Abstract: Randomized testing can be used to explore a set of possible transactions, schemas, and system states, including partionings, which can exist in a distributed database. The tests can be complementary to other system failure, performance, and version compatibility tests. Randomly generated transactions can be computed or evaluated at a transactor and compared to results derived from a transactor emulator.

Abstract: A carrier bag comprising a body having a closed base, closed sides and an open mouth opposite the base, handles extending from the open mouth away from the base, an attachment means extending from or separably connected to the handles and arranged separably to connect the handles together and two mounting member receiving formations, one on each side of the bag, arranged respectively to receive a mounting member of a mounting arrangement. A carrier bag comprising a body having a closed base, closed sides and an open mouth opposite the base, handles extending from the open mouth away from the base, an attachment means extending from or separably connected to the handles and arranged separably to connect the handles together, the attachment means comprising a loop of flexible material extending through apertures in the handles.

Abstract: A bag stack assembly (10) comprises a stack of bags (12). Each bag in the stack comprises front and back walls with closed sides, a closed base end, an open mouth end opposite the base end and a pair of handles extending from the open mouth end. The handles are connected together by means of an attachment bar block of material spaced from the open mouth end. The stack is folded about a fold line F extending across the bag. A jacket (14) retains the stack in the folded condition. The bar block is retained in a separate retainer (16) which is secured to the stack by cooperation between a retainer formation (28, 30) and the bar block. The folded stack protrudes from the retainer to allow removal of the bag from the stack.

Abstract: In a stack of vest-style carrier bags S, each bag comprises a front layer and a rear layer of flexible plastics material joined at the base and sides and defining an open mouth end. Handles extend from the open mouth end. A tab extends from each ply of material between the handles. An attachment block is provided between the handles and the handles are separably attached to the block by perforated lines of weakening. Front and rear tabs are separably attached to the attachment block. The rear tab of one bag is also separably attached to the front tab of the next bag in the stack so as to effect pulling of the front tab of the next bag from the stack. A container C is also provided for the stack with an opening 0 for allowing the bag to be removed and the subsequent front tab to protrude therethrough.

Abstract: In a stack of vest-style carrier bags S, each bag (10) comprises a front layer and a rear layer of flexible plastics material joined at the base (14) and sides (16, 18) and defining an open mouth end (20). Handles (22, 24) extend from the open mouth end. A tab (32a, b) extends from each ply of material between the handles. An attachment block (26) is provided between the handles (22, 24) and the handles are separably attached to the block by perforated lines of weakening. Front and rear tabs (32a) are separably attached to the attachment block. The rear tab (32b) of one bag is also separably attached to the front tab of the next bag in the stack so as to effect pulling of the front tab of the next bag from the stack. A container C is also provided for the stack with an opening O for allowing the bag to be removed and the subsequent front tab to protrude therethrough.

Abstract: A bag dispenser having a sling for supporting a roll of pre-formed bags.

Abstract: A tag (10) for supporting part of a bag on a bag dispensing apparatus, the tag comprising a body (12) having a dispensing apparatus attachment formation (16) at one end to allow attachment of the tag to dispensing apparatus and a bag attachment formation (28) at the other end to allow attachment of a tag to part of a bag. A bag comprising a body (52) having a closed base and closed side walls, handle members (56, 58) and an open mouth end (54), the bag further comprising two apertures adjacent the mouth end of the bag between the handle members and a weakened portion of bag material between the apertures.

Abstract: A stack (24) of vest-style bags (10), each bag comprises a front layer and a rear layer of flexible sheet material. The layers define a bag body having a closed base end (12), closed sides (14, 16) and an open mouth end (18) opposite the base end (12). The front and rear layers each define a tab (42) extending between handles (20, 22) of the bag. Each handle part defines an aperture (30, 32) to receive a pin of a dispenser. A further aperture (36) is provided to receive a hook pin of the dispenser adjacent the mouth of the bag.
