Patent GB-2088683-A (GB)
Title: Soil cultivating implements
IPC: A01B33/12
Filed: 1981-12-02
Abstract: A soil cultivating implement comprises a row of power-driven rotary soil working members 3 and a shield plate 9 arranged adjacent to each end of the row, the plate being upwardly and downwardly adjustable in position relative to a corresponding carrier 11 to match the pre-selected working depth of the members 3. The shield plates 9 co-operates with the adjacent members 3 in crumbling and distributing soil and, in order to minimise the effect of a stone or other hard object becoming momentarily trapped between one of the plates 9 and an adjacent tine 4, the carrier 11 of each shield plate 9 is movable outwardly and upwardly along a guide slot 14 against the action of a restoring spring 17 in such a way that displacement of each shield plate 9 can take place without significant tilting. If the upper and outer ends of the guide slots 14 are reached by pivot pins 13 that are slidable therealong, said shield plates 9 and carriers 11 can turn further outwardly about the axes of the pivot pins 13. An alternative embodiment is described and illustrated in which the guide slots 14 are replaced by sleeve-formation slideways movable axially along oblique guide rods against the action of restoring springs. <IMAGE>

Title: Improvements in or relating to interference controllers and detectors for use therein
Inventor: COULTER ROBERT PAUL
IPC: H04B3/23
Filed: 1982-10-20
Abstract: An echo canceller with improved near-end speech detection consists of a transversal filter (12) which synthesizes from an input signal (x(k)) on a receive signal path (12) an estimate of an echo replica signal (@(k)). A combiner (20) subtracts the echo replica estimate signal from the actual return echo signal (y(k)) on transmit signal path (14) to generate a first echo cancelled signal e(k). The improved near-end speech detector (24) comprises a combiner (28) and a transversal filter (26) which operate to generate a second echo cancelled signal (ed(k)) which is employed by a near-end speech detector (22) which compares the echo cancelled signal to past and present values of the input signal x(k) to ascertain the presence of near-end speech and inhibit the echo canceller. <IMAGE>

Title: Coffins
Inventor: PAPENFUS SIMON FREDERICK
IPC: B29C44/14
Filed: 1982-12-08
Abstract: Low cost coffins have been made of cheap wood, cardboard, hard board, or other like materials, often in kit form. it has also been proposed to make coffin kits of sheet metal components and from integral skin polyurethane. These coffins result in undertakers assembly costs and often have costly connecting components. They often have limited preservative ability. The present invention provides a cheap, lightweight and easily transportable coffin of simple construction and with preservative characteristics similar to robust wooden coffins. This is made by forming a jacket (28) of suitably reinforced hard setting material, such as a glass fibre reinforced plastics, and moulding a lining (40) of expanded material, such as polyurethane foam, onto the inner surface of the lining. The coffin lid (14) can be similarly made. <IMAGE>
