Patent DE-19829872-A1 (DE)
Title: Test procedure for a nitrating furnace
Inventor: STEINMANN HELMUT
IPC: F27D19/00
Filed: 1998-07-03
Abstract: It is known that ammonia dissociates at temperatures above 45  deg C. It is also known that the catalytic property of the furnace walls changes after a few weeks of operation. It is desirable to check the effectiveness of the catalyst at regular intervals. The empty furnace is heated to 450  deg C and filled with ammonia at atmospheric pressure. The gas line is then closed and the rise in pressure is measured over a period of between 5 and 15 minutes. A high rise indicates deterioration of the catalyst. Such a test is important to determine if incomplete nitration is due to a passivated surface on the workpiece or an inefficient process.

Title: Bearing rigidity evaluation apparatus for evaluating the rigidity of a bearing to which a preload is applied
Inventor: TADOKORO HISAKAZU
IPC: G01M7/02
Filed: 1999-08-27
Abstract: The apparatus includes a vibrator (1) which excites a bearing (4) to vibrate. Output signals of outer race vibration detecting sensors (21b,21c) for an outer race (42) are added up in time sequence by an adder (23) and then supplied to a transfer function computing unit (3a). An output signal of an inner race vibration detecting sensor (21a) is also supplied to the transfer function computing unit. The transfer function computing unit calculates a transfer function H between the inner and outer races (between a hub shaft (41) and the outer race (42)) by fast Fourier transformation. On the basis of this transfer function H, there is obtained a vibration mode in which a resonance frequency fa appears in a position of - pi /2 phase difference from local-mode vibration components (in-phase components) contained in the input signals after erasing of the local-mode vibration components. A rigidity transformation computing unit (3c) determines the bearing rigidity on the basis of the resonance frequency.
