Title: Method of removing alkali material from hot gas
IPC: H02K44/08
Filed: 1964-09-30
Abstract: Alkali material (i.e. pure alkali metal, alkali metal salts and hydroxide) is removed from a gaseous mixture of the alkali material and coal combustion products heated to at least 3000 DEG  F. (the alkali material having been introduced into the mixture to increase its electrical conductivity) by condensing and removing substantially all of the non-combustible matter other than the alkali material at a temperature greater than that at which the alkali material is substantially soluble in the non-combustible matter and less than the condensation temperature of the non-combustible matter, i.e. 3000-4000 DEG  F. and then cooling the resulting gaseous mixture to condense the alkali material, which is removed from the cooled mixture. The mixture at a temperature greater than that at which the alkali material is soluble in the non-combustible matter, i.e. at 3500-4000 DEG  F., is passed through a separator wherein the temperature at the gas outlet of the separator is 3500-3000 DEG  F. The condensation and removal of non-combustible matter may be effected after the mixture has passed between opposed electrodes disposed in and normal to a magnetic field in a magnetohydrodynamic device and then through a diffuser zone to decrease the velocity of the gas.  The condensed alkali material may be reintroduced into the mixture at the point of combustion of the coal.

Title: Bus controller for digital computer system
IPC: G06F13/368
Filed: 1974-09-23
Abstract: 1445219 Digital computing systems RAYTHEON CO 23 Sept 1974 [26 Oct 1973] 41331/74 Heading G4A The system includes a number of major units, (e.g. processors, peripherals or memories) connected to a common bus for the interchange of data. Each unit is associated with a respective bus controller, the controllers being serially connected to form a closed loop. The major units are synchronized by pulses from a common clock source, and each can pass a block of data to the bus only during the interval between adjacent clock pulses. Each bus controller responds to the state of the preceding controller and to a control signal from the associated major unit so that only one of the controllers produces a gating signal during a given clock interval. The gating signal enables an AND gate in an associated transmission controller connected between the major unit and the bus to permit the data to be transmitted. The major units may be connected to each of two or more buses, in which case each bus controller includes a corresponding number of subcontrollers. The circuit (Fig. 2, not shown) of the bus controller is so arranged that if it receives a signal from the preceding controller indicating that the first bus, bus A, is available and a signal from the major unit that there is data for transmission it generates a gating signal to transmit the data on bus A and generates a signal indicating to the next controller that bus A is no longer available. If bus A is not available the controller may seize bus B, &c., the buses always being seized in the order A, B, C... When control signals from the major unit indicate that there is no more data for transmission the controller passes a signal to the next indicating that the bus is available. By impressing a disabling signal on the controller it can be prevented from seizing any bus, so allowing the major unit to be removed. Each transmission controller (Figs. 3A-3C, not shown) includes a number of registers connected in cascade. When a parallel-bit data block for transmission is received from the associated major unit it passes to a first of these registers and is also transmitted if the gating signal is present. Subsequent clock pulses transfer the data to successive registers. At the receiving unit (Fig. 4, not shown) to which the data is addressed the data is checked for parity error and an acknowledgment/error signal returned to the transmission controller. If error was detected this signal prevents further transmission of data from the major unit by disabling the AND gate in the transmission controller; such data is, however, passed to the registers. The register holding the data found to be faulty is then read out and the data retransmitted: the receiving unit does not provide an error signal in respect of retransmitted data.
