Abstract: Abstract of the Disclosure The invention provides a protective casing for a cube-shaped modular ceramic heat exchanger core, in which the core can easily be installed without danger of leakage between the fluid paths of the core, either while the device is new as its temperature changes, and subsequently as it is in use subjected to drastically altering operating temperature.  Moreover, the core  can easily be replaced by a core of different heat transfer ability without diminishing the ability to prevent such leakage.  To this end the core rests in the casing with the edges of one face engaged with a suitable ceramic fibre composition gasket;  the opposite face of the same flow path as engaged by another such gasket and the gasket is in turn engaged by a gasket compression member.  The compression member is urged into this engagement by strong springs which thereby  hold the gaskets in the necessary sealing engagement.  Preferably the body of the protective casing is of refractory material, and may be enclosed by a supplementary outer metal casing  The exchanger may be used as a heat reclaimer receiving through one path the outlet flue gas of a high temperature furnace, and through the other path the combustion air for the furnace hot air burner.          Preferably the gasket compression member is located  at the inlet for the combustion air, which is the coolest location.  The invention also permits the production of an integral burner/ recuperator assembly without the need for heavily insulated connections as in the prior art.

Abstract: ABSTRACT OF THE INVENTION    A hollow fiber separatory element of the type having a plurality of hollow semipermeable fibers terminating at their end portions in resin tubesheets; each tubesheet has a disc-shaped portion that tapers radially inwardly toward its inner end surface that serves as a pressure-induced sealing surface when forced into contact with a correspondingly tapered surface on the inner wall of a surrounding jacket. Each tubesheet optionally includes a second tapered portion that extends outwardly from the outer end face of the disc portion and its peripheral surface tapers radially inwardly toward the outer end planar surface which exposes the open ends of the fibers therein. The tubesheet disc portion may be circular, lenticular, elliptical or have other selected shape.     The invention includes a hollow fiber medical separatory device which incorporates the new separatory element by a pressure type mechanical seal between the inner end surface of the disc portion of the tubesheet and a radially and axially inwardly extending tapering inner wall surface of the surrounding jacket of the device.     The improved method relates to forming the new separatory element tubesheets by centrifugally casting a thermoplastic resin around the ends of the fibers in unique molds which enable uniform resin penetration and fiber wetting, and solidification of the molten cast resin into a sound and substantially void-free tubesheet having selected tapers.

Abstract: ABSTRACT OF THE DISCLOSURE        Apparatus for determining the direction a lens should be moved in order to provide a proper focus of a remote object on a predetermined plane.  A plurality of radiation detectors are positioned to receive radiation in first and second patterns from the object and to produce signals in accordance therewith.  A first group of radiation detectors, produces signals indicative of the radiation received on the first pattern while a second group of radia-tion detectors produces signals indicative of the radiation received, in the second pattern.  The two patterns coincide at the proper focus but at other than the proper focus position, the two patterns are spaced from one another in a direction which depends upon the direction the lens should be moved to achieve proper focus.  The absolute value of the difference between the signal from a first detector in the first pattern and the signal from a first detector in the second pattern is compared with the absolute value of the difference between the signal from a second detector in the first pattern and the signal from a second detector in the second pattern.  The result is summed over a predetermined range and a characteristic of the summed value is indicative of the direction the lens should be moved for proper focus.

Abstract: ABSTRACT OF THE DISCLOSURE     Timing errors in a color television signal equal to a fraction of the nominal period of one cycle of color burst are corrected by clocking an analog-to-digital converter during each horizontal line interval of the television signal with two clock signals having the same nominal frequency equal to a multiple of that of the color burst.  During the color burst interval of each horizontal line, the analog-to-digital converter is clocked by a stable time base reference clock signal and the obtained digitized color burst is stored in a recyclable digital memory.  Following the color burst interval, the stored digitized color burst is regenerated for the remainder of the horizontal line and a clock signal derived for use in clocking the analog-to-digital converter.  The digitized television signal provided by the analog-to-digital converter is written into a clock isolator at times determined by the clock signal derived from the digitized color burst and, thereafter, read from the clock isolator at times determined by the reference clock signal.  Timing errors exceeding the nominal period of one color burst cycle are corrected by writing the digitized television signal from the clock isolator into a following random access memory and incrementally adjusting the memory's read time in accordance with such errors measured in steps equal to the period of one color burst cycle.          The stable time base reference clock signal is coupled to control the signal processing following passage through the clock isolator.

Abstract: ABSTRACT OF THE DISCLOSURE      A single fiber connector for a pluggable card or module optical interconnection is formed of a connector socket that may be mounted to a printed circuit card or optical module and a connector pin that is  attached to a housing or a suitable bulkhead by which the printed circuit card or optical module is to be supported.  Each of the connector socket and the connector pin has an internally threaded axial bore for receiving and retaining a single optical fiber cable coupler from the end of which an optical  fiber strand extends.  Each pin and socket includes 2 further precision bore through which the fibers pass to abut end-to-end in the precision bore of the socket.  The socket further has a tapered end male section that is inserted into a corresponding tapered end female section of the pin, with the fiber held by the pin being automatically guided into the precision bore of the male section of the socket as the printed circuit card or module is inserted into the connector on the bulkhead.    To effect this automatic guidance of the fibers together, a bracket is mounted on the printed circuit card for holding the connector socket.  The bracket is dimensionally positioned relative to the end of the card so that when the card is mounted on the bulkhead through associated hardware, such as electrical pin connector support units, the optical fiber connector and socket will be properly dimensionally located for alignment and fiber coupling.
