Access flooring of the kind which includes floor panels carried in spaced relationship above a floor substrate by a support mechanism, having a single fastening member which acts to clamp adjacent parts of a plurality of the floor panels to a single element of said support mechanism.

The present invention relates to a method, system and device for providing access from a terminal device (1) to a second access network (8). To achieve this an access network device (3) belonging to an first access network (12) stores a second access network information comprising information of second access network(s) (8) accessible from the first access network (12). Communication means between the terminal device and and the first access network are established and the second access network ...

A plurality of portable tokens are issued e.g. for authenticating instructions within an electronic banking network. Each token requires entry of a respective password in order to operate and becomes locked if a number of incorrect password entries are made. Each token also stores a respective cryptographic key and a random number generator. In order to unlock a locked token it outputs a random number and also encrypts that number under its respective key but does not output the result of the en...

An arterial access port which is grafted directly into the vascular system. The graft consists of a stem portion having at least one side branch extending from the stem for connection to an infusion port. The infusion port is in turn connected to a catheter or other similar device permitting the introduction of medication into the vascular system. The stem may take the form of a tubular section or an open surface for grafting into a side wall of a vascular channel. In use, medication or other ma...

An access device for providing access between a substrate surface and an elevated surface. The access device comprises a ladder having first and second ends, the ladder including first and second side members connected by a plurality of cross members extending between the ends of the ladder. The ladder is pivotally connected to a rotary axle extending horizontally from the support surface so that the ladder may be moved between a substantially downwardly outwardly disposed boarding position and ...

An access device (1) for providing access between a lower level and an upper level. The device (1) includes a platform member (2), a ladder member (3) and a rotating actuator (4). The platform (2) and the ladder (3) are movable between an access position (FIG. 1) wherein the ladder (3) is positioned downwardly and the platform (2) is horizontal, and, a storage position (FIG. 3), in which the ladder (3) is positioned upwards and the platform (2) is vertical. In a first step, the actuator (4) rota...

A circular duct is mounted on the circumferential, bared surface of a buried, coated pipeline so that the duct and pipe surface combine to define a sealed, circumferential chamber. A vertical conduit, defining in and out ports, extends upward from the duct through the dirt fill over the line. The ports provide communication between the ground surface and the duct chamber. A steel tape, having an ultrasonic probe mounted thereon, can be threaded through the assembly to bring the probe into contac...

An enclosed structure having an opening for access thereto with an acesss door, which can close the opening, mounted movably to the structure, and a latch mechanism for securing the door in closed position over the opening in the structure. The latch mechanism comprises a locking bolt pivotally mounted to a supporting bracket on the structure to be swung into and out of engagement with a pair of mating troughs in the edge of the door and opening. A pivot shaft extends laterally from the side of ...

A system is shown wherein, provided with an appropriate file organization, a data file can be read from a disk master file, given the file name, by performing one seek and one read operation. The system employs hash coding to compress a data file name to a disk file address. The disk file is positioned into fixed length blocks where each hashed file address points to a block, the block being as large as one cylinder or as small as one sector. Each block is organized such that it includes a direc...

A supporting frame for an access panel covering bath or shower fittings includes horizontal bars which are fixed directly to wall studs. Vertical bars are mounted for lateral adjustment on the horizontal bars to accommodate various center distances found in plumbing fittings. The access panel proper attaches to the frame in such a manner that it may be adjusted into flush relationship with tiled or painted walls of varying thicknesses.
