Abstract: 920,388. Braking apparatus. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. May 5, 1961, No. 16449/61. Class 103 (1). [Also in Group XXVI] Braking apparatus for winding and like mechanism comprises a brake actuating linkage including a lever 16 which is acted on by a weight 20 through a draw-rod 19, spring 39, guide sleeve 37 and links 41 to apply the brake and by pressure fluid, e.g. air, acting in a cylinder 34 on a piston 28 connected to the lever by push-rod 26 to release the brake, there being provided a locking device which prevents upward movement of the weight when fluid is admitted to the cylinder 34 to release the brakes, so that the spring 39 is compressed, while it allows downward movement of the weight when the brake is applied so that wear of the brake linings or other factors affecting the position of the brake linkage are compensated for. The locking device comprises a rod 29 of square section secured to the support 35 for the lever 16 and cylinder 34, and a plate 30 pivoted at 36 to the draw-rod 19 and having an aperture in which the rod 29 is loosely received. The plate 30 thereby binds on the rod 29 during release of the brake but can slide downwardly on the rod 29 when the brake is applied. The brake comprises shoes 2, 3 carried by levers 4, 5 and engaging the exterior of a drum 1. The brake linkage comprises a bell-crank 11 pivoted on shoe 2 and one arm of which is connected by a link 8 to shoe 3, a further link 13 connecting the other arm to lever 16. Fluid-pressure cylinders and pistons. In a modification, Fig. 2 the cylinder 34 is provided with two pistons 28a, 28c which telescope one within the other, piston 28a being a close fit within the cylinder while piston 28c has substantial clearance in the cylinder bore. The push-rod 26 passes through a guide tube 28b secured to piston 28a and engages piston 28c. By this arrangement, should piston 28a seize in the cylinder when air is supplied to the cylinder to release the brake piston 28c will be free to return to its lowered position upon exhausting of the air from the cylinder so that the brake is re-applied. Passageways 44, 45, in the piston 28a, allow pressure to be equalized on its two faces. A cup washer 28d is carried by piston 28c.

The term " aquasol " also includes aquasols that have been flocculated by reason of containing dissolved metal salts. The quantity of dissolved salt in the " aquasol " can be above 0À1 g./1. and less than the quantity required for flocculation. The aquasol can also contain a U<SP>4+</SP>, (UO 2 )<SP>2+</SP>, Th<SP>4+</SP>, Pu<SP>4+</SP>, (PuO 2 )<SP>2+</SP>, (ZrO)<SP>2+</SP>, Be<SP>2+</SP>, or Y<SP>3+</SP> salt or mixture thereof and/or carbon (to form carbides) and surfactants. The NH 3 -releasing agent can be hexamethylenetetramine, acetamide, ammonium carbamate, ammonium cyanate or urea or a mixture thereof. The amount of NH 3 -releasing agent used may be sufficient to adjust the pH of the aquasol to 1À0 to 0À1 pH units below the gelation pH of the sol., e.g. an amount at least suficient to provide 70% of the stoichiometric quantity of NH 3  required to precipitate the salt. The total concentration of metal compounds in the aquasol, expressed as the oxides can be from 1 to 500 g./1. The liquid medium can have a solubility for water of 1-30% wt., e.g. C 4 -C 10  alcohol. The droplets and liquid medium can flow concurrently or countercurrently. The microspheres produced can be washed, dried and sintered to form the final microsphere pro - duct. Microspheres of a size range of 50-400Á are disclosed. The microspheres can be used as a nuclear fuel.
