Abstract: The present invention relates to a sodium-sulfur electric cell structure having a specific joint between a cathode tube and an anode tube. The cathode (3) and anode (2) tubes are each made of an iron-nickel base alloy and are jointed to each other through the medium of a ceramic ring (4) and an aluminum insert (5) provided on both sides of the ceramic ring. A chromium or chromium-rich layer is formed at the jointing boundary between the insert (5) and each tube (2,3). The sodium-sulfur electric cell having such a structure eliminates a problem on the occurrence of cracking, improves the airtightness and enables the production of large-sized electric cells.

Abstract: Scrambling and descrambling systems utilizing jamming signals provide improved pictures with minimal distortion due to ghosts and artifacts. The television signal is combined with a jamming signal or signals located preferably in the vestigial sideband (VSB) of the modulated picture carrier and at about a null in the spectrum of the modulation of the picture carrier by the horizontal sync. The jamming signal or signals also preferably are placed between the harmonic components of the horizontal sync which define the horizontal sync spectrum and at frequencies which comply with governmental regulations respecting frequency locations of strong signals for CATV purposes. The jamming signals are generated by phase locking to the horizontal sync signals of the television signals or to a submultiple of the horizontal sync frequency. Artifacts are further reduced by preemphasis of the transmitted television signal in the sideband opposite to that in which the jamming signal or signals are located and spaced by an equal frequency increment for the location of the jamming signal energy. In order to extract the jamming signal, so as to descramble the television signal for reproduction in the subscriber's television receiver, a network including at least one surface acoustic wave (SAW) resonator device is embedded in an all-pass network which allows essentially lossless transmission of the television signal spectrum, except   for the jamming signal energy and enables that energy to be located close to (e.g., approximately 228 KHz) from) the picture carrier in the VSB for enhanced security.

Abstract: A system for storing electrical energy in the form of triple-point CO₂ and then using such stored energy plus heat to generate electrical power. A reservoir (11) of carbon dioxide liquid at about the triple point is created in an insulated vessel. Liquid carbon dioxide is withdrawn and pumped to a high pressure (47,15), which high pressure carbon dioxide is heated (19,21) and expanded (23) to create rotary power which generates electrical power (25). The discharge stream from the expander is cooled (19,47) and returned to the vessel (11) where carbon dioxide vapor is condensed by melting solid carbon dioxide. 
     A fuel-fired gas turbine (27) connected to an electrical power generator (29) can be used to heat the high pressure carbon dioxide (21), and an ambient air stream flowing toward the gas turbine can be cooled (48) by giving up heat to the high pressure carbon dioxide stream. 
     The returning expanded carbon dioxide stream can be returned to a separate auxiliary vessel (63), and liquid carbon dioxide pumped from such auxiliary vessel (63) to a main vessel (11) wherein solid carbon dioxide is formed and then transferred to the auxiliary vessel.

Abstract: Superconducting thin films of RE₁Ba₂Cu₄O z , where RE is a rare earth metal chosen from the group consisting of yttrium, ytterbium, and europium, are produced in a non-vacuum environment using metallo-organic deposition techniques. A metallo-­organic solution comprising the neodecanoates of the rare earth metal, barium, and copper is formed and spun on a single crystal substrate of strontium titanate to form a film thereon. The metallo-organic film is heated in an air environment at a temperature sufficient to decompose the neodecanoates, about 500°C, and then annealed to promote recrystallization and grain growth of the resulting metal oxides. The annealing step is preferably accomplished using rapid thermal annealing techniques wherein the material is uniformly and rapidly heated to an appropriate temperature for an amount of time of up to about 2 minutes. The resulting films of material exhibit superconductive characteristics at elevated temperatures relative to the temperature of liquid nitrogen.

Abstract: Logical connections between processes (PA1, ..., PFn) and bus managers interfacing bus units (50, 52) to an I/O bus (54) are assigned to connection groups (86, 88) for management by the bus managers. Each bus unit has its own connection groups for the logical connections. Bus unit resources are assigned to each connection group based on performance factors, and a series of bus unit messages are used to control the flow of work so that a group which has no more resources will not accept further work requests. The originator of the work requests will resequence rejected work requests and resend them when the connection group has freed up resources. A further mechanism is provided to facilitate work consistent with the server driven architecture when bus units do not have adequate DMA capabilities. Two ways of reversing control of transfer of work requests and data so that the server need not have master DMA capability are presented. Management of storage in a remote processor is used to transfer work and its associated data into storage accessible by a bus unit with slave DMA capability. The slave DMA bus unit then transfers the information into storage is manages. In another way of reversing the flow, a bus unit message is used to make the original server a requestor. The bus unit message contains information which varies the request sent by the requestor. In this manner, the server, which was the original requestor transfers information using its master DMA capability flow.

Abstract: A method and apparatus for continually obtaining accurate opacity monitor readings of an exhaust gas stream (15) are disclosed. An opacity monitor having a transmit­ter (10) and a receiver (13) is shielded from an exhaust stack (16) environment by two scratch-resistant windows (19, 20), which are intermittently cleaned by remote control using a spray of a volatile nonflammable cleaning solvent (28) and a reciprocating resilient wiper arm (22). This cleaning may be performed for a period of about twenty seconds each time. An accurate opacity monitor reading is obtained by directing a light beam (34) across the stack (16) from the transmitter (10) via first window (19) through the exhaust gas stream (15) to the receiver (13) via second window (20). The reading is obtained during about the next ten seconds. In lieu of the wiper, a reciprocating brush (40) may be used.

Abstract: The invention proposes a bipolar transistor (B2) as a protection device against electric overvoltages for integrated circuits in the installed and uninstalled state, which bipolar transistor is arranged so as to be isolated from the integrated circuit. The base connection (B) of the bipolar transistor (B2) is connected to a first voltage (Vss), the collector connection (C) to a second voltage (VDD) and the emitter connection (E) to the input or output (E/A) to be protected. The specified interconnection of the bipolar transistor (B2) and also its isolation with respect to the semiconductor substrate (Psub) minimises substrate currents which occur during operation and consequently eliminates the risk of a "latch-up".
