Inventor: ORGAN ALAN HENRY
IPC: F16H25/24
Filed: 1991-01-24
Abstract: A thread seal comprises a helical rib (6) for use with a threaded member (1). The end portions (7) of the rib (6) are axially staggered and are joined by a transverse thread bridging member (8) which engages a crest (9) of the thread between sucessive turns of the groove (2).

Filed: 1991-08-28
Abstract: An apparatus is disclosed for maintaining records for dental treatment. A registered user of the apparatus has his or her name and address stored in a randomly distributed manner in a systems parameters database 15 in a user-unalterable manner which is integrally linked with a security code. A control unit 2 includes circuits constructed to retrieve the name and address on printing of documents at a printer 7. Accordingly, the name of an unauthorised user will not appear on the documents. Thus, unauthorised use is discouraged in a simple manner. Video controller instructions for a graphical outline chart representing teeth are stored in a graphical record database 13 together with treatment codes for each patient. The treatment codes are used by the control unit 2 in generation of pixels of different colours indicating (Fig 2) treatment required or already carried out.

Title: Feedback controlled noise source for acoustic testing
Inventor: MIDDLETON ANDREW HENRY
IPC: H04R29/00
Filed: 1991-10-23
Abstract: The noise source has a rigid cone 1 supported via a flexible diaphragm 2 at an aperture 3 in a generally spherical steel enclosure 4. The enclosure 4 is hollow and partially lined with sound-absorbent material 5 to absorb noise within the enclosure. The enclosure ensures that noise from the source is propagated only from the exposed face of the cone. Within the enclosure at the aperture, a loud speaker coil drive assembly 6 is mounted for driving the cone. Rigidly fixed on the outside of the rigid cone is a conical extension 7. At its forward end, this carries an accelerometer 8 oriented to measure acceleration of the cone towards and away from the drive assembly and thereby to enable feedback control of the cone's movements. This allows for an accurately reproduced sound to be introduced into a room for room calibration purposes. <IMAGE>
