Title: Safety device for the arbor of a machine tool, especially a fastening machine
Inventor: HO KWANG-LIANG
IPC: F16P3/16
Filed: 1984-10-11
Abstract: A safety device is embodied in a fastening machine having a driving sleeve (1), an upper mould square mandrel (2), a first copper sleeve (5) and a second steel sleeve (6). On the driving sleeve (1), there is provided four square holes (104) each of which houses a roller (105), and at the circumference of the mandrel a flange (203) is provided. The rollers (105) run in rectangular sectioned slots (501, 602) in the sleeves (5, 6). The placement of positions of the rollers and the flanges, and a difference between the inside diameters of the slots in the copper sleeve and the steel sleeve enable the pressing and the safety modes. For the pressing operation the rollers engaging the upper surface of the flange run down the slots when the driving sleeve and the mandrel move synchronously and the pressing action occurs when the rollers are in the slots of the steel sleeve which has a slot diameter precluding the flange moving back over the rollers. However if the downward moving mandrel is blocked by an external factor (e.g. the operator's finger) the driving sleeve continues to move and the rollers moving in the slots of the copper sleeve can move over the flange to a safety position, so that the mandrel cannot accept a mechanical crushing force from the driving sleeve. This prevents the operator's finger from being crushed by the mechanical crushing pressure between upper and lower moulds of the machine. A pin-and-slot arrangement is provided to enable free (safety) movement between the driving element and the mandrel. <IMAGE>

Title: Monitoring a heterogeneous transformation process
Inventor: PAL DR GABOR
IPC: G01H3/00
Filed: 1985-02-14
Abstract: A heterogeneous transformation process taking place in a liquid, e.g. the desulphurization of steel, which produces vibrations, is monitored by detecting vibrations produced therein 1. The vibrations are subjected to spectral analysis and, in signal processing circuit 3, is divided into two frequency ranges (figures 3 and 4). The ratio of the (average) vibration amplitudes in the two frequency ranges is formed, and this enables instantaneous values for a diffusion coefficient of the transformation process to be calculated, so that the end point of the process may be determined. Automatic control of the process is also envisaged. <IMAGE>
