Abstract: An apparatus for transferring a relatively flat object (58) from a work station along a transfer path includes an upper tooling (32) within the work station for locating the object in a ready position by causing an upper surface of the object to adhere to the tooling. The object is thus unsupported along its lower surface. A manifold (70) forming an orifice is located adjacent to and directed toward the ready position, and is connected to a source of compressed gas. A valve (71) initiates and discontinues flow of pressurized gas through the orifice. A control system controls the valve to direct a stream of pressurized gas through the orifice when an object is located in the ready position, thereby causing the transfer of the object in free flight from the work station.

Abstract: In this novel process, multinuclear aromatic polyamines are prepared by reaction of aniline with formaldehyde in the presence of water and acid catalysts, if desired after preparation of an aminal precursor, work up of the resulting reaction mixture by extraction using an aniline-containing hydrophobic solvent, separation of the resulting organic phase by distillation into (i) a distillate consisting of aniline-containing solvent and (ii) a distillation residue consisting of the process product, and recycling of the aqueous phase formed in the extraction by reusing the catalyst contained therein. The procedure is such that a) the reaction is carried out in two phases in the presence of a hydrophobic solvent, b) the two-phase reaction mixture is separated into an aqueous and an organic phase, c) the organic phase formed in the phase separator is separated separately or together with the organic phase leaving the extraction stage by distillation into an aniline-containing solvent and a distillation residue consisting of the process product, and d) the distillate according to c) is separated into two individual streams, one of which is recycled into the initial step of the process and the other is used in the extraction stage for extracting the aqueous phase.

Abstract: The notching tongs for crimping end caps, cable shoes and connectors on electrical conductors has mutually crossing tong limbs (1, 2) of flat spring steel which are connected to one another at the crossing point via a hinge bolt (3). The two limbs (1 and 2) of the tongs each consist of two identical shells (1', 2') arranged parallel to one another. To ensure that they spring back when they are pressed beyond the crimping position, each of the shells is provided with a longitudinal slot (9) which extends via the hole for the hinge bolt, originating from the edge on the jaw side. When the tongs are closed, the slots 8 are aligned in the central longitudinal plane of the tongs. The slots permit the handle sections (1b) and (2b) to spring back when they are pressed beyond the crimping position in order to disengage the latch (11) with the toothed catch projection (12) when the tongs are pressed beyond the crimping position. <IMAGE>

Abstract: A record in which a color is represented on a record medium at a selected gray scale level is created by resolving an addressable area of the record medium into a square array of addressable record locations and organizing the record loca­tions into a plurality of groups each containing a 4 x 4 array of record locations. The groups are organized into a plurality of dither cells each containing a 4 x 4 array of groups, whereby each dither cell contains 256 addressable record locations. An [i+(j x 16)]th gray scale level is established within a selected area of the record medium, where i is an integer in the range from zero to 16, j is an integer in the range from zero to 16 and [i+(j x 16)] is an integer in the range from zero to 255, by ad­dressing j record locations in each group of each dither cell within the selected area and addressing one additional record location in each of the i groups of each dither cell within the selected area, the j addressed locations in each group being substantially contiguous and being in substantially the same positions in their group as the j addressed loca­tions in each other group, and the i groups which contain an additional addressed record locations being distributed substantially uniformly over the dither cell.

Abstract: The present invention discloses a new class of calcium chelating compounds which have a decreased affinity for calcium following illumination. These new compounds contain a photolabile nitrobenzyl derivative coupled to a tetracarboxylate Ca²⁺ chelating parent compound having the octacoordinate chelating groups characteristic of EGTA or BAPTA. However unlike EGTA or BAPTA-like compounds, in which the two halves of the chelator are linked by a simple 1,2-ethanediyl moiety, the compounds of the present invention modify the stereochemical conformation of this linkage by adding bulky substituents or incorporating the linkage into a carbocyclic or heterocyclic ring. In a first form, the new compounds are comprised of a BAPTA-like chelator coupled to a single 2-nitrobenzyl derivative, which in turn is a photochemical precursor of a 2-nitrosobenzophenone. In a second form, the new compounds are comprised of a BAPTA-like chelator coupled to two 2-nitrobenzyl derivatives, themselves photochemical precursors of the related 2-nitrosobenzophenones.

Abstract: A novel tridentate conjugate has three chemical moieties, or tridentate members, attached through an appropriate spacer moiety. At least two of the tridentate members are relatively small molecules, usually less than about 7,000 Daltons in size. The particular appropriate spacer moiety selected for a tridentate imparts certain steric properties to the tridentate conjugate. In one embodiment, the binding of a macromolecular specific binding partner to one of the tridentate members sterically inhibits the binding of a different macromolecule to another tridentate member. In another embodiment, the binding of a first tridentate member to a macromolecule restricts the subsequent binding of a second tridentate member to a proximate location on the same macromolecule.
