Date Oct. 16, 1980.Disclosed is a method for recovering oil and gas from carbonaceous materials utilizing two molten baths. In the first molten bath reaction vessel, the carbonaceous material is thermally devolatilized. Part of the first melt from the first reaction vessel containing non-volatile constituents is passed to the second molten bath reaction vesel which contains a different melt at a higher temperature. The two melts are only partially soluble in each other so that they can be easily separated. Oxygen, air or oxides are charged to the second reaction vessel for gasifying residual quantities of carbon by oxidation. The first melt is returned to the first reaction vessel from the second reaction vessel. The melt in the first reaction vessel may comprise lead or zinc and be maintained at a temperature of 500 DEG  C., while the melt in the second reaction vessel may comprise raw iron and be maintained at a temperature of 1200 DEG  C.

Abstract: A transmitting section of the system according to the invention has transmitting section signal paths for at least three classes of motion, each with a preprocessing circuit (143, 145 and 147) which are provided with means for individually sampling. These sampling means sample in accordance with separate sampling patterns so that each preprocessing circuit (143, 145 or 147) supplies a video signal which is suitable for a display with an optimum distribution of temporal and/or spatial resolution for the associated class of motion. Dependent on the class of motion determined, one of the preprocessing circuits (143, 145 or 147) is coupled to a channel (170). The video signal to be supplied to the channel (170) is therefore a video signal suitable for a display with an optimum distribution of temporal and/or spatial resolution for the given class of motion (Fig. 1A). A normal-definition MAC receiver is capable of displaying the compatible transmitted video signal, but without being able to make use of the possibility of a display with a higher spatial resolution in the case of little or no motion. A high-definition receiving section of the system according to the invention also has at least three receiving section signal paths comprising a postprocessing circuit (43, 45 and 47) which decodes a received video signal in accordance with a method associated with the relevant postprocessing circuit (43, 45 or 47). The correct postprocessing circuit (43, 45 or 47) is selected in accordance with the class of motion, so that in the receiving section of the system according to the invention a display with an increasing spatial resolution can be achieved in the case of a decreasing motion

Abstract: A process for the liquefaction of natural gas is disclosed wherein expansion valves for low-level multicomponent refrigerant and liquefied gas product streams are replaced with process-loaded turboexpanders (141, 151) having liquid inlet streams. Each turboexpander is coupled with a compressor or pump (142, 152) so that expansion work extracted from a given stream is used directly to compress or pump the stream prior to cooling and expansion. The use of process-loaded turboexpanders reduces the minimum work of liquefaction and increases the liquefaction capacity of the process.

Granted: 1999-02-16
Abstract: A  process  is  dislosed  for  manufacturing  gelatine  foils, especially leaf gelatine,  from powdered gelatine.  According to the invention,  less than 40 wt.% water relative to the entire mass  is  added  to  the powdered  gelatine.  The  mass  is  then plasticized at elevated pressure and temperature while applying shear forces. The plasticized mass is then forced in the form of a foil through a slit nozzle. The foil is withdrawn under tension from the slit nozzle,  and then dried.  The process according to the invention is  considerably less  complicated than the known methods and in particular produces uniform, smooth end products which  can be  further processed by  automatic  means,  and in particular can also-be mechanically packaged.

Granted: 2000-08-01
Abstract: This burner arrangement has a main feed channel (2) for a fuel-air mixture, which channel discharges into a combustion chamber (1). A swirler, which is provided with swirl vanes (5), is penetrated by a burner lance (3), and into which exit openings for the fuel feed discharge, is provided in this main feed channel (2). The aim is to create a burner arrangement in which it is impossible for undesired instances of ignition of the fuel-air mixture to occur outside the combustion chamber (1). This is achieved in that the exit openings are constructed as nozzles (9) which discharge into a region between the swirl vanes (5). In this regard, at least one nozzle is provided between two neighboring swirl vanes (5).

Abstract: A postage meter machine having a stator part and a print rotor.   The motors, a drive, a motor switch, a battery, a logic unit, a clock module, and two position indicators are disposed in the stator part.  A catch-stop actuator, a catch-stop row sequence with three catch stops of different length as well as a date stamp with four counter  wheels  and  coordinated  stop-catch  device  are disposed in the print rotor.   The counter wheels are disposed coaxially next to each other and each exhibits twelve print positions, which are rotatable stepwise by the catch-stop row sequence.  Based on the kind of teeth and the length of the cams, either only one counter wheel or two counter wheels or all three counter wheels are rotated simultaneously by one position in case of one catch-stop row sequence step.   A coupler connects one motor to the catch-stop actuataor in a certain angular setting of the print rotor.   The  logic unit,  initiated by the clock module, controls such motor.  Depending on the date set in each case, this motor runs for such a time until the catch-stop  row  sequence  has  performed  one,  three,  twelve, thirteen, sixteen, or seventeen steps.  In each case, the respective subsequent setting of the day is achieved.

The concrete reinforcement  is  assembled  between  the  sheathing panels at the factory site.  When the formwork module is fully assembled, it is then collapsed, that is, by moving  one  sheathing  panel  against  the  other including  collapsing  the  collapsible  connecting elements and sandwiching the concrete reinforcement which is preferably in the form of a grid,  and the formwork module can then be stored and transported to a building site.  At the building site,  the formwork module is spread apart  to the  full extent  of the connecting elements and spacers are provided between the  sheathing  panels  for  maintaining  the  panels apart.  Typical joint mating means are installed at the edge areas of the sheathing panels to form joints with adjacent panels.
