Title: Continuous weighing of a consumable electrode
IPC: G01L1/12
Filed: 1966-08-03
Abstract: 1,136,964. Mounting arc furnace electrodes. WELLMAN INCANDESCENT FURNACE CO. Ltd. (Consarc Corp.). 3 Aug., 1966, No. 34756/66. Heading H5H. [Also in Division G1] A method of continuously measuring during melting the weight of a consumable electrode 16 for a vacuum arc-melting furnace, such as that of Specification 1,094,749, comprises placing a load sensitive transducer element between the electrode supporting-ram 12 and the electrode stub clamp 14. Clamp 14 is that of Specification 1,109,709. The apparatus 10 includes copper bushings 34, 35, conducting current to the electrode 16 through a copper tube 18, copper ram head 24 and electrode stub clamp 14. Bushing 34 has a cavity 38 containing four load cells 40-43 (see also Fig. 2, not shown), clamped by a pressure plate 46 on an elongatable rod 48 passing through the bushings 34, 35, and carrying a nut 52 for pre-stressing the load cells 40-43 via plate 46. Cells 40-43 are magnetostrictive devices varying in accordance with stress placed thereon, and conducting leads 58 transmit a signal proportional to the load on the cells, i.e. to the weight of the electrode 16, which signal is utilized to control the supply current or switch off the supply when the electrode 16 is almost consumed. Rod 48 has a greater modulus of elasticity than bushing 34 and, when electrode 16 is clamped in place, it elongates to a greater extent than bushing 34 to relieve the clamping stress on the load cells 40-43. The amount of stress relieved is proportional to the electrode weight, which decreases during melting. Instead of bushings 34, 35 and rod 48, a copper bellows-type bushing 62, Fig. 3 (not shown), may connect ram 12<SP>1</SP> and clamp 14<SP>1</SP>, the bushing 62 having a bore containing a tension-type stress detector element 66 with a resistance strain gauge 78 with leads 58<SP>1</SP> to a control circuit. The tension detector 66 is tensioned by the weight of the electrode, and as the bellows portion 64 of bushing 62 contracts the tension is relieved, to decrease the electrode weight measured by gauge 78 as the electrode is consumed. Alternatively, an annular bushing 80, Fig. 4 (not shown), is secured between ram 12<SP>11</SP> and clamp 14<SP>11</SP>, and has opposing holes 84, 86 providing maximum stress areas and having resistance strain gauges 88, 90 therein to indicate the stress on the bushing 80 and thereby the weight of the consumable electrode. In each embodiment the ram 12 is water-cooled to draw heat away from the load-sensitive element.

Filed: 1969-07-15
Abstract: 1,262,690. Seals. GENERAL ELECTRIC CO. 15 July, 1969 [17 July, 1968], No. 36498/69 Heading F2B. [Also in Division F1] In sealing means for a gas or steam turbine engine in which there are first, second, and third fluid chambers 12, 14, 16 and seals 24, 26 between the first and third chambers and second and third chambers respectively, high pressure fluid leakage from chamber 12 through the first seal 24 is utilized to reduce the pressure within the third chamber 16 adjacent the seal 26 by means of an ejector pump 40 to eliminate leakage through the second seal 26 from the third chamber 16 to the second chamber 14. The third chamber 16 includes first and second portions 47, 49. Such an arrangement utilizes the high pressure leakage fluid from the compressor 36 of a gas turbine engine to prevent its leakage into the chamber 14 which insulates an oil sump 32 and is fed with low pressure relatively cool air through a shaft passage 34. The ejector pump 40 comprises primary and secondary annular nozzles 42, 44, and an annular mixing throat 46 for receiving the fluid discharged by nozzles 42, 44, and these being formed from annular baffle elements 48, 50 co-operating with the chamber wall 18. The baffle elements 48, 50 are preferably formed of thin metallic sheet material and may be secured to chamber walls 18, 20 by fasteners 56, struts 58, or by a perforated mounting flange. High pressure fluid leakage from seal 24 flows into the portion 47 and is directed via nozzle 42 into the throat 46 drawing with it via nozzle 44 the fluid in the portion 49 and causing a reduced pressure therein. The mixing throat 46 may be formed as a divergent diffuser portion. Other variously formed baffle elements 48, 50 are shown.

Title: Safety closure for bottles
IPC: B65D41/34
Filed: 1976-08-26
Abstract: It consists of a cap (6) which can be screwed onto the mouth of the bottle and which bears a tamper-proof ring seal (7) at the bottom, separated from the cap (6) by a pre-broken join (9) defined by a plurality of short tabs (10) distributed around the circumference of the cap. The cap (6) and the ring (7) are provided with internal threads (5, 8) which extend coaxially and in opposite directions, which engage with corresponding threads on the bottle neck. By unscrewing the bottle closure, the cap (6) and the ring (7) move away from another as a result of their opposite threads, which causes the tabs (10) to break, separating the ring from the cap. The presence of a double thread in opposite directions on the cap and ring respectively, greatly assists the separation of these two elements since, as the seal is opened, there is a combination of tangential and axial forces which cause the ring and the cap to move away from one another. <IMAGE>
