Title: Improvements in or relating to processes of producing alkyl esters of sulphonated monohydroxybenzoic acids
IPC: C07C303/06
Filed: 1947-09-12
Abstract: The C6 to C18 alkyl esters of sulphonated ortho-, meta- or para-mono-hydroxy benzoic acid, wherein the alkyl group is attached to the carboxyl group, are prepared by reacting the corresponding lower alkyl ester with sulphur trioxide in sufficient quantity to at least produce monosulphonation and subjecting the sulphonated product to ester interchange with an aliphatic alcohol having from 6 to 18 carbon atoms in the molecule or mixtures thereof.  By lower alkyl is meant alkyl groups containing from 1 to 5 carbon atoms.  The methyl ester of the hydroxy benzoic acid may be employed and the rate of addition of sulphur trioxide is such that the temperature is kept between 23 DEG  and 125 DEG  C., preferably 90 DEG  to 115 DEG  C.  A mixture of alcohols having an average molecular weight of about 186 may be employed. Salts of the above alkyl esters of sulphonated hydroxy benzoic acids are prepared by neutralizing the acids with an oxide, hydroxide or carbonate of an alkali or alkaline earth metal (including magnesium).  In the examples, alkyl esters of sulphonated ortho hydroxy benzoic acid are prepared by sulphonating methyl salicylate and subjecting the product to alcoholysis with a mixture of alcohols comprising hexyl, octyl, decyl, lauryl, myristyl, cetyl, stearyl and oleyl alcohols.

Title: Improved apparatus for delivering predetermined volumes of liquid
IPC: G01F11/28
Filed: 1946-08-22
Abstract: 644,569. Delivering measured quantities of liquid. LIPKAU, M. A. Aug. 22, 1946, Nos. 25055 and 25056. Convention dates, Sept. 21, 1945. [Class 106(v)] Apparatus for the delivery of measured volumes of liquid comprises a metering receptacle provided with ports at different heights, discharge of liquid being effected by compressed air, and is characterised by the provision of pan-like extensions to the ports for the purpose of separating, towards the end of the delivery operation, a small volume of liquid in the pans from the main bulk of liquid in the metering receptacle, the said small volume of liquid then discharging quickly. As shewn in Fig. 1 a receptacle 1 has secured thereto a tube 4 having ports 5 provided with pans 6. Within the tube 4 is a second tube 7, rotatable by handle 10 and having ports 5' each of which, at a given rotary position of the tube 7, co-operates with an appropriate port 5. Initially a source of vacuum connected at 34 draws liquid from a reservoir connected to inlet 13 through port 14 and fills the receptacle 1, whereon float valve 20 operates to cut off the vacuum source. Rotation of handle 10 closes port 14 and moves cam 32, closing valve 18, and also opens compressed-air inlet valve 10, Fig. 3, filling chambers 21 and 21<SP>1</SP> with compressed air, the chambers 21 and 21' being inter-connected by a one-way valve 22, Fig. 4. Further rotation of the handle brings the upper pair of ports 5, 5<SP>1</SP>, into alignment and at the same time cam 32' opens valve 23 allowing compressed air in chamber 21 to pass via conduits 24, 25, 26, chamber 28 and conduit 27 to receptacle 1, thus driving out the liquid through port 17 and tube 16. At the end of the delivery air is exhausted through conduit 30 and outer duct 31, bubbling through the liquid thus being prevented. Continued rotation of the handle brings the lower pair of ports 5, 5<SP>1</SP> into alignment and opens valve 23<SP>1</SP>, air being then exhausted from chamber 21' and, through valve 22, from chamber 21. An integrating meter, not shewn, is actuated by handle 10 and records the total number of units delivered. The Specification as open to inspection under Sect. 91 also describes a modification, Fig. 5 (Cancelled), comprising valves 41 operated by cams 42. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in and relating to gun mountings for aircraft, particularly aeroplanes
IPC: F41A27/02
Filed: 1935-09-13
Abstract: 604,265. Aircraft gun mountings. NASH, A. F. Sept. 13, 1935, No. 25498. [Class 92 (i), Aircraft guns moved by hydraulic servo mechanisms are prevented from aiming at points on the aircraft itself by a catch 31 which normally establishes a connection between the gun training control 39 and the valve controlling the supply of fluid pressure to the servo mechanism but which can be moved to an inoperative position by means, such as an arm 12, engaging a cam track 11. The cradle of the gun shown is mounted on a bar 5 extending between arms 4, which pivot on brackets of a rotatable ring 2 and carry the gunner's seat. On the bar 5 is pivoted an arm 24 whose position is determined by the arm 12, these two members being interconnected by linkwork 17 ... 21 and gears 14, 15, 16. On the cam bears a roller 25 on a system of links of which one link 28 is pivoted on a slidable carriage 32 and is formed with a notch for the catch 31. The carriage is connected to the control rod 38 of the fluid supply valve, and is slotted for the passage of an arm which is linked to the control 39. Thus when the control is moved the servo mechanism normally operates to train the gun, but if the cam track has caused the arm 24 to contact the roller 25 and the gun is then depressed the arm 28 so pivots that its notch disengages the catch 31 to break the connection between the control 9 and the servo mechanism.

