Title: Bobbin feeding devices
IPC: D01H9/18
Filed: 1973-02-12
Abstract: 1374061 Supplying bobbins to spinning machines HEBERLEIN HISPANO SA 12 Feb 1973 [25 Feb 1972] 6797/73 Heading D1F Empty bobbins 6 are transferred e.g. from a magazine 7, to an automatic changing apparatus 1 which serves a textile machine (not shown) and carries the bobbins one on each of a series of hooks 4 spaced (according to the distances between the machine spindles) along an endless conveyor 2. The feed apparatus orients the bobbins so that the heads thereof are uppermost and delivers single bobbins in succession onto a tiltable element 14 which transfers each bobbin from the position shown in Fig. 1 to a position, Fig. 4, in which it is presented with its head 5 in the path of a hook 4. In preparation for a loading operation, conveyor 1 is disconnected from its normal drive and flexibly coupled to an auxiliary motor 34 so as to be driven at a slow speed. An empty bobbin 6, supplied by stepwise operation of a cup elevator 11 and oriented by a mechanism 8, falls into channel 13 and passes to element 14 forming an extension thereof. A pneumatic cylinder and piston mechanism 16 operates to tilt element 14 about pivot shaft 15 whereupon a stop element 18 cooperates with a fixed ramp (19) to oppose the upward bias of a blade spring 17 until the final stage of presentation of the bobbin, an pneumatically operated bolt 30 maintains the bobbin in position, and a projection 14a disengages a lever 28 to allow a spring 29 to move a retaining pin 27 into channel 13 where it holds another bobbin 6 in readiness for the next cycle of operations. When the delivered bobbin is received by a hook 4, the bolt 30 is withdrawn and the emptied element 14 retracts to initial position where it receives a bobbin 6 released by pin 27. Operation of pneumatic components is controlled by a distributor 37, fed by a compressed air source 38 and receiving signals e.g. electromagnetic, from detectors such as 39 (recognising the passage of a hook 4) and 41 (recognising the presence of a bobbin 6 in channel 13 ready for transfer and the absence of a second bobbin thereabove).

Abstract: 453,502. Controlling flow of fluids; furnaces; burners. GERRARD, C. W. G., 37, Tavistock Square, London. March 11, 1935, No. 7575. [Class 135] [See also Groups XI and XII] In order to obtain a sensitive control of the flow of a fluid (such as the air supply in furnaces for normalizing or annealing steel, or pulverized coal in suspension in air) with a constant maximum velocity of discharge for all rates of flow, the pipe or duct which may be circular or rectangular in section is divided, as by partitions, from the controlling means to the point of discharge, into a plurality of ducts which are separately controlled and some at least of which are of different cross-sectional areas. By opening different selections of the ducts, singly or in combination, a large number of regulations may be obtained. The relative areas of the ducts are preferably in geometrical progression. The controlling means may be valves, baffles, dampers, sluice gates, or water seals, and may be arranged remote from the discharge end enabling the ducts at their discharge ends to be constructed of heat resisting material such as steel, fire-brick, or carborundum. Valves may be operated in order by cams on a shaft which carries also an indicating pointer. Fig. 1 shows a pipe a, leading secondary air to a boiler furnace, divided into a central and two annular ducts c<1>, d<1>, e<1> of different areas. Fig. 3 shows three ducts c, d, e, in multiple and proportioned 2, 4, 8 to yield seven regulations, respectively controlled by baffle valves i, j, k actuated by rods l, m, n, Fig. 5, carrying indications o<1> appearing at windows o. Stationary indications p set out the combinations required for the various regulations. The discharge orifices may be of less area than the ducts and may have vanes to give a whirling motion to the fluid. Fig. 8 shows the gas supply at s and the air supply at v led to a circular burner t through concentric annular ducts controlled respectively by valves u, w. Instead of regulating stepby-step, the flow may be regulated progressively between a minimum and a maximum by operating one of the valves as a throttle valve.
