Patent GB-2257229-A (GB)
Title: Seal for service conduits
Inventor: GILBERT JOHN
IPC: F16L55/00
Filed: 1992-08-07
Abstract: The invention relates to seal means 14 which is removably mountable on a guide and which has a flange 13 and a flange 16 for connection with a pressure resistor (not shown) and a metal body 17 of cylindrical form connecting the flanges 13, 16. Secured between the flanges 13, 16 and spaced from the body 17 to form a space or manifold 18 there is an expansible member in the form of an elastic compression sleeve 19 which has reinforcements in the form of spaced fingers 20 of KELVAR (Registered Trademark) along the upper and lower edges (as viewed). The sleeve 19 lines a through bore 21 through which the cable 1 can be passed. In order to seal the volume round a cable 1 against liquid flow, the sleeve 19 is expanded into the bore 21 to embrace the cable 1 by passing fluid such as water under pressure into the manifold 18 through an inlet port 22. The sleeve 19 embraces the cable 1 firmly but gently so that it is not damaged and its communications carrying integrity is not disrupted. Meanwhile, the whole of the bore 12 is obturated by the sleeve 19. <IMAGE>

Patent GB-928551-A (GB)
IPC: C07C51/275
Abstract: 928,551. Terephthalic acid. MONTECATINI SOC. GENERALE PER L'INDUSTRIA MINERARTA E CHIMICA. Sept. 8, 1961 [Sept. 13, 1960], No. 32353/61. Class 2(3). Terephthalic acid is produced by a process wherein p-xylene is gradually introduced into nitric acid having a concentration of from 5% to 15% by weight, in an amount greater than that chemically equivalent to the pxylene at 150‹ to 200‹C. The nitric acid is preferably used in an excess of 50 to 100% of the theoretical value. On completion of reaction the terephthalic acid is preferably filtered and unreacted acid brought to its original concentration by adding further nitric acid having a high concentration, e.g. over 50%, and re-used to oxidise more, pxylene. In an example 10% nitric acid is heated to 180‹C. and introduced into an autoclave provided with a stirrer. P-xylene is then added to the nitric acid over a period of 45 minutes. The spent acid is brought to a concentration of about 10%- by adding 57% nitric acid and then further p-xylene is introduced. The reaction is assisted by using a catalyst of powdered .copper and ammonium metavanadate and carried out under a pressure of 40 atmospheres. Terephthalic acid containing only minor quantities of p-toluic acid, nitroterephthalic acid and p-aldehydobenzoic acid is produced.

Title: Wide area bridging path selection
Inventor: WARWICK TREVOR
IPC: H04L12/46
Filed: 1993-07-24
Abstract: In a method and apparatus for the interconnection of local area networks by transparent bridging, two networks LAN1, LAN2 are coupled by a bridge pair B1, B2 which include a plurality of alternative communication links L1, L2, L3 between them. Data frames are transmitted from network to network over one the links, the link being selected according to a particular function applied to the unique source address of the device D1 - D6 sending the data frame. The function is chosen to optimise the distribution of data frames over the different links by appropriate selection of the number and position of the source address bits used as input to the selection function. Transparency of the bridging operation is maintained, and there is no conflict with spanning tree protocols. <IMAGE>
Patent GB-2271006-A (GB)
Title: Communication between processes
Inventor: IWASAKI MASAAKI
IPC: G06F15/17
Filed: 1993-09-24
Abstract: In a computer network, transmission and reception buffers 103,104, 109 -112 of sender and receiver processes are prepared as resident areas in main storage. A receiver node 122 notifies, prior to initiation of a communication, a physical address of, and access right code of, a data reception area of the node to a sender node 120. In the sender node, the notified physical address and access right code are added to transmission data. In the receiver node, received data is checked for validity and written in a location of the main storage at the physical address. Double buffering 108, 110, 112 is employed to prevent overwriting of a data reception area already in use. The respective nodes achieve partial synchronization with adjacent nodes in a chain, thereby automatically establishing synchronization between all nodes. <IMAGE>

Title: Detecting a railway vehicle
Inventor: BARNARD ROBERT EDWARD BLAKE
IPC: B61L23/14
Filed: 1994-03-29
Abstract: To determine the presence, or absence, of a vehicle on a predetermined length of railway track, axle counting detectors 1, 3, 2 count the number of train wheels entering and leaving each of at least two adjacent sections X, Y, in turn, and control means 5 respond to the receipt of entry/leaving count data from the axle counting detectors to give an indication of the presence, or absence, of a vehicle on the track.

Title: Winding continuously-delivered strand
Inventor: SASAKI KOUJI
IPC: B65H67/052
Filed: 1994-06-28
Abstract: A continuously-delivered strand 1, e.g. an optical fibre or electric wire, when fully wound on a first spool, is moved to be wound on a second parallel spool by snagging on a pawl co-rotating with the second spool. To prevent the snagging and cutting of the strand creating excessive tension on the strand layers already wound on the first spool, the strand is pinched by rollers 44 between the spools. Rollers 44, driven and spring-biased together, are axially advanced so that the strand 1 runs between them. A strand accumulator may be located downstream of rollers 44. Strand tension may be sensed upstream of the rollers to control roller rotation speed. One roller may be bodily rotated about the other to give the strand an S-shaped path (Fig. 38, not shown). <IMAGE>
