A/The nozzle comprises a conduit 2 within which is a turbine assembly adapted to be rotated by a gas stream, the assembly including a central member 7 which has a projecting shaft portion 6 on which the turbine wheel 3 is rotatable, said turbine wheel carrying blades 4 and liquid conduits or tubes 19 around its periphery. The orifices of the tubes 19 end opposite the face of a shoulder 20 on the member 7, the clearance being relatively small so that the shoulder acts as a shield. The cross member on which the central member 7 is mounted is tubular and its interior is connected by an axial bore 10 with a transverse bore 17 in the member 7, which in turn is open to an annular cavity 18 in the turbine wheel 3. A stream of gas from a blower enters the nozzle at 25 and flows over the central member 7, guided by a coaxial duct. 22 and the streamlined end 21 of the member, and causes the turbine wheel 3 to revolve. Liquid is fed from a reservoir to the interior 9 of the tubular member and emerges from the tubes 19 under centrifugal action. Since the orifices are moving very fast through the gas in their own plane, fine particles are torn off from the film of liquid presented at the orifice, thereby creating an aerosol which is carried through the outlet 2a by the gas stream. The flow of liquid is controlled by a valve rod 15 operated by a knob 16.

Filed: 1973-05-24
Abstract: 1374230 Braking yarn packages W H K PRODUCTS Ltd 24 May 1973 24925/73 Heading D1J A yarn package 14, and a drum 16 are both freely rotatable on a spindle 12. A spring in the drum 16 couples the package 14 to the drum 16. A friction pad 17 on a load carrying arm 18 rests on the drum 16. In use, as yarn is drawn from the package 14, the spring is wound up until the force in the spring overcomes the friction between the pad 17 and the drum 16. As the package is unwound, if the yarn temporarily becomes slack, the coil spring will unwind by an amount sufficient to take up the slack. The arm 18 is pivoted at one end and as unwinding proceeds the pivot point is gradually displaced such that the arm 18 and pad 17 are displaced around the drum 16 in a manner reducing the braking effect exerted by the pad 17. As shown in Fig. 1 the arm 18 is pivoted on a slide bar 19 that is moved axially by threaded means driven by gear wheels 22, 23. Stop motion. When the machine is to be stopped a further brake 28 is applied. The brake 28 is on an arm 26 pivoted at one end on the frame 10. The other end rests on a spring 30 on a rod 27.

Title: A new or improved process for the recovery of zinc from dross
Inventor: HUGHES MARTIN LUTHER
IPC: C22B7/04
Filed: 1952-10-06
Abstract: A method of recovering Zn entangled in the dross from a galvanizing bath comprises reacting the dross with Al or an Al alloy, such as Al-Si, where Si=5 per cent, to form an Al-Fe alloy and free the combined Zn, simultaneously or subsequently dissolving the Zn in molten Pb at high temperature, and then cooling the Pb to throw the Zn out of solution.  Preferably, to a bath of molten Pb at a temperature of 350-400 DEG  C. is added an amount of dross equal to about 10 per cent of the weight of the Pb, together with an amount of Al equal to about 1 1/2 times the weight of Fe in the dross.  The temperature of the bath is then raised to above 700 DEG  C., the Al-Fe alloy formed is swept aside or removed from the surface of the bath, the bath is cooled to below 420 DEG  C., and the solid Zn, which separates out on top of the still molten Pb, is removed.  This final removal may be effected by lowering into the bath of molten metal a steel frame partly open at the top and bottom, the walls of the frame extending above and below the surface of the bath, transferring molten Zn on the bath surface outside the walls to within the frame and, subsequent to the freezing of the Zn, lifting the frame with the cake of solid Zn within it out of the bath.

Abstract: 316,275. Bakelite Corporation, (Assignees of Chamberlin, C. L.). July 27, 1928, [Convention date]. Fibrous plastic compositions.-A dry composition capable of flowing in the mould is composed of pieces of woven fabric, for instance coutil, impregnated with a fusible resinous binder, for instance a phenol aldehyde resin in the reactive state. The size of the pieces of fabric may vary from # inch to 1¢ inches long by # inch to 1¢ inches wide. Colours or coloured compositions such as wood flour mixes, may be added, but not coarse filling material of the nature of ground cork. In an example, coutil is cut into pieces in a rag cutter to sizes of about 1 to 1¢ inches long by 1 to 1¢ inches wide. The pieces are placed in a kneading machine and a 50 per cent solution in alcohol of the reaction product of about 100 parts of phenol, 60 parts of formaldehyde and 10 parts of hexamethylenetetramine is added. After mixing for about 20 minutes the material is dried under a partial vacuum at about 70C and remains in flake form. For the moulding of articles, a hot mould is charged with the loose material and pressure is applied. Continued heating at about 135C hardens the resin. Specification 146,845 is referred to.

Filed: 1962-06-29
Abstract: 934,337. Coin-freed apparatus. H. HOPKINS. June 29, 1962, No. 25159/62. Class 27. A coin-operated device for controlling the use of electrical devices, such as television or radio sets and lighting and heating units, for a succession of units of time comprises a switch 23 connected to a synchronous motor 34 for driving one gear 15 of a differential gear, another gear 14 of which is driven by a rotatable coin-holding device 8, 10, a cam-wheel 19 rotated by the spindle 17 of the differential gear, a slotted disc 22 rotated by gearing 18, 20 from this spindle, a pivoted arm 25 controlling switch 23 and carrying two pins 27, 28 bearing against the cam wheel and slotted disc, respectively, and a stop device 42 operated by the slotted disc after the insertion of a predetermined number of coins to lock the coin-holding device and protect the mechanism from damage. The coin-holding device consists of a semi-cylindrical sleeve 10 which is secured to a spindle 6 carrying a knob 5 and receives a cone 8 on a spindle 7. The sleeve and cone have slots 9 which, when lined up, receive a coin inserted through a slot in a front plate 1 so that rotation of the knob is transmitted to the spindle 7 to impart rotation through a gear 13 to the gear 14 of the differential. Rotation of the gear 14 turns a jockey wheel 16 so as to rotate a spindle 17 carrying the cam wheel 19 and a gear 18 engaging a gear 20 on a shaft carrying the slotted disc 22. The rotation of the spindle causes the cam wheel to move the arm 25 about a pivot 26, the arm moving a second arm 24 to close the switch 23 so that the electrical device may be used by the consumer. The closing of the switch also starts the motor 34 which is connected by reduction gearing 38, 39, 40 to the second gear 15 of the differential which is rotated to return the jockey wheel 16 and spindle 17 back towards their initial positions, which, for the insertion of a single coin, may take 30 minutes. When the initial position is reached, the pins engage the flat on the cam and the slot so that the arms return the switch to the open position. The gearing between shafts 17 and 21 may be in the ratio of 6: 1 and the rotation imparted to shaft 17 and cam 19 upon insertion of a single coin is equal to about one-third of a revolution. Additional coins may be inserted in the device, the shafts rotating by corresponding amounts, up to a maximum of 17 coins whereupon a bar 41 on the disc 22, which will now have rotated almost one revolution, pivots an arm 42 so that it engages a transverse slot in the core 8 to prevent further insertion of coins. A counter 29 driven from the gear 13 records the number of coins inserted in the device.
