Abstract: Apparatus is disclosed for processing incoming scanning lines of video information having a nominal bandwidth for use with a bandwidth degrading path, such as magnetic tape. 
     A preprocessor includes a preprocessor comb filter (16) for comb filter processing of the incoming scanning lines to assure the presence of spectral gaps between energy groups in the spectrum of the video information. A fold over circuit (42) folds over high frequency luminance components of the video information about a predetermined folding frequency to provide folded video. A low pass filter (46) filters the resultant folded video to limit the spectrum thereof to be not generally in excess of one half of the folding frequency. 
     A postprocessor includes an unfolding circuit (66) for unfolding the signal from the path about the predetermined folding frequency. A postprocessor comb filter (68) processes the unfolded signal to eliminate unwanted alias components therein resulting during the unfolding process and provides a resultant video signal closely approximating the bandwidth and content of the original video information.

Abstract: An improved process is provided for the production of nitriles and oxides from hydrocarbons by reaction with oxygen, air or oxygen-enriched air, and ammonia where a nitrile is desired, in the presence of a suitable catalyst. An alkane, eg propane, is converted to an alkene in a multistage dehydrogenator. A stream containing alkene is withdrawn from a reactor in the dehydrogenator other than the first and the last reactor and introduced into an ammoxidation/oxidation reactor. The product is recovered in a conventional quench tower. The gaseous effluent from the quench tower is treated in a pressure swing adsorption unit to form a gas stream containing the unreacted alkane and alkene as well as a minor amount of oxygen. The gas stream, which may or may not contain hydrogen depending on the adsorbent in the pressure swing adsorption unit, is introduced into the reactor in the dehydrogenator following that from which the product stream was withdrawn. The effluent from the last reactor in the dehydrogenator is introduced into: the first reactor; an intermediate reactor wherein the alkene concentration closely approximates the effluent or the ammoxidation/oxidation reactor. The process operates particularly efficient when utilizing oxygen-enriched air in the reactor feed. A particularly preferred pressure swing adsorption system for use in the subject process comprises two parallel pressure swing adsorption units containing different adsorbents such that the gas stream formed in one contains all of the hydrogen in the gas phase from the quench tower. The feed to the pressure swing adsorption units is divided disproportionately so that the combined pressure swing adsorption effluent recycle streams contain the optimum concentration of hydrogen for the dehydrogenator.

Abstract: A process for the preparation of a high-bulk-density granular detergent composition or component comprises treating a particulate detergent composition in a high-speed mixer/granulator to effect granulation and densification to a bulk density of at least 650 g/litre, and subsequently admixing a small quantity of finely divided amorphous sodium aluminosilicate to the dense granular detergent composition thus obtained. This improves flow properties and raises bulk density further.

Abstract: Hemoglobin-based blood substitute resulted from stroma-­free hemoglobin, intramolecularly stabilized, modified with pyridoxal-5′-phosphate and subsequently polymerized under anaerobic conditions at an extent of above 40%. The new blood substitute is not toxic and possesses the proper oxygen affinity, adequate oncotic pressure and percentage of the undesirable methemoglobin, substant­ially equal to those of whole human blood. Among the main characteristic properties of the novel hemoglobin-based blood substitute the following may be mentioned: appropriate lifetime in circulation upon reconstitution in an appropriate solvent, good oxygen binding and delivery characteristics and appropriate oxygen transport capacity. The method for its preparation is simple and requires common reagents.

Abstract: A system controls power to multiple a.c. lighting loads from both a central location and from individual controls that are located near the loads. The system includes individual wallbox dimmers (26, 28) that include enabling switches, a master control (21), and isolation means (38) to accept input signals from the master control and to provide output signals to the dimmers. In a preferred embodiment, a dimmer also provides to the master control a signal that indicates the power being provided to the load that the dimmer controls. Preferably, the individual controls provide linear slide dimming, in which the power provided to a load is determined by the slider position. The system permits simplified installation and replacement of system components. Another system of the invention controls electrical power to multiple loads from both a central location and from local three-way controls. In one embodiment, the system includes means for sensing the power to each load. That sensing capability, in turn, permits the master to set all loads to the same power level, simultaneously, regardless of their original level. The local controls may be standard three-way dimmers or switches.

Abstract: A luminance video self keyer extracts (10), a key signal from an unshaped input video signal as a function of a low and a high clip level. The input video signal is subsequently "shaped" (12,18) as a function of the key signal and the low clip level. The result is a shaped video signal and an associated key signal that are combined (16) with a secondary video signal without resorting to double multiplication of the input video signal by its associated key signal to produce a desired combination of the two video signals.

Abstract: An adjustable but constant flow of liquid is maintained by the pump B1, at a pressure which can, if necessary, be considerable, from a liquid reservoir A to the multifunction reservoir in service M O, and then, at a low pressure, to one of the storage reservoirs U. Depending on the flow rate of the suspension metering device E, the flow feeds the closed suspension reservoir which is in service D, or only the boiler G, or both. Heating takes place at G, temperature maintenance at I, deflection at K, hot sedimentation at M, sedimentation, cooling and temporary storage at O while the excess of liquid of M O, cooled at Q2 and expanded at R, flows via S T towards a storage reservoir U which is preferably flexible and immersed. The transfer of particles from M O towards U takes place hydraulically while another multifunction reservoir M O receives the stabilised and hot suspension. Settling takes place at M, at O, then at U. The excess cold liquid at the top of U is cycled, via S' and the pump B4, towards the reservoir M O, from where the particles are to be transferred towards U. The cycling device makes it possible, when not in operation, intimately to mix the liquid in a reservoir, between several storage reservoirs and even to increase its content of dry matter by introducing sugar syrups or other concentrated matter, using special flexible reservoirs. <IMAGE>
