Abstract: ABSTRACT OF THE DISCLOSURE      Methods for use in producing a disc-shaped record-ing master having a thin photoresist recording layer for storing an f.m. information signal with high density.  During recording, an intensity-modulated writing beam is focused onto the photoresist layer, to form a succession of spaced exposed regions arranged in a plurality of substantially circular and concentric recording tracks.  The master further includes a glass substrate having a specially prepared surface, and the photoresist layer is deposited on the surface using a technique that ensures a uniform thickness and a uniform sensitivity to the writing beam.  The peak intensity of the writing beam is selectively adjusted such that the succession of spaced exposed regions is formed with an optimum 50/50 duty cycle.  After development to remove the spaced exposed regions, the recording master is used to produce a metallic stamper that, in turn, is used to produce disc replicas.

Abstract: ABSTRACT OF THE DISCLOSURE           The material of which a cylinder-head is made must meet two conflicting requirements.  The web-part between the gas-exchange valves must be highly ductile, whereas the sealing surface between the cylinder-head and barrel must have high resistance to creep under pressure at high temperatures.  As the power-output of internal combustion engines increases, leading to increased thermal stressing of the cylinder-heads, known heat resistant cast aluminum alloys can no longer meet these requirements.  Known reinforcement with inserts made of a material more resistant to heat has the disadvantage that the joint between the parts loosens in time as a result of differential expansion of the different materials.  This pro-blem does not arise with reinforcement in the form of one or more inserts made of a precipitation hardened sintered aluminum, since the cylinder-head and inserts are made of the same basic material and thus have the same coefficient of expansion.

Abstract: ABSTRACT         A resilient plastic web exhibiting a fiber-like appearance and tactile impression and method and apparatus for its manufacture.  In a preferred embodiment, the web exhibits a three-dimensional microstructure comprising a regulated continuum of debossed areas of non-uniform cross-section along their length.  In a particularly preferred embodiment, the debossed areas comprise capillary networks interconnecting the first and second surfaces of the web, said networks being of decreasing size in the direction of said second surface to promote fluid transport from the first surface of the web to the second surface and inhibit the flow of fluid in the reverse direction.  Forming surfaces utilized to produce said webs are constructed by laminating a multiplicity of thin plates having dissimilar patterns of apertures therein to form an integral structure exhibiting properties and characteristics unachievable by prior art machining and weaving techniques.  In a particularly preferred embodiment, the individual laminae from which the laminate forming structure is comprised are produced utilizing photoetching techniques, thus making it feasible to produce nearly any desired level of intricacy in the resultant laminate structure.  Preferred means for interconnecting said laminate structures with one another without disrupting the three-dimensional pattern in the area of joinder are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           A liquid purification system, method and apparatus includes a plurality of operationally interconnected chambers.          A supply or inlet chamber is held at about atmospheric tempera-ture while other chambers of the system are held at a partial vacuum. The liquid to be purified is metered through a pressure differential between the supply or first chamber and a second chamber to induce spontaneous vaporization of the liquid.  The temperatures of the chambers are reduced sufficiently so that, in the case of water, temperature-pressure conditions in the second chamber are below the triple point so as to condense ice and precipitate impurities into another chamber from the spon-taneous vaporization.  Condensation of the vapor in still another chamber recovers pure liquid.  A temperature differen-tial mechanism operatively connected to the chambers insures that condensation of the vapor will occur.
