Title: Minimum energy process for preparing block copolymers  of polyamides
Inventor: NICKOL STEPHEN L
IPC: C08G69/40

Granted: 1980-11-18
Abstract: Process for preparing block copolymer involves dry blending salt of a prepolyamlde, e.g. a 30203-6 salt, and particules of melt-spinnable polyamide.  Blend is heated to a temperature in the range of between from the melting point of higher melting component to below amide-interchange temper-sture of a blend of the melt-spinnable polyamide and the homopolymer which would result from the polymer-iration of the salt.  Heating and mixing are continued until substantially all of the salt and the polyamide are converted into a block copolymer.  The latter can be used to make fibers.

These transistors have gate elec-trodes self-registered with source and drain electrode regions and are formed at crossings of a plurality of parallel first conductive tracks, which comprise the transistor gate electrodes and a plurality of parallel strip-shaped surface regions of opposite conductivity which adjoin a surface of the body. The surface regions comprising the source and drain electrode regions. A first group of transistors are of a first form hav-ing a first threshold voltage and a second group of transistors are of a second form having a second threshold voltage. The logic input signals are to be applied to the gate electrodes of one of the two groups and the logic combination to be gen-erated is determined with the aid of the crossings and form of transistor present at these crossings and with the aid of the interconnection of transistors of this one group via the op-posite conductivity type strip-shape surface regions. The cir-cuit is characterized in that the array is an irregular array and the logic combination is additional predetermined with the aid of further interconnections, formed by branching of the strip-shaped regions, within the array.

Abstract: ABSTRACT OF THE DISCLOSURE    A Stirling Cycle machine having a cylinder mounted in a housing has a displacer reciprocably mounted in the cylinder.          Also reciprocably mounted in the cylinder is a piston and passages are provided in the cylinder so that when the displacer moves in one direction, a cooled gas will be drawn into the cylinder be-tween the displacer and the piston, and when the displacer moves in the opposite direction, a heated gas will be drawn into the cylinder to thus provide expansive gas forces working against the piston thus causing the piston to be driven in its power stroke when the machine is utilized as an engine.  The piston is drivingly connected to a crankshaft and the displacer is driven by a crank-shaft, which is in rotative synchronism such that the displacer movement in the cylinder in the direction to draw heated air into the cylinder overlaps in time a substantial portion of the piston power stroke.  The lengths of the connecting rods between each of the displacer and piston and their respective crankshafts are so proportioned to the respective crank throws that the displacer is so driven in its reciprocable cycle that it is provided with a long dwell within a given range of displacer movement near the end of displacer travel in the one direction which moves cold air into the cylinder and a relatively short dwell in the other direction which moves hot air into the cylinder.  The piston dwell in a pre-determined range of piston movement near the beginning of the power stroke is less than the piston dwell during the same prede-termined range of piston movement near the end of the power stroke.          Thus, a more of efficient Stirling Cycle engine is provided.

Abstract: ABSTRACT OF THE DISCLOSURE           An inventive composition has fat fraction comprising about 15-40 parts cocoa butter, about 0-25 parts butterfat, with the sum of the parts of cocoa butter and butterfat being not substantially in excess of about 40, and about 60-85 parts of a special confectioner's hard butter.  Such hard butter is essentially all 16-18 carbon atom triglycerides, is chemically quite dissimilar from cocoa butter, and has an SFI profile and melting characteristic somewhat higher than cocoa butter. Surprisingly, such hard butter can be a fine replacement fat for cocoa butter, particularly when the composition contains some butterfat.  A finished confectionary food composition, typically compounded with chocolate liquor, optional butterfat, sweetener such as sucrose, lecithin and flavor, exhibits excellent hardness, snap, and initial and retained gloss when compared to present United States chocolate counterparts. Accordingly, the composition can be used in such applications also.    Such special hard butter also is claimed, as well as is an improvement in process for making same.  Such improvement involves redissolving in solvent a hard butter fraction cropped from the systematic and successive fractional crystallization of a fat that has a high percentage of its fat-forming acids in the trans configuration, then cropping out the preponderance of such hard butter product a? product while retaining a small proportion of it in the mother liquor, which proportion becomes enriched in unsaturated components.
