  • Patent number: 4897972
    Abstract: A molded door and mating door jamb for a observation tower enclosure includes a projection to adapt to a non-vertical structure on one side. The door projection is provided to avoid a projecting wall structure experienced by present day door jamb structures in enclosures having glare reducing slanted windows. A generally planar door is hinged to a vertical door jamb on the opposing side, but has a triangular projection on the non-vertical, slanted window side to adapt to the slanted door jamb construction. The door is hinged to open outward and away from the observer's forward area of interest. The molded door avoids a door jamb and adaptor sections which may obstruct the guard's view as he or she opens the door and exits. The molded door can also provide additional structural support for shutters and roof structure when closed. The door can also include seals, locks and windows for added security, protection and visibility.

  • Patent number: 4892370
    Abstract: Algorithms and optical processor architectures for implementing a two-dimensional truth-table look-up processor are disclosed. An optical holographic medium stores the spectral expansion coefficients that map two-dimensional digital inputs of a binary truth-table into two-dimensional outputs of that binary truth table. Several algorithms are described using discrete orthogonal transforms such as one of the Walsh transforms (the Walsh-Hadamard transform, the Rademacher-Walsh transform, the Walsh-Kaczmarz transform) or the Haar transform. These transforms are used to find the corresponding spectral vectors and the corresponding boolean basis vector. The inner product multiplication of the spectral vector with the boolean basis vector yields the digital outputs of the binary truth-table. Another algorithm uses the Reed-Muller expansion which is a non-orthogonal transform. Various architectures of digital optic two-dimensional truth-table look-up processors are also disclosed.

  • Patent number: 4891037
    Abstract: A split tube containing a lubricant is engaging a bicycle chain. The lubricator tube is carried by the chain during the initial chain operation until the tube end contacts a barrier surface on the chain drive mechanism. The barrier may be the pivoting idler arm, the derailer mechanism, or a portion of the bicycle frame. The device brings the lubricant in intimate contact with the chain allowing the use of semi-solid, liquid, and solid-solvent mixture of lubricants.

  • Patent number: 4883658
    Abstract: A synergistic combination of an aqueous solution of a partially hydrolyzed poly(vinyl acetate) and a fully hydrolyzed poly(vinyl acetate), i.e. poly(vinyl alcohol), exhibiting a low surface tension at the water-air interface, while forming a completely wettable absorbed layer over hydrophobic solids. The combination is used as part of an ophthalmic solution including a hydrophilic low viscosity polymer, poly(N-glucose) or poly(N-vinyl pyrrolidone) with higher than normal oncotic pressure in a physiologically compatible electrolytic solution base. The formulation is effective in treating the two major underlying causes of the dry eye syndrome; ocular surface disorder and tear film abnormalities resulting in tear film instability. It can also be effective as an aqueous vehicle for topically used ophthalmic drugs or nutrients.

  • Patent number: 4872273
    Abstract: A segmented slip designed to be placed over the bottom of the spiked shoe and support the wearer so that the spikes do not contract the ground. The slip has two generally rigid segments, one at the heel and another at the sole connected by a stretch mid-segment. The rigid segments are cross braced construction, allowing spikes between braces and maximum lateral and vertical support, covered by a slip membrane. Different sizes and spike patterns at the heel and sole are accommodated by the stretchable midsection. The slip is attached to the toe and heel of the shoe by flexible caps. The slip is thick enough to allow support under load without allowing spikes/protrusions to penetrate membrane. The slip is made form elastomeric material for comfort and flexibility to adapt to various sizes. The caps also allow easy removablilty.

  • Patent number: 4869453
    Abstract: A deployed device projects through the spokes of a rear wheel and supports a bicycle from a two strut portion of the bicycle frame. A first bar member is placed between spokes and one end is hooked over a first frame strut. This first bar member bears up against the lower portion of a second parallel strut while held in place by the hooked first strut. A second projecting member is hinged at a first end to the other end of the first bar and engages the ground at the second end to support the bicycle in a nearly upright position. The projecting element is also capable of telescoping to allow adjustment to various sizes/styles of bicycles. The first bar member placement under and over struts (and between wheel spokes ) deters unauthorized use by requiring removal before wheel can be rotated. A padlock may also be provided to secure the stand/anti-theft device to the frame and/or fixed object to further deter unauthorized use.

  • Patent number: 4858410
    Abstract: A modular brickwork form for producing a regular pattern in brickwork construction. Raised ledges have concave and convex dimples to interconnect with adjoining forms, avoiding added space and deformation experienced by present day forms. The modulator brickwork form has a raised dividers and ledges to form a continuous pattern. The ledges have dimples to interconnect with adjoining modular forms without significant deformation. The lack of overlapping U-shaped edges also avoids added space between bricks and an irregular pattern of bricks. The raised ledges are also tapered to allow nesting of the forms when stacked. The forms may includes ports for drainage and corrugation for added strength.

  • Patent number: 4853630
    Abstract: Two toroidal magnets are spaced apart form each other by a ferrous spherical spacer. The spacer partially engages openings provided in the two magnet surfaces facing each other. The facing magnet surfaces have the same polarity, repelling each other. The configuration creates a stable equilibrium by conduction of the magnetic flux through the spacer and the repulsive forces at the periphery of the magnets. Four "Hall Effect" sensors are mounted to one of the magnets. These sensors detect minute changes in the device's magnetic field caused by relative rotation or other movement of the magnets. A third magnet may be added for tactile sensor applications, allowing evaluation of the pressure exerted on the device.

  • Patent number: 4852743
    Abstract: A pair of rigid frames having central openings are each covered with a pliable and stretchable material which is forced in intimate contact with a fragile article to be handled. Central openings allow passage of the fragile article which is suspended between the two pliable materials, Stretchable material and friction limits the handling shock loads which may be transmitted to the fragile article in one direction, and cushions loads in other directions. Frames can be positioned within an enclosure package so that motion of the fragile article during handling can be tolerated. A single pair of pliable covered frames can serve as packing for a wide variety of solid materials, including multiple items, with no further protection required.
