Title: Evaporator
IPC: C02F1/04
Filed: 1950-03-30
Abstract: <PICT:0674385/III/1> <PICT:0674385/III/2> In an evaporator for seawater, comprising a boiler and a vapour-dome disposed below and above a separating-chamber respectively, wherein water is supplied to the separating - chamber through a constant-level device and then flows to the boiler the vapours are conducted from the boiler to the separating-chamber through a throttle conduit leading from the top of the boiler through the separating-chamber below the water-level therein, then passing externally of the shell of the evaporator, and re-entering the shell tangentially at the upper portion of the separating-chamber.  The formation of hard scale due to the deposition of magnesium carbonate in the apparatus is largely prevented by the pre-heating of the water, with consequent evolution of carbon dioxide therefrom, in the separating-chamber. In the evaporator shown, partition 18 separates boiler 19 from separating-chamber 20.  The boiler is heated by steam supplied through pipe 21 into a basket formed of deeply corrugated sheet 25 bent into cylindrical from, steam-condensate flows out of the basket through drain 29.  Water is supplied to separating-chamber 20 through inlet 55, is maintained at level WLI in the chamber by float valve 57, and flows to the boiler through a pair of pipes 59.  The steam raised in the boiler leaves it through aperture 33, and then flows through elbow 34 and pipe 35 the first part of which (see Fig. 5) is immersed below the water in chamber 20.  The pipe 35 turns upwards when outside the evaporator-shell, and is connected to a casing containing a butterfly-valve; while the casing is in turn connected to the upper part of chamber 20 by a pipe which enters the chamber tangentially.  Vanes 39 welded to partition 18 act as extended heating surfaces in transferring heat across the partition from the boiler.  The steam is largely freed from entrained water in chamber 20; and then passes through opening 46, pipe 41 and hood 48 into vapour-dome 17.  Water which forms within pipe 41 drains out on cone 43 through opening 42. The last traces of water are separated from the steam in dome 17, and the steam is lead through conduit 49 to a condenser.  The water separated in dome 17 drips through perforated plate 40, is collected by cone 50, and returned to chamber 20 by pipe 51. Specification 600,784 is referred to.

Abstract: 919,540. Automatic position and temperature control. ROLLS-ROYCE Ltd. March 7, 1961 [March 8, 1960], No. 8222/60. Class 38 (4). In an.automatic electric control system for a gas turbine, a fuel control member is connected to a memory device during setting to a desired position and is then maintained in the desired position by a power actuator controlled in dependence on the difference between the actual position of the fuel control member and the desired position as derived from the memory device. As shown, a fuel supply controller 11 for a jet engine 10 has a main control-lever 12 positioned through a follow-up system in dependence on movement of a. pilot's throttle lever 15. A temperature trim control lever 13 is positioned through an extensive linkage. 22 by a pilot's trim lever 23. During initial setting-up for automatic operation a catch 23a is engaged with. recess..31a and the trim lever moved by a motor 26, through a gear-box 27, under the control of a reversing switch 33 to a desired position shown on an indicator 25 connected to a synchro-transmitter 24. Simultaneously a synchro-transmitter 37, acting as a memory device, is connected to the linkage by the energization of an electromagnetic. clutch 36. When the switch 33 is in the " off" position the clutch 36 is de-energized and the synchrotransmitter 37 held stationary by a friction brake 38. The . output-of the synchro-transmitter 24, representative of the actual position of the trim lever 13 is compared with the output of the memory synchro-transmitter 37 in a comparison amplifier 39 which controls the energization of the motor 26 so as to maintain the trim lever in the desired position. When a switch 34 is changed from " manual " to " auto " operation the motor 26 is controlled through the amplifier 39 by the output of a bridge 42, responsive to the signal from a thermocouple 43, so as to maintain the turbine gas temperature constant. In a modification, a mechanical clutch 36 slips when an electromagnetic brake 38 is energized. The temperature control system is only operative when a speed-responsive switch 44, energized from tachogenerator 45 is actuated. Specification 901,888 is referred to.

Title: Process for producing fertilizers and products thereof
IPC: C05B1/04
Filed: 1956-03-16
Abstract: Phosphate fertilizers are produced by treating calcium, sodium, or potassium metaphosphate with a strong base consisting of sodium or potassium hydroxide, carbonate, oxide or peroxide, in the presence of water.  Pearl ash or soda ash are preferred.  The metaphosphate is hydrolysed to form the primary o-phosphate which is then converted by the base to the secondary o-phosphate.  The proportion of the alkali used should not exceed the stoichiometric quantity required, and the proportion of water should not exceed 3 to 4 times this quantity, the maximum quantity being required with maximum quantities of the alkali base.  In examples, calcium or potassium metaphosphate is mixed with potassium hydroxide or pearl ash dissolved in a little water, whereupon the temperature rises and a dry crumbly solid is produced. This is then stored and cured.  With a higher water conent a slurry is produced which is rendered crumbly by air drying at 250 DEG  F.

