Title: Method and apparatus for measuring physical adsorption of gasesbased on dielectric measurements
Inventor: BOSE TAPAN K
IPC: G01N9/00
Filed: 1988-08-30
Granted: 1991-08-13
Abstract: ABSTRACT          A method and apparatus for measuring physical adsorption of a gas by a solid adsorbent are disclosed.          Use is made of a capacitance cell in controlled gas flow communication with a sample cell initially under vacuum and containing the solid adsorbent.  The capacitance cell is filled with an adsorptive gas at a predetermined pres-sure and the dielectric constant of the gas at the prede-termined pressure is measured to determine a first densi-ty value.   The gas  from the  capacitance cell  is then allowed to expand into the sample cell for adsorption by the solid adsorbent,  whereby as adsorption takes place pressure  falls  until  equilibrium  is  established.   The dielectric constant of the gas at equilibrium pressure is measured to determine a second density value,   and the amount of gas adsorbed by the solid adsorbent is deter-mined from  the first  and  second density values.   The method and apparatus according to the invention enable precise measurement of gas adsorption at high pressures.          The method is simple,  self-sufficient,  easy to use and permits accurate measurement of the density of nonideal gases.

Filed: 1988-10-27
Granted: 1991-04-23
Abstract: ABSTRACT A vertical deflection current generator includes an operational amplifier responsive to an input sawtooth signal at a vertical rate. A first end terminal of a deflection winding is coupled to an output terminal of the amplifier.  A second end terminal of the deflection winding is coupled in series with a parallel arrangement of a switch and a capacitor.  The switch is conductive during vertical trace.  During vertical retrace, the switch is nonconductive, which causes a vertical retrace voltage to develop in a flyback manner in the retrace capacitor.  The retrace voltage in the retrace capacitor and a retrace voltage at the output terminal of the amplifier are opposite in phase and speed up the reversal of deflection current in the deflection winding.

Granted: 1993-10-12
Abstract: ABSTRACT OF THE INVENTION. There  is  provided  a  process  for screening an  agent   in  order  to determine whether  such agent increases the frequency of genome rearrangement in living matter. In the first step of this process, there is provided a viable species of Saccharomyces  cerevisiae yeast which comprises repeated genetic elements  in its  haploid  genome.  These repeated genetic elements are selected from  the group consisting of functional and non-functional genetic elements; and these elements are sufficiently homologous so that,  under ambient conditions, they recombine   with  each  other  and  give rise  to  an  identifiable   genome rearrangement which is a deletion. In  the second step of this process,  the viable species  of  yeast  is exposed  to the agent to be tested.   Thereafter,  it is plated onto a growth medium which,  after the exposed yeast species grows upon it, facilitates the identification of those yeast which have undergone said genome rearrangment. In the last step of the process, the extent to which the exposed species of yeast has undergone genome rearrangment is determined. Also disclosed is a the viable yeast strain used in said process, the plasmid used to construct said strain,  and a process for constructing   said strain.

Abstract: "TIME DIVISION SWITCHING FOR MULTI-CHANNEL CALLS USING TWO TIME SWITCH MEMORIES ACTING AS A FRAME                     ALIGNER"            ABSTRACT OF THE DISCLOSURE Signals on an incoming highway of a time division switching system are written into an alternate one of first and second time switch memories and are sequentially read out of the other alternate one of the memories into the time slots of an outgoing highway of the system in accordance with a phase difference between incoming and outgoing frames and a time slot interchanging relationship between signals on the incoming highway and corresponding signals on the outgoing highway, so that the beginning of the outgoing frame coincides with one of the time slots of the incoming frame which is displaced from the beginning of the incoming frame by an amount equal to the detected phase difference.  Alternatively, if the time slot of at least one signal of a multi-channel call on the incoming highway is later than the time slot of a corresponding signal on the outgoing highway, all signals of that multi-channel call are sequentially read out of the memories into a given outgoing highway so that they correspond to those on an incoming frame which is one frame prior to the one being written at the beginning of the given outgoing frame.  If the time slots of all signals of a multi-channel call on the incoming highway are earlier than those of respectively corresponding signal on the outgoing highway, all signals of that multi-channel call are sequentially read out of the memories into an outgoing frame so that they correspond to those on an incoming frame which is being written at the beginning of the outgoing frame.

Title: High purity bone mineral
Inventor: LUESSI HEINZ
IPC: A61L27/00
Filed: 1989-05-30
Granted: 1997-08-19
Abstract: The invention relates to an artificial bone mineral for use in medicine and to a process for preparing the same.  The bone mineral has a crystal structure and mineral microstructure substantially the same as natural bone and thus permits physiologically controlled, cell mediated remodelling on implantation.  The bone mineral, however, has an organic impurity content below 150 parts per million.   The bone mineral is produced by degrading and solubilizing degreased bone by heating with ammonia or a primary amine, and extracting the solubilized degradation products by washing with flowing water at temperatures below 60°C.  If necessary the degrading and washing steps may be repeated to remove substantially all of the organic matter.  The bone mineral, treated in this way, is then heated in air at temperatures between 250°C-600°C.
