Title: Improvements in automatic consistency controls
IPC: G01N11/00
Filed: 1941-12-02
Abstract: 554,563. Consistency control systems. PAPER & INDUSTRIAL APPLIANCES, Inc. Dec. 2, 1941, No. 15526. Convention date, Nov. 28, 1940. [Class 135] In a system for regulating the consistency of the supply of fluid stock such as is used for paper making or of rag stock used in the manufacture of dry felts or of free sulphide stocks by regulating the dilution thereof the variations in consistency are detected by a pair of submerged bubble pipes spaced in the direction of flow of stock through a flow channel arranged for a substantially constant flow volume of said stock. In the form shown in the Figures a tank 11 having a rounded or bevelled end 20 is divided by a partition 12 terminating short of the end 20 to provide a U-shaped flow passage 13 separated from an inlet chamber 21 by an adjustable weir 14 and from an outlet chamber 22 by an adjustable weir 16. Stock entering through a pipe 23 flows through the chamber 21 and over the weir 14 to the flow passage 13 excess passing over an adjustable weir 15 direct to the outlet chamber 22. Stock is discharged from the flow passage through a valve controlled orifice 25 excess over requirements passing over the weir 16 to the discharge chamber. The weirs are formed by planks 27 inserted in grooves 28, 29. The bubble pipes 34, 35 are housed in a casing 39 inserted in the partitions 12 and are provided with opposed discharge nozzles 36 mounted in plates 70 adjustably mounted over slots in the casing 39. The upper ends of the bubble pipes are connected by coiled pipes 41, 49 to a U- shaped casing 42 adapted to be supplied with water through a pipe 51 controlled by a valve 52 to flush the bubble pipes. Compressed air from a pipe 48 passes through a reducing valve 47 to a manifold 45 fitted with a pressure gauge 46 and thence through pipes 41<SP>1</SP>, 49<SP>1</SP>, throttling chambers 44, 50, cocks 43, 50<SP>1</SP> and casing 42 to the bubble pipes. From the chambers 44, 50 pipes 53, 55 conduct the differential pressure in the bubble pipes to a regulating instrument such as that known under the trade name of Stabilog. This instrument has a recording chart 60 preferably with two recording styluses 61, 62 one making a record graph of the consistency of the stock leaving the tank, the other a record graph of the consistency of the undiluted stock. The instrument 54 controls the flow of air through a pipe 57 to a diaphragm chamber 33 to actuate a valve 32 controlling the supply of diluting water through a pipe 30 to a perforated enlarged terminal section 31 arranged immediately in front of the weir 14.

Title: Improvements relating to rolling mills and to automatic compensation of deflections
IPC: B21B27/05
Filed: 1939-05-25
Abstract: 529,735. Rollers. SEDZIMIR, T., (known as SENDZIMIR, T.). May 25, 1939, No. 15531. [Class 42 (ii)] [Also in Groups XXII and XIII] Deflection of the rolls of a rolling mill is compensated for by interposing between the roll shell 3 and the roll shaft 1 an intermediate shell 2 e.g. of softer cast iron and thicker at the ends or by cutting annular end grooves 2, Fig. 2, whereby the outer shell can deflect more at the ends to be equal to the deflection in the middle. In cluster mills the support rolls 5, Fig. 6, are hollowed out increasingly towards their ends 4 to provide end yielding. The support rollers may comprise a series of separated rings on a spindle the rings of the corresponding support roller being staggered in relation to the rings of the other support roller.
Patent GB-761281-A (GB)
Title: Process for the fractionation of microporous solid particles
IPC: B03B1/00
Filed: 1954-05-26
Abstract: In a process for the fractionation of a mixture of particles of microporous solids having the same skeletal densities but different pore size distributions into fractions consisting of particles having pore volumes made up predominantly of pores of smaller and larger diameters, a wetting liquid is incorporated in the mixture in an amount of between 20 per cent and 80 per cent of that required to fill all the pores in the particles, the resulting particles are placed in a partition liquid which is immiscible with said wetting liquid and of density sufficient to float a portion of said particles, and the floated particles are separately collected.  The wetting liquid, which may be water or a lower alcohol, e.g. methanol or ethanol, preferably has a lower density than the partition liquid in which case, since the smaller pores are preferentially filled with the wetting liquid, the floated portion consists of particles having the smallest average diameter, and may be incorporated by (a) mixing the required amount with the particles or (b) adding enough to fill all the pores and then evaporating some liquid from the mixture until it remains only in the smaller pores.  The mixture is preferably allowed to age after the addition of the wetting liquid in order to ensure its equilibrium distribution.  The partition liquid may be one or a mixture of liquids, e.g. hydrocarbons and their halogenated derivates, or may be a liquid weighted with very fine powders, e.g. barium sulphate and lead sulphide, and is preferably saturated with the wetting liquid before use.  The separation of the floated and sunken particles may be effected by skimming, or by passing through a centrifuge or a hydrocyclone. The process is said to be well suited for the separation of adsorbents such as activated carbon, silica gel and activated alumina, and catalysts such as silica-alumina, silica-magnesia, silica-alumina-zirconia, silica-alumina-boria, alumina-boria and aluminium fluoride-alumina.  By way of example is described the fractionation of a silica-alumina cracking catalyst using water as the wetting liquid and a mixture of carbon tetrachloride and ethylene dibromide as the partition liquid. Specification 648,717 and U.S.A. Specifications 2,430,015 and 2,631,968 are referred to.

