Title: Tube joints in compressor discharge lines
IPC: B21D39/04
Filed: 1970-12-15
Abstract: 1311318 Pipe joints TECUMSEH PRODUCTS CO 15 Dec 1979 [24 April 1970] 59454/70 Heading F2G A pipe joint in the outlet of an enclosed compressor comprises a spigot and socket with a first seal means near the inner end of the joint, a second seal means near the mouth of the joint and a layer of adhesive between the two seal means. The adhesive may be an anaerobic adhesive, viz. an adhesive that solidifies in the presence of an hydroperoxide catalyst upon the exclusion of air or oxygen from the composition. In one form, a socket 34, Fig. 4, having an inner shoulder 32 receives a spigot in the form of a pipe 42. A reduced diameter portion 44 of the pipe separates a seal portion 50 at the pipe end from a seal portion 54. The end of the socket 34 has a flared mouth 37, 38. To form the joint, the seal portion 52 is introduced into the socket mouth 37, 38, but not pushed into the socket. The spigot and socket are held upright as shown. An anaerobic adhesive (56), Fig. 2 (not shown), in liquid form is poured into the ring- shaped space between the seal portion 50 and the flared mouth 37, 38 of the socket. The pipe 42 is slidden down into the-socket 34, Fig. 3 (not shown), carrying a layer (60) of the adhesive (56) with it, until the seal portion 50 of the pipe engages the socket shoulder 32, Fig. 4, when the seal portion 54 engages inside the socket. The adhesive is then allowed to cure to form a cylindrical annulus 62. Curing may be effected initially by induction or resistance heating, and completed by utilizing the heat applied in the compressor dehydration during the final stage of its manufacture. In another form, a socket 100, Fig. 5, has a crimped shoulder 106 spaced from its open end. A spigot 102 is introduced into the flared mouth 112 of the socket. An anaerobic adhesive 115 in liquid form is introduced into the ring-shaped space provided by the flared spigot mouth. The spigot 102 is slidden down into the socket so that its end 110 seats on and seals against the shoulder 106. A layer of adhesive (115), Fig. 6 (not shown), is thus provided between the spigot and socket. A second shoulder (118) is crimped into the socket, between the shoulder 106 and the socket end, sealing off the adhesive and locking the spigot and socket together. The adhesive layer (115) is then cured.

Title: Impregnating filamentary material
IPC: B29C53/80
Filed: 1979-01-15
Abstract: The disclosure describes a method of impregnating a filamentary tow, e.g. of glass or carbon fibres, with a liquid resin, in particular a thermosetting liquid resin. The method comprises applying the liquid resin (from 4) to the tow 1, which is preferably preheated at 3 to improve wetting, and then bringing the wetted tow into wiping contact with at least one smooth heated surface 8, 9. This ensures that the resin on the tow is rapidly heated, temporarily reducing its viscosity and causing expulsion of air bubbles trapped therein before any gelling or curing of the resin takes place. The method is suitable for impregnating filamentary materials used in winding filament-reinforced composite bodies, e.g. by winding on drum 2 whilst heating using I.R. lamp 14. <IMAGE>
