Patent GB-1334858-A (GB)
Title: Cassette
IPC: B65H75/16
Filed: 1970-11-05
Abstract: 1334858 Xerographic cassettes XEROX CORP 5 Nov 1970 [7. Nov 1969] 52679/70 Heading G2A A cassette comprises a base member 42 and a cover 44 connected together at a hinge 46, the base member having a centrally raised support surface 56 at each side of which are guide channels 56, 60; beyond the channels are support rails so shaped that they will locate a plate initially placed on the support surface 56, and also support that plate when the cassette is inverted. The cassette is intended for xerographic X-ray plates, in an automated processing system in which the plates are introduced into the cassette and withdrawn therefrom automatically. As shown, the channels at either side of the centrally raised surface 56 comprise two channels 58, 60, separated by a ridge 62. These ridges co-operate with side rails on the xerographic plate, so that the plate can be guided into position. Beyond the channels 58, 60 are L-shaped support rails 64, which guide the plate into position as it is automatically inserted into the cassette. After such insertion the cassette is usually inverted for entry into the printing unit. In such inverted position the plate is supported by the rails 64 without contacting the photo-conductive layer. The cover and base member have a tongue and groove construction so that they fit together to form a light-tight enclosure. Latch members (94), Fig.1 (not shown) are provided, with notches 92 in front of them through which fingers on cassette-opening means forming part of the automated mechanism can enter to actuate the latches. A membrane (127), Fig.5 (not shown) such as cloth or plastic film can be mounted on the cover so as to lie in parallel closely spaced relationship to the photo-conductive layer to prevent ionic degradation thereof during radiographic imaging. Holes may be provided for the escape of air trapped between the membrane and the cover. A filter (138) may be provided in the cover for modifying the radiation entering the cassette.

Title: Improvements in or relating to the regeneration of absorbent liquor containing dissolved acidic gases
Inventor: THIRKELL HARRY
IPC: C10K1/12
Filed: 1965-12-31
Abstract: Absorbent liquor containing dissolved acidic gases, e.g CO2, H2S, is regenerated by stripping with steam; the liquor is then passed into a reboiler (18) and evolves steam which is used for stripping; the heating medium in reboiler (18) is steam which is thereby condensed and passed to another reboiler (10) where it is heated by a hot fluid and evolves steam which is recycled to reboiler (18).  The fluid used in (10) may be passed, optionally with additional hot fluid, into a third reboiler (33) to heat another portion of regenerated liquor which also evolves steam, and the steam is recycled for stripping. The fluid may be the gases leaving the CO conversion step after partial oxidation or steam reformation of hydrocarbons, which are subsequently scrubbed with the regenerated liquor.  The acidic gases from the regenerator (2) pass to air cooler (25) and the mixture of cooled gases and condensed steam is separated (at 27), the latter being returned to the top of the regenerator.  Unevaporated liquor from reboilers 18 and 33 is returned to the bottom of the regenerator. Weirs are provided in the reboilers to ensure the liquid covers the heating tubes.  The absorbent liquor may be aqueous monoethanolamine or K2CO3.ALSO:Absorbent liquor containing dissolved acidic gases, e.g CO2, H2S, is regenerated by stripping with steam; the liquor is then passed into a reboiler (18) and evolves steam which is used for stripping; the heating medium in reboiler (18) is steam which is thereby condensed and passed to another reboiler (10) where it is heated by a hot fluid and evolves steam which is recycled to reboiler (18).
