The polyhydric alcohols may be glycerol and pentaerythritol, the polybasic acid may be phthalic anhydride and the drying oil which may be bodied or unbodied, selected from dehydrated castor, oiticica, tung, and blown linseed oils, and a blend of acid refined linseed oil with tung oil. Additional solvents, e.g. xylene, toluene or coal-tar naphtha and a catalyst, e.g. benzoyl peroxide may be added, and drying oil soluble, natural or synthetic resins, e.g. phenolic resins, may be included at any stage.  In examples styrene, with or without a -methyl styrene, cyclohexanone, phthalic anhydride and glycerol or pentaerythritol are heated with dehydrated castor or partially polymerized oiticica oil and benzoyl peroxide under a reflux fitted with a water-trap. Solutions in, for example, xylene, containing the usual metallic driers may be used as coating compositions. Specifications 573,809 and 580,912 are referred to.
Patent GB-860595-A (GB)
Title: Cycling valve for the control of fluid flow
IPC: F16K11/00
Filed: 1959-05-28
Abstract: 860,595. Valves. JAY, K. W. May 28, 1959 [May 29, 1958], No. 18217/59. Class 135. [Also in Group XXVI] A pair of outlets 36, 39 from a valve are connectable alternately with an inlet 31 by a closure member 83 that is reciprocable in a bore 15 under the control of an auxiliary valve member 62. The valve is suitable for controlling the intermittent injection of fuel into one or more of the combustion chambers of a gas turbine engine to ignite an after burner and when so used the outlet 39 is connected to the combustion chamber and the outlet 36 to a reservoir or to the pump that feeds the inlet 31. With the parts in the positions shown, fluid entering the valve housing passes through a passage 88 in the valve member to a conduit 53 leading to a bore 16 and thence through a turbine 73 and guide vanes 74 to a conduit 52 which communicates with the outlet 36. The rotation of the turbine causes, through a screwed connection 72, axial movement of a member 75 which has abutments 77a for engagement with a lever 68 pivoted at 63 on which the valve member 62 is mounted, the lever 68 being loaded by a spring 66 which moves past a dead-centre position so that the valve member 62 is snap-acting between its open and closed positions. Thus, after a predetermined movement of the member 75 to the right the valve member 62 is moved to engage a seating 59 to interrupt flow of fluid from the bore 16 through a passage 55 leading to the left-hand end of the valve member 83. Fluid can escape from the left-hand end of the valve member 83 through a restricted passage 85 so that the valve member is then moved to the left by the pressure at the inlet 31. The outlet 36 is then closed and fluid from the inlet 31 can flow through a conduit 51, through the turbine in the reverse direction, and through grooves 77 in the member 75 to a conduit 54 which will be in communication with the outlet 39 through a reduced part 89 of the valve member 83. Due to the reversed flow through the turbine the member 75 will be returned to the position in which it opens the valve member 62 to connect the left-hand end of the main valve member 83 again with the bore 16 to cause the main valve member to be returned to the right-hand position under the influence of a spring 21. Should the movement of the member 75 towards the left fail to open the valve member 62, the continued movement of the member 75 will ultimately cause a closure member 79 to engage a seat 82 to cut off the flow to the outlet 39. In a modification, the turbine 73 is replaced by a piston that reciprocates in the bore 16 and has a direct connection with the member 75, a restriction being placed in one of the conduits leading to one side of the piston to limit the rate of movement thereof.

Title: Improvements in bearded needle knitting machines
IPC: D04B9/04
Filed: 1920-07-03
Abstract: 146,449. Hemphill Co., (Assignees of Bosworth, G. P.). Sept. 20, 1915, [Convention date]. Circular machines.-In bearded-needle knitting- machines of the type in which yarn is fed direct to the needles without the interposition of measuring sinkers, the web-holders are so operated and controlled as to permit the yarn to be fed directly to the needles as in latch-needle machines and to prevent the yarn from being caught under the upper ribs 13 during the formation of heels and toes by reciprocation. The machine is provided with combined stitch-forming. and fashioning cams, substantially as described in Specification 146,450. The beards are pressed at a point d well above the upper ribs 13. The webholder cams which encircle the needles comprise a portion a<4> for placing the web-holders in an advanced or fabric-holding position, and a portion a which places the web-holders in an intermediate position with the forward ends of their upper ribs 13 in line with the needle stems as shown in Fig. 11. V-shaped notches b permit the end web-holders in heel and toe work to yield and recede from their intermediate positions when the loops are drawn down into fabric. The web-holders when in the intermediate position allow the yarn to take a straight course to the needles, as in latchneedle practice, without resting on the tops of the web-holders. In reversing for heels and toes, the encounter with the stem of the first idle needle z, Fig. 3, lifts the yarn up over the upper rib of the adjoining web-holder. This prevents the web-holders from trapping the yarn as they advance the loop-holding position under the influence of the cam a<4>.

Title: Fluidic operated thread tensioning devices
Inventor: COOPER BERNARD JOHN
IPC: B65H59/24
Filed: 1967-04-21
Abstract: 1,209,315. Tensioning flexible elements. ENGLISH ELECTRIC CO. Ltd. 18 April, 1968 [21 April, 1967], No. 18591/67. Heading B8B. [Also in Division D1] A device for tensioning elongate flexible material e.g. thread, wire rope or cable comprises fluid pressure operated variable tensioning means and feedback means responsive to changes in the tension of the material leaving the tension device to adjust the tensioning means so as to tend to cancel the changes. As shown thread 10  is tensioned by being deflected between stationary members 12 and a member 13 mounted on bellows 14. The yarn leaving the device passes through a loop 17 mounted on a spring 18 so that when the output tension of the yarn increases the spring is pulled away from a nozzle 19. Nozzle 19 is fed with pressurized fluid e.g. air and the position of spring 18 determines the pressure within the nozzle. The interior of the nozzle is connected to the bellows 14 and the arrangement is such that tension changes in the outgoing yarn tend to be erradicated. The mean tension is set by regulating the pressure of the fluid source or by varying a throttle 15. In an alternative form the pressure changes in tube 16 may actuate a single or multi-phase fluidic amplifier. In other forms a thread passes about the central post of a double disc tensioner, the pressure of the discs being regulated by bellows or a flexible bag. In Fig. 3, not shown, cable, e.g. pre-stressing cable is passed about a drum capstan (31). The tension in the outgoing cable is sensed by a feeler attached to a movable diaphragm (36) and the pressure within a nozzle (19) varied accordingly. These pressure variations operate a fluidic amplifier which causes a brake to be applied to or released from a disc mounted on the capstan shaft.
