Abstract: Abstract of the Disclosure This invention discloses a process for coating a reproduction layer onto one or both sides of 2 metal support material.   The process is carried out in two steps: a) The surface of the metal support is electrochemically treated in an aqueous electrolyte to produce a hydrophilic intermediate layer, b) the hydrophilized surface is coated with a photosensitive layer in an electrophoretic process.          In step a), the aqueous electrolyte contains at least one water-soluble compound selected from the group consisting of sulfonic, phosphonic and at least tribasic carboxylic acids, phosphoric acid esters which still have at least one acid functional group and alkali metal salts and ammonium salts of said acids or esters (e.g. polyvinyl phosphonic acid or phytic acid).  In step b), the aqueous electro-lyte contains at least one photosensitive compound which is soluble or dispersible in water (e.g. a diazonium-salt polycondensate) and optionally a binder which is soluble or dispersible in water.      A material which has been coated according to the process of the invention is preferably used as a litho-graphic printing plate.

Abstract: ENCLOSURE FOR ELECTRICAL AND ELECTRONIC EQUIPMENT, WITH TEMPERATURE EQUALIZATION AND CONTROL         Abstract of the Disclosure An enclosure for electrical equipment is arranged in sections, typically vertical and with an equipment mounting section at the front and an air passage section at the rear.  Air is constantly circulated through the two sections, in a closed loop, to maintain an even temperature and avoid hotspots in the enclosure.  At the top, one or more fans are positioned over each section, and an air inlet and an air outlet are provided.  A pivotal baffle has two positions.  In one it shuts off access to the inlet and outlet and permits the closed circulation of air. In the other position it shuts off circulation between sections at one end and opens access to the inlet and outlet, giving an air circulation from the inlet, through the sections and out of the outlet.  An additional fan can be switched on for the latter form of circulation.

Abstract: PHN 10378                22                       7.10.82 ABSTRACT: Large-excursion electroacoustic transducer.     An electroacoustic transducer comprises a dia-phragm (1), a magnet system (4) and a voice coil (3) ar-ranged on a voice-coil former (2) in an air gap (5) of the magnet system (4). The movement is transmitted be-tween the voice-coil former (2) and the diaphragm (1) via a lever mechanism. The lever mechanism comprises n lever devices (such as 6) which are arranged at an angle relative to each other (n ? 2). A lever device (6) com-prises a lever arm (9) which is coupled to a fulcrum (11) at the location of a first position (10) on the lever arm, to the voice-coil former (2) at the location of a se-cond position (13), and to the diaphragm (1) at the loca-tion of a third position (14). The lever mechanism mul-tiplies the excursion of the voice-coil former by a fac-tor, which factor is suitably greater than unity. This results in an electroacoustic transducer with a long stroke (in which large excursions of the diaphragm are possible). The lever mechanism by means of which a larger excursion is obtained may also be employed in other types of transducer, such as piezo-ceramic transducers. Suit-ably, the compliant element (25) formed by a zigzag bel-lows secured both to the outer circumference of the dia-phragm (1) and to the chassis (26) of the transducer and permitting the large excursion of the diaphragm, is con-structed so as to reduce the acoustic contribution of the compliant element to the output signal of the transducer, which contribution forms a distortion component in the output signal.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method of manufacturing solid metallic materials having a circular cross section by employing a rotary mill.  A three or four roll cross-type rotary mill is employed, with cross and feed angle setting selected so as to meet specific conditions. The method permits efficient production of metallic materials without internal cracks or internal fracture initiated from porosity.  In one version of the method the material being worked is rotated.  In another ver-sion the material is not rotated and the roll housing is rotated around the former.  Where the latter version is employed, it is possible to work the material as produced by a continuous casting machine and without cutting.

Abstract: ABSTRACT OF THE DISCLOSURE      A  demountable   partitioning   system  comprises multi-purpose aluminium extrusions adapted to be snap-fitted together in a number of different configurations to suit different constructional and system design re-quirements.   The system centres around two universal sections (FW1,FW11) each in the form of a rectangular channel open at one side and provided with formations (3,4,5)  enabling  other  extrusions  selected  from  a glazing  infill  section  (FW3),  a  blank  end section (FW4), and a door infill section (FW5) each provided with complementary formations (8,10) to be snap-fitted onto  one  or  more  sides  of  the  universal  section (FW1,FW11).   Extruded aluminium or  plastics  glazing channels  (FW6,FW7,FW8)  capable  of  engaging  with  a number of  different glazing beads  (FG) can be snap-fitted with the universal sections (FW1,FW11) and with the  glazing  infill  (FW3)  for  assembling  single  or double glazing as desired  to  the universal  sections (FW1)FW11).  The universal sections (FW1,FW11) also can engage with wall panels of a partitioning installation.          Fixing clips (FS1,FS2,FS3 and FS4) are disclosed which enable gapless panel joints to be made, and the system further   includes   corner   and   reducing   sections (FW9,FW10)     and     wiring     ducting     sections (FW13,FW14,FW15).  The system is cost advantageous, can be  installed quickly and  is  readily demountable and reusable, and requires a minimum of secondary fixings (screws, bolts, etc.).

Abstract: ABSTRACT OF THE DISCLOSURE           A random multi-error correcting code having a maximum length block in a packet, for instance, a majority logic decodable (272, 190) shortened difference set cyclic code is used for the error correction in a character code broadcasting system.  The error correcting ability of this code is increased.  If errors cannot be corrected, the leading bit is shifted, so that more than 8-bit errors is to be corrected.  Also, the correction is made by decreasing the threshold value, so that the error correcting ability is improved.  Framing timing extraction circuit and a phase lock circuit for the framing timing are eliminated, so that a load of the hardware is reduced.          Preferably, the error correcting code is superposed on the television signal during a vertical blanking period.

Abstract: ABSTRACT OF THE DISCLOSURE          "METHOD OF SEISMIC COLLECTION UTILIZING MULTICOMPONENT RECEIVERS          FOLLOWED BY TIME DOMAIN MIGRATION OF AT LEAST TWO SETS OF RESULTING          ELASTIC WAVE FIELDS UTILIZING WAVE TRACKING OF THE FIELDS          FOLLOWED BY COMPOSITE IMAGING"         By using wave tracking rather than a downward continuation concept, two sets of elastic wave fields (one generated by a seismic source, the other recorded by mul-ticomponent geophones) are migrated separately and are then imaged.  The process is repeated for common shot gathers, and then the images (associated with each common midpoint gathers), are stacked.         As a consequence of wave tracking, migration operations are preferably performed in the time domain using finite difference discretization equations involving vector properties of the fields but without having to reduce the latter to one-way wave equations.  Result: the method of the present invention (i)  easily handles reflectors of arbitrary dip angle;     (ii)  handles interspatial elastic conversions;     (iii)  eliminates multiples generated by known velo-city contrasts;     (iv)  takes account of different field source-receiver geometries:     (v)  provides higher signal-to-noise ratio character-istics since a larger portion of wave energy is migrated than in conventional migration methods of which I am aware; and (vi)  has a symbiotic relationship when used with modern vector-based computing systems such as the Cray I, Cray Corporation, Cupertino, California, based on the fact that since the fields themselves are defined by vector properties, operations are surprisingly sped.
