Abstract: 346,329. Fluid pressure brakes. CLAYTON DEWANDRE CO., Ltd., FAGARD, J., and EDGE, S. H., Titanic Works, Lincoln. Oct. 8, 1929, No. 30514. [Class 103 (i).] Relates to a vacuum control valve comprising a vacuum sleeve valve V providing a seating for an atmospheric disc valve j on which operating means act directly to close it, continued movement of which opens the vacuum valve V, the valve j being connected to the brake pedal on which a reaction is applied by the action of differential pressures on the collected valves which form a piston. A non- elastic connection is provided between the disc valve and the pedal, including means adapted, with response of the brakes to movement of the pedal, to reclose the valve affected by such movement. This connection comprises a floating lever to the ends of which the valve operating stem and the pedal are connected, a rod from the brakes being connected intermediately. The forward movement of the brake rod when the brakes are applied by the brake cylinder operates the floating lever to reclose the vacuum valve and maintain a desired braking pressure. Opening of the vacuum valve does not require the overcoming of resistance due to pressure difference at opposite sides of the vacuum port. The vacuum valve V is adapted to seat on a shoulder b<1> at the end of a portion a<4> of the valve casing having a reduced internal diameter, and thus close the space b connected by a branch c<1> to the engine induction pipe. In release position when the valve j is open the branch c connected to the brake cylinders is open to atmosphere, past this valve, through the interior of the valve V, and through holes e<1> in the end-plate of the valve casing. The valves are opened against springs d, k. A dust filter e<3> and a protective cover e<2> are provided. A stop abuts the lever in release position. This construction is stated to be suitable for commercial vehicles. Another construction is shown stated to be suitable for pleasure cars in which the valve is controlled by Bowden wire operated by a pivoted pad on the brake pedal which operates the brakes directly.

Title: Improvements in or relating to a method of recovering unconverted ammonia in the production of hydrogen cyanide
IPC: C01C3/02
Filed: 1952-12-05
Abstract: In the production of hydrogen cyanide by interacting gaseous ammonia, a gaseous hydrocarbon, and a gas comprising free oxygen over a platinum metal catalyst, unreacted ammonia is removed from the gaseous mixture leaving the catalyst by passing said mixture through a column containing "acidic silica gel" to absorb the ammonia and then recovered preferably by passing a stream of air through the gel which is heated to a temperature of 175 to 200 DEG C. The "acidic silica gel" is silicic acid anhydride which contains at least 99 per cent of silica calculated as SiO2.  Other methods of removing the ammonia from the gel may be used, such as by passing heated air, superheated steam or other heated inert gas through the column.  The ammonia thus liberated may be absorbed in water, stripped from the water solution, and then compressed ready for further production of hydrogen cyanide.  Specification 361,004 is referred to.
