Abstract: To  prepare  crystalline  sodium  disilicates  having  a laminar structure, a molar ratio of SiO2 to Na2O of (1.9 to 2.1):  1 and a water content of less than 0.3% by weight,  a water glass  solution is  first obtained by reacting sand with sodium hydroxide solution in a molar ratio of SiO2 to Na2O of (2.0 to 2.3) : 1 at temperatures of 180 to 240°C and pressures of 10 to 30 bar. This water glass solution having at least 20% by weight of solids is treated in a spray drier with hot air at 200 to 300°C with the formation of a pulverulent amorphous sodium disilicate having a water content (determined as loss on heating at 700°C)  of 15 to 23% by weight and a bulk density of at least 300 g/l.

Abstract: An apparatus and method for reducing nitrogen oxide emissions from the products of combustion is provided in which a vortex  generator introduces natural gas, or other fluid fuel into the upper portion of a combustion device.  The fuel introduced forms vortices, such as vortex rings, and the fuel reacts with the nitrogen oxide in the combustion products to form ammonia-like compounds, hydrogen cyanide and similar compounds, and nitrogen.  The ammonia and cyanide-like fragments react with additional amounts of nitrogen oxide in the combustion products to form nitrogen gas, water vapor and carbon dioxide.  The vortex rings can be controlled and will maintain their integrity longer than puffs or simple jets of fuel.

Abstract: A magneto-optical recording medium is composed of first through fourth magnetic layers laminated in this order in such a way that an exchange coupling exists between any adjacent layers of the first through fourth magnetic layers so that a magnetization direction can be copied, wherein the first magnetic layer is a memory layer, the second magnetic layer is a writing layer,  the third magnetic layer is a switching  layer,  and  the  fourth magnetic  layer  is  an initializing layer.  Further, respective Curie temperatures Tci satisfy an inequality TC3 < TC1 < TC2  TC4 (i = 1, 2, 3, or 4 indicating an ordinal number of the magnetic layers).          The second magnetic layer exhibits an in-plane magnetization at  room  temperature,   and  exhibits  a  perpendicular magnetization above a predetermined temperature set between the  room  temperature  and  TC3  temperature.    With  this arrangement,  after information is recorded on the memory layer based on the magnetization direction, the interface wall energy can be reduced, and the whole magnetic energy can be made substantially equivalent irrespective of the magnetization condition after recording.   As a result,  a stable  recorded  condition  of  the  memory  layer  can  be achieved.

Title: Systeme non effractif de mesure de la glycemie
Inventor: TARR RANDALL V
IPC: G01N21/65
Filed: 1991-11-12
Abstract: La spectroscopie Raman stimulée est utilisée pour mesurer de façon non invasive la concentration d'une molécule à activité Raman, de préférence le D-glucose, dans l'humeur aqueuse oculaire d'un être vivant. L'appareil et la méthode de l'invention utilisent deux faisceaux laser monochomatiques, un faisceau de pompage et un faisceau de sondage. La puissance du faisceau de pompage est modulée en amplitude, puis les deux faisceaux sont combinés et dirigés dans l'humeur aqueuse oculaire. L'introduction de ces faisceaux laser dans l'humeur aqueuse oculaire provoque une diffusion de Raman et une partie de l'énergie à la fréquence de pompage est transférée à la fréquence de sondage. Les faisceaux de pompage et de sondage sont ensuite détectés à leur sortie de l'humeur aqueuse oculaire. Le faisceau de sondage est filtré, puis est converti en un signal électrique et amplifié. Il est finalement comparé au signal de modulation pour produire un signal électrique représentatif de la concentration de D-glucose dans l'humeur aqueuse oculaire.

Title: Rear-view mirror for vehicles
Inventor: SCHLENKE HUBERT
IPC: B60R1/08
Filed: 1991-09-17
Abstract: ABSTRACT         The invention concerns a vehicle rear-view mirror (1) comprising a plane-mirror section (2) and at least one convex section (3,11) contiguous with the sides of the plane section.  The curvature of the convex side sections is zero at the transition lines (4,12) with the plane-mirror section (2), and increases progressively with increasing arc length (L) from the transition line, the curvature of vertical orthogonal lines of intersection being equal to the curvature of a horizontal reference line (6,6A) at their point of intersection.  The rear-view mirror (1) proposed enables the driver to view both behind and to the side. The mirror (1) is easy to produce since the curvature of the convex side sections (3,11) only departs by a small amount from the plane of the plane-mirror section (2).

Title: Non-furling flag mount
Inventor: ZEITLER RICHARD J
IPC: G09F17/00
Filed: 1993-11-23
Abstract: ABSTRACT OF THE DISCLOSURE            A support assembly for displaying a banner on a non-vertical flagstaff includes a base support for holding the base edge of a banner in fully extended condition,  and an adjustable length deflector element extends at a substantially right angle to the length of the support element, from a point between the ends of the support element.   The free end of the deflector element is attachable to the fabric of the flag at a central point within the flag's outer peripheral borders.  The deflector element is formed of stiffly flexible, resilient material such as piano wire, and it is coupled to the support element by means of a guide bracket that includes a guide channel for resiliently bending the deflector element through a right angle turn.   Dimensions of the guide channel  and  the deflector  element  are selected  so  that the deflector is free to slide telescopically within the channel, for the purpose of slidably varying the length of the portion of the deflector between the free end and the support element.  At the end of the deflector opposite to the free end, a projection extends at a substantially right angle to the length of the deflector to engage a selected one of a plurality of longitudinally spaced-apart mating holes formed along a portion of the length of the support element. When the free end of the deflector has been slidably positioned in a desired location relative to the support element, it can be releasably retained in that position by anchoring the right angle projection in one of the spaced apart holes, relying on the resilience of the normally elongate straight deflector to bias it into the hole until it is manually withdrawn.  By adjusting the distance between the free end of the deflector and the base edge of the flag, the support assembly may be adjusted specifically to various  sizes  of  flags  and  various  support  angles  between horizontal and vertical, to assure that the flag will "drape" naturally while at rest, and will also be relatively free to "wave" naturally under wind forces without risk of furling about the flag staff.

IPC: H04M15/00
Filed: 1993-12-21
Abstract: In a method implemented by a telecommunications switch, a call request is made for a called party having a predetermined directory number. A determination is made if preconnection services are to be provided for the called party, and if such services are to be provided, a service node to provide the services is identified. A further determination is made if the call request is from other than the selected service node. If the call request is not from the selected service node, the call request is routed to the service node for preconnection services. If a call request is from the selected service node, the call is routed to the called party. This permits a selected service node to originate a separate call to the called party so that services can be provided on behalf of the called party in response to a call request made by a calling party. This method allows preconnection services to be provided without the requirement of multiple directory numbers being assigned to the called party.
