Abstract: ABSTRACT      A method for producing sweetened, sliced fruit or vegetable products by exposing only one surface of the slices to an aqueous solution containing a carbohydrate, an anti-browning agent, and an acid.  The acidity of the finished product may be adjusted so that products appealing to sweet-loving palates or tart-loving palates may be easily produced.  The aqueous solution may advantageously be sprayed on the upper surface of the sliced fruit or vegetable, rather than by soaking or steeping the slices, so that the slices maintain their structural integrity and the application of the solution is not a rate-limiting factor.

Abstract: ABSTRACT:           The invention relates to a method of two-way radiocommunication between fixed stations and mobile stations permitting effective utilization of available radiocommunication channels.  All the fixed stations transmit in a first radio path of multiplexed communi-cation channels and all the mobile stations transmit in a second radio path of multiplexed communication channels, each pair of communication channels in the first and second paths being capable of handling two-way communi-cation between any one of the fixed stations and any one of the mobile stations.  As a result, the known motion of cellular patterning, and in particular the distribution of frequencies or time intervals between cells, is no longer implemented in the invention, at least as regards the routing of communications.  Nevertheless, this notion is retained for exploiting a channel called a semaphore channel serving the procedure of establishing links.  When the channels are time-division multiplexed, in accordance with the TDMA-type method, only two numerical paths are utilized.  When the channels are frequency-division multiplexed, in accordance with the FDMA-type method, only two frequency bands are allocated to radiocommunicatons.
