  • Patent number: 5039016
    Abstract: An improved aspiration-type chemical sprayer for dispensing small quantities of a liquid-based chemical into a stream of carrier fluid is disclosed. The sprayer includes a sprayer head assembly sealingly mounted onto a container for storing the chemical to be dispensed. The sprayer head assembly includes a multi-function unitary valve for providing a range of aspiration rates simultaneously with full communication of the container interior to atmospheric pressure. The valve may include means for positive and simultaneous closure of the aspiration and vent passages so as to seal the chemical in the container when the sprayer is not in use.

  • Patent number: 5000204
    Abstract: A portable eyeglass cleaning kit is provided with a chemically treated pig skin chamois housed within a small portable plastic storage case. The chamois is treated with a chemical mixture for more efficient eyeglass lens cleaning. The chemical fixture serves as a fungicide for inhibiting the growth of mildew while the chamois is stored in the case. The chamois can be maintained moistened in the air-tight storage case or dry to be moistened when needed. The storage case is affixed with a detachable chain which enables the unit to serve as a key chain or be attachable to one.

  • Patent number: 4993950
    Abstract: A dental connector structure has a first, transmucosal cuff member which is attached to the jaw bone or tooth root through an implant fixture embedded in the bone or tooth root, and a second, keeper member to which a denture is attached. The second keeper member is removably mounted to the transmucosal cuff. A resilient, elastic member, such as an O ring, is disposed between the transmucosal cuff and the second, keeper member to permit selected limited but substantially universal motion of the keeper member relative to the transmucosal cuff, and to absorb forces transmitted by the denture through the keeper member towards the underlying bone or root structure. The resilient elastic member also keeps the transmucosal cuff and the second, keeper member from contact with one another, and thereby minimizes corrosion. The denture includes a magnetic skirt that limits the lateral movement of the denture and the keeper.

  • Patent number: 4983415
    Abstract: An inkless method of recording an image of a desired object or symbol such as the print of a person's finger is described in which a recording surface is prepared by placing thereon a thermosensitive color-developing layer comprising a chromogenic dye such as a leuco dye, an organic acid developer, such as a phenolic compound, reactive with the dye to form a color and a thermosensitive barrier layer separating the dye and developer. A chemical reagent containing one or more metallic slats, such as ferric chloride, in the format of the desired object or symbol, is applied to the recording where the reagent reacts with the developer and/or dye in the thermosensitive color-developing layer to form a permanent two-dimensional image of the object or symbol such as the ridge pattern of the person's finger.

  • Patent number: 4932347
    Abstract: A jet ski hull includes upper and lower sections joined along a peripheral edge which edge is arranged to extend above the nominal waterline. In accordance with the present intention the lower hull section comprises (1) a central section extending from the bow of the ski to the stern thereof, 2) a concave section disposed on each side of the central section, (3) a pair of side walls joined to the upper hull section of the peripheral edge and extending downwardly and inwardly from the peripheral edge and (4) a transition section joining the lower portion of each side wall to a respective concave section. Each concave section defines a channel extending substantially the length of the hull for channeling water therethrough to prevent the hull from skidding during turns.

  • Patent number: 4917987
    Abstract: A method for enhancing fingerprint images comprises the steps of applying a chemical compound to the fingers to be printed in which the compound contains a first constituent in the form of a conventional ink or inkless reagent. The first constituent is arranged by itself (i.e., ink) or in conjunction with a developer (i.e., inkless) to provide a visible image of a fingerprint when applied to a porous surface, such as a conventional fingerprint card under light within the visible spectrum. A second constituent is included in the compound which is arranged to fluoresce within the visible spectrum (i.e., 500 to 650 nm) when subject to U.V. radiation, preferably centered at 550 nm.The compound from the fingers is then deposited onto a porous surface and a visible image is formed therefrom representing the ridge patterns of the fingers. The surface is then illuminated with visible and ultraviolet light and the fluorescence of the second constituent enhances the brightness of the image.

  • Patent number: 4913351
    Abstract: A sprinkler head having a readily accessible top plug which can be removed and replaced by a pressure-reading gauge that is in fluid communication with the head's interior pressure. Each individual sprinkler head includes a manually-adjustable pressure adjusting screw which is accessible at an exposed location for the installed sprinkler head. Pressure adjustment for an individual head, while it is operating in either a manual or an automatic mode, is available. After individual pressure adjustment for a sprinkler head has been performed the gauge is removed and the plug is replaced for normal sprinkler operation.

  • Patent number: 4897203
    Abstract: A solution of water soluble conveyor lubricant is continuously recovered from a moving conveyor through a suction bar. The lubricant is treated to reduce suspended solids, heat sterilized, the pH adjusted, and a bactericide is added. The solution is then recycled at least once to obtain about a 50%-90% recovery, and then is discharged. The process saves a significant amount of water, in addition to lubricant.

  • Patent number: RE33341
    Abstract: An automated system lifts a batch of semiconductor wafers from a slotted carrier, transfers them laterally and lowers them into a second slotted carrier. In doing this, jaws on the lifting apparatus open automatically to receive or release the wafers. With a carrier having relatively high slotted sides, such as the commonly used plastic cassette, a pusher engages the lower edge of the wafers exposed through the bottom of the cassette and pushes them upwardly sufficiently far to permit the lifter jaws to receive and lift the wafers. The apparatus is oriented at a slight angle to insure that the wafers are all arranged in precise, spaced, parallel relation so as to cooperate with slots in the lifter jaws and slots in the receiving carrier. The system has the capability to move two batches of 25 wafers to a quartz boat having 50 more-closely spaced slots, and similarly, two batches from a quartz boat may be transferred to two different plastic cassettes.
