Title: Suction hood with metal filter - for vapour removal e.g. from cookers
IPC: B08B15/02
Filed: 1974-04-11
Abstract: Vapour suction hood with edge suction of the known type comprises a housing open at the lower edge which is partly closed off by a bottom wall, the edges of which extend nearly up to the walls of the housing, so that a suction slit results between these edges and the walls running round the whole periphery of the bottom wall. This wall is hinged and gives access to a metal filter. A discharge channel is formed in the housing, one end of which opens out onto one wall of the housing and the other extends to some distance above the lower wall. A fan is installed in the channel and a filter mounted in front of the end of the channel opening opposite the lower wall. The installed filter is easily cleaned and is non-inflammable, in contrast to textile fibre felt filters.

Abstract: COMMON CONTROL FRAMING DETECTOR          Abstract of the Disclosure The PCM encoded digital data groups transmitted to a switching office are respectively stored a frame at a time and then read out from store in a sequence such that a plurality of digital groups are multiplexed on to a common bus.  A common control framing detector continually monitors, at the multiplex point, all of the digital groups on a time multi-plexed basis.  The framing pattern status of each group is stored in a shared recirculating memory, which is continually updated in accordance with changes introduced into each group signal by the switching office for synchronization and reframing purposes.  The stored framing pattern status of each digital group is compared with the group framing bits as each group appears on the multiplexed bus.  If the comparison fails, an error signal is generated.  An error timing store counts the error signal for each group and when the error count of a given group reaches a predetermined threshold an out-of-frame signal is generated which initiates a reframe operation for the out-of-frame group.

Advantageously, about 50% of the total quantity of sulphuric acid used is introduced into the washing circuits of each of the two preliminary sulphuric acid washers, and the water content in the washing circuits is adjusted by regulating the pro-portion introduced into the first H2SO4 washing circuit of the quantity of oleum required for adjusting the charging acid.  The rate of acid addition and concentration are substantially constant but may be periodically adjusted to keep the water contents in the washing stages at the desired levels.

Abstract: ABSTRACT OF THE DISCLOSURE          The processing of gas streams containing hydrocarbons and other gases of similar volatility to recover high yields of components such as ethane, propane, and heavier hydrocarbons therefrom by cooling said gas stream under pressure to form a liquid portion, and expanding the liquid portion to a pressure lower than feed pressure whereby a part of the liquid portion vaporizes to cool the remaining part of the liquid portion is improved by pre-cooling the liquid portion prior to flash ex-pansion.  In one embodiment this is accomplished by dividing the remaining part of the liquid portion into a first and second stream, directing the first liquid stream into heat exchange relation with the liquid portion of the feed stream prior to expansion to warm the first liquid stream and pre-cool the liquid portion prior to expansion.  Both first and second liquid streams are then supplied to a fractionating column, the second stream being supplied to the fractionating column at a point thereon higher than the first stream.  Several other methods of pre-cooling the liquid portion are also described.
