Title: Hydraulic torque converter
Inventor: DUNDORE MARVIN WALTER
IPC: F16H41/26
Filed: 1959-09-10
Abstract: 881,296. Hydraulic torque converters. TWIN DISC CLUTCH CO. Sept. 10, 1959, No. 30965/59. Class 69 (2). An hydraulic torque converter comprises a bladed impeller 55, turbine 56, and first and second stator members 57, 58, the impeller and second stator being located in the outward flow part of the toroidal liquid circuit with the outlet of the second stator blades disposed closely adjacent the inlets of the impeller blades, the turbine and first stator being located in the inward flow part of the circuit with the outlets of the turbine blades disposed closely adjacent the inlets of the first stator blades, and the outlet of the impeller and the inlet of the turbine and the outlet of the first stator and the inlet of the second stator being respectively connected by U-shaped unbladed passages 59, 60. Both the first and second stators may be secured to a stationary sleeve, or the second stator be secured to a stationary sleeve 62 and the first stator be secured to a sleeve 66 which is connected to the ring gear 70 of a differential gear unit 65 having planet gears 71 carried by a stationary member 64 to which the sleeve 62 is secured. The planet gears 71 engage a sun-gear 73 connected by a freewheel device 74 to the output shaft 61 of the converter. The ring gear 70 is adapted to be held by a brake 75 against rotation at a predetermined ratio between the speeds of the input and output shafts by the action of a governor, such as described in Specification 865,570, to lengthen the efficient working range of the converter. The first stator thus either rotates in the opposite direction to the turbine when the brake is disengaged or, when the brake is engaged, is held stationary. In an alternative arrangement, the turbine is connected to the ring gear 70 and the first stator connected to the sun-gear 73. Where the speed ratio of the converter is at, or slightly below, 1:1, the impeller and turbine may be locked together by means of a friction clutch or an overrunning or freewheel clutch, such a clutch permitting starting of an engine driving the converter. The fluid used in the converter may be circulated through an external cooler. The Specification includes details relating to the inlet and outlet angles and configurations of the blades, the shape of the U-shaped passages, and the shape of the passages between the rings supporting the blades; the passages between the rings supporting the impeller and turbine blades converge and diverge, respectively, in the direction of fluid flow to compensate for the varying distances between the blades with changes in radices from the axis of the converter and to prevent turbulent flow through the toroidal circuit.

Title: Process for converting unsaturated aldehydes or unsaturated ketones to olefinically unsaturated alcohols or amines
Filed: 1953-11-09
Abstract: Olefinically unsaturated alcohols or amines are produced by heating an unsaturated aldehyde or ketone with anthracene or an alkyl derivative thereof to form a Diels-Alder adduct, reducing said adduct either alone or in the presence of ammonia or a primary or secondary amine, and pyrolysing the resulting product to yield the desired olefinically unsaturated alcohol or amine and to regenerate the anthracene or alkyl derivative thereof.  The aldehyde or ketone used may contain either olefinic or acetylenic unsaturation.  Acrolein and methyl acrolein are suitable, giving allyl alcohol and methallyl alcohol respectively.  The formation of the adduct may be effected at temperatures of 50-400 DEG  C., preferably 150-200 DEG  C., and at a pressure of at least 35 kilograms per sq. cm., e.g. 70-200 kilograms per sq. cm. Solvents such as hydrocarbons or alcohols may be used and a reaction time between 0.5 and 3 hours is generally suitable.  The reduction is preferably effected by catalytic hydrogenation in liquid phase using Raney nickel, copperchromium oxide or a catalyst comprising Fe, Co, Cu, Pd, Zr, Ti, Th, V, Pt, Ag, Mo, Al or compounds thereof, which may be used as such or supported on a carrier.  With Raney Ni, pressures between 35 and 350 kilograms per sq. cm., temperatures of 30 DEG  to 150 DEG  C. and reaction times between 0.5 and 8 hours are suitable.  The reduction may also be effected electrolytically or by treatment with sodium or sodium amalgam in water or alcohol, or with aluminium isopropylate in isopropanol. Zinc-copper or aluminium-mercury alloys may also be used.  The pyrolysis is effected at temperatures between 250 DEG  and 400 DEG C. for between 2 and 60 minutes at normal or superatmospheric pressures.  In examples (1), (3) and (4), an anthracene adduct of acrolein is formed (characterized by forming the 2,4-dinitrophenylhydrazone), the adduct is hydrogenated using a Raney nickel catalyst and the product pyrolysed to give allyl alcohol; (2) an acrolein-anthracene adduct is hydrogenated in the presence of liquid ammonia, the hydrochloride of the product formed and converted to the free amine adduct which on pyrolysis gives allylamine; (5) and (6) the procedure of (3) is followed using 2-methyl anthracene and 9,10-dimethyl anthracene respectively instead of anthracene.

