Abstract: A method of mechanically frothing and casting an aqueous polyurethane dispersion yields a foam which, when rolled, wound or stacked, is self-releasing from the pressure sensitive adhesive layer co-cured therewith. The method includes admixing an aqueous ionic polyurethane dispersion with a stearate stabilizer and an optional aziridine crosslinking agent, frothing and casting the admixture, and co-curing the resultant foam sheet with a pressure sensitive adhesive layer. Before frothing, the polyurethane dispersion contains particles having an average size of less than one micron, and contains between 35 and 70 percent by weight of the polyurethane dispersion, between 13 and 50 percent by weight of a 33 percent by weight dispersion of a stearate salt, and up to 33 percent by weight of a polyfunctional aziridine. The foam produced from the frothed admixture provides a substrate with which an uncured pressure sensitive adhesive can firmly co-cure but to which the cured adhesive demonstrates readily removable adhesion. The laminate of the foam with a pressure sensitive adhesive thus provides either a medical dressing, or a general purpose tape for industrial use, which may be stacked or self-wound without release paper.

Abstract: Polyetherimide oligomers having crosslinking end cap moieties which provide improved solvent -resistance to cured composites are generally represented by the formula:
        E = allyl or methallyl; 
R = a trivalent C (6-13)  aromatic organic radical; 
R₁ = any of lower alkyl, lower alkoxy, aryl, or substituted aryl; 
Rʹ = a divalent C (6-30)  aromatic organic radical; 
j = 0, 1, or 2; and 
G = -CH₂-, -O-, -S-, or -SO₂-. 
Blends generally comprise substantially equimolar amounts of the oligomers and a comparable, compatible, noncrosslinking, etherimide polymer of substantially the same backbone. The crosslinkable oligomers are made by reacting substituted phthalic anhydrides with hydroxyaryl amines and suitable crosslinking end cap   reactants, or by self-condensation of phthalimide salts followed by capping the polymers. Related polyetherimides of the present invention can be prepared by the condensation of nitrophthalic anhydride, diamines, dialcohols, (dihydricphenols), and phenolic, crosslinking end caps (A-OH), or the condensation of bis(phenates) or dialcohols (bisphenols), diamines, nitrophthalic anhydride, and amine-terminated end caps (A-NH₂) or nitro-terminated end caps (A-NO₂). 
     The oligomers and blends can be prepregged, and can be cured to form advanced composites having aerospace applications.

Title: A process for preparing highly crystalline Poly-1-butene and the catalyst used in the process
Inventor: TERVONEN JARI
IPC: C08F10/08
Filed: 1988-07-06
Abstract: When polymerizing 1-butene either alone or together with minor quantities of (below about 10%)of other unsaturated monomers, a Ziegler-Natta- composition may be used as high-yield-catalyst, in which, by means of a combination of a solid tetravalent Ti compound supported on MgCl₂, an organic Al compound and possib­le electron donors, liquid hydrocarbon containing 5 to 12 C atoms has been prepolymerized. With this prepolymerized catalyst compo­sition 1-butene may be polymerized particularly in a gas phase. The catalyst composition obtained and the final 1-butene polymer are highly crystalline and do not adhere to each other, and are thus easy to handle and most fluid. The mechanical properties of the product polymer, such as hardness, elastic modulus, tensile strength, yield point, impact strength, etc., are high, and the optical properties, such as light transmission, are equally good.

Abstract: A compact housing 10 and disk stack subassembly for use in a data recording disk file permit the disk stack subassembly to be located entirely within and axially secured to the parallel interior walls 12, 14 of the housing 10. The disk stack subassembly includes an in-hub motor having a stator assembly 60 which is secured to a lower bearing support 42. The lower bearing support 42 is axially movable with respect to the outer race 33 of the lower bearing assembly 24. The inner race 27 of lower bearing assembly 24 is attached to the rotatable shaft 20 of the disk stack subassembly. The lower bearing support 42 and the attached stator assembly 60 are biased axially by means of disk spring 52 in the direction of the cavity 35 where the in-hub motor is located. Thus, the overall axial length of the disk stack subassembly is less than the axial distance between the parallel interior walls 12, 14 of the single piece half shell housing 10. This permits easy insertion of the completed disk stack subassembly into the housing 10 and connection thereto by means of axially aligned bolts 59, 61 which are threaded into upper bearing support 40 and lower bearing support 42. When bolts 59, 61 secure the disk stack subassembly to the walls 12, 14 of housing 10, disk spring 52 is compressed to thereby apply an axial preload to lower bearing assembly 24, which prevents axial movement of the disk stack during operation of the disk file.

Abstract: In the conventional supply of cold to a cold consumer by an ice storage device and a liquid cooler, the generated cold is fed by means of intermediate circuits both to the ice storage device for charging it and to a cold-water circuit circulating through the cold consumer. To obtain the temperature gradient necessary for the functioning of the intermediate circuits, the evaporation temperature of the associated refrigerant circuits has to be reduced correspondingly, thereby impairing the efficiency. The cold is therefore transferred by direct heat exchange to the ice storage device (36) and to the cold-water circuit (66) in which the cold consumer (68) is inserted. This allows an increase in the evaporation temperature of the refrigerant and thus ensures an increase in the performance number and efficiency. <IMAGE>

Abstract: A tractor implement draft force control system in which desired and actual implement draft force values are compared to provide a draft force error signal (DE). The system includes a gain control means (GC) which process the actual draft force signals so that at draft force signals above a predetermined level the increase in draft force signal (AS) per unit increase in draft force is reduced. Typically in the upper one-third of the draft force range the rate of increase in draft force is only one half of the rate of increase in the lower two-thirds of the draft force range. This has the effect of allocating significantly more of the total movement of the draft force setting control to the draft force range of implements such as moldboard and chisel plough which require more accurate control.
