摘要: 1,206,979. Tubes; valves. RAYCHEM CORP. 2 Nov., 1967 [3 1966], No. 49794/67. Headings F2P and F2V. [Also in Divisions H1 H2] A sleeve of material having the property "elastic memory" is axially stretched while a heated state frozen condition so that its heat recovery will be axial direction. While 50 illustrated described as bringing conductive members 60, 52 together guided by 56 to make electrical contact (see Division H2), one could open or close valve response rise temperature. The recoverable may plastics metal respect latter Specification includes some literature references. also have been twisted it untwists on recovery.