Abstract: 804,704. Towing target aircraft. DEL MAR ENGINEERING LABORATORIES. May 18, 1956 [July 11, 1955], No. 15613/56. Class 4. A device for releasably holding an aerial target 32 to an aircraft having a reel and cable 13 fixed to the target, comprises a cradle 14 open at one end and mounted on the aircraft so that the said end faces rearwardly and guide means for passing the cable into the framework coaxially therewith, so that the target is drawn into the framework as the cable is wound onto the reel, and released as the cable is unwound. Fig. 1 shows an aircraft equipped with a device at each wing tip, and a reel apparatus 10 driven by a series of vanes 12. Each wing tip tank 15 has its aftermost portion removed, and replaced by a portion 17, Fig. 4 reinforced by a diaphragm 22. Rods 33 and 34 forming the cradle extend aft from the portion, the rods 34 being shaped to conform to the nose of the target, which may rest on a ring 37 with padding 38, and a second similar ring further aft (not shown). A telescopic tubular cable guide 23, 42, 45, 47 is secured to diaphragm 22, and is urged to the extended position shown by a spring 51 acting between a washer 52 and a plate 35 on diaphragm 22. The cable passes over a pulley 25 and through the cable guide. When the cable is unwound from the reel, the spring 51 acts to urge the target clear of the cradle. When the target is wound in, the spring and telescopic cable guide act as a shock absorber. In the embodiment of Fig. 6, the cable guide means comprises a fixed cylinder 61 and an inner telescoping cylinder 74, cooperating stops 75 and 77 being provided. The outer end of cylinder 74 is shaped to receive the nose of the target as shown. A further cylinder 78 serves as an abutment for a collar 79. A spring 83 extends between this collar and the outer end of cylinder 74, acting in the same way as the spring 51 of Fig. 4. In an alternative construction, a framework is mounted on the rear of each reel apparatus 10, Fig. 1. The Specification also describes a cable cutting device, Fig. 8 (not shown) in which the cable passes through a cylinder, and a piston at one end thereof can be driven by electrically detonated explosive charges to sever the cable. A resersible counting device is also provided, in which each revolution of pulley 25 adds to or subtracts from an indication given to the operator of the length of cable on the reel.

Title: An improved process for the manufacture of transparent and colourless condensation products of urea and solid polymers of formaldehyde
IPC: C08G12/12
Filed: 1926-06-22
Abstract: 271,264. Steppes, F. E. K., and Traun, H. O., (trading as Traun & S÷hne, vorm Harburger Gummi-Kamm-Cie., H.). June 22, 1926. Right to Patent relinquished. Urea-formaldehyde condensation products. - Colourless condensation products suitable for use as glass substitutes are obtained by dissolving urea in an aqueous solution of a formaldehyde polymer of a strength exceeding 40 per cent, boiling the solution for a short time in an open vessel, and hardening the product by further beating at a temperature below 100‹ C. The formaldehydepolymer solution is obtained by the use of suitable reagents, such as ammonia, alkalies, and amines, salts such as formates, acetates, and sulphites, or acids such as hydrochloric and aromatic sulphonic acids, which reagents, particularly if they are capable of affecting the condensation catalytically, are used only in the amount required to produce the solution. In an example, 504 parts of paraformaldehyde are dissolved in 100 parts of 7 per cent ammonia and 200-240 parts of water, and 480 parts of urea are dissolved in the solution. The solution, after heating to boiling in an open vessel for about ten minutes, gives a viscous product which, prior to hardening, may be mixed with soluble dyes or with insoluble pigments and filling materials.

Abstract: 156,944. Galloway, T. L. Oct. 29, 1919. Magnetic tests. -- A magnetometer consists of a bar magnet 9, Fig. 2, mounted on a flat mirror 8 suspended by a fibre of unspun silk or a fine wire 7. The other end of this is attached to a pendant 6 of the same weight as the mirror and magnet. The whole is mounted within a square or circular box 18 having windows 19, 20. The stems of the mirror 8 and pendant 6 are clamped, when the instrument is not in use, by clamps 21, 22 operable from outside the box 18. In use, the box is first set vertically with the pendant below the mirror. The pendant is then unclamped and allowed to turn freely, so as to remove any twist from the suspension. The pendant is then clamped, the box inverted, and the mirror unclamped. Motion of the mirror is restricted to a small arc by an arm 14, attached to the stem of the mirror, moving between a pair of stops 15. The attachment of the fibre to the mirror or pendant is shown in Fig. 5. The end of the fibre is passed through a slit in the end of a small cylinder 16 of wood, a few turns are wound round the cylinder to adjust the length, and the fibre is again passed through the slit. The cylinder is then passed through a triangular hole 17 in the end of the stem and turned across this, as shown. The clamp for the pendant is shown in Fig. 3. The stem 6 of the pendant is damped between plane parallel surfaces, of which one, 10. is fixed. and the other forms part of a stirrup 11 and is moved perpendicularly to its plane so as to avoid rotation.of the pendant when clamping. The clamp for the mirror is similar, but the stem is shaped to fit a notch in the fixed bar to position the mirror. A pair of collars 13 on the stem prevent endlong motion. A method is described by which the instrument may be used for setting the optical axis of a theodolite in the magnetic meridian.
