Abstract: ABSTRACT OF THE DISCLOSURE         A light source coupled to a first fiber optic wave-guide which is coupled by a first directional coupler and a second directional coupler to a second waveguide.  The first waveguide has a phase modulator, a delay loop and a polarization controller therein to cause a differential delay time T on counterpropagating coherent light waves phase modulated at a frequency 1M.  The first directional coupler has one part connected to a photodector and the second directional coupler has a probe coupled to the first fiber and the second fiber.  The probe directs light toward a surface whereupon the counterpropagating waves are shifted in phase by an amount proportional to the amplitude of displacement of the surface.

Abstract: METHOD OF REPAIRING HOT REFRACTORY            BRICK WALLS               ABSTRACT OF THE DISCLOSURE         A high temperature refractory brick wall is repaired by removing and replacing damaged brick while the wall is maintained at a temperature below normal operating temperature but sufficiently high to avoid damage from contraction resulting from cooling.  New brick having a coefficient of thermal expansion compatible with -the heated wall are used to avoid cracking of the wall due to expansion during heat-up.  Workers wearing protective clothing, preferably incorporating a circulating fluid cooling system, remove the damaged brick and install new brick in their place in walls having surface temperatures of about 500° F. or higher and internal temperatures substantially above 500° F., preferably at least about 1500° F.

Abstract: ABSTRACT            A wheeled suction cleaner with endless tracks is driven by a turbine actuated by water flowing through the cleaner.  To enable the cleaner to be steered, the turbine also drives an eccentric mass which momentarily lessens the adhesion of the cleaner to the surface on which it works. Steering is effected by a motor also driven by water flowing through the device which intermittently and at intervals turns a spigot on the cleaner which is connected to a flexible suction hose.

Abstract: Method and Apparatus for Indicating an Operating Characteristic of an Internal Combustion Engine Abstract A method and apparatus are provided for indi-cating an operating characteristic of a periodically combusting internal combustion engine, such as a diesel engine, having exhaust gas issuing from one or more combustion chambers in a periodic manner through a duct.  The particulate in the exhaust gas stream are electrically charged and of the same polarity, and are grouped in packets associated with the periodic combustion in the respective chambers. An electrically conductive, passive electrode, preferably annular in shape, is disposed such that most or all of the exhaust gas flows therethrough so as to electrostatically sense, principally by in-duced image charge, the passage of the respective packets of charged particles.  The electrode is electrically isolated from the duct.  Circuitry with the probe converts the sensed induced image charge to a signal containing a series of pulsating com-ponents corresponding in time with the respective particle packets and corresponding quantitatively with the charge-quantity of the respective particle packets.  An indicating device responds to the pul-sating signal and provides an indication of an operating characteristic of the engine, The electrode is preferably of short axial ex-tent relative to the packet interval to enhance resolution.  Structure and circuitry may be provided to minimize soot deposition and/or leakage currents across an insulator between the electrode and duct.     In one instance, the indicating device may respond to the root mean square of the pulsating signal to provide a quantitative indication of the level of particulate in the exhaust gas stream.  In another instance, the successive pulsations of the signal waveform may be displayed to afford evaluation of the performance of the respective combustion chambers and/or injectors.

Abstract: ABSTRACT         A device (10) for dispensing air-treating vapors having two support members (12, 14) between which is a flexible, generally flat dispensing pouch (18).          The pouch has an inner storage container (46) of an air-treating composition (48) which is burstable by applying sandwiching pressure on the dispensing pouch through the support members to release the composition for dispensing.  The support members have facing, substantially parallel apertured support surfaces (20, 22) which engage the pouch (18) and are relatively movable between a first spacing in which the storage container (46) is protected from bursting and a second spacing allowing bursting of the pouch.  A spacer (16) interconnecting one pair (27) of aligned edges (28-30) of the support members (12, 14) may be removed to allow bursting, and the aligned edges preferably thereafter reconnected at a closer spacing to hold the released composition (48) in contact with much of the inner surface of the dispensing pouch (18).

Abstract: ABSTRACT OF THE DISCLOSURE     A process for converting raw poultry litter to an essentially odor-free product of increased digestibility to ruminant animals includes the steps of reacting the raw litter with acid at a pH of no greater than about 2.5 to thereby stabilize the volatile or potentially volatile nitrogen compounds in the litter and thereafter reacting the acidified litter with ammonia to raise the pH thereof to no greater than about 5.5 to enhance the crude protein content and at some point in the process raising the temperature of the litter to at least 160°F to reduce pathogens to safe levels.  The acidification and ammoniation steps can be carried out in a rotating drum in which the treatments are carried out on the poultry litter in a free-flowing condition.  Heat generated during the ammoniation step can be used to drive off water vapor.

Abstract: Abstract of the Disclosure A frequency converter generates a multiphase alternating current of variable frequency which current feeds an alternating-current machine via alternating-current lines into which for each alternating current phase line one commutating choke is integrated for limiting the change of current with respect to time di/dt.  Since the efficiency of the synchronous motor is best when fed with a sinusoidal alternating current, a frequency-variable filter is provided as a bypass circuit to the synchronous motor which makes the alter-nating current sinusoidal within a predeterminable frequency range.  The frequency of the alternating cur-rent is measured with a frequency meter and monitored for exceeding a limit in a frequency limit detector. The filter can be tuned step-by-step by means of switching signals to different frequencies by changing the inductance or capacitance of series-tuned circuits step-by-step. Undesirable harmonic frequencies can thus be attenuated within a relatively large frequency range.
