Title: Improvements in or relating to hydraulic remote-control apparatus
IPC: F15B7/10
Filed: 1949-09-19
Abstract: 661,142. Telemotor systems. ETABLISSEMENTS P. DUCLOS. Sept. 19, 1949. [Oct. 15, 1948] 24068/49. Class 69 (ii). In a hydraulic remote-control system of the type comprising two distinct hydraulic circuits connecting liquid controlling cylinders 1 and 2 of a transmitting station to liquid operated means, such as pistons 12, of a receiver and two conduits 31 each connecting one of the circuits to one end of an auxiliary cylinder 25 connected itself to an auxiliary tank 24 through a check-valve 35 and an intake valve 36 spring-loaded at the pressure which it is desired to provide in both circuits at the mid-position of the system, the auxiliary cylinder 25 is provided with a manually operated piston 32 acting to interrupt the connection from the conduits 31 to the auxiliary cylinder 25 when the piston 32 is returned to the idle position. The control gear 6 meshes with racks 5 formed on the end of the transmitter pistons 3, 4, which latter reciprocate in the cylinders 1, 2 respectively, each cylinder being connected by a conduit 7 to the receiver cylinders 10 whilst the receiver pistons 12 are joined by a rod 13. The apparatus to be controlled is actuated through a servo-motor connected by a lever 14 with the rod 13. Extensions 17 of the conduits 7 which are provided with isolating valves 19 join a common conduit 21 that enables the system to be filled with oil from a reservoir 23 by means of a hand pump 22. Each transmitter piston is also connected by conduit 31 to the cylinder 25 which is connected at the top to the tank 24; the piston 32 in the cylinder 25 is provided with two passages controlled respectively by check-valve 35 and intake valve 36 and is operated by a lever 34 when rod 13 is in the neutral position in order to effect any necessary compensation or balancing of the system due, for example, to the presence of air therein as the result of leakage. The upstroke of piston 32 enables liquid from the top part of the cylinder 25 to flow through check-valve 35, to the underside of the piston 32; the down stroke closes valve 35 and the liquid is forced into both conduits 31 so long as the pressure necessary to open valve 36 has not been reached. In a modification, the ends of the conduits 31 are not sealed by piston 32 but by check valves linked with the piston.

Title: Improvements in the manufacture of carburetted water gas and in carburetters for usetherein
Inventor: WILLIAMS NORMAN HENRY
IPC: C10J1/213
Filed: 1948-09-16
Abstract: 654,281. Carburetting water gas. HUMPHREYS & GLASGOW, Ltd. Sept. 16,1948, No. 24352. [Classes 55 (i) and 55(ii)] ] In the manufacture of carburetted water gas, using heavy oil in an " empty" or checkerless carburetter, unevaporated oil and carbon residues arising in the carburetter during the spraying period are collected in a layer of refractory material or coke within the carburetter, uprun gas being passed in one direction through the layer and back run steam in the other, and, during the blow period, air being passed through the layer in the same direction as the back run steam and, it may be, some blow gases in the same direction as the uprun gas, to maintain the layer at a high temperature, so that oil residues reaching it are evaporated and carbon deposits in it are steamed off or burnt off by the air. The Figure shows the lower part of an "empty" type carburetter to which the invention is applied. A bed 10 of coke is supported on a grate 12 so as to provide a space beneath the grate. Above and below the bed 10, passages 18 and 20, controlled by valves 18a and 20a, connect the carburetter to the superheater. Air can be admitted below grate 12 through a pipe 22. During the uprun, oil is sprayed into the carburetter, valve 18a being closed and 20a open so that the gas make flows downwardly through bed 10 which filters out unevaporated oil and carbon residues. On changing to the back run, steam passes in through pipe 20 and up through bed 10, evaporating the oil therein and gasifying some or all of the carbon. During at least part of the blow period air is admitted below the grate, valve 20a being closed and 18a open, so that it flows up through bed 10, burning off the remaining carbon therein and raising the bed to a high temperature for the next uprun.
