Patent GB-2196271-A (GB)
Title: Optical coatings
Inventor: PETERSON IAN ROBERT
IPC: G02B1/10
Filed: 1987-09-11
Abstract: A method of providing a damage-resistant optical coating on a component (10) comprises depositing on the component one or more transparent or semi-transparent layers (5 - 9) of predetermined thickness by forming a required number of monomolecular layers of a material of a predetermined refractive index, using the Langmuir-Blodgett process. By use of this process, the resulting transparent or semi-transparent layers are damage-resistant, particularly to large laser output pulses. Furthermore, the thickness of the layers can be very accurately controlled, and, by adjustment of the constituents of the material in the Langmuir-Blodgett trough, the refractive index of each layer can be accurately determined. The transparent or semi-transparent layers may be alternately of high and low refractive index, and the optical thickness can be controlled to provide an anti-reflective or reflective coating.

Title: Improvements in the treatment of water to remove gas-vacuolate cyanobacteria
Inventor: CLARKE KEITH BRIAN
IPC: C02F1/00
Filed: 1987-09-23
Abstract: The treatment of water to remove gas vacuolate cyanobacteria (blue-green algae) is effected by subjecting the water to a predetermined pressure by being pumped down a centrally located pipe (24) in a bore-hole (12), which is steel lined (13). This causes the gas vesicles in the cyanobacteria to collapse. The treated water is then stored in a settling tank (14) where the cyanobacteria sink to the bottom and can be removed along with any other sediment in the water. The method can be applied to decrease the amount of cyanobacteria with gas vesicles in a lake or other water impoundment.   Instead of being pumped down a pipe in a borehole, the water can be pumped to the top of a tower case located above ground, or through a pipe or water container having a diffuser or pressure relief valve connected thereto through which the water to be treated passes under hydrostatic pressure. <IMAGE>

Filed: 1987-10-20
Abstract: A pilot unit comprising: a housing 10, at least one user port (A,B, Figs. 2,3) in said housing, a pump Port P, 34 in said housing, a tank port T, 36 in said housing, spool means (21) arranged in said housing for connecting the pump port and tank port with at least one user port, and an operating element 42(,4) for operating said spool means for selectively providing a fluid communication between said ports, characterized in that at the housing a switching valve 41 is mounted, said switching valve being actuated by said operating element 42. In Figs. 8,9, pivoting of lever 42 about axis 56 from position 49 to position 50 releases a pin 43 and thereby allows spool 80 of switching valve 41 to slide upwardly by a spring 84 to connect its pump port 70 to a signal bore (78,77, Fig. 10) to generate a signal, e.g. to apply a brake. From position 50, pivoting of lever 42 to position 51 or 62 about an axis (3, Fig. 4) actuates one of the spools (21). In another form, Fig. 12, the lever 42 only pivots in one plane from position (53, Fig. 2) to position 51 or 52 and thereby actuates the switching valve 102 hydraulically via the pilot unit 101 and a changeover valve 114. <IMAGE>

Title: Control arrangement for a phase shift keying system
Inventor: BATTY NEVILLE GEORGE
IPC: H04B10/64
Filed: 1987-11-30
Abstract: In a control arrangement, for phase shift keying system, phase control is provided by means Z, W arranged to periodically dither the phase of a local oscillator V by adding and subtracting a phase shift to the output signal of the local oscillator. Integration means M,N is provided and arranged to integrate the moduli of received bit amplitudes during each addition and subtraction (dither) period. The difference P in the integrated valves during respective addition and subtraction periods determines a basis phase level upon which the dither is superimposed. For more extreme differences, frequency control S,T,X,U is also active. The dither enables effectively, narrow bandwidth for good control, and wider bandwidth for acquisition. <IMAGE>
Patent GB-2214025-A (GB)
Title: Object location
Inventor: DADDS ALAN FREDERICK
IPC: G01S11/02
Filed: 1987-12-22
Abstract: To locate an object emitting a 360 degree scanning signal, and more particularly to resolve ambiguity of position when two or more such objects emit non-synchronised but similar signals circles representing the locus of possible positions of emitters are obtained by measuring the time t between reception at detectors 10, 12 and T between consecutive receptions at one detector. All the possible fixes in the field of view of the detectors 10, 12 are determined as circles which pass through the signal detectors 10, 12 and each of the possible object positions are computed and those fixes which do not correlate with the circles calculated are treated as ghosts. Each circle is calculated by determining the angle A=360to DIVIDED T that an arc of a circle bounded by the detectors 10, 12 subtends at an object 14 and using the angle A and the known distanced between the detectors 10, 12 to calculate the radius R of the respective circle. <IMAGE>

