Patent GB-2196129-A (GB)
Title: Capacitive moisture sensor
Inventor: HOWARTH WALTER JAMES
IPC: G01N27/22
Filed: 1987-10-09
Abstract: The moisture content of a substance (1) on a moving belt (2) is measured as a function of dielectric constant. Two pairs of electrodes (4), (5) are positioned adjacent the belt, an inner pair of electrodes (4) and an outer pair (5), an A.C. potential is applied to the electrodes, the flux from the outer pair (5) passing through the substance (1) at a greater distance than the flux from the inner pair (4), and the current flowing between the electrodes of each pair is measured. Guard electrodes (6) surrounding the pairs of electrodes may be provided and the pairs of electrodes are sequentially switched to the guard electrodes so that the current flowing between the electrodes can be sequentially measured by passing a signal representative of the current through a synchronous detector whose output is divided into two D.C. levels by two sample and hold circuits, one representing the sum of the capacitance seen by the inner and outer pairs of electrodes and the other by the inner pair of electrodes. In further embodiments one of each of the inner and outer pair of electrodes may be a common ground electrode. <IMAGE>

Title: A method and apparatus for moulding a bend curvature into the tubular sealing part of a vehicle door seal
Inventor: KUEHNEN DIETER
IPC: B29C70/74
Filed: 1989-11-10
Abstract: For producing a bend or corner in a sealing strip 16, to match the shape of a bend or corner in its mounting flange, a portion of the sealing part 26 is removed between parts 26A and 26B, so as to produce a correspondingly shaped cut-out. The sealing strip is then placed within a mould cavity 54 which is curved to match the required configuration for the bend or corner and has an internal surface matching the external surface of the sealing part 26. A metal core 60, having a cross-sectional size matching that of the hollow interior of the sealing part 26, is placed in position within the cut-out by a swinging arm 58. Moulding then takes place whereafter arm 58 is swung outwards so as to withdraw core 60 (portion 26B has to be partially flattened to facilitate this). A small part D of the cut-out, which is blocked by, arm 58 during the moulding process, is left open. This is then closed off by a further injection moulding operation using a short core matching the cross-sectional shape of the core 60. This short core has a narrowed neck by means of which it can be pulled out of the sealing part 26B through a small hole in the sealing part which is thereafter closed by a grommet.

Title: Sterilising apparatus
Inventor: ABBOTT JAMES BERNARD
IPC: B65B55/04
Filed: 1991-01-21
Abstract: A station for sterilising containers, such as beakers on a sterile food packaging line has a chamber with permeable walls, e.g. a sintered stainless steel tube 6, which is surrounded by an outer tube 7 which has a plurality of outlets 10. A source of hydrogen peroxide 5 (H2O2) 1 is vaporised by heated air 4 and passed into the inner tube 6, from where it permeates to the outer tube 7 and via the outlets 10 to respective containers 18, to sterilise the containers. The combination of the inner permeable tube and outer tube serves to evenly distribute the H2O2 vapour to evenly sterilise a row of beakers, indexed through the station. In an embodiment, hydrogen peroxide is vaporised by heated air within a second permeable tube (24, Figure 5) which is surrounded by an outer chamber (3, Figure 5). The vapour is then fed from the outer chamber to the first permeable tube 6. <IMAGE>

IPC: G03B7/17
Filed: 1991-02-14
Abstract: In an exposure control device employed in an electronically controlled camera, an exposure value, which representing the relation between an exposure time and an aperture value, is determined in accordance with the brightness of an object to be photographed, and the open f-number of a lens is determined based on a predetermined film sensitivity. When the exposure value is determined, it is limited to a predetermined minimum exposure value. In the camera, the minimum exposure value is compensated in accordance with the film sensitivity of the film to be used.

Patent GB-918479-A (GB)
IPC: C10K1/00
Abstract: 918,479. Cold separation of gas mixtures. CONCH INTERNATIONAL METHANE Ltd. Oct. 11, 1961, No. 36442/61. Addition to 894,102. Class 8(2). Removal of solidifiable impurities e.g., hydrogen sulphide and carbon dioxide from a crude gas e.g., methane as claimed in the parent Specification is accompanied by removal of a contaminant gas of lower boiling point than methane e.g., nitrogen or hydrogen which is effected by liquefying the crude gas without solidifying the impurities e.g., by expansion in a turbine 2, cooling in a heat exchanger 4 traversed by cold separated constituents, expansion of crude liquid gas containing uncondensed nitrogen at a valve 8 into a chamber 9 so as to form a slurry of solid impurities, a flash-off vapour and gaseous nitrogen which is vented through a valved duct 42; the flashed off vapour being condensed by heat exchange at 10 with purified liquid methane and returning it to the slurry which is then expanded at a valve 20 into a separator 21 from which a concentrated slurry of solid impurities is withdrawn through a duct 32, pure liquid methane is withdrawn through a duct 25 and is forced by a pump 26 through the condenser 10 and by a second pump 28 through a duct 31 and the exchanger 4 to a discharge duct, and pure methane gas is withdrawn through a duet 22 and traverses the exchanger 4. In the event of the crude methane containing 7 mol per cent or more of hydrogen sulphide the liquefied gas leaving the exchanger 4 comprises two liquid phases which are separated in a decanter 6 into an upper methane rich layer of liquid which is expanded into chambers 9, 13-18 in series and into a lower layer rich in hydrogen sulphide which is expanded into a chamber 37 to form a concentrated slurry and a flash-off methane gas containing about 3% hydrogen sulphide; the cold content of the slurry and gas being recovered in exchanger 4. Flash-off vapour from separator 21 traverses an exchanger 23 in countercurrent to a minor portion of purified liquid methane leaving the pump 28 through a line 29 for return to line 27 and the so-warmed vapour is then passed through the exchanger 4 and a compressor 24 driven by the turbine 2.
