Abstract: The remote ends of two pairs of conductors forming a four-wire circuit are directly connected. A phonic signal is applied to the near end of one pair of conductors, and the logarithmic level of resulting signal is measured at the near end of the other pair of conductors. A compandor, adapted to reduce the logarithmic level of a signal by a fixed division factor is then inserted between the remote ends, and a phonic signal is again applied to the near end of one pair of conductors and the logarithmic level of the resulting signal is then measured at the near end of the other pair. Mathematical relations are used to obtain the overall loss for each separate pair of conductors.

Abstract: The biological treatment of waste water is carried out in a cascade disc aerator system designed for the oxidation of nitrogen compounds.   The invention provides for the direction of flow of the waste water to be purified being reversed from time to time. The essential advantage is that the merits of the cascade disc aerator system with longitudinal flow are utilised without it being necessary to put up with the disadvantages. The reversal of the direction of flow has the effect that high population densities of nitrogen-oxidising bacteria are achieved in all cassettes. Bacteria which are in a fasting state during one phase of operation receive an adequate supply of substrate again after the direction of flow is changed. High densities of bacteria on all items in the bed permit, on the one hand, a higher nitrification efficiency of the overall system and, on the other hand, a distinct improvement in the process stability when the waste water ratio is changed, compared with known procedures. <IMAGE>

Abstract: An adjustable table (T1) of this type is mounted on a fixed base member (G1) by means of three identical adjusting elements (V1) which are arranged in rotational symmetry to the centre of the adjustable table (T1), at the periphery thereof. The adjusting element (V1) consists of a threaded bolt (GB1) in a threaded bore (BB1) of the adjustable table (T1) and of a supporting element (SE1) which rests in a freely displaceable manner on the surface (OG1) of the fixed base member (G1). The threaded bolt (GB1) has a convex spherical surface (FV1) at one end which engages in a concave spherical surface (FS1) of the supporting element (SE1); the other end of the threaded bolt (GB1) possesses a slot (S) for the engagement of an adjusting tool to adjust the distance and/or the angular position of the adjustable table (T1) relative to the fixed base member (G1). To increase rigidity, a tension spring (Z) is assigned to each adjusting element (V1) between the adjustable table (T1) and the fixed base member (G1). To avoid de- centring and twisting during adjustment of the adjustable table (T1), a strut (ST1) with two flexural joints (BG1) is fixed to the adjustable table (T1) and to the fixed base member (G1) by its two ends between each pair of the three adjusting elements (V1). <IMAGE>

Abstract: The semiconductor amplifier circuit has at least one amplifier stage of four transistors (T1, T2, T3, T4), two of which in each case operate in push-pull mode, in which the gain characteristic is improved, particularly for normalised signals. For this purpose, the first transistor pair (T1, T2) at the input, at the interconnected bases of which the input signal (UE) is present, is operated as impedance converter, and the further transistors following each transistor (T1, T2) in each case operate as current source and operate in push-pull mode with one another. There is a pair of diodes (D3, D4) connected in parallel in opposite directions which is connected via a capacitor (C5) from the output of the amplifier stage to earth. The invention can be applied particularly in the case of amplifiers for connections to bus lines in data transmission. <IMAGE>

Abstract: A zero-IF receiver for an FM signal comprises quadrature-mixers (2,3) to which the input signal is applied and which mix the received carrier down to zero frequency. The signals appearing at the mixer outputs (11,12) are fed to a differentiate, multiply and subtract demodulator (22,23,25,27,31) via capacitors (17,19) which block the d.c. components of the signals, thereby preventing amplifier saturation effects, etc This d.c.-blocking would, unless steps were taken to prevent it, result in distortion of the output signal appearing at an output terminal (32). This distortion is prevented by providing an amplitude divider (33) in the output signal path. The signal fed to the divider control input (48) is derived from the output signals of the blocking capacitors by squaring them by means of multipliers (37,40), adding the results together in an adder (43) and applying the adder output signal to the control input (48) both directly and via a low-pass filter (46) the cut-off frequency of which is equal to that of the high-pass filters (15,16) of which the blocking capacitors effectively form part.

Abstract: An apparatus and method are provided for disabling the clocking of a processor in a battery operated computer during non-processing times. The clocking is disabled at the conclusion of a processing operation. The clocking can then be re-enabled using interrupts from any one of a plurality of sources, such as an I/O device or a direct memory access. Application programs and operating system programs running on the system can specify the stopping of the system clock and the central processor until a specified event which had been requested occurs, or until an optional time-out period has expired. In this situation, the event is defined as one that results in either a system interrupt from an I/O device or from a direct memory access operation. The stopping of the system clock is a two part operation wherein in the first part the stopping mechanism is first armed. If an interrupt is received subsequent to arming, then it will be processed and the arming mechanism will be reset. However, if an interrupt does not occur after arming within a specified time period, then the system clock will be stopped.

Abstract: It has been determined that 1,2,3-trialkoxybenzenes and 1,2,4-trialkoxybenzenes can be utilized in order to increase the vinyl content of polydienes which are prepared utilizing lithium catalyst systems. For instance, it has been determined that 1,2,3-trimethoxybenzene and 1,2,4-trimethoxybenzene are very strong modifiers for utilization in such polymerizations. The utilization of the trialkoxybenzene modifiers of the present invention is highly advantageous because they promote fast polymerization rates and can be used to produce polymers having high vinyl contents.

Abstract: This method comprises a preprocessing of the signals by means of a block-by-block transformation method, in which preprocessing both a transformation and the formation of a difference between a signal which is generated at a time t-1 and has been stored in a frame buffer and a signal which is produced at a time t are carried out so that the preprocessing forms a transformed frame-to-frame prediction error signal, the prediction error signal thus formed being subjected to a scalar quantisation, a number ND being determined from the quantised prediction error signal which corresponds to the parallel of the secondary diagonal in a coefficient matrix up to which, starting from a direct component, significant coefficients are contained and which number is used for reducing the number of coefficients to be transmitted, which number ND is also transmitted. The prediction error signal is also subjected to a vector quantisation and the representative block selected by this means is indirectly transmitted by means of its index which represents its address in a code table. The representative block is subtracted from the quantised prediction error signal in order to achieve by this means a reduction in the energy of the signal to be transmitted. <IMAGE>

Abstract: This invention provides a matrix composition for sustained drug delivery which is comprised of an active agent, a hydrophilic polymer and an enteric polymer. The enteric polymer is impermeable to gastric fluids and aids in retarding drug release in regions of low pH, thus allowing lower levels of hydrophilic polymer to be employed. At the pH range of intestinal fluids, this polymer will dissolve and thereby increase the permeability of the dosage form. This approach is useful in sustaining the release of numerous active agents whose solubility declines as the pH is increased, a characteristic of weakly basic drugs. By responding to changes in physiological pH, these sustained release dosage forms have acceptable performance, in spite of variability in the gastrointestinal transit times of the formulation.
