Abstract: PLEATED METALLIZED FILM CAPACITOR                 WITH STAGGERED EDGES     Abstract of the Disclosure An electrical capacitor is formed utilizing a thin dielectric layer which is metallized on both sides to provide electrode areas. The capacitor is formed by pleating, or folding, the dielectric layer along its longitudinal dimension an odd number of times. The pleats are not creased but are allowed to form smoothly curved edges in which the radius of such bend is at least equal to the thickness of the film. In addition the edges of the pleats are progressively staggered so that the centers of the bend of one pleat edge is removed a distance of at least four film thicknesses from its neighboring centers. This configuration prevents the end of the capacitor from forming a "bar-bell" shape and in addition minimizes mechanical damage to the film and alternation of the electric field.

Abstract: ABSTRACT OF THE DISCLOSURE           A splint formed of a corrugated plastic material has a first elongated panel having a pair of laterally-spaced longitudinal fold lines that divide it into an inner base and first and second outer sidewalls.  A second elongated panel is disposed rearwardly of the first panel and has a pair of laterally-spaced longitudinal fold lines that divide it into an inner base extension and first and second outer sidewall extensions.  The first sidewall and the first sidewall extension are pivotable as a unit to a substantially upright position with respect to the base and the base extension, respectively, and the second sidewall and the second sidewall extension are also pivotable as a unit to a substantially upright position with respect to the base and the base extension, respectively.  The first sidewall and the first sidewall extension are joined by a first removable portion and the second sidewall and second sidewall extension are joined by a second removable portion.  Each removable portion extends from the inner edge of the sidewall outwardly to the outer edges of the sidewall and the sidewall extension and is bounded by a first pair of tear lines each of length greater than the lateral distance between the inner edge of the sidewall and the outer edge of the sidewall.  Each tear line is defined by a series of spaced cuts in the corrugated plastic material.  Upon removal of the removable portions, the rear panel is pivotable to a substantially upright position with respect to the inner base of the first panel, and the rear panel and the first panel have co-operating locking structure to lock the rear panel in the upright position.  A similar splint with one end open and the other end foldable into a box is used to form a femoral splint having a windlass and a traction cord extending through the box end.  A single panel with folding sides may be used to form a stretcher.

Abstract: DC EXCITATION OF HIGH PRESSURE GAS LASERS             ABSTRACT OF THE DISCLOSURE         A gas laser system with moderate speed gas flow through the optical cavity to facilitate D.C. excitation of the gas to lasing levels.  An electrode assembly is positioned so as to provide a glow discharge transverse to the optical axis within the optical cavity when a high D.C. voltage is applied thereto.  By maintaining the moderate rate of flow of gas through the cavity, the glow discharge is stabilized while the gas medium is maintained at high pressure.  Proper choice of electrode geometry and flow rate of the gas through the optical cavity allows the laser system to operate at pressures from a few Torr to atmos-pheric pressure and above thereby producing a high power CW output.

Abstract of the Disclosure There is disclosed process and apparatus for treating a comminuted solid carbonizable material, such as comminuted municipal waste; sawdust, granulated coal, shredded tires and the like wherein the material is caused to be pyrolyzed in a horizontally disposed elongated reaction zone essent-ially free of any oxygen containing gases at ambient pressure and at a temperature of from 400°C, to 900°C., The material is passed through the reaction zone by paddle-like impellers mounted on a shaft while being subject to an indirect heat transfer relationship to a burning air fuel mixture spirally swirling within a heating zone about the reaction zone and withdrawn from a lower portion of the heating zone. During pyrolysis, the material is chemically changed into valuable gaseous, liquid and solid products.     i

Granted: 1981-04-07
Abstract: ABSTRACT                 Magnesium metal is produced in a two-stage chemicothermal process employing metallothermic reduction of MgO using Al metal, present in an Al alloy, as the reducing metal in one stage according to the reaction 2A1 + 3MgO ? 3Mg + Al2O3 and employing a carbothermic reduction, Al2O3 + 3C ? 2Al + 3CO   in the other stage to regenerate the Al metal for recycling back to the metallothermic reduction step.  The process substantially avoids the reversion reaction, Mg + CO + MgO + C, by separating the formation of Mg from that of CO (carbon monoxide) and does not rely on having to remove slag from the reactors. 18,480-F
