Abstract: An intermediate code memory for taking instructions from main memory and supplying them inline to a processing element is disclosed. Inputting instructions into the intermediate code memory from main memory is done using a DMA channel and may be done simultaneously with outputting instructions to the processing element. Outputting can be done from any location that is outside a dynamic window, whose position and size depend on the area in the code memory to which the code is currently being input. In addition, the code memory contains a LIFO stack and executes all subprogram call and return instructions so that the instructions presented to the processing element are inline. Normally, the instructions are output sequentially from the code memory, however, subprogram calls and returns, certain unconditional branch instructions executed by the intermediate code memory, and addresses passed from the processing element may change the instruction sequence.

Abstract: A flowmeter has an elongated probe with a rotor positioned at the distal end of the probe for insertion into a fluid flow and an elongated conductor in the probe that terminates adjacent the rotor. A signal generator induces a standing wave on the conductor, and rotation of the rotor, which acts as a capacitor, induces a reciprocating phase shift in the standing wave. The rate of reciprocation of the phase shift, as well as the change in amplitude at a point on the conductor, is proportional to, and indicative of, the flow rate of the fluid and is detected and measured as an instrumentation signal. The probe, rotor, circuit insulation, and seal components are all fabricated of materials that withstand extreme temperatures.

Abstract: A rotatable driver cup rotatably mounted in the top plate of a valve box cover or manhole cover with the open top of the cup opening above the top plate and the rest of the cup extending downwardly through a hole in the top plate to a position thereunder, a cup-shaped crank positioned concentrically around the portion of the driver cup that extends below the top plate, but the crank is too large to be pulled up through the hole. The driver cup and the crank are connected together so that they are axially immovable in relation to each other, but such that the driver cup can normally rotate freely in the crank. There are radially aligned apertures in both the driver and the crank, and a lock mechanism, such as a key and tumbler pin type cylinder lock, is positioned in the cup-shaped driver with a lock-actuated, radially extendable and retractable, tongue that can protrude through both apertures in the driver and the crank to engage the driver and crank together.

Said translation camera can be moved to any desired position over the reseau assembly, as well as toward and away from the reseau assembly, forming three coordinate systems, which are correlated together for precise mensuration of an object image digitized by the solid state camera.

Abstract: A protected, but unsealed rotor bearing for flowmeter turbine rotors and the like has an annular shoulder protruding axially from the rotor in concentric relation to the rotor axis in a manner that defines a cavity protruding axially into the rotor. An elongated bearing body with a cylindrical peripheral surface is mounted in a supporting frame and protrudes axially into the cavity. An axle on which the rotor is mounted protrudes into a bore in the bearing body such that the bearing interface is between the surface of the axle and the surface of the bore in the bearing body. A ball in the bore between the bearing body and the axle bears axial thrust. The peripheral surface of the bearing body does not contact the annular shoulder, but a face on the annular sholder that extends radially outward from adjacent the peripheral surface of the bearing body acts as a centrifugal flinger to dynamically divert contaminant particles away from the bearing surfaces.

Abstract: Method and apparatus for prefetching and buffering instructions between a code store and a processing element's decode logic. The apparatus is a code buffer that consists of a code RAM and its supporting logic that implements rules for bringing instructions into the code RAM from the code store and outputting them to the decode logic. These rules determine when writing to the code RAM is blocked and reading from the code RAM is blocked by using the write and read addresses and loop information stored in the supporting logic. The rules guarantee that the instructions to be executed are not overwritten, instructions being executed have, in fact, been brought into the code RAM, and loops are kept in the code RAM until they have been exited. The code buffer handles two types of branch instructions, inside branches to instructions that are within the code RAM and outside branches to instructions in the code store.

Abstract: A gas lock breaker for oil well pumps includes a stationary barrel with a standing valve on the bottom, a reciprocating piston in the barrel with a traveling valve on the bottom of the piston, an unseating rod positioned above the standing valve and adapted to protrude into the traveling valve to unseat the ball closure thereof near the bottom extremity of the downstroke of the piston. For a conventional well of any normal depth equipped with a pump jack for piston displacement anywhere in the range of 1 to 5 meters (3.3 to 16.4 feet), the unseating rod protrudes through the traveling valve a distance of about 1 to 15 percent of the piston stroke, or about 5 to 13 cm. (2 to 5 in.). The standing valve cage is preferably 12 to 20 cm. (4.75 to 8.0 in.), and the traveling valve is set to approach within 15 to 30 cm. (6 to 12 in.) of the standing valve.

Abstract: Apparatus and methods are disclosed for providing fast decoding of Reed-Solomon and related codes. Cases of one and two data symbol errors are decoded directly from the remainder using a large pre-computed table without calculating syndromes. Techniques for decoding cases of more than two errors are given where an optimized Chien search is used when more than four errors remain; when four or fewer errors remain, the Chien search is eliminated in favor of locating an error by direct solution of the error locator polynomial. The error locator and syndrome polynomials are adjusted after each error is found, and the error evaluator polynomial need not be computed.

Abstract: A method of treating sewage is disclosed that is particularly suitable for one or a small group of residential dwellings in environmentally sensitive areas. The raw sewage is flowed first into an aerobic first cell where it is aerated and forced into a highly aerobic condition where aerobic bacteria grow and consume phosphorus in a vigorous life cycle and then die. Substantial primary unloading of B.O.D., T.S.S., coliform, and phosphorous is accomplished in this first cell. The fluid from the first cell overflows into a second cell where additional sedimentary clarification occurs and it goes anaerobic. A third cell has an upwelling flow through a porous medium substrate where anaerobic bacteria converts nitrogen in nitrates and nitrites to nitrogen gas, and the fluid then flows into a fourth holding cell. The effluent in the holding cell can then be flowed intermittently through a sand filter that has a bed of dolemite for final removal of residual phosphorus before it flows into a drain field.

Abstract: The method of this invention includes the steps of positioning a reseau with grid marks on the object and sequentially illuminating the grid marks separate from the object and illuminating the object separate from the grid marks or in a manner that the grid marks are not visible with the object. The image of the grid mark positions, when illuminated, are digitized and stored in computer memory and correlated with the image of the object when it is illuminated and digitized. The scale of the image can also be correlated to the scale of the grid marks.

Abstract: The invention relates to a method and an apparatus for determining the cut (percentage) of one component of a multiphase fluid flowing in a pipeline, for example, oil or other hydrocarbon in a fluid flow that comprises oil, water, gas, and soil components, by use of NMR analysis. The fluid is flowed through an apparatus specifically designed to perform the analysis on the flowing fluid. Carefully sequenced 90.degree. pulse series are used to take advantage of the different spin relaxation times of the selected atomic species when they are constituent parts of molecules having inherently different levels of random molecular motion. The timing between pulses in a series and between series of pulses is chosen so that NMR emissions from unwanted matter do not occur, and FID peaks from the desired matter are registered.

Abstract: Disclosed is a serial encoder and time domain syndrome generator circuit utilized in a Reed-Solomon code application where the code has been defined with the conventional or standard representation of a finite field. The encoder will process k bits of an m-bit symbol per clock cycle, where 1.ltoreq.k.ltoreq.m and k evenly divides m. The encoder will process data in an interleave mode wherein data symbols of multiple codewords are interleaved in an interleaved data block. The encoder allows pipeline processing of register data within the encoder and time domain syndrome generator circuit to minimize circuit delay, and a linear network within the encoder is reduced in complexity by selecting a self-reciprocal code generator polynomial.
