Abstract: CHIPLESS SHELL CUTTER FOR LARGE DIAMETER PLASTIC PIPE     ABSTRACT OF THE DISCLOSURE         A rotatable shell cutter member for cutting a hole in large diameter and thick wall plastic pipe.  The shell cutter member is rotated and advanced with a positive predetermined lead against the plastic pipe and it first forms a hole in the plastic pipe by cutting and retaining a coupon therefrom and it further progressively enlarges the hole to a diameter equal to or slightly greater than the overall outside diameter of the shell cutter member.  The chips initially cut from the plastic pipe in cutting the coupon are discharged upwardly and inwardly of the shell cutter member above the coupon being cut and, when the shell cutter member with its cutting edge in constant cut-ting engagement with the pipe begins cutting a continuous chip cut, it is also discharged upwardly and inwardly of the shell cutter member.  The cutter blade for cutting the plastic pipe is detachably secured to the body member of the shell cutter member so that it may be easily removed and replaced or resharpened and cleaned when the situation requires such action.  A drilling ma-chine powered by a compressed air motor, electric motor or gaso-line powered engine may be used to rotate and advance the shell cutter member although hand operated drilling machines with pos-itive feed advance may also be used.

Abstract: DRY REPLENISHMENT OF ELECTROLESS PLATING SOLUTIONS   Abstract of the Disclosure This invention is for replenishment of an aqueous electroless plating solution using replenishers essentially free of diluents without decomposing the plating solution.  Typical replenisher formulations comprise a combination of a source of metal ions such as cupric sulphate for copper plating solutions and a stabilizer, the stabilizer being in a concentration sufficient to over-stabilize the solution in the immediate vicinity of the plating solution where the replenisher is added, but insufficient, in combination with residual solution stabilizers, to poison the plating solution when thoroughly admixed therewith.  Other addi-tives in the replenisher formulation may include complexing agent-brighteners, surfactants and the like.  Essentially diluent free replenisher formulations are preferred for replenishment rather than aqueous solutions, as in the prior art, to prevent volume growth.

Abstract: Abstract of the Disclosure There is provided a document handler useful in a copying machine.  The document handler is of a type in which sheets are moved in sequence automatically into a registered position on a work surface and then out of that position to make way for the next sheet. The document handler includes a drive surface that is engage-able with a sheet and means to automatically vary the frictional engagement between the drive surface and sheet. This may be achieved by a movable baffle which overlies the sheet receiving surface and includes an idler roller arrangement journaled in a mounting and supported from the baffle.  When the baffle is raised the roller arrange-ment applies pressure to the drive surface in order that a document may be driven toward a copying area and when the baffle is lowered the pressure is released so that the document can be reversed in movement for registration.

Abstract: CATHODIC PROTECTION SYSTEM FOR A MOTOR VEHICLE     Abstract An improved impressed current cathodic corrosion protection system for a motor vehicle having metallic parts to be protected against corrosion in the presence of conden-sation, road splash and high humidity conditions includes a direct current power source and means electrically connecting the negative pole of the power source to the metallic parts of the vehicle.  An electrically insulating, hydrophilic, corrosion barrier coating is formed on the metallic parts of the vehicle to be protected and an electrode of electrochemically inert material is mounted in closely spaced electrically insulated relation to the metallic parts of the vehicle in a location to be electrolytically coupled to any metallic parts of the vehicle exposed through the coating by an electrolyte which forms on the hydrophilic coating as a result of wetting of the coating by any condensation, road splash or high humidity conditions, the elec-trode being electrically connected to the positive pole of the power source.  The electrically insulating, hydrophilic nature of the corrosion barrier coating and the location of the electrode relative to the coating cooperate to permit large metallic areas of the vehicle to be cathodically protected with a single anode even when only limited condensation or road splash or the like occurs and cooperate to reduce power consumption of the system to the level necessary to protect only those metallic parts of the vehicle exposed through the coating, thereby to adapt the system to the power supply capabilities of motor vehicles.

Abstract: ABSTRACT OF THE DISCLOSURE         Novel thermoplastic polyamide blends are provided herein.  The blends are provided by blending high molecular weight polyamides with 0.01 to 20% by weight of a particularly specified polyamide derived from high molecular weight dibasic acids.  For example, one such polyamide may be ob-tained from the reaction of a high molecular weight aliphatic or cyclco-alphatic dibasic acid having from 18 to 52 carbon atoms and up to 30 weight percent, based on the total dibasic acid charge, of a short-chain, saturated aliphatic dibasic acid having from 2 to 13 carbon atoms with a stoichiometric amount of an aliphatic saturated diamine having from 2 to 10 carbon atoms or with a mixture of such diamines.  By this blending step, the flow characteristics and rheological properties of high molecular weight thermoplastic polyamides are significantly improved.  This enables the poly-amide resin to be more effectively and efficiently extruded, molded, milled or otherwise processed.  The composition also has improved flexibility flexural strength and impact resistance.

Abstract: 60.436 SPECIFICATION                  ABSTRACT OF THE DISCLOSURE     A method of determining the flood front profile created during the production flooding of an oil-bearing formation uti-lizes cased observation boreholes located between the injection wells and the producing wells.  The time and depth of arrival of the flood front at an observation borehole are detected by gamma ray spectroscopy examination of the formation.  Tracer elements having characteristic gamma ray emission energies are employed to facilitate detection of the flood front and its direction of travel.  The tracer elements may be naturally radioactive substances or they may be normally stable elements which are rendered radioactive by neutron bombardment.  Elements having interfering spectral lines may be separated on the basis of half-life measurements, selective detection periods or the response of the elements to different energy neutrons.  By repeating the detection process at different depths and times, the profile of the flood front as it approaches the producing wells may be developed.  This information may be used to control the flooding operating to prevent or localize premature breakthrough to the producing wells.

Abstract: Abstract of the Disclosure In apparatus for monitoring the operation of centrifugal cyclones sensing means is disposed in the underflow spray discharge of a cyclone and is connected to electronic sensing circuitry adapted to produce a signal or alarm response when the cyclone ceases to operate in a normal manner.  In one embodiment the apparatus employs a plurality of cyclones connected to receive feed material from a common manifold means.  Abnormal functioning of one cyclone of the group is immediately indicated by visual or audible alarm means and thereafter its sensing means may be disabled to permit the sensing circuitry to continue to be effective for the remaining cyclones.  Delay means is incorporated in the circuitry to prevent a response when the abnormal condition is of short duration.  One form of sensing means employs a probe which extends into the normal underflow discharge spray.  Another form employs a paddle and switch assembly, with the paddle extending into the normal dis-charge spray.
