Title: Distributor for pneumatic apparatus for filling and exhausting tanks, cesspools and the like
IPC: F16K11/083
Filed: 1922-03-30
Abstract: 177,794. Tamini, M. March 30, 1921, [Convention date]. Valves for pressure fluid, arrangement of; vacuum apparatus.-A single distributor valve for water raising and forcing apparatus of the vacuum and pressure type is contained in a casing leading to the tank by a pipe 5 and controls exhaust to the pump by pipe 4, communication to the atmosphere by pipes 3, 3<1>, fluid pressure supply frcm the air pump by a pipe 1, and communication to a burner for the noxious gases by a pipe 2. The valve is hollow and has three openings 6, 7, 8 in the plane A B, 6, 7 being connected, and four openings in the plane C D, two of which are connected by a pipe 10 as shown in Fig. 3. In the position shown, the pump is exhausting from the tank through pipes 5, 10, 4, and delivering to the burner through pipes 1, 6, 7, 2. By turning the valve anticlockwise 90‹, the tank is connected to atmosphere by pipes 5, 10, 3<1> and exhaust to a lower level can take place. If pressure is necessary to force the contents from the tank the valve is turned clockwise 90‹ from its original position and the pump then draws from atmosphere by pipes 3, 10, 4 and forces it into the tank by pipe 1, openings 8, 11 in the valve, and pipe 5.

Title: Improvements in and relating to bottle filling devices
IPC: B67C3/26
Filed: 1970-02-26
Abstract: 1,263,222. Filling bottles. STORK-JANSEN & SUTORIUS N.V. 26 Feb., 1970 [28 March, 1969], No. 9442/70. Heading B8T. [Also in Division F2] A filling nozzle for filling liquids under pressure, has a valve member (9), Fig. 1 (not shown), in a housing 4 at the lower end of a gas conduit 3. The valve is characterized by having magnetic material arranged at its upper end at (13), Fig. 1 (not shown). In operation needle valve 17 is opened so that gas under pressure passes through pipe 3 forcing the valve member (9), Fig. 1 (not shown), downwards so that the bottle is flushed with gas. Valve 18 then opens permitting liquid to flow down into the bottle. When the liquid level in the bottle reaches the lower end of the housing 4, i.e. hole (8), Fig. 1 (not shown), the valve member (9) is forced up against the lower end of tube 3. After this has occurred the pressure in the bottle rises eventually preventing any more liquid flowing into the bottle, and valve 18 then closes. The vent tube 20 then lowers the pressure in the neck of the bottle to atmospheric pressure, the gas in tube 3 is released since the excess pressure then forces valve member (9) from the bottom of tube 3 and the gas in tube 3 escapes via holes 6 above the liquid level, so that no frothing of the contents of the bottle occurs. The bottle is then removed from the filling head and the filling cycle recommences. The magnetic material on valve (9) reduces the force necessary to lift the valve member into contact with the lower end of tube 3 and prevents the valve member from opening once it has closed unless some pressure differential develops across it.

Title: Polymers derived from phenols and unsaturated acetals
IPC: C08G8/30
Filed: 1959-03-19
Abstract: Condensation polymers are formed from a tris- or tetrakis-pheno and a 3, 9-dialkenyl spirobi (m-dioxane) of the general formula: <FORM:0879419/IV (a)/1> in which R is H, CH3 or Cl and R1 is H or CH3. The unsaturated acetals are formed from pentaerythritol and acrolein or substituted acrolein.  The phenolic starting materials have 3 or 4 phenolic nuclei attached to an aliphatic chain having 1-12 carbon atoms.  The aliphatic chain may be substituted, e.g. with hydroxyl, chlorine or alkyl.  The phenolic nuclei may also contain substituents, e.g. alkyl, aryl, halogen or nitro. Suitable phenols are 1, 1, 3-tris (hydroxyphenyl) propane; 1, 1, 3-tris-(hydroxytolyl) propane; 1, 1, 3-tris (p-hydroxyphenyl) propene-2; 1, 1, 2, 2, tetrakis-(hydroxyphenyl) ethane; 1, 1, 5, 5-tetrakis-(p-hydroxyphenyl) pentane; 1, 1, 6, 6,-tetrakis-(o-hydroxyphenyl-hexane-2-ol.  The condensation reaction is catalysed by acids, e.g. sulphuric, phosphoric, hydrochloric, benzene- or toluene-sulphonic, Lewis acids, e.g. BF3, AlCl3, SnCl4, TiCl4.  Alkyl sulphates, alkane sulphonic acids, and acid phosphates are also useful catalysts.  Reaction is at 130 DEG -160 DEG C. Mixtures of phenolic compounds may be employed.  The resinous products are useful as casting resins.  They may be cured at 70 DEG -180 DEG C.  In Examples 1-4, a mixture of isomers of 1, 1, 3-tris-(hydroxyphenyl) propane was condensed in varying proportions and using different catalysts with 3, 9-divinyl spirobi (m-dioxane). Example 5 uses 3, 9-di-iso-propenylspirobi (m-dioxane) and Example 6, 3, 9-dipropenylspirobi (m-dioxane). Example 7 uses 2-methyl-1, 1, 3-tris-(hydroxyphenyl) propane. Example 8 uses 1, 1, 3-tris-(hydroxyphenyl)-propene-2.  Example 9 uses 1, 1, 3-tris-(hydroxytolyl) propane.  Example 10 uses a mixture of phenol with 1, 1, 3-tris (hydroxyphenyl)-propane.  In Examples 11, 12, and 13 the 3, 9-divinylspirobi (m-dioxane) is condensed respectively with 1, 1, 2, 2-tetrakis- (hydroxyphenyl) ethane; 1, 1, 5, 5-tetrakis-(hydroxyphenyl)-pentane; and 1, 1, 6, 6-tetrakis (hydroxyphenyl)-hexane-2-ol.

Abstract: 769,371. Ram-jets. McDONNELL AIRCRAFT CORPORATION. April 2, 1955, No. 9688/55. Class 110 (3). A ram-jet engine for helicopters has a pair of doors 13 which close the air inlet end of the casing 1 to reduce the drag when the engine is idle. Fuel is supplied through a conduit 7<SP>1</SP> to a nozzle assembly 6 which is supported by struts 4. A member 9 secured to the assembly 6 supports a central transverse member 12 to which the doors 13 are pivoted. The member 9 contains a cylinder in which slides a piston 10 having a piston-rod 11 which is connected to operate the doors through a linkage 16. The cylinder communicates with a fuel passage in the assembly 6 so that the pressure of the fuel pushes the piston to the right (Fig. 2) to hold the doors open. When the fuel pressure drops the pressure of the air on the doors, aided initially by springs 18, closes them. An apertured diaphragm 20 across the passage 19 controls the rate of movement of the piston 10 while the doors are closing to prevent damage. The engine is secured to a helicopter rotor wing by a bracket 2.
