  • Patent number: 5671534
    Abstract: A razor blade assembly comprising a body assembly having a pair of body end portions and at least one cross member extending therebetween. A first U-shaped housing is provided between the body end portions, the first U-shaped housing having a scalloped edge portion formed along at least one edge thereof; a resilient foam insert is provided, at least a portion of which is disposable within the first U-shaped housing, the insert being impregnated with a lubricating material. A second U-shaped housing is provided having a plurality of fluid dispensing apertures formed therein, the second U-shaped housing being supportable by the foam insert and translatable within a first U-shaped housing, beyond the scalloped edge portion, to discharge a lubricating fluid from the resilient foam insert through the fluid dispensing apertures.

  • Patent number: 5666640
    Abstract: A microwave powered ozone producing system comprising a housing defining a microwave cavity having a volume Vo, an inlet and exhaust ports which communicate with the microwave cavity. Disposed within the microwave cavity and uniformly distributed therewithin are a number N of ozone producing lamps, each of which has a diameter D, a length L, and a nominal power p. Communicating with the microwave cavity is a microwave magnetron generator having a microwave power P and producing microwaves having a wavelength .lambda.. Electrically connected to the generator is a power supply. The optimal operating condition for the system to maximize the ultraviolet output and longevity of the lamps and minimize system power consumption is governed by the relationships:Vo.gtoreq.V min 1 wherein V min 1=8 .pi..lambda..sup.3 /3;Vo.gtoreq.V min 2 wherein V min 2=.pi.(D+1).sup.2 N L/4; and ##EQU1## wherein V min is the larger of V min 1 and V min 2, and k is a constant with a value in the range of 0.3.ltoreq.k.ltoreq.3, and .pi.

  • Patent number: 5664940
    Abstract: A gas driven pump has a housing, first and second cylinders disposed within the housing, and first and second interconnected pistons having product intake and product exhaust positions disposed within the first and second cylinders, respectively. A slide valve has first and second positions for alternately pressurizing one of the first and second cylinders and venting the other of the first and second cylinders. A linkage moves the slide valve between the first and second positions thereof in response to movement of the first and second pistons. Over-center construction of the linkage prevents stalling of the slide valve, so as to assure reliable operation of the gas driven pump. The slide valve comprises a slide for placing an inlet port in fluid communication with an alternating one of two pressure/vent ports such that the slide valve scrapes frost build up from the pressure/vent ports as it moves thereover, thereby further enhancing reliability of the gas driven pump.

  • Patent number: 5662477
    Abstract: A puppet for demonstrating the preferred positioning of oral anatomical structures (e.g., mouth, tongue, hard palate, incisor teeth) when making various audible phonetic sounds. Generally, the puppet comprises a puppet body having an upper jaw, a lower jaw, an oral cavity, a tongue, and at least one tooth extending downwardly from the upper jaw. A hand insertion passageway is formed in the puppet body and leads into a plurality of digit-receiving spaces or pouches formed in the upper jaw, tongue and lower jaw. Thus, the user's hand may be inserted into the puppet such that selected digits of the user's hand become positioned within selected ones of the digit-receiving spaces. Thereafter the digits of the user's hand may be moved or manipulated to cause the desired movement and relative positioning of the oral anatomical structures.

  • Patent number: 5661267
    Abstract: An alignment board for interfacing arrays of infrared detectors to a multi-layer module concerns an insulating board having a multiplicity of conductive vias with insulating sealing plugs and enlarged metallic pads that are attached to the ends of the vias. Preferably, an insulating layer is formed on opposing sides of the board. Openings are delineated in the layer coinciding with the metallic pads, and preferably solder contacts are deposited in the openings. A multi-layer module may be attached to one side of the alignment board using reflow solder processes. Then, arrays of infrared detectors may be attached to the opposing side of the alignment board using a lower-temperature reflow soldering process. The alignment board facilitates the interfacing and assembly of the focal plane of infrared detection systems.

  • Patent number: 5649393
    Abstract: A domed ceiling structure for attachment to an elevated support. The ceiling structure comprises a peripheral frame member which is attachable to the support frame, and a plurality of arcuate support members, each of which has first and second ends, an upper surface, and an under surface. The first ends of the support members are attached to the frame member in a manner wherein the second ends extend to a common area and the under surfaces collectively define a dome shaped support surface to which a layer of finishing material may be applied.

  • Patent number: 5649923
    Abstract: A method for conducting laser energy to a site includes steps of bringing the proximal end of a flexible tube near the site, filling at least a proximal portion of the tube with a liquid by introducing the liquid into the tube, allowing a portion of the liquid to flow out from the proximal end of the tube toward the site, and directing laser energy from a laser energy source into the distal end of the tube, whereby a portion of the laser energy emerges from the proximal end of the tube at the site. Also, such a method in which the liquid is a radiographic contrast medium. Also, such a method for removing an obstruction from a blood vessel in an animal.
