IPC: G02B6/036
Filed: 1982-12-06
Abstract: Disclosed is an optical waveguide fiber having a core (10, 12, 14) surrounded by a layer (16) of cladding material. The core is characterized in that it includes a region (14) of depressed refractive index. The inner radius ai of this region (14) is greater than zero, and the outer radius ao thereof is less than the core radius. By appropriately selecting the core index depression characteristics such as radial location, width, depth and shape, a fiber having the desired wave guide dispersion characteristics can be designed. Dispersion minimization over a wide wavelength range can be achieved, without adverse affect on system loss.

Granted: 1992-06-16
Abstract: ABSTRACT:    The assembly comprises a first insulating housing having terminal receiving through cavities each having therein a resilient locking lance, and a second insulating housing having through cavities. There projects from the front face of the second housing a row of locking lance actuating tongues.  In a terminal loading position of the housings the front face of the second housing is spaced from the front face of the first housing so that each tongue projects to some extent beneath a respective locking lance.  In this loading position, an electrical terminal connected to a lead is inserted through each cavity of the second housing into a cavity of the first housing.  The housings are then moved relatively towards one another into a terminal locking position, so that each tongue is advanced further beneath the corresponding lance to lock the terminal in the cavity.  Pawl and ratchet means are provided on the housings for locating them in their loading and locking positions.

Title: Method and apparatus for sludge collection
Inventor: COUDRIET LAWRENCE A
IPC: B01D21/18
Filed: 1992-03-31
Granted: 1998-11-24
Abstract: An upper carriage floats on the surface of a settling pond or tank of liquid containing sedimentation settled out to form a bed of sludge in the bottom of the tank.  A scraper assembly is suspended from the upper carriage by flexible cables or chains to a preselected depth in the tank.   Scraper blades supported by the scraper assembly extend downwardly into contact with the sludge bed.   The carriage is propelled on a looped cable across the surface of the tank and applies a tractive force through the suspension cables to the scraper assembly.  As the submerged scraper assembly advances, the scraper blades apply a shear force to dislodge the sludge from the bed and direct the sludge to a pump carried on the submerged scraper assembly.  The dislodged sludge is pumped through a hose from the tank.  In response to an excessive shear load applied by the sludge bed resisting forward movement of the scraper blades tending to force the leading edge of the assembly to move downwardly, the length of the leading cables is shortened to raise the leading edge to a position to permit continued shearing action of the scraper blades.
