Abstract: Infrared light barriers or video control systems are used, as is known, in monitoring bounded, plane areas, for example a level crossing. However, both solutions have the disadvantage that they are unreliable or are of a very complicated design. The invention provides a video control system which permits reliable evaluation using simple means. For this purpose, a camera is used to take and store two fields in each case, one being taken without flash, and the other with. A differential image, now containing only signal components caused by the light of the flash is obtained from the two fields. Given the presence of a three-dimensional object in the monitored area, there is produced on the side of the object averted from the flash a shadow signal which is evaluated and, if necessary, fed to the alarm-triggering device. <IMAGE>

Abstract: An acoustically operated burner control system [1] for optimally controlling a flow of air and fuel into a flame producing combustion burner [3] throughout a range of firing rates is disclosed. The system includes separate valve assemblies for modulating the flow of air and fuel into a burner, [3] a microphone [103] for generating an electrical signal indicative of the intensity of all sounds generated by the combustion flame having a frequency in excess of about 10 kHz, and a controller [43] including a programmable microprocessor electrically connected to both the air and fuel valve assemblies [45,58] and the microphone [103]. The system further includes a wave guide [105] for remotely acoustically coupling the microphone [103] to the combustion flame [15] in order to isolate the microphone from both heat and corrosive combustion products. Prior to the operation of the system, empirically-derived sound intensities associated with optimum stoichiometric combustion and minimum pollution are entered into the memory of the microprocessor. During operation, the microprocessor equates the sound intensity sensed by the microphone with the optimum sound intensity in its memory by regulating the position of the air and fuel valve assemblies [45,58].

Abstract: The present invention is a process for the carbothermic reduction of silicon dioxide to form elemental silicon. Carbon balance of the process is assessed by measuring the amount of carbon monoxide evolved in offgas exiting the furnace. A ratio of the amount of carbon monoxide evolved and the amount of silicon dioxide added to the furnace is determined. Based on this ratio, the carbon balance of the furnace can be determined and carbon feed can be adjusted to maintain the furnace in carbon balance.

Abstract: A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times. A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle. A hierarchical cache arrangement has an improved method of cache set selection, increasing the likelihood of a cache hit. A writeback cache is used (instead of writethrough) and writeback is allowed to proceed even though other accesses are suppressed due to queues being full. A branch prediction method employs a branch history table which records the taken vs. not-taken history of branch opcodes recently used, and uses an empirical algorithm to predict which way the next occurrence of this branch will go, based upon the history table. A floating point processor function is integrated on-chip, with enhanced speed due to a bypass technique; a trial mini-rounding is done on low-order bits of the result, and if correct, the last stage of the floating point processor can be bypassed, saving one cycle of latency. For CAL type instructions, a method for determining which registers need to be saved is executed in a minimum number of cycles, examining groups of register mask bits at one time. Internal processor registers are accessed with short (byte width) addresses instead of full physical addresses as used for memory and I/O references, but off-chip processor registers are memory-mapped and accessed by the same busses using the same controls as the memory and I/O. If a non-recoverable error detected by ECC circuits in the cache, an error transition mode is entered wherein the cache operates under limited access rules, allowing a maximum of access by the system for data blocks owned by the cache, but yet minimizing changes to the cache data so that diagnostics may be run. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement. The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.

Abstract: A superconducting motor (1) comprises a stator (3) and a rotor (5), both of which employ superconductive windings. The rotor includes two sets of windings, a large rotor winding (13) and a small rotor winding (15). The windings are connected to form a current loop (16) which is exposed to a magnetic field. Switches (S1, S2) or diodes (D1, D2) are employed to trap a maximum number of magnetic flux lines in the loop when the magnetic field is impressed on the loop. Thereafter, the trapped flux is transferred from the small to the large winding to run the motor. When the switches are closed, the loop acts as a perfect conductor whereby no flux change occurs within the loop.
