Title: Laminar flow nacelle
Inventor: LAHTI DANIEL JOHN
IPC: F02K3/04
Filed: 1983-10-24
Abstract: An improved nacelle is provided for housing an aircraft engine and reducing aerodynamic drag during aircraft operation. In one embodiment, the nacelle houses a gas turbine engine and forms the fan cowl 24 of a turbofan engine having a fan 16 and comprises a leading edge and a trailing edge, having a reference chord extending therebetween, and an outer surface which is continuous from the leading edge to the trailing edge. The outer surface includes a forward portion, an intermediate portion and an aft portion and has a profile defined by a varying thickness measured perpendicularly from the chord to the outer surface. The profile has a maximum thickness at the intersection of the forward and intermediate portions, which intersection is located greater than about 36% and probably at 56% of the chord from the leading edge, and is effective for increasing laminar flow over the nacelle for reducing aerodynamic drag. The flow is turbulent aft of the maximum thickness. <IMAGE>
Patent GB-2139045-A (GB)
Title: Transmission systems
Inventor: HEDDERLEY DAVID LESLIE
IPC: H04L7/10
Filed: 1984-04-11
Abstract: To overcome the requirement for a synchronising header on signalling bursts in a burst mode signalling system, the received signal is split at the receiver and is forwarded to a delay line 3 and a synchronisation circuit 4. A decoding circuit 5 receives the delayed signal from the delay line 3 and, concurrently, receives carrier and digit synchronisation values from the synchronisation circuit 4. Thus digital data may be extracted from the first digit of each burst since the decoding circuit 5 is synchronised to the values already determined by the synchronisation circuit 4. Since synchronisation values may be determined for one burst whilst a preceding burst is being decoded, a greater information density in any given signalling system may be achieved. <IMAGE>

Title: Rotary separator
Inventor: HUNT NOEL
IPC: B07B13/04
Filed: 1984-04-17
Abstract: A rotary separator comprises a casing having side walls (12) and a further wall (17) between a rotary shaft (14) and one of the side walls. The shaft carries axially spaced sets of four equi-angularly arranged blades (16) which at adjacent axial locations are relatively angularly staggered. Material is fed vertically to the space between the wall (17) and the shaft (14) and the shaft rotates against this flow. Material (29) below a predetermined size, as allowed for by the blade dimensions and spacings, passes down between the blades and the wall (17) and out to a collection. Material (30) greater than said predetermined size is gathered by the blades and carried to the opposite side of the casing where the material (30) is released under gravity or by engagement by blade elements (28) to fall down a chute (24) to a position spaced from the reception means (20, 21, 22), thereby separating it from the smaller material. Holes (27) in the chute (24) allow fine material transported on the larger material to return to the smaller, separated material. <IMAGE>

Title: Sample inlet system for an electron capture detector
Inventor: WELLS GREGORY JAMES
IPC: G01N27/66
Filed: 1984-09-04
Abstract: An electron capture detector for use with capillary column 111 is provided with a sample inlet comprising a tubular anode 115 through which sample molecules and a make-up gas are introduced into the detector cell 120. The tubular anode 115 has side ports 122. The inner surface of the anode 115 is protected by an insulating tube 114 so that the capillary column 111 can be extended to a point beyond the side ports 122 without the fear of its electrical contact with the anode 115. This allows the sample molecules to flow nearly entirely in the center section of the cell. The peripheral regions of the cell where a radioactive foil 125 is disposed is swept nearly entirely by the make- up gas entering the cell through the side ports. This has the effects of reducing sample dilution by the make-up gas and sample loss due to contact with the detector walls. <IMAGE>

Title: Method and apparatus for measuring a magnetic field
Inventor: POPOVIC RADIVOJE
IPC: G01R33/025
Filed: 1985-03-28
Abstract: Apparatus for measuring a magnetic field (HM), which apparatus may form part of the measuring means of an electricity meter, comprises an electromagnetic first control circuit (2, 8b, 3b, 4, 5) and an electrical second control circuit (2, 8b, 3c, 9) which are operated alternately. A sensor (2) measures a magnetic field difference (HM - HK) between the magnetic field (HM) to be measured and a compensation magnetic field (HK). A switch (3) feeds the measurement result either to the first or to the second control circuit. The first control circuit (2, 8b, 3b, 4, 5), by way of a first controller (4), controls a compensation current (IK) which flows in a coil (5) and in that way produces the compensation magnetic field (HK), so that the voltage (UO) at the output of the sensor (2) becomes zero. The second control circuit (2, 8b, 3c, 9) detects and adjusts the working point of the sensor (2) in such a way that the magnetic field (HM) to be measured is equal to the sum comprising the compensation magnetic field (HK) and an apparently-present magnetic field. The apparently-present magnetic field is equal to a multiple of a predetermined reference value (HR) of the compensation magnetic field (HK), corrected by the effective value of all 'offset' voltages in the electrical second control circuit (2, 8b, 3c, 9). <IMAGE>

Patent GB-2183332-A (GB)
Title: Cinefilm fault detector
Inventor: NIGHTINGALE ERIC GORDON
IPC: G01N21/21
Filed: 1985-11-22
Abstract: Tears, creases or other faults in a cinefilm (5) are detected whilst the film is being transported on rollers (1, 2, 3) during processing. An image of a slit (S) in a mirror (10) is focused onto the surface of the film at P. When the film surface lies exactly at the focal point the image of the slit is reflected back to its original position. However any deviation in the position of the film surface, due e.g. to a crease or tear (as shown exaggerated at 5') causes a broadening of the reflected image, which is therefore captured by the mirror (10) and reflected to a photodetector (12). The output signal of the photodetector is used to generate an alarm signal so as to disable drive (4) to the rollers (1, 2, 3). A beam splitter (9) and a further photodetector (11) monitor the total reflected optical intensity to enable variations in the output of a light source (6) to be compensated. Polarised light may be employed. <IMAGE>
Patent GB-860525-A (GB)
Abstract: 860,525. Surveying instruments. TARCZYHORNOCH, A. May 27, 1959 [June 4, 1958], No. 18074/59. Class 97(2) To determine the angles made by sides of triangles and polygons with the north when making surveys, the theodolite is provided with a .scale which determines the angle made by the tangent or chord of a star-track to the horizontal or vertical. Two :hairs are provided in the field of view of the telescope the upper one having two marks a,b, which are spaced apart a ,distance equal to the distance between the hairs and the lower one having graduations, the zero and unit points of which correspond to points a and b respectively. On observing a star track which moves downwardly from left to right in the field of view the image is arranged to cross the upper hair at point a and on reading from the scale where the image crosses the lower hair a direct reading is given of the cotangent of ;the angle between the tangent to the star track .and the horizontal. From this, it is shown in the Specification, the required angle .can be determined. If the itelescope is turned to its  second position so that the hair with the divisions is the top,image of a star moving upwardly may be aligned with point b and the position noted on the scale where the image crosses the now upper hair. The divisions are marked with two sets of numbers to facilitate this. A second scale may be provided normal to the first one for use for instance where the angle between the tangent to the star track and the horizontal is much smaller than 45 degrees. If the marks at a and b and the scale divisions are long enough, the sun may be observed using the lines as tangents to its surface.
