Abstract: ABSTRACT "Receiver for angle-modulated carrier signals."     In mobile radio communication it often happens that the received signal disappears owing to, for example, fading.  If a receiver is used which is based on the coherent detection principle acquisition of the carrier must consequently be done repeatedly.  In order to avoid the loss of information resulting therefrom non-coherent detection is used in the receiver for angle-modulated carrier signals in combination with a decision criterion which is based on the possible phase traject-ories of the demodulated signal.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for operation of a carboniza-tion or coking plant, with which coking furnaces are periodic-ally charged with pre-heated coal and the obtained coke under-goes a dry cooling by means of a gaseous cooling medium, heat discharged from the coke dry cooling being used directly or indirectly for pre-heating of the coal, with the coal preheating accomplished using a travelling bed drier, having a heat exchange tube which is heated with hot gas or waste-heat vapor from the coke dry cooling.  Preferred embodiments include withdrawing exhaust gas-containing vapors produced in the travelling bed drier from different levels thereof, cleaning, cooling and con-densing them and then disposing into a waste water discharge; superposing a fluidized bed drier upon the travelling bed drier, and initially heating the coal in the former to a temperature between about 60 and 100°C, thus drying the coal only to the extent that a sufficient flowability is ensured in the travell-ing bed drier, in which the coal is then heated to a final temp-erature of about 200°C and dried to a residual water content of about 0.1% by weight; supplementing the heating of the driers with flue gas produced by combustion of a fuel in a separate combustion chamber, and admixing steam to adjust the gas temper-ature.  The travelling bed drier possesses a heat exchange tube within a frame, the tube displaying a surface increased through suitable design such as fins or ribs, a conical tapering in the direction of the coal feed, and discharge connections located at different levels on a side of the frame lying opposite vapor or hot gas entry, the connections being for the discharge of ex-haust gas-containing vapors.

Abstract: ABSTRACT OF THE DISCLOSURE   An optical multiplexer/demultiplexer comprises an optically trans-missive body having three or more sides.  Interference filters are provided on all but one of the sides and angled spacers are provided to connect optically the filters with collimating lenses.  In the case of the side without a filter a spacer connects that side directly with a collimating lens.  Optical fibers are joined optically to the free ends of the collimating lenses.  When a laser beam containing several wavelengths is passed into the optical fiber which is optically connected to the unfiltered side of the body, the beam passes through the body and a portion having a specific wavelength is transmitted by the first filter it engages the remainder being reflected.  The reflected portion impinges on a second filter which transmits a second wavelength portion and reflects the rest and so on until ultimately all the wavelengths in the beam have been directed to different specific output optical fibers.  The device has a shorter optical path that conventional devices of this type and correspondingly improved insertion loss.

Abstract: FLAME CUTTING MACHINE WITH LOST CUT RE-ESTABLISHMENT              ABSTRACT OF THE DISCLOSURE           A flame cutting machine is provided having a CNC control with a programmable memory wherein the mem-ory is programmed to cause automatic cutting of rows of pieces continuously in succession, and wherein the mem-ory also includes selectively actuatable instructions to prevent the torches disposed at a termination point from automatically proceeding to the next row, but instead to cause the torches to automatically proceed directly to the start-pierce point of the row just completed.  The torch or torches which have properly cut a complete piece are turned off, while the remaining torch or torches which have involved a lost cut are re-activated at the start-pierce point so, as the row cutting cycle is repeated, the previously lost portions will now be cut.  The memory is also programmed to-selectively in-struct the machine to reverse from the cut termination point if desired.

Abstract: Abstract In a jet type printing  system a plurality of ink jets are provided in line in the direction of carriage movement.  The ink jets are deflected to print in a conventional manner and also pass by charging electrodes which charge individual droplets as they are broken off from the jets.  The charging electrodes are provided with a charge to produce scanning transverse to the direction of carriage movement such that if no charge is provided, ink will be caught in a catcher and returned to the ink reservoir for reuse.  By interlining the lines a faster more effective printing occurs.  Interlining may be done in accordance with several stated methods.  An alternative provides ink jets one above the other with deflection means causing deflection to occur in opposite directions so that one effectively scans up and the other scans down, this alternative preferably employing a pair of ink catchers for the respective jets.

Abstract: ABSTRACT Ethanol is produced by carbonylation of methanol by reaction with carbon monoxide in the presence of a carbonylation catalyst to form acetic acid which is then converted to an acetate ester followed by hydrogenolysis of the acetate ester formed to give ethanol or a mixture of ethanol and another alcohol which can be separated by distillation.  Preferably the other alcohol or part of the ethanol recovered from the hydrogenolysis step is recycled for further esterification.  Carbonylation can be effected-using a CO/H2 mixture and hydrogenolysis can similarly be conducted in the presence of carbon monoxide, leading to the possibility of circulating gas between the carbonylation and hydrogenolysis zones with synthesis gas, preferably a 2:1 H2:CO molar mixture being used as make up gas.
