Abstract: Sarkar ?     METHOD OF MAKING LARGE DIAMETER    OPTICAL WAVEGUIDE PREFORMS     Abstract of the Disclosure A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass bait tube.  As the reactants flow through the bait tube, a hot zone traverses the tube to cause the deposition of sooty reaction products in the region of the hot zone.  A baffle tube extends into that end of the bait tube into which the reactants flow. The baffle tube, which traverses the bait tube along with the burner, ends just short of the hot zone so that no soot is deposited thereon.  A gas flowing from the baffle tube creates a gaseous mandrel which confines the flow of reactant vapors to an annular channel adjacent the bait tube wall in the hot zone, thereby increasing deposition rate and efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE                    A system for providing a buffer between upstream and downstream article processing lines employs a storage and retriev-al machine operable in a storage mode to store in a matrix of storage bins unit loads of articles received from the upstream line during an interruption in the processing rate of the down-stream line; and, operable in a retrieval mode to supply the stor-ed articles to the downstream line when required. The storage machine includes separately driven components consisting of a horizontally movable carriage, a vertically movable elevator mounted on the carriage, and a bi-laterally movable load carrying table mounted on the elevator.  Movements of these components are regulated by a control which counts the number of unit loads in storage and computes, in accordance with predetermined storage and retrieval sequences, the location in the matrix of the storage bin for the next storage or retrieval operation and directs the machine table to that location.  In the storage mode, each suc-cessive storage operation of the machine is initiated in response to the presence of a group of articles, or unit load, at a trans-fer station located adjacent the entrance to the downstream line; and, in the retrieval mode, each successive operation of the machine occurs in response to the deposit of a unit load on the transfer station by the table of the machine.

Abstract: ABSTRACT OF THE DISCLOSURE          There are disclosed a flexible printed circuit base board produced as an elemental material suitable for a flexible printed circuit board by coating a heat-resistant resin composition composed of a heat-resistant resin having a heterocyclic ring and an epoxy resin dissolved in an organic solvent on a metal foil and drying it to form a film directly on said foil, and a method for producing the same.  Said flexible printed circuit base board is more excellent in heat resistance, flame retardancy, adhesiveness, electric insulation, and heat deterioration characteristics than the conven-tional base board obtained by integrating a heat-resistant film and a metal foil through an adhesive.  These properties are of great importance in practical applications of the printed circuit base board.  As compared with the conven-tional products, the production is easy, and hence, the present base board can be produced at a low cost.  The base board of this invention is not only usable for various types of flexible printed circuit boards but also the film per se obtained from the base board can be used in a field in which a film is used.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a novel heat recouperator for returning an incident beam of radiative energy to its source, the beam being incident from any direction within a predetermined solid angle.  The recouperator comprises a main array of radiant heat reflecting cells, each comprising a substrate defining at least three planar surfaces intersecting each other in angles of approximately 90°, each of the planar surfaces being in the form of a geometric figure having at least four edges, front substrate surfaces facing the solid angle being reflective of a major fraction of incident electro-magnetic radiation in the wavelength band of about 1 micron to about 20 microns, the incident beam of radiation has direction cosines (a,b,c) in the coordinate system oriented with the intersections of the planar surfaces.  The recouperator further includes at least one secondary array of the reflecting cells, the secondary array positioned with respect to the main array at a direction defined by a set of direction cosines chosen from the following group:        -a, b, c;        -a, -b, c; a, -b, c; a, -b, -c; a, b, -c;        -a, b, -c.  The recouperator is particularly useful for the recovery of heat and is most effective in returning radiant energy which is emitted from a source back to the source.  The device is relatively inexpensive to manufacture and easy to install and maintain.

Abstract: RCA 72,659 Abstract of the Disclosure In a color television receiver including a comb filter for separating luminance and chrominance components of a color television signal, a network is included for selectively restoring, enhancing and paring vertical image detail to preserve and enhance vertical resolution in the luminance content of a displayed image.  The comb filter provides a combed luminance signal output from which vertical detail signal information has been unavoidably deleted, and a combed chrominance signal output including signal frequency components representative of the deleted detail signal, which are selectively extracted from the combed chrominance signal. Low level detail signals are restored to the combed luminance signal via a first signal processing network which exhibits a prescribed signal restoration gain.  The detail signal is also combined with the combed luminance signal via a second signal processing network which cores (removes) low level detail signals including noise, enhances moderate level detail signals through amplification to enhance vertical image definition, and pares (amplitude reduces) high level detail signals.  A resultant reconstituted luminance component manifests restored low level vertical detail information, enhanced moderate level vertical detail information without enhancing unwanted signal components such as noise, and pared high level detail signals to avoid excessive contrast.
