Patent GB-2302293-A (GB)
Title: Method of coating granules
Inventor: NEWELL DOUGLAS ALBERT
IPC: B29B9/08
Filed: 1995-06-16
Abstract: Thermoplastic granules (such as polyethylene granules) are provided at a temperature below their softening temperature. Mineral grains, for example a mixture of sand and salt grains, are heated to a temperature greater than the softening temperature of the plastics material granules. The granules and the heated grains are tumbled together so that the granules become coated with the grains, and the coated granules are allowed to cool while the tumbling preferably continues. The hot coated granules can be at least partially cooled by the addition of an excess of cold grains. After cooling, the salt grains are dissolved away in water leaving the granules coated substantially solely with the sand grains. These particles are then particularly suitable for use as a fluidizable bed in waste water treatment plants.

Abstract: When lift car 12 rises from lower floor (18, Fig 1) to upper floor (16) through an aperture (20), the aperture infill (22) comprising board 62 rests upon the car top (24). There being no enclosure at either floor (16, 18) the car (12) must be made to stop instantly if there is an obstruction to the infill (22) in either direction or extra weight on the infill (22) when going up. The car 12 is fitted with two load-sensitive switchgear sets 26, one at each side. The infill (22) has two pegs 55 at its rear corners and two diagonal members 56 extending downwardly and rearwardly from its front comers, to depress the two spring-biased spools 28 of the switchgear sets 26. The pegs 55 operate the spools 28 directly, the diagonal members 56 operate the spools 28 indirectly through pivoted levers 46. Each spool 28 respectively operates an "up" switch (38, Figs 5-9) and a "down" switch 40 of its switchgear set 26 to stop the car 12 when the spool 28 is displaced up or down from its normal intermediate position. Preferably the levers 46 are two armed. Importantly, there is no electrical cable, trailing or otherwise, connected to the infill (22).

Title: Bearing assembly and method
Inventor: MCMEEKIN KENNETH MACLEOD
IPC: F16C33/04
Filed: 1997-11-04
Abstract: A dry bearing for a hinge pin comprises a bush 40 2  mounted in a housing 16, the bush being formed by rolling a strip of steel-backed, bearing material having a filled polymer infiltrated sintered bronze lining about a mandrel. The tubular form is burnished by pushing therethrough a burnishing tool to provide a uniform inside diameter. A minor part of the lining surface is, prior to passage of the burnishing tool and conveniently when still in strip form, compressed in part as depressions (44 2 ) arrayed over the surface. Such depressions permit burnishing with a less oversize tool thereby requiring less work in driving the tool and with less risk of shearing the lining components during burnishing.

Title: Database search engine
Inventor: YEOMANS ANDREW JAMES VICTOR
IPC: G06F17/30
Filed: 1997-11-06
Abstract: A search engine searches a database containing a plurality of data entries wherein one or more of the data entries comprise a link to one or more others of the data entries. The search engine receives, 300, an input search parameter from a user and compares the input search parameter with the plurality of data entries. In response to the comparison, the search engine identifies, 310, from the plurality of data entries a set of data entries matching the input search parameter and divides, 330, the set of matched data entries into sub-sets. Each sub-set comprises data entries having links to each other. The search engine determines, 360, for each data entry of each sub-set, a weighting in dependence on the number of links contained in each data entry to others of the data entries of the corresponding subset. This weighting arrangement addresses the problem that, typically, a large fraction of the WWW pages listed in response to a query originates at a single WWW site, and the volume of pages listed makes subsequent selection by a user difficult.

Title: Vehicle intruder alarm
Inventor: IACOVELLA ROCCO
IPC: B60R25/10
Filed: 1997-11-21
Abstract: A method of detecting intrusion into a vehicle is disclosed which incorporates an ultrasonic wave generator (1, 2) and a detection system that amplifies and rectifies (4, 5) the signal received by a detector (3). The system uses fuzzy logic to analyse various aspects of the detected signal, such as its frequency content (using filters 6), power and duration, so as to detect variations in this signal. The fuzzy logic output, whose functionality is implemented using a microprocessor (7), may then be used to trigger an alarm. The advantages are that by using fuzzy logic the number of false alarms may be reduced, and that by using a microprocessor to implement the fuzzy logic the conditions which trigger the alarm may be altered without changing the hardware.
