Title: Device for Moving a Ring Rail or Spindle Rail of a Textile Machine
IPC: D01H7/10
Filed: 1966-11-04
Abstract: 1,154,866. Programmed speed control of textile machines. ZINSER-TEXTILMASCHINEN G.m.b.H. Nov.4, 1966 [Nov. 5, 1965], No.49623/66. Headings G3N and G3R. [Also in Division D1] A speed control arrangement for the reciprocable ring rail of a textile machine comprises a rail drive arrangement controlled by a comparison between a selected desired speed and the actual speed of the rail whereby the actual speed of the rail is adjusted until it is the same as the selected desired speed. As shown, a ring rail 1 carries rings 3 along which travellers move during the winding of bobbins 5. The rail is reciprocated by a lever 11 actuated by a piston 7a in an hydraulic cylinder 7 supplied by a pump 17 from a tank 24 through a reversing valve 20 and an adjustable valve 22. The valve 22 is operated by an electric motor 34. The average speed of the rail 1 is determined by the actuation of switches 28, 29 during the upward travel of the rail. The switch 28 initiates a timer 30, the output of which is connected to a first input of a comparison device 32 having a second input from the switch 29. The output of the comparison device representative of the timer delay and time for the rail to travel between switches 28, 29 controls the motor 34 so as to tend to maintain constant the average speed of the rail. The time of operation of the timer 30 is set by a programme control device 70' sensing desired speed variations recorded on a programme carrier, or manually by a device 70. The distance between switches 28, 29 can be adjusted by a worm and nut device 6 responsive to a programme control device 8. In alternative speed determining and controlling arrangements (a) the comparison is effected by a timer driven potentiometric or Wheatstone bridge arrangement (b) a programmed worm drive positions a nut which is compared with the ring rail position by a differential switch and (c) a reversible friction drive from the ring rail drives in a fixed direction a tachogenerator the output of which is compared with a programmed speed signal to control the valve 22.

Filed: 1972-11-17
Abstract: 1376384 Reactors GULF OIL CORP 17 Nov 1972 [19 Nov 1971] 53273/72 Heading G6C A pressure-relief and containment system, e.g. for a nuclear reactor, comprises a containment enclosure 11 housing the reactor pressure vessel 12, a second enclosure 13, which is intended to be kept at an internal sub-atmospheric pressure, a duct 15 for conveying gas from the first to the second enclosure and a pressure-regulating fluid seal 16 maintaining separation between the interior spaces of the enclosures and capable of being breached to allow gas flow from the first to the second enclosure when pressure in the first enclosure reaches a predetermined level.  The enclosure 11, which can be the reactor building or a separate enclosure therein, is constructed to withstand pressures at or above the predetermined level for a period sufficient to permit dissipation of the excess pressure through seal 16 to the second enclosure 13. A vacuum breaker 43 prevents the pressure in enclosure 11 from falling below a predetermined level. In the seal 16, the duct 15 discharges via an outlet 61 having diffuser apertures 62. Stand pipes 67 provide, at their upper ends, a weir from which overflow is conducted to a chamber 58. Fluid from the latter can be reintroduced into an upper chamber 56 via pump 71. A chamber disposed above the weir and defined beneath a shield 65 is maintained at atmospheric pressure whereby, due to a subatmospheric pressure produced within the enclosure 13, the fluid in seal 16 normally has a level a. In the event of an accident which results in release of gas from reactor vessel 12, steam entrained in the gas passing through seal 16 condenses while the rise in pressure in the enclosure 13 is compensated by lowering of level a until such time as the normal pressure is reestablished. In the event of a low depressurization of the pressure vessel 12 such that the pressure in enclosure 11 -is insufficient to breach the fluid seal 16, a valve 53 may be opened to conduct gas to the seal 16 via a pipe 51. This facility enables the pressure in enclosure 11 to be reduced to, or held, slightly below atmospheric pressure. The second enclosure can be common to two reactors. (For Figures see next page.)
