Title: Improvements relating to converters for use in making steel
IPC: C21C5/50
Filed: 1961-12-21
Abstract: 924,026. Metallurgical converters. PINTSCH BAMAG A.G. Dec. 21, 1961 [Jan. 5, 1961], No. 45864/61. Class 72. A metallurgical converter is provided with a circumferential bearing ring having two coaxial, diametrically opposed hubs and two trunnions are shrink fitted, one in each hub. As shown, a bearing ring 1 of box construction welded to a converter shell has a hub 9 welded thereto at 10 and 12. The hubs are bored by a single boring bar so that the bores 14 are axially aligned and trunnions 4 having parts 15 of slightly larger diameter than the bores 14 are shrunk by immersing in liquid nitrogen so that the parts 15 become less in diameter than the bores 14. The parts 15 are then inserted into the bores 14 and allowed to warm up to room temperature to produce a shrink fit. Plates 13 may then be welded in place to form the inside of the converter shell. The trunnions may also be welded to the hubs at 17 and 18. In a modification, Fig. 7 (not shown), the converter vessel is supported in a bearing ring by claws and the trunnions shrink fitted in hubs formed in the bearing ring.

Abstract: 1,163,143. Obtaining fluid samples from mineral formations. SCHLUMBERGER TECHNOLOGY CORP. 14 Oct., 1966, No. 45916/66. Heading E1F. Apparatus for lowering down a borehole, to obtain a fluid sample from the formations traversed by the hole, comprises a seal 118, Fig. 3, engageable with the borehole wall and including a resilient annular member 124 with a rigid tubular insert 119, and a rigid compression member 128 behind member 124. Stop tube 140 is fixed to insert 119 and slides in member 128 to limit movement of member 124 into the formation of this erodes. Member 124 is pressed against the formation by borehole fluid acting in channels 132, 133, 134, 135, 135a. Body 165 forms part of a member which is lowered into the borehole and includes a hydraulic pressure system to move the body, and with it the seal, against the formation, a sample-receiving chamber, and measuring and control devices as is known in the art. Body 165 contains an explosive charge 160 which when fired ruptures cap 143 and a part of the formation to release a fluid sample, if present, which passes through tube 140 to passage 65 leading to the collecting chamber. In a modification, a snorkel 212, Fig. 8 is slidable in insert 119 and extended to pierce the formation by the hydraulic pressure system. In another arrangement, piston 213, Fig. 9, is integral with member 221 and is moved by the hydraulic pressure system to press the seal against the function. Borehole fluid also presses the seal as in the embodiment of Fig. 3. Several other embodiments, involving various constructional variations, are described. Reference has been directed by the Comptroller to Specification 904,131.
