Patent EP-0103779-A3 (EP)
IPC: C09K8/42
Filed: 1983-08-26
Abstract: An improved process for removing solid contaminates 
from a high density, salt-type aqueous drilling/completion 
packer fluid prior to its introduction into the well bore and for 
removing contaminates such as drilling mud and fluids from 
the well system prior to the introduction of brine to maintain 
the brine in a solids free state. To remove the solid 
contaminants, small effective amount of an alcohol and a 
suractant are added to the brine. After the solid contamin­
ates agglomerate, the solids are separated, leaving the brine 
in a substantially solids-free state.  
     To remove the contaminates from the well system, 
treated water is prepared with a surfactant and alcohol 
admixed in clean water. Without interrupting circulation, the 
treated water displaces the fluids and drilling mud within the 
well system. Circulation of the treated water continues until 
substantially all of the contaminates are carried in the 
circulated treated water. The treated water may be preceded 
or followed by another fluid which assists in removing the 
contaminates. The solids-free brine is introduced into the 
well system to displace the treated water without exposure 
to the contaminates.

IPC: B01D53/86
Filed: 1984-06-14
Abstract: A catalyst device for purifying a carbon monoxide con­
taining atmosphere, e.g. for use in breathing apparatus for 
underground workers, comprises a chamber containing a 
catalyst bed for low temperature oxidation of carbon monox­
ide and having an inlet for permitting ingress of air from the 
atmosphere and an exit for connection to the face of the user, 
e.g. by means of a face mask. When the mask (for example) 
and the chamber are in pneumatic connection, inhalation 
through the mask causes air to enter the chamber via the inlet, 
to contact the catalyst bed for catalytic oxidation of CO therin, 
if present, and thence pass to the mask.  
     In order to provide resistance to deactivation by water 
vapour and obviate the need for a drying agent, the catalyst 
bed comprises one or more platinum group metals in combi­
nation with tin (IV) oxide e.g. Pt and Pd in combination with tin 
(IV) oxide.

IPC: H03M7/50
Filed: 1986-08-08
Abstract: A linear to A-law (3) and A-law to linear pcm-tdm (4) 
encoding circuit converts two sixteen bit linear encoded 
pcm-tdm data streams (LXA,LXB) to one eight bit A-law encoded 
pcm-tdm data stream (AX) having twice as many channels and 
vice-versa (AR,LRA,LRB). Incoming bit streams constantly step through 
the circuit with either A-law encoded or linear encoded 
data being converted to an intermediate code comprising a 
sign bit, a chord number and step bits prior to conversion 
to the desired output encoding. Using shift registers and 
multiplexers addressed by stored chord numbers ensures 
minimum delay of the data during conversion.
