Title: Seals
IPC: C04B38/00
Filed: 1979-03-14
Abstract: A high temperature resistant seal which will tolerate temperatures in excess of 1400 DEG C comprises a fireproof sealing material comprising fibres of ceramic material, preferably formed into tissue and/or soaked in a fireproof binder. Silicon dioxide and aluminium oxide are suitable ceramic materials and waterglass is a suitable binder.

Title: Opto-electronic identification of combustion line of wrapper encasing smokable article
Inventor: PANGRITZ DR DIRK
IPC: G01N21/55
Filed: 1982-11-05
Abstract: In order to identify the combustion line (2) of the wrapper encasing a smokable article (e.g. the combustion line of cigarette paper, wrapper leaf or synthetic wrapper), the degree of reflectance at the surface of the smokable article (3) is monitored by one or more optical sensors (RL1, RL2). The combustion line (2) can be identified by means of the sudden change in the output signal from the sensors (RL1, RL2) as it registers the transition from ash to wrapper at the combustion line (2). By causing the sensors (RL1, RL2) to move parallel with the advance of the combustion line (2), it is possible to record the path of that combustion line (2). <IMAGE>
