Title: Stamped precision lightguide interconnect centering element
Inventor: PATTERSON RICHARD A
IPC: G02B6/38
Filed: 1989-04-15
Granted: 1999-05-01
Abstract: Elements for making butt splices in optical fibers are simplified when formed of a deformable material and formed to define three surfaces (18,23,30) for contacting the fibers to be spliced. The surfaces are formed between two legs (20,21) of an element such that when the legs are closed onto the fibers the surfaces center the fibers and afford a resilient spring compression reserve force on the aligned fibers to maintain them in contact and the fibers are depressed into the surfaces slightly to center the fiber cores. Should one fiber be larger than another, the surfaces will deform sufficiently to clamp onto both fiber ends and be deformed even by the smallest of the two fibers. Thus, the splice element 11 will center the cores of the optical fibers such that in aligned position 90% or better of the surfaces of the core portions be aligned.

Abstract: A process for the optical resolution of racemic 1,4-dihydropyridines, containing isothioureido groups. Salification of racemic isothioureas with optically active acids produces diasteroisomeric mixtures of isothiouronium salts, that, using conventional techniques, are separated in the individual components to give optically pure isothioureides of 1,4-dihydropyridines and salts thereof with conventional acids. Said optically pure 1,4-dihydropyridines can then be subjected to desulphuration and to different transformations to give other enantiomerically pure and therapeutically useful 1,4-dihydropyridines.

Inventor: KENNETH A PELLEY
IPC: B05B15/04

Granted: 1999-10-01
Abstract: An apparatus and method for applying particulate powder material to a moving fibrous substrate (58) is disclosed. The apparatus includes a volumetric dry material feeder (22) for forming a continuous stream of particulate powder material. The continuous stream is then transmitted through a nozzle (38) and exits at an outlet (42) thereof. The nozzle is movable between a first and second position (47, 49) by a motion control. The motion control includes an adjustable differential gear box and an encoder for synchronizing the dispensing of powder at a predetermined location of the substrate. A flow separator (41) is disposed beyond the outlet (42) of the nozzle (38) and intermediate of the first and second positions (47, 49). In operation, the motion input drives the nozzle (38) to oscillate between the first and second positions (47, 49) at a variable speed over each product cycle. As the nozzle (38) crosses a plane of the flow separator (41), the continuous stream of particulate powder material exiting the nozzle (38) is split into two intermittent streams of particulate powder material. The first intermittent stream is applied to a predetermined location of the moving fibrous substrate (58) to form a layer of particulate powder material within a predetermined portion of the substrate (58). The second intermittent stream is recirculated back to the volumetric dry material feeder (22). <IMAGE>

Title: Vector converter
Inventor: CHUN SUNG-MOON
IPC: H04N7/015
Filed: 1992-12-31
Granted: 2000-06-01
Abstract: PURPOSE: A vector converter is provided to converts a motion vector transmitted through a DATV channel into a form being adapted to a MAC filed for enhancing a motion compensation compatibility of a motion vector obtained from an HD-MAC in an MAC field in a decoder for performing a DEMCCI method for decoding a motion compensated compatibility improvement(MCCI) again. CONSTITUTION: An HD-MAC multiplexer(11) converts an HD-MAC signal into a D2-MAC signal and outputs the signal. An ITT D2-MAC decoder(12) makes a D2-MAC screen to be watched by a D2-MAC receiver, and separates wanted signal through a demultiplexer(15), and transmits a motion vector and mode information to a DATV decoder(14), and transmits an image signal to a decoder(16) having an enhanced compatibility. The decoder(16) performs a DETCI and a DEMCCI based on the motion vector and mode information restored from the DATV decoder(14). The signal is transmitted to an HD-MAC BRD(17) and completely restored as an HD-MAC signal. A screen of an HD-MAC receiver(19) is displayed through a display conversion unit(18).
