Abstract: Reinforced concrete typically having steel reinforcing bars embedded in the concrete can have valve metal anodes forming a part of a cathodic protection system for the concrete structure. For embedding the anodes to serve in the cathodic protection system there is now used a fiber-filled concrete overlay. Polymeric or ceramic fiber is particularly useful in such overlay. There is now provided not only reduced shrinkage cracking for the overlay itself, but also lower current demand for the cathodic protection system.

Abstract: An adjustable guide arrangement for aligning a substrate such as a shoe upper to be treated with a reinforcing substance, onto a biased plate of a rotatable cube for subsequent pressing against a carrier belt of a reinforcing machine. The guide arrangement comprises a housing adjustably supported on a frame portion of the machine, the housing holding a piston and cylinder unit having a piston rod therefrom which secures a guide bracket. The bracket has several slots therein which each adjustably support a guide pin. The guide pins are registerable with the biased plate, and act as an adjustable backstop for the substrate as they are being loaded onto the rotatable cube. The piston rod is retractable into the cylinder, to pull the guide pins out of the way of the cube as it is caused to rotate.

Abstract: The present invention relates to a process for scavenging hydrogen sulfide which frequently becomes entrained in drilling fluid during the course of drilling operations through subterranean formations. The process consists of introducing a solid oxidant in powdered form into the circulating drilling fluid when hydrogen sulfide is encountered. The solid oxidants are selected from the group consisting of calcium hypochlorite (Ca(OCl).sub.2), sodium perborate (NaBO.sub.3), potassium permanganate (KMnO.sub.4), and potassium peroxydisulfate (K.sub.2 S.sub.2 O.sub.8). The solid oxidants are soluble in the drilling fluid, promoting fast and complete scavenging reactions without adversely altering the drilling fluid rheology.

Abstract: A small, very low cost, wide margin core memory couples a return current drive scheme with a crossover-free sense winding extending parallel to the Y drive conductors to eliminate the assembly time and wasted substrate space associated with sense winding crossovers. The return currents generate small noise signals which cancel with partial select noise signals to provide noise signals comparable to a 3 wire, 3D bow tie sense winding.

Abstract: A highly efficient core memory drive system passes currents down a selected X and Y conductor and divides the currents for return through the unselected drive wires in the same X or Y dimension. The drive conductors are coupled to drive and sink switches at a drive end and the X conductors are connected together at an opposite common end and the Y conductors are connected together at an opposite common end. Resistors provide a current path between the drive end of each X conductor and an X resistor bus and between the drive end of each Y conductor and a Y resistor bus. A pair of switching transistors including a sink transistor and a drive transistor is connected to a drive end of each conductor to generate a drive current therein. The drive current divides equally among the unselected conductors at the common end to return through the unselected conductors and through the resistors to the resistor bus.

Abstract: A conditioning apparatus for a rotating annular belt at a powder reinforcing machine, wherein an arrangement of arms are pivotably secured to a frame portion of the machine, to scrape the belt as it intermittently rotates, to deposit a release fluid onto the width of the belt as it rotates, and to spread the fluid evenly across the belt if fluid puddles up thereon due to the intermittent nature of the belts rotation. The arm for releasing fluid onto the belt has a felt portion which receives fluid from a conduit in communication with a reservoir for the fluid. All the arms are pivotably attached to the frame portion of the machine, adjacent the annular belt, and all are lockable in an upright position to facilitate repair or replacement of any components thereof.

Abstract: The method of aligning and loading a substrate onto a powder reinforcement machine wherein a guide pin arrangement is adjusted with respect to settings on a portion of the machine frame and then adjusted distancewise from the machine frame, the guide pins themselves then adjusted with respect to the guide pin support, to facilitate alignment of substrates on the machine, the settings being repeatable for differently contoured substrates if desirable. The guide pin support being shiftable for removal from the path of a substrate transport cube, permitting rapid alignment of successive substrates of a particular configuration.

