Abstract: REVERSIBLE COLOR DECK FOR ROTARY PRINTING PRESSES              Abstract of the Disclosure A  reversible  color  deck  apparatus  for  rotary printing presses for permitting a printer to selectively print a plurality of colors on one side or the other of a paper web.  The apparatus includes a plurality of image delivery rolls or cylinders disposed in spaced relation. A pair of blanket rolls or cylinders are disposed within the space separating the image delivery rolls and are supported  at  their  ends  by  eccentric  sleeve  elements. These sleeve elements are operatively interconnected by control  linkage  which,  in  turn,  is  connected  to  an actuating member for effecting simultaneous movement of the axes of rotation of the blanket rolls in the same directions.   Via a  neutral  or  throw off position,  the axes of rotation of the blanket rolls can be moved to two different  positions  which  permit  the  printing  of  a plurality of colors on that side of the web corresponding to the particular position to which the blanket rolls were selected to be moved.

Abstract: ABSTRACT   The invention is concerned with an electro-chemical gas analyzer for determining the sulphur dioxide content of certain gases, in particular, flue gases.  The device comprises a measuring cell containing a measuring electrode for the determination of the depolarization current and further comprising an unpolarizable electrode in the same electrolyte.  The gas input flow is utilized to cause a circulation of electrolyte containing the diss-olved gas which moves in the space between the measuring and counter-electrode. The electrolyte is continuously renewed and the electrolyte leaving the cell is regenerated and recycled.  The sulphur dioxide dissolved in the electrolyte is removed outside the cell by treatment with air in the presence of activated charcoal.

Abstract: Abstract of the Disclosure An alumina-carbon shape is manufactured from a com-position comprising 1 - 8 weight percent fine silicon, 1 -16 weight percent reactive alumina, 1 - 30 weight percent calcined fluidized bed coke, 1 - 30 weight percent of a spalling inhibiting additive, and the balance of the mix synthetic alumina, plus the additions of 5 - 10 weight per-cent of a high carbon yielding resin as a molding vehicle and 0.5 - 4 weight percent solvent, and up to 2 weight per-cent of a low temperature curing agent, such as, paraformal-dehyde or hydrochloric acid.  The mix is formed at ambient temperature into a shape through an injection molding pro-cess.  Solidification is accomplished by curing in the mold at a temperature less than 100°C.  After stripping the shape from the mold, the solvents are removed from the shape by drying at a temperature above 100°C.  The shapes are then heated to a temperature above 550°C to coke the resin.  The shapes may be tar impregnated to decrease coked porosity and to increase their resistance to mold powder.

Abstract: Abstract of the Disclosure A circuit arrangement is disclosed for providing in a fail-safe manner an alternating output signal to a load, e.g. in a railway signaling system.  The load is connected across a first winding of a transformer, to opposite ends of a second winding of which transformer is connected a bi-directional current switching circuit.  First and second modulated signal sources are connected to the bi-directional switching circuit. Each of the signal sources modulates a carrier signal with a modulation signal, to outputs of the signal sources being in anti-phase with respect to each other. The bi-directional switching circuit is operative to switch current through the second winding alternately in opposite directions at the frequency of the modulation signal.  The circuit arrangement is such that if any of its components fails to operate correctly, the output appearing across the first winding is no greater than a threshold level.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for forming deep drawn highly oriented thin-walled thermoplastic articles including the steps of planarly supporting a sheet of at least partially crystalline thermoplastic polymeric material and establishing at least one differentially heated area within the sheet. The differentially heated area is to include an outer cool zone having a temperature range generally below the crystalline melt point of the thermoplastic material, a hot zone disposed within the outer zone having a temperature range generally above the crystalline melt point but below the complete melt point of the thermoplastic material, and an inner cool zone located centrally of the hot zone having a temperature range generally below the crystalline melt point of the thermoplastic material. The heated sheet is placed between a female mold unit and a forming mandrel with the inner cool zone generally axially aligned therewith. The mandrel is driven against the inner cool zone of the heated sheet and into the female mold unit so that the thermoplastic material is drawn radially inwardly toward the inner cool zone and around the mandrel forming an elongated generally cylindrical shaped preform having a central cavity. The material is longitudinally stretched a distance sufficient to cause at least a portion of the walls of the preform to undergo strain hardening while the outer cool zone maintains tension control of the sheet material throughout the forming process. The central cavity of the elongated preform is then subjected to internal fluid pressure to radially expand the preform against the interior surface of the female mold cavity. The fluid pressure is maintained for a time sufficient to allow the expanded material to cool and set.
