Patent GB-2279326-A (GB)
Title: Paving stone lifter
Inventor: WALSH PATRICK JOSEPH
IPC: B66F15/00
Filed: 1994-06-28
Abstract: A lifting device comprises a carriage 10 which supports a pair of pivotable arms 16, each of which has an L-shaped engagement portion 18 at its lower end. In use, an object 21 (such as a block) to be lifted is frictionally engaged on its side faces 20 by the engagement portions 18. The weight of the object 21 pulls the arms 16 downwardly and urges these to pivot, thereby urging the portions 18 into even closer engagement with the side faces 20. In this way, the weight of the object 21 itself provides the means whereby it is held securely between the arms 16. Preferably both arms are adjustable in size, suspended by chains 19 and have a remotely released retaining mechanism 22. <IMAGE>

Title: Improvements in and relating to the bending of elongated plastics sections
Inventor: CUNNINGHAM ALAN
IPC: B29C53/08
Filed: 1994-06-30
Abstract: Apparatus for use in bending pre-heated elongated plastics members 20 to a predetermined arcuate shape comprising a support table 22, a former 28 and a plurality of mounting means 26 to which said former 28 engages and wherein the position of each mounting means 26 is adjustable such that the former 28 adopts the desired arcuate shape. In a first aspect of the invention the former 28 co-operates with the mounting means 26 by sliding engagement (via locating pins 62 having cylindrical heads 66, 68 riding in T-shaped slots 60, 35 formed in former 28 and mounting means 26 respectively) and in a second aspect the former 28 is movable perpendicularly to the plane of the table 22. The invention finds particular application in the bending of uPVC members for windows and doors. <IMAGE>
Patent GB-2283516-A (GB)
Title: Retrievable well packer
Inventor: HENDRICKSON JAMES DAVID
IPC: E21B33/128
Filed: 1994-08-18
Abstract: A retrievable packer suitable for service under high temperature and pressure conditions provides improved sealing by a seal element prop surface (56) which is radially offset with respect to the seal element support surface (48) of the packer body mandrel (34). In the set condition, at least one seal element (30A) is supported on the elevated prop surface (56) and is subjected to a radial squeeze, even though the lowermost seal element (30C) may be subject to longitudinal separation. The split level seal element support arrangement provides an annular pocket into which the seal elements can be retracted upon release and retrieval of the packer, thereby providing clearance for unobstructed retrieval. Upon release of the packer, a retainer collar (68) is shifted away from a lower metal backup shoe, thereby providing an annular pocket into which the metal backup shoe is deflected, so that it does not obstruct the drift clearance as the packer is retrieved. Preloading of the seal element assembly is provided by a cover sleeve (50) which releases, and longitudinally moves along the body mandrel (34), when a predetermined amount of longitudinal seal compression has been achieved. The cover sleeve (50) carries, for longitudinal movement therewith, an upper metal backup shoe (162) positioned to be engaged and deformed by the upper end of the seal element assembly. <IMAGE>

Title: Padlock with lock unit retained by chamfered plate held in dovetail joint
Inventor: BAYES SYDNEY
IPC: E05B67/38
Filed: 1994-12-13
Abstract: A padlock includes a hardened steel retaining plate 38 with a chamfered peripheral edge which rests on an internal abutment shoulder 40 in a recess 20 and overlies a lock unit 24. The peripheral edge of the recess 20 is forged or deformed to create a lip 42 which securely holds the retaining plate against the shoulder 40, thus defining a dovetail joint. The padlock can be used conventionally or with a fitting 80 comprising a stud 84 with an enlarged head 86 attached to a plate 82, and a second plate 90 having a circular aperture 92 which can be passed over the stud 84. A groove 68, between the studs 58 and 60 of the fastening member 50 of the padlock, passes over the stud 84 when the lock is open. When locked, a curved area at the top of the groove 68 engages against the enlarged head 86 and prevents the lock from being removed. Hence the two plates 82, 90 are locked together. <IMAGE>

Title: Workpiece positioning apparatus
Inventor: HEAD MERVYN PAUL
IPC: B25H1/18
Filed: 1996-09-20
Abstract: A workpiece positioning apparatus comprises a turntable 12, gripping means, drive means 32 for turning the table (in the plane of the table) about a first axis and a tilt actuator 49 for tilting the table about a second axis perpendicular to the first axis. In use, as the orientation of the table changes from the horizontal (Fig 1) to a more inclined position (Fig 3) and thus the eccentric load exerted by the workpiece increases, the tilt actuator 49 exerts a greater moment/torque due to the increase in effective lever arm. Preferably the tilt actuator comprises a screw jack actuator 49, a mounting 48 and an extendable arm 50 pivotally coupled to a lever plate 54. The increasing torque of the tilt actuator is designed to enable the apparatus to handle workpieces of a substantial mass.

Inventor: PROCTOR RICHARD JOHN
IPC: H04Q3/00
Filed: 1996-09-24
Abstract: In an ATM telecommunications network an encryption key used for data transmitted between a source and a receiver may be updated. The data is sent initially using a first encryption key by a first virtual path, a connection being established by a second virtual path and a second encryption key sent by that connection from the source to the receiver. The data is later sent using the second key by the second virtual path. The first path is then disconnected.
