Patent GB-2137246-A (GB)
Title: Drying corrugated board
Inventor: HARTLE MALCOLM JAMES
IPC: B31F1/28
Filed: 1984-03-14
Abstract: A method of drying moist corrugated board 6 comprises heating the laterally outer regions 6A of the moist board to a greater extent than the central region 6B during passage of the moist board through drying apparatus to reduce the moisture content of regions 6A to less than that of region 6B, such that, on cooling of the board 6, atmospheric moisture is taken up to produce a board with a substantially uniform moisture profile across its width. This results in a board which is more resistant to warping across its width. Apparatus for carrying out this method may comprise a plenum chamber 5 sub-divided to form laterally outer chambers 9, 10 and a central chamber 11 therebetween. Each chamber is fed with pressurised air. Chambers 9 and 10 may be raised to higher pressure than chamber 11 thereby resulting in increased pressing of regions 6A against steam chests below belt 3 as compared to region 6B, thus producing the differential heating. <IMAGE>

Patent GB-2202713-A (GB)
Title: Distributed access transmission system
Inventor: TEACHER VICTOR
IPC: H04L12/437
Filed: 1987-03-25
Abstract: A distributed access transmission system, also known as a local area network, uses two rings (MAIN, AUX) connecting the Central Office Equipment and the remote cabinets (N, N-1, N-2,...), with signal transmission in opposite directions over both rings. During normal operation, signal transmission occurs over both rings at the same time, with one or more time slots in a TDM bit stream allocated to each cabinet. If at a cabinet the received bit stream on one ring disappears the cabinet uses the other ring and sends out special code works at its time slot(s) to "tell" the central office equipment that a fault has occurred, and where. <IMAGE>

Title: Nuclear fuel pin fabrication
Inventor: DUROW KENNETH MATTHEW
IPC: G21C21/02
Filed: 1987-08-05
Abstract: A fuel pellet stack is fed into a fuel pin by a linear vibrator (72, 74, 76, 78) arrangement which imparts both vertical and horizontal components to structure (10) supporting the pin (84) and the pellet stack (82) and the phase relation between the vertical and horizontal components is adjustable to reverse the motion of the pellet stack in the event of a jam condition arising in the pellet guide 26. An I.R. camera 86 may detect when a jam has occurred and automatically reverse the pellet flow to clear the guide 26, after which forward flow may be restarted automatically. Alternatively forward flow may be inhibited if a counter connected to camera 86 indicates that not all the pellets have exited from the guide. Various guides 26 are described (figures 2 to 6) having a cross-section larger than that of the pellet to allow dust to accumulate without blocking the guide. <IMAGE>

Patent GB-2201016-A (GB)
Title: Memories and the testing thereof
Inventor: ASH KEVIN JOHN
IPC: G11C29/00
Filed: 1987-08-17
Abstract: A memory may contain a large number of bytes of data perhaps as many as 256 megabytes in a typical large memory structure. An error correcting code algorithm may be used to identify failing memory modules in a memory system. In a particular embodiment, a number of spares may be provided on each memory card allowing a predetermined number of defective array modules to be replaced in a storage word. With double bit correction provided by the error correcting code logic, a number of bits can be corrected on a card or a larger number of bits can be corrected on a card pair, where the larger number of bits is somewhat less than double the number of bits which can be corrected on a single card. The address test in accordance with the present invention then produces a pattern that will create a difference greater than that larger number of bits between the data stored in a storage location under test and any address that could be accessed by an address line failure. The method according to the present invention predicts the effect of an address line failure external to the array modules and internal to a card pair and then tests to see if a failure has occurred. The address test does not declare an address failure until a predetermined number of bit failures on a card is found. The test is valid for single and multiple address line failures. Since only one address bit is changed for each path through the test other failing address lines will not be detected until the path with those failing address bits are tested. Thus, even with multiple address line failure the two addresses that are stored to and fetched from are the only one address bit apart.
