Both regions are arranged in patterns with a size and interval corresponding to that of water drops.

Abstract: Thin-walled, high-strength prophylactic sheaths fabricated from elastomeric polymer materials are augmented along the border at the open end with a resilient material having a 100% tensile modulus substantially lower, preferably lower by at least about 75%, than that of the sheath material. This facilitates the rolling of the edge and stretching of the sheaths for purposes of application without compromising the high degree of sensitivity in terms of heat and sensation transmission associated with the thin-walled sheaths themselves.

Abstract: An optical disk includes two disk substrates bound together with a spacer in between and at least one of the substrates has a recording layer facing the inside. Before using the adhesive, the portion of the recording layer in the bonding area is removed so that the adhesive is applied directly between the spacer and a transfer layer which has been formed on top of each substrate. The bonding inside the disk is much stronger and peeling of the disk is prevented.

Abstract: A backup board for use when drilling through a circuit board having a conductive layer therein, the backup board comprises a lamination of outer planar sheets, and an inner core of a double wall corrugated material, the outer sheets being impregnated with a thermosetting adhesive, the sheets and the core being subjected to heat and pressure to form a laminate where said corrugations fold over and bond to said outer planar sheets, to provide a backup board giving surface support by said outer sheets with a less rigid core therebetween.

Abstract: A packet for absorbing and immobilizing a liquid including an envelope which is degradable in the liquid and a liquid absorbing and immobilizing material in the envelope. One or more of a biocide, fungicide, antimicrobial, bacteriostat, sanitizer, disinfectant, scent or deodorizer is added to the liquid absorbing and immobilizing material for treating the liquid which is absorbed. The envelope has a dot matrix coating of heat-fusible material on degradable starch paper. The dot matrix coating permits heat-sealing of the envelope leaving the uncoated portions of the starch paper to degrade in solutions in which the dot matrix coating is insoluble.

Abstract: This invention relates to reduced base-content chewing gum compositions containing an anesthetic active. These compositions release sufficient amounts of the anesthetic to provide an anesthetic effect in the mount and throat areas without significant bitterness or off-note taste. Hexylresourcinol is the preferred anesthetic.

Abstract: The invention relates to novel aerosol formulations comprising LHRH analogs, a lipophilic counterion, solvent and propellant and, optionally, surfactant, valve lubricant, an antioxidant and flavor and fragrance.

Abstract: A selected pattern of conductor runs is formed on a sheet having a surface layer of dielectric material, by forming an electrostatically charged image of the selected pattern on the surface layer. Toner powder, comprising core particles of conductive material coated with fusible dielectric material, is deposited on the surface layer and is fused to the sheet.

Abstract: This invention discloses a covering comprising a floating member shaped as a square loop, one pair of opposite portions of which are inflatable members, and a water-proof sheet having a nipple downwardly formed thereon, which is loosely stretched inside the square ring of the floating member and the peripheral edge of which is tightly connected with the same. The covering can float on the water and shield the water from scorching sunshine, killing frost, strong wind and acid rain. It is adaptable, therefore, to be used in nursery pool to protect the crops raised therein from damage by extraordinary weather.

Abstract: A dispenser for use, for instance, as a rumen bolus is a generally cylindrical container (1) for material to be dispersed into the digestive tracts, etc. of a ruminant. The container has a closure (3) held in place by a controlled release glass (CRG) member (5). When this member is dissolved, the closure (3) comes out and the contents are released. The cylindrical container can be formed by a hole in a larger member which has several such holes so that different materials can be released, or materials released at different times.Variants include stacked arrangements in which several dispenser compartments are coupled so that as one is emptied a CRG member is dissolved to release material in the next compartment.In some cases the CRG member acts both as the release device, and as the closure for its compartment, and in others it also acts as a means of linking a number of detachable sections.

Abstract: Oral garlic preparations contain garlic powder as well as the enzyme allinase, in which each of the components is spatially separated from the other and are recombined only after having been orally administered.

Abstract: A recording paper for use with recording meters comprises a first section having transmission areas for transmitting the driving force of sprockets or the like in the recording meter to the recording paper, and a recording area in which data is recoreded, and a second section, which does not have transmission areas. The transmission areas contain sprocket holes which are engagable with sprockets, while the second section does not have sprocket holes. The recording meter transmits the driving force of the sprockets to the recording paper through the transmission areas, to convey the recording paper and records data on the recording paper while it is being conveyed. When the second section of the recording paper reaches the sprockets, the sprockets run idle, due to the second section not having transmission areas for enabling the driving force of the sprockets to be transmitted to the recording paper.

Abstract: Flexible circuits are obtained in an elegant manner, without the customary etching methods, wet-chemically in accordance with the principles of semiadditive or fully additive technology by using for the activation noble metal activators and, as base material, films or flexible boards whose surface has (a) a specific total pore volume per unit area of 0.015-0.045 dm.sup.3/ m.sup.2, (b) an average pore diameter of 0.05-5.0 .mu.m and (c) an average pore depth of 0.05-4.0 .mu.m.

Abstract: A modified printed wiring board for reducing the cracking of solder joints used to attach ceramic leadless chip carriers to the surface of the printed wiring board. A relatively thin expansion layer is provided on top of the conventional printed wiring board. This expansion layer is bonded to the printed wiring board except at locations underneath the footprint of the chip carrier and solder joints. This expansion layer reduces the stress on solder joints between the ceramic leadless chip carrier and the printed wiring board due to thermal expansion mismatch, to thereby reduce cracking of the solder joint. Prevention of bonding underneath the chip carrier footprint is provided by a thin layer of polytetrafluoroethylene (PTFE). Methods for applying ther PTFE layer are disclosed.

Abstract: There is disclosed a method of producing a transition metal pattern on a glass or glass-ceramic substrate by selective exudation of a transition metal from a glass substrate containing the metal as an oxide. The selective exudation is effected by applying an intense, well-focused source of energy to a glass in a pattern corresponding to the desired metal pattern. This develops localized heating, and thereby causes corresponding localized metal exudation from the glass. The metal pattern may be rendered electroconductive, and may constitute a pattern of interconnecting lines for microcircuitry.
