Abstract: Abstract of the Disclosure A method for improving the utilization of the heat energy produced in a wood grinding process, wherein wood is ground in a grinding space (3) under a pressure exceeding atmospheric pressure, and warm shower water (G) is sprayed into the grinding space. The groundwood pulp (A) is fed from the grinding space into a steam separator (11), wherein the heat energy contained in the groundwood pulp is released in the form of steam (H), and replacement water (E) is brought into the process for the compensation of shower water losses. The steam separator is kept pressurized in order to recover the steam (H) released from the groundwood pulp under a greater pressure and at a higher temperature than in an atmospheric steam separator. The water addition (E) to the recovered shower water is warmed up by means of the pulp suspension (B) discharged from the steam separator, whereby the pressure of the steam is decreased from the pressure of the pulp suspension entering the steam separa-tor only so much as is required for heating the replacement water to a temperature which will bring the shower water to the desired temperature after  the replacement water has been mixed with said recovered shower water.

Abstract: ABSTRACT OF THE DISCLOSURE             A transceiver provides bidirectional optically isolated  communication  between  two  devices.  A  first output signal from the first device is input to the trans-ceiver.  Using parallel  optical  data  links,  an optical signal is generated in response to the first signal and is detected by a pair of  light  sensitive devices.  These light sensitive devices cause a second signal, representa-tive of the first signal,  to be generated.  The second signal is then conducted to the input  terminal  of  the second device.   In an alternate mode of operation,  the transceiver receives a third signal from the second dev-ice.  Using series optical data links, optical signals are generated in response to the third signal and are detected by light sensitive devices.  These light sensitive devices cause a fourth signal, representative of the third signal, to be generated.  The fourth signal is then conducted to the input terminal of the first device.  A control circuit cooperates with the parallel and series optical links to enable one and inhibit the other dependent upon whether a signal is to be communicated to the second device from the first  device,  or to  the  first  device  from the  second device.

Abstract: TITLE PREPARATION OF ALKYLENE CARBONATES                     ABSTRACT Alkylene carbonates, particularly ethylene carbonate, are prepared by the reaction of an alkylene oxide with carbon dioxide in the presence of a catalyst at temperatures ranging upwards from 20°C, particularly temperatures above about 90°C, preferably 90-170°C.  The conversion of alkylene oxide to alkylene carbonate can be carried out in the presence of water while minimizing the undesirable hydrolysis of the carbonate to the correspond-ing alkylene glycol and formation of higher glycols.  This is achieved by maintaining the water to alkylene oxide molar ratio and the carbon dioxide to alkylene oxide ratio within the stated limits and adjusting the carbon dioxide partial pressure to provide the desired selectivity to alkylene carbonate.
