  • Patent number: 5195031
    Abstract: A video communication trading system network includes a plurality of subscriber keystations (410,412) at least one of which employs a conversation analyzing keystation terminal controller (400,400a) for parsing a trading conversation between designated keystations (98a,602) for automatically providing trading conversation context sensitive trading data messages, such as trading conversation textual message prompts based on real time trading conversation analysis. The trading system network includes a message switching interface (300) for routing trading conversational messages throughout the network. The context sensitive prompt messages are analysis driven to provide prompt messages based on the analyzed dialogue as the conversation progresses. These prompts can be manually overridden by the user. The system also provides for dynamic creation of a ticket (416,404), which is also displayed, as the conversation progresses based on the real time analysis of the conversation.

  • Patent number: 5187543
    Abstract: A linear displacement interferometer system employs glass wedge prisms (71, 73, 75, 76) diposed about the interferometer axis of symmetry to refract the beams (51A, 55A) produced by the interferometer onto a single area (72, 86) approximately the size of the interferometer beam. If only one spot is produced on each of the stage and reference mirrors (72, 86), then any ambiguity concerning the beams (51B, 55B) is eliminated. In the preferred system, the stage (72) and standard (86) mirrors are located where the refracted beam crosses an interferometer axis of symmetry (80).

  • Patent number: 5147655
    Abstract: An oral composition which is adapted to be dispersed in an aqueous carrier substantially immediately prior to administration comprises a multiplicity of particles comprising an active substance, the particles being combined with one or more gelling or swelling agents capable of forming a viscous medium around the particles in an aqueous carrier as well as being provided with a masking surface layer when dispersed in the aqueous carrier. This serves to mask uneven surfaces on the particles and prevent them from adhering to oral mucosa when the composition is ingested and thus makes it easier to administer large dosages of an active substance. The masking surface layer is preferably provided by an increased viscosity of the viscous medium in the immediate vicinity of the particles relative to the viscosity of the surrounding aqueous carrier. A ready-to-use composition is prepared by mixing the composition with an aqueous carrier substantially immediately prior to administration of the composition.

  • Patent number: 5130764
    Abstract: A technique utilizing conventional photolithography to manufacture GaAs MESFET devices having sub-micrometric gate and variable length recessed channel. The structure of these devices consists of two photopolymeric layers separated by a metal interface. The upper, stencil layer sets the aperture of the submicrometric gate. The lower planarizing layer defines the recessed channel, through the metal interface, which acts as a template. The length of such channel may be varied through suitable choice of exposure time of the planarizing photopolymer. By adopting such multilayer structures it is possible to obtain gate lengths of .about.b .mu.m and recessed channel lengths form 0.8 to 3 .mu.m, with a process yield typically better than 90%, simultaneously. Furthermore, by using a thicker planarizing layer in this structure it is possible to obtain a relatively thick metal deposit (typically about 0.8 .mu.m), such as a Ti/Pt/Au overlayer over ohmic contacts and gate pads.

  • Patent number: 5083402
    Abstract: Conventional industrial pressure blasting apparatus is modified to allow a controlled pressure on the blast pot that is greater than the pressure on the line where less aggressive abrasive media and air are mixed for conveying the mixture to the nozzle and then to the workpiece. A media control device, with a fixed but readily variable area, is placed between the blast pot and the media/air mixing line to meter the media flow and maintain a positive pressure differential between the blast pot and the line. Adjusting the pressure differential allows control of the weight ratio of the media-to-air flow to between about 0.05 to 0.25.

A media control device, with a fixed but readily variable area, is placed between the blast pot and the media/air mixing line to meter the media flow and maintain the pressure differential between the blast pot and the line. This allows control of the media flow when low flow rates, below about 10 pounds per minute, are required.
