Abstract: In a centrally-vented multi-cell battery, a porous fritting body (2), which is enclosed in a plastic capsule (1) and is used for explosion protection, is arranged so as to be removable in a chamber- like expansion (3) of the vent line (4) which is guided in the battery cover (5). The capsule additionally contains a valve, which is located in front of the fritting body (2) - seen in the gas outlet direction (7) - and protects the latter from electrolyte mists produced by the charging gases. Moisture which is nonetheless absorbed by the fritting body can fall out downwards from the actual flow cross-section, because of its vertical arrangement, so that it is unnecessary to increase the flow resistance by blocking the pores.   <IMAGE>

Date Dec. 1, 1988.When signals from an incremental transmitter are being evaluated, noise may distort the signals and the subsequent stages connected to the transmitter may therefore be incorrectly controlled. The invention discloses a process for suppressing the noise, thereby permitting correct evaluation. In the process, the signals at the outputs of the incremental transmitter are sampled at high frequency and stored in an intermediate store. They are then checked to ascertain whether a predetermined sequence of output signals exists. Since this predetermined sequence is not respected in the event of interferences, no signal is produced. A signal is produced only when the predetermined sequence is respected. The process can be applied wherever it is desired to obtain an undistorted output signal using an incremental transmitter of simple design.

Abstract: The invention concerns a procedure for the bleaching of pulp using an oxidating bleaching chemical containing chlorine. The essential features of the invention are that the chemical used in the oxidation stage has a chlorine dioxide content of at least 50 %, that the pulp is subjected to enzyme treatment either in conjunction with or before the oxidation, and that, after the oxidation and enzyme treatment, the pulp is treated with an alkali. The use of enzymes reduces the amount of chlorophenols and other forms of organically bound chlorine in the spent bleach liquor, simultaneously lowering its chemical oxygen demand.
