Title: Optical fibre laser
Inventor: HANNA DAVID COLIN
IPC: H01S3/06
Filed: 1989-12-22
Abstract: PCT No. PCT/GB90/01936 Sec. 371 Date Aug. 20, 1992 Sec. 102(e) Date Aug. 20, 1992 PCT Filed Dec. 11, 1990 PCT Pub. No. WO91/10272 PCT Pub. Date Jul. 11, 1991.An optical fiber laser includes an optical fiber having a core (14), an inner cladding (12) surrounding the core and an outer cladding (16) surrounding the inner cladding and core. The core (12) is doped with a first laser-active material, preferably, thulium. The inner cladding is doped with a second different laser-active material, for example, neodymium and is pumped by a multimode pump light source such as a diode array. Pumping of the inner cladding (12) causes laser emission in the inner cladding material which, in turn, serves as pump radiation for the laser-active dopant in the core (14).

Title: Tactile floor for the partially sighted
Inventor: WILSON ADRIAN
IPC: E04F15/10
Filed: 1992-08-03
Abstract: A floor structure 10 has an underfoot surface of foot discernable tactile projections 12 and is divided into four zones 14, 16, 18 and 20, radiating outwards from a reference point 30. The projections of each zone are of different shapes to those of the other zones. Each zone is sub-divided into regions 32 each of which has a uniform array of projections 12 of the same size. The uniform array of projections and the size of the projections change progressively from one region to another from the reference point 30. A visually impaired person may gain an understanding of their orientation and distance from the reference point by touch using their feet. Each zone may be of a different colour with the regions 32 within each zone being of varying shades of that colour from the reference point. The floor may be used where the partially sighted or blind need to know their position on it, e.g. a stage or sports arena. <IMAGE>

Title: Flow control valve
Inventor: BUFFEY MICHAEL JOHN
IPC: F16K5/04
Filed: 1992-08-12
Abstract: A fluid flow control valve has a valve chamber 12 with inlet and outlet apertures 13 and 14. A valve element 19 with a manually operable knob 21 has an outer surface in sliding contact with the wall of the chamber 12 and is angularly movable in the latter. A resilient seal member 23 is seated in a recess in the valve element 19 and seals with the chamber wall around the inlet aperture 13 in a valve closed condition. A cut-out 22 in the valve element 19 serves to interconnect the inlet and outlet apertures 13 and 14 in a valve open condition. A seal member support 24 extends transversely across the inlet aperture 13 and serves to prevent bulging of the seal member 23 into the aperture 13 as the valve element 19 is being moved into the valve closed condition. <IMAGE>

Title: Method and apparatus for the alignment of several machine units arranged in series
Inventor: GUARALDI GLENN A
IPC: B41F13/00
Filed: 1992-08-21
Abstract: A method for aligning a series of printing machine units 36, 38, 40 on a base 42 comprises the steps forming alignment holes 28 in side frames 12, 14 of printing machine units 36, 38, 40 to be aligned, and correcting the locations of the holes 28 to effect a correction in the locations of the frames 12, 14 in which they are formed. The holes 28 are formed in positions which have accurate relationships to the positions of function specific openings eg roller bearing holes 20 in the parts 12, 14. An adjustment in the locations of the holes 28 via adjustment of the frames thus effects a correction in the locations of the function specific openings. The holes 28 enable an alignment of parallel frames 12, 14 of a single machine unit (eg 36) as well as alignment of several machine units 36, 38, 40 arranged one after the other in series. <IMAGE>

Title: Method and apparatus for manufacture of synthetic filaments having inherent     twist or curl
Inventor: SLACK PHILIP TREVOR
IPC: D01D5/23
Filed: 1994-04-30
Abstract: Synthetic filaments having an inherent twist or curl are prepared by continuously drawing filaments from a spinneret, blowing a gaseous cooling medium onto the drawing filaments between the spinneret and a first take-up element to establish a temperature gradient through the thickness of each filament and subsequently stretching the filaments and chopping them into desired lengths. The filaments may be subjected to cooling after passage from the first take-up element, to temperature controlled stretching after said cooling and, to increase the curl of the chopped filaments, to heat treatment after chopping. Cooling air may be fed from fan 31 through chiller 32 and duct 33 to the spinneret head 12, being directed against the filaments leaving the head by circumferential slot 34 formed at the end of duct 33. <IMAGE>

Title: Self-shielded transverse gradient coils
Inventor: WESTPHAL MICHAEL
IPC: G01R33/385
Filed: 1995-06-16
Abstract: Transverse gradient coils for MRI or NMR spectroscopy comprise windings, which may be of streamline type, on inner and outer layers Zix and Zax. The inner and outer layers are connected by windings on a layer V+x lying in a radial plane adjacent the z = 0 plane. The axial separation between the V + x plane and the corresponding V - x plane of the coil portion on the other side of the z = 0 axis is less than the radial separation of the inner and outer layers. The coil exhibits reduced stray field. Each transverse (X or Y) gradient coil comprises four of the coils shown in figure 2 (figure 4a). The Y gradient coil may be enclosed in the X gradient coil (figure 5). Alternatively, the Y gradient coil may have its connecting layer in an axially outer radial plane (figure 6), with some of the outer windings extending outwards therefrom. <IMAGE>

Title: Piston and cylinder assembly
Inventor: KITA KAZUSHI
IPC: F15B15/14
Filed: 1995-08-03
Abstract: A first cylinder 4 of a smaller diameter and a second cylinder 6 of a larger diameter are connected in a coaxially intercommunicating state. A first piston 13 of a smaller diameter which is hermetically slidable within the first cylinder is mounted on a rod 12 which is commonly passed through the two cylinders in such a way as to permit the first piston to move also in the second cylinder. Received in the second cylinder is a second piston 17 which is hermetically slidable only in the second cylinder and which is adapted to be integrally coupled with the first piston 13 during movements within the second cylinder. The chamber 30a' at the head end of the second cylinder 6 is open to the atmosphere when the piston 17 is located at its return end position and is closed from the atmosphere when the piston 17 moves away from said position. <IMAGE>

Title: Improved spectrometer
Inventor: PADGETT MILES JOHN
IPC: G01J3/447
Filed: 1994-07-11
Abstract: A Fourier-transform spectrometer contains a birefringent optical component, removing the need for a Michelson interferometer used in conventional instruments. A suitable birefringent element, such as a Wollaston prism, is used to introduce a path difference between two light polarisations. Use of an extended light source so that all areas of the birefringent component are illuminated simultaneously ensures that different positions on the birefringent component correspond to different path differences between the two polarisations. A Fourier-transform of the resulting interferogram at the detector results in the spectral distribution of the input light being obtained. The use of an extended light source permits a Fourier-transform spectrometer with no moving parts to be achieved. <IMAGE>
