Abstract: 683,354. Radio navigation. SPERRY CORPORATION. Jan. 19, 1951 [Jan. 21, 1950], No. 1501/51. Class 40 (vii). [Also in Group XXXV] In an automatic speed control system for an aircraft such as that described in Specification 655,172, [Group XXXV], wherein the throttle control is controlled in accordance with airspeed, a further speed control term is added from the elevator channel (e.g. from a glide path receiver) to counteract oscillations in air-speed due to changes in the inclination of the craft. As shown, and as described in Specification 655,172, [Group XXXV], air-speed-error signals from an E-type pick-off 19 associated with an air-speed-indicator 1, are fed through a phase-sense detector 49 and a network 69, 71, 73, giving the error plus its rate of charge to a balanced amplifier 75 controlling the throttle operating servomotor 85. The rate of throttle movement obtained from a tachometer generator 91 is fed through a network 93, 95, 97 (giving the rate of movement plus its integral) to the other input of the balanced amplifier 75. In accordance with the invention, the D.C. error signal from a glide path receiver 59 is modulated at 65 and added in series with the speed error signal or alternatively, Fig. 2 (not shown), a signal from the elevator channel of the automatic pilot, comprising glide path and pitch attitude error signals may be added to the speed error signal.

Title: An improved machine for filling and capping bottles
IPC: B67C7/00
Filed: 1925-01-20
Abstract: 241,770. Carpmael, W. P., (Crown Cork & Seal Co. of Baltimore City). Jan. 20, 1925. Bottling; capsules, applying. - A bottle filling and capping machine comprises a head having a capping die and liquid delivery means, and a bottle support, one of these elements being moved towards the other with a given stroke and the other being moved towards the first element with a variable stroke dependent on the height of the supported bottle, when the head and bottle are being placed in filling relation, a further relative movement taking place for the capping operation. A standard 12 on a base 11 carries a slidable plunger 16 provided with a filling and capping head 17, the plunger 16 being connected by a web 69 through the medium of a spring 61 in a casing 60 to a rod 42. The lower end of the rod 42 is secured to a yoke 46 adapted to be moved vertically by cams 47, 49 on a shaft 50 which moves half a revolution every time a clutch 55 on a driving shaft 53 is operated. The base 11 contains oil which can pass through a non-return valve 91 and pipe 88 to a chamber 45. From this chamber 45 it is forced by a plunger 44 on the yoke 46 through a pipe 86 to a chamber 85 to raise a plunger 84 abutting against the supporting tube 77 of an adjustable bottle-rest 75. In operation, a half revolution of the shaft 50 and cams 47, 49 lowers the rod 42 and yoke 46, drawing down the head 17 and raising the bottle rest 75. When the bottle neck enters the filling head a gasket 33 is compressed to seal it therein and the head and bottle move downwards, the oil displaced by the plungers 44, 84 being displaced through the pipe 88, a relief valve 89, and a pipe 104 which delivers it to the top of the standard 12 so that it may lubricate the working parts of the machine as it returns to the base 11. The plunger 44 in its downward stroke seals the pipe 86 and locks the bottle rest in the filling position, this locking occurring before the end of the stroke of the plunger 44 so that the subsequent movement draws the head 17 down on to the bottle to wedge the gasket 33 against it, whereupon liquid is supplied to the bottle through a pipe 31 and an apertured ring 26 in the head 17. A further half revolution of the shaft 50 applies to the bottle a " crown cork " or other cap previously placed in the head 17. The rod 42 is drawn further downwards, the bottle neck rises in the head 17, lifting the cap into contact with a presser foot 19 slidable in the head against the action of a spring 22, and a conical throat ring 18 applies the cap to the bottle, the coils of the spring 22 being completely closed to make the head act as a solid member. If the bottle neck is unusually long, the spring 61 yields allowing the head 17 to be displaced relatively to the rod 42. The remainder of the half revolution of the shaft 50 raises the head 17 and allows the bottle rest to fall by gravity, any oil required in the chamber 45 being supplied through the valve 91.

Patent GB-798970-A (GB)
Title: Improvements in or relating to methods of and apparatus for the steam distillation treatment of liquids
IPC: B01D3/38
Filed: 1956-01-19
Abstract: <PICT:0798970/III/1> Volatile substances are removed from liquids, as in the deodorization of cream, by passing the liquid successively through a series of steamdistillation stages, introducing live steam from an extraneous source into the liquid in a plurality of the stages, injecting at least some of the used steam (together with the admixed vapours) from one or more of the later stages into the liquid in one or more of the earlier stages, and discharging from the system, e.g. to a condenser, steam and vapours withdrawn directly from a plurality of stages.  The apparatus shown comprises four distilling vessels 1, 2, 3, 4, a cooler 39 for the treated liquid, and a two-stage ejector condenser 24.  The vapour-space of vessel 3 is connected to liquid-inlet pipe 5 of vessel 1 via venturi 28; and the vapour-space of vessel 4 is connected to the liquid-inlet pipe 6 of vessel 2 via venturi 32. In an example, cream is preheated to 170 DEG  F. by heat-exchange with exhaust water from the condenser, and the preheated cream is then introduced into the apparatus through inlet 44.  Live steam is injected through inlet 30 into venturi 28 where it compresses used steam from vessel 3; and the compressed mixture carries the cream up pipe 5 into vessel 1 where steam distillation takes place at 210 DEG  F.  The vapours pass through outlet 21 and valve 22 to the second stage of condenser 24, and then to waste.  Pasteurized cream flows from vessel 1 through float valve 17 to pipe 6 where it flashes; and it is carried up pipe 6 into vessel 2 by a blend of live steam, introduced through inlet 33, and used steam from vessel 4.  Steam distillation takes place at 205 DEG F. in vessel 2, and the vapours pass through conduit 23 to the second stage of condenser 24.  The temperature and vacuum in vessel 2 are determined by the setting of snifter-valve 25 on the condenser; for when the vacuum exceeds a certain value, the valve opens to admit air.  The temperature and pressure within vessel 1 are controlled by valve 22.  The cream leaves vessel 2 through float valve 18; it flashes in pipe 7 and is carried up into vessel 3 by live steam supplied through inlet 29.  The cream is steam distilled at 197 DEG in vessel 3; it then flows through float valve 19 into pipe 8 where it flashes and is carried up into vessel 4, where the temperature is about 168 DEG  F.  The cream is next carried up into cooler 39, the flash-steam from which being conveyed to the first stage of condenser 24.  The cream is finally pumped to a cooler (not shown) at atmospheric pressure, by pump 43. Specification 664,212 [Group VI], is referred to.

