Abstract: Methods and apparatus are disclosed for manufacturing and for providing electrical connectors having maximum shielding from electronic interference. Maximum shielding is inexpensively achieved by manufacturing a shield structure from a single piece of material in a manner yielding individual channels for shielding a contact terminal from the receptacle area to the tail area. Contact terminals are integrated into the shield structure via insertion molding to form a column connector module. A plurality of column connector modules are then inserted into an appropriately formed front housing. As described by the method of this invention, shielding from electronic interference occurs not only between adjacent terminals within a column structure, but also, between terminals contained in adjacent column connector modules.

Abstract: This invention provides a collapsible cubicle 10 having a tubular enclosure 12 of fabric material secured to a pair of resiliently deformable hoops 18 and 20. In use the enclosure 12 is suspendible from a tripod 32 having a telescopically extendible post 36. A sand bag 34 is conveniently provided to stabilise the erected cubicle 10. The enclosure 12 is conveniently stored for transportation by stacking the hoops 18 and 20 on top of each other and manipulating them by means of a twisting action until they form a composite hoop having a lesser diameter than the undeformed hoops.

Abstract: An electromagnetic read/write head carrier structure is disclosed which permits micro-positioning of the heads carried thereon. The carrier structure incorporates a movable subframe mounted in a floating, friction-free condition on the servo arm of a magnetic media drive. Micro-adjustments in head position for use with high-density data formats are accomplished by micro-positioning the head carrier subframe with respect to the servo arm. A voice coil motor is used to induce relative movement between the head carrier subframe and servo arm.

Abstract: The present invention provides cross-linked protein compositions consisting of two or more units of a target-specific protein joined by binding sulfhydryl groups on the target-specific protein units to a sulfhydryl-selective cross-linking agent and a method of making the compositions. These cross-linked protein compositions combine an increase in binding affinity due to the presence of multiple identical binding sites and stability to reduction conditions.

Abstract: A monolithic capacitor having a dielectric ceramic body cosintered with at least two base metal electrodes. The ceramic body is composed of a major ingredient expressed by the formula,(Ba.sub.k-x-y M.sub.x L.sub.y)O.sub.k TiO.sub.2where M is either or both the magnesium and zinc, L is either or both of calcium and magnesium, and k, x and y are numerals in specified ranges. To this major ingredient is added a minor proportion of a first additive ingredient and a second additive ingredient. The first additive ingredient is at least either of dichromium trioxide and aluminum oxide. The second ingredient is a mixture of boric oxide or lithium oxide, silicon dioxide and at least one metal oxide selected from among barium oxide, strontium oxide, calcium oxide, magnesium oxide and zinc oxide. For the fabrication of capacitors the mixture of the above major ingredient and additives in finely divided form are formed into moldings of desired shape and size, each with at least two electrodes buried therein.
