Abstract: METHOD OF CONTROLLING CHEMICAL AND/OR PHYSICAL   REACTIONS IN THE ATMOSPHERE            Abstract of the Disclosure The invention relates to a method for local and wide-area controlling of chemical and/or physical reactions in the atmosphere.  For instance, sulphur dioxide contained in flue gases is known to be the source of the problems associated with "acid rain" and with the "dry fallout".  An effective tackling of these problems has been as little successful as that of resolving the problem of smog formation.      Flue gas desulfurizing devices altogether produce a very low result which is disproportionate to the cost.  These and other problems can be solved according to the invention such that by a system comprised of smokestacks or other building structures producing the updraft effect, which is known per se, and by using thermal and kinetic flows in the atmosphere, active substances are introduced into the atmosphere in such a volume and spatial distribution that the active substances produce the respective desired control in reacting with the components already contained in the atmosphere.  The active substances can be adjusted to the respective desired purpose and can be systematically introduced into the atmosphere such that an effective protection is also possible over large regions.

Abstract: DISSOLUTION OF METALS UTILIZING A FURAN DERIVATIVE                          ABSTRACT         Improved metal dissolution rates are obtained when using a solution containing sulfuric acid, hydrogen peroxide and a cata-lytic amount of a furan derivative such as tetrahydrofurfuryl alcohol or tetrahydrofuran.         The present invention relates to the dissolution of metals in an aqueous bath containing sulfuric acid and hydrogen peroxide, and in particular to a novel bath composition capable of effecting the dissolution at high rates.  In one specific aspect the invention is concerned with etching of copper in the production of printed circuit boards.                 BACKGROUND OF THE INVENTION           As is well known in the art, in the manufacture of printed electronic circuits a laminate of copper and etch resistant material, usually plastic, is used.  A common method of obtaining the circuits is to mask the desired pattern on the copper surface of the laminate with a protective resist material, which is imper-vious to the action of an etch solution.  In a subsequent etching step, the unprotected areas of the copper are etched away, while the masked areas remain intact and provide the desired circuiting supported by the plastic.  The resist material can be a plastic material, an ink or a solder.           In the last few years, the industry has more and more turned to hydrogen peroxide-sulfuric acid systems for etching the electronic circuit boards, due to the low cost of the etching solu-tions and to the relative ease with which copper values can be recovered from the spent etch solutions.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for producing an aromatic polyketone which comprises polymerizing an appropriate monomer or monomers by a Friedel-Crafts polymerization reaction using a Lewis acid catalyst.  A controlling agent such as a Lewis base may be added to the reaction medium and/or the reaction is conducted under specified conditions to control the reaction.  The reaction medium comprises, for example, aluminum trichloride as the Lewis acid, an organic Lewis base such as N,N-dimethylformamide or an inorganic Lewis base such as sodium or lithium chloride, and a diluent such as methylene chloride or dichloroethane.  The amount of Lewis acid, the amount of Lewis base, the temperature of the reaction and the monomer to diluent ratio are varied depending on the monomer system to obtain melt-processable, high molecular weight, substantially linear polymers, for example poly (carbonyl-p-phenylene-p-oxy-p-phenylene), poly(carbonyl-p-phenylene-p-oxy-p-phenylene-p-oxy-p-phenylene), and the like.          Copolymers containing up to 30% by weight of an aromatic sulfonyl halide comonomer can also advantageously be produced by this process.

Abstract: ABSTRACT         A machine for manufacturing a unitary glass fibre reinforced body shell includes a carriage which is movable along the mold and a turntable which is mounted on a carriage for rotation about a first axis extending in the direction of longitudinal movement of the carriage.  An arm is slidably mounted on the turntable for radial movement and a dispenser is located on the arm for dispensing glass fibre reinforced resin onto the surface of the mold.  A guidance system is provided which interconnects the turret and the slidable arm and is operable to cause the arm to reciprocate with respect to the turret in a radial direction to maintain a substantially constant length of trajectory extending between the dispenser and the wall of the mold.  A drive system is provided for rotatably driving the turret about the axis.  The carriage is normally stored on a mobile end cap which may be moved from one mold to another and serves to close one end of the mold.  A canopy is mounted with one end connected to the mold and the other end connected to the dispenser carriage such that as the dispenser carriage moves along the mold, the canopy is deployed to cover the open upper end of the mold to form an enclosed chamber from which fumes may be extracted.         The method of forming the required body shell includes the steps of dispensing a coating of glass fibre reinforced resin onto the forming surface of a mold while moving the dispenser along successive longitudinally displaced U-shaped paths which traverse the forming surface to form a continuous coating covering the top and side forming walls of the mold cavity.  The further step of compacting the coating by applying a compactor to the inner surface of the coating and moving the compactor along the same path as that followed by the dispenser at a point located downstream from the dispenser.

Abstract: ABSTRACT OF THE DISCLOSURE    A safety mounting device includes two movable members mounted within a housing, the second movable member being sandwiched between the first movable member and a stop member and the first movable member being biased against the second movable member.  Both movable members are movable along the longitudinal axis of the housing with the second movable member also being capable of tilting with respect to that longitudinal axis and rotating with respect to that longitudinal axis.  The engagement between the two movable members is of a cam surface-cam follower nature.  Movement of the second movable member along the longitudinal axis towards the first movable member, rotation of the second movable member from its home position and tilting of the second movable member relative to the longitudinal axis all cause the first movable member to be displaced from its home position along the longitudinal axis.  This displacement can be used to trigger a switch for control purposes.
