The pan, free of sharp corners, is spaced apart from the interior bottom wall of the oven's cavity, and has height, width, and length dimensions such that when one dimension, in inches is N.lambda./4, where N is an odd integer from 1 to 15, then one of the other dimensions is N.lambda./4, wherein N.lambda./ is an even integer from 2 to 12, and the remaining dimension is N.lambda./4 wherein N is either an odd integer from 1 to 15 or an even integer from 2 to 12, being the wavelength of waves eminating from the klystron of the microwave oven.

Abstract: A method and apparatus for generating a high plume or "rooster tail" of water behind a water jet propelled marine craft, such as a jet ski, is characterized by the insertion of a water diverting member into the upper regions of the jet of water discharging from the jet propulsion system and diverting a portion of the water from the jet upwardly and outwardly away from the jet to form a tall plume of water above and behind the jet. In its preferred embodiment, the apparatus comprises a lever pivotally mounted on the upper side of the discharge nozzle of the propulsion system and selectively movable at its upstream end through a slot in the nozzle into the interior of the nozzle to divert a portion of the water from the jet stream upwardly and rearwardly away from the nozzle.

Abstract: A pellicular laminate comprising: a web of polypropylene film, on at least one surface of which is a layer of polyurethane; a metal, preferably a ductile metal such as gold, which has been deposited on that surface of the polyurethane layer farthest away from said web, by sputtering; a layer of adhesive on the exposed metal surface; and a release liner in the form of a film of polyester or the like covering, but separable from, said adhesive layer. With the web and the release liner removed, the remaining pellicular laminate is useful in shielding structures from electromagnetic radiation by applying the laminate to the surface of the structure to be shielded with the adhesive side towards the structure.

Abstract: Disclosed herein is a radiant energy reflector comprising a laminated article mounted on a contoured support. The article includes a specularly reflective layer of silver protected on one side thereof from deterioration-inducing agents by a transparent cover sheet of polymeric material, and on the opposite side thereof by a non-polymeric protective layer of substantially inert and corrosion-resistant material. Also disclosed is a method for producing the article which yields an intimate and tenacious bond between the cover sheet, reflective layer and protective layer, thus reducing the likelihood of delamination.

Abstract: An improved anti-ballistic missile warhead in which the missile structure and warhead projectiles are combined into a single entity. The structure, which may be formed of superalloy to resist heat, requires no heat shield, the outer surface being aerodynamically smooth. It is fabricated by precision casting, individual projectiles being pre-formed by casting internal cavities which delineate the projectiles for at least a substantial part of the thickness of the casting. Figuratively, the combined missile structure and warhead is in the form of a pineapple or hand grenade which is "inside out". The explosive may be cast in place or installed separately within a thin canister. Because there is no skin to pierce, less explosive is required and dispersion is substantially reduced.

Abstract: A fluid flowmeter is disclosed herein which includes a fluid displacement member positioned in the fluid flow to substantially linearize the velocity profile associated therewith. In one form of the invention the pressure differential in the fluid existing across the fluid displacement member is advantageously exploited, and several embodiments thereof are disclosed. In another form of the invention the fluid displacement member is utilized to produce trailing vortices.

Abstract: A denture-retaining unit comprises a ball and socket structure, the socket being adapted for incorporation into a denture. The ball is a sphere having a truncated portion providing a flat base adapted for magnetic engagement with a flat face of a magnetizable keeper, which keeper is adapted to be secured to a support member extending from the jaw. A characterizing feature of the unit is that it permits lateral movement between the denture in which the socket is embedded and the keeper, while the flat faces of the keeper and the sphere remain fully magnetically engaged.

Abstract: An electro-mechanical device for converting mechanical energy into electrical energy and vice versa, which advantageously utilizes the phenomenon known as contact charging. A metallic first member is urged into intimate abutting contact along a surface thereof with a surface of a second member formed from semiconductor material. The abutting surfaces of the members are each divided into a plurality of segments such that relative movement between the members, while the members are retained in abutting contact, results in the capacitance of the device varying within predetermined limits. Four preferred embodiments of the device are contemplated. In the first embodiment the area of contact between the abutting surfaces is caused to synchronously vary between predetermined limits. In the second, third, and fourth embodiments the contact area remains constant and, instead, the surface characteristics of the second member are controllably varied to thereby cause the variance in capacitance.

Abstract: A polycrystalline sample is irradiated with a collimated beam of substantially monochromatic X-ray radiation to form a diffraction come which extends and expands outwardly from the sample. A substantially planar, two-dimensional, position sensitive detector is disposed across the cone to intercept and thereby form a two-dimensional image of at least a substantial portion of the cone's cross-sectional periphery. A theoretical relationship exists between the shape of the cone's image and the residual stress in the sample such that the image can be analyzed to quantitatively determine the residual stress.

Abstract: A process for effecting flame retardation of fibrous structures, such as fabrics, particularly fabrics made from mixtures of natural and synthetic fibers, such as cotton and nylon. The process includes the steps of contacting the fabric to be treated with halomonomers and/or inorganic salts, followed by fluorocarbon grafting, and then by photohalogenation. The aforesaid treatment results in fabrics which are not only flame resistant but also have improved hand, manifested by softness, silkiness, and unwettability of the resulting fabric.
