Title: Improvements in multiple-expansion reciprocating engines
IPC: F01K7/02
Filed: 1931-12-24
Abstract: 382,465. Steam engines. AKTIEBOLAGET GOTAVERKEN, and JOHANSSON, J. E., 25, Olivedalsgatan, both in Gothenburg, Sweden. Dec. 24, 1931, No. 35739. [Class 122 (iii).] In a multiple expansion engine, the exhaust from any one of the cylinders is compressed in a single-stage compresser driven by a turbine driven by the low-pressure cylinder exhaust, and is fed to the inlet or the receiver of the same cylinder. In compressing the low-pressure exhaust steam, a turbo-compresser is used ; in compressing the intermediate pressure cylinder exhaust, a reciprocating-pump, driven through gearing from the turbine, is used. The compressed steam may be superheated. In the construction shown in the Figure, the turbine 8 operates the compresser 12 which takes lowpressure steam from the cylinder 4 through pipe 14 and passes it through pipe 15 to the lowpressure inlet. The turbine may be put out of action and the low-pressure exhaust passed to the condenser 10. The compresser may be fed with steam at the pressure of the exhaust lead which is led past a non-return valve 24 into a container 25, or the steam may be drawn off through a positively-actuated valve from the low-pressure cylinder during expansion; a container similar to the container 25 may be used. Feedwater may be heated in stages by steam tapped through branches 20, 21, 22. In a modification, a geared reciprocating-pump passes steam from the intermediate pressure exhaust through a superheater to the intermediate supply.

Title: Improvements in or relating to a process for making vanillin and the product resulting therefrom
IPC: C07C47/58
Filed: 1937-12-28
Abstract: A substantially water immiscible alcohol, e.g. normal or secondary butyl or amyl alcohol, cyclohexanol, or benzyl alcohol is used to extract vanillin from a liquor, e.g. an alkaline liquor containing it.  The vanillin containing liquor is preferably obtained by cooking preferably under pressure with water and an alkali metal hydroxide, ligno-cellulose, crude lignin extract or a lignin-sulphonic acid compound, e.g. as described in U.S.A. Specification 2,057,117.  Since the vanillin is extracted from alkaline liquors not corrosive to iron less expensive apparatus may be used than when handling acid solutions.  The vanillin may be obtained from the calcium salt of ligninsulphonic acid obtained from waste sulphite liquor by the process described in U.S.A.  Specification 1,856,558 or Reissue Specification 18268, the salt being treated with sodium hydroxide, carbonate, sulphite or sulphate to convert it to the sodium salt, calcium salts being removed.  Excess sodium hydroxide, e.g. 25 per cent of the weight of the lignin substance is then added and the solution is heated for 1/2 -1\ba1/2 hours under a pressure of 9-14 kgm.-sq. cm.  The alkaline solution is then extracted with normal butyl alcohol, e.g. by shaking or stirring the liquids together or by passing them in countercurrent through extraction towers or by spraying the solvent through the liquor in tanks, the separated solvent being withdrawn from the top of one tank and sprayed into the bottom of the next.  The vanillin may be extracted from the separated alcoholic layer by distilling off the alcohol, completing the distillation in steam to yield aqueous sodium vanillate which is treated with sulphur dioxide, filtered, and acidified with sulphuric acid to yield vanillin which is purified by recrystallization, distillation or solution in a solvent from which it may be extracted as its bisulphite addition product. Butyl alcohol may be recovered from the aqueous layer after extraction by distillation.

Title: Braking arrangement
Inventor: MCNULTY JOHN F
IPC: F16D63/00
Filed: 1964-09-02
Abstract: 1,063,445. Electromagnetic brakes. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 2, 1964, No. 35925/64. Heading F2E. [Also in Division H2] A magnetic brake comprises a brake member, core, and a pair of windings on said core having opposite magnetic effects thereon when energized such that the brake member is attracted to the core when one winding is energized and is released when both windings are energized. In the embodiment shown, windings 22 and 24 are wound on a central stationary core leg 26 having four integral outer legs 29, 31, 33 and 35 terminating in five co-planar pole faces 28, 30, 32, 34 and 36 projecting through a coppershading ring 36A. A brake disc 12 is slidably mounted on three bolts 21 to a hub-member 14 secured to a motor shaft to be braked, said brake disc being urged towards the hub flange 18 by coil springs 20. In operation, winding 22 is maintained energized and retains the brake disc against the pole faces to prevent relative rotation between the motor shaft and core. When winding 24 is energized, the magnetic fluxes are arranged to oppose and nullify each other leaving the brake disc and shaft free to rotate. In a control circuit, Fig. 2, the winding 22 is connected across a bridge rectifier 43 connected to terminals 42, 44 of an A.C. supply 46. Terminal 42 is connected to a single pole double throw switch 50 selectively supplying clockwise and anticlockwise motor coils 56 and 58 respectively. Winding 24 is connected across a bridge rectifier 45 coupled across the input of the motor coils, the arrangement producing opposed equalizing fluxes when either of contacts 52 or 54 are made by switch arm 48 and an unopposed brake-inducing flux of winding 22 when arm 48 is neutrally placed as shown. A break in the supply circuit as shown at 64 would release the motor shaft regardless of the switch selection. In an alternative embodiment, Fig. 3 (not shown), the windings 22 and 24 are formed by a centretapped coil fed directly with A.C. current, the winding 24 being connected in series with the motor coils.

