Abstract: Abstract of the Disclosure A method of increasing the efficiency of a cyclone-fired boiler which uses high sodium lignite as fuel. The fuel produces ash deposits on heat transfer surfaces within the boilers, and in accordance with the method, powdered limestone is periodically injected into the firebox of the boiler in a quantity and for a time period such that the limestone is heated to a temperature in the range of from about 2200°F to about 2700°F and reacts with ash deposits in the boiler to form layers thereon.  The layers so formed have a higher ash fusion temperature than the unreacted deposits and cause the resulting composite deposit to be more  friable whereby the deposit can be removed using con-ventional soot blower apparatus.

Abstract: COMPRESSED BEAM DIRECTED PARTICLE NUCLEAR ENERGY GENERATOR            ABSTRACT     Atomic nuclei undergo fusion reactions by forming two beams of fusible ions traveling at fusion producng velocities opposed in rotation along spiral paths having common axes (35a), common radii and occupy common space in a reaction zone (22) for fusion producing collisions of ions in one beam with ions in the other beam.     Means including sources (16 and 17) produce the oppositely traveling circumferential beams.     Radially directed electric fields are applied to the beams of strength increasing with increasing distance from sources (16 and 17) for beam compression into spiral paths of a common reduced diameter passing through common space in zone (22) to promote collisions between ions in the oppositely traveling beams as they travel in the common space.

Title: Method and apparatus for dynamically selecting transmitters for communications between a primary station and remote stations of a data communications system
Inventor: FREEBURG THOMAS A
IPC: H04W68/00
Filed: 1983-10-20
Granted: 1987-03-24
Abstract: ABSTRACT A data communications sustem (Figure 1) is described that covers a geographic area divided into a plurality of non-overlapping zones (Figure 2) and includes a general communications controller (GCC, 104), a plurality of channel communications modules (CCM 106, 108, 110, 112) and associated transmitters (114, 120, 124) and receivers (116, 118, 122, 126, 128), and a plurality of portable radios (130, 132, 134). Message signals carrying alphanumeric information are communication between the GCC (104) and the portable radios (130, 132, 134) by way of a radio channel. Each CCM (106, 108, 110, 112) takes a signal strength measurement every time it receives a message signal from a portable radio (130, 132 or 134). The GCC (104) gathers the signal strength measurements from the CCM receivers (116, 118, 122, 126, 128) receiving the same message signal and computes an adjusted signal strength for each zone. The GCC (104) then selects the zone having the largest adjusted signal strength for determining the location of the portable radio (130, 132 or 134) that transmitted the message signal. Whenever the GCC (104) transmits a message signal to a portable radio, the CCM transmitter (114, 120, 124) is used that covers the zone having the largest adjusted signal strength for the last transmission from that portable radio (130, 132, 134). Since the GCC (104) can be simultaneously transmitting message signals to portable radios (130, 132, 134) in other zones using non-interfering CCM transmitters (114, 120, 124), information throughput is greatly enhanced.

Abstract: "PRIMARY BATTER SYSTEM"              Abstract of the Disclosure A battery system (10,110) wherein an electrolyte solution of lithium hydroxide dissolved in seawater is circulated through a battery cartridge (11,111).          The system is placed under pressure.  A portion of the electrolyte mixture is discharged from the system through a suitable pressure regulating valve (20) while concurrently, fresh seawater is delivered into the system as by a pressurizing pump (17).  The increased pressure acts to increase the density of the gaseous portion of the ejected gas liquid mixture, reduce the volume of the gaseous portion of the ejected gas-liquid mixture, thereby reducing the total volume of the ejected mixture, and reduce the ratio of gas volume to liquid volume in the system as well as the ejected gas-liquid mixture.

Abstract: ABSTRACT In a battery operated, remote transmitter for a consumer instrument, a microprocessor controls operation of the transmitter.  The collector current path of a PNP on-off transistor is coupled between the battery and a voltage supply terminal of the microprocessor.  To power up the microprocessor, a keyboard switch in the transmitter is depressed in order to ground the base of the on off transistor and turn on the transistor. An NPN transistor forms a latch with the PNP transistor to maintain the on-off transistor conductive.  After completion of the transmitter signaling, the microprocessor switches an output port to the ground state.  The output port is coupled to the base of the NPN transistor and bypasses current therefrom to initiate the regenerative deactivation of the latch.  With the latch deactivated, conduction of the on-off transistor is cut off.  The voltage supply terminal of the microprocessor is disconnected from the battery to power down the remote transmitter. The emitter of the NPN transistor is coupled to a tap on the battery to ensure reliable self-turn-off of the microprocessor.
