Abstract: A device coupleable to a remote source of pressurized fluid for producing fluid that can be discharged by the device and thereby propel the device over or through a surface. The device comprises a buoyant hull with one or more fluid communicators for directing fluid flow. A nozzle at the distal end of each fluid communicator creates a fluid discharge from the fluid communicator directed horizontally or at an angle away from horizontal. Flexible tubes connect the fluid communicators to the remote fluid source.

Abstract: A decoder apparatus (200) provides an R,G,B,I video drive signal in a TTL type of format from a received composite video input signal which comprises sync information and displayable information, such as conventional black and white video or a digitally encoded color video signal comprising a sixteen level code for providing sixteen possible color combinations of R,G,B, and I, without loss of bandwidth. The decoder (200) includes means for receiving the composite video input signal (202,10) and restoring it into separate DC restored sync (20a, 20b) and black and white or color video display information (30, 40, 50), both of which may be displayed on the same RGB monitor (107). White reference level signals are dynamically provided from the sampled video information and are used by a flash converter (100) in converting grey scale digitally encoded color video information into the TTL format R,G,B,I type of video signal (60, 70, 80a, 80b, 82a, 82b, 82c) which recovers the origianl R,G,B,I color signal.

Abstract: An encoder (500) encodes a TTL type of R,G,B,I video drive signal into a common multilevel grey scale digitally encoded composite video signal which is transmitted over a single coaxial cable (302). The incoming R,G,B,I bits, such as provided from a color computer (304, 306, 308, 310), are buffered and translated (50a, 50b) from TTL to ECL and fed to a common video digital-to-analog converter (100) along with translated composite sync information (312, 314, 10, 324). A white reference level signal is dynamically derived from the translated sync information (200, 202) and provided to the full height input of the video D/A converter (324, 100) which converts the translated R,G,B,I input into a 16 level multibit grey scale code in a linear function from full intensity white to black, with a seventeenth level being provided in the digitally encoded composite video signal to represent sync information.

Abstract: An auger conveyor assembly for use with a seeder and fertilizer applicator, having tanks which are mounted onto a tool bar frame or carrier such as a field cultivator and wherein the seed tanks are generally positioned adjacent to the hitch of the tool bar frame. The auger conveyor is mounted on the tool bar frame on a member which permits moving the auger from a usable position with the receiving end of the auger adjacent the ground to a transport position. The discharge spout of the auger comprises a flexible tube which can be manipulated for filling the tanks. In transport position the hopper end of the auger is raised above the ground and the entire auger is substantially within the perimeter of the tool bar frame.

Abstract: A seeding device which comprises an attachment that can be placed onto existing tillage implements such as field cultivators and utilizes an air distribution system which permits the transfer of a metered amount of seed into individual air carrying lines, wherein each of said lines deposits seeds immediately behind each shovel or furrow opener on the tillage implement to provide an accurate, and large scale seeding device.
