Abstract: A reduced-blocking system where a perfect shuffle equivalent network having a plurality of node stages successively interconnected by link stages, is advantageously combined with expansion before the node stages and/or concentration after the node stages in a manner allowing the design of a system with arbitrarily low or zero blocking probability. An illustrative photonic system implementation uses free-space optical apparatus to effect a low loss, crossover interconnection of two-dimensional arrays of switching nodes comprising, for example, symmetric self electro-optic effect devices (S-SEEDs). Several low loss beam combination techniques are used to direct multiple arrays of beams to an S-SEED array, and to redirect a reflected output beam array to a subsequent node stage.

Abstract: A cylindrical part having an axial slit and called a split alignment sleeve (2) is used in an optical fiber connector for connecting optical fibers to each other. The split alignment sleeve (2) is made of a ceramic material, and the characteristics of the optical fiber connector can be largely improved. 
     Since the split ceramic alignment sleeve (2), however, is brittle, its mechanical strength may be degraded, and the sleeve may be damaged during use for a long period of time. In order to proof the strength reliability of the split ceramic alignment sleeve (2), a predetermined stress is applied to it during a manufacturing inspection to perform a proof test having a criterion for ensuring not to damage the sleeve. 
     The present invention provides an easy, low-cost test method and an apparatus therefor. More specifically, since a test load is applied from the inner circumferential surface (15a) of the split ceramic alignment sleeve, the shape, structure, and assembly of the loading part of a test apparatus are disclosed, and a proof test method of the split ceramic alignment sleeve by using the test apparatus is also disclosed.

Abstract: A method and an apparatus for automatically detecting the temperature of metallic rotatable bodies (8) without establishing any contact therewith. Electro­magnetic energy is radiated by means of a transducer (B1), i.e. a solenoid in which an alternate current is passed, towards the surface of the metallic body (8) where induced currents are generated. The thickness of material pene­trated by said currents is inversely proportional to the frequency of the solenoid current. The impedance va­riations in the material are detected by said solenoid (B1), and the relative signal is supplied to a computer (12) di­scriminating the signal relative to a resistivity va­riation of the same material, thus deriving the tem­perature of the body (8).

Title: Solid state 360 degree viewing system.
Inventor: LANG PAUL W
IPC: G02B27/64
Filed: 1990-01-26
Abstract: A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates a black and white image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A liquid crystal display (LCD) screen is utilized to define a filtered viewing window which is continuously redefined at sequential intervals to remain continually aligned with the rotating real image in space. The LCD screen includes normally opaque red, green and blue filter panels which operate to give color to the real image in space.

Title: Tower packing cartridge.
Inventor: PERDERSEN GEORGE C
IPC: B01J19/32
Filed: 1990-03-22
Abstract: A tower packing cartridge is formed of strips of fabric-like material placed in face-to-face contact such that the planes of the strips are parallel to the general flow direction through the cartridge. The fabric-like material is formed of generally straight, relatively stiff strands of mono-filament material, arranged in a repeating pattern which is preferably generally triangular in cross section in both directions. The construction provides a substantially non-nestable structure when strips are placed in face-to-face contact, such that the cartridge has an extremely high void fraction. The fabric-like material, in itself known, when assembled in this manner, achieves unique and surprising results in relation to exceptional uniformity of flow distribution across the entire face of the cartridge while at the same time maintaining extremely high void fraction to keep energy losses at a minimum during operation.

Abstract: An integrated combination isomerization and liquid phase adsorptive separation process for C₅ and C₆ hydrocarbons is given increased efficiency and cost effectiveness while also improving the product quality by eliminating the columns for the sepaation of desorbent material from extract and raffinate streams. In this arrangment a C₅+ naphtha stream (10) is split into a heavy hydrocarbon stream (14) comprising normal hexane and higher boiling hydrocarbons and an isomerization zone feedstream (18) comprising isohexane and lower boiling hydrocarbons. The heavy hydrocarbon stream (14) goes directly to a deisohexanizer column (16). The isomerization zone feedstream (18) is combined with the extract stream (20) from an adsorptive separation section (30) to form a combined feed (24). C₅ and C₆ hydrocarbons in the combined feed (24) are isomerized (26) and passed directly into the adsorption section (30). In the adsorption section (30) normal hydrocarbons are selectively adsorbed on an adsorbent material, and a raffinate stream (32) comprising desorbent and isoparaffins is passed to the deisohexanizer column (16). A desorbent stream (30) is recovered as a side cut from the deisohexanizer column and supplies the desorbent (40) for the adsorption section (30). Any desorbent (22) in excess of that required for the adsorption section is combined with the isomerization zone feed (18). The extract stream (20) that is combined with the isomerization zone feed (18), is recovered from adsorption section (30). A bottoms stream (38) comprising C₇ and higher boiling hydrocarbons is withdrawn from the bottom of the deisohexanizer column (16). A high octane isomerate (34) is taken overhead from the deisohexanizer as a product stream.

Abstract: A surgical trocar access sheath (10) having a laterally expandable retention mechanism (17) for percutaneous insertion through a body cavity wall. The expandable retention mechanism is positioned about the distal end of the sheath for retaining the access sheath within the body cavity. The access sheath has an inner elongated member cannula (19) and an outer elongated member tube (13) having a slick surface for ready insertion through a puncture site. The laterally expandable retention mechanism includes a plurality of strips (18) extending and formed longitudinally in the outer tube. The retention mechanism has an expanded state and a retracted state. In the expanded state, the longitudinal strips extend radially from the outer elongated member tube to engage the interior surface of the body cavity wall. The expandable retention mechanism is actuated by sliding an actuating mechanism hub (26) attached to the distal end of the outer elongated member tube against another hub (23) fixedly attached to the inner elongated member cannula. To insert or retract the access sheath through the cavity wall of a patient, the physician squeezes the actuating mechanism hub against the fixed hub to collapse the longitudinal strips against the surface of the inner elongated member cannula. Once inserted, the actuating mechanism is released to expand the retention mechanism.
