Abstract: Subjecting 1,4-bis-[(pyrrolin-3-onyl)methylamino]-2-butyne to ultraviolet irradiation effects rearrangement in greater than 80% yield to 1,4-bis-[(isocyanatocyclopropyl)methylamino]-2-butyne. The diisocyanate is useful in the synthesis of polyurethanes and polyureas and also for the in situ photochemical generation of a cross-linking agent for polyurethanes and structurally related polymers.
Abstract: A method for diagnosis of rheumatoid arthritis and related autoimmune diseases comprises blocking calcium ions contained in a blood sample, effecting hydrolysis of a selected substrate in the presence of .alpha..sub.2 -macroglobulin (.alpha..sub.2 M) from the blood sample, and determining the extent of hydrolysis of the substrate. Preferably, .alpha..sub.2 M in plasma is incubated with a hydrolyzable chromogenic substrate and the liberated chromogen is determined spectrophotometrically. A diagnostic kit is also provided.

Abstract: Improved additive compositions comprise sulfurized, esterified, unsaturated polycarboxylic acids. Such additive compositions possess good solubility in oils and impart improved lubrication and anti-oxidant properties to lubricant, fuel, and metal-working compositions.
Abstract: This invention relates to a highly efficient refrigeration system and process, employing two absorption refrigeration cycles in series operation, the first cycle comprising an ammonia-aqueous ammonia system and the second cycle comprising a novel absorption system and process, driven by low-grade heat and operated at pressures substantially below atmospheric, which provides cooling at temperatures as low as about -12.degree. C. to about +15.degree. C. Solutions of normally liquid, mutually soluble compounds, having substantially different boiling points, are employed as refrigerant and absorbent. Typically, the absorbent comprises a distillation bottoms fraction containing from about 65 to about 95 mole % of the higher-boiling compound and the refrigerant comprises a distillation overhead fraction containing from about 93 to about 99 mol. % of the lower-boiling compound. Heat pumped up in the first ammonia cycle is absorbed in the second cycle by refrigerant at the coolant temperature achieved therein.

Abstract: A means and method for comparing an incoming sequential string of digitally encoded characters from a database stored in a conventional memory against a pattern with an arbitrary number of elements, comprising specified characters or character types (alphabetic, numeric, delimiter, etc.) or tokens to indicate the matching of a specified or arbitrary number of input characters, is disclosed. The system comprises a number of digital machines, sequenced by control words fetched from their memories. The control words may indicate the current input character or character type of interest for each machine, the address of the potential next control word of the machine, a flag indicating the successful completion of a match, and other control fields.
Abstract: The present invention prepares protein hydrolyzates by reacting selected protein material with at least one proteolytic enzyme and recovering the low molecular weight protein material by ultrafiltration while recycling the high molecular weight material and proteolytic enzyme for further hydrolysis. A series of ultrafilters of varying permeability may also be used.
Abstract: Means for compensating for third and higher order aberrations in an electron optic system comprises two sextupoles and a field lens, the latter being spaced intermediate the sextupoles. The resolving power of the optic system can be reduced to the range of about 0.5 Angstrom unit.
Abstract: A method for diagnosis of rheumatoid arthritis and related diseases comprises determination of polyclonal lymphocyte activation in B-cells cultured in the presence of patient serum. A diagnostic kit is also provided.

Abstract: A system and method for controlling the temperature of the contents of storage vessels integral with an automotive transport power system, which includes a fluid-cooled internal combustion engine, is provided. A portion of the engine coolant fluid is circulated from the engine through one or more heat-exchange pipe coils, each located within a storage vessel carrying diesel fuel, compressed air, hydraulic oil, or the like, for use in automotive transport, to maintain a selected operating temperature in response to a temperature sensor. An auxiliary heating and pumping system is provided for use when the transport system is not in operation. The control system is particularly useful whenever the atmospheric temperature is high (above 90.degree. F.) or low (below 35.degree. F.).
Abstract: Coal is gasified, to yield a fuel gas having a medium-B.T.U. heating value, in the presence of air and steam in a plurality of reaction stages having different reaction temperatures. Reaction heat is principally supplied directly by recycle of char particles from a separate combustion zone to higher-temperature reaction zones and indirectly by combustion flue gas to lower-temperature reaction zones. Hydrogen sulfide, from product fuel gas, and flue gas are directly contacted to provide elemental sulfur. The only other product is a substantially non-combustible ash.

Abstract: Electric power is provided during periods of peak demand, employing a turbine generator facility activated by the expansion of compressed air, withdrawn from an underground air storage reservoir, in a substantially isothermal system. A generator system, which may comprise a steam boiler or a fuel gasifier, is employed for isothermal compression of air into reservoir storage during periods of low power demand.
