Abstract: ABSTRACT OF THE DISCLOSURE:         An averaging method which eliminates periodic strays and which is usable in analog-digital computers performing an averaging procedure. Such a procedure which processes a set of signals picked up from an examined object elicits an averaged evoked response due to its capability of reducing internal noise and periodic strays originated in an environment comprising a mains supply network pro-portionally to the square root of N sweeps of the procedure, and in the case where the periodic strays and external stimuli are synchronous, the averaged periodic strays are not sufficiently reduced and distort the averaged evoked response making its right interpretation difficult. In order to overcome the latter problem, the averaging method eliminates the periodic strays from the set of signals during the averaging procedure in greater extend i.e. pro-portionally to the number of N sweeps of the averaging procedure resulting in their at least N-fold reduction thanks to introducing permanent desynchronization between the frequency ?  of the external stimuli and the frequency ? of the periodic strays and thanks to introducing an odd number K of half-periods of the frequency ?, which number K determines the value of the period T according to the formula: T = ? t K, where K is a natural and odd integer.

Abstract: FAIL-SAFE SPRING-LOADED HYDRAULIC BRAKE AND CONTROL SYSTEM THEREFOR              Abstract of the Disclosure The horizontally rotatable upper section of a mobile crane is swingable in opposite directions by a speed reducer which is driven by a selectively operable reversible variable speed hydraulic motor.  A fail-safe spring-loaded hydraulic brake located on the speed reducer operates, when needed, to slow or stop or prevent rotation of the upper section.  A hydraulic control system which supplies pressurized hydraulic fluid to operate the motor and the brake includes a pedal-operated master brake cylinder for selectively applying the brake when the motor is in operation.  The brake comprises a cylinder housing, an outer brake piston axially movable through a hole in the housing, and an inner brake piston axially movable in a bore in the outer brake piston.  Each piston has an extended position and a retracted position.  These pistons are movable alternately to extended (brake-apply) position to force a movable brake plate into frictional engagement with a brake disc which is mounted on and rotatable with a motor-driven input shaft of the speed reducer.  A main biasing spring is provided to bias the outer brake piston into extended brake-apply position before the hydraulic motor is turned on and any time a selector valve is opened to dump pressurized fluid from a reservoir.  An auxiliary spring is provided to bias the inner brake position into retracted position.  The hydraulic control system is operable to start the motor and to supply fluid to shift the outer brake piston to retracted brake-release position.  The pedal-operated master brake cylinder is then operable, if needed, to supply fluid to shift the inner brake piston to extended brake-apply position even though the outer brake piston is still retracted.

Abstract: ABSTRACT         A chemical sensor matrix is provided for sensing the presence of chemical agents by chemo-electronic means.  The chemical sensor matrix is comprised of a plurality of resonators embedded in a single monolithic piece of piezoelectric crystal.          The resonators are arranged in rectangular row and column configuration including  m rows and n columns, each of the resonators being separated from its neighboring resonators by distances such that the resonant energies do not overlap.  Each of the resonators is coated with a different chemical substance to be sensitive to a chemical agent to be detected so that when the chemical substance reacts with the chemical agent, the frequency fmn changes.  Each of the rows of resonators bears a metallic electrode stripe for that row, and each of said columns of resonators bears a metallic stripe for that column.  The electrode row stripes are positioned on the top surface of the crystal, and the electrode column stripes are positioned on the bottom surface of the crystal.  The areas of overlap of said row and column stripes are registered with the central portions of the embedded resonator. Two diode arrays are positioned on the periphery of the crystal for addressing the individual row electrode stripes and the individual column electrode stripes so that the desired resonator can be activated by connecting the stripe corresponding to its row address and the stripe corresponding to its column address to suitable active oscillator circuitry and signal processing means.  The resonators fmn can the be interrogated sequentially and frequency change registered.

Abstract: ABSTRACT OF THE DISCLOSURE      An  improved  method  of  making  reconstituted  tobacco using a dry-forming process.  Fiberized tobacco stems and scrap are combined with tobacco material of a fine particle size.    The  resulting tobacco mixture  is conveyed  in an airstream and deposited on a moving foraminous surface.  An adhesive is incorporated into or applied to the web bonding the tobacco particles into a coherent sheet, and the sheet is dried if necessary.  The dried sheet may be divided into leaflets or shredded for further processing as reconstituted tobacco.   In preferred embodiments,  cellulose  fibers  are mixed with the tobacco particles prior to web formation to impart increased sheet strength.   In a further embodiment tobacco fines are mixed with the adhesive and applied to the web in the adhesive composition.  Results obtained by means of the present invention include cost savings particularly in terms of reduced capital costs. Because the tobacco is used substantially in its natural state, the aroma and other desirable tobacco attributes are retained.
