Abstract: ABSTRACT OF THE DISCLOSURE            A method and an apparatus for the manufacture of heat--exchanger rolls. The roll consists of two webs of material which are wound together in superposed relationship. One of the webs is corrugated and formed with protrusions/dents at the crests and bottoms of the corrugations. The second web is provided with lengthwise ribs having the same configuration as the protrusions/dents. When the webs are wound into a roll a radial pressure is exerted on the wheel in order to press the ribs efficiently into the protrusions/dents and to achieve efficient and safe interconnection of the various winding turns making up the roll. To impart a tension in said webs a retarding (braking) force is applied thereon during the winding-on of the webs.          The invention also comprises an apparatus for performing the method, the pressure and braking force on said webs being exerted by a pressure roller.

Abstract: ABSTRACT      A bandpass filter has a plurality of cascade waveguide cavities each resonating in three independent orthogonal modes.  The cavities can be cylindrical or have a square cross-section.  Where the cavities are circular, each cavity resonates in TE111 and TM010 modes simultaneously.  Where the cavities have a square cross-section, each cavity resonates in TE101 and TM110 modes simultaneously.  Between each triple-mode cavity, there is located an iris having an aperture with four separate radial slots that are offset from a centre of the iris.  The filter is capable of producing an elliptic function response.  In a variation of the invention, an allpass filter has an output that is short circuited and, when used in conjunction with a circulator, it functions as a group delay equalizer.          Previous triple-mode filters are not capable of pro-ducing an acceptable result relative to dual-mode filters.  By utilizing a bandpass filter in accordance with the present invention, a weight and volume saving can be achieved over comparable dual-mode bandpass filters.  Previous dual-mode allpass networks are not capable of producing equal response characteristics as triple-mode allpass networks in accordance with the present invention.

Abstract: CALENDER SELF-LOCKING LOADING MECHANISM               ABSTRACT OF THE DISCLOSURE           An improved pressure actuator particularly suited to loading of rolls in the calender stack is disclosed.  The actuator is formed by a pair of spaced arms interconnected by a link.  A pressure absorbing locking bar is interposed between a pair of adjacent ends of the arm and a pressure actuator is interposed between the arms of the opposite side of the link.          The link itself is pivoted to the frame so that movement of the link around its pivot point on the frame causes the arms to move so that one arm moves into an active position and the other into a reactive or pressure applying position and vice versa.  In the reactive position, a locking member on a pressure plate that engages the locking bar locks the arm in reactive position in position so that pressure applied by the actuator between the opposite ends forces the other arm to pivot around its pivotal connection to the link, thereby applying pressure to a load in one direction.

Abstract: ABSTRACT Disclosed is a novel machine readable document and process wherein variable data, once located on a document and classified as to type, may be accurately read and digitized notwithstanding the presence of background patterns or pictures of an unlimited and unknown variety. The document may be a check with the maker's signature in a first horizontal band area.  The written pages and numerical amount appear within second and third band areas on the check.  Fluorescent or phosphorescent ink is applied as background on the band areas and trips a scanner when subjected to ultraviolet light. Once tripped, the scanner reads only preselected portions of the check, namely the band areas.  Any writing within the areas and on top of the ink sharply contrasts with the background ink to permit the handwritten matter within the band areas to develop information signals corresponding only to the hand-written portion of the check.  Data at an unknown location on various documents, including checks, may be machine located, read, digitized and compiled into a summary or composite statement.

Abstract: ABSTRACT            In an eddy-current brake (10) for controlling quantita-tive flow in a waterline and with a brake housing (11) in the shape of a lying frustum of a cone with an outlet opening (14) in the narrow end and an inlet opening (13) downwardly on the large end face (12) there is disposed a guide vane (24) opposite the inlet opening within the housing, said guide vane (24) being rotatable about the axis of the housing by means of an exterior adjustment lever (21) between  a position in which it closes the inlet, and a position in which it is disposed completely outside the inlet region and thus allows free flow. In intermediate positions the guide vane deflects the inflowing stream of water toward the frusto-conical wall so that the water, when the pressure head exceeds a certain value, is caused to rotate about the axis of the housing to produce the desired brake effect.          This effect can by varied by adjustment of the guide vane. Its deflecting effect permits the inlet spout (15) and outlet spout (16) of the brake housing to be disposed in elongation of each other, which involves great advantages in terms of incorporation.     Fig. 1 should be published.

Abstract: FIBER OPTIC AMPLIFIER                Abstract of the Invention An  amplifier  for  use  with  fiber  optic  systems comprises a neodymium YAG crystal placed in series with a signal-carrying  optical  fiber. The ND;YAG  crystal  is supplied by the optical fiber with both the signal to be amplified,   and  pumping  illumination.     The  pumping illumination  is  coupled  onto  the  optical  fiber  by  a multiplexing coupler which is used to combine the signal to  be  amplified   and   illumination  from  a  pumping illumination source onto the single optical fiber.   The pumping illumination inverts the neodymium ions within the ND:YAG crystal.   The signal to be amplified propagates through this  crystal  to  stimulate  emission of coherent light from the neodymium ions, resulting in amplification of  the  signal.    Because this  arrangement  permits  the ND;YAG crystal to be end-pumped with pumping illumination, and  because  the  length  of  the ND:YAG  crystal may be substantially greater than the absorption length for the crystal at the wavelength of the pumping illumination, virtually all of the pumping illumination may be absorbed within the ND:YAG crystal and used for amplification of the signal carried by the optical fiber.

Abstract: ABSTRACT            The invention relates to a process for manufacturing highly active, dispersed aluminum hydroxide, of low apparent den-sity                        .  First,  unground,  very  fine grained aluminum tri-hydroxide, of which more than 99 % of the grains are at most 3 µm in size, is introduced conti-nuously into a reactor along with a stream of hot dry air, is whirled up and strongly dispersed, heated to 400-600°C and  shock dehydrated.  The  low apparent density aluminum oxide flowing out of the reactor in the hot air stream is precipitated out by suitable mechanical means, dispersed in mildly acidic or mildly basic water and rehydrated with the aid of heating.          The invention also relates to shaped components of highly active, dispersed low apparent density aluminum oxide ha-ving a specific surface area of at least 200 m2/g, a pore volume of more than 1.2 cm3/g and adequate resistance to fracture and wear.          The shaped components are in particular produced by trea-ting low apparent density aluminum oxide with rehydrated grains and extruding as a pliable mass, or by rolling the low apparent density aluminum oxide grains in a cumulative granulation process in which water is added during granu-lation.
