Abstract: ABSTRACT OF THE DISCLOSURE          In the prior art exemplified by U.S. Patents Numbers 3,393,587, 3,815,451, 3,881,376, 4,261,233 and 4,307,632, difficulty was encountered in depressing the ratchet reversing pin so that it could begin entry along with the control knob stub shaft portion into the control knob bore.  In accordance with the present invention there is provided an assembly access opening disposed so that it is substantially in axial alignment with the central axis of the ratchet reversing pin when the latter is in contact with the bottom surface of the circular depression just prior to its entry into the control knob bore.          Since the ejector pins have been repositioned so as to be out of the way, it is possible to insert a tool via the assembly access opening and conveniently depress the ratchet reversing pin sufficiently to permit its entry into the control knob bore.

Abstract: Abstract of the Disclosure A signal processing apparatus comprises first and second  switches  connected  respectively  to  an  input terminal and an output terminal of the apparatus and defines first and second signal channels extending in parallel from the first switch to the second switch.          The first and second switches are operable to connect a  selected  one  of  the  signal  channels between the input  terminal  and  the  output  terminal.  The  first signal channel includes a signal processor. The input terminal  is  connected to the  signal  processor  even when the second channel is selected for connecting the input terminal to the output terminal so that a signal applied to the input terminal is applied to the signal processor as well as to the output terminal when the second channel is selected. Thus, the signal processor can be  exercised  and the output of the signal pro-cessor can be monitored while the second channel is utilized  for  transmitting  a  signal  from  the  input terminal to the output terminal.

Abstract: Symbiotic genes of Rhizobium bacteria are isolated and identified, for cloning into other cells etc., by a process which involves introducing into the chromosomal DNA of Rhizobium a promoterless lac operon from E. coli. This is accomplished by use of a novel construct of the promoterless lac operon, a transconjugant such as defective mu-d I (kan, lac) phage and a suitable suicide vector such as pGS6. The transconjugant Rhizobia so formed is selected for kanR, to isolate cells which have taken up the lac operon. On a random basis, some of the transconjugants have inserted the lac operon appropriately to a sym gene promoter which now acts as promoter for the lac operon. Now, in the appropriate stimulative environment for the sym gene promoter, the lac Z gene transcription to produce .beta.-galactosidase is initiated instead of the usual sym gene function. The generation of .beta.-galactosidase is readily detected and analysed, so that cells in which the lac operon fraction has entered the sym gene can be identified, cultivated, and their genome DNA analysed to locate the gene.
