Title: Apparatus for detecting leaks in steam raising boilers
Inventor: TERO BRIAN ALBERT
IPC: G08B21/00
Filed: 1983-10-26
Granted: 1988-07-07
Abstract: Apparatus for monitoring the escape of steam from the tubes of a power station boiler or the like employs a microphone located externally to the combustion space to sense an increase in combustion space noise level. At least one long narrow listening tube (12) leads from the combustion space (10) and has at its end an elbow (16) to which is sealed a microphone assembly (14) that senses the noise in the combustion space (10). Preferably a diaphragm (32) is interposed between the microphone assembly (20) and listening tube (12) that seals the end of the listening tube (12) while transmitting sound substantially unattenuated. The diaphgram (32) is a plastics sheet compressed between washers (30, 30a) that have an undulating line of contact. Noise from escaping steam at a frequency of 4-8 KHz may be detected with a gain of typically -20 db. The signal from the microphone assembly (14) is amplified (40, 42) and processed by means (49) to indicate the level of sound in the combustion space.

Abstract: There is described a prosthetic alignment device comprising at least two co-operating members (1,2) having opposing spherically curved faces. The faces include means for defining a direction of relative movement of the co-operating members and for calibrating that movement. The means for defining and calibrating comprise a row of teeth (14) on the said curved face (a) of one member (1) and a corresponding row of indentations (5) on the said curved face (b) of the opposing member (2). The rows of engaging teeth and indentations define the direction one member is to move relative to the other. The pitch of the teeth gives a predetermined angle of adjustment of the two co-operating members, and by counting the number of teeth or indentations visible the adjustment of the two members and consequently the alignment of the prosthesis can be immediately calculated.

Abstract: A contact member supporting member (40) is pivotably supported to a slide member (30) which abuts on a part of an IC card (1) to be inserted and is moved by the IC card. When the slide member moves, the supporting member also moves. The supporting member is swung in the direction of the IC card by fixed cams. Thus, contact members (50) of the supporting member come into contact with contacts (2) of the IC card. Since the contact member supporting member moves together with the IC card, the contact members do not slide on the surface of the IC card. Therefore, the abrasion of the contact members and the damage of the IC card which are caused by the slide friction between the contact members and the surface of the IC card, and the like can be prevented.
