Filed: 2000-08-23
Abstract: A program distribution system is disclosed for the simultaneous release of a program at a plurality of locations. The locations may include local broadcasters, or even individual devices. A program is modified so that it cannot be played without a release control command and is then copied and distributed either fixed in a media or electronically, (i.e., via private network, the Internet, etc.). At the receiver, the receiver first detects the release control signal (step 114) and then replays the program at will. The program may include a time stamp in which case the receiver cannot replay the program until a control indicative of a current time/date corresponding to the date stamp. Alternatively, the program can be encrypted in which case the release control signal includes the decryption key (step 120). The release control can be broadcast over a TV channel, a radio channel and so on and is preferably imbedded into the signals of the standard TV or radio signals.

Title: Electromagnetically actuated pulley assembly
Inventor: OSTROWSKI RYSZARD
IPC: F16D27/112
Filed: 2000-10-18
Abstract: An electromagnetically actuated power transmitting assembly (8) has a cup shaped pulley structure (30) mounted for rotation about the input shaft (14) of a power driven device (10). The pulley structure (30) has an outer annular driven portion (32) for engaging an endless flexible driving element (12) such that engine driven movement of the driving element rotates the pulley structure (30). The outer annular portion (32) has ferromagnetic material along at least an internal diametrical periphery thereof to allow magnetic flux to flow therethrough. A one-piece flux carrier/mounting structure (60) is formed from ferromagnetic material and has a mounting portion (62) fixedly mounted to the power driven device and an annular flux carrier portion (64) nested within the cup shaped pulley structure (30) to allow the pulley structure to rotate relative to the flux carrier and to allow magnetic flux to flow therebetween. An annular magnetic coil (70) for inducing a field of magnetic flux is fixedly mounted in the carrier portion (64). A selectively movable clutch has a magnetically attractable disc portion (48) and a biasing member (50) biasing the disc portion to a disengaged position. The clutch is mounted such that energizing the coil (70) induces a magnetic flux which overcomes the bias and selectively moves the disc portion from the disengaged position to an engaged position wherein the clutch couples the pulley structure (30) and the input shaft (14) for rotation. De-energizing the coil (70) enables the biasing member (50) to move the disc portion (48) to the disengaged position de-coupling the pulley structure (30) the input shaft (14) to allow the pulley structure (30) to rotate relative thereto.

Title: Refractory coating for components of an aluminum electrolysis cell
Inventor: HUNI JEAN-PAUL R
IPC: C04B41/87
Filed: 2001-02-13
Abstract: A refractory coating is provided for a component of an electrolytic cell for the production of aluminum in which an aqueous slurry is prepared comprising particulate refractory material, e.g. TiB2, dispersed in an aluminum oxalate complex. The slurry is applied as a coating to the surface of the component, e.g. a cathode block, and dried to form a hard refractory surface on the component. The aluminum oxalate complex may be formed in situ during production of the slurry by mixing together oxalic acid and electrostatic precipitator dust comprising aluminum oxide. After the refractory coated component is immersed in a high temperature cryolite bath of an aluminum electrolysis cell, the aluminum oxalate complex is converted to alumina which bonds the refractory particles to the surface of the cell component.

Abstract: A walking stick navigator (WSN) apparatus and process comprises an aided INS (AINS) on a staff assembly that has the "look and feel" of a GPS survey instrument. When GPS is available, the AINS is aided by GPS data, and the surveyor manipulates the staff assembly like a standard GPS survey instrument. When GPS is not available due to signal obstruction, the surveyor manipulates the staff assembly as a walking stick. A switch means coupled to the lower end of the staff assembly provides a stationary interval signal when the surveyor plants and holds the WSN on the ground while walking. An input process is coupled to the AINS output signals and to the stationary interval signals and provides at least one aiding input signal to the AINS for each successive stationary interval, thereby allowing the AINS to control its velocity error and position drift during a GPS outage.