Abstract: In a highly flexible but economical mapping system and method, a different multidigit source code is assigned to each element in a first set of elements containing a subset of elements to be mapped. The digits of an assigned source code are grouped into at least two different groups. For each element to be mapped, a multidigit destination code is stored identifying each mapped element within a second set of elements to which it is to be mapped. Each digit of the destination code is stored in association with a state that is definable by a group of digits of the source code. Upon receipt of a source code, if it is detected as representing an element to be mapped, the stored destination code associated therewith is retrieved and substituted for the source code to effect the mapping.

Abstract: A magnetic core stack is comprised of a laminate of individual layers of substantial thinness mounted on a common stiff base member to provide a rugged, low mass structure of high resonant frequency. Each of the individual layers is comprised of a plurality of magnetic cores held in place by soft, energy absorbing material such as silicone rubber coated on the surfaces of opposite ground plane forming materials such as very thin sheets of aluminum. The laminate is formed from a single layer of material which supports a layer of magnetic cores and which is folded over upon itself one or more times to form the separate layers of the laminate. In one embodiment, a sheet of aluminum coated with silicone rubber on both sides is inserted as the single layer of material is initially folded over to form a two layer stack in which each layer of cores is held between opposite sheets of aluminum by silicone rubber coated on the aluminum.

Abstract: A core memory utilizes an auxiliary core that is driven concurrently with selected data cores to increase tolerances by automatically tracking the peaking time and the output magnitude. Wide variations in both the magnitude and duration of core output switching signals are compensated by use of the auxiliary core to control the sensing strobe time during a read part cycle and drive current duration during both read and write part cycles. Subtracting half of the auxiliary core output switching signal from a selected data core output switching signal normalizes the difference about zero volts with a one being indicated by the presence of a positive voltage and a zero by a negative voltage. With the reference threshold at zero there is no precise adjustment. Since the peak of the auxiliary core output tracks the peak of the selected data core output, substantial changes in the peaking and switching times do not interfere with accurate determinations of data core data states.

Abstract: A program for determining the data for translation and key PROMs in a mapping system maps an A group of input states into an AK X AT A map and a B group of input states into a BK X BT B map. The smaller B group is mapped first with even packing in which the number of mapped elements assigned each BT state is maintained approximately equal as mapped elements are assigned BT locations. The larger A group is mapped last with close packing in which mapped elements are assigned preferentially to the AT state with the most previously mapped elements. The A group and B group are each ordered according to the number of mapped elements associated therewith from most to least and mapped in sequential order if possible.

Abstract: A low cost, low power inhibit current drive circuit includes a pair of sense-inhibit conductors each inductively coupling 16K low drive memory cores and having sufficiently low resistance to permit steady state inhibit current magnitudes to be energized by a 5 volt source which is diode coupled thereto, a switch coupled to selectively pass inhibit current in response to a command signal, a storage capacitor coupled to the transistor collector, and a series combination of an inductor and a resistor coupled to charge the capacitor to a voltage greater than 5 volts and thus provide a rapid rise of inhibit current to the steady state level upon closure of the switch. Use of the charged capacitor to provide high voltage energy at switch closure reduces the required maximum current from the high voltage source while the inductor reduces capacitor charging time for a given size of series resistor to further reduce the maximum current requirement from the high voltage source.

Abstract: A large, 2 wire, 2-1/2D core memory includes four, 1K (1024) by 1280, core frames with 1280 Y conductors each stringing and inductively coupling a column of 1024 cores in each of the four frames and 4K orthogonal X conductors each stringing and inductively coupling one row of 1280 cores. A word position within the memory is defined by 5 pairs of Y conductors, a corresponding X conductor from each frame, and selection of relative current directions in the Y conductors. Reading of a 20 bit word is accomplished with 5 sense amplifiers in four rapid succession read sub-operations. Digit sense conductor noise recovery time is minimized by arranging for balanced, predictable delta noise on each digit sense conductor of a pair and by providing a multiple digit sense conductor pair crossover arrangement which results in a balancing of image current coupling into adjacent digit sense conductor pairs.

A bidirectional X drive and switching arrangement utilizes overlapping X drive currents and shared circuitry to maximize memory speed and reduce electronic components costs.
