Title: Method for increasing the carbon yield of resins and reducing  the porosity of carbon composites
IPC: C04B35/52
Filed: 1971-05-10
Abstract: 1335127 Carbon UNITED STATES ATOMIC ENERGY COMMISSION 10 May 1971 [10 June 1970] 14085/71 Heading C1A In pyrolysing a carbonaceous material by heating it in an inert atmosphere at a carbonizing temperature, the yield of carbon from the carbonaceous material is improved by enclosing the material in an envelope formed of stainless steel, or copper, iron, nickel or alloys thereof, the ambient environment of the envelope being gaseous, and the envelope being permeable to hydrogen and impermeable to carbon yielding gases, and heating the enclosed material at a temperature sufficient to cause carbonization; this producing the evolution of hydrogen and carbon containing gas, the evolved hydrogen escaping from the envelope, the carbon containing gas remaining in the envelope where it is converted to carbon by the heating. The carbon material preferably comprises an impregnated carbon body, which impregnant is carbonized during the process of the invention, and the contents of the envelope are subjected to a pressure loading sufficient to maintain the impregnant in the body during carbonization. The preferred impregnants are pitch, trioxenes, naphthalenes, indenes, fluoranthene, and mixtures thereof. A greater quantity of impregnant may be confined in the envelope than is necessary to fully impregnate the carbon body, and the pressure loading is sufficient to force an amount of impregnant into the body as to fully impregnate it. The pressure loading may correspond to a pressure in the range 10,000-20,000 p.s.i., the carbonization temperature being in the range 700‹ to 1000‹ C. Preferably the inert atmosphere in which the envelope is confined is at a pressure adequate to effect the desired pressure loading and a temperature sufficient to effect said carbonization. The pressure applied may be such as to deform the envelope and compact its contents. In an alternative embodiment arrangements are made so that the interior of the envelope and its ambient atmosphere are at the same pressure so that the desired pressure loading may be achieved without compacting the contents of the envelope.

Abstract: 668,597. Locking switches; electromagnetic switches. COULSON, C. W. A., and ALFORD, F.R. June 14, 1950. No. 14889/50. Class 38 (v). [Also in Groups XXVII and XXXVIII] A switch utilised in a theft alarm device for motor vehicles (see Group XXXVIII) includes a number of manually settable locking members which prevent restoration of the switch to the inoperative position save when each of the settable members is at a predetermined setting. The arrangement comprises a box 34 on the front of which dials 35 are provided; each associated with a handle 36 attached to a rotatable shaft carrying a circular locking plate 39 and a toothed disc 38. Spring-loaded pawls 40 engage and hold the discs 38 in positions corresponding to the dial markings. Each locking plate 39 comprises a disc of insulating material 42 and an attached metal disc 43, and is provided with a cut-out 48 permitting passage, in a predetermined position, of the switch operating member 1. The discs 43 are conductively connected by a contact spring 44. The switch operating member 1 is provided with a knob 2 and is slidable in a longitudinal direction ; the portion 50 is conductive and carries a bracket 51 to which are attached pawls 47 loaded by a common spring 46, the arrangement being such that the member 1 may be pushed in irrespective of the positions of the locking plates 39, but may then be withdrawn only if both locking plates are in their chosen positions. If an attempt is made to withdraw the switch operating member with either locking plate in an incorrect position a circuit is completed via the spring 44, the disc 43 and pawl 47 which causes the alarm to be sounded. To prevent an attempt to "feel" the correct positions of the locking discs by applying a pull to the member 1 while one handle is rotated, studs 53 are provided in the discs 43 which successively engage the pawls 47, so that the disengaging positions are not distinguishable. The switch operating member 1 also comprises an extension piece 52 of insulating material by which the contacts 8 are operated, being part of the theft alarm circuit (see Group XXXVIII). The arrangement also includes a relay 19, one pair of contacts of which, 58, close immediately the armature 54 is operated, and the other 55, 56 open after a time-delay, the moving element 55 being provided for this purpose with a bentback portion, the free end of which is engaged by the armature.
