Granted: 1985-07-31
Abstract: An inexpensive cation exchanger useful in purifying waste water is produced by treating comminuted bark in separate steps with an alkali hydroxide solution of at least 5% by weight, preferably 20-40% by weight, and with 30-75% by weight sulphuric acid, preferably 50-65% by weight. After each step washing with water is performed until the pH-value after the alkali hydroxide treatment goes below 9 and after the sulphuric acid treatment goes above 3. Preferably, the treatment with alkali hydroxide precedes the treatment with sulphuric acid. The treatment with alkali hydroxide is carried out for 0.5-20 hours, preferably 3-10 hours, and the treatment with sulphuric acid is carried out from 0.5-8 hours, preferably from 1-6 hours. The cation exchanger can be regenerated with alkali hydroxide solution, particularly sodium hydroxide solution.

Abstract: Eyeglass lenses for persons suffering from severe ametropia. The lenses have a convexly shaped object-side front surface (4) and an eye-side rear surface (3) which is aspherically corrected in the central region (6) which comprises at least the main field of view. From this region the rear surface passes into a region in which its meridional inclination approaches the inclination of the front surface. The entire rear surface of the lens is continuously differentiable twice. Such a lens has an appearance which is fully satisfactory esthetically and makes it possible to keep the overall magnification of the system consisting of the eye and the eyeglass lens closer to 1 than in the case of previously known lenses. Aberrations are optimally corrected within a sufficiently large region, and no disturbing discontinuities in the fields of view occur.

Abstract: A roller for heat- and/or solvent-treatment of fibrous materials has circumferentially extending annuli or spirally arranged rows of coherent or discrete neighboring protrusions each of which has a larger frustopyramidal section nearer to and a smaller frustopyramidal section more distant from the peripheral surface of the cylindrical body of the roller. The taper of facets of the smaller frustopyramidal sections is less pronounced than the taper of the facets of the larger sections, and the distance between the bases of two neighboring larger sections is less than half the height of a protrusion. The top lands of the smaller sections are relatively large and, due to the less pronounced taper of the facets of such smaller sections, the top lands can be reground a large number of times without unduly increasing their areas so that the rate of transfer of heat from the cylindrical body to the top lands and thence to the adjacent fibers is not unduly affected by repeated grinding. The heights of the smaller sections is less than the height of the larger sections. This also promotes satisfactory transfer of heat from the cylindrical body, through the larger sections and to the top lands of the respective smaller sections.

To eliminate this drawback, the screen is formed in such a way that at least half of all outwardly disposed longitudinal knuckles of the upper fabric (paper-facing side) of the screen are formed of two sets of longitudinal threads and that the first set of longitudinal threads is woven with the first set of cross threads, the third set of longitudinal threads is woven with the second set of cross threads, and at least portions of the second set of longitudinal threads are woven with both sets of cross threads.

A recurrence formula computing section executes a DP matching recurrence formula computation in accordance with a plurality of values read out of the work memory and the distance resulting cumulative distance. The control operator and the position at which the control operator appears is stored in a stack and a stack processing section has a stack control section which, when the control operator is detected, conducts the PUSH/POP operation of said stack in accordance with the kind of the detected control operator, thereby to control the DP matching recurrence formula computation which is to be conducted in the recurrence formula computing section. This pattern matching apparatus can deal with various possible deformations of the pattern even with reduced capacity of the reference pattern memory. Furthermore, the apparatus is most suited to the continuously uttered words recognition in synchronism with the input speech.

Abstract: Control apparatus for a stepping motor driving a peristaltic pump comprises a presettable downcounter for supplying drive pulses to the stepping motor at different repetition rates so as to regulate the speed of rotation of the motor, processing means for controlling the downcounter so that the motor is normally operated to drive the pump at a predetermined pumping rate, and a sensor for detecting indexing marks at spaced positions about the pump head, the processing means being responsive to the sensor detecting the index marks to alter the count in the downcounter so as to increase the motor speed for a predetermined number of motor steps upon detection of each index mark. After the predetermined number of steps at increased speed, the processing means resets the downcounter to its normal setting, so that the motor operates at the required pumping rate for a further predetermined number of motor steps and until detection of the next successive index mark of the head. Hence, the drive motor rotates or skips more rapidly during alternate periods corresponding to dwell periods of the peristaltic pump when reduced or no fluid flow would normally occur and, consequently, the pump delivers fluid at a more constant flow rate.

Title: Method and apparatus for applying and monitoring programmed test signals during automated testing of electronic circuits
IPC: H03K5/00
Filed: 1984-08-01
Granted: 1988-06-01
Abstract: A timing subsystem 10 including several test period generators for supplying a variety of timing signals to a device under test. Major, minor, and free-run period generators each supply various timing signals to a multiplexer 18, which selectively connects the timing signals to timing generators 20. A central processing unit 28 supplies data to the period generators and timing generators to define their respective timing signals. Timing signals generated by the major period generator 12 define the overall testing rate. The minor period generator 14 generates multiple timing signals within the periods of the major clock signals to permit higher clock rates. Timing signals that are independent of the major clock periods are generated by the free-run period generator 16. An external synchronizer circuit 26 provides a feedback loop from the device under test 22 to the major period generator. A reference driver trigger delay circuit 27 provides means for calibrating the timing generators. Each of the three period generators includes two interconnected timing interval generators 30 and 40 that alternately generate overlapping timing signals. Each timing interval generator includes a stop-restart oscillator 32, a counter 34, and a delay-line vernier 36. Upon the receipt of a start signal, the oscillator stops and restarts to align its clock pulses to the start signal. The oscillator output clocks the counter, which supplies a signal to the vernier when a preselected number is reached. The vernier delays the counter signal by a preselected delay and issus a signal that designates the end of the period.
