Abstract: ABSTRACT          The presently well-established techniques for down-conversion of microwave signals use heterodyne conversion which relies on mixing a signal from a local oscillator with the micro-wave input signals, microwave varactor  frequency dividers and the use of two GaAs MESFETs in a balanced configuration for sub-harmonic division.  The heterodyne technique limits the instantan-eous bandwidth that can be down-converted, the varactor  divider requires amplifiers to recover the input signal and the use of two MESFETs requires special circuitry on the output to recombine the divided signals from the two drain terminals of individual MESFETs.  The present invention overcomes these problems by providing a microwave frequency divider using a single, dual-gate GaAs FET device to perform parametric division and amplification simultaneously at microwave frequencies.  The FET constitutes a nonlinear reactance that, when energized, transforms the input signal at fo to an output signal at fo/N.

Abstract: Abstract A position indicating system for an elevator system includes a position indicator which operates in conjunction with an elevator control to provide an indi-cation of elevator position and direction of travel by means of a display disposed within the elevator or at any position in the building.  The position of the elevator is sensed by the elevator control and is converted into a multi-bit digital word which is transmitted serially over hoistway wires to the position indicator.  The position indicator utilizes the multi-bit word to access a memory in which is stored a library of codes for  character sets which may be indicated by the display.  The proper codes are obtained from the memory and used to energize the display elements to illuminate the desired characters. By transmitting the position word in serial fashion to the  position  indicator,  only  six  hoistway  wires  are required regardless of the number of position indicators utilized  in  the  building.   Further,  a  standardized library may be stored in the memory element,  in turn permitting the position indicator to be mass produced.

Abstract: METHOD OF AND APPARATUS FOR FORMING AND CARTONING    MULTI-STACK ARRAYS OF COMPRESSIBLE ARTICLES                         ABSTRACT       The apparatus forms multi-stack arrays of compressible, generally flat articles -- for example, elongate catamenial napkins --on a receiving platform disposed adjacent a stack forming apparatus by pushing one stack against the back wall of the receiving plat-form, and then pushing successively formed stacks into adjacent relation with the last stack pushed onto the receiving platform. This is done with a stack pusher, and controlling the lengths of its successive strokes as required. Upon moving each stack into its respective position on the receiving platform, it is individually compressed to reduce the height of the stack to about the height of the carton into which the array is to be loaded as a unit. An array pusher then pushes the array orthogonally with respect to the direction of pushing the stacks onto the receiving platform to displace the array as a unit into a carton through a loading funnel. Preferably, elongate articles such as catamenial napkins are oriented in the associated stacker so that, relative to the length dimension of the articles, the stacks are displaced sideways from the stacker onto the receiving platform so that the stacks are oriented in side-by-side relation with each other. Individual compression of each stack substantially obviates any interleaving or damage of the articles in adjacent stacks which might otherwise occur: particularly at high stack pusher velocities.
