Abstract: A tufting machine configured to provide needles co-linearly along a tufting plane from opposing needle holders provided in a needle module. The needle holders may be selectively latched with latch pins connected to limbs extending from a yoke connected to the push rod of the tufting machine. The needle holders are biased in a dis-engaged position with compression springs which extend between caps on the needle holders and a guide plate which locates the needle holders laterally while spacing the opposed needle holders from one another.

Abstract: A yarn feed roller assembly for a tufting machine for producing multiple pile heights. The assembly comprises at least two rollers 5,6 driven at different speeds and a plurality of actuators 9, 14, 15 each arranged to bring an end of yarn selectively into driving engagement with either drive roller. The actuator may be switched between the drive rollers at a point during the needle stroke thereby varying the proportion of the stroke spent in contact with one or other drive roller, and hence varying the pile height.

Abstract: A tufting machine has a yarn feed roller assembly with a plurality of rotatable driver rollers driven at different speeds and a plurality of actuators in the form of a pivotable arm having in one embodiment a pair of yarn feed reels one of which is arranged to selectively press yarn into engagement with one of the drive rollers and the other arranged to selectively press yarn into engagement with another drive roller. Yarn is engaged by each actuator and a selected drive roller for a period of time determined by a pattern. The longer the actuator engages the high speed roller during the stroke of a tufting machine needle the greater will be the pile height of the tufts produced and alternatively the longer the actuator engages the lower speed roller during the needle stroke the lower will be the pile height. Pile height variations between a high pile and a low pile may be obtained by controlling the proportion of time during the stroke that the yarn engages with the high and low speed rollers.

Abstract: A frame for supporting a sign comprises three members which are interconnectable in such a way as to form a three-sided figure with one side forming a base and at least one of the other sides forming a mounting for the sign, each member being in the form of a hoop of tubular section.

Abstract: A method for blocking the bore of a pipe comprising moving an inflatable bag along the bore of the pipe from an access point in the pipe to a point where the bore is to be blocked, inflating the bag until it engages the internal wall of the pipe or main and causing the bag to maintain its inflated condition. Where an expandable foam is used.

Abstract: A method is provided for replacing an existing service pipe carrying fluid to an outlet within a property with a replacement service pipe. In the method the outlet is disconnected within the property from the existing service pipe in such a way that both during and after disconnection fluid is prevented from escaping into the property. A desired length of replacement service pipe is then fed into the existing service pipe in such a way that during and after the feeding step fluid is prevented from escaping into the property. The outlet is then connected to the outlet end of the replacement pipe 2 in such a way that during the connection fluid is prevented from escaping into the property and after the connection step fluid is allowed to pass to the outlet solely by way of the replacement pipe.
