Title: Improvements in apparatus for aerating liquids
IPC: B67D1/02
Filed: 1921-01-19
Abstract: 174,284. Billows, A. J. Jan. 19, 1921. Dispensing liquids. - In apparatus for aerating liquids in which the liquid and gas are introduced separately and in proportionate quantities into the aerating chamber, as in the apparatus described in Specifications 26303/06, [Class 14, Beverages], and 15378/10, [Class 14 (i), Aerating liquids &c.], the aerated liquid is passed into a storage chamber 20 cooled by the expansion of the gas used for aerating whence it passes to a secondary storage chamber 55 the contents of which can be drawn off at high or low pressure as desired. The liquid is supplied to the aerating chamber I by a pump driven by a variablethrow crank disc 6 on a shaft 4. The gas passes from a cylinder 13 through a pressure reducing valve 15, and a coil 19 arranged in the storage chamber 20 to a casing 26 containing a valve opened by cams 28 on the shaft 4, so arranged that the liquid and gas enter the chamber 1 simultaneously. The aerated liquid passes to the chamber 20 through pipes 29, 30 controlled by the valve shown in Fig. 4. This valve consists of a hexagonal or like piston 44 pressed against a partition 132 in a cylindrical casing 31 by a spring 46. The rod 45 of the piston 44 is of square or like cross-section where it passes through a circular opening in the end of the casing 31 communicating with the pipe 29. The valve 44 is pressed back from the partition 132 by cams 42 on the shaft 4 acting on a cap 41 on a rod 43 clamped to a diaphragm 4 and passing through a fitting c screwed into the side of the chamber 1. The liquid can thus flow past the rod 45 and the piston 44 and the end of the rod 43, which is square where it passes through a circular opening in the partition 132, to the pipes 30 and the chamber 20. From the chamber 20, a pipe 51 leads to a casing 53 containing a valve similar to the valve 44 from which a pipe 54 leads to the upper part of a secondary storage chamber 55. From the chamber 55, pipes 57, 60 lead through similar valves to a draught outlet 58 and the atmosphere respectively. These three valves are actuated bv cams mounted independently on a spindle 77 and operated by hand, so that the chamber 55 can be filled from the chamber 20 and the contents drawn off, either as they are, or after the pressure has been relieved through the pipe 60.

Title: Processes for producing multi-coloured dyeings on nylon
IPC: D06P3/24
Filed: 1962-01-24
Abstract: Multifilament nylon is dyed to produced multicoloured dyeings in a single dyebath which contains a dyestuff with at least 2 sulphonic acid groups and 0-3 reactive groups per molecule, the sum of the sulphonic acid and reactive groups being at least 3, at an acid pH in the presence of a condensation product of an aryl sulphonic acid and a compound containing an aldehydic or ketonic carbonyl group in an amount 0.1-5.0% on the weight of nylon, insufficient to reserve the said dyestuff.  The preferred nylon is nylon 6 which may be combined with nylon 66 in which case the nylon 66 is reserved to give undyed areas and it may contain little or no pigment or filler, e.g. bright nylon, or it may be semi-dull nylon.  Especially preferred are multifilament yarns of total denier at least 1000 and a denier per filament of 2-10 in particular yarn having a tenacity of less than 7 grams/denier e.g. tufted carpets, woven or knitted piece goods. Suitable dyestuffs are found in the acid, milling, direct and reactive dyestuff series.  The preferred dyes are those containing at least 3 sulphonic acid groups per molecule.  The condensation products may be derived from mono-di- or trisulphonic acid substituted benzene or naphthalene which may be further substituted with lower alkyl, hydroxy, nitro or amino groups together with formaldehyde, acetaldehyde, benzaldehyde, benzoin or acetone and their sodium salts.  Those condensates employed in the examples are naphthalene sulphonic acid/formaldehyde and alkyl-naphthalene sulphonic acid/benzoin condensates (a number of others are specified).  The condensation product may be applied before or preferably with the dyestuff from a bath made acid with an organic or inorganic acid or an acidic salt thereof; acetic acid only is used in the examples.  The pH may be lowered during the course of the dyeing. The dyebath may also contain a dyestuff with less than 2 sulphonic acid groups per molecule as well as small amounts of other usual additives such as Glaubers salt or a non-ionic surfactant.  A pretreatment with formaldehyde or paraformaldehyde in a 2% boiling aqueous bath calculated on the weight of fibre may be employed. Examples are given.  Specification 680,862 is referred to.

