Abstract: ADSORPTION DECAFFEINATION                           ABSTRACT      The object of the invention is to provide an improved method for removing caffeine from aqueous solutions such as coffee and tea extracts.     Decaffeination with non-solvent systems employing solid absorbents have not been commercially practical because they are either too non-selective or too expensive.     The process disclosed herein decaffeinates an aqueous caffeine solution by contacting it with a a solid caffeine adsorbent which is made more selective to caffeine by a thin layer of a water-immiscible, caffeine-specific solvent.  The caffeine is selectively extracted from the aqueous solution, leaving the solubles necessary for a good tasting beverage, by the solid adsorbent.  Because the solvent is selective, the coated adsorbent likewise shows selectivity.

Abstract: TITLE OF THE INVENTION "PACKAGING PROCESS AND APPARATUS"                 ABSTRACT OF THE DISCLOSURE          A vacuumising and sealing operation on a package comprises initially reducing the external pressure on the package, before sealing of the package, to a value at which the flexible film covering of the package is capable of ballooning, and ensuring heating of the flexible film of the package, preferably while an intermediate pressure is maintained (at which intermediate pressure ballooning could just be sustained without excessive evacuation to reduce the thermal capacity of the circulating air).  Finally the pressure inside and outside is reduced still further before re-pressurising.

Abstract: Abstract DIGITAL ADAPTIVE FINITE IMPULSE RESPONSE FILTER WITH LARGE FIBER OF COEFFICIENTS     A digital adaptive finite impulse response (AFIR) filter having a large number of coefficients is com-posed of two or more separate filter units.  The first filter unit computes response samples ho + hn+1 in response to input signal samples to provide a partial estimated response during each sampling period.  After the signal samples are fully processed by the first unit,  they are  transferred to a second filter unit which  produces  response  samples hn+2  -  hp+1  in response thereto to provide a second partial response. The sum of the two partial responses is computed to provide the total estimated system response.  The two independent filter units thus act simultaneously to provide twice as many coefficients as prior art AFIR filters in the same amount of time.

Abstract: ABSTRACT OF THE DISCLOSURE           A semicontinuous casting apparatus comprises a holding furnace connected through a closed metal feeding system to a metal supply means having a metal supply duct.  Mounted on the metal supply means is a mould provided with a cooling system and having a dummy bar placed in its upper part and connected with a casting withdrawal system.  The mould cooling system is provided with a device for forcing out a liquid coolant from the mould by means of compressed gas. The dummy bar has a central head which accom-modates a heating element and an adjustable valve for admitting an inert gas into the casting being formed.  The casting withdrawal system has two casting withdrawal mechanisms alternately co-operating with the dummy bar and of which one is used for pulling out the casting from the mould for a distance not smaller than the length of the casting minus the length of the mould, and the other one is effective to pull  out the casting from the mould for a distance not smaller than the length of the mould.  The invention is preferably utilized in the production of solid and hollow castings by a semicontinuous casting process in which such castings are drawn up from a mould.

Abstract: POWER AMPLIFIER CAPABLE OF SIMULTANEOUS                  OPERATION IN TWO CLASSES            ABSTRACT OF THE DISCLOSURE   An electronic amplifying apparatus intended for sound reproduction and for music instrument amplification wherein two parallel amplifiers, working simultaneously, each in a different class of operation, are fed from a single driver or signal source and whose outputs are combined.  In the preferred embodiment at least two pairs of push-pull vacuum tubes are required and they are arranged so that one pair operates Triode Class A while the other pair (or pairs) operates Pentode Class AB          (or Class B).  The circuit can then be optimized so that the desirable sonic characteristics of Class A Triode operation are imparted into the Class AB (or Class B) Pentodes which actually produce all or nearly all of the power.  The output power waveform has the high power and efficiency typical of Class AB (or Class B) Pentode operation but without the detrimental sonic side effects, namely, there is the complete absence of crossover or "notch" distortion, and there is a "soft" gradual onset of clip.  Both of these traits are highly desirable and characteristic of the notoriously inefficient Class A          Triode operation.  On/Off switching of various pairs of output tubes may further be employed to add flexibility to the system with regard to power availability and sonic performance.  Single ended configurations as well as solid state devices or hybrid combinations could be arranged to operate in simultaneous different classes of operation and enjoy its attendent benefits.

Abstract: Ribbed Electrode Substrates Abstract A ribbed substrate for an electrochemical cell electrode is made from a mixture of carbon fibers and carbonizable resin and has a mean pore size in the ribs which is 60-75% of the mean pore size of the web portions of the substrate which interconnect the ribs.  Preferably the mean pore size of the web portion is 25-45 microns, and, if the substrate includes edge seals parallel to the ribs, the edge seals preferably have a mean pore size no greater than about ten microns.  Most preferably the sub-strate has the same ratio of carbon fibers to polymeric carbon in all areas, including the ribs, webs, and edge seals.  A substrate according to the present invention will have better overall performance than prior art sub-strates and minimizes the substrate thickness required for the substrate to perform all its functions well.

Abstract: ABSTRACT         In order to produce butt joints between two thin-walled sheet-metal tube sections (22), a one-piece flanged ring (10) is used, which substantially comprises only a securing flange (12) protruding approximately radially outward, an arm (14) projecting from the inner end of the securing flange and a ring land (18) bent obliquely outward toward the securing flange (12) by the arm (14).  The outer diameter of the ring land (18) is selected such that when it is driven into the end of the tube, it comes under pre-stressing and thus pro-duces a stable joint between the flanged ring (10) and the tube (22). The invention also encompasses a simple method for producing the flanged ring (10), in which an elongated, flat sheet-metal strip is first folded and then is bent into annular form, and further encompasses a butt joint, having two flanged rings (10) according to the invention, between two thin-walled sheet-metal tube sections (22).  Finally, the invention also relates to a reliable fixation of the ends of the flanged ring against one another by means of a clamp (11) which can be mounted onto them.          Fig. 2.
