Abstract: ULTRAVIOLET RADIATION AND BLUE LIGHT BLOCKING  POLARIZING LENS                               ABSTRACT A lens (10) that substantially blocks horizontally polarized light and selectively blocks wavelengths between 300 and 549 nanometers. The selective blocking is controlled by a sharp cut-on filter (14) selected to cut-on at either 450, 500, 515, 530, or 500 nanometers. The specific blocking and cut-on point selected is dependent upon the ultimate usage/environment of the lens (10). If a 450 cut-on filter is selected, wavelengths between 300 and 449 nanometers are blocked before a cut-on occurs at 450 nanometers; similarly, a 550 cut-on filter blocks wavelengths between 300 and 549 nanometers before a cut-on occurs at 550 nanometers. The lens (10) also allows 30 to 40 percent of wavelengths over 625 nanometers to be transmitted. The filter (14) in combination with the polarizer (16) blocks harmful Ultraviolet radiation and blue light. While a beneficial and calming effect is achieved by wearing only blue-blocking lenses, the addition of the polarizer (16) substantially enhances the calming effect and the improvement of vision without visual discomfort.

Title: Seal for a dosage dispenser tube
Inventor: FORD JOHN
IPC: B65D83/00
Filed: 1988-07-19
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE A dispenser for dispensing metered amounts of a viscous material includes a rigid tube which defines a compartment for the material, a discharge passage at one end of the tube, a push button activated and reciprocatingly movable rod which moves back and forth between two positions in the tube, and a sealing plunger which moves step-wise on the rod, from the push button end to the discharge end.  Each activation of the push button expels a metered amount of the viscous material. The plunger is formed of a short inner tube section which makes sealing contact with the rod, an outer tube section which is in sealing contact with the interior surface of the tube and a radially extending, ring-shaped, rib which connects the two sealing tubes to one another.  In a preferred embodiment, the radial cross-section of the plunger exhibits and H-shape.  A metallic gripper is secured to the plunger and has a free end which is inclined toward the rod.  When the rod is pushed forwardly the gripper bites into the rod causing the plunger to be carried forwardly with the rod to discharge a metered quantity of the viscous material.  However, on the backward stroke of the rod, the interengagement with the gripper is lost permitting the plunger to remain in place.

Title: Bag construction and bag pack utilizing the same
Inventor: PRINCE CARLTON C
IPC: B65B43/14
Filed: 1988-07-27
Granted: 1992-02-04
Abstract: BAG CONSTRUCTION AND BAG PACK UTILIZING THE SAME     ABSTRACT OF THE DISCLOSURE       A plurality of bags, each having an upright handle at either lateral edge thereof, is formed into a bag-pack, and the bag-pack is retained on a supporting rack by providing upright slits in the handles of each bag through which arms of the supporting rack extend.  Unlike holes which are formed in the bag  handles,  upright  slits do not cause weakening of the handles.   In addition,  the stacked handles of the bags are punched with a heated pin having a diameter no larger than approximately three thirty-seconds of an inch, to weld together the stacked handles of the bags, thereby permitting convenient mounting of the stacked handles on the arms of the supporting rack, without substantially weakening the bag handles.  The in-dividual  bags  are  readily  detachable  from  the  bag-pack, because the pin  is uniformly heated by being placed in a passageway in a block of metal heated to a temperature in the range of about 250-260- F.  The block passageway is long enough to receive at least a forward portion of the pin corresponding in length to approximately the stacked height of the bag-pack.

Title: Pivoting multiple clothes hanger
Inventor: ROESCH WILHELM
IPC: B65D27/00
Filed: 1988-09-23
Granted: 1992-03-31
Abstract: Abstract A clothes hanger that can be used as a multiple clothes hanger is provided with more than one supporting rod, preferably five supporting rods, all of which are U-shaped, and each of which is so guided as to telescope with the upper rod in the carrier, when a limited horizontal movement is made possible and simultaneously  it is possible for it to pivot about the longitudinal axis.  Such a clothes hanger can be hung from the clothes rail within a closet without any problem, so that then two or more supporting rods of this kind can be arranged adjacent to each other, the distance between them being so close that a number of garments can be stored in the smallest amount of space.  When one of the supporting rods is withdrawn, the remainder of the supporting rods that remain in their positions act as a counterbalance, so that the whole packet remains hanging in the optimal position in the same plane and is thus easily accessible, which fact is enhanced by the movability and telescoping capability of the supporting rods.

Title: Scatter symmetrization in multi-mode ring laser gyros
Inventor: RAHN JOHN P
IPC: G01C19/64
Filed: 1988-12-16
Granted: 1991-11-26
Abstract: SCATTER SYMMETRIZATION IN MULTI-MODE RING LASER GYROS               Abstract Disclosed herein is a method and apparatus for achieving scatter symmetrization in a multi-mode non-planar ring laser gyro.  The retro scatter effect which results in scatter coupling in each of the left and right circular polarized sets of beams is equalized, so that the scatter coupling may be common-mode rejected during the analysis phase of the ring laser gyro operation.  This equalization is achieved by unique orientation of the mirrors and the non-reciprocal polarization rotator.  The non-reciprocal rotator which may be a Faraday rotator, is rotated in such a manner that its angle of rotation relative to an angle fixed at the plane of incidence of one of the mirrors of the leg is proportional to the positioning of the rotator along the axis between the mirrors of this leg.  In this manner equal scatter coupling will occur in the left and right circularly polarized light and this scatter coupling may be common-mode rejected for purposes of deriving accurate rotational information.    Scatter symmetrization is also achieved by con-figuring the mirrors in legs of equal length so the amount of image rotation attributed to each leg is proportional to the leg length.

Title: Fuel injected two cycle engine with progressive throttle linkage for improved resolution of throttle position sensor
Inventor: HENSEL ROBERT J
IPC: F02M51/02
Filed: 1989-04-11
Granted: 1993-08-31
Abstract: ABSTRACT        A two cycle crankcase compression fuel injected internal combustion engine has a first set of one or more throttle valves controlling combustion air flowing into the crankcase, and a second set of one or more throttle valves also controlling combustion air flowing into the crankcase.  A throttle position sensor is coupled to the first set of throttle valves and controls fuel injection according to throttle position.  Increased resolution of sensed throttle position at low engine speed is provided by admitting combustion air only through the first set of throttle valves and not through the second set of throttle valves at low engine speed for an initial given range of motion, such that greater movement of the first set of throttle valves is required to obtain a given amount of combustion air flow for a given engine speed, prior to opening the second set of throttle valves, to provide more accurate fuel injection and better driveability. Progressive throttle linkage is movable to open the first set of throttle valves through a given range of motion prior to opening the second set of throttle valves.
