Abstract: UNDERGROUND PIPE DETECTOR Abstract of the Disclosure An apparatus and method wherein an electrical impulse source transmits a radar-type signal through an antenna into the ground and is reflected by a target.  The reflected signal or echo is detected by the antenna and an analog-to-digital converter converts it to a digital form which may be readily operated on, stored and recalled.  A memory stores the information until re-called for comparison with a subsequent signal to give an indica-tion of the location of metallic and non-metallic buried targets.

Abstract: Noise Reduction in Pneumatic Tires Abstract of the Disclosure A pneumatic tire having a tread design for re-ducing the amount of noise generated by the tire when rolled on a given surface, is disclosed.  The tread comprises a plurality of circumferentially spaced lugs defining therebetween respective grooves,  the lugs all being substantially similar to one another in configura-tion.  Each of the lugs and its corresponding groove adjacent thereto in a given circumferential direction together defining a pitch of specified length which circumferentially is dimensionally identical to the pitch of certain others of the lugs and their corres-ponding grooves and is yet dimensionally different from the pitch of still others of the lugs and their corres-ponding grooves.  The lugs are arranged such that certain (though not necessarily all) of the lugs and their corresponding grooves of the same pitch adjoin each other in succession in the form of a pitch-identifiable group differing in pitch from an adjoin-ing pitch-identifiable group of still others of the lugs and their corresponding grooves.  Such groups adjoin each other in a preferred circumferential series to define a pitch sequence which over its circumferential extent has excitation peak frequencies that do not coincide with the resonant frequencies of the tire.        The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention provides an automatic arpeggio apparatus for an electronic musical instrument.  A pulse generator repeatedly generates pulses upon depression of a key which are applied to a timing pulse generator.  A memory circuit generates musical scale digital signals in response to timing pulses obtained from the timing pulse generator and the digital signals are fed to a D-A converter which converts them into analogue signals.  A calculation circuit then adds to or subtracts from these analogue singnals a voltage at a level corresponding to a key depressed and a voltage controlled type oscillator produces an output frequency dependent upon the output voltage of the calculation circuit.  In this manner, depression of a signal key causes the appropriate arpeggio to be generated.

Abstract: ABSTRACT OF THE DISCLOSURE       A two step interfacial polymerization process for encapsulating operative chemically active substances in high quality semipermeable membranes.  An emulsion is formed wherein the discontinuous phase contains the substance to be encapsulated and a first monomer.  When a second monomer is added to the continuous phase, an imperfect membrane forms about the droplets of the discontinuous phase.  Removal of the continuous phase, followed by resuspension of the raw microcapsules and addition of a second portion of second monomer, causes further polymerization strengthening the membranes and "patching" macroporous defects in them.  The choice of solvents and control of reaction conditions, such as pH, maximize the yield of operable labile substance encapsulated.  A method of encapsulating a very high concentration of hemoglobin is also disclosed.  Adaption of the two step process provides a method for forming and controlling the pore sizes in the membranes of a number of known prior art encapsula-tion processes.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for providing a compound liquid jet of fine droplets, particularly suitable for ink-jet recording systems.  A primary stream is formed by ejecting under pressure a primary liquid form a nozzle and then causing the primary stream to traverse a thin layer of a secondary fluid to form a compound liquid stream which breaks up to form a compound jet of fine droplets each containing both the primary liquid and the secondary fluid.  since only the primary liquid passes through the nozzle, it may be chosen to minimize, or even eliminate, nozzle clogging and other difficulties associated with the use of most inks in ink-jet systems.  The secondary fluid may contain fine particu-late material, e.g., pigments, and it is used to contribute color or other physical properties to the compound jet.

The bowls vary in capacity from each other.  The handles of the spoons are releasably affixed to a spoon holding ring by a slot at the end of the handle.  Each slot has an arcuate section so that a tubular spoon hold-ing ring can be snapped into the slot due to flecture of the spoon handle portions defining the slot.  The slots permit the spoons to be individually pivoted on the spoon holder ring  or individual spoons can be removed from the spoon holder ring. The spoons nest together to form a compact unit.  The spoon holder ring is designed to permit the entire assembly to be hung up in the kitchen in a convenient location. Each spoon is clearly marked with an indication as to its bowl capacity.          Several of the spoons have a measuring ledge within the bowl and these spoons can be used to measure two different capacities depending on whether the spoon is filled to the ledge or to the top.  Also  spilling from these spoons is minimized if the spoon is filled only to the ledge.

Abstract: ABSTRACT         A companded digital delta modulator which can encode both voice and voice band modem signals over a wide range of input levels is shown.  The companding method or algorithm is based on measuring bit stream correlation and can be scaled to give substantially maximum performance over a wide range of signal tones.  The algorithm has a low sensitivity to digital channel errors, thus making it suitable for signal coding for satellite channels and the like.  In addition, the digital design permits common hard-ware to simultaneously serve a large number of lines, thus permitting the substantial savings in the hardware cost per line.  A further aspect of the invention concerns the ability to handle multiple bit delta modulation as well ?s single bit delta bit modulation in the above environment.
