Title: Improvements in or relating to variable speed gears
IPC: F16H29/16
Filed: 1926-02-06
Abstract: 248,345. Aeppli, A. Feb. 27, 1925, [Convention date]. Variable-speed epicyclic gearing is controlled by a ratchet linkage which connects two elements of the train and rotates bodily round an adjustable eccentric axis. Thus a driving- shaft 1, Fig. 1, supports a frame 2 which carries stepped planets 3, 4 meshing with a sun gear 6 on a driven shaft 5 and a sun gear 8 which is controlled or driven through multiple-phase ratchets 18, Fig. 2, upon a sleeve 7. A drum 9 surrounding the ratchets is supported revolubly in a transverselydisplaceable carriage 11 and is connected by a drag-link 10, Fig. 3, to the planet-carrier 2. Ratchet arms 12 are connected by links 14 to the interior of the drum 9. When the drum 9 is concentric with the shaft 5, the ratchet gear and the epicyclic gear both turn solid, the resulting one-to-one drive being the lowest speed transmitted. As the carriage 11 is displaced, the arms 12 move round alternately faster and slower, and as each arm acts when moving fastest, the sleeve 7 and gear 8 are driven at increased speed. The speed of the shaft 5 thus increases from normal. The linkage connection 10 causes the speed of the drum 9 and therefore the speed of the shaft 5 to vary cyclically. In high-speed arrangements, the drum 9 may be driven uniformly from the carrier 2 by a pair of toothed gears 24, 25, Fig. 6, upon a fixed countershaft 16. Speed is varied by swinging the drum 9 round the shaft 16 as centre. The gears 24, 25 may be stepped so that the lowest speed is less than one-to-one. Resilient elements and fly-wheels may be used to render the drive still more smooth. The pawls 17, Fig. 2, are adapted to rock on pivots 19 within the arms 12, and the ratchet teeth and pawls are so arranged that when one edge of a pawl is over a ratchet tooth, the other edge of the pawl projects into the tooth gap. Provision is made for reversing the direction of drive of the ratchets to meet the case of interchange of functions of driving and driven shafts, as when a vehicle is coasting. The arms 12 are for this purpose moved laterally between two oppositely-set ratchets 18, 18<1>, Fig. 8. In modified arrangements, three-element spur epicyclic trains are used; bevel trains may also be used.

Title: Process for dyeing or printing hydrophobic fibrous materials
IPC: C09B62/08
Filed: 1962-01-31
Abstract: Hydrophobic fibrous materials, e.g. of cellulose-2 1/2 -acetate and triacetate, aromatic polyesters, polyamides, polyurethanes, polyacrylonitrile or polyvinyl chloride, are dyed or printed using as dyestuff (a) a 1-monoarylmercapto anthraquinone which contains in the 4- position a hydrogen or halogen atom, an alkoxy, alkylamino, cycloalkylamino, phenylamino or aliphatic acylamino group, (b) a 1:5 or 1:8-diarylmercapto anthraquinone or (c) a 1-amino4-arylmercapto anthraquinone having in the 2- position an alkyl, alkoxy, arylmercapto or cyano group or a halogen atom; the dyestuffs being free from water-solubilizing groups such as -SO3H and -COOH groups. The arylmercapto groups may be a - or b -naphthylmercapto and expecially phenylmercapto groups of which the phenyl group may contain substituents such as halogen atoms, lower alkyl, hydroxyalkyl, alkoxyalkyl, alkoxy, hydroxyl, amino, nitro, cyano or carbalkoxy groups.  The dyestuffs may be obtained by reacting a nitro- or halogen-anthraquinone with an arylmercaptan by a known method.  Mixtures of two or more of the above dyes may be used.  The dyestuffs may be applied in the form of an aqueous dispersion and, in the case of polyethylene terephthalate fibres, in the presence of a carrier or at a temperature of 120 DEG C. under pressure from a slightly acid bath. Alternatively the fibres may be impregnated below 60 DEG C. and subjected to thermofixation at 180 DEG -210 DEG C., it being of advantage to dry the fibres previously.  Printing may be accomplished with a thickened paste which may contain other usual additives.  Mixed fabrics of aromatic polyester and cotton may be dyed or printed with a paste or padding liquor containing in addition a direct, vat or reactive dyestuff.  Mixed fabrics of polyester and wool may be dyed whereby the wool portion remains reserved and may subsequently be dyed with a wool dyestuff.  Examples of preparing dyestuffs and of dyeing and printing are given in which the following dyestuffs are specified: 1-phenylmercapto anthraquinone, 1-methylamino-4-phenylmercapto anthraquinone, 1:5-diphenylmercapto anthraquinone, 1-amino2:4-diphenylmercapto anthraquinone, 1-amino2-methyl-4-phenylmercapto anthraquinone, 1amino-2-bromo-4-phenylmercapto anthraquinone, 1-amino-2-cyano-4-phenylmercapto anthraquinone, 1-amino-2-(b -methoxyethoxy)-4-phenylmercapto anthraquinone, 1-anilino-4-phenylmercapto anthraquinone, 1-acetylamino-4-p-tolylmercapto anthraquinone and 1-(p-dim-ethylaminophenyl)-mercapto anthraquinone.

