Abstract: ABSTRACT        Unsymmetrically 3,6-substituted 1,4-dioxane-2,5--diones may be polymerized to give living-tissue absorbable, hydrolytically degradable surgically useful polymers.  These polymers have predominantly regular rather than random spacings of side chains, may be stereoregular and tend toward higher cryatallinity than radomly sequenced polymers.  A polymer of 3-methyl-1,4-dioxane-2,5-dione has the same empirical formula as an equimolecular copolymer of lactic and glycolic acid but has unique physical properties resulting from its more regu-lar steric configuration.  Polymers and copolymers of 3- and 3,6-unsymmetrically substituted 1,4-dioxane-2,5-diones have surgically useful mechanical properties. On implantation, in living mammalian tissue, the polymers are absorbed, and re-placed by living tissue.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to systems for reading and changing codes of spot magnetized cards.  Spot magnetized cards have been described where-in polarities of magnetized spots on the card are to be removed with each use to represent a lower value.  However, available systems using such cards are not able to identify the card with particular apparatus to be actuated thereby.  The present invention provides a system for cooperably relating both identification and value/use codes in the same card so that normal operations of associated control circuits are mutual prerequisites for actuating end use apparatus and changing the value/use code, or where-in the value of a card can be verified without effecting operations of either the end use apparatus of the code changing means.  According to the invention, a card is spot magnetized with a value or use code, in which the polarities of the spots at one card surface are distributed in accordance with the Gray code in the described arrangement, and with an identification code.  Polarity reversing electromagnets with bifilar windings are arranged so that respective spots of the Gray code are aligned therewith.  Electro-magnet sensors with which each spot of each code are aligned are utilized via logic circuits to cause a clock generator to produce pulses for use in operating end use apparatus and for selectively energizing an electromagnet winding in a direction that reverses the associated spot to establish a decremented value/use code.

Abstract: ABSTRACT OF THE DISCLOSURE               There is described a process for preparing metal articles having the property of repeatedly reversible shape memory effect.  The process comprises applying deformation stress to a .beta.-brass type martensitic Ni-Al alloy consisting essentially of 55 to 65 at % of Ni and the remainder Al at a temperature below Md point.  The value of the deformation stress is within a range exceeding the first yield point of martensite crystal in the alloy beyond easy plastic flaw region but below the point at which a large amount of permanent strain is produced by glide deformation.  The metal articles prepared by this process have excellent repeatedly reversible shape memory effects and other metallurgical properties such as durability, toughness and workability, and can be used in pressure, temperature, electrical, magnetic and optical sensing devices.
