Title: Waste handling apparatus
Inventor: FINCH MAURICE
IPC: B07B13/16
Filed: 1987-07-03
Abstract: A waste handling system for solid, domestic or commercial waste materials, serving as a pre-screening plant for such materials prior to further treatment thereof and adapted to receive materials in both bagged and loose forms, comprising an input hopper (10), and an input conveyor (11) leading to the input end of a rotary screening drum (16). Product material passes through the drum to an outlet (19) whilst screened materials are conveyed away by a conveyor (20) to one or more further outlets (21). In its passage to the drum, the materials, some bagged, are subjected to a tearing and levelling action by a toothed device (14), which slits open the bags. The device (14) comprises an endless series of teeth (22) carried on chain-link plates (23) around a pair of chain wheels (24) at least one of which is motor-driven. The device is pivotable about an axis (26) and can swing through an arc (27) above the input conveyor (11).   <IMAGE>
Patent GB-2211355-A (GB)
Title: Magnetic workholders
Inventor: MANLEY DAVID JAMES
IPC: B25B11/00
Filed: 1987-10-16
Abstract: A switchable magnetic workpiece holder has in an upper, work support member 10 an array of ferro-magnetic pole pieces 17, and in a lower, relatively-slidable, ferro-magnetic magnet carrier 11 a corresponding array of flat magnets 19. The pole pieces are magnetically isolated from one another by non-magnetic separators 13 and the magnets 19 are likewise magnetically isolated at their peripheries from adjacent ferro-magnetic parts 22 of the magnet carrier by non- magnetic separators 21. When the separators in the magnet carrier are aligned with those of the workpiece support member, the workpiece is magnetically held in position. Each pole piece is provided at the upper, workpiece support surface with a central slot which serves to form for each pole piece two magnetically separated pole surfaces 14, 15. The magnets are preferably made of iron-neodymium-boron. Relative movement of the member 10 and the carrier 11 diverts magnetic flux away from the workpiece which may then be removed. <IMAGE>

Title: Fire resistant pipe seal
Inventor: DAVIES ERIC GORDON
IPC: F16L23/12
Filed: 1987-12-23
Abstract: A pipe seal, lined with a material similar to the lining of the pipework to which it is fitted is used to reduce or minimise the risk of the pipe seals formed by the liner extensions over the flange faces melting away or blowing out in the event of the pipe joint being overheated as in the event of a fire. The lips or rims on the seal encase the flared liners and are allowed to compressor collapse in the event of them being too wide. When collapsed, the resilience of the seal legs holds the rims against the adjacent flange surfaces.   <IMAGE>

Patent GB-2213201-A (GB)
Title: Air-cooled engine and driven machine assembly
Inventor: ISHII AKIRA
IPC: F02B63/06
Filed: 1988-12-02
Abstract: A casing 1 is partitioned into a machinery chamber, containing an engine 4 and a driven machine e.g. a generator 5 or compressor, and a fan chamber 3 containing a fan 6 which may be mounted on the generator shaft 8, driven from the engine or generator through a transmission, e.g. an endless or geared transmission, or driven by an electric motor. The fan 6 draws air through the machinery chamber, to cool the engine 4 and driven machine, into the fan chamber 3. The air expelled from the fan chamber 3 is divided between two outlets 53 and 54. Air from the fan outlet 54 returns to atmosphere through a passage (35, Fig 6) surrounding the engine exhaust silencer (34) so as to cool the exhaust gases and thereby reduce exhaust noise. Air from the other outlet 53 returns freely to atmosphere, thereby ensuring a sufficient cooling flow for the engine and driven machine. <IMAGE>

Patent GB-2221047-A (GB)
Title: A coupling load sensor
Inventor: CORNWELL MICHAEL IAN
IPC: B60D1/06
Filed: 1989-06-15
Abstract: A coupling load sensor formed as a trailer coupling has means for detecting if the vertical load applied to the coupling by the trailer exceeds a predetermined threshold. A coupling body (12) has a slidable pin (22) resiliently biased by a spring (28) and surmounted by a coupling ball (27). The spring (28) is compressed by the load applied by a trailer and the degree of compression of the spring (28) is indicative of the trailer load. This may be represented purely visibly at the coupling by a reference mark (29, 30, 31) referred against a movable index (23) on the pin (22), or may be indicated by means of microswitches (54, 55) engaged by an actuator (53) to cause illumination of warning lamps (59, 60, 61) in a dashboard panel (58). In an alternative (Fig 3), the load is detected by strain gauges mounted on the upper and lower surfaces of the drawer bar of a trailer. <IMAGE>

Patent GB-2237297-A (GB)
Title: Pitched roofing with brick cladding
Inventor: SMITH ANDREW JONATHON
IPC: E04B7/20
Filed: 1989-10-23
Abstract: A system of pitched roofing is 'environment friendly' in that it completely eliminates the use of timber, thus reducing the present trend to deforestation. The sub structure is formed from prestressed concrete interlocking panels (designated "Roofplank"), which themselves interlock onto precast concrete portal frames, with a precast concrete eaves unit which combines the function of eaves tie and surface water gutter. This provides a stable structure unit, all from standard components, which is virtually maintenance free. The structure is then infilled as shown with 2 courses of standard modular brickwork in waterproof mortar. <IMAGE>

Patent GB-2236699-A (GB)
Title: Component protection from contaminants
Inventor: GASPER JOHN E
IPC: B29C31/04
Filed: 1990-09-03
Abstract: During the manufacturing process for turbine blades and vanes, among other hollow articles, the hollow cavities can become contaminated. Removal of the contaminants is a tedious, time consuming process which commonly results in component rework or rejection. Introducing a polymeric foam filler into the hollow cavities, prior to manufacturing, prevents contamination; enhancing manufacturing, efficiency and component integrity. Filling is by gravity via a boot (60) or negative pressure infiltration. Subsequent removal is by solvent or heat. The blade or vane can be encapsulated using a mould or moulding paper. <IMAGE>
Patent GB-2247373-A (GB)
Title: Method for resolving ambiguity in the determination of antenna angle of view and Doppler frequency in synthetic aperture radar
Inventor: RUNGE HARTMUT
IPC: D21F1/02
Filed: 1991-08-16
Abstract: A method for resolving ambiguity in the determination of antenna angle of view and Doppler frequency in synthetic aperture radar (SAR) comprises evaluating the dependence of the Doppler frequency on the transmitting frequency so as to measure a skew of the two-dimensional Fourier power spectrum or the two-dimensional autocorrelation function of radar data. For this purpose the radar data are subjected to a range Fourier transformation and for the individual range frequencies in a following Doppler centroid estimator a Doppler centroid determination is carried out in the azimuth direction. By this method the pulse repetition frequency ambiguities may be eliminated without any demands having to be made on the data acquisition or a high image contrast; this method can therefore be applied to any region of the raw data matrix. Moreover, no azimuth compression is necessary. <IMAGE>

Inventor: BOIX JAEN JOSE
IPC: B31B3/46
Filed: 1992-06-30
Abstract: An extensible former, which is introduced into a matrix containing a pressed cardboard plate which after folding thereof forms a box consists of two rectangular plates 1, joined together by a bridge 3 or sheet, and two wings 6, 7 which are pivotally mounted about their horizontal top edges 8, 9 between the plates, pivoting of the wings being limited by round profiles 10, 12 located between the plates 1.
