Abstract: ABSTRACT A multiconductor electrical cable termination assembly and method of making the same having an integral structural combination of a multiconductor electrical cable, a plurality of electrical contacts, and a housing part that is molded about at least a portion of each of the contacts and a portion of the cable. Each contact forms a junction with a respective conductor of the cable, and the integral housing part is molded with the assistance of a mold core under elevated temperature and pressure con-ditions so that each of the junctions is fully encapsulated by the molded body part to create a hermetically sealed junction zone which is free of air, moisture, oxygen, and other like deleterious contaminants, and which helps to prevent the contamination of the junction when the cable termination assembly is utilized in a hostile environment.

Abstract: Low or free boron-containing glass fibers treated with amine functional organo silane coupling agents have a decreased performance in conforming to mold configurations over fibers having conventional amounts of boron and treated with aminefunctional organo silane coupling agents.          The low or free boron-containing glass fibers treated with an amine functional organo silane coupling agent are also treated with a softening agent in an effective softening amount to overcome the additional brittleness.  The softening agent in conjunction with the amine functional organo silane coupling agent provides a moisture-reduced residue on the glass fibers where the residue has a glass transition temperature of less than 30°C.  The chemical treating composition can also have one or more film forming polymers, one or more lubricants, and one or more additional coupling agents.  The film forming polymer has a glass transition temperature in the range of around 30°C to -20°C.

Title: Accumulating pallet chain-dog conveyor and method of conveying pallets
Inventor: SCHWAEMMLE KURT W
IPC: B65G19/02
Filed: 1988-01-18
Granted: 1991-07-30
Abstract: ACCUMULATING PALLET CHAIN-DOG CONVEYOR    AND METHOD OF CONVEYING PALLETS     ABSTRACT OF THE DISCLOSURE   An accumulating pallet chain-dog conveyor has spring-biased roller assemblies attached to the pallet underside for frictionally engaging dogs and spacers which are connected to an endless chain. The roller assemblies include rotatable rollers having a plurality of flats for engaging the surfaces of the dogs and spacers. In operation, the pallets are propelled by the dogs which are engaged by the spring-biased rollers. The conveyor includes a pallet stop which halts the forward movement of the pallet at a predetermined position. When the forward movement of the pallet is stopped, the opposed rollers rotate the distance of one flat whereby the dog passes between the rollers in sliding, frictional engagement therewith. Thus the pallet stops and the endless chain with its attached dogs and spacers continues to move. After the dog passes from between the opposed rollers, the rollers slidingly, frictionally engage a spacer which also passes between the rollers. This sliding, frictional engagement with the dogs and the spacers during the time in which the pallet is stationary due to its engagement with the pallet stop prevents rearward and lateral movement of the pallet.     In another aspect, the conveyor includes a pallet-propelling sprocket in synchronous motion with the endless chain and a plurality of sprocket-receiving pins mounted on the underside of the pallet. The conveyor includes a drive course and return course linked by turn courses. As a pallet reaches the end of the drive course or the end of the return course, the pallet-driving sprocket engages the pins whereby the pallet is carried through the turn course.

Title: Technique for repelling carriers in optical communications to minimize mutual interference
Inventor: FOSCHINI GERARD J
IPC: H04J14/02

Granted: 1990-10-23
Abstract: A TECHNIQUE FOR REPELLING CARRIERS IN  OPTICAL COMMUNICATIONS TO MINIMIZE        MUTUAL INTERFERENCE            Abstract The present invention relates to a technique for repelling carriers in a Frequency Division Multiplexed (FDM) lightwave communication system to minimize mutual interference between signals. The system comprises a plurality of transceivers (20), each comprising a transmitter section (30) and a receiver section (40) which is coupled to a separate user of the system on one side, and on the other side to a lightwave communication arrangement (21-23) that interconnects the plurality of transceivers. Each of the transmitter sections of the system uses a separate carrier (10-14) for transmitting an associated users' information signal, and, during each sequential test cycle period, slowly dithers this carrier in random order to a first nearby frequency (50), on one side of the nominal carrier frequency, and then to a second nearby frequency (51) on the other side of the nominal carrier frequency. Each receiver section monitors and measures the background interference at each of the first and second nearby side frequencies of the desired channel and sends a control signal back to the associated transmitter section to move the frequency of its carrier to the nearby side frequency indicating the least noise for the next testing cycle where the above technique is repeated.

Title: Connector employing mode field modification
Inventor: NOLAN DANIEL A
IPC: G02B6/26
Filed: 1988-04-22
Granted: 1992-12-15
Abstract: Abstract of the Disclosure Disclosed is a mode field modifier for use with an optical fiber having a core and a cladding of outside diameter d.   The modifier comprises a modifier core having a refractive index n1.  Surrounding the modifier core is first cladding layer having a refractive index n2 that is less than n1.  On the surface of the first cladding layer is a second cladding  layer having a refractive  index  n3  which  is  less  than  n2.   The modifier is tapered intermediate its ends whereby it has a large diameter end and a small diameter end.  The diameters of at least the core and first cladding layer at  the  large  diameter  end  are  greater  than  the corresponding diameters at the small diameter end.  The diameter D1 of the first cladding layer at the large diameter end is greater than d.  An axially disposed hole in the large diameter end receives a fiber which is held in such alignment with the made field modifier that  it  is  in light coupling relationship with the modifier core.  The mode field of a signal coupled from the fiber to the mode field modifier expands as it propagates through the tapered portion of the modifier to the small diameter end.  An in-line coupler between two optical fibers is effected by connecting together in axial alignment two such mode field modifiers with their small diameter ends adjacent one another.

Title: Fluid drop detection and discrimination system
Inventor: KAMEN DEAN L
IPC: G01V5/00

Granted: 1991-01-29
Abstract: ABSTRACT OF THE DISCLOSURE     A system and method is provided for detecting the presence of drops in a fluid drop path, such as that in a medical infusion system, and for discriminating between signals resulting from true drops and signals resulting from aberrant fluid flow.  A transducer generates a drop signal related to the presence of a drop in a fluid drop path.  Also generated is a reference quantity related to the value of the drop signal in the absence of a drop.  The deviation of the drop signal from the reference quantity is calculated, and is compared with first and second threshold values.  The results of these two comparisons are then used to determine the presence or absence of a true drop.
