Title: Electric motor apparatus
Inventor: BARBA VALENTIN
IPC: F16D65/14
Filed: 1996-10-24
Abstract: The apparatus has circuitry 150, 160 for switching a permanent magnet motor 170 and dynamic braking the motor, such as via a short circuit 135, and an electromagnetically operated positive locking device (220, 215 Fig 4) in order to prevent the motor from rotating after power has been removed. In another aspect the positive locking device (Figs 4-6) has a plate (220) mounted on the motor which engages a disk or hub (210, 215) on the shaft of the motor. In another aspect the positive locking device (Figs 7-9) has a pin (327) engaging one of holes (313) on a disk or hub (310) attached to the motor shaft. A further aspect relates to rotating the motor in either of two directions and for dynamic braking. The electromagnetic coil of the locking device may be connected in parallel (Figs 10A, 10B) or series (Figs 11A, 11B) to the motor. Further aspects relate to a dynamic braking circuit for a dual armature (472, 478 Figs 12-14) permanent magnet motor and to the dual armature motor. By applying current to one or the other of two oppositely wound armature coils the motor is made to rotate in either direction. When power is removed from the active armature, this armature is short circuited through a diode (457) which provides dynamic braking. The positive locking device may be used with aircraft accessories.

Title: Angular rotation rate detector
Inventor: KOBAYASHI TOSHIHIRO
IPC: G01C19/5677
Filed: 1997-03-13
Abstract: An angular velocity detector has first and second detecting electrodes 6a, 7a , symmetrically disposed with respect to a direction of excitation D2 of a piezoelectric oscillator 2 and adjacent to nodes of a first oscillation produced by the excitation. When the oscillator rotates, the detecting electrodes detect a second oscillation produced by the Coriolis force. A signal detected by electrode 6a will be lagging or leading in phase with respect to a signal detected by electrode 7a. An electrical circuit produces an angular rate signal which represents the phase difference between the two signals. Modifications are shown to improve the accuracy of detecting low angular velocities. In a first embodiment, electrodes 6a, 7a are offset by angle * small Greek theta * from nodes of the first oscillation. In other embodiments, the resonant frequencies of the first and second oscillations are made to be different, by giving the vibration and detection system different impedances (figs. 10), or providing the oscillator with weights Q (fig. 19) or notches R (fig. 22).

Title: Hyperlinked index entries have adjustable text according to context
Inventor: HEALEY MARTIN JAMES RONAN
IPC: G06F17/30
Filed: 1997-08-13
Abstract: Forming a hyperlinked index of computer-readable pages of information, e.g. for sales purposes. The index comprises hypertext linked items 11-14, each item containing a hypertext linked list of associated items, e.g. 111, 112. Each item is stored as entry 21 in a table, each table entry having long-name field 211, short-name field 212, synonym field 213, URL field 214 and related items field 215. The index is created by accessing the table entries: for each entry, the terms in fields 211 and 213 are displayed as main items 11,12 in the index, whereas each associated item in the list, e.g. 131, displays the text appearing in the short-name field 212 of the table entry for the item referred to in the related-items field 215 of the main entry. By thus reducing the amount of anchor tag text appearing in the associated lists in the index, the screen space used is reduced, whilst the use of synonyms in independent index entries facilitates searching.

Title: Forming a layer on a pre-stressed semiconductor wafer
Inventor: DOBSON CHRISTOPHER DAVID
IPC: H01L21/02
Filed: 1997-09-04
Abstract: A method of forming a layer 15 on a semiconductor wafer 13 comprises applying tensile stress to the wafer, depositing the layer on the wafer, and releasing the wafers from the stressed condition. A seed layer 14 is deposited on the wafer before the wafer is stressed by means of an electrostatic chuck 10 with a convex surface 11. The layer 15 is then deposited on the wafer and allowed to harden or set. On release from the chuck, the wafer flattens to compress the layer 15 and prevent the formation of cracks.

Title: A dowel interference connection of tunnel linings or pipeline segments
Inventor: GIMBERT ALAN WILLIAM
IPC: E21D11/08
Filed: 1998-01-09
Abstract: A connection comprises a pair of concrete tunnel linings or pipeline segments (10,11, Fig 1), each with sleeves 25 provided in the abutting edges of the concrete segments (10,11). Captive within each sleeve 25 is an interference element 32 (see Fig 3) which co-operates with the nose 21 at one end of a dowel (26, Fig 1) which is inserted into the first segment (10). On bringing the edges for abutment together, the other end of the dowel (26) engages the other sleeve 25 in the other segment (11) and co-operates with the respective interference element 32 to lock the segments (10,11) together. In a further embodiment (see Fig 3), axial slits (43) at the ends of a dolly (26) co-operate with projecting elements (42) to expand the dolly ends (26) into receiving members (23), creating an interference connection which holds the segments (10,11) together.
Patent GB-2319048-A (GB)
Title: Locking system
Inventor: MCLEOD GAVIN THOMAS
IPC: E21B23/02
Filed: 1996-08-27
Abstract: Locking system (196) is provided for selectively locking an external sleeve (76) to a main body (74) of a downhole tool (14). Locking system (196) comprises a pair of opposed holes (198) formed in the main body (74). The holes (198) capture respective locking balls (200). A channel (210) extends from each hole (198) longitudinally about the outer surface of the main body (74). A spring (206) held within the main body (74) acts to push the balls (200) out of holes (198). Openings (212) are also formed in the sleeve (76) and disposed so that the balls (200) can protrude therethrough and contact the inner circumferential surface (28) of a drive sub (12) by virtue of the bias of spring (206). When the internal diameter of the drive sub (12) is relatively small, the balls (200) are pushed inwardly against the spring (206) and reside, at least partially, within holes (198). This prevents the balls from moving longitudinally about channels (210) thereby locking the sleeve (76) to the main body (74). However, when the internal diameter of the drive sub increases, the balls (200) are pushed radially outwardly by the spring (206) to the extent that they can then escape holes (198) and roll along channels (210). This allows the sleeve (76) to slide relative to the body (74).
