Title: Inspecting vehicle body during manufacture
Inventor: KODAMA AKIRA
IPC: B62D65/00
Filed: 1995-09-22
Abstract: Panels on a vehicle frame are inspected by irradiation, eg with a scanned laser beam, and detection of reflected light, eg by camera. The resulting profile data is differentiated to produce linear differential data which is processed to measure the degree and range of distortion. The central point of the distortion is determined from the linear profile data and a smoothed version thereof, and the range of distortion around the central point is determined from a further differentiation of the linear differential data. Alternatively (fig 20) the central point is determined from the linear differential data and the range is determined from a double integration of the linear differential data. The measurement is compared with a predetermined value to determine whether the panels suffer surface distortion. The unpainted panels may be coated with an aqueous lustering agent P, and defective panels repaired before being painted.

Patent GB-2316342-A (GB)
Title: Electrostatic coating
Inventor: HOGAN JOHN EDWARD
IPC: A61K9/28
Filed: 1996-05-08
Abstract: The invention provides apparatus for electrostatically coating a pharmaceutical tablet core with powdered coating material. The apparatus comprises a first rotary drum (12) on which a core is held in electrical isolation from its surroundings but at a potential difference to earth by an electrode which contacts the core. The core is carried past a coating station B at which particles of powder having an opposite potential difference to earth are held in a tray (18). The surface of the drum is held at the same potential difference to earth as the powder particles. The powder is attracted to the core, and not to the drum, coating the exposed surface of the core. The drum carries the coated core past a fusing station C at which a heater fuses the powder to form a continuous film coating. The core is then turned and transferred onto a second drum (12') where the other surface is coated in the same way.
Patent GB-2324573-A (GB)
Title: Gerotor pump
Inventor: YU DEQUAN
IPC: F04C2/08
Filed: 1997-12-01
Abstract: A gerotor pump (10) includes a pair of relief ports (40,42, Fig 2) superimposed on and directly communicating with the pump's inlet and outlet channels (30,32), respectively. The relief ports simultaneously communicate with a pumping chamber (34) so as to provide an intermittent controlled leak therefrom. Upon rotation of the gear members (18,20) when the volume in the pumping chamber (34) is increasing to a maximum, fluid in the pumping chamber (34) vents into the relief port (42) while continuing to communicate with the relief port (40). Upon further rotation of the gear member (18,20), when the volume in the pumping chamber (34) is decreasing, fluid in the pumping chamber (34) is prevented from venting into the relief port (40) while continuing to communicate with the relief port (42). Thus, fluid over-pressure and excessive fluid leakage from the pumping chamber (34) is limited.

Title: A coupling having a piston with a helical shear channel
Inventor: KWOKA GEORG
IPC: F16D35/00
Filed: 1997-12-17
Abstract: A coupling comprises a hub 11 having tooth formations 25 which cooperate with inner tooth formations 26 on an annular piston 14 so that the piston 14 is rotatably fast but longitudinally displaceable with the hub 11. The piston 14 is centred by springs 28, 29 and divides a viscous fluid filled annular chamber 13, in housing 12, into two compartments 32, 33 which communicate via a helical shear channel 35 in the piston 14. Upon relative rotation between the hub 11 and the housing 12, the fluid shears and is conveyed in channel 35, thereby producing a pressure increase in one of the compartments 32, 33. This pressure increase axially displaces the piston 14, against springs 28, 29, so that friction linings 38, 39, fixed to piston 14, contact respective end faces 21, 22 and causes a braking effect between the hub 11 and housing 12. An axially displaceable annular compensating piston 42 is also provided. The friction faces on the piston 14 may be replaced by interleaved inner and outer plates (78, 79, fig 2). In another embodiment the piston 14 is free floating (see fig 3).
