Abstract: This invention relates to a method of reducing the particle size of solid particles and is applicable to the production of very fine particles of a wide variety of solids, includuing relatively hard solids. The method comprises milling a liquid suspension of solid particles in an agitated media mill (13), pumping the milled suspension through a particle size classification device (16) to separate the slurry into a coarse fraction (17) and a fine fraction (18), the particles of the coarse fraction having a greater median particle size than the particles of the fine fraction, recycling the coarse fraction (17) from the particle size classification device to the input of the mill (13), and recycling the fine fraction (18) by pumping (15) it to the classification device, wherein recycling of both coarse and fine fractions are continued until solid particles of the desired reduced particle size are produced. Preferably a single classification device and a single mill can be used, and particles having a median particle size of 0.3 microns or less and a relatively narrow particle size distribution can be produced, even using a hydrocyclone as the classification device.

Abstract: The rotary lock cylinder has a cylinder core (3) and a housing (1), hardened spring-loaded housing pins (4) and core pins (5) being mounted in radially extending bores. By means of a key to be inserted into the key channel (8), the tumbler pins (4, 5) are arranged so as to allow the rotation of the cylinder core (3). The cylinder core (3) has, in bores (10), pins (11) made of hardened steel which extend in the longitudinal direction of the cylinder core (3). The pins (11) are so arranged that, when a screw is screwed in, it is guided on the pins (11) and the core pins and housing pins (5, 4) are thereby pressed into the cylinder housing (1) to the extent of a spring block. When the screw is rotated further, the thread flights on the hardened tumbler pins (5) are peeled off. As a result of this measure, the screw has no hold in the cylinder and therefore cannot tear the cylinder or pull the core (3). <IMAGE>
