Abstract: Abstract A method for moving a radioactive source into and out of a well logging tool incorporated in the drill string is disclosed.          Prior to moving the source, the logging tool is positioned sufficiently distant from and vertically under the drilling rig floor so as to avoid a hazardous radiation condition at the floor when the source is in its operative position in the tool.  A tubular radiation shield containing the source is positioned at the end of the drill string hanging from the rotary table and a source manipulating device is engaged with the source.  It is then lowered through the shield and the drill string into the tool.  These steps are practiced in the reverse order when the source is being removed from the tool.  An additional shield may be provided to envelop the first shield for added shielding during transportation or storage.

Title: Procedure for bleaching cellulose pulp involving the use of combined enzyme treatment and a bleaching process employing chlorine chemicals
Inventor: SALKINOJA-SALONEN MIRJA
IPC: C12S3/08
Filed: 1989-03-13
Granted: 1995-02-28
Abstract: The present invention concerns a procedure for bleaching cellulose pulp obtained from hardwood, wherein bleaching chemical containing chlorine is used.  The essential feature of the invention is that the residual chlorine content of the bleached pulp is reduced by subjecting the pulp to enzyme treatment. With the enzyme especially the removal from the pulp of chlorine-binding extractive substances present in hardwood pulp is promoted.  The invention furthermore concerns the use of enzyme towards lowering the residual chlorine content of bleached cellulose pulp made from hardwood.  Such cellulose pulp is particularly contemplated which will be converted into foodstuff package cardboard or paper, which are commonly disposed of by burning.  Lowered chlorine content reduces the risk of producing toxic dioxin at the incineration step.

Title: Filling level meter
Inventor: LAU JUERGEN
IPC: G01F23/28
Filed: 1989-04-12
Granted: 1992-02-18
Abstract: ABSTRACT             The filling level meter for measuring the filling level in a container includes a transmitting and a receiving arrange ment which directs sonic or ultrasonic pulses onto the filling material surface and receives the backscattered pulses reflected by the filling material surface and con-verts them to electrical reception signals.  Connected to the transmitting and receiving arrangement is an evaluating circuit which in a signal processing path generates an en-velope signal corresponding to the envelope of the reception signals, digitizes sampled values of the envelope signal, stores in a memory the digitized sampled values for creat-ing a distance-dependent or travel-time-dependent amplitude profile of the measurement distance and evaluates the ampli-tude profile for determining the travel time of the most probable useful echo signal.  Parallel to the signal pro-cessing path for generating the envelope signal, in the evaluating circuit a frequency detection of the echo signals is carried out by which echo signals having the transmission frequency of the sonic or ultrasonic pulses are determined. In dependence upon the result of the frequency detection the signal processing path is opened only for the echo signals having a frequency corresponding to the transmission frequency.  As a result all the reception signals having a frequency not corresponding to the transmission frequency are excluded from the digitizing and further processing. Due to the Doppler frequency shift these include all the reception signals which are caused by reflections at moving obstacles.  On the other hand, all reception signals having a frequency identical to the transmission frequency are passed on unchanged for the digitizing and further signal processing.

The prefetch control unit may reduce the prefetching of write commands stored in the first memory after the receipt of the first EWA signal.  Preferably, the prefetchings of write commands may be reduced when a write command sent from the host system is received.  After the prefetch control unit receives the first EWA signal, the number of prefetched write commands is limited, the final limit being determined by the recording density and the maximum block length of the write commands.  The running distance of the magnetic tape may be calculated and prefetch control performed until the calculated value reaches a value corresponding to a second EWA position corresponding to a position before the end marker of the magnetic tape.  When the value corresponding to the second EWA position is reached, an EOT signal is issued to the host system and prefetchings of write commands from the host system are no longer accepted.
