Title: Method of treating wood
IPC: B27K3/52
Filed: 1970-11-23
Abstract: 1377061 Impregnating wood RENTOKIL Ltd 23 Nov 1971 [23 Nov 1970] 55694/70 Heading DIP A process for the chemical treatment of wood e.g. in the form of timber, plywood or chipboard, comprises a first stage in which the wood is impregnated in a treatment vessel with a solution of a treatment agent in at least one halogenated hydrocarbon solvent which is inert to the agent, the solution being forced into the wood by a pressure differential, and a second stage in which, after removal of excess solution, the solvent remaining in the wood is removed therefrom by passing heated air through the vessel so as to cause evaporation of the solvent, the solvent being recovered. The solvent may be dichloromethane, trichloroethylene, perchloroethylene or fluorotrichloromethane. The impregnant may be phosphorus oxychloride, a boric or phosphoric acid ester, a wax or a film forming resin or a mixture of these. Solvent evaporation may be assisted by reducing the pressure in the vessel. The bulk of the evaporated solvent may be recovered by cooling or pressurising and cooling. The remainder may be removed by absorption on carbon followed by steam stripping and condensation. The process may be a full or empty cell process e.g. a Bethell, Rueping or Lowry process, or a double vacuum process. In Fig. 1 a piece of wood &c in a treatment vessel 2 is impregnated with solution previously run in from a tank 3 through a valve V4, under pressure provided a pump 4 connected through a valve V6 to a calibrated tank 5 which registers the gross uptake of solution. After removal of excess solution by a pump 6 back to the tank 3, air is circulated by a pump 7 through a heater 8 and the vessel 2 and evaporates solvent from the wood. The solvent vapour is collected in a condenser 9 and the condensed liquid run through a valve V9 into a tank 10 where it is admixed with further treatment agent prior to being returned to the tank 3. The level in the calibrated tank is returned to a desired point by regulating valve V7. In Fig. 2 wood &c 1 in a vessel 2 is impregnated with treatment solution by applying a pressure to the solution in a tank 3 which forces the solution into the vessel through a valve V11, air being vented through a valve V12. After impregnation, the compression is released and the solution is allowed to run back into the tank. Heated air is circulated through the vessel by a pump 7 and solvent is condensed at 9. Further solvent is removed by passing fresh air through the vessel via valve 14 and into a carbon recovery plant 11. The pressures applied during impregnation may be 10 or 20 p.s.i.g. The air may be at about 60‹C and 22‹C on leaving the heater and condenser respectively.

Abstract: 1333604 Automatic compressed air systems; systems responsive to load COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE 18 Dec 1970 [19 Dec 1969] 60326/70 Heading F2F  A railway vehicle braking arrangement includes a pressure transformer relay 1, a support 2 and a differential relay 3 and is responsive to the load on the vehicle, a pressure proportional to the load being delivered to a chamber 24 where it acts on a piston 26 to move a carriage 22 to the right against a spring 23 to change the ratio of lengths of arms of a two armed lever 20 pivotable about a pivot 21 and thereby alter the relative movement of an action rod 7 and a hollow reaction rod 9. A conduit 44 from a source of fluid pressure is connected to chambers 13 and 29 of the relays 1 and 3 respectively. In actuation pressure P from a braking distributer is fed into a chamber 16 of the relay 1 and into a chamber 35 of the differential relay 3: the pressure P is proportional to the brake application pressure drop in a brake pipe. The relay 1 then delivers to a chamber 36 of the relay 3 a pressure R which is some proportion or multiple of the pressure P as determined by the ratio of the lengths of the arms of the lever 20. The pressure R acts on a diaphragm 33 and the pressure P acts on diaphragms 32, 33 and the ratio of the areas of the diaphragm is chosen so that valves 27, 28 are actuated to cause delivery of a pressure from the relay 3 to a brake cylinder 4 through a feed pipe 5, and this pressure will vary in accordance with the pressure P delivered from the distributer and the pressure R delivered from the relay 1. As shown the relay 1 comprises valves 10, 12 actuable by movement of the reaction rod 9. It may include an effective area reaction diaphragm which varies according to the load and in this case the chambers 13 and 16 are fed simultaneously with the pressure from the braking distributer. The chambers 13, 16, 29 may also be fed simultaneously from a distributer in the form of a manual control valve. Time lag devices in the form of throttles or valves are inserted in the pipes 42 and 46.
