Abstract: A composition by volume of 50% water, 42% hydrogen peroxide in a 3% solution and about 8% “Dawn” detergent when applied to insect residues spattered on vehicle surfaces is very effective in removing these residues. The composition is particularly efficient in removing Plecia nearctica, or “lovebug” debris from these surfaces in a manner that does not harm the vehicle finish, is inexpensive, environmentally acceptable and safe to handle.
Abstract: The bib has a neck portion with a neck hole that is large enough to fit comfortably around the wearer's neck. The neck hole has an opening that can either be pulled over the wearer's head by means of an elastic material, or divided into an exposed strip of fabric and a coextensive underlaying strip of fabric. These strips of fabric are releasably fastened together. An expanse of protective material extending from the transverse end of the neck portion prevents food and drink from staining or soiling the wearer's clothing during the course of hand feeding. Beneath the expanse of protective material is a first layer of absorbent material. This first layer overlays a lower, second layer of absorbent material. The first and second absorbent layers offer a face wipe to the user for removing food from the wearer's face.
Abstract: A method and apparatus for applying a fluid preservative to wood or wood products has a work tank for maintaining a predetermined concentration of preservative in the fluid. The work tank is equipped with a heater to keep the temperature of the fluid and the preservative in the work tank at a predetermined level. Hot fluid and preservative is drawn under a vacuum, initially from the work tank. On filling a pressure vessel, a pressure pump then supplies the preservative and fluid mixture under pressure to the pressure vessel in which the wood or wood product is being treated. As the treatment process depletes the preservative in the fluid, through absorption in the wood, the depleted fluid is circulated back to the work tank where it is heated and more preservative is added to restore the concentration of preservative in the fluid to a desired level. The fluid, replenished with preservative, is then pumped into the pressure vessel.
Abstract: A method for not only preserving cellulose material from deterioration and from fire, but also for producing plywood, chip and particle aborad with an inexpensive and environmentally acceptable adhesive is described. The cellulose material is processed by spraying, immersing or being subjected to vacuum and pressure application in two steps. One step processes the cellulose material with a sodium silicate preservative solution. Another step processes the cellulose material with a gaseous carbon dioxide. Pressure application, moreover, can be varied in a range not to exceed 250 psi to improve product quality. Moistened cellulose material, treated in the foregoing manner, is coated with a comminuted protein, e.g. soybean meal, and pressed into a cellulose product, typically plywood and chip board.
Abstract: A breast pump for continuously applying warmth at a temperature of not more than about 105 degrees Fahrenheit to a mammary gland both before and during milk withdrawal is described. The apparatus enables the mammary gland tissue to be raised to a temperature that makes milk withdrawal more comfortable, whereupon suction is applied to the gland, as the temperature is maintained in order to commence the withdrawal process and permit the milk so extracted to be administered artificially to a suckling infant.
Abstract: The invention is an improved sports racket comprising streamlined transversal strings and streamlined longitudinal strings with surface indentations that permit the strings to lock into each other at the string crossings so the strings do not move with respect to each other and also stay oriented so as to minimize wind resitance during the swinging motion of the sports racket before and after ball contact. The invention includes fixing means for assembly of the strings in the sports racket.
Abstract: A mold for making bathtubes is disclosed. The mold includes a mold receptor and an insert attached to the mold receptor face. The mold receptor receives a shell which has a finish side and a non-finish side. The shell is placed in the mold receptor leaving a void between the non-finish side of the shell and the face of the receptor. The insert is attached to the face of the mold receptor to reduce the cross-sectional area of a portion of the space between the shell and mold receptor face. A male mold engages the finish side of the shell, sealably retaining the shell to the mold receptor. A polymeric foam material is introduced into the void between the receptor and the shell. The polymeric material fills the void and coats the shell. The molded bathtub is then removed from the mold receptor after the male mold has been removed. The insert is then removed leaving an area of reduced thickness and a periphery on the non-finish side of the molded bathtub which defines a lip.
