Abstract: 1,234,202. Doffing winding machines. ERNEST SCRAGG & SONS Ltd. 24 Sept., 1968 [27 Sept., 1967], No. 43917/67. Addition to 1,200,455. Heading D1J. In the doffing apparatus according to claim 7 of the parent Specification wherein a pair of auxiliary drive rollers are used to cradle a full spool after its release from contact with a main drive roll, the pair of auxiliary drive rollers are movable downwardly together to lower the spool onto a conveyor after severing the yarn. As shown, auxiliary drive rollers 118 are carried by arms 121 which swing downwardly towards the delivery conveyor 119 prior to their releasing the full spool. The arms are rockably supported on rotatively driven shafts 122 which carry pulleys 126 for driving belts 127 by which the rollers are driven. The arms 121 are rocked through toothed sectors 123 meshing with sectors 124 mounted on rocking shafts 125. The magazine 145 for storage of empty spools has catch means at its delivery mouth which are operated when transfer arms 161 for picking up the spool reach the pick up position. The catch means consists of a first detent 158 which holds the empty spools back clear of a counter balanced locating lip 157, and a second detent 159 which, as detent 158 swings to allow a spool to move to lip 157, itself moves into the path of the next spool. The detents may be directly actuated by the transfer arms 161, or at an appropriate time in a batch doffing cycle. The plate 130 for guiding into a desired path yarn travelling towards a full spool being driven by rollers 118, has a transverselydisposed arcuate slot 131, and above the slot an arcuate, resilient, guide wire 132 with a mid length notch 133. The yarn is caught in the notch as it travels along the guide wire due to the motion of the traversing yarn guide. A severing device located beneath the plate then cuts the yarn. Deflector panels 150, swingably suspended, assist delivery of the released full spool to the auxiliary roll drive, the panels having associated with them weighting bars adjustable to vary the guiding effect of the panels.

Abstract: 1,256,564. Hydraulic turbines - controlling. HITACHI Ltd. Feb. 20, 1969 [Feb. 21, 1968 (2)], No.9372/69. Heading F1T. The invention relates to a method of controlling a water shut-off valve in a Francis turbine upon interruption of the load at which the turbine has been operating, the method comprising closing the shut-off valve only after it has been held open at the amount of opening at the time of interruption of the load for a predetermined time from the time of interruption of the load. A turbine control system is shown in Fig. 6 the system comprising a governor A which normally controls supply of pressure oil through a distribution valve B and a normally open shut-off valve C to a servomotor D which controls opening of the shut-off valve E. The position of the servomotor is fed back to the distribution valve B. Upon interruption or loss of load detected by the sensing means F signals are transmitted to the valve C which is shut-off, and to the time-limit change-over valve H which is energized so that after a predetermined delay it opens to allow pressure oil to pass through the throttle valve G to operate the servomotor D in a closing direction whereby the water shut-off valve E is closed. In a second embodiment Fig. 7, operation of the detecting means F upon load interruption causes the shut-off valve C to close as before rendering the governor A ineffective. At the same time the valve J is opened allowing pressure oil to pass to changeover valve I which allows oil to actuate the servomotor D in an opening direction whereby the opening of the water shut-off valve E is increased. The opening of the valve E is sensed by the detecting means L and when a predetermined opening is attained a signal is transmitted to the change-over valve I and pressure oil is now stopped so that the shut-off valve E remains open at the increased opening. After a predetermined time interval from interruption of load as determined by time limit relay K, the change-over valve I is operated so that pressure oil is now passed to operate the servomotor D in a closing direction whereby the water shut-off valve E is closed. In Fig. 8 interruption of load sensed by detector F again closes the pressure oil shut-off valve C and simultaneously opens valve J whereby pressure oil flows through throttle valve G<SP>I</SP> to cause servomotor D to move in the opening direction whereby the opening of the water shut-off valve E is increased. The opening is sensed by the detector L and when a predetermined opening is attained the changeover valve I is operated whereby pressure oil now passes through throttle valve G and operates the servomotor D in a closing direction so closing the water shut-off valve E.

A continuously wrapped yarn comprises a continuous core element having a plurality of series of separate continuous wrapping elements with each series comprising wrapping units in an overlapped spatial relationship along the length of the yarn, each wrapping unit comprising a continuous wrapping element having a varying wrapping frequency forming a first layer of wrappings in helical configuration having a predominantly unidirectional twist, a tight overwrapped segment formed of said continuous element backwrapped over a portion of said first layer with at least a part of said overwrapped segment having a wrapping direction of rotation opposite to that of said first layer. A process for producing a wrapped yarn includes the steps of continuously advancing a continuous core element 1, twisting the element with means 4 to form a balloon 6 immediately upstream of the twisting means, and feeding two or more continuous wrapping elements 7 to wrap about the rotating balloon portion of the core, a standing wave pattern of multiple balloons being formed in the core element by controlling the tension therein while guiding the core with means spaced a sufficient distance from the twisting means to form the wave pattern; and separate continuous wrapping elements being wrapped about separate balloons by freely feeding the wrapping elements to the balloons to form the wrapped yarn. The wrapping elements are fed to the balloons upstream of the twisting means which may be a fluid twister or a mechanical false twister. The core element may be formed from a plurality of separate continuous elements brought together to form a bundle or may comprise a continuous element formed of discontinuous elements. Similarly each of the wrapping elements may comprise discontinuous elements or a bundle of continuous elements. Suitable materials are polyesters or polyamides, or polypropylene. The wrapping elements are preferably fed at right angles to the direction of travel of the core element.

The centrifuges 1, 2 have motor control panels 7, 8 associated therewith. Valves S 1 , S 2  control the entry, into the respective centrifuge, of liquid (e.g. oil) and sludge mixture coming from a reservoir 3 via a pre-heater 12. Valves S 3 , S 4  supply displacement liquid to the centrifugal chambers of the drums of the centrifuges and they only open, when the respective centrifuge is acting as a separator, for a short time just prior before removal of the sludge so that the displacement liquid effects complete removal from the centrifuges of the useful liquid component, e.g. oil. Valves S 5 , S 6  supply controlling fluid, at the time of complete or partial removal of the sludge from the centrifuges, to control chambers of the centrifuges, as a result of which a contactor bar is lowered and opens the sludge exits; after sludge removal, valve S 5 , S 6  close and controlling fluid is forced out of the control chambers by centrifugal force, whereafter the bar closes up the sludge exits again. The centrifuges are interconnected by means of a three-way cock 5 and an insulated pipe 4. After clarification in centrifuge 2 the purified liquid is conducted to a reservoir 13 for further use. When a fault occurs in the two-stage separator, control devices 6 pass a signal to the motor control panels 7, 8. The signal may also initiate a complete or partial sludge removal in both centrifuges to eliminate the trouble; if sludge removal does not lead to elimination, both centrifuges I and 2 are switched off, the valves S 1 , S 3 , S 5 , and S 6  are closed and an alarm is initiated. Signal lights h 1 , h 2 , and h 3 , indicate whether the centrifuges are working as separators and/or clarifiers.
