Title: Manufacture of caramel.
IPC: A23G3/32
Filed: 1970-01-06
Abstract: 1,273,124. Caramel color manufacture. PEPSICO Inc. 9 Jan., 1970 [14 Jan., 1969], No. 1273/70. Heading A2B. Caramel color is prepared by forming a mixture of fruit juice having a sufficient carbohydrate content to caramelize and a caramelization catalyst, heating the mixture under pressure to a caramelization temperature to caramelize the monosaccharide in the fruit juice, removing the fruit flavor components and cooling the resultant color. Prior to the above treatment, the fruit or juice may be hydrolysed to convert its polysaccharide content to monosaccharide. A suitable catalyst is a mixture of ammonium and alkali salts of sulfurous or sulfuric acid. The caramelization may be conducted in the range of 230‹ to 320‹F. Examples describe the above treatments in relation to apple juice, lemon juice, berries and dates, the latter two being subjected to a hydrolysis pretreatment. Further examples describe the preparation of carbonated beverages from caramel color and orange oil or lime and lemon oils.

Title: Loop communication system
IPC: H04M9/02
Filed: 1982-07-19
Abstract: A time division multiplex loop communication system for voice and data is disclosed with multiaccess time slot seizure and data transmission capability from all station nodes without changing the idle, nonreserved, status of the seized time slot. A method and station node apparatus sends bursty data packets from a node when a time slot is not busy serving a longer duration voice telephone call. The apparatus eliminates the need for inefficient time slot request, acknowledgement and reservation procedures which require several TDM frames to complete and which are typically longer in duration than the bursty data packet to be transmitted. All stations have access to all time slots for bursty data transmission under control of loop interface circuitry which statistically ensures the successful data transmission from all sending nodes. The interface circuitry includes input and output buffers, slot and bit identification circuitry, bit stream retard circuitry, output selector circuitry, bypass decision circuitry, and data and voice insertion control circuitry comprising a slot decision control circuit, a seizure timing circuit and an acknowledgment check circuit.
