Title: Textile drafting mechanism
IPC: D01H5/50
Filed: 1956-11-22
Abstract: 792,126. Drafting mechanism. SACOLOWELL SHOPS. Nov. 22, 1956 [Dec. 19, 1955], No. 35726/56. Addition to 792,090. Class 120(2) Drafting mechanism as claimed in the parent Specification is characterized in that the resilient loading means comprises coil springs and further in that means are provided for correcting side force producing errors of the spring loading means causing lateral misalignment of the arms. As shown the correcting means is in the form of a washer 36 having a slanted or wedge-shaped upper surface for engaging the loading spring 34. The washer 36 can be rotated by a special tool engaging a hole 46 in the washer so as to produce a side force to counteract any side force caused by inaccuracies in manufacture of the parts. In a second embodiment the washer instead of having a slanted surface is provided with an eccentric portion so that the bottom of the spring can be displaced laterally with respect to its top thus producing a side-ways force.

Filed: 1960-10-19
Abstract: <PICT:0910055/III/1> A mixture of ethylbenzene and ortho-/metaxylenes together with closely-boiling hydrocarbons is separated into two fractions and, at the same time, steam at a pressure of at least 20 p.s.i.g. is produced in apparatus comprising a fractionating column 24 which is heated by heater 28, control-devices for maintaining the pressure within the column above 23 p.s.i.g., and three heat-exchangers 20, 22, 36, the first two heat-exchangers being employed to preheat the hydrocarbon-feed before it is pumped into p the column, while heat-exchanger 36 is used for condensing the overhead vapour from the column (i.e. the ethylbenzene fraction) and also for raising steam.  In heat-exchangers 20 and 22 the feed is heated by part of the condensate and by the bottoms product (i.e. the xylene fraction), respectively.  The water-feed for heat-exchanger 36 is introduced into steam/water separator 50, the rate of supply being controlled by valve 52 which in turn is controlled by constant-level device 54.  The water is pumped from separator 50 to heat-exchanger 36 through valve 58 which is controlled by regulator 60 responsive to the vapour-pressure in reflux and heads-product accumulator 38.  The pressure in column 24 is also controlled by valve 58.  The steam generated in exchanger 36 is returned to separator 50, whence it is withdrawn as needed for industrial purposes.  Control 30 actuated by the pressure-differential between spaced plates of column 24 is provided for controlling the valve 32 which controls the input of fuel to heater 28.  The quantity of overhead fraction withdrawn from the system is controlled by constant-level control device 48 connected to accumulator 38.

Title: Fluid flow control valve
IPC: F16K31/163
Filed: 1964-09-10
Abstract: 1,046,663. Valves. GROVE VALVE & REGULATOR CO. Sept. 10, 1964 [Oct. 2, 1963], No. 37107/64. Heading F2V. A rotary disc valve, wherein the closure member is adapted to be moved axially toward or away from the seat during closing or opening respectively, comprises in the embodiment of Figs. 1 and 2, a closure member 20 carried by a member 22 rotatably mounted on a spindle 23 and guided for movement between the side plates 12, 12a of the valve by means of a roller 36. In operation from the closed position of Fig. 1, initial anti-clockwise rotation of the operating spindle 23 rotates, via links 50-52, a member 40 threaded to member 22 and thereby causes the closure member to lift from the seating 18. At the same time, the rotating link 50 moves, via a further link 55, a slider 54 constrained to slide between pins 56-59 carried by member 22. When a notch 62 on the slider engages pin 58, a further notch 64 engages pin 56 under the action of a spring 60, thereby preventing further movement of the slider, locking the member 22 to the link 50, and releasing a hook part 68 of the slider from stop 66. Further rotation of the spindle then causes the member 22 and the closure member to swing about the spindle to the fully open position. In closing, the reverse procedure is obtained, the slider being unlocked by abutting stop 66 which moves it against the spring to free pin 56 from notch 64. The operating means may comprise a pivoted power cylinder 25. The threaded connection between members 22 and 40 may be replaced by a ball rotating between stops in a helical track (Figs. 4 and 5, not shown). In the alternative embodiment of Figs. 10, 11 and 13, the connection between the closure member 80 and carrier member 82 comprises a spring loaded toggle 102. In operation from the closed position of Fig. 10, rotation of the closure member is at first prevented by pins 116 thereon engaging in holes 117 in the valve end-plate. Limited movement of the carrier member relative to the closure member is permitted, however, by means of pins 110 on the latter engaging slots 112 in the former. Consequently the toggle moves from the position of Fig. 14 to that of Fig. 13, thereby lifting the closure member from the seat and releasing pins 116. Further rotation of the carrier member is then possible to swing the closure member to the open position. When closing, the closure member abuts a stop 114 which allows the carrier member to straighten the toggle against the action of a spring 108. The driving means for the operating spindle 87 may again comprise a power cylinder.

[Class 18.] In a box for gramophone needles and the like provided with actuating means for moving the needles into a delivery recess from which they are delivered by an ejector, the actuating means is combined with the needle holder which comprises spring-actuated members holding the needles upright so that when the actuating means is operated the holder is moved to carry the needles past the delivery recess into which one is forced. As shown, the delivery recess 5 is formed in the wall of a cylindrical jacket 3 mounted in the box 1 and the holder consists of a pair of arms 8, 12 pivotally mounted on the pin 7 and forced together to hold the needles 4 upright by a spring 13 on the pin 7. The arm 8 extends out through an opening 9 in the jacket 3 and with a handle 11 forms the actuating means by which the needles are moved past the recess 5 and into which one of the needles is forced to be ejected therefrom by a lug 24 projecting into the recess when the handle 11 is released and moved back in its opening 9 by the spring 13. The lug 24 is carried by a member 22 slidable on a rod 23 and connected with a spring- controlled lever 18 having a cam surface 20 bearing against the arm 8 ; means are provided to move the lug 24 out of the delivery recess as the member 22 descends when the arm 8 is actuated to move a needle into the recess. The ejected needle projects through an opening 26 in the box and the opening may be provided with friction means to prevent the needles being ejected too violently. A holder for used needles is formed by arm 14 pivotally mounted on the pin 7 and acted upon by the spring 13 and a stationary arm 15, the used needles being introduced between the arms through a recess 6 in the jacket 3.