Abstract: 1,020,213. Centrifugal liquid-liquid contacting apparatus; treating gases with liquids; evaporation of liquids; rotary homogenizer. W. GLASER. Dec. 10, 1962 [Jan. 18, 1962; April 4, 1962; June 7, 1962], Nos. 1978/62, 12932/62 and 22123/62. Headings BIB, B1F, B1L, B1R and B1V. [Also in Division F4] Centrifugal apparatus for bringing two or more phases into intimate contact or for the evaporation of liquids, comprises a stator b surrounding a rotor a consisting of layers i of expanded metal sheet mounted at right angles to an axial shaft f, the layers being assembled so that the zig-zag profilations of the metal strands of adjacent layers touch and/or overlap but there is sufficient free space left within the rotor for the phases to be centrifuged through it when the rotor is driven, e.g. by a motor connected to pulley c by belts. The rotor may be driven at such angular velocities that sonic and ultrasonic waves are produced by the rapidly moving strands of expanded metal. The apparatus may be used for the evaporation of liquid under vacuum; films of liquid are formed on the metallic strands, or the liquid is also subjected to atomization. The apparatus may be used for washing furnace gases with liquids, contacting air with water or an aqueous salt solution, or drying gases such as HCl, HF, SO 2  and H 2 S with dehydrating-liquids such as H 2 SO 4 . The gas is introduced through inlet o, and the liquid is fed through pipes n into the hollow axial region d of the rotor. Part of the liquid spray discharged from the rotor runs down the wall of the stator into vessel k, and part is collected in channel j. If desired, some of the liquid may be returned to the rotor. Sea water may be used in the treatment of furnace gases, in which case soft water is obtainable from the effluent gases. The apparatus may be used for liquid-liquid extractions, e.g. the extraction of uranyl nitrate from leaching brine with a solvent comprising tributyl phosphate and hydrocarbons, and the extraction of formic and acetic acids from cellulose black liquors with methyl ethyl ketone. The apparatus may also be used for emulsifying two immiscible liquids, and for emulsifying gases in liquids e.g. aeration of liquids. Several units of apparatus may be superposed to form a distillation column. When the apparatus is used for spray drying, e.g. of soft fruit, the axis of the rotor is preferably horizontal. The apparatus can also be used as a burner (see Division F4).

Abstract: Linear polyamides of high melting-points and good thermal stability are obtained by heating at 150-400 DEG  C. compounds of formula <FORM:0782441/IV (a)/1> where R, R1 are H or aliphatic, aromatic, cycloaliphatic or heterocyclic groups.  The compounds exist as stereoisomeric isomers and according to the isomer chosen polyamides preponderating in this isomer are obtained.  Examples of monomers used are 4-aminocyclohexyl acetate, ethyl 4-amino-cyclohexyl acetate, 4-acetylaminocyclohexylacetic acid, ethyl 4-acetyl aminocyclohexylacetic acid, the separate cis or trans modifications or their mixtures being used.  The polymers may be mixed with other polyamides to modify their melting-points, water resistance &c. or co-condensed with other monomeric compounds from which polyamides are derived.ALSO:Cis and trans-isomers of amino carboxylic acids of the general formula <FORM:0782441/IV (a)/1> where R, R1 are H or aliphatic, aromatic, cycloaliphatic, heterocyclic, ammonium or quaternary ammonium substituents are obtained in the following ways: (1) benzyl cyanide is nitrated at low temperature (Berichte 62, 187 (1829) and the resultant isomer mixture is recrystallized from alcohol to give p-nitrobenzylcyanide which is saponified and esterified with alcoholic HCl to give ethyl p-nitrophenylacetate. The latter is converted to ethyl 4-aminocyclohexylacetat by hydrogenation and reduction in presence of reduced Pt. catalyst (Berichte 45, 3589 (1912) and 52, 1519 (1919)); (2) phenylacetic acid is nitrated, the isomers separated and converted as described above; (3) p-nitrotoluene is halogenated to yield p-nitrobenzylhalides.  The latter are reacted with an inorganic salt of HCN to give the cyanide which is hydrolysed to p-nitrophenylacetic acid or hydrolysed and esterified to ethyl p-nitrophenylacetate; (4) aqueous solutions of the alkali metal salts of p-nitrophenyl acetic acid are hydrogenated to corresponding salts of 4-aminocyclohexylacetic acid by treatment with hydrogen as at 150-250 DEG  C. under pressures of 50-200 atmos. in presence of Raney nickel or other catalysts.  The aminoacids are polymerized to form fibre-forming polyamides.
