Abstract: An in-fill panel arrangement is designed for post and beam furniture systems of the type having overhead beams supported on vertical posts. Each of the beams has a lowermost face with a horizontal slot extending therealong, and each of the posts includes outwardly extending flanges having an end face with a slot extending vertically therealong. Beam-to-post connectors are attached to the opposite ends of the beams, and are detachably retained in the slots in the posts to mount the beams on the posts. Rigid in-fill panels are shaped to be positioned directly below the beams and above the floor to partition the space into individual work areas. Panel mounting brackets are detachably retained in the slots in the posts and the beams, and are connected with the in-fill panels.

Abstract: A post and beam furniture system includes a plurality of overhead beams, and a plurality of vertical posts having at least one outwardly extending flange with a single slot extending vertically along the end face of the flange. Beam-to-post connectors are attached to the opposite ends of the beams, and are detachably retained in the slots in the posts for mounting the beams on the upper ends of the posts. The furniture system may also include X-shaped posts and Y-shaped posts with slots which create an integrated mounting arrangement for detachably interconnecting the posts and beams in alternative configurations, and mounting accessories at a variety of different locations.

Abstract: An external utilities manager is designed for post and beam furniture systems of the type having overhead beams supported on vertical posts. The posts include outwardly protruding flanges which extend along the length of the posts. The external utilities manager includes a vertical raceway having a hollow interior configured to route utilities therealong, and an enclosed exterior disposed between the flanges of an associated post, and extending therealong to an open upper end. A horizontal raceway is positioned adjacent to and extends along the side face of an associated beam, and includes an interior configured to route utilities therealong. One end of the horizontal raceway is positioned adjacent to and communicates with the upper end of the vertical raceway to route utilities throughout the furniture system.

Abstract: A rolling boot for sealing a universal joint, having a first collar with a larger diameter to be secured to the outer joint part of the universal joint and having a second collar with a smaller diameter to be secured to a shaft at the inner joint part of the universal joint, and having a semi-toroidal boot wall connecting the collars, wherein the rolling boot is an injection-moulded or blow-moulded product, the rolling boot consists of a thermo-plastic elastomer and the elastomer is irreversibly cross-linked up to a degree ranging between 15 and 85%.

Abstract: In a procedure for the provision of access authorization for an engine-driven vehicle, if there is an operator request for the provision of access authorization to an engine-driven vehicle, a bidirectional signal transmission using encoded transmission signals and an electronic key will be effected. From transmission units located on or in the vehicle, vehicle signals will be transmitted to the electronic key, and, from the electronic key, key signals will be returned as echo signals to the respective transmission units. The time difference between the vehicle signal and the key signals will be determined and evaluated. The position of the electronic key in relation to the vehicle will be determined by means of successive bidirectional signal transmissions between at least two transmission units and the electronic key as well as by evaluating the time differences; having determined the actual key position, a decision on access authorization to the vehicle will be made.

Abstract: A device for monitoring balanced two-wire bus lines and two-wire but interfaces has first, second and third comparison circuits for comparing the wire potentials with one another and with a fixed reference voltage, and two shift registers or counters as well as at least one pulse generator for deriving reset pulses from each change in sign of the potential comparison of the two bus conductors with one another. The shift registers or counters are respectively reset by the reset pulses. Result signals produced from the comparison of the bus potentials with a fixed reference voltage can be fed to the shift registers or counters for the purpose of shifting or incrementing said registers or counters respectively. The register length or number of counter stages can be selected as a function of a desired bit error tolerance depth. The device can be extended by a self-resetting system after temporary bus disturbances.

Abstract: An electrically heated composite glass sheet including heating element wires deposited and fixed in place on the thermoplastic film connecting the individual glass sheets together so as to extend from the one film edge as far as the opposite film edge. The heating wires are connected in parallel with buses, which are arranged at a predetermined distance from the edge of the film. Directly adjacent to the buses, the sections of the wires which are arranged between the buses and the edge of the film are severed by moving two electrodes, which are connected with a power supply, into contact with the wires. The electric current heats the wires between the electrodes to their fusion temperature and thereby severs the wires.

Abstract: A biaxially stretched polypropylene monofilm, wherein the surfaces of the two sides of the polypropylene monofilm have different roughnesses R.sub.Z, is employed as an insulation film for the production of capacitors. The smoother of the two surfaces of the polypropylene monofilm is substantially free from fibrils and pits, so that no flaws occur in a metal layer applied on metallization of this surface.
