Title: Press device
IPC: B21D28/10
Filed: 1973-01-01
Abstract: 1416471 Punching E M DUBOIS 1 Jan 1973 [7 March 1972] 117/73 Heading B4B [Also in Divisions B3 and B6] The reciprocating tool spindle 26 of a portable C frame press is located in a selected one of a plurality of rotational positions by a spring- loaded pin 33 which is readily releasable to allow rotation of the spindle. The bending cutter 30 shown co-operates with die blocks 21, 22 to louvres 39 in a metal or plastics strip, a resilient pad 29 clamping the strip to the die block 22 to form a sharp demarcation between the plane and bent portions of the strip. Keyways 31, 32 for the pin 33 are spaced by 90 degrees about the circumference of the spindle and a die support 19 is rotatable about an arbor 20 to bring pin 16 or 17, similarly angularly spaced on the C frame, into register with a hole 24 in the die support. The spacing of the die blocks 21 and 22 on the support is variable to suit the width of louvres to be formed. The width of interchangeable block 22 is equal to one width of the plane portions between the louvres so that the block acts as a ganging stop against which, before each shearing stroke, the just-formed louvre can be located. A metal or plastics spacer (40) Fig. 6 (not shown) may be needed with plastics strip to keep the louvre 39 at the desired angle. The spindle is reciprocated by a lever (37), Fig. 1 (not shown), through a cam (14) pivoted in a bracket (12) on the frame. Other operations for which the press is suitable are punching, perforating, bending and shaping.

Title: A process for the thermal decomposition of waste sulphuric acid
Inventor: HAESELER HARKE
IPC: C01B17/58
Filed: 1965-01-01
Abstract: SO2 is formed by the thermal decomposition of waste sulphuric acid with the stoichiometric amount of carbonaceous fuel and at least the stoichiometric amount of a free oxygen-containing gas under high turbulence at 650-1000 DEG C., such that the residence time for reactants and products in the combustion zone is less than 1 second. The carbonaceous fuel, e.g. oil, illuminating gas, water gas, lignite dust or organic impurities in the acid, may be mixed with H2SO4 prior to the reaction zone.  Liquid sulphur may be used with the carbonaceous fuel, and may be injected in the opposite direction to the acid which may have previously been mixed with the carbonaceous fuel.  The waste acid may contain 20-96% H2SO4.  An apparatus is described in which the heated acid and carbonaceous fuel are passed through a mixing valve and injected into the combustion chamber with heated air, in opposition to a charge of liquid sulphur if used, and then through heat-exchangers into an electrostatic dust separator to remove inorganic impurities.
