Show moreAn offset carrier longitudinal scan recording and reproducing system for television signals wherein an amplitude modulated video signal is derived from a television receiver and converted to an offset carrier with a full upper sideband and an attenuated vestigial lower sideband. A direct or offset carrier audio signal may be recorded on the same channel with the offset carrier video signal. During monitoring and playback, the offset carrier is heterodyned to a television broadcast frequency or intermediate frequency and coupled into the television receiver. The same receiver may simultaneously supply video I.F. and audio F.M. signals for recording, and monitor offset carrier audio and video signals supplied to the recording head to facilitate recording adjustments.

Show moreA method in a data processing system and apparatus for organizing files or web pages, structured or unstructured, of multiple users stored across one or more server computers into hierarchical file structures on a recordable medium of a data processing system. A user-defined metalabel is assigned to each of the electronic files or web pages. The electronic files or web pages are organized as a function of the metalabels into the hierarchical file structures.

Show moreA nodal apparatus for sending and receiving digital data in multiple data slots has a transmitter for transmitting a request for multiple data slots during a control minislot. A conflict resolution queue representative of nodal apparatus sending substantially simultaneous requests for transmission resulting in a collision in a minislot is maintained and stored in a memory. A transmission queue representative of nodal apparatus that have successfully transmitted in a minislot and can be queued for data slot transmission is stored in memory. The transmitter sends multiple data slots signals comprising multiple slots of digital data in response to the transmission queue. A receiver receives multiple data slots signals comprising digital data. A high priority transmission queue may also be stored in memory.

Show moreA bolt having a shank and integral head has a strip of photoelastic material mounted in the head for manifesting in the form of photoelastic fringes linearly related to bolt tension the bending stresses created in the head during loading of the bolt. To determine the tension in the bolt during or after loading, polarized light is directed toward the photoelastic strip and reflected light from the strip is analyzed to measure fringe order. The fringe order is related to the amount of bending stresses in the head of the bolt by a predetermined calibration curve, the bending stresses being linearly related to bolt tension.

Show moreIonic contact is established and maintained between electrodes and soil in ohmic heating of a subsurface formation for recovery of volatile and semi-volatile materials, such as hazardous waste, hydrocarbon-like materials, and valuable minerals having thermally responsive properties. A compressed, dry sponge is wrapped around an electrode, which is then inserted into a bore hole. A conductive liquid is added to the bore hole, causing the sponge to swell, creating a stable and substantial interface for the flow of heating currents.

Show moreA method of securing against an unauthorized transmission within an authorized multimedia transmission from a sending data processor to a receiving data processor. The method includes altering the network transmission to interfere with the unauthorized transmission and render the unauthorized transmission invalid to the receiving data processor while not noticeably interfering with the streaming multimedia transmission. Monitoring for retransmissions or retransmission requests also serves as an indicator to an administrator that an unauthorized transmission is occurring. The method of this invention can be implemented by network administrator middleboxes such as firewalls.
