  • Patent number: 4531184
    Abstract: A video conversational data communication network (30) in which subscribers (34, 36) may conduct conversational video textual data communications with one or more keystations (70, 602, 98) in the network (30). Each keystation (70, 602, 98) is associated with a keystation terminal controller interface (68, 96, 600) which is in turn connected to a message switching node (32) for routing calls throughout the network (30). The keystation controller interface (68, 96, 600) locally stores (304, 306) video conversational textual data for its associated keystations (70, 82, 84, 98, 100, 602) and enables two different designated keystations to conduct two different video conversations with a common keystation in a split screen display (76). The split screen display (76) may also be used to display retrievable data from a data base (50, 52) for simultaneous display (76) along with a video conversation.

  • Patent number: 4527341
    Abstract: An angle determinator comprises four hingedly interconnected links. These links form jointly a parallelogram having its apexes constructed as pivot joints. At one of the apexes of the parallelogram the links are rotatably connected to a bar which is provided with a scale. Along this scale that apex of the parallelogram which is opposite to said one apex is displaceable together with a pointer cooperating with said scale. To make possible quick and handy determination not only of such "concave" or "open" angles as are defined by two planes, e.g. a floor and a wall or a wall and a ceiling, but also of "convex" or "solid" angles, i.e.

  • Patent number: 4519402
    Abstract: A syringe for collecting a sample of blood or another liquid comprises a syringe cylinder and a piston arranged displaceably therein. One or more axially extending recesses are formed in the inner wall of the syringe cylinder axially spaced from the inner end thereof. The recess or recesses contain a material which is pervious to gas and impervious to liquid, such as a hydrophobic material, a hydrophilic material with capillary effect, or a material which swells when contacted by liquid. The sample collecting chamber within the cylinder may be vented to the atmosphere by placing the piston in the recessed area of the cylinder. Arterial blood may then pass into the syringe under arterial blood pressure, and the flow of blood into the syringe is automatically stopped when the sample collecting chamber of the syringe has been filled, because blood cannot pass the liquid impervious material arranged in the recesses.
