Abstract: In the particular embodiments of the waste water treatment system described in the specification, a waste water treatment basin has spaced-apart, moving aerator chains extending across the basin in a direction transverse to the flow of waste water through the basin. When an aerator chain is provided with air, bottom aerators suspended from the chain adjacent to the bottom of the basin move with respect to the basin to mix sludge collected on the basin with the waste water and to supply air to the waste water. A control system supplies air selectively to the aerator chains to provide zones of full aeration and intermediate zones with little or no aeration and the selection of the aerator chains is changed periodically in a progressive manner along the basin so that the zones move progressively through the basin. As a result, sufficient air is supplied to the waste water in the basin for purification of the waste water and to maintain sludge in suspension as required in the waste water at minimum expense of energy. In addition, the oxygen potential of the waste water in the zones is controlled so that successive reactions relating to the purification process are accomplished in successive zones, for example, including nitrification of the waste water in zones having a relatively high oxygen potential and denitrification in adjacent zones having relatively low oxygen potential. Phosphorus removal is accomplished in a similar manner.

Abstract: A method for determining blood groups by the solid-phase method using blood group-specific antibodies and a carrier to whose surface the antibodies can be irreversibly bound is obtained by a solution of an antibody of the IgM type
 (a) either being contacted with the carrier surface simultaneously with the erythrocyte suspension to be determined or
 (b) the antibodies first being dried as reagent reservoir on the carrier surface and being dissolved, and thus contacted with the carrier surface, only by the addition of the erythrocyte suspension when the assay is carried out,
 and the determination being carried out a short time after the contacting, it being necessary that the antibody concentration is no higher than required to form an irreversible or immobilised layer of antibody molecules on the carrier surface, which layer is able specifically to bind erythrocytes, and is insufficient to bring about an agglutination reaction.

Abstract: An orbital shaker apparatus which has a tray for cyclic motion is flexibly suspended from a frame which is flexibly suspended from a plurality of stationary supports. The flexible suspension constrains the tray to move only translationally along one axis with respect to the frame and constrains the frame to move only translationally along one axis perpendicular to the tray movement axis. A single chip microprocessor is used to scan, input store, display and control the speed, duration and control functions for the orbital motion. Embodied in the software of the microprocessor is a real-time closed loop speed control which monitors the actual speed of the orbital motion thru an interrupt facility by calculating the duration of pulses received from an optoelectric sensor. The measured pulse duration is digitally compared to the desired duration and a digital control signal is provided to drive a DC motor which is directly coupled to the drive shaft which imparts the motion. A set speed mode and a reversing mode are selectable by an operator to provide different means for agitation.

Abstract: The disclosure relates to a method for endpoint detection in a semiconductor wafer etching ysstem characterised in the steps of: 1) scanning a semiconductor wafer (10) with a narrowly focussed laser beam (24); 2) analyzing a reflected portion of the beam to determine a preferred parking spot (P) on a preferred flat area (#8) of the wafer; 3) parking the beams at the preferred spot; and 4) analyzing the reflected portion of the beam to determine when the preferred flat area has been etched through. The beam spot (18) of the laser beam (24) is amller than the width of the preferred flat area to eliminate noise generated at the transition boundaries of the flat area. Preferably, the wafer is scanned several times along the same beam path to permit the comparison of several scans to determine the preferred parking spot. The apparatus includes a beam forming assembled (62, 64, 66); a scanning assembly which causes the laser beam to scan across the wafer; a detection assembly (76) responsive to a portion of the laser beam which is reflected off the wafer; and a controller (78) which operates the laser and the scanning assembly and which is responsive to an output of the detection assembly. When output of the detection assembly indicates a cessation of the characteristic etching curve, the controller develops an endpoint detection signal which can automatically shut down the etching system. <IMAGE>   <IMAGE>

Abstract: There is described a photographic element in which increased exposure latitude is obtained by having a dye-forming coupler in a non-light-sensitive interlayer between two light-sensitive silver halide emulsion layers. One of the silver halide emulsion layers is sensitive to a first region of the spectrum and contains a dye-forming coupler that forms a dye complementary in color to the region of the spectrum to which that layer is sensitive. The second emulsion layer is sensitive to a second region of the spectrum and contains a second coupler that forms a dye complementary to the second region of the visible spectrum. The exposure latitude in the layer sensitive to the first region of the spectrum is increased when the coupler in the interlayer forms a dye complementary in color to the second region of the spectrum, but as a function of development in the first region of the spectrum.

Abstract: A method and arrangement for electronically bandswitching a radio (100) is described which includes at least a receiver (110, 111), a PLL (120), and a fully synchronized, programmable counter as a frequency divider (140) that is coupled between the receiver and the PLL. This fully synchronized divider (140) provides an output signal (143) at a lower frequency with minimal harmonic energy and improves the sideband noise performance as the divisor increases. When the radio also includes a transmitter (104), stepped attenuators (128, 132) are also included for adjusting the modulation of the PLL (120) when in the transmit mode. The PLL includes at least a reference signal generator (121, 122), a phase detector (124), and a voltage controlled oscillator (127) having an output (129) coupled, via a feedback path, to a second input (131) of the phase detector (124). The fully synchronized, programmable frequency divider includes at least a counter, a data loader, a half-period detector, and a synchronizer which are configured and arranged to provide an output signal (143) having a duty cycle, nearly equal to 50%, which is independent of a divisor and which simplifies the filtering requirements thereafter, thereby providing electronic bandswitching for the radio while exhibiting fast-locking and low-noise characteristics.
