Title: Method and apparatus for producing yarn packages with a variable speed spindle
IPC: D01H1/30
Filed: 1967-03-17
Abstract: The growth of a package of yarn on a spindle, e.g. a ring spindle, is controlled by driving the winding spindle at a rotary speed equal to the product of the feed rate of the yarn and a programme signal representative of the rotary speed at a particular feed rate. As shown, a pulse source 3 is coupled to a draw roller and emits pulses having a repetition frequency proportional to the rotary speed of the draw roller. The pulses are fed to adjustable-ratio pulse dividers 4, 5. The pulse-divider 4 is adjusted by hand and its output is applied to a stepping motor 6, the shaft of which is coupled to a programming unit 7. The frequency division of pulse-divider 5 is adjusted in dependence on the output from the programming unit, which comprises a programme card having ridges co-operating with micro-switches, which is displaced by the stepping motor 6. The repetition rate of the programme-adjusted pulses from the pulsedivider 5 are compared in a comparator 9, forming part of an automatic speed controller 10, with the repetition rate of pulses from a pulse source 8 emitting pulses having a repetition frequency proportional to the rotary speed of a yarn-winding spindle 2, whereby the speed of the spindle is maintained in correspondence with the draw-rate. The pulses from pulse-divider 4 are also fed to adjustable pulse-dividers 11, 12 the ratios of which are set by the programming unit 7. The pulses from the pulse-dividers 11, 12 are applied to stepping motors 13, 14 rotating spindles 15, 16 positioning slides 17, 18 on which switches 19, 20 are mounted. The switches co-operate with a projection 22 on a rod 21, which is moved with a ring rail or spindle-carrying bar, to reverse the transverse motion and determine the build-up of a package on the spindle 2.

Title: Continuous method of and apparatus for making bars from powdered metal
IPC: B22F3/00
Filed: 1976-09-03
Abstract: Powdered metal is continuously introduced into a horizontally disposed die cavity in discrete quantities and compacted into bar segments to form a bar. The cavity has a fixed cross-sectional area and is open at both ends, except during the initial compaction when one end is closed. After formation of an initial length of the bar, the frictional resistance between the length of bar remaining in the cavity and the cavity wall is relied on so that the length of bar remaining in the cavity serves as a stopper for subsequent compactions of the discrete quantities of powdered metal. The bar is forced out of the cavity upon the formation of subsequent segments and is passed through an induction furnace for sintering, and may be further processed through a swager, all preferably in a continuous operation. Also provided is means for varying the quantity of powdered metal introduced into the die cavity so that the bar lengths formed from the discrete quantites of powdered metal are compacted and bonded into a bar of substantially uniform physical characteristics along its length.
Patent ES-451955-A1 (ES)
Title: Carbon separation
IPC: B01D17/025
Filed: 1976-09-29
Abstract: This is a process and apparatus for continuously separating a liquid mixture comprising particulate carbon produced by the partial oxidation of a hydrocarbonaceous fuel, water, and liquid organic extractant into two separate immiscible streams i.e. a stream of particulate carbon-liquid organic extractant dispersion and a separate stream of clarified water. The subject apparatus may be referred to as a carbon decanter and comprises a closed pressure vessel whose horizontal cross-section is circular. Thus, the decanter may be shaped like a vertical cylinder or may be spherical shaped with discharge ports in the top and bottom. The liquid mixture of particulate carbon, water, and liquid organic extractant is charged into said vessel by way of a conduit which terminates at a position within the vessel along the vertical axis about 1/4 to 3/4 of the vessel height and below the interface level which is formed in said vessel when the two immiscible liquids separate by gravity with the water forming a pool at the bottom of the vessel. Alternately, the decanter may be charged through two concentric pipes. A horizontal radial nozzle terminates each pipe. By this means the aforesaid mixture of immiscible liquids may be introduced into the decanter by way of an annular passage located between said pipes. Further, simultaneously a separate stream of liquid organic extractant may be passed through the center pipe and discharged adjacent to the interface level. The dispersion of particulate carbon-liquid organic extractant separates from the water and may be removed by way of the top port as a continuous stream. Simultaneously a continuous stream of clarified water may be removed from the bottom port.
