Abstract: 19                  47,635-I A B S T R A C T          CONTROL SYSTEM FOR A MULTI-CAPACITY    REFRIGERANT MOTOR-COMPRESSOR            The invention relates to a control system for a multi-capacity refrigerant motor-compressor.      The  system  comprises  control  means  (74,  76, 82-82a, 84-84a, 80-80a, 92-92a,b) for effecting compressor operation in a low capacity mode in response to served-space sensed temperatures differing from a given served-space demand temperature up to a predetermined degree, and in a high capacity mode in response to served-space sensed temperatures  differing  from  said demand  temperature by more than said predetermined degree, and ambient tempera-ture responsive means  (96,96a)  preventing a shifting of the compressor operation from the high capacity mode to the low capacity mode in response to sensed ambient tem-peratures differing from the given demand temperature by more than a predetermined number of degrees.  Preferably, the  system includes timing means  (80)  for delaying re-starting  of  the  compressor  motor  upon  each change  of capacity modes.           The control system fairly matches the compressor capacity to prevailing demand and temperature conditions, and is particularly suitable for use with heat pumps.

Abstract: 21                  48,560 ABSTRACT OF THE DISCLOSURE Protected  liquid-filled  electrical  inductive apparatus having a dry well fuse assembly which includes a dry well fuse holder sealingly disposed through an opening in  the  associated  metallic  casing,  separate  from  the electrical bushings, and a removable fuse portion.  Ioni-zation of the air within the fuse holder is prevented by a resilient  plug  mounted  on  the  removable  fuse  portion which, when the fuse portion is assembled within the dry well fuse holder,  is immediately adjacent to the elec-trical terminal which is closest to the grounded casing. The resilient plug member provides an air seal adjacent to the terminal without providing a pressure seal within the receptacle.

Abstract: ECHO CANCELLATION IN TWO-WIRE FULL-DUPLEX DATA TRANSMISSION WITH ESTIMATION OF FAR-END DATA COMPONENTS         Abstract of the Disclosure A full-duplex, two-wire Nyquist sampled data communication system includes an adaptive echo canceller at each terminal    The echo canceller generates a replica of the echo component of each sample of the incoming signal. The replica and the sample are subtractively combined to provide an echo compensated signal.  During intervals of simultaneous transmission and reception, i.e., double talk, the echo compensated signal may contain not only an uncancelled echo component but also a far-end data component.  An adaptation error signal generator, operating in response to a stream of recovered data symbols, estimates and removes the far-end data component from the echo compensated signal and, in response to the difference, generates an adaptation error signal.  This signal is applied as an error signal to the echo canceller.  This allows the echo canceller to adapt its set of tap coefficients in response to the uncancelled echo component present in the echo compensated signal.  Thus, stable and accurate echo cancellation results even during a double-talk interval.

Abstract: ABSTRACT OF THE DISCLOSURE     A postage meter for use in a remote meter resetting system has data entered by a user of a selected, variable amount of postage in preparation for funding the postage meter with that amount.  A unique combination is generated by the meter which varies as they function of signals generated within the postage meter and of the selected, variable postage amount entered into the postage meter.          The meter also generates a unique user accessible authorization code which is employed by the user when communications are established with a remotely located data center.  The unique authorization code is dependent upon the number of times the meter has been reset and on the other conditions within the meter.  The data center computes and provides to the user a combination to be entered into the meter.  The externally generated combination received from the data center is entered by a user into the postage meter.  The meter generated combination and externally generated combinations are compared within the meter.  When a comparison indicates the existence of a predetermined relationship, the postage meter is funded with the selected variable amount.  Upon funding the meter, a new unique authorization code is generated for subsequently accessing the data center.
