  • Patent number: 5854322
    Abstract: A modified coal tar pitch useful in roofing applications, containing coal tar pitch, and a nitrile butadiene rubber, is blended by heating the coal tar pitch to a molten temperature, adding the rubber in powder form and agitating the material in a suitable high shear mixing apparatus until adequate phase inversion occurs between the polymer and the coal tar phase. After preparation, the material is cooled in containers until use, at which time it is heated to a flowable temperature and applied using a roofing mop or squeegee.

  • Patent number: 5478120
    Abstract: A publication designed to receive a photograph of a subject, such as a child, so that the subject in the photograph forms a part of the illustrations on the pages of the publication. The publication is designed to allow the subject to be identified with a particular organization of an association. For example, the publication may be designed to allow the subject to be identified as a player of a particular team within a football, basketball, baseball, or other sports league. The invention also relates to a publication produced using a computer to manipulate image data stored on a CD-ROM or the like so that the image data generic to each organization within an association can be easily enhanced and customized to depict one or more particular organizations within the association, such as one or more particular football teams within a football league.

  • Patent number: 5479222
    Abstract: The invention is directed to an ophthalmoscopic or gonioscopic lens system as well as an adapter lens systems for use with such an associated lens apparatus. The indirect ophthalmoscopy lens of the invention for use in examination or laser treatment of a patient's eye comprises a hand-held, pre-set or fixed system having at least two lens elements, each having first and second surfaces. At least one of the lens elements includes an aspheric surface of revolution. The at least two lens elements are positioned adjacent one another in a housing, such that the refractive properties of each are combined to converge light from an illumination light source to the entrance pupil of the patient's eye to illuminate the fundus thereof and form a fundus image to be viewed. The adapter lens systems of this invention are designed for use with an associated ophthalmoscopic lens, enabling selective modification of the optical characteristics of the ophthalmoscopic lens system in a predetermined manner.

  • Patent number: 5074604
    Abstract: The disclosure describes a latch retaining device to maintain the latch of a door in an inoperable position, which includes at least one body member adapted to engage and grip the door knob of the door so as to retain the door knob in its latch releasing rotated position indefinitely. The body member of the device may have first and second ends with the first end thereof adapted to frictionally engage the door adjacent the position of the door knob, whereby frictional engagement between the device and the door as well as the door knob enable the door knob to be maintained in a position to render the door latch inoperative. Alternatively, the body member may frictionally engage a door knob and exert an appropriate force thereon to maintain it in a latch releasing position. The at least one body member is secured in its frictionally engaging position by means of a cincturing strap associated with the body member.

  • Patent number: 5006837
    Abstract: A display system including a programmable video graphic controller allows for continuous smooth panning through memory which is larger than the system's video memory. The video memory is continuously updated with new image data so as to form two duplicate images within video memory. When an edge of video memory is reached, the displayed image may be shifted from one of the duplicate images to the other within video memory to allow continuous panning without the need to stop and refresh the image data every time an edge of video memory is reached.

  • Patent number: 4920638
    Abstract: There is described a method and a device for the production of a wire jointed-band of alternately clockwise and counterclockwise, respectively, wound spirals of metal wire or artificial resin wire, wherein the spirals are guided to a narrow pass such that the windings providing the spirals open themselves in the area of the narrow pass and in this the parallel spirals partly are pushed into each other such that in each case one of the windings of one spiral is placed between adjacent windings of the adjacent spiral whereby the spirals thus fitted into each other are connected with each other by inserting a coupling wire into the space provided by the overlapping windings and whereby in each case several of the pairs of spirals fitted into each other are guided to the narrow space in which area the spirals are driven in the transporting direction. This is resulting in a high production speed and broad wire jointed-bands.