Title: Apparatus for evaporation of liquids
IPC: F28F1/28
Filed: 1966-07-12
Abstract: 1,101,868. Evaporators wherein liquid flows through channels formed by nested heatconducting frustated cones. ALFA - LAVAL AKTIEBOLAG. 12, July, 1966 [12 July, 1965], No. 31165/66. Heading BIB. In an evaporator, suitable for the concentration of milk and juices, comprising a series of heat-conducting truncated cones 1, 2 nested together one within the other in spaced relationship to define alternate channels for the flow of liquid to be evaporated (channels 11) and for the heating medium (channels 10) respectively, wherein the liquid and the heating medium are introduced into their respective channels at the larger periphery, and the boiling liquid and vapour is discharged from the liquid channels at the smaller periphery, and the heating medium is introduced into the channels 10 at their larger periphery, the apex angle or shape of the cones is such that the distance between them in the liquid channels 11 increases from the larger periphery to the smaller in order to accommodate the formation of vapour and to provide decreasing heating surface in the direction of flow of liquid. As shown, alternate cones are of different apex angle, but the increase in cross-section of the liquid channels may also be achieved by employing step-shaped truncated cones. The cones are assembled in housing 13 by means of spacers between the flanges on the peripheries of the truncated cones. The heating medium, e.g. steam, is introduced into the housing through inlet 18, and passes through openings (not shown) between spacers 7 into channels 10, which are closed at the top. The steam condensate flows down channels 10, and is withdrawn from the housing through outlet 19. The liquid to be evaporated is supplied through conduit 20, and flows up through a channel 21 formed by a boring through the housing, the spacers and the flanges of the cones. From channel 21, the liquid flows through radial passages 22 in spacers to liquid channels 11. The mixture of concentrated liquid and vapour is discharged from the upper ends of channels 11 into chamber 24, where the vapour separates from the liquid. The vapour leaves the housing through outlet 25; and the concentrated liquid is withdrawn through outlet 26. Non-condensible gases are removed from channels 10 via tubes 28, channel 29 and conduit 30.

Title: Improvements in or relating to liquid liquid chromatography
Inventor: SCOTT RAYMOND PETER WILLIAM
IPC: G01N30/80
Filed: 1962-08-15
Abstract: 998,107. Partition chromatography detection systems. PYE Ltd. Aug. 7, 1963 [Aug. 15, 1962], No. 31246/62. Heading B1X. A liquid-liquid chromatographic apparatus comprises a solid body adapted to carry away as a surface film, a sample of the effluent from the chromatographic column first past means to vaporize the solvent, and then past a heater to pyrolize the soulte, and means to pass the pyrolysis products to a detector. In a specific embodiment, Fig. 1, glass tube 1 has inlet 2 for argon, and outlets 3 and 4, the outlet 4 being to a flame ionization or argon detector. A portion of the eluate from column 5 is deposited on wire 7, e.g. an iron wire coated with glass fibres, the wire being passed from feed spool 8 to take-up spool 9. H.F. heater coils 10 and 11 remove the solvent and pyrolyse the solute, respectively. The solvent vapour is carried away through 3 while the pyrolysis products pass through 4 to the detector. In a modification, Fig. 2 (not shown), a wire, e.g. of Pt on the end of a dipper, is dipped into the eluate and then raised through two heating zones in a vertical tube. The first heating zone volatilizes the solvent while the second pyrolyses the solute. A flow of argon entering the tube between the two heating zones causes the solvent vapour to be swept downwards whilst the pyrolysis products are swept upwards to an argon detector. The Provisional Specification describes the use of a band in place of the wire and a flame to clean the wire before receiving the portion of eluate. The pyrolysis of the solute takes place in the ionization chamber. Specification 921,215 is referred to.
