Abstract: APPARATUS AND METHOD FOR FABRIC CLEANING WITH FOAM      ABSTRACT           An apparatus and method, particularly adapted to clean fabrics, is disclosed.  The apparatus includes a generally hollow head having two foam mixing chambers in close proximity to a vacuum chamber.  Foam is gen-erated adjacent the fabric to be cleaned by admixing pressurized air and a liquid foam-producing agent in the two mixing chambers.  The air pressure directs the foam from the second mixing chamber towards the fabric. Two screens are used to control the consistency and application of the foam.  Suction is simultaneously provided in the vacuum chamber, so that the foam is rapidly and continuously recovered.  A brush means is positioned between the second mixing chamber and the vacuum chamber to further agitate the foam and fabric to be cleaned, and to help create a partial pressure when the moving foam is applied to the surface of a fabric.

Abstract: ABSTRACT       IMPROVED ADDRESSING FOR A MULTIPOINT COMMUNICATION SYSTEM FOR PATIENT MONITORING       A method for dynamically assigning addresses to new module  as they are coupled to a communication system with a synchronous data link control (SDLC) bus is described.  These modules communicate with a display unit via the SDLC bus. The SDLC bus is controlled by a primary station in the display unit, with all modules acting as secondary stations.  The primary station periodically broadcasts a time-tag to all modules at a thirty-two hertz rate.  At power up, each module obtains a number, module 16, derived from the lower four bits of its unique twenty-four bit serial number.  The module uses this number as a count of the number of time-tags which must occur before the module responds to the primary with an address request.  If there are no collisions with other modules, the primary sends the module a packet which assigns the module the next available address.  In the event of a collision (i.e., two or more modules request an address at the same time), the primary SDLC controller detects a CRC error and ignores the SDLC frame.  The modules will each time-out and obtain a new number, modulo 16, derived from the next significant four bits of the module serial number.  This process continues until the module obtains an address.

Abstract: CLOSED LOOP ALL FIBER OPTIC GYROSCOPE WITH DIFFERENTIAL FREQUENCY PROPAGATION        Abstract of the Disclosure A gyroscope  system includes a coherent  light source that  supplies  counterpropagating  waves  to  a sensing loop through a pair of directional couplers.  The polarizations of the waves are controlled so that they traverse identical paths before recombining in one of the couplers to form an interference pattern.  Rotation of the sensing loop,  a phase modulator and a frequency shifter cause phase changes in the counter propagating waves.  A detector monitors the interference pattern of the combined waves and provides a signal to the coherent demodulator that controls the phase modulator.   The output of the coherent demodulator is input to a servo loop circuit that drives a voltage controlled oscillator. The output of the voltage controlled oscillator is an oscillatory signal having a frequency equal to the shift in  frequency  that  the  counter  propagating  waves experience in traversing the frequency  shifter.  The feedback circuitry adjusts the frequency shift to null the phase  difference  between  the  counterpropagating waves.  The frequency shift is linearly related to the frequency  of  the  signal output  from  the  voltage controlled oscillator.  Each cycle of the output of the voltage controlled oscillator corresponds to a fixed angular increment of displacement of the sensing loop. The rotation rate of the sensing loop is a function of the frequency shift and transit time of the waves through the sensing loop.   The gyroscope  system  determines rotation rates and angular displacements over a wide dynamic  range  by measuring the  frequency  and  zero crossings  of the  oscillatory output  of the  voltage controlled oscillator.
