Patent GB-2075313-A (GB)
Title: Echo cancellers
IPC: H04L5/14
Filed: 1981-04-06
Abstract: A full-duplex, two-wire Nyquist sampled data communication system includes an adaptive echo canceller (24) at each terminal (e.g., 10'). The echo canceller generates a replica (zm) of the echo component of each sample (rM) of the incoming signal. The replica and the sample are subtractively combined to provide an echo compensated signal (SM). During intervals of simultaneous transmission and reception, i.e., double talk, the echo compensated signal may contain not only an uncancelled echo component but also a far-end data component. An adaptation error signal generator (80), operating in response to a stream of recovered data symbols (e.g., ân), estimates and removes the far-end data component from the echo compensated signal and, in response to the difference, generates an adaptation error signal ( gamma EM-D). This signal is applied as an error signal to the echo canceller. This allows the echo canceller to adapt its set of tap coefficients in response to the uncancelled echo component present in the echo compensated signal. Thus, stable and accurate echo cancellation results even during a double-talk interval. <IMAGE>

Title: High-speed common transmission lines for telecommunication or data processing systems
IPC: H04Q1/16
Filed: 1981-04-24
Abstract: A common transmission line or bus is provided for exchanging information at high-speed (above 10 MHz) and over considerable distances (up to 150 m) between circuit units connected to the bus. The bus comprises loop wires of balanced type through which the transmission occurs and which are twisted and joined together to form a flat cable B. The bus comprises one or more superimposed flat cables B inserted in a metal shield SC connected to earth. Stubs extending from the bus and connected to the various circuit units R by insulation-piercing connectors ON are very short and do not affect the physical continuity of the bus. The bus has a modular structure, i.e. it comprises lengths (usually one length per frame) which can be mutually connected in series with each other without substantially altering the characteristic feature of the bus. The bus is arranged as near possible to the reference earth in common with the power supplies of the various circuit units. <IMAGE>

Title: Potato processing apparatus
Inventor: WRIGHT RAYMOND GRENVILLE WHITE
IPC: B07B13/04
Filed: 1981-06-19
Abstract: A walking beam conveyor 28 feeds potatoes in a direction F to a cutting station where they are cut along planes 41 and 42 into four pieces. The conveyor 28 is pocketed and the pockets are configurated so that they cause each potato on the one hand to become oriented with its larger dimension generally at right-angles to the feeding direction F, and on the other hand to move to a central position transversely of the conveyor 28. Thus, each potato is in a predetermined position when it arrives at the cutting station, so that the four pieces into which it is cut are roughly of equal size.

Title: Dynamic energy dissipating pipe support with pneumatic damper
Inventor: SANTOS L A G D DR
IPC: F16L3/20
Filed: 1982-02-11
Abstract: An air damper comprises a rod 5 with flanges 1, which slides in a casing 2 with partitions, the flanges and the partitions cooperating to define intercommunicating chambers. The apparatus uses air as the damper fluid, thus eliminating leakage problems and expensive maintenance, normally associated with conventional energy dissipating oil dampers. The air damper can be used in conjunction with a linear or rotational spring and mass system, or a snubbing unit. Less costly maintenance and more effective reduction of stress levels in pipework, under dynamic conditions, can be expected using this method. The apparatus is particularly suitable for nuclear pipework applications. <IMAGE>

Title: Magazine for framed transparencies
IPC: G03B23/04
Filed: 1982-02-25
Abstract: A one-piece elongate magazine of plastics material for framed transparencies has two open sides and one closed side. The magazine is provided with flexible walls (12) which define compartments for the transparencies and which walls each taper inwardly towards a corner at which an L-shaped retaining element (26) is arranged. The retaining elements (26) prevent dropping-out of the transparencies from the compartments forwardly as well as upwardly. The compartment walls (12) each have an upper portion (22) and a lower portion (11) and are constructed to be of different thickness over their area. Together with the narrowed shape of the upper portion (22) of the compartment wall, a greater yieldability results for this upper portion than for the lower portion (11). The particular shaping of the walls also facilitates gripping of individual transparency frames and removal of the transparencies forwardly and upwardly from the magazine. <IMAGE>
