Abstract: The application describes a seal of the type comprising a housing and a J- or U-shaped hasp, the housing having first and second openings to receive the legs of the hasp. The first opening communicating with a third opening of the housing to form a channel for a first leg of the hasp. A locking mechanism is provided within the housing which is biased to resist withdrawal of the first leg of the hasp through the first opening. The hasp being lockable within the housing such that it can only be removed by cutting of the first leg of the hasp. The legs of the hasp are substantially rigid and are connected together by a resilient hinge such that in a first, relaxed position the legs adopt a position in which they are not parallel, the legs being moveable to a second, parallel position against the resilient force of the hinge for insertion into the housing.

Abstract: The application describes a closeable bag, pouch or container with an opening which can be closed by means of a lock unit which cooperates with a disposable locking member to close the bag, pouch or container. The opening has first and second opposing sides. The lock unit is on the first side of the opening and has first and second apertures. The second side has first and second apertures corresponding to those of the lock unit. The locking member has first and second protrusions for location in the apertures of the lock unit and the second side of the opening. The second side is clamped between the locking member and the lock unit. At least the second protrusion of the locking member has a configuration such that it locks into the second aperture of the lock unit. The locking member has a line of weakness running between the protrusions such that the first protrusion can be disengaged from the lock unit in a first step and the second protrusion can be disengaged from the lock unit in a second step.

Abstract: A retrofittable pressure gauge for a spray gun includes a pressure sensor, located in a pressure chamber, a power source and a display unit, all enclosed within a case, a passageway providing fluid communication between the pressure chamber and a pressurised interior space of the spray gun when the gauge is mounted on the spray gun and a mounting fixture configured for mounting the pressure gauge at a spreader valve or a trigger operated fluid valve of the spray gun.

Abstract: Security seals (1) are widely used to demonstrate the integrity of a closed container, truck, roll pallet, cage or box. Typically such security seals (21) are made from plastics material and have a strap (2) with a plug (5) at one end and a socket (4) at the other end. The socket includes a one-way lock so that when the security seal (1) is threaded through a locking point and the plug (5) inserted into the socket (4) the plus is locked irremovably into the socket. The only way that the security seal can subsequently be removed is by destroying it. Such a security seal (1) includes a recognizable sequence of indicia (20) extending along substantially the whole length of the strap portion (2) . The presence of the recognizable sequence of indicia (20) along the length of the strap (2) make it almost impossible to cut such a strap (2) and reconnect the cut ends without disrupting the sequence of indicia (20) so that it is immediately evident that the security seal (1) has been tampered with.

Abstract: The application describes breakable seal for a container, bag, pouch or reusable envelope which is closed by one part locating over a second part, the second part having an opening for receiving the head of the breakable seal which locks into the opening in such a manner that it cannot be removed without breaking, the seal in its inserted position locking the first part in place over the second part in a tamper evident fashion. The seal has an extended neck portion between the line of weakness and the main body part of the seal. Typically said one part is the fastener tab of the zipped opening of a reusable envelope and the second part is the enclosure or chamber of a lock unit mounted on the envelope, adjacent one end of the zipped opening.

Abstract: The present application describes a closable container having an opening which is closed by a flap of the container, the flap having an aperture which registers with a lock unit formed on a wall or side of the container, the lock unit having an opening for receiving the head of a breakable seal which locks into the opening in such a manner that it cannot be removed without breaking, the seal in its inserted position locking the flap over the lock unit in a tamper evident fashion, wherein the opening of the lock unit is arranged on one side of the lock unit, whereby in use the seal is inserted substantially parallel to the plane of the flap.

Abstract: A pressure-sensitive locking device comprises a housing (2,20) having an opening therein, and an insertable member (1,21) adapted to be inserted into the opening whereupon it can enter into locking engagement with a locking member (4,36) in the housing. The locking member (4,36) is cooperable with a pressure-sensitive mechanism (7,28) in the housing to effect disengagement between the locking member (4,36) and the insertable member (1,21) upon a reduction of pressure.

Abstract: A hinge for a vehicle lid includes a main biasing element operable to urge the hinge into an open position, and a mechanism for assisting the initial opening of the hinge from a closed position. The mechanism includes a rotary cam engagable with another portion of the hinge to provide assistance, and a further biasing element which acts on the cam to rotate it relative to the other portion of the hinge. A lifting aid includes a main biasing element for attachment between a lid and a body, which lid is pivotally moveable towards and away from the body. The main biasing element is operable to urge the lid from a closed position relative to the body to an open position. The lifting aid further has a cam attachable to the body for relative rotation thereto and a further biasing element for attachment between the body and the cam and operable to rotate the cam relative to the body and lid. The cam is operable to assist the initial opening of the lid.
