Title: Traction current monitoring arrangement
Inventor: KEMP ROGER JOHN
IPC: H02H7/08
Filed: 1989-12-18
Abstract: An arrangement for monitoring the current (I) drawn by a railway traction drive system indicates when interference may occur with a track-based signalling system. The current (I) is measured by a transducer (9) at a point between the supply filter (14) and the power switching means (4) of the drive system. A first signal (20) representing the current (I) at the predominant frequency of the switching means is derived from the transducer output (19). A second signal (18) representing a predicted current at the predominant frequency is derived from currents (17) in the controller (7) of the switching means (4). The first and second signals (20, 18) are continually compared to provide a constant check on the functioning of the transducer (9) and the drive system. The outputs (22) of the transducer (9) in selected frequency bands used for signalling are also monitored by detectors (13) to detect potential interference from harmonic currents. <IMAGE>

Abstract: The front steering linkage (17) is coupled mechanically to the input lever (19) of the rear steering gear (20) by a push-pull cable (18). Steering gear (20) comprises, Fig. 3, links 33, 36 which are equal in length to input lever (19) and which connect lever (19) to a linkage, having links (25, 26, 29) and four pivots (1, 2, 27, 28). which is connected to the rear wheel steering push rod (21). The transmission ratio of gear (20) can be varied by changing the set angle between links (19) and (33). In the straight-ahead condition, pivots (27) and (32) are located one above the other. The steering angle of the rear wheels (13, 14) increases within a predeterminable range on both sides of the straight-ahead position with an increasing steering angle of the front wheels (11, 12). As soon as a limit angle is reached, however, the steering angle of the rear wheels (13, 14) remains substantially constant, even when the steering angle of the front wheels (11, 12) increases further; in this case, if appropriate, the steering angle of the rear wheels can even decrease somewhat. The front and rear wheels may be steering in opposite directions at low vehicle speed and in the same direction at higher speeds. <IMAGE>

Title: Closure with tamper-indicating device
Inventor: STABLES THOMAS FREDERICK
IPC: B65D55/06
Filed: 1991-02-25
Abstract: A closure assembly comprises engagement means including portions 20 which do not deform during application of a cap 7 to a container but which deform during removal of the cap and cause irremediable visible damage to a hologram 28. In the preferred embodiment the cap is screw threaded and encloses a frangible ring 22 which receives the hologram 28. Leg portions 20 project from the ring and engage with a ratchet ring secured to the container mouth. As the cap is unscrewed for the first time, the leg portions cannot readily move with the cap 7 because of their engagement with the ring 6 and the stress set up causes the ring 22 to deform and fracture, so distorting the hologram and indicating tampering. <IMAGE>
Patent GB-2246903-A (GB)
Title: Magnetic disk cartridge
Inventor: SAITO TADASHI
IPC: G11B23/033
Filed: 1991-08-02
Abstract: A magnetic disk cartridge retains a rotational magnetic disk (1) in a case through liners (5) which contact the associated surfaces of the disk and each nave multiple long protrusions (7) formed almost uniformly and almost in parallel to one another on the whole surface of the disk side. As the magnetic disk rotates, the angle of the disk surface contacting the long protrusions can gradually change, thus ensuring removal of dist from the disk. In addition, this structure can reduce the frictional resistance between the liner's surface and magnetic disk, which contributes to faster rotation of the disk. In modifications the protrusions may take other shapes than linear, eg zigzag, sinusoidal or sawtooth, providing the same effect. <IMAGE>

Title: Field emission devices.
Inventor: BIRRELL STUART THOMAS
IPC: H01J1/304
Filed: 1992-01-24
Abstract: In a method of forming a micron-size field emitter, an array of conductive tips (1) with an apex angle less than 90 DEG  is formed on a substrate (3), a layer (7) of dielectric material is formed on the substrate to a thickness substantially equal to the height of the tips, but forming a protuberance (9) over each tip, and then a conductive grid layer (11) is deposited over the dielectric layer, forming corresponding protuberances, followed by a layer (13) of resist material which is of sufficiently low viscosity so that it flows off the protuberances leaving the protuberances substantially unprotected. Finally, the gid layer 13 is etched off the protuberances 9, with the resist 13 acting as a mask, to leave a grid layer aperture surrounded by a collar 12 of grid material and the exposed portions of the dielectric layer are then etched to expose the tips 1 through the apertures 19, 17 in the grid and dielectric layers. The apertures are thereby automatically aligned with the tips without the need for lithographic processes. The process can be adapted, Figs 3a-e (not shown), to provide an arrangement in which two grid layers are formed with aligned apertures over the exposed emitter tips. <IMAGE>
