Title: Control mechanism for a variable discharge pump
IPC: F15B9/08
Filed: 1973-06-01
Abstract: 1433146 Rotary positive-displacement  machines ROBERT BOSCH GmbH 1 June 1973 [22 June 1972] 26391/73 Heading F1F A control mechanism for a variable-discharge pump 11 of the vane-type wherein an adjustable stator in the form of a ring 14 is movable by pistons 17, 18 operated by a control valve 24, comprises a rigid transmission lever 38 pivotally connected to piston 17 and valve member 26 and a bell crank lever 44 having one arm which is forked at 45 to co-operate with a pin 42 on lever 38, the other arm having a rounded part 46 acted upon by spring- loaded tappets 47, 48, the lever 44 being rigidly mounted on a shaft 43 to which is also rigidly connected an operating lever 50. The discharge line 32 of the pump communicates with a line 28 connecting an annular recess 27 of valve chamber 25 with the chamber 21 of piston 18. The chamber 20 is connected by line 23 to chamber 25 and a further annular recess 29 of chamber 25 is connected to reservoir 31. In use, if lever 50 is moved anti-clockwise about shaft 43 then, since the fulcrum A of lever 38 is its pivotal connection 39 to rod 40, the lever 38 will move clockwise and thus move valve member 26 to the right. This causes the discharge pressure in line 28 to be connected to chamber 20 and since the effective area of piston 17 is greater than that of piston 18, the ring 14 will move to the right to alter the discharge of the pump. This movement of piston 17 will tend to move lever 38 in an anti-clockwise direction about a fulcrum C provided by pin 42, thus restoring the valve member to its initial position. The spring tappet 47 which was initially com-  pressed by the anti-clockwise movement of arm 44 now acts on arm 44 to move clockwise back to its original position thus moving lever 38 about fulcrum B, the piston 17 being correspondingly moved back so that the ring 14 is returned to its former location. Movement of lever 50 clockwise from the neutral position moves valve member 26 leftwards to connect chamber 20 to reservoir 31 so that piston 18 moves ring 14 to the left. In this case tappet 48 is compressed and performs the restoring function. Further embodiments are described Figs. 5 to 10 (not shown).

Title: Film evaporator having an improved feeding means
IPC: B01D1/22
Filed: 1953-09-30
Abstract: <PICT:0748307/III/1> A film evaporator of the type which has a cylindrical evaporating surface disposed in a vertical position is provided with a liquid feeding means comprising an annular compartment which is rotated inside the upper end of the heated cylinder, said compartment being bounded above and below by two horizontal flanges which extend closely adjacent to the inner surface of the cylinder and being supplied with liquid through an inlet which discharges into the open side of the compartment.  The liquid flows from the compartment into the evaporator proper through the gap between the lower flange and the inner surface of the cylinder.  The feeding means obviate the foaming of liquids, for instance glues, particularly when the evaporation is carried out in vacuo.  In the Fig. the anular compartment 1 which is bounded by flanges 16 and 17 is U-shaped; it is connected to shaft 2 by spokes 19.  A circular projection 4 is provided in the compartment, dividing it into an upper chamber 7 and a lower chamber 13.  The evaporating surface 5 is heated by jacket 9; and the evaporator is maintained at subatmospheric pressure.  Liquid is introduced through pipes 3 into chamber 13.  The sudden drop in pressure and the heated surface cause flash-evaporization of part of the entering liquid; but projection 4 prevents liquid droplets being carried upwards in the rising vapours. Some of the vapour passes up through openings 8 in flange 17, and the remainder passes up through gap 18 between flange 17 and surface 5. The liquid flows downwards through gap 6 between flange 16 and surface 5 into the interior of the main evaporator 15.  The vapours formed therein flow upwards through spokes 19.  The united vapours leaving the top of the evaporator pass to a condenser (not shown). An embodiment is described wherein a ring and brush device is provided for the separation of entrained liquid from the vajour generated in the main evaporator.

Title: Improvements in and relating to the production of cyclo-olefines
Inventor: REED HUGH WILMA BOULTON
IPC: C07C2/46
Filed: 1951-11-19
Abstract: Cyclo-olefins containing 8 carbon atoms in the ring, and also those containing 12 and 16, are produced by heating a conjugated diolefin with a catalyst derived from nickel carbonyl by replacing at least 1 CO group with an organic phosphite. Preferred catalysts have the formula [(RO)3P]xNi(CO)4-x, where R is an alkyl, aryl or other hydrocarbon radical and X is 1 or 2, and particularly [(RO)3P]2Ni(CO)2, where R is phenyl or methyl. They are prepared by bringing together nickel carbonyl and, for example, triphenyl phosphite in the requisite proportions, suitably in ether as solvent. Acetylene may be present during the polymerization reaction when conditions may be as described in Specification 701,106.  When acetylene is absent, the diolefin may be added to the solvent and catalyst and heated to 100-130 DEG  C. for 40-100 hours. Cyclo-octa-1,5-diene of high purity is produced, together with 4-vinylcyclohex-1-ene.  With acetylene, compounds derived from this and the diolefin, as well as cyclic trimers and tetramers of the diolefin are also present in the product from which C12 and C16 fractions may be separated.  In examples, butadiene is heated under pressure with bis(triphenyl or trimethyl phosphite) nickel dicarbonyl, and benzene as solvent.  Acetylene is, in some cases, added, either at intervals or only at the beginning of the reaction, while 2,5-ditertiary butyl quinone may be present as an inhibitor of polymerization.ALSO:Catalysts for producing cyclo-olefins from diolefins are derived from nickel carbonyl by replacing at least 1 CO group with an organic phosphite.  Preferred catalysts have the formula [(RO)3P]x Ni(CO)4-x, where R is an alkyl, aryl or other hydrocarbon radical and x is 1 or 2, and particularly [(RO)3P]2Ni(CO)2, where R is phenyl or methyl. They may be prepared by bringing together nickel carbonyl and, for example, triphenyl phosphite in requisite proportions.  Ether may be present as a solvent and removed afterwards by distillation.
