Abstract: 728,096. Washing-machines. KURE, G. Jan. 23, 1953 [Feb. 15, 1952], No. 1990/53. Class 138 (2). A washing-machine comprising a continuously rotating agitator located adjacent to the wall, bottom or lid of a washing container, is provided with a flow guiding member comprising a disc or ring disposed coaxially with the agitator and provided with a guide blade or baffle whereby the current flow of washing liquid changes its direction periodically. In one example, Fig. 1, the flow guiding member comprises a disc 5 having a smoothly curved guide blade 6 which partly encompasses the agitator 4, the disc 5 rotating at a slower speed than the agitator. The disc 5 may have protrusions or ribs 7 so that the currents set up in the liquid by the agitator 4 impart a slow rotation to the disc 5. In a modification, both the agitator and the flow guiding member are driven by an electric motor which is connected to the flow guiding member through reduction gearing. Alternatively, the flow guiding member and agitator may be provided with ribs which form a liquid coupling between the two members. In a further alternative the flow guiding member is journalled on the agitator shaft, but driven by the friction between it and the shaft. In Fig. 5, the flow guiding member is formed as a ring 25 provided with a guide blade 26, and is journalled as shown to be rotatable about the circumference of the agitator 24. The agitator may be apertured as at 21. In Fig. 3 (not shown), the agitator has radial vanes on both sides and rotates in a recess in the bottom of the container.

IPC: B65G53/46
Filed: 1966-01-18
Abstract: 1,067,532. Pneumatic conveyers. POLYSIUS G.m.b.H. Jan. 18, 1966, No. 2229/66. Heading B8A. A device for the continuous pneumatic feed of powdered or granular material comprises six pressure containers 9 mounted in a body 2 which is adapted to be rotated, through. gearing 24, 25, around a fixed vertical column 1 formed with a main compressed-air conduit 32 and with a material feed pipe 31. Each container 9 is provided with a material inlet 12, which is at the base of a common hopper 11 formed in the body 2 and which is closable by a valve 13, a compressed-air inlet 33 leading to the space beneath a porous floor 10 and a material exit pipe 30. The valves 13 are actuated by pistons 15 controlled by compressed air from pipes 38 and by springs 17, the arrangement being such that during a portion of the angular movement of the body 2, compressedair is supplied to one of the cylinders 16 to open the associated valve 13 to allow material to fall into the associated container 9. Continued rotation of the body 2 then connects the pipe 38 to an exhaust conduit and the spring 17 closes the valve 13. Further rotation of the body 2 causes the air inlet 33 to be connected to the main conduit 32 to pressurize the container 9 and the material outlet pipe 30 to be connected to the material feed pipe 31, whereby the material is extracted. The cycle is repeated with the other five containers 9 and since there is always one partly filled container 9 connected to the material outlet 31 there is a continuous feed of the material. The output of the device can be varied by varying the speed of rotation of the body 2 and the stream of air through an auxiliary conduit 34 into the pipe 31.

Title: Manufacture of sulphurised derivatives of phenols and naphthols and their application as mordants
IPC: C14C3/20
Filed: 1926-01-26
Abstract: 269,970. Fabriek van Chemische Producten, and Kraus, E. Jan. 26, 1926. Sulphurizd derivatives of phenols and naphthols which act as mordants for basic dyestuffs or as reserves in dyeing textiles are obtained by heating a dry alkali metal salt of a phenolic body or a naphthol with sulphur in a non-aqueous medium, preferably a phenol itself, in which the phenolate is suspended or dissolved. The phenolic body may be a cresol, xylenol or a chlorophenol. If phenol is used as the medium it takes part in the reaction and should be in the proportion of less than four equivalents of free phenol to each equivalent of alkali phenolate,. The product so obtained may be treated with an aldehyde and a sulphite giving products which are also useful for mordanting and for tanning. purposes. The quantity of sulphur is preferably between 1 and 2 atomic proportions for every molecular proportion of phenol. In examples, (1) sulphur is added to sodium phenolate in phenol and the mixture is heated. The properties of the final product vary with the quantity of sulphur used; (2) sulphur is added to sodium phenolate suspended in solvent naphtha and the mixture is boiled. After removal of the naphtha the sulphurized product is precipitated by acid; (3) the product obtained in the first example is stirred with water, sodium sulphite and formaldehyde or acetaldehyde added, and the mixture heated. The solution obtained may be used directly after neutralization for tanning or the reaction product may be salted out. An alkaline solution of the reaction product may be used as a mordant for fixing basic dyestuffs on cotton &c. or as a reserve. Instead of phenol commercial cresol or one of the isomeric cresols or mixtures thereof with ordinary phenol may be used; (4) #-naphthol and phenol are melted together, caustic soda and sulphur are added and the mixture heated. The reaction product is treated with sodium sulphite and formaldehyde as before.

Jan. 22, 1930, No. 2287. Convention date, Feb. 11, 1929. Void [Published under Sect. 91 of the Acts]. [Class 100 (i).] Registering webs transversely and longitudinally.- In a machine for cutting sheets from a web of paper or other material bearing watermarks or other markings, means are provided for adjusting the web laterally and longitudinally so that the markings are positioned accurately with respect to the edges of the sheets. The web is fed from the roll 1 to the cutters 20 by feed rollers 8, 9 driven by friction discs 11, 12. Between the roll and the feed rollers, the web is illuminated by a lamp 6 to facilitate the observation of the watermark, and lateral register of the web is effected by moving the roll 1 axially by means of a handlever 7. The edges of the web are trimmed by slitters 15, 16. A second observer, aided by a lamp 24, inspects the web for deviations of longitudinal register and effects corrections by turning a hand-wheel 31 which, through a cam 33 and arm 35, adjusts a pair of guide rollers 18 to retard or advance the web. Large errors of longitudinal register are corrected by an adjustment of the speed of the feed rollers 8, 9. For this purpose the shaft of the hand-wheel 31 is geared to a quadrant 38 carrying a pin 39 extending between adjustable stops 42, 43 carried by a lever 41. For small movements of the hand-wheel the pin 39 moves idly between the stops 42, 43, but for larger movements, the pin 39 moves the lever 41, which by means of a cam 44 and arms 46, 48, 49 moves the friction disc 12 nearer to or further from the axis of the disc 11. The arm 46 is loose upon the shaft 47 to which the arms 48, 49 are fixed and is connected, to the arm 48 by a worm 51 by which the disc 12 can be adjusted independently of the hand-wheel 31. Sheet-delivery apparatus.-Faulty sheets and perfect sheets are delivered to separate tables 29, 30, the sheets being directed to the correct table by a switch 28 operated by a hand-lever 27.
