Abstract: There is described a comb-line band-pass filter with circular cross section made up of internal rods (A1 to A5) constituting the resonators of the filter and brought to resonance by the use of tuning screws (S1 to S5) and alternating with coupling screws (V1 to V4). In the filter the rods (A1 to A5) are inserted in such a manner that each one is rotated in relation to the preceding one by an angle of 0° < α < 90° while the coupling screws (V1 to V4) are placed at an intermediate angle. For equal electrical characteristics the length of the filter is also a function of the rotation angle of the rods (A1 to A5)

Abstract: A process for treating gases which contain non-metal oxides and/or hydrogen halides is proposed, wherein the gases are, after cooling and admixing of alkaline reactant, passed through a reactor, contacted therein with a solid adsorbent having a large outer cooled surface and a temperature lower than that of the gas, and the reaction products formed are then removed in the dry state from the gas and removed from the adsorbent by oxidation and/or mechanical abrasion and are then finally separated in further process steps from the gas to be treated and from the working gas used. The reaction products which have been separated out can be used further as a fertiliser raw material. The advantage of the process and of the equipment used therein is that the entire treatment of the gas can be carried out in the dry state and at a low energy level.

Abstract: An erase bar for a xerographic printer, copier or the like has a row of light emitting diodes (16) for illuminating a row of pixels across the photosensitive medium of the printer. Each LED (16) is located in the bottom of a cavity (26,27). Next to the bottom of the cavity (26,27) are concave relective walls (29,31) which reflect light emitted transversely from the LED (16) toward an open end of the cavity. Reflective walls (27) of the cavity provide multiple bounces of some of the light. Absorptive walls (26) nearer the open end of the cavity (6,27) absorb some of the light. These features combine to illuminate a pixel of desired shape and with approximately uniform intensity of illumination. Additional uniformity may be provided by passing the illumination through a window (36) that is at least partly absorbing (38) for smoothing out differences in intensity.

Abstract: A method for generating an input quantity for a crossed-coil indicating instrument from a measurement signal is specified in which the frequency of the measurement signal is converted into a frequency-proportional input current for the crossed-coil indicating instrument (11). Furthermore, a circuit arrangement is specified in which an input connection for the measurement signal is connected to a period measuring device (3, 4, 5) the output of which is connected to a dividing device (6), the output of which feeds a control variable proportional to the frequency of the measurement signal (fM) into an input (13) of a processing circuit (8, 10). The disadvantageous factor in the known method and the known circuit arrangement is the fact that an abrupt movement of the pointer of the indicating instrument (11) can be observed at a low frequency of the measurement signal. To eliminate this abrupt movement, an input current, which controls the crossed-coil indicating instrument (11) to a predetermined value independently of the actual frequency is generated below a predetermined first frequency value of the measurement signal. …<IMAGE>…

Abstract: 2.1 Electric time-controlled combination locks for entertainment electronics devices are known. To block the reproduction or the reception of a particular television transmission at the television receiver (childproofing), the user enters an additional codeword with the data which are required for programming for reception of the television transmission. Data and codewords are entered into a memory and a control device arranged in the set compares the stored codewords or data with the currently entered codeword or received data of the television transmission. 2.2 To enable even an unskilled user to block the reproduction of particular television transmissions in a simple manner, the corresponding data are automatically taken by means of data decoder or videotext decoder and, together with the codeword entered by the user, supplied to the memory. The control device also takes into consideration transmitter-controlled reprogramming or also provides for automatically blocking sets of a combination of sets. 2.3 The novel device utilises transmitter-controlled aids in a surprisingly simple manner for preprogramming a receiver in conjunction with childproofing. <IMAGE>

Abstract: A digital mixer (20) is supplied with two digitized input signals in complex form. The product of the complex input signals is converted to analog form and provides the desired output signal without any alias terms. The first input signal is desirably stored in a first memory (18) as a sequence of data points corresponding to a complex exponential sinusoid. The second input signal is a baseband excitation waveform that is also stored in complex form in a memory (14). Operands from these two sources are provided periodically to the mixer for complex multiplication. The sequence of sinusoid operands provided from the first memory is determined by a phase counter that indexes through the memory by a Δϑ term. Δϑ is selected so that the data indexed thereby corresponds to samples of a sine wave of the desired frequency. If Δϑ indexes a signal phase intermediate two complex data in the memory, an interpolated value is provided.

Abstract: A selectively tunable coherent optical receiver includes a tunable laser for producing a selectable local oscillator frequency for receiving any one of a group of received optical channel signals. The tunable laser is controlled by a feedback loop and a digital processor that stores values of laser bias current. The arrangement produces an exact local oscillator frequency for operating with any one of the group of selectable received channel signals which are spaced over a range of optical carrier frequencies. This receiver avoids frequency sticking and very long pull-in time and determines when there is a missing channel or missing channels.

Abstract: Disclosed is a unique vehicle system which provides a desirable rheology to products formulated therewith, enhanced dispersion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long-chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-soluble polymer having a molecular weight greater than about 20,000, preferably a natural polysaccharide, dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent, may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the skin or hair. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.

Abstract: An apparatus is used to perform a fabrication procedure on a microcircuit under control of specification data. The procedure may include making relatively undetectable modifications to the microcircuit using a focussed ion beam to deter unauthorized reproduction and/or use of the microcircuit. The output of the apparatus is tapped to generate record data of the signals actually applied to control the focussed ion beam to perform the procedure. The record data is written into at least one verification data storage area of the microcircuit, preferably using the focussed ion beam. During testing of the microcircuit, the data written into the storage area is read out and compared with the specification data and generated record data. Proper performance of the procedure is verified if the compared data correspond to each other.