Abstract: 1358801 Automatic voltage control BURROUGHS CORP 28 Jan 1972 [10 Feb 1971] 4064/72 Heading G3R In a regulated power supply, a series impedance is varied in response to a control current produced by a comparator receiving a reference voltage from a battery, and a second voltage indicative of the voltage supplied to a load. In the circuit shown in Fig. 2, a load 12 is supplied from an A.C. source 18 over a transformer 20 and rectifier 28, 30, and is connected in series with a transistor 62. Also connected across the rectified supply is a battery 52 with an associated charge control unit 54. In operation, when a switch 76 is closed, a coil 46 receives sufficient current from an auxiliary transformer winding 26 to close a reed switch 72 through which current may flow to the base of control transistor 62. The magnitude of the base current is determined by the output of a differential amplifier 94 which receives a signal proportional to the load voltage from a divider 88, 90 for comparison with a reference voltage across a Zener diode 82 connected across the battery 52. The transistor 62 regulates the output voltage between predetermined limits. If the A. C. supply fails, the load continues to be energized by the battery 52, until its voltage drops to a value at which the current in the coil 46 is insufficient to hold the switch 72 closed, whereupon the transistor 62 is turned off. The Zener diode 82 and resistor 78 provide a high resistance discharge path for the battery 52 which permits deep discharge during periods of non-use to overcome losses caused by cycling in nickel-cadmium cells.

Abstract: 328,351. Welsh, A. Feb. 7, 1929. Regulating or controlling.-The angle of the blades A of a fan-type impeller for supplying the charge to the cylinders of an internal combustion engine may be varied to control the delivery pressure of the charge. An engine-drive shaft K, supported between ball races U, rotates a hubmember B which is divided to accommodate within it two circular blade root members R. Each blade root R carries a pin E<1> fitted eccentrically and engaging with slotted holes E formed in a cross-head which is capable of movement in the direction of the shaft axis. A co-axial shaft D controls the sliding movement of the cross-head, the opposite end of the shaft being provided with a thrust bearing S and control arm X. As the cross-head moves between the blade roots the engaging pins cause the blades to rotate in their sockets. Diametrically opposed ports T and F form the inlet and outlet orifices respectively and they are so shaped that when the blade angle is reversed between zero and 45‹, a partial vacuum is created in the induction pipe H. When at their maximum angle the blades admit the charge only as they pass the ports T, F.

Abstract: 1,022,906. Screening apparatus. W. CUTLER. Jan. 18, 1965 [Jan. 31, 1964], No. 4098/64. Heading B2H. In a machine for grading articles according to size and comprising a vibratory grading screen 10, Fig. 1, a device 14 for dislodging any articles that have become stuck in the screen is pivotally mounted below the screen and is adapted upon pivotal movement to move into close proximity with the undersurface of the screen, the arrangement being such that the vibratory movement of the screen relative to a fixed part of the apparatus operates to cause the device 14 to swing about its pivotal axis thereby causing it to come into close proximity with the undersurface of the screen. Due to the vibration the grading screen, the articles to be graded are caused to travel along the screen, those articles which do not fall through the screen being caused to travel to another grading section or to a discharge outlet. The grading screen which may consist of a perforated sheet of metal or fabric or of spaced elongated parallel bars, is carried above a fixed base frame 12 of the apparatus by means of resilient slats and is vibrated by an eccentric drive. The device 14 comprises a perforated steel mesh 16 extending substantially the full width of the screen and mounted on rollers 18, 20, 22 mounted on a pair of plates 24 disposed one on either side of the screen. The plates 24 are secured to a shaft 26 mounted at either end in bearings 28 provided on plates 30 forming parts of brackets engaging guide frames 34 and vertically adjustable relative to the base frame 12 by means of set pins 36. The shaft 26 has rigidly secured, adjacent each end thereof, a lever 56, Fig. 2 (not shown), provided at its lower end with a plate 58 which is disposed between a pair of rubber buffers 60. In one arrangement, the device 14 is vibrated by the same prime mover in synchronization with the screen 10 and the buffers 60 are fixed relative to the frame 12 so that, as the device 14 is vibrated, the plate 58 contacts the buffers 60 to cause the lever 56 to effect rotation of the shaft 26 and hence to cause the plates 24 and mesh 16 to pivot about the shaft axis. In another arrangement, the buffers 60 are coupled to the eccentric drive for vibration with the screen 10 and thereby cause the plate 58 and hence the mesh 16 to pivot about the axis of the shaft 26 on engaging the plate 58. During pivotal movement of the mesh 16 articles which have passed through the screen and are supported by the mesh are thrown upwards to strike the undersurface of the screen 10 and to dislodge particles which have become stuck therein.

[Class 39 (i).] In an arrangement for reducing the quantity of vapour in front of the anodes by varying the size of the cathode spot e in accordance with the load, by means of a piston l which is operated by the arc current to regulate the flow of mercury in a pipe f between the cathode vessel o and a mercury container g, the vessel o is of conical shape and of such dimensions that there is always only sufficient mercury therein to form a surface corresponding to the size of the cathode spot. As shown in Fig. 1, a copper or iron closing plate c, provided with a cooler d, is secured to the casing by an insulator b, and supports the cathode vessel, which is formed of refractory metal such as tungsten, molybdenum or tantalum, or of heat-conducting metal lined with a refractory metal. To improve heat conduction, a copper layer may be inserted between the cathode vessel and the plate c when the latter consists of iron. The cathode vessel may consist of segmental pieces x and the cooling medium therefor should then consist of mercury. A conical insertion h of quartz or chamotte prevents the cathode spot from wandering to the casing. Condensate is collected in a gutter i and is returned to the pipe f through a pipe k which is provided with a valve n to prevent oscillations in the mercury column. The piston l is controlled by the solenoid m to act on the elastic wall of the vessel g. In a modification, the cathode closing plate consists of a vessel p, Fig. 2, containing cooling mercury, the level of which is higher than that of the cathode. A cooling coil s is mounted in the condensation space of the vessel which may be connected with the interior of the rectifier by a cooled passage ; the vacuumtight joint between the members o, h is then superfluous.