Patent GB-2206594-A (GB)
Title: Polymers used as gels for electrophoresis
Inventor: KOZULIC BRANKO
IPC: G01N27/26
Filed: 1988-06-10
Abstract: A novel synthesis of N-acryloyl-tris-(hydroxymethyl)aminomethane (NAT) is described. The polymerization kinetics and transparency of the poly(NAT) gels crosslinked by a crosslinker (CL) e.g. N,N'-methylenebisacrylamide (Bis), i.e. poly(NAT + Bis) polymer, are shown. Poly(NAT + Bis) gradient (4-24 %) gels were prepared and found to resolve native proteins according to their size. The exclusion limit of these gels is over 3 x 10<6> Da. This is more than threefold higher than the exclusion limit of the polyacrylamide gradient gel of the same concentration. Therefore poly(NAT + CL) gels are better than polyacrylamide gels for the resolution of large proteins. It was demonstrated that poly(NAT + CL)-polyacrylamide composite gels could be prepared. The poly(NAT + CL) gels were found to be advantageous also for isoelectric focussing in carrier ampholytes or immobilized pH gradients. Poly(NAT + CL) gels are also very good for separation of nucleic acids. The resolution is particularly good in the range between several hundred to 4-5000 base pairs. Under the optimized conditions, DNA molecules of more than 20 kbases can be perfectly resolved.

Title: Automated mineral identification and rock characterization
Inventor: CLELLAND WILLIAM DONALDSON
IPC: G01N23/22
Filed: 1988-09-06
Abstract: A computer controlled process for analyzing and characterizing polished mineral samples uses back-scattered electron (BSE) imaging of at least one field of view of a sample to obtain BSE information data and inelastic electron scattering X-ray sampling of said field of view. Said BSE information data are digitized and are directly converted into grey level information data in order to obtain rock matrix and pore network information data. Individual objects in said field are defined automatically from said BSE information data and such defined objects are investigated by exposing the said objects each as a whole to high resolution inelastic electron scattering X-ray object scanning, yielding X-ray spectrum data of atomic elements in said objects by means of which ratio classification data are derived for determining mineral abundancies in said sample. <IMAGE>

Patent GB-2217137-A (GB)
Title: Tracking system and method for time-discontinuous signals
Inventor: GANDY CHRISTOPHER
IPC: G01S3/32
Filed: 1989-03-10
Abstract: Broadcast television signals transmitted from a moveable source such as a helicopter may be transmitted using a radio-frequency link. The transmitter may be tracked by a receiving antenna using the principle of higher order mode- synthesis by which the beam of the receiving antenna is squinted to a variety of directions about its boresight direction. The strength of the received signal is measured in each direction and the antenna is steered to adjust the boresight direction accordingly. To alleviate porblems with artefacts caused by the beam squinting, squinting is performed in the field blanking interval. To reduce the effects of multipath propagation caused by helicopter rotor blades squinting in all chosen directions is performed during a single television field blanking interval. The squinting of the receiving antenna may be achieved by providing slots in the walls of the receiving horn antenna, the slots being coupled to waveguide stubs short-circuited by pin diodes, or by a 'back wall'. The auxiliary waveguides may be simple open-ended waveguides, placed above and below the main horn aperture and equally disposed about the H-plane mid-point of the main aperture. Squinting of the beam may thus be carried out in the up, down, left and right directions. <IMAGE>
