Title: Pulse rate monitor
Inventor: TAUS HERBERT G
IPC: A61B5/024
Filed: 1981-08-17
Abstract: A pulse rate monitor for displaying the heart beat of a subject (12) while exercising comprises a pair of infrared emitters positioned on either side of a thin appendage of the body, such as the septum of the nose or the upper part of an ear (16). The emitter light paths are modulated by changes in the superficial blood volume in these areas, causing corresponding changes in the amount of reflected and transmitted light reaching an infrared detector positioned on one side of the appendage. The emitters are power strobed to provide a pulsed sensor output which is processed by electronic means to provide both analog and digital displays for the subject (12). Also a visual pulse output blinks on and off at the rate of the subject's heartbeat and when high or low adjustable limits are exceeded an audio output warns the subject in time to take corrective measures in his exercise regime. <IMAGE>

Title: A method for the simultaneous production of combustion gas and argillaceous articles
Inventor: HOHMANN HANS
IPC: C04B38/06
Filed: 1982-04-28
Abstract: Argillaceous articles, such as breeze blocks, are produced simultaneously with combustion gas in the same, indirectly heated, closed vessel (A) by placing in the vessel stacks (3) of blocks, each comprising 10 - 60% by mass of a gas-producing constituent such as coal.

Throughout this time an internal pressure in excess of 100 pa is maintained in the vessel by controlling the discharge of gas through pipe 5 by valve 6 and, when valve 6 is closed during cooling, controlling the outflow of cooling medium by valve 7. Gas from the pipe 5 is burnt in the indirect-heating means for the vessel. <IMAGE>
