria/zirconia has excellent oxygen storage capacity at high zirconium levels up to more than 80% of whole metal content.

Habitation cells are prefabricated and comprise a floor with U-shaped irons at the corner. The cell in place on a floor rests on these irons.

A bag for placing in a cylindrical or barrel-shaped container includes front and rear panels (11, 12) between which side panels (13, 14) folded double are positioned. The base of the bag runs to a point along edges (17, 18). When the bag is unfolded this is able to come into contact with the inside wall of a cylindrical or barrel-shaped container having a round base and neck without significant stresses. As a result high material stresses are avoided and the barrier properties of the bag are ret...

A resin-made gearing apparatus that includes a configuration in which only one tooth flank side of each tooth in one of a pair of gears is provided with an overhang section that is disposed on at least one end portion in a tooth width direction, and overhangs diagonally from the one tooth flank side toward the adjacent tooth side; an end portion in a tooth width direction of each tooth in the other gear is provided with a lightening section that is disposed in a tooth flank of each tooth on an e...

It is composed of a framework made up entirely of pieces of recycled plastic that basically comprises bearers (1-2), distributed in several sectors along the whole length of the greenhouse and made up of sections (3-4) that are fitted to one another by means of linear connectors (5) which engage on lugs (12-16) and which are in turn joined by means of cross connectors (8) that engage on lugs (17) provided on horizontal sections (6) making up horizontal cross members (7) which brace the framework...

A pallet made of synthetic resin and including four corner posts, intermediate posts therebetween, a center post, with hollow edge boards connecting the corner posts and the intermediate posts, and hollow deck boards connecting the intermediate posts and the center post. The pallet is formed from four identical complementary elements combined along two crossed division lines, each element provided with the above described hollow edge boards and hollow deck boards, each of which have flat walls p...

The handcuff assembly includes a bow pivotally connected to a cheek plate frame assembly which includes a unitized frame that is die stamped from a metal plate and which is overmolded with a polymer overmold. The bow and arcuate cheek arms engage a wrist of a person to be restrained with an envelope of the bow being defined by a conic path with an increasing arc. The bow and cheek arms have rounded inner edge surfaces. The cheek arms have reinforcing ribs. The molded polymer covering surrounding...

The object of this invention is a packaging comprising a cover, a bottom part with recesses and an insert for subdividing the bottom part into receptacle cells for holding round or egg-shaped packaged materials, manufactured from essentially flat blanks and a method of uprighting the insert.
