The relay optic 12, 18 comprises a relay lens 12 and an axis deviation arrangement 18, having a pair of surfaces A, B preferably formed of holograms which are mutually inclined at an acute angle each surface A, B being both transmissive and reflective according to the angle of incidence of light thereon.

Abstract: One or more antenna elements are submerged beneath a faired cover over a roof supporting member of a motor vehicle or hidden behind or as part of the front grill. Usually a conductive support extends behind the antenna elements and are electrically isolated therefrom to form the ground plane of the antenna. In some cases the antennas can be the structural members electrically isolated from the remainder of the body, but physically connected thereto. RF absorbers may be positioned spaced from radiating antenna elements to prevent antenna cross talk and exposure of occupants of the vehicle to high RF power densities. The antenna elements are especially useful in providing collision avoidance radar.

Abstract: A method and an apparatus for reducing the grain size of crystalline explosive provide for, first of all, dissolving the coarse crystalline explosive in an organic solvent. Subsequently, the dissolved explosive is brought together with ice water in a precipitation reactor. In the precipitation reactor the precipitation and crystallization of the explosive occur, while turbulent agitation takes place. A filtration stage is connected downstream of the precipitation reactor. A fine crystalline explosive is obtained, having a mean particle size of from 4 to 6 micrometers.

Abstract: A plasma arc torch includes a torch body defining a discharge axis, an electrode coaxially aligned on the discharge axis, a nozzle assembly positioned adjacent the discharge end of the electrode, and a heat shield removably secured on the torch body. A power supply delivers electrical current to the electrode to create an electrical arc, and a plasma gas is delivered so as to surround the arc. Also, a pressure sensing system is provided for sensing the pressure of the plasma gas and for disabling the power supply if there is insufficient gas pressure, such as when the heat shield is removed.

Abstract: A silicon carbide semiconductor device includes a silicon carbide substrate, an active layer in the substrate and a silicon carbide buried layer which provides a conduction barrier between the substrate and at least a portion of the active layer. The buried layer is preferably formed by implanting second conductivity type dopants into the substrate so that a P-N junction barrier is provided between the active layer and the substrate. The buried layer may also be formed by implanting electrically inactive ions into the substrate so that a relatively high resistance barrier is provided between the active layer and the substrate. The electrically inactive ions are preferably selected from the group consisting of argon, neon, carbon and silicon, although other ions which are electrically inactive in silicon carbide may be used.

Abstract: The use of certain herbicidal semicarbazones and salts thereof as potentiators or enhancers of herbicidal and/or plant growth regulating substances.

Abstract: Method of monitoring the quality of an advancing yarn by continuously measuring the yarn tension, which includes determining the progression of the yarn tension upon occurrence of a defined failure (failure record), storing the failure record in a data memory, comparing the measured yarn tension with the failure record and generating an alarm signal, when a range of the yarn tension progression shows a similarity to the failure record.

Abstract: An acceleration sensor includes an acceleration mass and a substrate mounted so that a cavity is defined therebetween and so that the acceleration mass moves relative to the substrate when an acceleration of the sensor changes. The sensor also includes a diamond field emitter for generating an electron beam through the cavity between the acceleration mass and the substrate. Accordingly, the distance between the acceleration mass and the substrate affects the current of the electron beam which is measured to determine the acceleration of the sensor. The sensor may alternately include an annular extraction electrode in a cavity between a substrate and a collector together with a diamond field emitter for generating an electron beam which passes through the annular extraction electrode. The annular extraction electrode is moveable relative to the substrate in response to changes in an acceleration acting on the sensor.

Means, such as opposed glue strips extending along the side portions, are provided for securing the film material to the rigid panel and for cooperating with the folding side portions to tighten the film against objects between the film and the center panel portion when the side portions are folded in a direction away from the film. The panel may include a fold line extending through the center panel portion for allowing the object to be inserted and secured beneath the film. The panel may also include openings into which projection on the folding side portions may be inserted to tighten the film. An associated method is also disclosed.

Abstract: A method of treating a subject under cardiac arrest comprises the steps of: blocking the descending aorta of the subject; then withdrawing blood from the subject; oxygenating the blood withdrawn from the subject; and perfusing the aortic arch of the subject with oxygenated blood in an amount effective to deliver oxygen to the heart of the subject. This method enables the subject to continue to receive oxygenating material (i.e., blood in this instance) without the danger of volume overload that would be present if another oxygenated solution were continuously infused.
