Abstract: WATER-COMPATIBLE REDUCIBLE COMPOUNDS AND THEIR USE       IN ANALYTICAL COMPOSITIONS AND METHODS       Abstract of the Disclosure Certain water-compatible reducible compounds are useful in analytical compositions and elements for assay of various analytes, e.g. microorganisms. These compounds comprise a moiety which provides a detectable species (e.g. a dye) when released from the compound at physiological pH.  Further, these compounds are aromatic derivatives or quinones having water-compatibilizing substituents which allow them to be used in compositions without the use of surfactants.

Abstract: METHOD AND APPARATUS FOR WATERPROOFING                CONCRETE     ABSTRACT OF THE DISCLOSURE:          A  rod  hole plugging system for providing an  effective permanent  plug within a tie rod hole extending  through the thickness of a poured cement wall utilizes a  short, low  cost plug selected from natural fibre or  synthetic foam,  which is soaked by a liquid  resin coating  which is   seasonally   selectible   to   meet   environmental conditions.  The  selected plug has a diameter exceeding that of the rod hole to be plugged.  The selected  group of  resins is water-tolerating and impermeable,  and may be  a  high solids polyisocyanate prepolymer  that  will harden  to  a  polyurethane polymer;  or  it  may  be  a selected  mixture of epoxy resin and hardener.  The plug is  soaked  in the resin,  and  is   then  diametrically compressed and  inserted  within  the  interior  (i.e., inside  the foundation of the structure) end of the  rod hole  being  treated.  The  elastic memory of  the  plug material causes it to swell and engage the walls of  the rod hole, in which condition the liquid resin sets up. A low cost,  substantially waterproof,  permanent plug for the rod hole is thereby established.

Abstract: ELECTRODE FOR CHARGING AND/OR DEFLECTING   FLUID DROPLETS IN FLUID-JET MARKING APPARATUS     ABSTRACT OF THE DISCLOSURE             An electrode for use in a fluid jet marking apparatus includes a flexible and tensionable electrode member mounted in confronting, substantially parallel alignment to a linear array of fluid droplet streams. The mounting of the flexible and tensionable electrode member is accomplished by a pair of mounting arms in spaced-apart relationship, one of the arms being pivotal while the other arm is immovable. The one pivotal arm is thus displaced relative to the other immovable arm so as to responsively tension the electrode member therebetween.            In order to increase the vibrational frequency of the flexible and tensionable electrode member and/or to substantially decrease the vibrational amplitude thereof, at least one intermediate arm having a terminal end in operative contact with the electrode member is provided. The contact of the terminal end of the intermediate arm occurs at at least one location along the electrode member between the pair of spaced-apart mounting arm members and thus essentially shortens the "free length" of the electrode member so that vibrational frequency of the electrode member is substantially increased thereby responsively substantially decreasing the vibrational amplitude of the electrode member towards and away from the droplet streams. In such a manner, the electrode member can be closely positioned laterally of the droplet streams.

Title: Composition and method for metal surface refinement
Inventor: ZOBBI ROBERT G
IPC: C25D5/34
Filed: 1987-02-03
Granted: 1991-06-11
Abstract: ABSTRACT OF THE DISCLOSURE    A  composition for use in the mass finishing of metal surfaces of objects, normally in a vibratory finishing process, utilizes the combination of oxalic acid,  sodium nitrate, and hydrogen peroxide.  The maximum concentration of the latter is limited to a value at which excessive dissolution of metal and pitting of the surface are avoided while, at the same time, cooperating with the nitrate to effect a substantial increase in the processing rate.  Highly refined surfaces are achieved with the process in relatively short periods of time.

Abstract: ABSTRACT    TACHO SIGNAL PROCESSING     This invention  relates  to  apparatus  for  producing a   periodic   output  signal  having  a predetermined period ratio ? relative to a periodic input signal.     Signals from a tachometer on a gearbox are received by a  counter  timer  unit(11),  the  counter  timer unit evaluates the number of clock  pulses k° received from a clock(10) within each period of the tacho signal.  A control  unit receives  values of k°  from the counter timer and employs an algorithm based on the  following equation  to  calculate  a  count value n°to be loaded into a register(30) for the next tacho period. n° =           +    where dK represents k-1  - k° .     An accumulator(17) is connected via  an  adder(31)  to the  register(30)  and  at receipt of each clock pulse from  the  clock(10)  adds   the   count   stored   in register(30)  into  the accumulator(17).  An output is produced  on   line(34)   when   the   accumulator(17) overflows.

Abstract: ABSTRACT OF THE DISCLOSURE.         To move a plurality of interconnected segments which a zig-zag, accordeon or bellows pleat arrangement on or between which sheet elements  such as projecting elements from a  folded sheet are located along a transport path and to permit, selectively, expansion or compression   of the segments for handling of sheet elements, and compact storage, an endless belt, preferably a gear belt sprocket chain or the like, is provided engageable with the segments.  Preferably, lifting rollers are provided, selectively engageable with the belt to slightly raise the segments from transport rails, and decrease friction of the segments with respect to the rails.  The segments can be stored, when empty or loaded, when collapsed against each other, and spread apart for sheet material handling. A plurality of such system can be located or adjacent each other, so that, when the segments are spread apart, suitable mixing or insertion steps can be carried out.  To permit a space-saving arrangement, the transport path can be sinuous,with 180° rotating elements, having carrying rods  engaging    the segments coupled to a disk, turning the segments about an arcuate path defined by the travel of the carrying rods on the disk.  The The segments can be raised, again, by placing a cam track adjacent the disk, on which the carrying rods can run off by means of cam follower rollers.

Title: Adaptive echo canceller with sparse dynamically positioned taps
Inventor: MILLER JERRY A
IPC: H04B3/23

Granted: 1991-02-19
Abstract: ABSTRACT   This invention relates to an echo canceller, for a transmission line, including a shift register having an input for receiving an input signal from a signal source and having a plurality of output taps for providing a plurality of equally spaced delayed signals. A tap coefficient storage memory stores a plurality of tap coefficients. A multiplier multiplies certain of the delayed signals by certain tap coefficients to produce multiplier outputs. A tap allocation circuit determines, on a tap by tap basis, how many and which of the taps are to be turned ON so that its corresponding tap coefficients are multiplied by the multiplier. A subtracter cancels echoes by subtracting the multiplier outputs from signals received on the transmission line. Taps which are turned OFF may be assigned a status of STANDBY and these taps may be activated to compensate for changes in the characteristics of the transmission line.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical information recording disk and optical information recording disk apparatus which increase the recording capacity of data recorded on the disk, and are capable of fast recording and reproduction.  Logical tracks are arranged by sequentially merging physical tracks start-ing at the inner portion of the disk and physical tracks starting at the outer portion, and the number of sectors on corresponding tracks recorded at a constant linear density is invariably constant on the basis of the relation of arithmetical series.  Consequently, the inventive system, despite of the MCAV system of constant disk speed, achieves track access and fast data transfer comparable with the conventional CAV system.
