    摘要： A selected one of a plurality of unique N-bit digital code words that corresponds to an associated signaling message is continuously transmitted until it is desired to transmit a different signaling message. Decoder logic in the receiver looks at a new group of N-signaling bits during each signaling bit interval, without reference to the start of a transmitted code word, and makes a decision during each signaling bit interval as to what signaling message was transmitted. In this manner a keep-alive signal is virtually continuously provided in the receiver. Latch circuitry repeats the previous decision from the decoder logic when the current group of N-signaling bits does not correspond to one of the unique code words or an ordered permutation thereof. In an alternate embodiment a memory circuit requires that the decoder logic repeat the same decision as to what signaling message was transmitted for P consecutive groups of N-signaling bits (i.e., for P consecutive signaling bit intervals) before the latch circuit will indicate that a different signaling message is being transmitted.

    摘要： (17R)-Spiro-[androstane-17,1'-cyclobutan]-2'-ones are prepared by the reaction of a 17-oxo androstane, wherein all other ketones are blocked, with a cyclopropylarylsulfide or with a cyclopropylarylsulfonium salt having a non-nucleophilic anion, in an organic solvent together with a strong base, followed by reaction in situ of the intermediate thereby formed with aqueous acid or water.Some (17R)-spiro-[androstan-17,1'-cyclobutan]-2'-ones are useful as intermediates in preparing (17R)-spiro-[3-oxo-4-androstene-17,1'-cyclobutan]-2'-ones which are aldosterone antagonists. Additionally, (17R)-spiro-[androstane-17,1'-cyclobutan]-2'-ones are useful as intermediates in preparing known 17.alpha.-pregnane-21,17.beta.-carbolactones, valuable aldosterone blocking agents.