Patent GB-973122-A (GB)
Title: Single degree of freedom gyroscope
Inventor: QUERMANN THOMAS RICHARD
IPC: G01C19/42
Filed: 1961-01-25
Abstract: 973,122. Gyroscopic apparatus, UNITED AIRCRAFT CORPORATION. Jan. 25, 1961, No. 2878/61. Headings G1C and G1N. In a single degree of freedom gyroscope the field structure of the electric spin motor is mounted on the fixed casing 99 instead of on the gimbal 98 so that the armature, which is on the rotor, may rotate relative to the field structure about two orthogonal axes viz. the spin axis and the output axis. The housing 99 is of permanent magnetic material having a laminated pole shoe 49 symmetrical about the north pole line N and two laminated pole shoes 50, 51 symmetrical about the south pole line S to form the field structure. Pole faces 94-97 on the inner surface of the floated gimbal 98 are symmetrical with respect to pole shoes 49-51 in the null position. The rotor has spaced armatures 62, 63, each provided with twelve teeth and twelve semi-closed slots and held by snap rings 76-79 on a spider 81 formed with a hub and six pairs of legs. The armatures 62, 63 are wound with input and output windings connected respectively to commutator bars such as 40-46 co-operating with brushes 54, 55 and commutator bars 13-24 co-operating with brushes 52, 53. As applied to a rate gyro, D.C. is applied from source 100 through terminals 74, 75 leads 70, 71, terminals 66, 67, to brushes 54, 55 so that the rotor picks up speed, a centrifugal switch thereon maintaining the speed constant. When a turn occurs about the input axis, gimbal 98 precesses about the output axis against the torsion of a bar 89, a corresponding D.C. output signal being passed from brushes 52, 53 through terminals 64, 65 and leads 68, 69, to terminals 72, 73. Damping is effected by a coil 106, the viscosity of the fluid which floats gimbal 98, and by eddy currents produced by having the gimbal 98 of non-magnetic material having a low resistivity. Since the viscosity of the fluid decreases with increase of temperature, damping decreases also and to compensate for this the non-magnetic material of gimbal 98 may have a slightly negative temperature coefficient of resistance and the ends of coil 106 may be shorted through a resistor 111 having a negative temperature coefficient. As applied to a displacement gyro the torsion bar 89 is removed, or rendered inoperative, and the ends of coil 106 are connected respectively to terminal 107, and either directly or through resistor 111 to terminal 108 so that the coil 106 is used as a torque. In modifications the input commutator is replaced by slip rings and the input comprises three-phase A.C. the output then being D.C. from the output commutator, or single or three-phase A.C. from slip rings or combinations thereof as required. Armatures 62, 63 may be formed as a single armature.

Filed: 1933-01-30
Abstract: 409,854. Mixing fluids in flow. PATERSON, W., Windsor House, Kingsway, London. Jan. 30, 1933, No. 2922. [Class 86.] Means for proportionally adding a solid, liquid, or gaseous reagent to a liquid stream consists in bleeding through a pressure liquid motor a volume of liquid proportional to the main flow and utilising the motor to effect the addition. In the form shown, the pressures at the throat and up-stream sides of a Venturi actuate two pistons b, c fitted with racks d operating a drum on which is a cord connected with a valve e controlling the flow from a tank g to which liquid is fed through a motor m. The level of liquid in the tank is maintained by a ball-cock valve k, and the motor drives a pump n which supplies the reagent. The tank may be fed from the main stream or from a separate source of pressure liquid. In another form, the Venturi pressures act on the sides of a diaphragm, the movement of which operates the valve e, or the diaphragm may operate a lever, one end of which is connected to a valve controlling the admission of liquid to the tank, while the other end is connected to a float shaped so as to maintain balance when the discharge from the tank is proportional to the flow in the main stream.

Title: Autographic register
IPC: B41L5/14
Filed: 1922-02-01
Abstract: 191,629. Wyrick, C. E. Feb. 1, 1922. Registering webs.-In an autographic register, two or more paper strips pass from supply rolls between printing and impression rollers which are rotated by the pull on the strips, the printing- rollers being geared together for simultaneous operation and each being adapted to release the grip on the strip periodically so that exact registration of the printed matter on the associated strips is preserved notwithstanding slight differences in diameter of the printing-rollers. Three supply rolls 6 are shown supported on inclined faces 8 of brackets 5 so as to rest continually against impression rollers 11 which are held by adjustable springs 17 against the printing- rollers 14, which are interconnected by gears 23, 24. The strips pass between the rollers 11, 14, round guide-rollers 34, 36, over a writing-plate 40, and between feed-rollers 50, 53. Strips of carbon paper pass transversely across the plate 40 from a supply roll supported in a chamber within the main casing 1. The printing-rollers 14 have a flat or other non-printing part 29 between the ends of the printing-surface, which parts 29 release the strips 12 at intervals so that any slack, such as 55, in any strip due to one of the printing- rollers being of larger diameter than the others, will be taken up by the pull on the other strips during the passage of the flat part 29 past the roller 11. By this arrangement, the amount of strip fed from each roll during each revolution of the printing-rollers will be equalized and the printed matter on the superposed strips will remain in register.

Title: Improvements in or relating to detachable bits for rock drills
IPC: E21B17/04
Filed: 1943-02-26
Abstract: 564,106. Percussive drills. CRAIG, E. Feb. 26, 1943, No. 3147. Convention date, Oct. 7, 1942. [Class 124] [Also in Groups II and XXII] Drill bits for rock of the type formed with a socket to receive the shank of the drill rod, the socket and shank being shaped to secure proper locking by relative rotation, for example, by being formed in cross-section to an archimedean spiral, have the socket wall such that it will yield sufficiently to correct any deformation caused during manufacture. The socket wall 4, Figs. 2' and 5, is sufficiently thin so that in the event of deformation the socket and shank 2, Figs. 1 and 5, may be forcibly assembled and brought to proper mating fit by relative rotation caused by the operation of the bit in use. Only the cutting end of the bit is hardened and this is effected by taking the bits hot from the forging-dies, trimming, sharpening, reheating and placing with the cutting end downwards on a perforated travelling belt 5, Fig. 7, in a tank 7 fitted with liquid to such a depth that only the cutting jaw is hardened, the bits being discharged to a receptacle in which the socket ends cool slowly.
