Title: Gas turbine engines
Inventor: ANGEL ROBERT GEORGE ANDREW
IPC: F02K3/075
Filed: 1986-06-21
Abstract: A variable cycle gas turbine bypass engine includes a first fan 1 located at the engine inlet supplying air to a compressor 2 driven by a turbine 11 and to a bypass duct 13 surrounding the compressor housing. A second fan 5 located in the bypass duct 13 is driven by a free turbine 12. A controllable area auxiliary air intake 4 and bypass duct blocker doors 3 are located between the first and second fans 1, 5, with control means effective for selectably operating the doors 3 and the intake 4 to vary in operation the bypass ratio of the engine. Thus in conventional wing-borne flight, the intake 4 is closed and the bypass duct 13 is unobstructed, and the combined exhausts from the bypass duct 13 and the turbines 10, 11 and 12 pass to a tailpipe 14, which has a vectorable nozzle 8, to produce forward thrust. In jet-borne flight, however, the doors 3 block the bypass duct 13, the auxiliary air intake 4 is opened to admit air to the second fan 5, and a vectorable nozzle 9 with associated blocker doors 3a and the nozzle 8 are operated by the control means respectively to receive air from the first fan 1 and the exhausts from the second fan 5 and the turbines 10, 11 and 12. <IMAGE>

Title: Improvements in or relating to footwear
Inventor: ROBSON ELAINE MAVIS
IPC: A43B23/30
Filed: 1988-06-06
Abstract: It is well known that during driving the rear regions of the driver's footwear will contact the floor of the vehicle and can be scuffed thereby. Ladies' high-heel shoes are particularly susceptible to this type of unsightly damage.

Patent GB-2216819-A (GB)
Title: Mixing and dispensing
Inventor: PAXTON JOHN
IPC: B01F5/00
Filed: 1989-03-31
Abstract: A valve 12 is operable by a lever 36 to allow concentrate to flow through a conduit 16 to a mixing chamber. During normal use a conduit 40 leading to the downsteam side of the valve 12 prevents any vacuum from tending to form in the outlet 34 which vacuum may tend to inhibit rapid and complete discharge of concentrate. To clean the downstream side of the valve, the valve is left closed and water from a dilutant supply valve is directed through the conduit 40 and into the outlet 34 against the downstream side of the valve. The water is then flushed out of the outlet through the conduit 16. <IMAGE>

Title: Allergy testing
Inventor: ROBERTSON PATRICIA MARY BECKET
IPC: G01N33/50
Filed: 1990-08-01
Abstract: An aqueous suspension of leucocytes is incubated e.g. in a multiwell plate with test allergen. The supernatant of the suspension is analysed for a constituent of the leucocytes released as a result of the membrane of the leucocytes being stressed or lysed by the allergen and the constituent detected by a colour change which either is visible to the eye or visible using a detecting probe. The colour change detected in wells containing allergen and leucocyte suspension is compared with the colour change detected in wells containing leucocyte suspension with no allergen and wells containing allergen only. The changes observed are compared with a standard range of colours from no or minimum allergic response to maximum allergic response. Kits for the test comprise microtitre plates, pipettes, analysis probes, sedimentation tubes and standards.

Title: Method and apparatus for the treatment of short-sightedness
Inventor: GAN CHEK SEAN JACKSON
IPC: A61F9/00
Filed: 1990-12-04
Abstract: The invention provides a physiotherapeutic method and apparatus for the treatment and cure of common short-sightedness. The apparatus comprises a device 10 having an annular body part 12 adapted to fit over a persons closed eyelid, with the inner edge 16 of the body being shaped so as to apply pressure through the eyelid to the eyeball (not shown). The pressure so applied opposes the eyeball's tendency to grow longer by simulating muscle pressure which normally occurs during movement of the eyeball. The annular configuration avoids direct pressure on the cornea and the pressure exerted by the device may be increased by the inclusion of a weighting material in the body's base. <IMAGE>

Patent GB-2253089-A (GB)
Title: Particle source
Inventor: MULLOCK STEPHEN JAMES
IPC: H01J49/40
Filed: 1991-02-20
Abstract: A particle source for producing a series of bursts of, for example, ions of predetermined energy suitable for use in a time of flight mass spectrometer includes a gun for generating the ions which is operated with an accelerating voltage that is periodically varied to ramp the energy of the ions from a first energy to a second energy. The emitted ion beam is then chopped to form bursts of ions from that part of the emitted beam in which the energy ramp exists, whereby bunching of the ions in each burst occurs due to the energy spread therein. The arrangement produces sharply defined nanosecond ion pulses using readily available power sources - in the example given the ramp voltage has a rise of 2.5kV over 30ns. If the ion pulses pass through a lens arrangement then by varying the voltage on the lens in accordance with the variation in accelerating voltage the chromatic aberration produced by the lens can be reduced. Alternatively bursts of electrons or neutral particles may be produced.
