Patent GB-2279737-A (GB)
Title: Photoelastic stress analysis
Inventor: STOCKLEY BARRIE CARLTON
IPC: G01L1/24
Filed: 1993-02-08
Abstract: Polarized light from a polarizer (12) is passed through a stressed birefringent object (14) and an analyser (16) to produce a fringe pattern representative of the stress in the object (14). The fringe pattern is observed with a CCD camera (18) and intensity information of the pattern is input to a computer (22). The process is repeated for at least two wavelengths of light and the information for the different wavelengths is combined to form a stress map of the object (14) for display on a VDU (24). <IMAGE>

Inventor: ATKINSON ALEX
IPC: D02G1/16
Filed: 1995-02-02
Abstract: A method of producing a textured thread 10 comprises the steps of providing at least two multi-filament yarns 1, 2, drawing the yarns over a hot contact point 4 to stretch the yarns, shrinking the yarns by a controlled amount e.g. by wrapping round a hot shoe (5), intermingling the yarns in an intermingling device 3 to provide a single intermingled thread, drawing the intermingled thread from the device and winding the thread onto a storage reel 11, the steps of intermingling, drawing and winding being carried out at ambient temperature.

Title: Valve assembling method and assembled valve checking method
Inventor: MAKINO SUEYOSHI
IPC: B23P19/04
Filed: 1992-07-29
Abstract: A valve assembling and checking method for mounting successively a spring (4) longer than the depth of a valve hole (2) formed in a valve body (1) and a spool (3) into the valve hole, comprises the steps of: pressing the spring (4) against the side wall of the valve hole (2), to vertically hold the same by means of a pusher (52); engaging the spool on the spring; moving the spool (3) immediately above the valve hole, to allow the spool to fall from the spool holding means (30), and repeatedly clamping and unclamping the spool to adjust the location of a spool which erroneously engages with an edge of the valve hole (2) so as to be correctly received in the valve hole (2). Further assembly procedures described are concerned with checking the correct installation of the spring and spool by displacing the spool, Figure 10, downwards and measuring the resistive forces at different displacements, supporting a short spring in an elevated position Fig 9(B) during location of the spool on the spring, and insertion of a spool with a freely-swingable cage, Figure 11. <IMAGE>

Title: Dual-mass flywheel assembly
Inventor: WEISS MICHAEL
IPC: F16F15/16
Filed: 1995-07-17
Abstract: A flywheel assembly comprises a first flywheel (1) connected to an input drive, a second flywheel (24) engaging it through a torsional vibration damper (13) and allowed limited relative angular movement in relation to the first and a controllable frictional damping device (105), by means of which a frictional connection between the two flywheels can be produced under predetermined conditions of operation. The damping device (105) is operated when at least one measured characteristic associated with a predetermined operating condition is detected, eg an excessive speed difference between the flywheels 1, 24 indicative of a resonance condition. The damping device can be operated by the actuator for the friction clutch 100, movement of which past the point at which the clutch disengages causing the diaphragm spring 34 to actuate the device via a lever 43. The diaphragm spring may itself form part of the friction damper (Fig. 4) or the friction damper may have a separate actuator (Fig. 3). <IMAGE>

Title: Helmet visor release apparatus
Inventor: THOM IAN GRAHAM
IPC: A62B18/00
Filed: 1995-08-01
Abstract: The invention provides a helmet visor release apparatus comprising two manually operable catches, each having a first portion (4) on a helmet (1) arranged to releasably engage with a respective second portion (5) on a visor (2), and a linkage mechanism e.g. a cable (6) connected to both catches such that manual release of one catch causes the other catch to be released. Thus the visor may be released from a closed position by single-handed operation without obscuring the wearer's view. The visor can also be released by opening both catches manually, thus enabling the visor to still be released in the event that the linkage mechanism should fail.

Title: AC electric power switching arrangement; avoiding inrush currents in inductive loads
Inventor: HUGHES DAVID GARETH
IPC: H01H9/56
Filed: 1995-10-12
Abstract: The arrangement has a first switch 18 connected in parallel with a second switch 20 between an AC supply 12 and a load 14, particularly a transformer fed load, and control means to switch the load on by initially turning the second switch 20 on in a supply-synchronised manner and substantially immediately thereafter turning the first switch 18 on, the load being switched off by turning off switch 18 then switch 20. The arrangement may be used for a transformer fed industrial furnace having resistive heating elements with duty cycle power control. The switch 18 may be solid state but is preferably a contactor, and the second switch 20 may be formed by thermionic devices, MOSFETs, IGBTs or particularly thyristors. For a three phase supply with a R-Y-B phase sequence, a four step turn on sequence may be used. In step 1, the R and B thyristors are turned on at 30 - 90 degrees after a positive going zero crossing of the R-B voltage waveform; in step 2, the Y thyristors are turned on 150 degrees after the R-B voltage positive going zero crossing; in step 3, the contactor 18 is closed; and in step 4, the R, Y and B thyristors are turned off. To turn the load off, the R, Y and B thyristors are all turned on, then the contactor 18 is opened, then the Y thyristors are turned off at zero current flow on the positive going edge of a current cycle, and then the R and B thyristors are turned off at zero current flow on the next positive going edge of the R-B current cycle. Alarms may be provided for loss of any supply phase, loss of phase reference, loss of power to the contactor operating coil, change in phase rotation, and change in operating frequency. <IMAGE>

Title: Acquiring data from devices
Inventor: MASE ATSUSHI
IPC: G06T7/00
Filed: 1995-11-22
Abstract: A data processing method which makes it unnecessary to run a user application program describing detailed conditions under which data from a device are acquired each time a system is started. A main controller 10 forms a text format file defining a data acquisition condition for a PLC 30a, b, c from which data is to be acquired so that the condition is associated with a label name, the condition including an interval for supervising the status of the PLC and the operation status of the PLC for setting a trigger condition for starting data acquisition. When receiving the label name and the corresponding data acquisition condition from the main controller 10, a subcontroller 20 develops and stores the received condition in a memory 22 so that the condition is associated with the label name. When receiving only the label name from the main controller 10, the subcontroller 20 compares the condition stored in the memory 22 with data of the PLC, acquires data from the PLC when the condition is satisfied, and transfers the acquired data to the main controller 10. The system may include a second main controller (Fig 16).

Title: Protective sheath for key
Inventor: PRATT SHARON
IPC: E05B63/00
Filed: 1996-04-09
Abstract: A retractable protective device for covering the face of a key when not in use comprises a sheath 5 which is slidably mounted on the shaft of a key 7 between a forward position in which the face of the key is covered from view and a retracted position in which the face of the key is exposed. The sheath is biassed into the forward position by the force of a spring 2. In use, the sheath is positioned against the lock face and the force of the spring is overcome so that the key can enter the lock. As the key is removed from the lock, the sheath returns to the forward position under the effect of the spring 2.

Title: Hydraulic power-assisted steering system
Inventor: LANGKAMP BERND
IPC: B62D5/06
Filed: 1996-05-29
Abstract: The steering system includes the servomotor and the hydraulic pump (12). The drive train (4,5) between the servomotor (6) and the steering unit contains the dynamometer (19). The hydraulic medium flow to the servomotor is regulated in such a way, that an actual power value determined by the dynamometer corresponds to a nominal value which is dependant on the manual force applied to e.g. the steering wheel. A switch valve (9) is located between the motor and pump.
