Title: Multimedia system
Inventor: GARLAND J DAVID
IPC: H04N7/173
Filed: 1994-10-17
Granted: 1999-09-07
Abstract: The provisioning of a multimedia application is enhanced by using a communications protocol which defines a number of different functions and which allows a multimedia application to be segmented into a plurality of logical blocks such that a user may enter a request characterizing one such function and, in response thereto, the system performs the function with respect to a particular one of the logical blocks. The underlying multimedia system is also enhanced by arranging it so that an application provider may interact with the system via a telecommunications network for the purpose of, for example, storing the application thereon andlor "debugging" the stored application.

Abstract: A stationary, formed metal cap covers the bearing assembly of the rotatable firming wheel to protect the bearings against the ingress of mud, residue and moisture. A smooth, convex, exposed outer surface on the cap discourages the accumulation of residue and mud between the rotating wheel and its stationary support arm so as to keep the wheel freely rotating during its rolling movement in the seed trench. A flat, band-like, circular edge around the periphery of the convex surface is received within a circular groove on the face of the wheel to obstruct the ingress of moisture and materials at that location and disposes the marginal periphery of the convex surface in a substantially flush condition with the surface of the wheel to prevent wrapping and accumulation of trash.

Abstract: Mica-wrapped wires for fire-resistant cables have an unusually low degree of overlap in the mica tape wraps, which unexpectably produces a smoother external profile while retaining an acceptable degree of fire protection. Tw o layers of glass-cloth-backed mica tape, preferably with a polymer film overlying the cloth, are preferably applied with their respective (low) overlaps staggered. This smoother wrapping is especially effective when thin (less than 0.8 mm) polymer coatings are to be extruded over the wrapped wire .

Abstract: The invention relates to an active linear induction motor system that has particular advantage with a SAILRAIL? air guided and supported air bearing system. In this case the secondary for the motor is the support rail, which rail can have a convex or a concave operating surface, is electrically conductive, and has ferromagnetic material in close proximity to the operating surface. The primary for the motor is found in a runner which cooperates with the rail and supports the load to be carried in the system. The primary includes a plurality of laterally adjacent, longitudinally extending and articulated ferromagnetic laminations having a longitudinally toothed surface that is transversely arcuate to be complementary to the rail operating surface. Electrical windings are wound about selected groups of teeth of the laminations as a LIM primary. A compliant pad adjacent the laminations is capable of deformation under load and at least partial recovery after load removal. Electrical power is continuously provided to the primary as it moves along the rail and polyphase electrical current is fed to the electrical windings. Cooling fluid is continuously provided to the laminations during operation of the primary. The system also provides pressurized fluid at high velocity into the space between the rail operating surface and the compliant pad, to support the primary member above the operating surface and to provide a minute pressurized magnetic and suspension gap between the primary and secondary members for efficient linear motor operation.
