Title: Measuring and controlling deposition on a piezoelectric monitor crystal
Inventor: WAJID ABDUL
IPC: G01B17/02
Filed: 1990-10-03
Abstract: The thickness and rate of growth of a deposited film (13) is monitored using a piezoelectric crystal sensor such as an AT-cut plano-convex quartz crystal (10). The frequencies of the fundamental frequency and another resonance mode are measured prior to deposition, and the change of these two frequencies is monitored during deposition to obtain the areal mass density of the deposited material. A frequency generator (14) provides accurate sweeps of frequency which are applied to the crystal (10), and the crystal response is supplied to a phase detector (22) to identify the positions of the resonance frequencies. The acoustic impedance ratio Z of the deposited material relative to the fresh crystal is computed from the resonance frequencies for the coated and uncoated crystal. The same crystal can be used to control the growth rate of several successive layers of different materials. <IMAGE>

Movement of the projections 26 causes a radially outward load to be applied to the blade root 20 which inhibits radial movement of the blade root 20 in the groove 14. <IMAGE>
Patent GB-920475-A (GB)
IPC: C08G18/83
Abstract: 920,475. Polyamines from polyisocyanates. FARBENFABRIKEN BAYER A.G. July 5, 1961 [July 9, 1960], No. 24363/61. Class 2(5) [Also in Group IV(b)] Polyamines are produced by reacting an aliphatic or cycloaliphatic polyisocyanate, or an adduct prepared by reacting such an isocyanate with a polyhydroxy compound and containing free isocyanate groups, with amidosulphonic acid (HO.SO 2 .NH 2 ) in aqueous solution. The -NCO groups are thereby replaced by -NH 2  groups, but some of the -NCO groups react with water and thus lengthen the chain through urea-type linkages. At room temperature, the urea-linkage-forming reaction is suppressed, but at ca. 40‹C. and above, the products have a higher molecular weight and lower amine-group content. The isocyanates are preferably stirred into the amidosulphonic acid solution, at room temperature if low molecular weight products having a high NH 2  content are desired, and the mixture heated to complete the reaction at up to 50‹C. The initial emulsion changes a solution on completion of the reaction, and the amine may then be precipitated by the addition of a base. In the examples, (1) a polypropylene glycol (OH number 270, mol. wt. 410)-hexamethylene diisocyanate adduct; (2) as (1), the polyglycol having OH number 112, mol. wt. 1,000; (3) as (1), octaethylene glycol ether replacing the polypropylene glycol; (4) hexamethylene diisocyanate per se are used. Other isocyanates which may be used are: tetra- and hexamethylene diisocyanate, p-cyclohexylene diisocyanate, their adducts with polyols, e.g. 3 mol. hexamethylene diisocyanate with 1 mol. trimethylol propane. Adducts of polyisocyanates with linear or branched polyethylene glycol ethers, polypropylene glycol ethers, polyesters, polytetrahydrofurans, polythioethers or polyacetals may be used. The products react with isocyanates at room temperature, are suitable as smoothing agents for textiles or stripping agents for vat dyeings, and may be used to harden epoxy resins.

Patent GB-2256956-A (GB)
Title: Security enclosures
Inventor: MACPHERSON HUGH
IPC: G08B13/12
Filed: 1992-06-05
Abstract: A security enclosure comprises two layers 12, 14 of electrically responsive material separated by a layer 16 of auto-combustible insulating material. The layers extend over the whole area of the enclosure. In the event of attempted penetration through the layers by means of laser or other non-physical penetration involving elevated temperature, the auto combustible insulating material layer is ignited, the subsequent decomposition of the insulating layer causing the electrically responsive layers to come into contact with one another causing a change in their electrical characteristics which may be detected by a detection circuit 24. The electrically responsive layers may comprise fibrous material in which the length of the fibres is greater than the thickness of the insulating layer so that piercing the enclosure forces fibres from one layer into contact with the other layer, which may also be detected electrically. <IMAGE>
Patent GB-2273597-A (GB)
Title: Traffic light control systems
Inventor: LUX TRAFFIC CONTROLS LIMITED
IPC: G08G1/097
Filed: 1992-12-17
Abstract: A basic system has traffic lights at opposite ends of an obstruction. When the road between the lights is level, traffic can be expected to pass each way in the same time, but where there is a gradient, uphill traffic will be slower than the downhill. The system provides compensation for this, enabling the all-red or inter-green period following green at the downhill end to be longer in proportion to the slope than the all-red or inter-green period following green at the uphill end. With lights controlling junctions or crossroads, the compensation is applied separately for the lengths between the lights and the intersection, and the complete inter-green times are derived from the adjusted part-times associated with each light.

Title: Apparatus for removing surplus from a stream of fibrous material
Inventor: HEITMANN UWE
IPC: A24C5/34
Filed: 1993-01-28
Abstract: A tobacco stream which contains a surplus of tobacco particles 26 is conveyed in a channel 1 past a trimming device which serves to remove the surplus and has two disc-shaped tobacco engaging members 11a, 11b extending through openings in the sidewalls of the channel and into the stream in such a way that the surplus is located at one side and the remainder of the stream is located at the other side of the plane of the tobacco engaging members. These members are rotated in opposite directions, and their marginal portions come nearest to each other at a point normally midway between the sidewalls. A rotating tube is disposed at the one side of the tobacco engaging members and has a serrated or smooth cutting edge which removes the surplus only, or practically only at the aforementioned point. Such surplus is evacuated by suction through the tube whose axis makes an oblique angle with the direction of advancement of the stream in the channel.   <IMAGE>

Title: Video data compression system using two dimensional spatial frequency sub-band  separation
Inventor: WILKINSON JAMES HEDLEY
IPC: H03M7/30
Filed: 1993-02-04
Abstract: An array of image data 2 is separated into two dimensional spatial frequency sub bands by alternately applying vertical A', C' and horizontal B', D' filtering to the lowest frequency sub band output from the previous stage. The other sub bands are left unaltered. The combination of the sub bands is the complimentary process whereby the lowest 28 and next lowest 30 spatial frequency sub bands are combined using alternating ones of horizontal E', G' and vertical F', H' interpolation. The use of decimators (38, 44, Fig. 4) to effect low pass filtering avoids the need to increase the number of bits needed to represent each data value within these low pass bands. <IMAGE>

Title: Method for controlling the temperature of an interior
Inventor: STRAUB WOLFGANG
IPC: G05D23/20
Filed: 1994-09-01
Abstract: In a method for controlling the interior temperature of vehicles in which air is allowed to flow into the interior from outside, the desired temperature (Tbs) of the inflowing medium is initially set by means of PI control in a starting phase only if the initial interior-temperature error values (dTi) are small, whereas, in the case of larger initial control imbalances, an offset desired temperature for the medium acting thermally on the interior is first of all set in such a way that the interior-temperature error is counteracted to the maximum extent by the inner control loop. The range of small interior-temperature errors is thus regained as rapidly as possible, after which PI control is carried out. <IMAGE>
