Patent GB-934016-A (GB)
Title: Dye beck and method of dyeing
IPC: D06B3/26
Filed: 1962-01-23
Abstract: A dyeing machine includes a pressure tank for dye liquor and material to be dyed, the tank in use being partially filled with dye liquor, means for heating the liquor in the tank when <PICT:0934016/IV(a)/1> the latter is sealed without diluting the dye liquor, whereby the pressure in the tank is increased, and a duct which communicates with the interior of the tank at a level above the bottom thereof, and extends downwardly below said level and has an outlet portion which extends above said level and is open to atmosphere, the duct in operation containing liquid so that when the pressure in the tank exceeds atmospheric pressure, a column of liquid is supported in the outlet portion of the duct.  As shown dye beck or tank 10 is made of a lower semi-cylindrical portion 12 and an upper section 14 the latter having a pressure door 34.  The fabric material 63 is fed in an endless path and in rope form through the dye liquor by means of an ovate drive reel 64 and an idler 66 the fabric being supported in the dye on a false bottom 58.  The reel 64 is driven by shaft 68 which extends through one end wall of the tank and is driven by chain 72 and reduction gear box 76 from a motor 80.  Steam coils 92 are mounted in the tank 10 beneath the false bottom 58 and are fed from a steam generator 94 through inlet pipe 96 to heat the dye liquor.  To maintain the temperature at a predetermined value a temperature responsive probe 108 is provided and connected to a suitable controller 110 to control the steam flow from the generator 94.  The tank 10 is made pressure tight so that as the air above the dye liquor becomes heated the pressure is increased and will prevent the dye liquor from boiling when its temperature increases beyond 212 DEG F.  In order that the temperature and the pressure do not exceed a maximum predeter-mined value a U-shaped duct 120 is provided, having one end 122 communicating with the interior of the tank at 124 slightly above the level A of the dye liquor and the other end extending upwardly to a level C above the level B.  At C the duct is in communication with two discharge tubes which extend down-wardly beneath the tank and are open to atmos-phere.  The duct 120 is filled with a liquid (either water or the dye liquor) and as the pressure above the dye liquor increases above atmospheric pressure the pressure acting on the liquid at ,122 will force the liquid down in duct 120 and upwards towards the level C. When the gauge pressure within the tank reaches the predetermined maximum value the liquid within the duct will flow out through the discharge tubes.

Abstract: 414,081. Lifting dogs and like gripping-apparatus. SUTCLIFFE, E. R., Sandfield Hall, Lowton, Lancashire. Jan. 27, 1933, No. 2626. [Class 78 (iv).] Apparatus for lifting a stack of bricks &c. comprises a frame b, of inverted U-shape which spans the stack and two or more pairs of gripping levers d pivoted at opposite sides of the limbs of the frame, the levers being connected with the lifting gear and carrying at their lower ends transverse holders h with resilient means for engaging the lowest row of bricks. As shown, in end view in Fig. 2, the two levers of each pair are connected by toggle links i with a bolt j, and two such bolts j are connected to opposite ends of a bar k connected with the hoisting shackle n. When the device is lowered into position over a stack of bricks, it is supported on the stack by a plate t carried by threaded spindles s, s adjustable in the frame, with the holders h clear of the ground and the bar k resting upon the frame. The bar k may be locked in this position by pins on a bar o which may be moved longitudinally into the locking position by a hand-lever O<1>, in order that the device may be lifted without gripping. When the looking device is released, and the device is lifted by the shackle n, the bar k moves upwards in the frame until the holders h engage the load or the bar meets stops which limit its movement. The threaded rods s, s may be adjusted vertically to suit the height of the stack by a hand-wheel which operates two worm-wheels s<1> mounted on nuts in a casing r carried between the two frames b or opposite ends of the device, and housings are provided on this casing to receive the rods o. Each holder h is a channel bar in which a length or lengths h<2> of indiarubber is wedged by a bar of wood or similar material so as to protrude from the channel. The rubber is shaped at h<4> so that it may be reversed when worn, and so that it cannot be gripped between the bricks and the edges of the channel bar, and vertical slots h<3> are formed in the rubber to permit compression. The indiarubber may be replaced by helical springs. Specification 274,221, [Class 78 (iv)], is referred to.

[Class 104 (iii)] In a current-collector of the trolly or bow type, the truss rods are connected at one end to a sliding sleeve 8 on the trolly pole 6 against which the pole spring 7 abuts, and at the other end are pivoted to one arm of a bell-crank lever 13. The other arm of the lever is pivoted at 14 to an extension 15 of the rotatable sleeve 3 on which the pole socket 5 is pivoted, and its pivotal axis 16 is engaged by a cam 17 pivoted on the spindle 4 of the socket 5. If the trolly leaves the conductor, the pole 6 turns upwards on its pivot 4 until the socket 5 engages a stop 19 on the cam and turns the cam anticlockwise. This movement releases the lever pivot 16 from a locking catch 21 pivoted on the cam and pressed towards the pivot 16 by a spring 22. The pole spring 7 expands until its abutment 8 engages a fixed collar 9 on the pole. The pole then falls by gravity until its socket 5 engages a second stop 18 on the cam. A brake member 26 working in a socket 27 in the base 1 is carried by a spring plunger 23 and limits the movement of the pole when the cam engages the head 24 carried by the plunger.

Abstract: 450,106. Prepayment mechanism for meters. ENGLISH ELECTRIC CO., Ltd., TILSTONE, G., and DONELLY, J. F., 28, Kingsway, London. Jan. 30, 1935, Nos. 3050 and 12997. [Class 27] Switch latching mechanism for a prepaymentelectricity meter comprises a latch lever 18, Fig. 3, pivoted at 20, and biassed to a position for releasing a catch part 18b from a pin 16 on a switch operating member 13 (which is shown in its closed position), but normally held in latching position by a gapped disc 19 turning with the differentially operated member of the quantity mechanism, the disc 19 releasing the lever 18 to disengage the parts 16, 18b and permit opening of the switch when prepayment is exhausted. As the member 13 falls downwardly, when released, to open the switch, the pin 16 engages a hooked extension 18a of the lever 18 which is thereby turned to disengage the disc 19 so that the latter is free to rotate during the next prepayment. The pivot pin 20 engages a slot 18c of the lever 18 so as to permit upward movement of the lever during re-latching of the operating member 13 as the switch is closed. The releasing edge 19a of the disc 19 is undercut, and the lever 18 engages the disc normally at a point other than the releasing point 18d to prevent wear of the latter. Fig. 7 shows the mechanism applied to the prepayment mechanism of Specification 449,556, the latch lever 18 in this form being securely pivoted at 20, whilst the part engaging the pin 16 of the switch operating member 13 is in the form of a small spring-actuated latch element 17 pivoted to the lever 18, this latch element turning about its pivot as the member 13 is raised into the latched and switch closed position. As described in Specification 449,675 a small cleaning movement is given to the switch contacts each time a coin is inserted, even if the contacts are already closed owing to the amount previously prepared not having been exhausted. The mechanism is otherwise similar to that of Fig. 3.