Patent GB-462906-A (GB)
Title: Improvements in the manufacture of oxygenated organic compounds
IPC: C07C27/10
Filed: 1935-09-17
Abstract: <PICT:0462906/IV/1> In the production of oxygen-containing organic compounds, by the partial oxidation of hydrocarbons, the hydrocarbon vapour at a temperature below its decomposition temperature, and under pressure, is mixed with a gas containing free oxygen under pressure and at a temperature and in quantity such that the mixture is at a reaction temperature.  The process may be used for the oxidation of butane, propane, light petroleum distillates, gas oil and the like.  Preferably, a considerable quantity of a diluent such as steam or nitrogen is present, for instance, the volume of the diluent may be 90 to 200 times the volume of the hydrocarbon vapour. The pressure may be 200--1000 lbs. per sq. in.  The products are mainly acetaldehyde, formaldehyde, acetone, methyl alcohol, acetic and other organic acids, and small quantities of propyl and butyl alcohols.  In the apparatus shown, water from a pipe 1 and air from a pipe 5 are led to a mixer 4 and thence by a pipe 7 to a heating coil 8.  Hydrocarbon is supplied by a pipe 11 to a heating coil 12 and thence by a pipe 15 to a pipe 16 where it meets the steam and air from the coil 8 and passes to the reaction chamber 17, the products passing by any one of several pipes 18 to a pipe 20 which supplies cold water; the pipes 18 are so arranged that the reaction time may be controlled by selecting a particular pipe.  The cold mixture passes to a washer 21, uncondensed gases being vented at 23 while the liquid passes through a pressure-release valve 25a to a chamber 26 where the more volatile portions are separated.  In an example, butane is heated to 300 DEG  F. and a steam-air mixture at 750 DEG C., two streams travelling at high velocity, are mixed and passed to the reaction chamber, the reaction time being 1,15 seconds, after which quenching is effected to 300 DEG  F.  Acetaldehyde, methyl alcohol, acetone, and propyl and butyl alcohols pass off as vapours by pipe 27 and water carrying formaldehyde and organic acids pass out by a pipe 31.  In the Specification as open to inspection under Sect. 91, the process is defined as one in which the hydrocarbon is heated from a temperature below its decomposition point to the desired reaction temperature substantially immediately upon contacting with the oxygen.  This subject-matter does not appear in the Specification as accepted.

[Also in Group XXIX] A single-acting, fluid pressure servomotor, particularly for vehicle hydraulic brake systems, has a controlled member, e.g. the spring- loaded diaphragm 32, movable in one direction by pressure in space 44, and a manual control member 60 displaceable in the same direction to close normal communication between an intermediate chamber 78 always connected with space 44, and an exhaust 80, and then open normally closed communication between the intermediate chamber and a pressure source at 40, whereupon the member 32 moves to close the second-mentioned communication and come to a stop in a position corresponding to the manual displacement of the control member, the servomotor including an arrangement whereby the controlled member is moved bodily with the control member during the first stage of its displacement, e.g. through the spring 88 interconnecting between the control and controlled members and which is slightly stronger than the spring 36 loading the controlled member. When brake resistance is felt in the master cylinder 14 by the plunger 26 the spring 88 is compressed to close the normally open exhaust valve 72 leading via 80 and 50 to an atmospheric chamber 46, and open the normally closed inlet valve 70. The driver feels the resistance of the brakes by pressure in chamber 44 acting on the plunger 60. Should air pressure at 40 fail the brakes are manually operated by a control member flange 112 abutting a ported flange 114 on the controlled member. The connection 116 is provided for operating trailer brakes.

Class 64(2) [Also in Group XXIX] A drain valve is secured to the wall 1 of a compressed air reservoir so that unwanted water passes through a strainer 4 into a chamber 7. When the reservoir pressure is high enough, a spring-loaded valve 15 with guiding lugs 16 is forced down to allow the water to flow through a hole 11 into a lower chamber 8. When the pressure drops, the valve 15 rises to close the hole 11 and, when it drops still further, e.g. when the compressed air supply to the reservoir is cut off, a light spring 22 raises an annular diaphragm 6 bearing both an annular plate 10 in which the hole 11 is formed and a housing 9, containing the valve 15 and a water-discharge valve 19. A spring 18 loads both the valves 15, 19 so that at the raised position of the diaphragm 6, the valve 15 is closed but the valve 19 is raised by the housing 9 to allow water to discharge from the lower chamber 8, to atmosphere through a strainer 23. Instead of the spring-loaded valve 19 there may be a discharge valve member secured to the housing 9.
