Abstract: PROCESS FOR RECOVERY OF AROMA .                     ABSTRACT       A process for the treatment of an aqueous coffee extract wherein the extract is subjected to concentration by evaporation and the vapors resulting from said concentration are condensed to form an aqueous liquid.  The aqueous liquid is passed through an adsorbent comprised of non-ionogenic macroreticular cross-linked resin particles to adsorb aroma volatiles.     Preferably, the resin is a divinylbenzene polymer and the aroma volatiles are desorbed from the resin particles with steam as the desorbent. The aroma volatiles which are recovered are added to the concentrated extract which may then be dried.

Abstract: ABSTRACT: "Compensation of the 1st-order transfer-efficiency in a C.T.D."           Charge transfer devices exhibit  transfer ineffi-ciencies, so that a part of a transferred charge packet is left and lags the original charge packet. This results in smearing of the original charge packet, thereby ad-versely affecting the unit-function response and the fre-quency response of the charge transfer device. The inven-tion provides a solution to said problem, utilizing a com-pensation charge derived from the original charge packet, which at a suitable instant is applied to a point where the residual charge is cancelled via a feedback loop.

Abstract: PREPARATION OF ALKYLIDENE DIESTERS    ABSTRACT OF THE DISCLOSURE         Alkylidene diesters such as ethylidene diacetate are selectively produced in high yields by reacting an ether and/or an ester under substantially anhydrous con-ditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound, a halogen component, a palladium cocatalyst and a promoter component which is an agent for liberation of carboxylic acid anions.  The process is carried out in the liquid phase in a solvent comprising a carboxylic acid at a temperature in the range of 150 to 190° C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm2 and a carbon monoxide/hydrogen mole ratio of 6:1 to 1:2 for the ester reaction and 10:1 to 1:2 for the ether reaction.  When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.

Abstract: ABSTRACT OF THE DISCLOSURE      A solid form adsorbent of carbon monoxide, that is ob-tained by the process including the following steps.  First, copper salts or copper oxide is stirred in a solvent.  Then, into the solution or suspension thus obtained, active carbon is added.  Finally, the solvent is removed by means of pres-sure reduction, distillation, etc.  The carbon monoxide adsorbent produced according to this invention adsorbs carbon monoxide rapidly when it is brought into contact with a mixed gas.  The adsorbed carbon monoxide can be readily separated and discharged through either heating the carbon monoxide adsorbent to about 60°C or reducing the partial pressure of carbon monoxide.  The carbon monoxide adsorbent obtained in accordance with the present invention is stable relative to the water content in the mixed gas, and it is capable of separating carbon monoxide directly from the mixed gas con-taining the water.  Also, the separated carbon monoxide does not contain the vapor of the solvent from the carbon monoxide adsorbent.  Therefore, it is not necessary to provide equip-ment to collect the solvent vapor.  Furthermore, this carbon monoxide adsorbent does not produce corrosive gases, etc. The carbon monoxide adsorbent obtained by using copper (II) salts or copper (II) oxide is also stable relative to sulfur content in the mixed gas.
