Title: Process of forming a ceramic body
IPC: C04B35/468
Filed: 1952-01-23
Abstract: Ceramics, primarily of barium titanate, are obtained by heating raw barium titanate material, free from oxides actively catalizing reduction of barium titanate, in distinctly but mildly reducing conditions at above 600 DEG C. but below ceramic firing temperature, the said reducing conditions being present before the ceramic firing temperature is reached.  Subsequently oxidizing conditions may be utilized.  The reducing conditions are defined, as also is the term primarily barium titanate.  The presence of S04- in the raw material gives a better product.  The mass is shaped before the ceramic firing temperature is reached, and a temporary binder may be used. Specification 663,424 is referred to.

Abstract: 1,065,837. Brakes for winches. DORNIER SYSTEM G.m.b.H. Jan. 19, 1966 [April 10, 1965], No. 2476/66. Heading B8B. [Also in Division F2] A brake device for a cable drum 1 comprises a centrifugal braking arrangement and an additional braking arrangement operated just prior to the cable 10 being wound completely off the drum. The drum 1 is mounted on a brake mounting 2 rotatable about axis 0. The drum 1 and mounting 2 are locked together by a spring-loaded locking pin 11 held in the locking position by the last layer of cable on the drum. A brake shoe 3 is mounted on the brake mounting 2 and is movable radially under centrifugal force to engage a fixed brake drum 4 since pins 5 on the shoe 3 engage in radially elongated slots in the mounting 2. As the last layer of cable 10 is wound from over the pin 11 it springs up and the drum 1 rotates relative to the mounting 2. A cam plate 8 integral with the drum 1 is in engagement with a spring- loaded pressure member 9 in the brake shoe 3 and when the relative movement occurs, the pressure member 9 is caused by the cam plate 8 to increase the pressure of the shoe 3 on the brake drum 4 until the pressure member 9 engages a stop on the cam plate 8, whereupon the cable drum 1 is finally braked. A stopneedle 19 is used to hold the pin 11 in the locking position until the cable 10 has been wound far enough on to the drum. In further embodiments, Fig. 3 (not shown), two or more brake shoes are used, their operation being staggered for more gradual final braking.
