Patent ES-452115-A1 (ES)
Title: Apparatus and method for neutralizing static charges in sheet/web feeding devices
IPC: G03G21/06
Filed: 1976-10-05
Abstract: A corona and associated electrical drive as shown herein, neutralize the static charges on non-conductive sheets or webs. The neutralization of static charge is accomplished by passing the material to be neutralized under a double wire corona. Both wires in the corona are connected to an AC signal. The AC signal drives both wires with a signal that alternates in polarity at frequency f. The wires are spaced apart a predetermined distance calculated from a function dependent upon the frequency of the AC signal and the speed of the paper moving under the corona wires. The predetermined distance is such that a given area of the paper will pass under one wire at a first polarity and under the second wire at the opposite polarity. Further enhancement of neutralization can be accomplished by using a second double wire corona out of phase with the first double wire corona. In addition the sheet or web as it passes under the corona wires is supported to prevent static charge on the support from balancing a static charge on the sheet or web. Accordingly, the only static charge present as the sheet or web moves under the corona is that charge carried by the sheet or web. The corona wires will neutralize that charge either by discharging it with oppositely charged ions or depositing oppositely charged ions to balance the charge already on the sheet or web. Thus as the sheet or web moves away from the neutralizing station the sheet or web has a net charge which is substantially zero.
Patent ES-454062-A1 (ES)
Title: Pellet length and end squareness inspection apparatus
IPC: G01B5/25
Filed: 1976-12-07
Abstract: Apparatus for determining pellet length and end squareness which includes a base supporting a pair of linear variable differential transformers (LVDT) between which a pellet is placed for measuring end squareness. The LVDT's are perpendicularity detectors and each includes appropriate windings contained in a housing and an armature axially slidable therein. The armature is mounted on a shaft having extensions on opposite ends thereof. A swivel plate is attached to one end, while the other end is supported in a framework for the inspection apparatus, the arrangement being such that the housing containing the windings moves axially relative to the stationary armature. When a pellet is placed in position, each detector is advanced toward the pellet until its swivel plate contacts the pellet ends. If the pellet ends are not square, the swivel plates cock at an angle, thereby displacing the windings with respect to the armature. The relative displacement will be proportional to the tangent of the angle between the pellet ends and a plane perpendicular to the pellet axis. The pellet length is measured by a second LVDT which includes windings in a stationary housing. The armature moves relative to the windings and measures the relative distance between the swivel plates so that as the perpendicularity detectors sense the end squareness, the third LVDT senses pellet length along its axis. The output from the LVDTs is supplied to conventional readout circuitry and an indicating device which shows pellet length and end squareness.

Title: Modular tubular solar energy collector apparatus
IPC: F24S10/70
Filed: 1978-02-09
Abstract: The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold. The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configurations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes. The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space. Solar energy collected on the absorber surface of the inner glass tube wall is transmitted to the U-tube and liquid therein. The U-tube within the collectors is blackened and non-reflecting. Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer. The heat transfer liquid is entirely within a closed circuit, which avoids leaks, reduces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems.
