Abstract: A method of managing care requests in a social care network is described. The method includes associating, by a care request processor, a plurality of individuals as members of the social care network. The care request processor receives care request information for an individual member of the social care network and generates and manages tasks based in part on the care request information. Embodiments further include providing contextual advertisements within the network, providing access to personal health information and translating between clinical language and natural language as needed.

Abstract: A first process is provided for forming a stack of leaves for use in a leaf seal which effects a seal between two components. Corresponding processes are provided for forming a leaf-spacer pair and then for forming a stack of leaves from such pairs. Each leaf of the stack has a leaf section which maintains wiping contact with one of the components and a root section which is fixed relative to the other component and from which the leaf section extends. The stack includes a plurality of spacers which interpose between the root sections.

Abstract: In order to provide simpler manufacture and lift up and blow down control, leaf elements are provided which have profile edges arranged to associate with each other in order to create a ring carousel, either about the front or rear edge of a leaf seal arrangement. In such circumstances gas flow through the leaf seal arrangement encounters the profile edge in order to adjust leaf section position for appropriate sealing efficiency.

Abstract: Seal arrangements utilizing leaf seal elements are susceptible to excessive wear at their tips due to blow-down pressures. When the seal element is forced against a rear surface across the pressure differential between the sides A, B of an arrangement. These tips may be forced into engagement with the rotating shaft and therefore wear on the shaft as well as at the tip occurs. By providing channels which extend laterally across more than one seal element pressure relief is maintained and therefore a limit to blow-down force maintained. The channels also extend radially and normally on a low pressure side of the seal arrangement.

Abstract: Leaf seal arrangements 1 are known in which a number of leaf seals 2 are presented in a housing 3 in order to create a seal relative to a rotating surface 4. Conventional arrangements 21 have the leaf seals 2 aligned with an axis of rotation for the rotating surface 4, there is symmetrical lift up and blow down of a tip end 5 relative to the surface 4. In such circumstances the arrangement 1 is dependent upon the seal 2 stiffness to achieve designed operational performance. By presenting leaf seals 22 at an askew angle relative to an axis of rotation RR asymmetric deflection is achieved between an inlet side 30 and an exit side 31 such that the inlet and exit flow areas change and therefore lift up/blow down forces can be controlled to achieve a more optimal positioning of a tip end 25 relative to a rotating surface for operational performance with reduced risk of wear upon the leaf seals 22.

Abstract: The benefits of leaf seals with respect to providing sealing in gas turbine engines is well known but wide scale applicability is hindered by the costs and manpower necessary for assembly of leaf seals. By utilising a concertina fold of a band or strip 50, 80 in which leaf seal elements 51, 52 are defined with leaves seal sections 52, 82 and spacers 53, 83 defined at tilt angles appropriate for the eventual lay angle in a leaf seal assembly more automated manufacture of leaf seal assemblies is achieved. The means by which the leaf seal sections 51, 81 are formed ensures that the spacers 53, 83 have a thickness greater than the leaf seal element 82a and generally side portions are provided with folding sections 56, 86 which are sacrificially removed during forming of leaf tufts 140 for final assembly within leaf seal assembly 1.

Abstract: A hardmetal drill bit button is restored by forming its head to a chisel shape. Various chisel shapes and a machine for the purpose are disclosed. Also disclosed are various kinds of grinding wheels for the purpose, and a method and means for simultaneously dressing the steel of the bit body.

Abstract: A new method for fabricating a semiconductor device, e.g., a MOS or MES IC, as well as the resulting device, are disclosed. In accordance with the new method, a semiconductor device is formed, at least in part, by forming a material region which includes metal, e.g., elemental metal or a metal-containing compound, on a semiconductor substrate. One or more dopants are implanted into the material region, and the substrate is heated in order to diffuse the dopants out of the material region and into the substrate, thus forming a dopant-diffused substrate region, e.g., a source or drain. Significantly, the new method involves implant conditions which yield a material region-to-substrate specific contact resistance equal to or less than about 10.sup.-6 .OMEGA.-cm.sup.2. In addition, the new method involves heating temperatures and heating times which yield a dopant-diffused substrate region having a depth, relative to the top of the material region, equal to or less than about 0.2 micrometers.

Abstract: An attachment for a portable jig saw permits a concurrent use of a pair of jig saw blades. The blades are each attached to a holder by threaded fasteners, while the holder is then threadably attached to the jig saw. The spacing between the blades may be varied by an adjustment of the holder.

Abstract: It has been found that stress in X-ray transparent films used to form masks for X-ray lithography also cause distortions of the film and of the high-resolution X-ray-absorptive pattern formed thereon. A method is disclosed which anneals boron nitride films for use in X-ray masks in such a way as to control stress.

Abstract: A deflection wedge is positioned in a long horizontal drill hole by securing it with a shear pin to an extension on a drill string. The extension is turned independently of the drill string to enable a droparm mechanism to actuate a trigger which stops rotation at a predetermined orientation. Rotation is effected by means of a rifle bar mechanism. The rifle bar presses against the bottom of the hole to cause rotation and the trigger declutches the rifle nut when the droparm drops.
