Abstract: PROCESS FOR STEAMING COFFEE                    Dennis R. Grubbs Abstract A method for forming a steamed roast and ground coffee having low off-flavor and desirable acidity is disclosed.  A conventional coffee extraction column is heated to a temperature above 212°F and then loaded with roast and ground coffee.  Super-heated steam is passed into the column to develop a pressure of about 100 to about 200 psig within the column, and the coffee is steamed for about 2 to about 15 minutes.  The steamed coffee is extracted in a conventional manner.  The extract from the steamed coffee can be combined with the extract from unsteamed coffee  An advantage of this steaming process is that it creates desirable acidity in soluble coffee extracts without developing undesirable off-flavors.

Abstract: ABSTRACT        Doppler radar sets of the type including circuitry for determining and displaying sense of target motion along the radar beam.  The Doppler phase shifters in the I and Q channels of pulse radars of this type are designed to operate at frequencies much higher than the Doppler baseband frequencies by selecting one of the Doppler sidebands of the radar's pulse repetition frequency, or one of the sidebands of a harmonic of such pulse repetition frequency, for application to said Doppler phase shifters.  The higher operating frequency simplifies the design and construction of the Doppler phase shifters.

The signal within each block remains in its original order.  Preferably, the signal representing one line of video is split into blocks which are reordered within the line time to cause translation or rotation of analogue components.  Alternatively group of lines may be processed as a group to cause reordering of the analogue components between lines.  The preferred arrangement does not split the blocks of analogue signals already present in the MAC signal.  The receiver is arranged to receive inform-ation regarding the encryption technique with the tele-vision signal and to reorder the blocks constituting the received signal whereby to reconstruct the original signal.

Abstract: AN AQUEOUS SLURRY OF A SOLID FUEL AND A PROCESS               FOR THE PRODUCTION THEREOF     Abstract of the Disclosure An aqueous slurry of a solid fuel and a process for producing said slurry are described. The aqueous slurry consists of a highly concentrated slurry of a pulverized, carbonaceous material having a particle size of at most 0.5 mm, and 0.02-2% by weight of at least one additive. The solids content of the slurry is 65-90% by weight, preferably 70-80% by weight. The slurry is characterized in that the additive includes a water-soluble surface active compound which is an ethylene oxide adduct having the following formula:                        RO(CH2CH2O)nH     wherein R is an aliphatic or acyl group with 10 to 24 carbon atoms or a substituted aryl group with 12-54 carbon atoms; and n is at least 40 but less than 100; or n is 40-200 in which latter case the ratio of ethylene oxide units to the number of carbon atoms in the group R is 3.5-6.0 when R is an aliphatic or acyl group and 3.0-5.5 when R is a substituted aryl group. By adding the ethylene oxide adduct after wet milling and dewatering of the carbonaceous material, an aqueous slurry is obtained which is stable, i.e. it does not separate during trans-port and storage, as well as low-viscous, i.e. pumpable at a high solids content. In addition to the specific ethylene oxide adduct which preferably is added in a concentration of 0.05-0.8% by weight. other conventional additives, such as stabilizers, antifoaming agents, pH modifying additives and antimicrobial agents may be added.
