Title: Method and device for indicating the contact position  in a refiner
Inventor: KERBLOM BENGT
IPC: D21D1/30
Filed: 1988-09-28
Granted: 1993-09-21
Abstract: Abstract In a disc refiner with two opposed refining discs (1,2) rotary relative to each other the contact position for the refin-ing surfaces (9,10) is indicated.  The refining discs (1,2) are moved against each other during relative rotation whereby the first contact of the refining surfaces (9,10) with each other generates a heat radiation, which is detected by a transmitter (15).  The place of detection is radially outside the refining discs (1,2) in a refiner housing (12) enclosing the refining discs.  Said transmitter emits an output signal, which is utilized for determining the contact position.

Title: Data security arrangement for an automated magnetic tape cartridge library system
Inventor: MUNRO FREDERICK G
IPC: G11B17/22

Granted: 1993-10-12
Abstract: DATA SECURITY ARRANGEMENT FOR AN AUTOMATED MAGNETIC TAPE CARTRIDGE LIBRARY SYSTEM                      ABSTRACT This  data  security  arrangement  provides  a significant level of data security in an automatic magnetic tape cartridge  library by  isolating the actual data from the control of the data retrieval process.  This isolation is accomplished by the use of  a  plurality  of  architectural  devices  that dissociate control and data.  The data written on the magnetic tape cartridges cannot be accessed by the library  modules.    The  library  modules  are  not electrically connected to the tape drives or the data bus  that  connects  the  tape  drives  to  the  host computer.  In addition, library software on the host computer emulates an operator's console and intercepts all  tape  mount  commands  generated  by  the  host computer.   The library software translates these commands into control signals to activate the library module  to  retrieve  a  designated  magnetic  tape cartridge and load this cartridge into a tape drive. Thus, the data retrieval apparatus is separate from the library control apparatus.  The library module is unaware of the identity of the data stored on the magnetic tape cartridges and the host computer is unaware of the existence of the automated magnetic tape cartridge library.

Title: Method of cultivating living cells and bioreactor therefor
Inventor: DAVIDS STEPHEN J
IPC: C12N1/00
Filed: 1989-03-14
Granted: 1993-08-10
Abstract: ABSTRACT OF THE DISCLOSURE       In a bioreactor, oxygen is supplied to a suspen-sion of living cells using a carrier liquid in which the oxygen is soluble.   The carrier liquid is immiscible in the culture medium and has a specific gravity greater than that  of  the  culture medium,  so  that when  the  oxygen bearing  carrier  liquid  in  injected  into  the  culture medium,  it will give up its oxygen and coalesce at the bottom of the reactor.   The carrier liquid is oxygenated through a membrane to avoid contamination.  The oxygenator may be temperature controlled to control the temperature of the carrier liquid and thus the culture medium.   The concentration of carbon dioxide may also be controlled to ensure that it does not become excessive.  The reactor may carry out either batch processes or continuous perfusion.

Abstract: Abstract A method  is  provided  for  determining  the  state of wear of a multicone  drill  bit.   Vibrations generated by the working drill bit are  detected  and converted into a time oscillatory signal from which a  frequency  spectrum  is  derived.  The periodicity of the frequency spectrum  is  extracted.  The rate of rotation of at least one cone is determined  from  said periodicity and the state of wear of the drill bit  is derived from  said  rate  of cone rotation.  The oscillatory signal  represents  the variation  in  amplitude  of  the vertical or torsional force applied to the drill bit.   To  extract  periodicity,  a  set  of  harmonics  in the frequency spectrum  is  given  prominence  by  computing  the  cepstrum  of  the frequency  spectrum  or by  obtaining  an harmonic-enhanced spectrum.          The  fundamental  frequency  in the set of harmonics is determined and the rate of cone rotation is derived from said fundamental frequency.
