Title: Transceiver using diffractive optical element to direct beams
Inventor: WU MELINDA W
IPC: H04B10/118
Filed: 2000-11-22
Abstract: A transceiver (10) includes a transmitter (20) for outputting a plurality of beams of electromagnetic energy. The transmitter (20) is a vertical cavity surface emitting laser. A plurality of beams output by the transmitter (20) are directed to the detector (18) by an array of diffractive optical elements (30). In the preferred embodiment, the optical elements are fabricated by imprinting a pattern (34) on a high temperature film substrate (32) using an ultraviolet epoxy. The use of a vertical cavity surface emitting laser allows for high data rates while the diffractive optical arrangement allows for a compact design.

Title: A door lifting device
Inventor: STANSBURY CLIFFORD JOHN
IPC: E04F21/00
Filed: 2001-03-16
Abstract: The lifting device 10 comprises a solid elongate body which is tapered at end T1 for insertion under the bottom edge of a door D to facilitate the correct alignment of the door within the door frame during door installation. The lifting device 10 has a parallelogram shaped side-section demonstrating rotational symmetry(see Fig 3), with two tapered ends T1 and T2 enabling the device to act as a primary mechanical lever when downward pressure is applied to end T2. The device turns on its fulcrum, simultaneously lifting the door. Due to its rotational symmetry the device can be turned over and around to achieve the same effect. In order to retain stability and limit the risk of it toppling over, the device is greater in width than thickness.

Title: Energy degrader or moderator with focus means for a particle beam
Inventor: FARLEY FRANCIS JAMES MACDONALD
IPC: G21K1/10
Filed: 2002-01-28
Abstract: An energy degrader for particle beams comprising two or more slabs of matter through which the beam passes in succession with focusing means before the first slab and between the slabs to concentrate the beam successively onto the centre of each slab. The slabs may be made of diamond, boron carbide, beryllium or graphite, and the beam is focused and refocused by quadrupole triplets to a small spot at the centre of each slab. By dividing the degrader in this way into several separate slabs with refocusing lenses between the slabs the increase of beam emittance due to lateral scattering is minimized.

Title: Blade clearance control for turbomachinery
Inventor: RESS JR ROBERT A
IPC: F01D11/22
Filed: 2000-07-28
Abstract: A system includes a gas turbine engine (30) having a shroud (130) and a rotor (120) with one or more blades (126, 127).

Title: Apparatus and method for the disposal of drilling solids during drilling of subsea oilfield wellbores
Inventor: FINCHER ROGER W
IPC: E21B21/06
Filed: 2000-09-14
Abstract: The system may include a separator (130) at the sea floor adjacent the wellhead, which separates solids above a predetermined size from the wellstream. The wellstream then enters one or more underwater pumps (144), which pump the wellstream to the surface. A crusher (136), as a separate unit, integrated in the separator or in the pump, receives the separated solids and reduces them to relatively small-sized particles. The small particles are then pumped or moved to the surface by the pumps utilized for pumping the wellstream to the surface or by a separate underwater pump. Alternatively, the separated solids are collected from the separator into a container, which container is then transported to the surface by a suitable method. Solids reaching the surface are removed to obtain filtered fluid, which after conditioning by conventional methods is pumped back into the wellbore as the drilling fluid.

Title: Audio presentation of text messages
Inventor: BELROSE GUILLAUME
IPC: G09B21/00
Filed: 2002-05-13
Abstract: A text message, e.g. a message sent using a short message service (SMS) of a mobile network, is converted into audio form for delivery to a target recipient. A text-to-speech (TTS) converter converts the message into speech. To enable the text message to be presented in a personalised manner, e.g. with an appropriate voice, emotion, mood, etc., tags identifying stored user-related recordings can be included in the text. For example, the message can include: voicing tags identifying particular voice types, background tags for adding background sounds, sound effect tags for adding sound effects and substitution tags for inserting pre-recorded passages provided by the message sender. The recordings associated with the tags included in the message are retrieved and used together with the output of the text-to-speech converter to produce an audio output of the text message. Tags may comprise codes, emoticons ("smileys") or text strings, e.g. "cul8r" ("see you later"), "hbtu" ("Happy Birthday to you"). Conversion applicable to SMS, email, multi-media or instant messaging systems. The message sender or recipient may control the mapping of the tags to the recordings, e.g. via WAP/web enabled user interface over the internet. Messages can be delivered to voicemail and adapted for delivery to answerphones. A recipient may be given the option of receiving the audio version of a text message only if desired.
