Two pairs of field plates are arranged in the air gap and when the carrier is moved the extent of penetration of the pairs of the field plates by the magnetic field is changed. The device also includes a bridge circuit by which the field plates are connected. The bridge circuit includes in one diagonal thereof a device for the display of measured values and is connected across the other diagonal thereof to a d.c. voltage.

Title: Microscope tube
Inventor: WESTPHAL KLAUS
IPC: G02B17/00
Filed: 1984-02-11
Granted: 1987-02-12
Abstract: A microscope tube having several sections articulated with respect to each other. A first stationary section (1) is hinged to a second section (2) which can swing upwardly and downwardly, and this is hinged to a third section (3) which hangs downwardly from the second section, the free lower end of the third section being swingable horizontally toward and away from the observer or user of the microscope. The third section has a fourth section (4) hinged to it to tilt on a horizontal axis, and this fourth section carries the eyepiece of the microscope. With this arrangement, the eyepiece may be adjusted to various positions vertically and horizontally to suit the comfort of the observer, and may be tilted to various viewing angles quite independently of its vertical or horizontal position. Mirrors within the tube at the hinge joints direct the optical beam properly from one section into the next section, and these mirrors turn through half the angle of swing when one section swings relative to the next. An additional optical system within the tube forms an intermediate image, and the observer sees the object in proper erect position in proper side-to-side relationship, rather than reversed. Provision is made for attachment of a camera or other desired auxiliary apparatus.

Title: Digital dynamic range converter
Inventor: STIKVOORT EDUARD FERDINAND
IPC: H03G7/00
Filed: 1984-02-03
Granted: 1987-06-11
Abstract: A digital dynamic range converter of the forward control type for varying the dynamic range of an audio signal which is available in digital form and is constituted by a sequence of audio signal samples. In the multiplier device 5, each audio signal sample x(n) is multiplied by a control signal sample s(n) which is delivered by a digital control signal generator 7. This control signal generator 7 has applied to it unipolar signal samples x(n) which are derived by means of a transmission channel 9 from the audio signal samples x(n).In order to cause this dynamic range converter to respond rapidly to abrupt variations in the audio signal and to render it moreover universally usable, the control signal generator is provided with a digital peak-value detector 11 which converts the sequence of unipolar signal samples x(n) into a sequence of peak-value samples x(n). The latter are applied to an adjustable digital non-linear amplitude transformation circuit 12 which has an adjustable amplitude transmission characteristic curve determined by adjustment quantities R and a. It delivers the transformation samples sin) which are preferably converted in a digital low-pass filter into the control signal samples s(n) which are applied to the multiplier device.

Title: Serial flow continuous separation process
Inventor: OROSKAR ANIL RAJARAM
IPC: B01D15/18
Filed: 1985-02-11
Granted: 1988-09-08
Abstract: A process for separating an extract component from a raffinate component contained in a feed mixture. A unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates. The units are interconnected in series so as to form a single closed loop. A component concentration distribution is established within the system of units so as to comprise a series of zones. Feed and displacement fluid are each mixed with a different intercolumn stream prior to being passed into the inlets of two of the units and extract and raffinate are taken only as portions of streams from outlets of two or more of the units at appropriate points on the component concentration distribution. At the appropriate times the inlets and outlets are shifted so as to simulate movement of the units in a direction downstream with respect to the direction of fluid flow and thereby enable the inlets and outlets to continually lie in the appropriate zones.
