Abstract: PASSIVE FIBER OPTIC MULTIPLEXER                Abstract of the Disclosure A   passive,   frequency   selective,   fiber   optic multiplexer  comprises  a directional  coupler  in which a pair  of  single  mode  optical  fibers  are  accurately positioned to provide evanescent field coupling, typically by polishing a portion of the cladding from each of the fibers to place the respective cores of the fibers within the evanescent field of light in the other fiber.   The coupling  efficiency  of  a  coupler  constructed  in  this manner  is  wavelength  dependent,  and  provides  over-coupling, that is, the capability of transferring light, virtually  entirely,  back  and  forth  between  the  fibers within the coupler.   The wavelength dependent nature of the  evanescent  field  coupling  permits  multiplexing, specifically between a pair of wavelengths, one of which is coupled in its entirety from a first fiber to a second fiber,  and the other of which is essentially uncoupled.          By increasing the number of total-transfers of the light signals between  the  pair  of  fibers,  the  frequency resolution of the multiplexer may be optimized for light-signals of virtually any frequency separation.

A plurality of drive cams each sliding up and down on its own drive shaft, and each having a helical slot on its outer surface, rotate as the shafts are rotated.  Trunions extending from the trays engage the helical grooves in the cams, and they, along with the tray to which they are connected, move up or down as the cams rotate.  The sorter has improved capacity while yet per-mitting access between trays.  It is simple and positive in operation and provides sorting action in both the upward and downward movement of the cams on the driveshafts.

Abstract: ABSTRACT OF THE DISCLOSURE       A container rearranging station wherein bottles or other containers enter in single file and are discharged with several of them abreast of each other. The station is comprised of three conveyor sections running parallelism. All the sections are tilted at the same angle so as to provide a smooth inclined plane.  A supply conveyor on which the bottles arrive in single file is the highest of those on the inclined plane and runs at the highest speed of any of them.  The adjacent intermediate conveyor runs at a slightly slower speed and the adjacent lower most discharge conveyors run at a uniform but still slower speed.  Inclina-tion angles of the conveyors between the input region of the station and the output region where the containers are abreast are preferably adjustable between 8° and 11° so that the containers drift from the supply conveyor through the intermediate conveyor the discharge conveyor.  On the highest supply conveyor side there is a guide surface or deflector which is operative to deflect the containers off of the supply conveyor if they do not drift off early enough. Only bottles with exceptionally rough bottoms generally react the deflector.  Most of the containers slide off of the supply conveyor randomly before they reach the deflector. Thus, container collisions and noise are substantially reduced.

Abstract: "GUN FIRING HEAD"                 ABSTRACT OF THE DISCLOSURE    The method and apparatus for actuating a perforating gun by pressure includes a pressure actuated gun firing head disposed on the perforating gun for detonating the shaped charges of the gun.          The gun is attached to a pipe string and located downhole adja-cent  the  formation  to be perforated.   The  pressure  actuated firing head includes a housing with a plug and piston.   The piston has a firing pin adapted for engagement with the initiator of  a perforating  gun upon  reciprocation within  the  housing.          Initially,  the piston is pressure balanced until the time of actuation.  The plug is responsive to fluid pressure of a prede-termined magnitude at the time of the actuation of the gun firing head.  Upon effecting pressure on the plug, the plug unbalances the piston causing the piston to reciprocate.  Upon reciprocation of the piston, the firing pin engages the initiator to detonate the  shaped charges  of  the perforating gun.   Pressure may be effected on the firing head through the pipe string,  or the annulus,  or  both.   The  firing  head  includes  a  plurality  of passageways, as well as the plug and piston, arranged in a manner whereby should leakage of well fluids into the firing head inad-vertently  occur,  the  apparatus  is  rendered  inoperative  and therefore the firing head cannot inadvertently be fired due to the occurrence of unforeseen intervening circumstances.