Title: Organic dihaloborines
Inventor: STERN DAVID RUSSELL
IPC: C07F5/02
Filed: 1959-03-11
Abstract: Organo dihaloborines are produced by reacting dichloro-or dibromo-borine (HBCl2 or HBBr2) with a hydrocarbon which contains at least one double bond or triple bond in an aliphatic chain or cycloaliphatic ring, and may have a chloro-or bromo-substituent, the reaction being carried out in the absence of water or oxygen.  The dichloroborine or dibromoborine is prepared by passing a mixture of hydrogen and boron trichloride or tribromide over granulated aluminium or magnesium at a temperature in the range 400 DEG -550 DEG C.  The dichloro-or dibromo-borine so obtained is then reacted, without separating it from unreacted boron trihalide and hydrogen, with the unsaturated hydrocarbon, this reaction being carried out at room temperature. The desired product is then separated from the unreacted boron trihalide by fractional distillation in an inert atmosphere. Examples 1 and 2 relate to the preparation of ethyl-dichloroborine CH3CH2 BCI2 and isopropyldichloroborine C3H7BCI2\t by reacting dichloroborine with ethylene and propylene, respectively.  Example 3 relates to the preparation of bis (dichloroborino) ethane C2H4 (BCI2)2 by reacting dichloroborine with acetylene. Example 4 relates to the preparation of bis (dichloroborino) butane CH3CH(BCI2) CH2 CH2 BCI2 by reacting dichloroborine with 1, 3-butadiene.  The bis compound may be esterified with methanol, and the ester hydrolysed with water, to yield butane diboronic acid.  In examples 5 and 7, cyclohexyldichloroborine and 1-methyl- 2-chloroethyldichloroborine are prepared from cyclohexene and 3-chloropropene, respectively. Example 22 relates to the preparation of C6H5 C(CH3) (B Br2) CH3 by reacting dibromoborine with a -methyl-styrene.  Example 37 relates to the preparation of bis (dibromoborino)-ethane by reacting dibromoborine with acetylene.

Title: Improvements in and relating to reversing gearing
IPC: B66D1/14
Filed: 1925-03-30
Abstract: 254,025. Ellson, B. E. March 30,1925. Planing.-Epicyclic reversing-gearing for actuating reciprocating parts in planing-machines &c. is controlled automatically from the machine through three or more brakes, in order to produce definite pauses at the end of one or of each stroke. Thus a winding-drum B, Fig. 14, is driven from a motor M in one way or the other according to which of two brakes indicated at X, Z is applied to elements S<2> and R of an epicyclic train. A third brake Y is for arresting the drum during reversal, and providing the pause. The brakes are applied in proper sequence by means such as cams U, V, W, Fig. 15, upon a shaft G, which is rocked. A screwed rod Q, Fig. 16, driven from the drum through constant gearing N carries travelling nuts O<1>, O<2>. A throw-over weight O<6> is carried by a lever O<5> which can turn loosely upon the shaft G, and actuates the shaft G with lost motion in either direction through a lug J extending between two levers H secured at an angle upon the shaft. Integral with the lever O<5> are levers O<3>, O<4> which are struck alternately by the nuts O<1>. O<2> to effect reversal by releasing one of the brakes X, Z and applying the other. As lever O<5> passes from position IV to position V, or from position III to position II, the brake F alone is applied to the drum directly. The required pause is effected by stopping the lever O<5> in its descent at positions V and II, and this may be done by a device like a clock escapement comprising a three-armed lever O<9> controlled by vanes A'. A quick-throw over linkage adapted to apply the brakes in the order XYZYX is shown in Fig. 10. Forms of epicyclic reversing-gear other than that shown in Fig. 14 are described, all operated by the two brakes X, Z. Some of these have double or stepped planetary gears, some have treble planetary gears, and in some there are separate gear trains.

Title: Method and apparatus for producing bunched beams of neutrons, ions and gamma rays
IPC: H05H3/06
Filed: 1964-02-28
Abstract: 1,045,522. Producing neutrons; particle beams. HIGH VOLTAGE ENGINEERING CORPORATION. Feb. 28, 1964 [Feb. 28, 1963], No. 8512/64. Heading G6P. In a device for forming pulsed collimated beams of neutrons, gamma-rays or charged particles, a pulsed ion beam is directed on to an inclined target surface. The beam has a periodic lateral sweep so chosen that the velocity of the point of intersection of the beam and the target surface is equal to the velocity of the emitted neutrons, gamma-rays or charged particles. When gamin-rays are formed, the intersection moves at the velocity of light. Owing to the movement of the point of impact of the ion beam in the target, damage to the latter is reduced. The incident ion beam may be either monoenergetic or velocity modulated. In the former case the incident ion beam is passed through a magnetic field to render the ion velocity vectors parallel so that the neutrons emerging from the target follow a single trajectory. In the latter case a more intense neutron pulse is formed at the target. However, the incident ions of different energies produce neutrons having different emergent directions. To neutralize this the ion beam is passed through a magnetic field which effects a lateral spread of the ion beam velocity vectors. Suitable targets are, for neutron production, beryllium, lithium and deuterium, for gamma production, aluminium, lithium, nitrogen, fluorine and chromium, and for charged particle production, lithium, nitrogen, beryllium, cadmium and bismuth.
