Patent GB-1560092-A (GB)
Title: International combustion engines
IPC: F02D41/12
Filed: 1976-07-05
Abstract: In order to retard the closing movement of the throttle valve (2) without significantly impairing the running of the engine, this closing movement is controlled as a function of the vacuum upstream and downstream of the throttle valve (2). In doing this, an air feed device automatically feeds additional air to the feed duct (1) downstream of the throttle valve (2) when the vacuum there falls sharply. This device has an additional air inlet (18) arranged downstream of the throttle valve (2), which inlet is connected by way of an inlet line (19) to a control valve (20) preloaded in the closing position. The latter is designed so that in the event of a sharp increase of the vacuum on the inlet (18) it rapidly opens in order to immediately counteract this increase by an additional air feed. <IMAGE>

Title: Process of and apparatus for effecting continuous digestion in the extraction of cellulose
IPC: D21C3/24
Filed: 1929-09-20
Abstract: 333,426. Holmes, J., and Kingcome, H. A. Sept. 20, 1929. Pulp, preparation of. - In a, process for the continuous digestion of fibrous vegetable material for the extraction of cellulose, the material is subjected to a graduated treatment whereby the more easily hydrolyzable constituents are eliminated first and the more highly resistant lignone treated with clean cooking liquor at the desired maximum temperature for a final digestion, the resultant cellulose being subjected to a countercurrent washing operation before being discharged' from the apparatus. The material is fed by a conveyer A to a mechanical conveyer B which passes it through the apparatus as indicated by the arrows. The material first passes through boiling water zones a, band c, d a vacuum head V being maintained corresponding to these two columns. A column of treatment liquor e, f is maintained in the vertical member J. The vapour pressure in the head S added to the pressure of the column e, f gives a higher pressure in the vapour head T, the vapour of which extends from f to g. Liquor is maintained in the vertical members L, N between the levels g, k, the desired maximum digestion pressure being thus obtained in the horizontal member M. Heating of the member M is effected by a steam jacket. The condensate may be used to heat the vertical members for the water treatment to further extract heat, the final condensate being admitted at m as wash-water. The discharged material passes out of the apparatus at R. A simpler apparatus omitting the vacuum treatment may be used for esparto grass. Pumps connected by pipes at suitable points in the apparatus may be used to circulate the cooking liquors and washwater and to agitate the material.
