Title: Improvements in or relating to apparatus for forming crystals
IPC: C13B25/00
Filed: 1966-03-11
Abstract: 1,135,635. Crystallizing apparatus; vacuum pans. MASCHINENFABRIK BUCKAU. R. WOLF A.G. March 11,1966 [March 11,1965], No.10934/66. Heading C6B. [Also in DivisionB1] Apparatus, Fig. 1, for forming crystals of a solute, such as sugar, in a supersaturated aqueous solution thereof comprises a heating chamber 3 arranged around a tube 7, and a propeller 12 carrying inclined blades 14, which are accommodated in an annular channel 18 between the upwardly and convergingly tapering, frustoconical upper surface of the propeller's boss 13 and a similar portion 9 within the lower part of the tube 7. The inlet 19 and outlet 20 of the channel 18 have substantially equal cross-sectional areas. The rotating propeller 12 circulates the solution or massecuite in the directions indicated by the arrows. The apparatus may be in the form of a vacuum pan, in which an aqueous solution of sugar is boiled and concentrated, by evaporation of water, until it becomes a massecuite. The pan has a body 1 with a funnel-shaped base 2 leading to a valve 28, through which massecuite can be discharged, and has a heating chamber 3 in the form of a calandria around said tube 7. The calandria comprises upper and lower walls 4 and 5, and a plurality of tubes 6, through which solution or massecuite can circulate. Steam is passed through the calandria. A tubular insert 8 is located within the tube 7. This insert 8 is preferably sealed to the tube 7, as shown, to enclose heat-insulating air in a space 27. The lower part of the insert 8 constitutes said portion 9. Above this portion, the insert divergingly tapers towards the upper wall 4, and may project thereabove, with increased diverging taper, to provide a flared extension 11. The lower edge 10 of the portion 9 may be below the wall 5, as shown, or flush with said wall. The propeller 12 is secured to the lower end of a shaft 15 rotatably mounted in a bearing block 16, supported by arms 17 within the insert 8. The arms 17 are preferably vane-shaped and inclined, so as to impart, to the solution or massecuite, a rotational movement opposite to that of thepropeller. Preferably the number of blades 14 and the number of arms 17 have no common integral divisor. A cavity 21 may be formed in the underside of the boss 13, and a plurality of rectilinear or curved ribs 23 may be carried on the inner wall 22 of this cavity, in staggered relationship with the blades 14, Fig. 3. The boss 13 may be pierced by holes or slots 24. Sugar solution is fed into the pan through a tube having a flared inner end 26, which may extend into the cavity 21, as shown in Fig.1.

Abstract: <PICT:1006166/C6-C7/1> In a method of brewing beer comprising continuously producing a stream of wort from a continuous mashing stage, boiling and hopping the wort and subsequently continuously fermenting it, the stream of wort is divided into two or more streams at some point between mashing and fermenting, and the separate streams are passed to individual continuous fermentation stages to provide different types of beer.  Referring to the drawing, pale malt wort, prepared in mashing and filtering apparatus 3, 4, in the mashing line 1, is divided into two streams which are passed into separate wort boilers 5 and 6 and hopping stages 7 and 8, respectively.  The stream to wort boiler 6 has sugar added from a supply 9 before entering the boiler and further sugar is added to the stream after boiling and hopping from a supply 10.  The other stream, on leaving the hopping stage 7, is further subdivided and different sugars are added to these streams from supplies 11 and 12.  The three streams of hopped wort then pass to the individual continuous fermenters CF1, CF2 and CF3 to be fermented into three different light beers.  The dark malt wort in mashing line 2 is similarly treated, as shown.  Portions of the streams for fermenters CF3 and CF4 may be led off and combined into a stream of intermediate colour leading to a fermenter CF7.

Reaction (1), viz. <FORM:0999600/C3/4> can be effected at room or elevated temperature, and usually in solution in an organic solvent which is immiscible with water. The hydrohalide can be removed by trapping, e.g. as an amine hydrohalide, or be allowed to escape as a gas.  In other embodiments (i) additional silane prior to hydrolysis is omitted, (ii) alkoxy silanes are used instead of halosilanes, and (iii) hydroxy-terminated siloxanes are replaced by siloxanes having terminal hydrolysable radicals. Numerous examples of catalysts are given for the reactions involving alkoxy silanes.  In a typical Example (2) a toluene solution of an OH-terminated dimethylpolysiloxane was added to a toluene solution of phenyltrichlorosilane and pyridine, and the resulting mixture was then added to water with stirring; after washing free of acids &c. the product was bodied by refluxing with toluene sulphonic acid. The copolymers can be mixed with phthalocyanins, oxides of Sb, Ti, Al, Fe or Zr, SiO2 (natural, fume or xerogel), sand, silicates of Al, Mg, Zr, Mg-Al, or Ca-Al, graphite, C black, or powdered Al, Fe, Cu or Zn, and heat cured, e.g. with tributylamine, iron octoate or cobalt naphthenate.

Title: Improvements in radio pulse-echo distance-measuring systems
IPC: G01S7/282
Filed: 1945-05-10
Abstract: 612,111. Automatic control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 10, 1945, No. 11803. Convention date, Sept. 25, 1942. [Class 38 (iv)] [Also in Group XL (c)] Phase.-In a radiolocation distance-measuring system in which the phase of the echo-pulse train is compared with that of a referenceoscillation train and a phase-shifter controlling the phase of one of these trains is automatically adjusted to maintain the two trains in a given phase relationship, the extent of the phaseshift necessary being an indication of distance, the echo pulses generate a sine wave and the reference train is also in the form of a sine wave, the two sine waves being fed to a phase discriminator. In the system shown, the oscillator O from which the transmitted pulses 13 are derived, feeds a reference sine wave 27 through an adjustable phase-shifter PS to a phase discriminator PD. The echo pulses 17, converted to square-wave form 19, are passed through a filter or tuned circuit FT to produce a second sine wave 22 which is fed to the phase discriminator through a transformer 24. The phase discriminator PD comprises balanced rectifiers 31, 32, of which the anodes are connected together through the secondary of the transformer 24 and the cathodes through the resistors 33, 34 and an inductor 35 to eliminate hunting. The reference sine wave is applied between the mid-points of the secondary of transformer 24 and inductor 35. A voltage output which varies in polarity in accordance with the phase difference of the sine wave inputs and in value in accordance with the extent of the phase difference appears across the elements 33, 35, 34. This voltage varies the bias in inverse relation on a pair of valves 36, 37 forming a balanced amplifier, the anodes of these valves being connected through a transformer 38 to one winding 39 of a reversible motor 41. The other winding of the motor 41 is energized by one secondary of a power supply transformer 44 having two secondaries. The other secondary through a phase-shifting circuit 46 supplies the input circuit of the balanced amplifier 36, 37 with a current 90 degrees out of phase. If the sine waves 22, 27 have a 90 degrees phase difference, there is no output from the discriminator PD. For any other phase difference the motor 41 will run in one direction or the other to drive the phaseshifter PS until the desired phase relationship is established. An indicator 54 also driven by the motor is calibrated in terms of distance. Alternatively, the phase-shifter PS may be placed between oscillator O and wave-shaper SO or after filter FT in the receiving path.
