Patent EP-0153125-A3 (EP)
IPC: H04W84/02
Filed: 1985-02-12
Abstract: Tone detection apparatus for use in a voice message an­
swering system operates to provide for dual tone multi-fre­
quency (DTMF) tone detection where an outgoing analog voice 
signal is connected to a telephone line (12). When an incoming 
call is detected, the tone detector (42) looks at the incoming 
analog signal and if a dual tone control signal is detected, a filter 
(22, 50) is switched to filter the outgoing analog signal so that 
the DTMF tone signal now being detected is filtered out of the 
outgoing signal. If the incoming signal still detects a tone, the 
tone detector (42) cuts off or disconnects the outgoing signal 
completely for approximately 20 milliseconds. If a dual tone 
control signal is still detected, it is determined that it is an in­
coming control signal and consequently access is required into 
the voice message system.

Title: A method of manufacturing bleached chemimechanical and semichemical fibre pulp by means of a two-stage impregnation process
IPC: D21B1/14
Filed: 1986-03-07
Abstract: Chemimechanical pulp is produced from lignocellulosic material in a process in which the material is impregnated in two stages.

The quantities of alkali and peroxide charged are fully optional and are independent of one another. The material is then optionally subjected to a further drainage and reaction step, and thereafter pre-heated at a temperature of between 50°C and 100°C, whereafter the material is refined in one or two stages.The optimal brightness of the processed pulp for a given peroxide consumption is achieved by a balanced division of the peroxide charge between chip impregnation and bleaching.
