Title: Adhesive coated sheet materials
Inventor: GALLAGHER NICHOLAS D
IPC: C09J7/21
Filed: 1984-06-08
Abstract: Adhesive coated sheet materials particularly adapted for self-releasable adhesive tapes as described. The invention comprises the use of a coated base web and an adhesive layer selected so that the base web coating has a greater affinity for the adhesive than for the base web. The result is an adhesive sheet material that, when bonded to itself by applying the adhesive against the opposite side of the sheet material, may be readily peeled apart by delamination of the coating on the base sheet. This combination may be used as a bander for coiled materials such as rolls of stamps, or for stacks of currency, and the like.

Title: Optical monitoring apparatus
Inventor: MACFADYEN DAVID NIALL
IPC: G01D5/38
Filed: 1984-06-27
Abstract: The apparatus (10) comprises a broad band light source (11) coupled by optical fibres (12) to a spectrometer (15) arranged to provide spatial separation of the wavelengths of the light emitted by source (11). The spatially separated wavelengths are incident on a transducer formed by gratings (14A,14B) and the resultant light is collected by collector (16) and transmitted by fibre optics (17) to an interpretation means (20), interpretation means (20) comprises spectrometer (21) providing spatial separation of the wavelengths of the light provided by fibre (17) and these are incident on a CCT array (22) which is driven to provide electrical output signals in series. The electrical output signals are fed through a low pass filter (24) to a comparator (25) which also receives a reference signal from an oscillator (26). Comparator (25) measures phase difference, the magnitude of which corresponds to the variation sensed by transducer (14A, 14B) arising from variation of a parameter being measured. It is started that pressure may be measured using an elasto-optic (photoelastic) material e.g. polyurethane rubber or that temperature may be measured using a temperature sensitive birefringent material e.g. lithium niobate. <IMAGE>

Title: Switch/display units
Inventor: LEVIEN DAVID ANDREW
IPC: H03K17/18
Filed: 1984-10-18
Abstract: A switch/display unit comprises a dot matrix electro-luminescent display, having two sets of parallel elongate electrodes (11), (14), one set being inclined to the other, these sets being applied to opposite sides of a layer of phosphor (13). A transparent dielectric panel (10) is superimposed in front of the electro-luminescent display, so that the first set of electrodes (11), which are formed from a transparent conductive material, abut the rear surface of the dielectric panel (10). A transparent conductive layer (12) is formed in front of the dielectric panel, so that it will capacitively couple electrodes of the first set of electrodes (11) with other electrodes of the first set of electrodes (11) or other electrodes on the rear surface of the dielectric panel. This capacitive coupling may be varied by touching or moving the conductive layer (12). By applying read pulses to one of the sets of electrodes that are capacitively coupled via the conductive coating and sensing the pulses transmitted to the other electrodes, actuation of the switch can be detected. Means is also provided to apply ignition pulses to the first and second sets of the elongate electrodes (11), (14), so as to provide an electro-luminescent display which may change in response to actuation of the switch. Several such switch/display units may be combined into an array, utilising a common dielectric panel and other components. <IMAGE>

Title: Liquid-vapour contact method and apparatus
Inventor: GLADMAN DAVID CHARLES FLETCHER
IPC: F25J3/02
Filed: 1986-09-12
Abstract: In a distillation column used in the separation of air, a liquid stream of composition intermediate those occuring at the top and bottom is taken from the column 2 through passage 24 and is reboiled in an external heat exchanger 28 by heat exchange with heat exchange fluid 32. The resultant vapour is returned to the column through the distributor 30. Its composition matches that of the vapour in the vapour space to which it is returned more closely than that of the vapour in the vapour space above the tray from which the liquid is taken for reboil. The heat exchange fluid is other than one which is taken from a liquid-vapour contact column passed directly to the heat exchanger 26, and then returned directly to the column from which it was taken. The distillation column is preferably the lower pressure column of a double column system, and the heat exchange fluid may be air which is introduced into the column at a level above that from which the liquid stream of intermediate composition is taken. The invention makes possible operation of the column at greater efficiency while still obtaining pure products at the top and bottom of the column. <IMAGE>
