Title: Adhesive composition for optical fibers
Inventor: MOYER WENDELL W
IPC: C09J4/02
Filed: 1986-03-25
Granted: 1990-11-06
Abstract: Abstract This invention provides a curable adhesive composition suitable for splicing optical fibers or connecting optical fibers to other optical elements which comprises a fluoracrylate having the for-mula   wherein R1 and R2 are acrylate, methacrylate or hydrogen, n is an integer of 1 through 5, and at least one R1 is acrylate or methacrylate and at least one R2 is acrylate or methacrylate. The adhesive containing the fluoracrylate may also contain a polyfunctional acrylate or methacrylate monomer having 2 to 7 acrylate or methacrylate groups, which is used to adjust the refractive index value of the adhesive composition to precisely match the optical fiber refractive index.  The adhesive com-position may also contain an acrylate or methacrylate oligomer which does not affect the refractive index and is used to adjust the viscosity of the uncured adhesive composition to the desired level.  The adhesive composition may contain a photoinitiator and be photocured.

Title: Mold for the continuous casting of beam blanks
Inventor: LORENTO DONALD P
IPC: B22C9/06
Filed: 1986-12-05
Granted: 1991-01-29
Abstract: ABSTRACT           A mold for the continuous casting of beam blanks has a central casting passage bounded by a pair of parallel walls.  On either side of the central casting passage is an expanding casting passage which widens in a direction away from the central casting passage and is bounded by a pair of inclined walls diverging from respective ones of the walls of the central casting passage.  A terminal casting passage bounded by a pair of side walls parallel to the walls of the central casting passage is located outwardly adjacent to each expanding casting passage.  The various casting passages cooperate to define a dogbone-shaped mold cavity.  The inclined walls have an angle of inclination no smaller than arc tangent (y/z) where y is the distance from a point on an inclined wall to a transverse center line of the cross section of the mold and z is the distance from such point to a longitudinal center line of the cross section of the mold.  Such an angle of inclination results in a beam blank having a shell of increased thickness, strength and uniformity upon exiting from the mold.

Patent CA-1338755-C (CA)
Inventor: WASYLYSHEN ERNEST W
IPC: G01F23/00
Filed: 1988-04-29
Granted: 1996-12-03
Abstract: The invention provides a plastic float inside a grain storage bin.  The float is a rounded cylinder having a projecting fin, and an internal mercury switch in a circuit including an external signal light fixture.  The float is suspended from the storage bin roof at a height sufficient to allow the operator loading the bin to shut off the loading equipment on actuation of the signal light.  When the grain in the bin reaches the float it is pushed away and the fin is rotated closing the mercury switch and actuating the signal light.  This allows the operator to make full use of grain bin storage capacity without spillage, and without climbing ladders to assess bin utilization.  In effect the invention gives the operator ground eye level access to the top of the bin.

A group of fingers in the continuously passing line of conveyed planting fingers are opened for receiving the plants at their stems during a first part of the second stroke and the group of fingers are closed to grasp the plants during a second part of the second stroke.  The incubating tray is extracted from the plants in the fingers during the second part of the second stroke whereby the plants are transferred to the planting fingers and held by the stem with a root bound soil mass depending from the stem.          The tray is moved away from plants within the planting fingers to prevent interference between the root bound soil mass of the plants in the fingers and the foliage of plants remaining in the tray.
