Title: Improvements in or relating to processes for performing chemical reactions
IPC: B01J8/02
Filed: 1931-09-24
Abstract: In exothermic reactions involving organic compounds, e.g. the oxidation of alcohol to acetaldehyde, the reaction zone, which may consist of a catalyst bed, exchanges heat with a climbing film of cooling liquid which is supplied at such a rate that its evaporation effects or aids the formation of the climbing film. The climbing film is preferably vertical, and the heat withdrawn from the reaction zone may be employed to preheat the incoming reactants, or to vaporize the alcohol.  The hot reaction products may also serve to heat the liquid within the heat-exchanging elements and augment or even effect the motion of the film of evaporating liquid.  The heat exchanging elements may consist of vertical tubes or of two concentric tubes, the vapour leaving by means of the inner tube.  In the arrangement shown in Fig. 1, the heat exchanging elements consist of concentric tubes 6, 8, the liquid being fed to the other tube 6 from the inlet 13, and maintained at a suitable level by the sight glass 11.  The reaction gases enter by the pipe 4, pass through the catalyst layer 3 and the reaction products are withdrawn by the exit pipe 5.  The liquid in the outer tube 6 is maintained boiling by the heat of the reaction and climbs upwards as a film, the vapour generated passing out through the tube 8.  The liquid should have a boiling point considerably lower than the reaction temperature. Water is a preferred liquid.  Specification 390,504 is referred to.ALSO:<PICT:0390186/III/1> In a process for controlling exothermic chemical reactions, the reaction zone, which may consist of a catalyst bed, exchanges heat with a climbing film of cooling liquid which is supplied at such a rate that its evaporation effects or aids the formation of the climbing film.

Title: Anti-Skid Device for a Vehicle Braking System

Filed: 1968-06-06
Abstract: 1,191,216. Aritiskid braking systems. SOC. ANON D.B.A. 6 June, 1968 [22 June, 1967], No. 26961/68. Heading F2F. [Also in Division G3] An antiskid device for vehicle braking systems comprises an electronic sensing unit and an actuating unit for decreasing or cancelling the pressure in the braking system. The electronic sensing unit comprises a speed sensing device, such as a tachometer generator or a variable frequency generator with a detector, giving a signal voltage V proportional to the speed of the vehicle; a differentiating circuit providing a signal γ proportional to the acceleration; and a device, such as a Schmitt trigger, which produces an output signal D while the deceleration is greater than a predetermined value. The signal D is applied to electromagnetic valves to reduce the pressure in the braking system. The above system delays but may not fully prevent wheel locking; a modified system (Figs. 3, 4, not shown) prevents wheel locking until the vehicle stops. In this both the acceleration signal y and the output D of the Schmitt trigger are differentiated and applied to the two inputs of a bi-stable multivibrator. This provides a control signal for the valves which continues until point C on the speed curve when the vehicle is again moving at constant speed.
