Title: Heating furnace control
Inventor: KLAMMER HELMUTH
IPC: F27D19/00
Filed: 1984-09-07
Abstract: The invention relates to a continuous heating furnace control. In order to achieve even heating of material 3 as it passes through the furnace, taking account of irregularities in passage, in material dimensions, and in the hearth lining the furnace is controlled according to the invention by taking over the length of the furnace one or more items of furnace firing data, e.g. temperature as at 10 or fuel and air consumption, progressively converting the measurements taken into signals representative of the temperature change of the pieces of material and the temperature of each piece of heat material located on the length of the furnace as actual temperature. The actual temperature profile so produced is compared with various desired temperatures predetermined locally over the length of the furnace (a reference temperature profile) and in the zones in which a deviation is found, the furnace firing 5, 6 is adjusted to minimize variations therefrom. <IMAGE>

Title: Computers
Inventor: WILLIAMS RICHARD ARTHUR LEONAR
IPC: G06F9/32
Filed: 1984-10-09
Abstract: Conventional computers are based on the architecture devised by Von Neumann et al. The main stumbling block in computer design at the moment appears to be program control; it is not easy to match this to the requirements of a rule-based expert system. The invention proposes a method of controlling a computer in which all program control is performed by a "pseudo-associative" process, a fast table lookup technique being implemented (preferably in hardware) (2) to select the correct rule, whereupon the application of the rule modifies the conditions and the pseudo-associative process is used to find a new rule . . . and so on. The procedure to be performed at any given time is selected, from a limited number of possible procedures, upon the basis solely of the result of the previous procedure, this result being available (26) as a number value (the computer's "state" after affecting the previous procedure) that is hashed (24) according to some predetermined algorithm to identify the correct following procedure. <IMAGE>

Title: Probabilistic scrambler and method of probabilistic scrambling
Inventor: CORRIGAN JOHN
IPC: H04L7/00
Filed: 1984-06-29
Abstract: Probabilistic scrambling, and the complementary probabilistic descrambling, for purposes of assuring reasonably frequent transitions in a transmitted signal for the purposes of receiver clocking. The transmitter (30) is provided with apparatus (16) for generating one or more different seeds. For transmitting any particular message, a seed is selected. The seed is generated randomly in order to increase the probability of successful transmission. The seed is used to generate a scrambling bit sequence which is combined with the data for transmission to generate a transmitted signal. The transmitted signal include at least some information identifying the scrambling bit sequence or the particular seed used for generating the scrambling bit sequence. Preferably, the seed itself (in scrambled or unscrambled form) precedes the scrambled data. At the receiver, (40) this seed is used to generate a complementary descrambling bit sequence which is combined with the received data to generate the original data scrambled at the transmitter (30).

Title: Ultrasonic range finding
Inventor: MCKNIGHT JAMES ALAN
IPC: G01S15/36
Filed: 1985-04-12
Abstract: Range finding equipment is employed in a nuclear reactor to monitor the spacing between structural components (22,24) of the reactor which are under stress. A manipulator (32) carries a pair of send-receive ultrasonic transducers (30) arranged back to back so as to direct ultrasound signals towards reflectors (26,28) associated with the structural components to be monitored. The transducers are pulsed with signals derived by gating a few cycles of a sustained reference signal of sine wave form. The resulting echo signals provide transit time information and are compared with the reference to provide phase displacement information from which the spacing between the reflectors (26,28) can be derived with a high degree of precision. The equipment may be calibrated in the same environment by positioning the transducer assembly between a pair of unstressed reflectors of known separation. <IMAGE>

Patent GB-2172721-A (GB)
Title: Protective software
Inventor: ROBERTSON JOHN ANGUS
IPC: G06F12/14
Filed: 1986-01-24
Abstract: Data processor address bus (12) provides an input to an address memory (22) which retrieves an output address word for presentation via a translated address bus (18) as the address to a system memory. Control (20) determines the state of a flipflop (26) whose output is coupled to the most significant bit-line (24) of the input to the address memory (22). The address memory (22) is partitioned into an upper half where each input word received on the processor address bus (12) retrieves an unmodified version of itself and a lower half wherein each input word retrieves a unique modified version of itself where the order of the binary digits as shuffled according to a predetermined scheme. The flipflop (26) may be switched via interrupt or other control lines from a data processing unit or via a monitor monitoring the processor address bus (12) for one or more predetermined address words. The data processing unit thus controls whether a modified or unmodified address will be provided to the system memory. Alternatively, the unmodified address may be provided via a multiplexer instead of from the address memory (22) (Fig. 3). Address translation units may be cascaded (Fig. 4). <IMAGE>

Abstract: 884,532. Valves. ROBERTSHAW-FULTON CONTROLS CO. March 10, 1959 [June 13, 1958], No. 8265/59. Class 135. A fluid control device e.g. for a gas-fired space heater comprises a thermal means 36, 41, a first operative connection 130 between the thermal means and a valve mechanism for abruptly moving the valve mechanism between a closed position and a medium flow position in response to a first movement of the thermal means, and from a minimum to the closed position in response to a fourth movement, and a second operative connection for gradually moving the valve mechanism between the medium flow and a maximum flow position in response to a second movement of the thermal means, and from the maximum to the minimum position in response to a third movement, the minimum flow position being below the medium position. On contraction of bellows 37, cup 46 moves down under spring 52 and pendant legs 62 on the cup flex a plate 146 in contact with the snap action device 130. At a certain point dependent on the adjustment of the knob 161 and screw 48 connecting the cup to the bellows the snap-action device moves over centre and through stem 122, 116 opens valve 114 and through strong spring 111 and cage 106 opens valve 96 against weak spring 104, the total valve opening being the medium position in which the cage abuts a lever 84. Further contraction of bellows 37 again flexes plate 146 and two further legs on the cup 46 pivot lever 58 and through adjustment 66 and rod 80 also pivots lever 84 against spring 89 to relieve spring 104 and allow the valves to open gradually to their maximum position. On expansion of the bellows, levers 58, 84 gradually close valve 96 controlling the main flow from inlet 12 to outlet 14 and allow the minimum flow via cage opening 108, valve 114, around the square stem 116 through the hollow stem of valve 96 to chamber 126 and vents via passages and a throttle to the outlet. Further expansion of the bellows then allows the valve 114 to snap closed. A manual valve is provided connecting chambers 79 to chamber 126 leading via the throttle to the outlet.

Title: Active shaft-grounding system for ELF signature control
Inventor: BEDARD JOSEPH ROBERT JACQUES
IPC: B63G9/00
Filed: 1989-12-08
Abstract: In a ship or submarine grounding system for substantially eliminating the shaft-rate related alternating-field electromagnetic signature of the vessel, caused by the shaft-rate related modulation of the corrosion current, by maintaining the shaft at a fixed potential relative to the vessel's hull, the shaft-to-hull voltage is sensed at 19 and compared to a predetermined level and a current driver 28 provides a current at 20 from the propeller shaft to reduce the continuous voltage between the shaft and hull, the output current is biased so as to also reduce the bearing modulated shaft current, between the shaft and the hull, which is caused by the residual voltage between the shaft and the hull. A feedback loop biases the current driver so as to substantially eliminate the effects of semiconductor bias voltage on the shaft potential, thus maintaining the shaft at the desired potential over the operating range of the output current, and thus substantially eliminating the modulation of the shaft current and substantially eliminating the resulting electromagnetic signature.
