Title: Improved cooling of transformers with forced oil circulation - involves incorporating baffle elements to give turbulent flow
Inventor: UBL HEINZ DIPL ING
IPC: H01F27/32
Filed: 1974-05-10
Abstract: In a normal transformer construction the winding layers (1, 2) are separated by distance pieces (3) to give a series of ducts (6) through which the cooling oil is circulated. In these relatively regular ducts the coolant flow tends to be laminar with a consequent loss of heat transfer effectiveness. To give a turbulent flow short, rigid channel shaped insulation sections (4) are fitted over the distance pieces and provided with projections or vanes (5) into the oil duct. These act to disturb the flow and cause turbulence. By arranging the vanes to lie against alternate windings up the coil a zig}zag flow may also be introduced.

Title: 2-Hydroxy-3-naphthoic acid by carboxylation of beta naphtholate - using high shear agitation in the presence of beta naphthol
Inventor: BACHMANN WILFRIED DIPL ING
IPC: C07C51/15
Filed: 1974-06-04
Abstract: 2-Hydroxy-3-naphthoic acid (I) is prepared by reacting carbon dioxide on alkali metal salts of beta-naphthol in the presence of beta-naphthol at high temp. and pressure and the reaction is carried out being subjected to a continuous shearing action in time and space. (I) is an intermediate partic. used in the production of dyes. Previous dry processes have been slow (30-35 hrs) with difficult heat transfer and resinous by-products are formed. The above process reduces the amount of resins formed giving yields of 50-60% based on the alkali metal naphthalate used, also the reaction time is shorter and lower pressures may be used.
