摘要： An anode for cathodically-protected steel-reinforced concrete is embedded in an ion-conductive overlay on the concrete structure. The anode comprises at least one sheet of highly expanded valve metal mesh having a pattern of voids defined by a network of valve metal strands connected at a multiplicity of nodes. This provides a redundancy of current-carrying paths through the mesh which ensures effective current distribution throughout the mesh even in the event of possible breakage of a number of individual strands. The surface of the valve metal mesh carries an electrochemically active coating. At least one current distribution member is welded to the valve metal mesh. The entire area of the structure to be protected, excluding non-protected openings for obstacles and the like, is covered by a single piece of the mesh, or several pieces in close proximity with one another.

摘要： Cathodic protection of a reinforced concrete structure utilizes a metal anode such as a zinc anode in combination with a pressure sensitive ionically conductive hydrogel in contact with at least a portion of the surface of the anode. Preferably, the anode and ionically conductive hydrogel are flexible and supplied in roll form. The combination may further include the addition of salt to the hydrogel as well as application to the metal-hydrogel combination of Type III cement. The cathodic protection may be carried out with or without a power source.

摘要： The application discloses a combine machine including an air baffle plate for adjusting air flow to a cleaning chamber used for removing waste material from grain. The cleaning chamber acts to deliver a predetermined supply of air to such grain material to remove chaff and trash material from the grain. In addition to a manual control, the air is controlled automatically by sensing the manifold pressure. The sensed air pressure is supplied to a cylinder which is connected to a link assembly and to a baffle plate which controls the air supply to the cleaning chamber. Under load the baffle plate is automatically moved toward an open position. When the load is decreased the baffle plate is moved toward a closed position to reduce the air supply delivered to the cleaning chamber.

摘要： Disclosed is a process for the formation of olefin-vinyl alcohol copolymer pellets which comprises mixing particles of the copolymer with water to obtain a wet cake containing about 20-70% solids by weight to thereby obtain a plasticized mass of the copolymer, thereafter extruding the copolymer at a temperature of about 5.degree.-7.degree. C. below the melting point of the mass through a nozzle to form a rod, and dividing the rod into individual pellets.

摘要： Disclosed is a method of monitoring planar sections of material having generally parallel crimps, the material having a longitudinal dimension extending generally perpendicular to the crimps and a transverse dimension generally parallel to the crimps. The material, such as a bundle of crimped fibers or tow, generally defines a plane, and the method comprises(a) illuminating the material along a line generally longitudinally of the material and over a plurality of the crimps by causing a plane of light, or the plane defined by sweeping a ray of light, to intersect with the surface of the material at an angle of between about 30.degree. and about 60.degree. with the plane of the tow when viewed along the tow band, such that the light intersecting the crimped material produces a generally zig-zagged line of illumination when viewed from an angle other than that of the light source, the peaks and valleys of which illustrate the profile of the crimped material, and(b) recording the pattern of the generally zig-zagged line from an angle relative to the material different from the plane of light such that the profile of the material can be determined.
