Inventor: BOGART FRANK J
IPC: H04M3/42
Filed: 1992-08-20
Abstract: Tone treatment given to callers by an originating switching system (10) during dialing may be customized in a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the network numbering plan. The syntax definitions include definitions (312) of individual symbol strings and their associated tones (336), if any. Associations of tones with symbol strings are administratively reprogrammable to change the specified tone treatment. Following dialing and identification (340) of an individual symbol string, a caller is immediately fed back (906) the string's associated tone, if any. A caller is thus immediately advised during dialing of successful or unsuccessful input of avalid symbol string, and is selectively prompted for input of another string. Caller-perceivable feedback signals other than tones may be used with equal effect.

Title: Metal forms for insulated foundations
Inventor: ANNAND CHARLES A
IPC: E04G17/00
Filed: 1992-11-23
Abstract: ABSTRACT: These metal forms for insulated foundations are designed primarily for insulated house basement wall construction.  The steel forms are designed to be positioned by means of a crane or by manual means and are designed with reusable top and bottom wall ties and a reusable center wall tie which is placed across the wall at the half way point of the wall form.  These metal forms use a Horizontal Concept of form panels where the through-wall ties are placed in horizontal lines rather than in the conventional vertical lines of the presently used foundation form systems for house wall construction.          These forms use this Horizontal Concept for the metal form panels as well as for the insulation wall panels which are placed in the center of the concrete wall system.  The metal forms are designed with a top and bottom section with a horizontal joint at the half way point where the forms can be separated in order to allow the intermediate wall ties to be placed in the wall system.  This Horizontal Concept also allows the walls to be insulated with horizontal insulation panels which then can be held in place and located more efficiently by this horizontal panel concept than with the now presently used vertical wall form panel concepts.  The forms are constructed in metal and are made in top and bottom units in order that their weight will not be excessive for manual handling of the form panels, however, if the panels are pin connected, they are also designed that they can be handled in complete panel systems or in Gang Forms by means of cranes or a specially designed crane for this system.

Abstract: 2086333 9200043 PCTABS00010 A body implantable stent (16) consists of two or more generally tubular, coaxial and slidably connected stent segments (20, 22).  Each segment (20, 22) is of open weave construction, formed of multiple braided, helically wound strands of resilient material. The stent is elastically deformed to a reduced radius when deployed.  When released after positioning, the stent (16) self-expands radially and each segment (20, 22) contracts in the axial direction.  To preserve a consistent length of the stent (16) the axially outward and non-overlapping portions (30, 32) of the stent (16) can be designed for secure fixation to the tissue, for example as radially outward flares (34, 36). Alternative approaches to maintain axial length include the addition of reinforcing filaments (62) near the stent opposite ends to increase the restoring force, the provision of fixation hooks (70) at opposite ends of the stent, and securing an elongate, axially directed, flexible and inextensible wire (104) to the opposite ends of the stent.

Abstract: A porous and spherical silica is recovered in high yields from a neutralized product of an alkali silicate obtained by using an acrylamide type polymer as a coagulation growing agent, and the above silica is reacted as a precursor with a metal compound of the Group II of periodic table in an aqueous medium to obtain amorphous or fine, laminar and crystalline porous and spherical silica or silicate granules having a high degree of true sphericality, a symmetrical grain size distribution and a refractive index over a range of from 1.4 to 1.7. The porous and spherical granules have a primary grain diameter of 0.3 to 30 µm as observed through an electron microscope, have an apparent specific gravity of from 0.05 to 0.5 g/ml, and are cheaply obtained in high yields, and can hence be used as a filler for various paints and resins.  In particularly, the granules excellently disperse in the resins, have a refractive index close to those of the resins, are not crushed during the kneading with resins or extrusion, or do not damage the apparatus.  The films obtained by using these granules exhibit very excellent transparency, anti-blocking property and scar resistance.  Moreover, the porous and spherical zinc phillosilicate type granules having fine grain sizes and symmetrical grain size distributions, are excellent in their odor scavenging property and sweat controlling property.

Inventor: SCHABERT HANS-PETER
IPC: F16K31/04
Filed: 1991-07-24
Abstract: In order to protect a spindle (2) rotated in a fitting by a spindle nut (6) rotating in a housing (4), the invention calls for a braking device for the spindle nut (6). When a given reference force is exceeded, two facing friction surfaces (11, 13) are pressed towards each other against the spindle (2) to exert a braking force. One friction surface (13) is rotationally secured with respect to the spindle nut (6), while the other friction surface (11) is rotationally secured with respect to the housing (4). The invention calls for the spindle nut (6) to be spring-mounted by a spring washer assembly (50, 51) in at least one longitudinal direction, the braking force acting through this assembly on an intermediate radius (ro) relative to the width (r1 - r2) of the assembly. The fraction of the total spindle force which acts as a braking force is thus increased.