Abstract: 1413022 Apparatus for calculating ship's metaceritric height LASTFORDELNINGSINSTRUMENT & CO KB AB 27 July 1973 [28 July 1972] 35974/73 .Heading B7M [Also in Division G4] An apparatus for calculating the metacentric height of a ship comprises a first circuit for the or each cargospace in the ship and for generating a first electrical signal representing the weight of cargo within that space, a second circuit for the or each cargo space and for generating a second electrical signal representing the height above the ship's keel of the centre of gravity of the cargo in that space, a third circuit or circuits for the space or respective ones of the spaces for generating a signal equal to the transverse second moment of area of that space multiplied by the density of liquid in that space, if the cargo in that space is liquid, a first summing circuit connected to the first circuit or circuits to generate a signal representing the ship's displacement, a multiplying circuit connected to the first and second circuits to generate a signal representing the vertical moment about the keel of a cargo in a space, a second summing circuit connected to the third circuit and to the multiplying circuit and a dividing circuit connected to the first and second summing circuits. In one embodiment the signal from the dividing circuit is fed to a subtracting circuit together with a signal from a function generator representing the height of the ship's metcentre above the keel (km) minus the light weight vertical moment divided by the ship's displacement and the signal from the subtracting circuit which consequently represents the metacentric height (GM) is fed to a suitable indicator. In a second alternative embodiment, a function generator generates a signal representing the height of the metcentre above the keel times the ship's displacement minus the light weight vertical moment about the keel of the ship and this signal is fed to a subtracting circuit arranged in the second summing circuit and the consequent signal (representing the total vertical moment of cargoes plus any signals from the third circuit or circuits minus the signal from the function generator) is fed to the dividing circuit which also receives a signal from the first summing circuit (representing the ship's displacement). The resulting signal which represents the metacentric height (GM) is then fed to a suitable indicator.

Title: Improvements in and relating to electro-magnetically operated overload switches
IPC: H01H71/24
Filed: 1934-12-14
Abstract: 449,248. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd.., Crown House, Aldwych, London. Dec. 14, 1934; Nos. 35984 and 35985. Convention dates, Dec. 15, 1933 and Feb. 6, 1934. [Class 38 (v)] A rapidly - acting electromagnetic overload switch which may be utilized for the protection of rectifiers is provided with main and auxiliary contacts operatively connected, a solenoid for opening said contacts having two windings, one of which in the closed position is connected in series with the main and auxiliary contacts and is effective to open the latter when the current exceeds a predetermined value, the other winding being connected across the auxiliary contacts and arranged upon opening of the latter to be connected in series with the first-mentioned winding and the main contacts whereby an increase is produced in the tractive force of the solenoid for opening the main contacts. As shown in Figs. 1 and 8, a core e is normally under the control of a series coil a of relatively small dimensions. On a predetermined excess of current, however, the core commences to move upwardly and a bridging bar d attached to the core breaks the circuit between auxiliary contacts b, b<1> so removing a short-circuit from a much larger coil a<1> which thereupon assists the coil a in rapidly completing the raising of the core. During this movement main contacts i, i<1> are separated by means of struts g and the arrangement is such that the separation of the main contacts occurs not more than a quarter of a cycle after the separation of the auxiliary contacts. Thus, if the latter had separated on approaching a maximum value of the A.C. supply, the main contacts will have separated before the current passes through the next zero value so that no fresh arc will form between the main contacts during the subsequent rise of current in the opposite direction. If necessary, this may be ensured as in Fig. 8, by attaching magnetic plates l, Fig. 8, to the contact springs f, f<1>, these plates being held by series electromagnets, which also act as blow-out magnets, until a zero value of current is reached. The core e is retained in the raised position by the struts g in the dotted position shown in Fig. 1 and is restored manually by a sliding bar h, Fig. 6, connected by struts r to the main contact springs f, f<1>. On sliding in to the dotted position the core is released and falls to the position shown and on returning the slide the main contacts i, i<1> are automatically reclosed. A quick closure is produced by lost-motion between the operating button s and the slide h. When employed on D.C. circuits a current wave may be superimposed to force the current through a zero value or, alternatively, a strong blow-out field. or special arcing contacts may be employed for interrupting the current.
