Title: Method and apparatus for measuring the fibre orientation anisotropy in a fibrous structure
Inventor: BOULAY RUSSELL
IPC: G01N21/59
Filed: 1987-03-10
Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE:           A method and a device for measuring the fibre orientation anisotropy in a fibrous structure such as a sheet of paper or a textile.  According to this method, a linearly polarized, far infrared laser beam is directed towards one side of the fibrous structure whose fibre orientation anisotropy is to be measured.  The incident energy of the laser beam is measured before this beam traverses the fibrous structure, and its transmitted energy is measured on the other  side of the fibrous structure.  The transmission coefficient T of the laser beam is determined in at least two different orientations of the polarization plane of the beam with respect to the fibrous structure, this coefficient T being the ratio of the transmitted-to-incident energies.  This coefficient T varies exponentially with the basis weight of the fibrous structure and the ratio .alpha. of the absorption coefficients that can be derived from two measurements of coefficient T in two different orientations of the polarized beam, gives a quantitative evaluation of the amount of fibre orienta-tion anisotropy, the value  of this ratio .alpha. be equal to 1 when no anisotropy is present in the fibrous structure.

Title: Method of and control arrangement for selecting a control channel by a mobile radio station
Inventor: EIZENHOFER ALFONS
IPC: H04B7/26
Filed: 1987-04-02
Granted: 1990-09-18
Abstract: PHD 86307 13 19.02.1987 ABSTRACT Method of and control arrangement for selecting a control channel by a mobile radio station. Prior art radio transmission systems have base stations (BS) which in a geographical arrangement form a cellular system with overlapping radio zones. At least one control channel (CCH) and a plurality of speech channels are assigned to the base stations (BS). To avoid long search tuning times at any arrangement of the control channels (CCH) in the total overall frequency band of the radio transmission system, the base radio station (BS) transmits, at variable time intervals, references to the control channels associated with the base radio station to control channels of neighbouring base stations (3S) and to the substitute channel associated with the base radio station (BS) for the control channels. To avoid the necessity of a large number of such references to be used in an integrated services radio transmitting system each base station (BS) transmits with the object of informing the mobile stations (MS) of the structure of control channels (CCH) via a message transmission channel (COCH) references (NC) to message transmission channels (COCH) of neighbouring base stations (BS) and at least one reference (CC) to a control channel (CCH) assigned to the base station (BS), the message transmission channel (COCH) being a simplex transmission channel. The message transmission channels (COCH) are of a higher system hierarchy than the control channels (CCH), which renders it possible to enable access of several subscriber sets or subscriber sets of different services using only a small number of references.

Abstract: R4396.01 EAO: kaf LONG TIME CONSTANT INTEGRATING CIRCUIT                      ABSTRACT           A method and apparatus for performing integration  using a circuit capable of integrating an input signal over a wide linear dynamic range.  The circuit modulates the input signal with a biphase signal having positive and negative phases.  The modulated signal is then provided to an integrator. The integrator operates continuously within its linear range without needing charge dumping because the amplitude of the modulated signal is less than the amplitude required to saturate the integrator.  Each interval of the integrated signal corresponding to positive and negative phases of the biphase signal is then partitioned into intervals corresponding to the positive phases and intervals corresponding to the negative phases by two track and hold circuits with alternating tracking and holding periods.  The signal intervals corresponding to the negative phase of the biphase signal are subtracted from the intervals corresponding to the postive phases by a differential amplifier.  These subtracted intervals are then added together by a sample and hold circuit joined with a summing circuit to produce the integrated signal corresponding to the linear integration of the input signal.  The circuit is thus the mathematical equivalent of dividing the desired period of integration into a finite number of intervals, integrating each interval over that subdivided portion of the desired integration period, then adding the integrals of the intervals which equals the integral over the desired integration period.  The frequency of the biphase signal can be adjusted so that integration of the subdivided portions of the desired period of integration requires capacitors sizes capable of being incorporated onto an integrated circuit.

Title: Spring bow, centralizer, and related methods
Inventor: LANGER FRIEDRICH H
IPC: E21B17/10
Filed: 1988-05-20
Granted: 1991-07-30
Abstract: ABSTRACT SPRING BOW,  CENTRALIZER AND RELATED METHODS A centralizer for well casing functions  in  an annular space  between the casing and a wellbore. It comprises a pair of axially spaced-apart and aligned collars adapted to encircle the well casing and a  plurality  of  spring bows  extending between and secured to the collars. Each spring bow has two ends and an outwardly  convex  curved mid-portion.  In  a first form of the invention starting force  is  reduced  by  providing  spring  bows   having outwardly  projecting  contact  angle  reduction members that engage the upper edge of the wellbore as the casing is moved into  the  wellbore  to  reduce  the  effective contact  angle  of  the  spring bows with respect to the wellbore and thereby reduce the force required to insert the centralizer into the wellbore. In a second  form  of the  invention  the spring bows are provided with casing abutment  members   extending   inwardly   towards   the centralizer's  longitudinal  axis.  The  casing abutment members contact the casing as the spring bows are  moved towards  the  casing during insertion of the centralizer into the wellbore to increase the restoring force of the spring bows. The spring bows may have both contact angle reduction members and casing abutment members to give  a centralizer   having  a  desirable  combination  of  low starting force with high restoring force.
