Abstract: A language specific microprocessor for the computer language known as FORTH is disclosed. The microprocessor includes four main registers each for holding a parameter; a L or instruction latch register for decoding instructions and activating microprocessor operation; an I or return index register for tracking returns; an N or next parameter register for operation with an arithmetic logic unit (ALU); and a T or top of parameter stack register with an appended ALU. A return stack port is connected to the I register and a parameter stack port is connected to the N register circuit, each have last in/first out (LIFO) memory stacks for reads and writes to isolated independent memory islands that are external to the microprocessor. The respective I, T and N registers are connected in respective series by paired bus connections for swapping parameters between adjacent registers.

Abstract: Water-dispersible polymers of an acid salt of 2-aminoalkyl esters of monounsaturated monocarboxylic acid and at least one comonomer are prepared by dissolving the salt of that ester in a coupling solvent, mixing the comonomers as a separate feedstock and bringing the monomers together in a polymerization zone at a controlled rate so that the monomers remain in solution and polymerizing to substantial completion.

Abstract: Properties of room temperatures cured epoxy resin coatings are improved by hydrolyzing at least a portion of the epoxy groups.

Abstract: A small hand tool such as a carpenter's hammer is disclosed as having a head which is pivotally connected crosswise to its handle. The head is provided with abutment faces which at different inclinations of the head to the handle are selectively aligned with the blunt end of a latch rod threadedly connected to the handle within a provided axially extending bore. Rotation of a larger-sized operating knob at the rearward end of the handle effectively advances and retracts the latch rod to releasably lock the hammer head to the handle in the selected position to which it is adjustable thereon.

Abstract: A single step in the form of a heavy forward displacing forging operation is used to manufacture cylindrically bored ferrous-metal multiple diameter nozzles with an outside diameter of at least 22 inches, weighing at least 4,000 lbs. and possessing an exterior configuration comprising a round cylindrical base section of largest diameter with an outwardly-extending flange at one extremity, spaced second cylindrical section of smaller diameter, and an interconnecting and intercommunicating frusto-conical section.

Abstract: A far less expensive process of manufacturing heavy-duty welding necks, nozzles, and similar connector elements comprising cylindrical bodies with a radial flange at one end, is provided through the utilization of a centered metal-displacement disc which contacts a radially flanged heated billet after the forging operation and forces the metal under the centered disc and interiorly of the radially-flanged portion into the die cavity and around a rounded centrally disposed supporting member which initially is in contact with the underside of the work-piece. This forward displacement action is continued until the advance portion of the work-piece contacts a circular forging knife which is carried on the interior of the female forging die member.

Abstract: Large, heavy-duty, seamless high-pressure resistant ferrous-metal welding necks and other substantially thick-walled cylindrical articles are forged in such manner as to obtain greatly improved quality, dimensionally, metallurgically and otherwise, by the use in sequence of a certain combination of metal-forging elements; which includes a vertically disposed cylindrical female forging die member provided at its bottom with a removable disc and a surrounding circular forging kinfe; an annular metal-working and metal-displacing ring having an external diameter which is slightly less than the bore of the cylindrical female forging die member; a metal-working and metal-displacing disc which interfits with the annular metal-working and metal-displacing ring; a first round forging press follower of a diameter which is adequate to entirely cover the metal-working and metal-displacing disc and a substantial portion of the annular metal-working and metal-displacing ring; a second round forging press follower of a diam

Abstract: Large, heavy-duty, high-pressure resistant cup-shaped ferrous metal industrial products possessing substantially thick-walled cylindrical barrels are forged in such manner as to obtain greatly improved quality, dimensionally, metallurgically and otherwise, by the use in sequence of a combination of metal-forging elements which includes a cylindrical female die member; an annular metal-working and metal-displacing ring having an external diameter which is only slightly less than the bore of the cylindrical female forging die member and an internal diameter which is only slightly greater than the external diameter of a metal-working and; a metal-working and metal-displacing disc which interfits with the annular metal working and metal-displacing ring; a first round forging press follower of a diameter which is adequate to entirely cover the metal-working and metal-displacing disc and a substantial portion of the annular metal-working and metal-displacing ring; and a second round forging press follower of a diam

Abstract: Solid particles, such as medicinal preparations, are tested for resilience in a fluidizing apparatus. The test of this invention has several applications, such as predicting abrasion loss for particles which are to be coated in a fluidized bed coating operation, estimating abrasion loss for particles during shipping, and predicting disintegration rate of particles in fluids.
