Title: Melamine purification
IPC: C07D251/62
Filed: 1969-06-18
Abstract: 1,256,178. Melamine purification. ALLIED CHEMICAL CORP. 18 June, 1969 [19 June, 1968], No. 30959/69. Heading C2C. Hydroxytriazine impurities are removed from aqueous ammonia-free solutions of impure melamine by acidifying said solutions to a pH not greater than 7 with an acid having an ionization constant at 25 C. of at least 4À5 x 10<SP>-7</SP> and which forms water soluble salts with melamine, crystallizing and separating the resultant hydroxytriazines from the melamine solution and, if desired, recovering melamine from the solution. The starting solution is preferably that obtained from a melamine synthesis comprising pyrolysis of an aquoammono carbonic acid, alone or with ammonia, quenching the pyrolysis product with water separating a major proportion of melamine from the resulting aqueous ammonia-containing solution and stripping ammonia from the solution. Specified acids are HC1, HNO 3  and, preferably, carbonic acid, introduced as CO 2 . The hydroxytriazines, e.g. ammelide and ammeline, are believed to be released from their highly soluble ammonia addition compounds by addition of acid. The purified melamine solution can be used as the aqueous quench for the pyrolysis product in the above synthesis. The process is illustrated by reference to flow diagrams (not shown).

IPC: B29D30/06
Filed: 1937-11-12
Abstract: 490,806. Removing tyres &c. from moulds. UNITED STATES RUBBER PRODUCTS, Inc. Nov. 12, 1937, No. 31178. Convention date, Nov. 24, 1936. [Class 87 (ii)] In loosening rubber articles such as tyres 10 from mould members 9 moving along as on a conveyer 4, 5, portions of the article projecting from the mould member are subjected to lateral pressure which is progressively increased to deflect the article from the mould member, the pressure being applied over the periphery of the article by rotating the mould. The tyre 10 and lower mould part 9 are carried by the conveyer chains 4, 5 over a frame 1 and between a vertically disposed endless chain 31 and a series of fingers 11 arranged in a line angularly disposed to the conveyer 4, 5. Thus, as the tyre is moved along, the fingers push it into contact with resilient rubber pads 36 carried by the chain 31 and finally engage and successively deflect portions of the tyre from the mould, the tyre and mould being rotated by contact with the pads 36. The fingers 11 are pivoted in brackets 12 carried on posts 16 vertically adjustable in frames 15. The ends of the fingers are rounded so that they adjust themselves to the mould and the pressure of the tyre turns them about the pivots so that they tend to raise the tyre from the mould. The posts 16 are vertically adjusted through gearing 18, 19, 22 from a power-driven shaft 23. The vertical conveyer 31 comprises rollers 32, 33 running on tracks 29, 30 and carries blocks 35 supporting rollers 34 running on a horizontal track 28. The blocks 35 carry the resilient pads 36. The conveyer 31 is driven by gearing from a sprocket drive 45 or it may be driven from the conveyer 4, 5.

Filed: 1971-07-02
Abstract: 1283009 Pipe supports L S SUOZZO 2 July 1971 [9 Oct 1970] 31178/71 Headings F2P and F2S A support for protecting pipes and other equipment against shock loading and/or undesirable vibrations comprises a spring unit S connected through lever L to pipe P in such manner that the pipe is free to move under normal expansion but any shock load is absorbed through the spring unit. In the embodiment shown the pipe P is connected by link 61 to one end of lever L pivoted at 42 and connected at 45 to one end of rod 44 passing through the spring unit S and arranged to have free movement "X" therein. The unit S consists of tubular member 32 with end caps 33, 34 and carrying disc compression springs D 1 , D 2  which act against a partition 30 attached to housing 20. The compression of the springs is set by adjustment of the screw caps 33, 34 on the tube 32. The lever L also carries a cam 48 which co-operates with cam 51 in sliding contact with the end face of cap 33 and connected via bell-crank lever C and link 54 to the opposite end of lever L. In use the device is set with the pipe cold (lever L in position "c", as shown) with the required clearance "X" between the adjustable nuts 47 on the end of rod 44 and the end of cap 34 of the spring unit S As the pipe is heated the lever L moves to the position indicated "h" ( the movement being indicated by pointer 43 on scale 27) and the clearance "X" is taken up by consequential movement of rod 44. The cam 51 is lowered through the link-lever mechanism so that the cam surfaces 50, 52 are in contact. Thus any subsequent shock load on the pipe acts through the lever L directly on to the spring unit S and is transferred through the housing 20 to the support structure 64.

Title: A method of operating a pumping installation and an installation suitable for operation by this method
IPC: F04D13/14
Filed: 1957-10-04
Abstract: 854,626. Centrifugal pumps. SULZER FRIERES S.A. Oct. 4, 1957 [Oct. 6, 1956], No. 31199/57. Class 110 (1). A pumping installation comprises at least two individually startable and stoppable pumps with different delivery-lift characteristic curves disposed in parallel with one another and with their inlets connected to a suction chamber into which a supply conduit leads, the pumps being so designed and their normal operating speeds being such that the projections on to the delivery axis of those parts of adjacent delivery lift characteristic curves relating to the individual pumps and combinations thereof which correspond to the region between the maximum and minimum liquid levels in the suction chamber overlap, and means being provided which, in dependence on the liquid level in the suction chamber, effect an automatic changeover to a pump or combination of pumps having an adjacent characteristic curve. Sewage flows through a conduit 1 to a suction chamber 2, to which are connected the suction pipes 3, 4 of pumps 5, 6. Delivery pipes 7, 8 extend upwardly from the pumps to a collecting tank 9 from which the sewage flows through a pipe 10. The two pumps are run at different speeds or have different blade systems, whereby the curve I of delivery Q against lift H for the pump 5 is different from the corresponding curve II for pump 6. The parts of the curves intercepted between the maximum liquid level A and the minimum liquid level B overlap in respect of the maximum delivery on curve I and the minimum delivery on curve II, as shown at R. Similarly, the curve III for the two pumps in parallel has an overlap 5 with curve II. The overlaps ensure that the delivery range C, P is free from gaps. When the inflow is small, pump 5 operates. If increase of inflow raises the liquid level sufficiently, a float 14 operates a switch 15 to start the pump 6 and stop the pump 5. If a sufficient further increase in liquid level occurs, pump 5 is re-started so that both pumps are then in operation. The reverse sequence occurs when the liquid level falls. To avoid water-hammer in the piping, a starting resistor in each motor circuit ensures that starting and stopping is done gradually. More than two pumps may be used. It is stated to be known to control the pumps by means of throttle valves located in the delivery pipes and operated by a float in the suction chamber.
