[Class 143.] In a crane having a jib raised and lowered.about a stationary axis and in which the load is transmitted to a weighing device through a bar 5, Figs. 1 and 2, guided by links 6, 7, the load acting on the upper end of the bar and the lower end of the bar acting on the weighing device, the points of engagement of the links 6, 7 with the bar and with the crane, or the connections 4, 11, 8, 15 with the bar and with the crane of members 17 .. 20 supporting the links 6, 7, lie on corners of a parallelogram so that the line joining the supporting points of each link remains parallel to itself when the jib is raised. The members 17 .. 20 carry knife edges for superposed pairs of links 6, 7, the members 18 and 20 being held vertical. Each pair of links may be replaced by a single link. The parts are duplicated at opposite sides of the crane as shown in Fig. 2. At each side, the jib 1 and a parallel rod 12, both pivoted to the crane framing 2, are joined at their upper ends by a tie 13. This structure remains a parallelogram as the jib is raised and supports the links 6. The upper end of the bar 5 carries the load pulley 3 and its lower end acts on the weighing device through a hanger 9 and lever 10. The jib is raised by tackle and the rope around the pulley 3 passes around a pulley 21 at the lower end of the bar 5 to a pulley 22. The connections 4, 8 may coincide as shown respectively with the pin 14 joining the tie 13 and the jib 1 and with the pivot 16 of the jib. With a long or jointed jib, the bar 5 and the rod 12 are sectional and the. junction of sections is guided by additional links. In a xnodification, the rod 12 is shortened at its lower end and its pivot 15 is replaced by an arcuate guide having its centre at 15, a link parallel to the tie 13 joining the lower end of the rod 12 to an intermediate point of the jib.

Title: Plant for Heat Treating Pulverulent Substances
IPC: F27B7/20
Filed: 1966-08-02
Abstract: 1,154,012. Preheating pulverulent material. SOC. DES FORGES ET ATELIERS DU CREUSOT. 2 Aug., 1966 [4 Aug., 1965], No. 34605/66. Heading F4B. Pulverulent material introduced at 3, and following path 4 is preheated by heat exchange with counter-current flowing waste gases following path 2, on its way to a rotary kiln 1. The heat exchange occurs in pre-heaters G1, G2, G3 and D each of which are succeeded by powder/gas separators S1 S2, S3, S4. A fraction of the waste gases is recycled through paths 6 and 7 respectively by fans 6b, 7b which are driven by motors 6d, 7d respectively, each controlled by a speed regulator 6e, 7e respectively. The gas recirculation rate through path 6 is controlled by the final pulverulent material preheat temperature measured by temperature detector T1. Additionally or alternatively this rate may be controlled by the waste gas temperature entering the preheating section D (Fig. 2, not shown). The recirculation rate through the path 7 is controlled by, the temperature in the other preheaters, the pulverulent material feed rate measured by dosimeter P, and the gas flow rate at the points m 1 , m 2  in the gas flow path as measured by pressure indicator M. The recirculation rate in the systems 6 and 7 may be compared by a manometer (C, Fig. 2) and the resulting signal used either to modify the pulverulent material feed rate, or to prevent imbalance between the two recycle rates by means of a regulating device (6g, Fig. 3) incorporated in one or both of the gas recycle paths. The recycle gases, for either of the paths 6, 7 may be drawn off downstream of the last separator S1, or upstream of the first preheater G1. They may be reintroduced at more than one point.
