Title: Governors for internal combustion engines
Inventor: GOLDSMITH CHARLES NORMAN
IPC: F02D1/06
Filed: 1959-03-11
Abstract: 883,135. Engine stop-gear. C.A.V. Ltd. March 2, 1960 [March 11, 1959], No. 8421/59. Class 122 (4). A safety device to prevent reverse rotation of a compression-ignition internal-combustion engine supplied with fuel by a pump 9 controlled by a suction governor comprising a spring-loaded diaphragm 7 connected to the pump output control member 8 and dividing a chamber 4 into two separate compartments 5, 6, one, 5, of which is connected to a point in the engine air-intake system, comprises a valve 15 which, during normal operation of the engine, connects the other compartment 6 to atmosphere but also communicates with a further point in the intake system and is operable in the event of the engine starting to rotate in the reverse direction, thereby causing a positive pressure in the intake system, to close the communication to atmosphere and connect the compartment 6 to the intake system to thus move the diaphragm so that it shuts off the supply of fuel to the engine. The valve 15 (Fig. 2), comprises an inlet 16a connected to the compartment 6 and an outlet 16f connected to the air manifold 13 which, during normal engine running, is at a higher pressure than the point in the intake system to which the pipe 11 from the compartment 5 is connected. During normal running of the engine a diaphragm 18 in the valve 15 is held by the vacuum in the manifold 13 against a seating 16e and the compartment 6 is open to atmosphere through a filter 17 and an outlet 16d, the member 8 then being controlled by the suction in the air inlet pipe 12 in the known manner. If the engine starts to rotate in the reverse direction the consequential positive pressure in the air manifold 13 moves the diaphragm away from the seating 16e and against a seating 16g, thus closing the outlet 16d and opening the compartment 6 through a groove 16i, a hole in the diaphragm, and a passage 16h to the positive pressure in the manifold. The diaphragm 7 is thereby moved to the left to interrupt the supply of fuel to the engine. In a modification of the valve, Fig. 3 (not shown), the seating 16e is omitted and a spring-loaded non-return ball valve contacts a seating in the outlet 16f.

Patent GB-589984-A (GB)
Title: Improvements in the stabilization of cellulose ethers
IPC: C08B11/20
Filed: 1945-04-06
Abstract: A process for the stabilization of cellulose ethers comprises dissolving the cellulose ether in a solvent liquid consisting of or comprising a polar solvent and free from substances having a degrading action on the ether, agitating the solution for at least three hours and then precipitating the ether by means of a liquid which is a non-solvent therefor but is a solvent for the liquid used to dissolve the ether.  Preferably, the cellulose ether solution is stirred from 3 to 24 hours prior to precipitation and the precipitated ether is allowed to remain in the liquid for 1 to 12 hours before it is separated, washed and dried.  Polar solvents specified are alcohol, pyridine and acetic acid.  Solvent mixtures may be benzene and ethyl alcohol (10-50 per cent or more by weight) or ethylene dichloride and ethyl alcohol (5-25 per cent by weight). Suitable precipitants are pentane, naphtha (B.P. 100-150 DEG  C.), gasoline (B.P. 50-150 DEG  C.) and water.  In one example, 20 parts by weight ethyl cellulose of about 45 per cent ethoxy value dissolved in about 200 parts by weight of a solvent mixture (92 per cent ethylene dichloride and 8 per cent of 95 per cent ethyl alcohol by weight) is agitated for 24 hours and the ethyl cellulose precipitated by slowly pouring the solution into high-flash naphtha (B.P. 100-150 DEG  C.).  After standing for 24 hours, the ethyl cellulose is separated, washed and dried.  The ethyl cellulose thus prepared has improved heat resistance.

Title: Process for the production of melamine from urea
IPC: B01J6/00
Filed: 1963-03-05
Abstract: Melamine is made from urea by a process which comprises continuously introducing molten urea into the bottom of a vertically arranged heated zone in a reactor, said heated zone being produced and maintained at at least 350 DEG  C., preferably 375 DEG  to 450 DEG C., by heaters within the said vessel, directing said urea into intimate contact with a hot molten mixture comprising melamine, unreacted urea and reaction by-products, whereby said urea is caused to pyrolyse to melamine and gases are produced which, with the aid of the thermal lift in said heating zone, cause the reaction mixture to circulate upward in said heated zone with continued pyrolysis of the urea, removing part of the melamine and gaseous by-products from the upper portion of said reaction vessel, causing recirculation of the remaining part within said vessel to the lower portion of said vessel by downward thermal flow produced by establishing a relatively cooler zone in said reaction vessel, and maintaining the pressure at at least 1000 p.s.i.g. (70 kg./cm.2) and preferably at 1500 to 3000 p.s.i.g. (105 to 210 kg./cm.2).  During any interruption of urea feed, ammonia gas is fed into the reactor into the bottom of the heated zone to maintain circulation.  Prior to commencement of the urea feed, the reactor is fed with hot water and heated to 350 DEG C. at 3500 p.s.i.g. (245 kg./cm.2) and then the water is drained and the reactor is then preferably purged with ammonia. The invention is described with reference to a drawing of (not shown) an apparatus which is the subject matter of Specification 1,033,027. Reference is made to Specification 735,356.
