Abstract: A temperature control system (10) for a passenger van having individual temperature selection controls (60, 134) for passengers in the forward and rear sections of the passenger compartment.  Separate exothermic heat exchangers (28, 100) for circulation of engine coolant therethrough are provided for the forward and rear passengers.  Each heat exchanger is supplied by a coolant control valve (106, 26) and individual blowers (109, 42) provide a stream of forced air over the heat exchangers.  A thermistor (148, 58) senses the temperature of the air discharge over each heat exchanger and a controller sums the sensed temperature signal with a user selected relative temperature reference signal provided  independently by the forward and/or rear passenger selector inputs and a valve position signal; and, the controller generates a control signal proportional to the summation.  An electrical actuator for each valve (50, 124) moves the valve until the sum is a null for controlling coolant flow to each heat exchanger to thereby regulate the discharge air temperature about the individually selected relative levels for the front and rear independently of the selected blower speed.  Air conditioning evaporators (82, 152) may be disposed upstream of each of the heat exchangers; and, the thermistors sense the combined effect of heating and cooling and the system continues to modulate coolant flow to the heat exchangers for temperature regulation.

Abstract: SURVIVABLE SYSTEM Abstract To prevent an interruption of service due to a break in an optical fiber, diversely routed lightwave systems are utilized. For example, at the transmitting end, a fiber line is split into two, and each of the two lines traverse a physically diverse path. At the receiving end, the signal in one of the lines is selected and demodulated. If, for any reason, the signal is lost in the line being monitored, the receiver switches to the standby line. Diverse routing can be achieved by using two completely separate optical systems to send the same signal along diverse routes simultaneously; or, by splitting the optical fiber by means of a fused-fiber (3dB) splitter to send the same signal along two diverse routes. A 2x2 electro-mechanical optical switch can be used to select the appropriate optical fiber. A 3dB splitter is more economical than two separate optical systems. However, the 3dB splitter introduces a loss factor which is excessive. An optical modulator can be substituted for a beam splitter. The modulator, often comprising a lithium niobate switch, is used to impress a digital signal on a dc optical beam. The lithium niobate modulator has a cw optical input, an electrical control input representative of digital data, and normally two digital optical outputs. One output is generally used as the modulated line signal, and the other output, which is the complement of the modulated signal, is terminated in an index matching oil to prevent reflection. Briefly, in this invention, the previously discarded digital optical output of the optical modulator is not discarded. It is used as a signal source for the diverse route thereby avoiding the need for any further loss producing beam splitters. The advantages are significant. The laser is on continuously. Therefore, there is no chip. The power (on average) is directed 50% of the time to one output and 50% of the time to the other output. Thus, there is no power loss as in the case when a splitter is used. Where appropriate, at the receiving end, complementation can be performed to retrieve the original bit pattern if the complement of the signal is being detected. (FIG. 7).

Abstract: ABSTRACT OF THE DISCLOSURE           A control for an electrical charging system for selectively connecting two alternators producing charging current at each of six outputs to the output of a first battery and the output of a second battery serially connected to the first battery output.  The control comprises a plurality of switchable full wave bridge rectifiers for connecting each of the alternator outputs to one of the first battery output and the second battery output so that the one battery is charged by the alternators.  The switchable rectifiers are alternatively switchably connectable to the other battery output so that the other battery is charged by the alternators.  The control also includes a switching circuit for switching first one, and then the next of each of the switchable circuits as the voltage across the other battery is increasingly less than the voltage across the one battery so that the rate of charging of the other battery is determined by the amount the voltage across the other battery is less than the voltage across the one battery.

Title: Method for reducing sox emissions during the combustion of sulfur-containing combustible compositions
Inventor: HAYES MICHAEL E
IPC: C09K23/00
Filed: 1989-09-25
Granted: 1993-10-12
Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to the reduction of oxidized sulfur compound SOX emissions produced during combustion of sulfur (S)-containing combustible compounds.  More particularly, this invention provides a method for reducing such emissions wherein the combustible compound is mixed with an admixture of a water soluble and a water insoluble sulfur sorbent.  Use of such admixtures, remarkably, produces a reduction in the SOX level far greater than would be expected based on the activity of each sorbent alone.  Extremely viscous hydrocarbons can be burned as preatomized fuels, which can also be mixed with sorbent admixtures.  Clean burning fuels comprising sulfur-containing combustible compounds and sorbent admixtures are also provided.

Abstract: A flushing means for drilling tools comprises a guide member (10) carrying a drill bit (20) and being rotatably centered by the mouth of a casing tube (11) which is adapted to follow the drilling tool downhole during drilling. The drill bit (20) has a bit portion (22) that projects laterally beyond and is spaced axially in front of the casing tube (11) so as to drill a hole larger than the casing tube (11). There are external flushing grooves (70,71) on the guide member (10) adapted to lead the outflow of flushing medium and debris from the hole during drilling into the casing tube (11). At least one of these grooves (70) extends from front to rear of the guide member (10). One or more further grooves (71) are open towards said rear while ending blindly into the periphery of the guide member (10) spaced from its front. By retraction of the guide member (10) its front enters the casing tube (11). That closes the blind grooves (71) and an intensified flushing is thus possible via the remaining open grooves (70) that extends from front to rear of the guide member (10). The cutting front (40) of the bit portion (22) is flushed rotatively in counter flow to the rotational drilling direction (8) towards the full length groove (70).

Abstract: In a multi-processor system of the type in which each processor is provided with its own unique bus which has an addressing system organised in such a manner that all store locations and peripheral equipments are addressed as part of a comprehensive single addressing system. Each address comprises a module number and an offset address. Each module in the system includes a module number comparator which detects the presence of its module address on a CPU bus and allows the offset address to be active within that module. The invention provides for the incorporation of similar mechanisms within a CPU allowing the CPU to address its own internal registers in an identical manner to its normal bus addressing mode. In addition the offset address includes a "bit portion address" which selects a mask which is used when performing the required internal register operation. The main advantage of such an arrangement is the simplification of the instruction range for the CPU as "normal" instructions may be used to manipulate the internal registers rather than having special purpose instructions dedicated to the manipulating of the registers.
