Patent EP-0527006-A2 (EP)
Inventor: GRIMES GARY JOE
IPC: H04Q3/52
Filed: 1992-07-23
Abstract: An optical switching unit requiring no optical-to-electrical conversions on optical data paths being switched through the optical switching unit. The optical switching unit (100) receives optical data information from one terminal (101,102) and switches it to another terminal. The optical switching unit frame synchronizes the data transmission timing of the terminals in accordance with the data transmission timing of the optical switching unit. This frame synchronization eliminates the need to provide data buffering and frame synchronization in the optical switching unit. The optical switching unit comprises an optical network (115), system clock (114) optical input interfaces (103,104) for receiving information from terminals, and optical output interfaces ( 107- 110) for transmitting information to terminals. The system clock determines the timing of each terminal using information transmitted to an optical input interface by the terminal. If the timing of a terminal does not match that of the system clock, the system clock blocks the transfer of data information by the optical input interface to the optical network and transmits timing information to the terminal via an optical output interface. If the timing matches, the system clock signals the optical input interface to communicate the data information to the optical network which switches the data information to optical output interfaces for transmission to terminals.

Abstract: The diffusion bonding of aluminium and aluminium alloys presents problems because , when left exposed to the atmosphere even for a short time, they acquire an extremely tenacious surface oxide layer that inhibits or prevents satisfactory diffusion bonding. Unlike titanium, this oxide layer is not absorbed at diffusion bonding temperatures. The present invention comprises a method of reducing oxidation of a surface of aluminium or aluminium alloy (10) by causing a nitride film to form on the surface. This film is believed to prevent oxidation of the aluminium or aluminium alloy, but to be absorbable into it at diffusion bonding temperatures. The nitride film is applied to the piece of aluminium or aluminium alloy (10) in a vacuum chamber (4) by sputtering with nitrogen ions, or by heating the piece (10) in a nitrogen gas atmosphere.

Abstract: A shaped, water-expandable water-sealing article (12) used for sealing an area between a first section (32) of at least partially cured concrete and a second, adjacent section (34) of substantially uncured concrete to form a plurality of water-sealed concrete sections. The clay water sealing article (12) is in the shape of quadrilateral, preferably a trapezoid, and is disposed to bridge an area between the two sections of concrete. Upon hydration of the clay contained within the shaped water sealing article, expansion of the clay creates expansion forces extending from a corner of the article that is surrounded by the uncured concrete, wherein the corner has an included angle greater than 90°, preferably at least 100°. The expansion force developed by the expansion of the shaped water sealing article are absorbed by a substantially increased area of the uncured concrete as compared to expansion forces resulting from a clay-based water seal having a 90° included angle at the corner (s) surrounded by the uncured concrete.

A terminal metal fixture 1 is inserted into the housing 5 through an opening formed in a rear wall of the housing in an axial direction of a bulb holding chamber 6. Then, the retainer 16 which is temporarily coupled to the chamber 7 is pushed into the connector chamber which receiving coupling pieces 3 of the fixtures 1 in holding apertures 17 in the retainer 17. When the retainer 16 reaches an inner section in the chamber 7, a lock projection 18 on the retainer engages with a lock face 14 in a longitudinal slot 12 formed in the rear wall of the housing 5, thereby bringing the retainer into a regular coupling position. Proximal ends of the coupling pieces 3, which is arranged perpendicularly to an inserting direction of the fixtures 1, are fitted in the holding apertures 17 in the retainer 16 which is secured in the housing 5. The retainer 16 is provided on its inner face of a side plate 28 with a guide slant face 281 a lower end of which is contiguous to rear end edges of the apertures 17. The apertures 17 are provided on their front, right and left end edges with guide slant faces 26. After the fixtures 1 are inserted into the housing 5 from its rear side, the retainer is pushed into the connector chamber 7 through the inlet port of the chamber 7. If the fixtures 1 are shifted, the fixtures 1 are corrected in position while the distal ends of the coupling pieces 3 contact with the guide slant faces 281 or 26 to insert them into the apertures 17. The retainer 16 is secured in the housing 5 when it reaches the inner section of the chamber 7.

A control means receives, for each cell, a channel identifier and a path identifier from which a first signal is generated indicative of a maximum delay value which is applied to the buffer store and used to schedule the particular cell for transmission, on a calendar controlling a sustainable cell rate. The control means generates a second signal indicative of a minimum delay value which is applied to the buffer means and, in conjunction with said first signal is used to schedule the particular cell for transmission, on a calendar controlling the peak cell rate. The apparatus can also handle routing information, where a group of channel connections define a Route which share a peak cell rate for the Route and are scheduled on the peak cell rate calendar.
