Patent GB-2241195-A (GB)
Title: Manufacture of articles from flat sheet heat-shrinkable plastics
Inventor: WELLS PAUL THOMAS
IPC: B29C65/00
Filed: 1990-02-24
Abstract: This invention describes a method of producing articles from thin sheets of pre-oriented heat shrinkable plastics material that could not be manufactured by other techniques such as injection moulding. The process is particularly suitable for making parts for the covering of irregular shaped articles that need to be screened from dust or moisture or electrically insulated with a heat-shrink product. The method involves the cutting of developed shapes from the flat material and the selective welding along a straight or irregular line to form the shape of best fit to the component to be covered. This will ensure a good fit with even shrink when the cover is heated to the shrink temperature. The sheet may include an adhesive coating that is activated during the shrinking process. <IMAGE>

Title: Polarimetric optical sensor device
Inventor: SIMONELLI FRANCESCO
IPC: G08C23/06
Filed: 1990-10-17
Abstract: The value of a physical quantity is read at a distance from the region where it is detected by means of a polarimetric optical sensor device. The device uses a single optical fiber 2 wherein both a measuring optical signal and a reference optical signal (of two different wavelengths) are conveyed. In the optical sensor 1, the reference optical signal is reflected by a member 7 upstream of the optical sensing element 10. The measuring optical signal passes through the element 10 and is reflected back through the element 10 by a member 11. In this way the sensor 1 of the device located in the region in which the physical quantity is to be measured does not require the presence of any optical connector and a miniaturization of the sensor is achieved so to reduce consequently the alteration by the presence of the sensor caused to the physical quantity being measured thereby increasing the accuracy of the measurement. The device may measure temperature, pressure, or electric or magnetic fields. <IMAGE>

Patent GB-2264107-A (GB)
Title: A float rollover valve for a vehicle fuel tank
Inventor: BOWLES DAVID THOMAS
IPC: F16K17/36
Filed: 1992-01-22
Abstract: A float rollover valve 4 which vents vapour from a fuel tank when the fuel is below a predetermined level (Fig 1) but closes a vapour outlet orifice 2 when the fuel is above the predetermined level (Fig 2) also reacts to pressure build up within the tank to vent gas until the ambient pressure and the pressure within the tank are substantially equalised. This is achieved by using a weighted link 12 resting on a pressure sensitive member 14, eg a flexible wall of the tank, which moves downwardly when pressure builds up within the tank and so allows a flanged head 11 to act against detents 10 to draw a float 5 coupled to a plug 4 away from the gas vent orifice 2. This permits the fuel vapour and gas within the tank at a pressure P<3> to be vented through a tube 3 to the lower atmospheric pressure P<1>. In rollover conditions the orifice 2 is sealed by the plug 4 under the effect of a spring 9 and the gravitational effect on the float 5 (Figure 4). The float moves in a two part float chamber (6, 7, Figure 1) which has a reaction arm (8, Figure 1) against which the weighted link 12 bears in the rollover condition, the reaction arm passing through an aperture in the float 5. <IMAGE>

Title: Multicompartment electrodialyzer for desalting aqueous solutions
Inventor: MEDVEDEV IGOR N
IPC: B01D61/44
Filed: 1992-03-31
Abstract: The electrodialyzer comprises a plurality of parallel chambers formed alternately of an ion exchange membranes and cation exchange membranes 2, 3, 4 arranged in a non-linear flow path for the aqueous solution e.g. from inlet 12 via pipe 16 connecting the anode chamber 5 and desalting chamber 7 through opening 17 in membrane 4 into the cathode chamber 8 so that the solution passes successively across a surface of each of the membranes, the two end chambers housing an anode and a cathode connected to a source of electrical bias which causes ions to form and to migrate from the flow path into a concentration chamber 6 from which the concentrated fluid can be drawn off. The build up of sedimentary salts on the membranes which is a common problem of known electrodialyzers is reduced and less pipe branches are needed too. <IMAGE>

Patent GB-2268173-A (GB)
Title: Filter medium
Inventor: QUINN JENNIFER JOAN
IPC: C02F1/28
Filed: 1992-06-30
Abstract: The invention relates to a filter comprising a composite medium which can achieve, in sewage water to be treated, both solids removal and disinfection of the water being treated. This effect is particularly applicable in the tertiary treatment of sewage effluent requiring both "polishing" (solids/ammonia removal) and disinfection (bacteria removal) prior to discharge. Alternatively, a composite medium embodying the invention may be used as part of an advanced clean water treatment process where a filter comprising the medium would be situated downstream of a granular activated carbon filter, and/or possibly at the point of use. Such an application reduces the need for a residual chlorination system and operation in a sewage treatment works.

Title: Flexible roll-up door
Inventor: MANSLEY DAVID LESLIE
IPC: E06B9/80
Filed: 1992-10-07
Abstract: Two doors, each comprising a pair of spaced flexible panels 15 and 16 are connected at their free ends by a safe edge 17 and are wound onto or off associated drums 18 and 19 which are geared together. The edge 17 is powered between an open and closed position by a motor (33 Fig 3) which engages a cog (23) to cause rotation of a drum 25 to cause a carriage (14) to pull the edge. A wind bar 22 moves at half the speed of edge 17 via drum 24 and carriage (13). The drum 18 is connected to the same drive shaft as the drum (25) via a torsional spring (41) and may pivot relative to the drum (25) by an amount restricted by the ends of an arcuate slot (47 Fig 6) to compensate for the increase or decrease of the effective diameter of the drum 18 as the flexible door is being wound onto or off the drum 18. Under windy conditions this mechanism also prevents excessive bagging of the door and prevents the ballooned door being trapped between the free edge of the door as it approaches drum 18. <IMAGE>
