Abstract: METHOD AND APPARATUS FOR DETERMINING THE   SATURATION TEMPERATURE OF A SOLUTION                                ABSTRACT          Method and apparatus for determining the saturation tem-perature of a solution. In an optical measurement vessel, the tem-perature of a sample of the solution is gradually decreased until crystals are formed and subsequently gradually increased until the crystals dissolve. The temperature is measured continuously and the formation and dissolving of the crystals is detected optically by means of a beam of polarised light which is transmitted through the measuring vessel, and passed through an analyzer the direction of polarisation of which is normal to that of the beam of light, and detected by a photodetector behind the analysator.         Only when a small amount of optically active crystals is pre-sent in the solution, in which the direction of polarisation of the light is rotated, the photodetector measures a certain light inten-sity. The moment the last crystals, upon heating, dissolve is detected by the drop of the measured light intensity to a minimum value. The temperature of the solution at that moment is the saturation tem-perature of the solution.         Preferably the beam of polarized light is generated by means of a laser. For monitoring the transmitted beam, a beam splitter may be mounted in front of the analyzer, which casts part of the transmitted light onto a second photodetector.

Abstract: ABSTRACT OF THE DISCLOSURE An elevator system having a plurality of eleva-tor  cars  and  supervisory  control  for  directing  their movement in a building to efficiently serve the floors therein.  The supervisory control divides the floors and service  directions  therefrom,  called  scan  slots,  into sets, with a set being those scan slots served by the same combination of cars.  The scan slots are assigned to the elevator cars using a predetermined strategy, with the sets being taken in a predetermined order determined by the number of cars enabled to serve the sets.  The strat-egy breaks out of the rigid set concept when assigning scan  slots to cars based upon car calls,  to effect a significant improvement in elevator service.

Abstract: ABSTRACT           A bumper assembly comprising a fastener device for attachment to a sheet having a rectangular opening formed therein and having a shank having tool engaging means at one end thereof for rotation of the fastener device about the centerline of the shank.  An elongated flange extends across the opposite end of the shank at right angles to the centerline of the shank.  A circular flange is disposed around the shank and spaced below the elongated flange.  A pair of arcuate shaped cam portions are disposed on the circular flange facing the elongated flange.  The portion of the shank between the circular flange and the elongated flange has a pair of arcuate surfaces and a pair of shoulders.  The elongated flange is dimensioned for inser-tion into the rectangular opening formed in the sheet which has a thickness of less than the distance between the elongated flange and the circular flange, such that inser-tion of the elongated flange into the rectangular opening and rotation of the fastener device through 90° causes the cam portions to fall into the rectangular opening to lock the fastener in place with the shoulder surfaces inhibiting further rotation of the fastener.  A sleeve of elastomeric material is disposed around the shank and extends from adjacent a tool engaging part to a point adjacent the circular flange.

Abstract: ABSTRACT OF THE DISCLOSURE    A chop saw pivotably mounted for movement between a raised rest position and a lowered operational position, having a motor driven saw-blade rotatably supported about a shaft, with a saw housing partially encasing the saw-blade and a swinging blade guard which covers the exposed segment of the saw-blade when the saw is in the rest position.  When the saw is lowered to its op-erational position, a linkage system comprising four effective levers and four hinges clears the blade guard, thereby exposing the saw blade to the work piece.  To accommodate changing the saw blade while the saw-unit is in its rest position, the effective length of one of the levers can be temporarily reduced, thereby clearing the blade guard from the exposed section of the saw blade.  This provides easy access to the saw-blade to be changed.
