Abstract: 783,147. Bridge cranes. DARMSTADTER, F. Oct. 17, 1955 [Oct. 16, 1954; Jan. 29, 1955], No. 29481/55. Class 78 (4). To accommodate irregularities in the trace along which the bridge of a bridge crane travels one of the bogies 11, Fig. 3a, supporting the bridge can slide and articulate relatively to the bridge. In the construction illustrated one of the members 5 forming the bridge slides within a guide 23, Figs. 6 and 7, pivoted at 24 in the bogie frame 11. Rollers 21, 26 and a slideway 22 guide the member 5 while a second member 5a of the bridge merely rests on rollers 21. The wheels 8a are directly journalled in the bogie 11 while wheels 8 in a bogie 7 secured rigidly to the opposite end of the bridge are carried at opposite ends of a pivoted equalizing bar. The wheels 8, 8a are driven by pinions through shafting 17 formed with sliding couplings 19 and universal joints 20. The wheels may be flanged, or alternatively horizontal rollers 10, Fig. 6, may engage the sides of the tracks. In alternative constructions one of the bogies 7, 11 may have a single central wheel so that no equalizing lever is needed and the articulated bogie 11 may be carried by a single stub projecting from the bridge, or may be rigid with a pair of stubs suitably guided in the bridge.

Title: Process for the manufacture of alkali metal trimetaphosphates
IPC: C01B25/445
Filed: 1965-07-13
Abstract: Alkali metal trimetaphosphates (e.g. Na3 P3O9) are made by introducing an alkali metal oxide, hydroxide, chloride, carbonate or nitrate (in solid form or in solution) into a flame fed with phosphorus, preferably liquid, and an O2-bearing gas (e.g. air); allowing the resulting phosphate melt to solidify; maintaining the solidified melt at above 300 DEG  C. but below its m.p. for 1-30 minutes, preferably 5-10 minutes; and then allowing the solidified melt to cool to ambient temperature.  The proportions of starting materials are arranged to give a mole ratio of alkali metal oxide : P2O5 of 1 : 1.  The process may be carried out in a single stage by pouring the melt into a container of at least 100 l. capacity so that the cooling is sufficiently slow at first, or continuously by allowing the phosphate melt to solidify on an endless belt which travels through a heat-insulated tunnel, the length of which and velocity of the belt being adjusted to give the required residence time at above 300 DEG  C.  The product is substantially pure trimetaphosphate.
