Title: Wavelength-selective optical coupling device
IPC: G02B6/34
Filed: 1982-03-18
Abstract: A coupling device comprises input and output optical fibres 42, 44, 46, 48, 50 coupled to one face 16 of a graded refractive index rod collimating lens 12. Associated with the other face 18 of the lens 12 are a plurality of multi-layer dielectric interference filters 52, 54, 56, 58 which selectively reflect the input signals at different angles according to the wavelength and thereby direct them back through the lens 12 to the appropriate output fibre. The illustrated device operates as a multiplexer/demultiplexer, coupling optical signals having distinct wavelengths  lambda 1,  lambda 2,  lambda 3, lambda 4 between respective fibres 42, 44, 46, 48 and a common multiplex-signal fibre 50. <IMAGE>

Title: Combined hinge and deflection arrangement for an aerodynamic control member
Inventor: BRADBURY CHARLES
IPC: B64C9/02
Filed: 1982-06-18
Abstract: A hinge/deflection arrangement for mounting an aileron 21 rearwardly of the rear portion 10 of a main wing includes a hinge element 12 having a cruciform yoke 13 and a control arm 14 extending transversely of the yoke. One of the limbs of the yoke is pivotally mounted to rear portion 10 by means of bracket 11 for pivoting movement about axis XX, whilst the other pivotally carries a coupling fork 16 for turning movement about axis YY. The tail portion of fork 16 is rotatably carried in aileron 21 for rotary movement about axis ZZ. The aileron is constrained to tilt relative to the main wing about axis HH, preferably by means of a further hinge/deflection arrangement, and axes XX, YY, ZZ and HH intersect at a common point. Deflection of the aileron is effected by means of movement of a control rod 15 in the direction of its length within the plane of the main wing portion. <IMAGE>

Title: Spatially selective NMR
Inventor: RADDA GEORGE KAROLY
IPC: G01R33/483
Filed: 1982-09-06
Abstract: In a method of high resolution pulsed NMR spectroscopy, the r.f. field is deliberately made inhomogeneous and a special pulse sequence is used to ensure that the received signals emanate predominantly from a selected region in a volume of the sample. Thus, the acquisition pulse (70) from which the FID signal (72) results, and which is applied in the presence of a main uniform static magnetic field, is preceded by a preparatory treatment involving at least one (typically 4-5) r.f. pulse(s) (66) being N pi  pulses (N being integral) in respect of those nuclei of interest only in the selected region, each preferably followed by a d.c. pulse (68) giving rise to a magnetic field gradient superimposed on the main alignment field. The pulse 68 increases the amount of phase incoherence in unselected regions and is particularly useful when T2 is relatively large. Pulse 70 is typically a 30 DEG -90 DEG  pulse. The static field may be non-uniform other than in the volume encompassing the selected region. The method may be used for <31>P experiments. <IMAGE>

Title: Igniters
Inventor: TINDALL DAVID
IPC: F23Q3/00
Filed: 1983-06-24
Abstract: A gas-electric igniter 1 comprises a tube 6 which encloses concentric tubes 7 and 8 defining an annular passage 13 connected to a gas line for issuance of gas to a flame holder 14 at the front end of the igniter 1. Flame holder 14 has six axial tubes (15 and 16) spaced about the axis of the igniter 1 and communicating with the annular passage 13. Four tubes 15 pass, through an ignition zone 21 to the front end of the flame holder 14 to issue as main gas jets. The two tubes 16 have their front ends closed so that raw gas only issues through radial holes 20 as pilot gas jets which are spark ignited in the ignition zone 21 to provide a pilot flame which then ignites the main gas jets. Support tube 6 carries a deflector F which causes combustion air C, which is blown by a fan forwardly along the outside of the support tube 6, to reversely flow into the ignition zone to form a combustible mixture with the pilot and main gas jets. <IMAGE>

Title: Rotary powerslips
Inventor: CROWE WILLIAM EDWARD
IPC: E21B19/10
Filed: 1985-02-01
Abstract: Rotary power slips comprise a body 13 mounted in the rotary table of an earth drilling rig; slips 15 for gripping and releasing pipe in the rotary table; an air transfer ring 53 with concentric grooves 55 in its upper surface; an annular seal ring 33 with air passageways 37 leading via secondary fluid conduits 39 to pneumatic cylinders 21 for raising and lowering the slips; and expansive rings 61, 62 secured to the surface of the air transfer ring with their edges mounted in grooves 53.

The air pressure flows through a perforation in the expansive ring into the expansive fluid duct, and then through the air passageway and the secondary fluid conduit to the pneumatic cylinders. A pilot operated check valve maintains pressure in one end of the cylinders to keep the slips in the upper, retracted position, but opens when positive pressure is applied to the other end of the cylinders. <IMAGE>

Patent GB-859355-A (GB)
Abstract: 859,355. Testing balance of rotors. AMERICAN MACHINE & FOUNDRY CO. March 16, 1959 [March 17, 1958], No. 9084/59. Class 106 (2). [Also in Group XXVI] A machine for testing a rotor R at high angular velocities comprises a bed 1, a frame 2a fixed perpendicularly to the bed 1, a cantilever 6 in spaced relation to the bed 1, means 8 for rotating the rotor R in journals 16 on the cantilever 6 and a cover 40 reciprocably supported by the bed 1 and large enough to be drawn over and enclose the cantilever 6 and the rotor R being tested. The apparatus is devised for the testing of turbo-jet rotors at high speeds for balancing and for proving freedom from defects in design and materials. The cantilever 6 is mounted on a circular plate 4 which is connected to the frame 2a. To support the rotor R, two yokes 10, 11 are mounted on the cantilever and these carry flexure rods 18 supporting cross-beams 12, 15, between which are mounted longitudinal members 13, 14. Saddles 16, 17 are secured to the beams 12, 15 and hold the bearings in which the rotor is journalled. To prevent undesirable vibration of the beams 12, 15, a locking device 29, 30 is used. An hydraulic cylinder 37 carried by the yoke 10 forces plungers 29, 30 against brackets 19, 20 carried by the beam 12, when actuated, thus fixing the beam, and a similar device is used to clamp the beam 15. The cover 40 consists of a plurality of coaxial cylinders 40b closed at one end by a plate 40a and supported by wheels 44 running on tracks 1a. This cover is reciprocated by means of an hydraulic cylinder 45 and when it encloses the rotor R and the cantilever 6, an 0-ring in a groove 4a on the plate 4 seals the open end of the cover thus making it airtight. The plate 40a also carries two bushes 52 in which pins (not shown) are adjustably mounted, the pins engaging with complementary sockets 50, formed on the end of the cantilever 6, when the cover is engaged with the plate 4. In operation, the beams 12, 15 are clamped as described above and the rotor R is mounted in position and coupled to a motor 8. The cover 40 is then drawn over the rotor and the cantilever, and air exhausted from the interior of the cover by use of a pump 9. The rotor is then accelerated to a speed above its useful operating range to determine whether or not it will fly apart or have excessive vibration at various speeds. When this test is completed, the rotor's speed is reduced and the vibration pattern at various speeds recorded. Finally, the rotor is dynamically balanced at a predetermined speed. The cover 40 as well as providing an airtight seal also acts as a safetybarrier in case the rotor should fly apart. To indicate the vibrations, seismic-type vibration detectors 22 are mounted on the beams 12 and 15, these detectors being connected to electronic indicating equipment.
