Abstract: The method is intended especially for video signals in which so- called coefficient blocks occur as an intermediate signal. The majority of the signal values belonging to a coefficient block - also referred to as coefficients - are 0. For this reason, an uninterrupted sub-string of zeroes is combined with the subsequent coefficient to form an event, provided that the length of the sub-string of zeroes remains below a maximum value. Once the maximum value has been reached, this maximum sub-string of zeroes, along with the subsequent coefficient, is regarded as an event and subsequent coefficients are combined to form further events. A Huffmann code word is allocated to each event for transmission purposes. To form events from the coefficient string, the coefficients are fed via an input line (e) to a comparator circuit (K) and to the address inputs of a memory (PROM). The count of a counter (Z) is supplied to further address inputs of the memory (PROM) and also to the comparator (K). If a coefficient on the input line (e) is 0, the comparator sends a counting pulse to the counter (Z), provided that a maximum count has not yet been reached. If the coefficient at the input (E1) of the comparator (K) has a non-zero value, or the maximum count has been reached, the comparator (K) sends a reset pulse to the counter (Z), with which the code word occurring at the memory (PROM) is simultaneously transferred into a flip-flop circuit (FF).

Abstract: An optical switch apparatus comprises two optical waveguides 3 and 4 formed by diffusing titanium into a lithium niobate body. Flat electrodes 7 and 8 are bonded to the surface of the body 2 arranged such that an electric field may be applied across the body. This enables the distance between the waveguides 3 and 4 to be changed depending on the field applied and hence produces a change in the coupling constant of the waveguides 7 and 8, thus the switching response of the switch may be enhanced.

Abstract: An apparatus for reproducing a pulse-code-modulated signal comprises error-correction means (3) for correcting errors in one or more of the data words forming the pcm signal. When the error-correction means are no longer capable of correcting errors in the pcm signal, they produce error flags on an output (7), which error flags are applied to a control unit (9). From these error flags the control unit (9) derives a control signal which is applied to a muting unit (6) for switching on the muting unit. A method is described by means of which the cont es the control signal from the error flags applied to its input (8). A first auxiliary signal (S1) is generated if (at least) n1 error flags are detected within a first time interval (T1) Subsequently, an i-th auxiliary signal (S i) is generated if (at least) n i error flags are detected within an i-th time interval (T i) which occurs after the instant at which the (i-1)-th auxiliary signal appears. The value of i ranges from 2 to N inclusive. Subsequently, a control-signal generator generates the control signal during a time interval T m which occurs after the instant at which the N-th auxiliary signal is received (Fig.2). A number of examples of the control unit are described.

Abstract: Two follistatin proteins with inhibin-like activity were isolated from porcine follicular fluid using heparin-Sepharose affinity chromatography, followed by gel filtration on Sephacryl S-200 and then six steps of high-performance liquid chromatography. Each isolated molecule is a monomer having a molecular weight of at least about 32,000 daltons. Microsequencing revealed the NH2-terminal portions both to be Gly-Asn-Cys-Trp-Leu-Arg-Gln-Ala-Lys-Asn-Gly-Arg-Cys-Gln-Val-Leu. The larger protein has 315 residues and is believed to be glycosylated. The smaller protein is a 288-residue, C-terminally shortened version thereof. These proteins specifically inhibit basal secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system. The Half-maximal effective dose for both is 2.5-6.0 ng/ml. Human and rat follistatins exhibit very high homology with the porcine protein, with the human differing from porcine in only 4 residues out of 315 and with the rat differing from porcine in only 8 residues out of 315.

Abstract: A video distribution system (e.g., CATV or MATV) employs at least one channel having a reception-defeating jamming signal which changes frequency periodically or, preferably, randomly. The signal originating head end distributes information characterizing the operative frequency of the jamming wave. At controller apparatus for authorized viewers, the jamming frequency specifying data is employed on a frequency agile basis to heterodyne the protected channel into a proper (fixed) frequency relationship with a notch band suppression filter to remove the jamming signal. The secure channel with the jamming wave removed is then again shifted to its original or other intended frequency to permit normal reception either directly by a standared television receiver, or via a frequency converter.

Abstract: Method and aparatus for production of a gas from a comminuted biological waste material, such as straw, in which method the comminuted material is introduced into a reactor through a gastight lock possibly with an addition of steam and distributed into a bed of catalytic bodies, which are moving in such a way that the material during the gasification is flowing along a predetermined path as the produced gas and the residual material are removed through the bottom of said bed. In order to produce a gas of high calorific value and without tar and to prevent the surfaces for heat transmission from tar deposits, and to prevent formation of residual material from the gas production that contains substantial amounts of compositions, which are unacceptable to the environment, the method is characterized in that the bed is heated indirectly, and that the agitation of the catalytic bodies is provided by such a vibration of the bed that the material is conveyed downwards through the bed, the filler bodies being ceramic carriers for a catalytically acting heavy metal.

Abstract: The invention relates to a method and a device for reducing scale formation and/or corrosion in systems which conduct liquids or are in contact with liquids. According to the invention, this is achieved without reducing the quantity of hardness constituents contained in the liquid overall, without exchanging the hardness constituents in the liquid for other cations such as e.g. hydronium, sodium or potassium and without adding chemicals such as e.g. phosphates which inhibit scale formation to the liquid. Instead, scale formation is reduced by specifically shifting the molar distribution of the hardness constituents, especially the distribution proportions of the individual hardness constituents magnesium and calcium strontium and barium. According to the inventive method, proportions of the hardness constituents calcium, strontium and barium in the liquid are substituted with the proportions of the hardness constituent magnesium, In addition to efficiently reducing scale formation, the method inhibits corrosion processes in systems which conduct liquids or are in contact with liquids and reduces the extent of these processes.

Abstract: A method for operating an ad-hoc network for the wireless data transmission of synchronous and asynchronous messages synchronizes the transmitters and receivers of neighboring nodes on a transmission path using cyclically transmitted identifiers, whose intervals define a time frame. The nodes of the transmission path reserve time slots within the time frame for the transmission of data packets of a virtual connection that are to transmitted synchronously. A start signal is transmitted at the stars of the synchronous transmission of a virtual connection, the data packets are then transmitted in the previously defined time slots and the synchronous transmission is concluded by a stop signal. Free time slots in the nodes are filled with data packets that can be transmitted asynchronously, the packets being read from an output buffer memory of the node.
