  • Patent number: 5187504
    Abstract: An eyeglass frame includes a lens frame having a pair of opposed endpieces, two hollow connectors each having one end pivoted to one of the endpieces, and two elongated bows each having one end pivoted to the other end of one hollow connector. The elongated bows are turnable relative to the hollow connectors between a first bow position, wherein the elongated bows are aligned with the hollow connectors, and a second bow position, wherein the elongated bows are positioned transverse to and inward of the hollow connectors. The hollow connectors are turnable relative to the endpieces about a generally vertical plane between a first connector position, wherein the hollow connectors extend rearwardly and horizontally from the endpieces, and a second connector position, wherein the hollow connectors extend vertically downward from the endpieces.

  • Patent number: 5177810
    Abstract: A sun shield for infants including a cap, a transparent shield, and a binding material. The cap has a strap extending downwardly therefrom and positioned in a location beyond an edge of the transparent shield. The flexible transparent shield is removably affixed to a surface of the cap and extends downwardly below an edge of the cap. The transparent shield is of a material suitable for blocking ultraviolet radiation. The transparent shield has a convexed center extending outwardly from the cap. The binding material is fastened to the transparent shield so as to cover the outer peripheral edge. The transparent shield is fastened along the inner edge of the cap by engaging corresponding sections of hook-and-loop material on the cap and the transparent shield.

  • Patent number: 5176855
    Abstract: An improved carburetor uses a butterfly air valve having a controlled air pressure difference across it and positions a tilt valve, proportionally to feed the liquid fuel with a predetermined pressure difference across the fuel valve and the metered fuel is picked up by air and fed into the main air stream below the throttle place through a small air passage.

  • Patent number: 5170820
    Abstract: A system for controlling the flow of agricultural ammonia from a tank to applicator apparatus transported by a land vehicle over the ground includes a ground speed sensor that generates a speed signal representing the speed of the land vehicle over the ground, an ammonia flow reader that generates a flow rate signal representing the flow of ammonia through the system, a throttling device having means for varying the flow of ammonia through the system, and i)computing means for sending a throttling signal to the throttling device, the computing means being responsive to the speed signal and flow rate signal to cause the throttling device to throttle the flow of ammonia through the system.

  • Patent number: 5168663
    Abstract: A laterally flexible and generally inflexible longitudinally hand-held sanding device. The device includes a generally tubular walled body of tough rugged semi-rigid resilient material which is generally cylindrical in its normal relaxed at-rest state. A longitudinal slot extends the length of the body severing the body wall to facilitate lateral flexing. A pair of spaced apart parallel angularly and inwardly extending tapered lips define the opposite sides of that slot. The sander may be flexed to accommodate a variety of contours to be sanded. It may be used in association with sheets of sandpaper or other abrasive material, or abrasive material may be embedded in the body of the sander, either at the outside surface or throughout the body.

  • Patent number: 5162029
    Abstract: A ski-deck adapted to be easily knocked down for storage or transport is provided by having telescoping side frames that secure rollers on bearings for a looped carpet over a ski deck and adjustable fitting on vertical support rails secured to horizontal support rails in order to adjust the height and slope of the ski deck. Horizontal safety rails are secured to vertical support rails for a waist belt and ski-grips with a safety switch that will stop the motor drive for the looped carpet. A motor speed control potentiometer is provided on top of a vertical support rail for the ski student's use in adjusting the simulated downhill skiing speed desired.

  • Patent number: 5162739
    Abstract: A double-tuned NMR sample excitation coil has a first end connected through a first balancing inductor to ground and a second end connected through a second balancing inductor to a low-frequency (LF) capacitor tuning and matching network. Two two balancing inductors have inductance less than 50% but greater than 10% that of the excitation coil. Each balancing coil is tuned by a capacitor network to an independent resonant frequency when disconnected from the sample coil that is less than 95% but greater than 60% of the final high frequency (HF) resonance. Moreover, both such independent resonant frequencies are equal within 10%. Broadband operation is possible under a variety of temperatures and the circuit works with high-speed sample spinners.

  • Patent number: 5159647
    Abstract: By processing the highest-resolution graphical data (e.g., image data) pertaining to relevant-objects defined by the graphical data into abstracted multiple-attribute information that is stored in a group of nodes of the lowest level of a hierarchy of data arrays (e.g., the leaf nodes of a complete data tree file), the present invention processes the data of each of these hierarchy of data arrays backward toward a single node of the highest level of the hierarchy of data arrays (e.g., the root node of a complete data tree file), to derive an attribute vector of all the abstracted multiple-attribute information at this single node. The derived attribute vector is then used to guide a search down the hierarchy of data arrays from the single node of its highest level toward at least a selected one of the group of nodes of its lowest level (which, by way of example, may correspond to the location of a likely relevant object).

  • Patent number: 5156172
    Abstract: A fastener of a hair-treating device is first slid into position adjacent a human scalp and, thereupon, is affirmatively locked on a bundle of hair in a non-slip manner. A shield attached to the fastener is opened to receive a different bundle of hair for application of a treating agent, and thereupon closed to prevent the treating agent from seeping to the balance of hair on the scalp. An independently operated bleed-guard further resists treating agent seepage.

  • Patent number: 5155307
    Abstract: This invention includes crash sensors designed to be used for frontal impact sensing and the strategies of using these sensors. It is analyzed and shown that velocity sensing or damped sernsors are desirable for frontal impact passenger compartment sensing. inertially damped sensors, with a damping force proportional to the square of velocity, is preferred for some applications. In other cases a viscous damped sensor is appropriate and in a few cases an undamped spring mass sensor will suffice. Such sensors can be made of plastic and in the shape of short housings. A preferred embodiment of this invention utilizes a swinging mass hinged to a housing as the sensing mass. Different geometries of the mass and the housing are disclosed and used to improve the performance of such sensors. These flapper mass sensors are useful for sensing frontal impacts in the passenger compartment both as primary sensors and as single or dual contact arming sensors.

  • Patent number: 5153393
    Abstract: A crash sensor for a passive motor vehicle occupant restraint system, such as an inflatable air bag or seat belt tensioner. The crash sensor comprises a tubular passageway having a central, longitudinal axis; a sensing mass arranged to move within the passageway in the direction of the longitudinal axis between a first location and a second location; a device for biasing the sensing mass toward the first location in the passageway; and a device for closing an electrical circuit when the sensing mass moves to the second location in the passageway.The invention provides methods for reducing the motion of the sensing mass and the tubular passageway in a direction perpendicular to the longitude, and/or methods for reducing the angular momentum of the sensing mass, during motion of the sensing mass in the longitudinal direction.
