Title: Improvements relating to bicycles
Inventor: WIGLEY VICTOR JOSEPH
IPC: B62L5/00
Filed: 2000-05-31
Abstract: A bicycle has a crank with variable length arms such the throw of the crank may be varied whilst the bicycle is in use. To this end, the crank comprises a hollow arm (a) in which is telescopically mounted an extension (b). A spring (c) biases the extension outwardly of the crank. A protruding nib (e) can engage any one of a multiplicity of notches (f) to define pre-determined crank lengths. A spring (d) biases the extension (b) in a manner to maintain the nib (e) in its selected notch (f). In order to vary the length of the crank sideway pressure is applied to the pedal (h) and the extension is either pushed inwardly or is allowed to move outwardly under the influence of the spring (c). Other improvements disclosed include a novel handlebar design allowing the hand and upper forearm to control steering, a brake operated by reverse pedal rotation, and a cover to protect the wheels from accidental contact with, e.g. a polo stick. The invention may optionally be embodied as a penny-farthing design.

Title: Electro-hydraulically controlled tractor
Inventor: BEAUFORT RONALD E
IPC: E21B23/00
Filed: 1999-12-17
Abstract: A tractor (20) for moving within a borehole comprises body and two propulsion assemblies (24, 26) that are longitudinally movably engaged with the body. The tractor body has annular pistons (34, 36, 38, 40) configured to receive hydraulic thrust to propel the body longitudinally. Each propulsion assembly includes a gripper (42, 52) and propulsion cylinders (44, 46, 48, 50). The gripper has an actuated position in which the gripper limits relative movement between the gripper and the inner surface of the borehole, and a retracted position in which the gripper permits free relative movement between the gripper and the inner surface of a borehole. Each propulsion cylinder contains one of the pistons. The tractor includes a control assembly (30) having valves and hydraulic circuitry which control the sequencing of fluid distribution to the propulsion cylinders, and of the actuation and retraction of the grippers. A throttle valve (54) controls the fluid flowrate to the pistons.

IPC: G06F3/033
Filed: 2000-09-06
Abstract: A wireless rotating signal transducer. A control circuit is provided for transferring power and communication signals through a wireless coupling device (56) in a vehicle steering column. A squib firing circuit (62) transforms a high energy power signal suitable for firing an air-bag (46) from the column side to the wheel side. A low energy power circuit (54) generates a signal from the column side to the wheel side suitable for operating isolated wheel side electronics, such as cruise control, and the like. A pulse-encoder circuit (104) communicates low-level control signals suitable for signalling wheel-side commands from the wheel side to the column side. The low energy power circuit (54) and pulse circuit (104) operate simultaneously and continuously without signal debilitating interaction.

Inventor: MITAMA MASATAKA
IPC: H04W92/08
Filed: 2001-02-01
Abstract: A portable radio communication apparatus includes a main body and a sub-apparatus. The main body communicates with a partner. The sub-apparatus is mechanically separated from the main body. The main body and the sub-apparatus communicate with each other wirelessly. The sub-apparatus includes a call signal arrival display unit and a response unit. When the main body gets a call signal from the partner, the main body transmits a call arrival signal to the sub-apparatus. The main body transmits a response message to the partner in response to a response signal. The call signal arrival display unit sends a notice that the main body gets the call signal in response to the call arrival signal. The response unit outputs the response signal to the main body in response to an operation performed on the response unit.

IPC: E21B43/38
Filed: 2001-09-13
Abstract: In a production fluid handling method, gas and liquid components of a fluid produced from an underground formation 12 are separated downhole, the separated gas 20 either being reinjected into the formation or recovered to the surface. Preferably, the method includes the further step of separating the liquid components of the produced fluid to obtain oil 18 and water 16, at least a proportion of the water 16 advantageously being either reinjected into the formation or recovered to the surface. In a preferred form, the components of the produced fluid are separated using horizontal gravity separation.

Title: Copper alloy interconnection layer
Inventor: AOKI HIDEMITSU
IPC: H01L21/768
Filed: 2002-02-18
Abstract: In a damascene method trenches in interlayer insulation 12 are filled with a barrier layer (14), a seed layer (15) and a copper containing layer 17. The surface of the copper layer 17 is kept free of copper oxide by an anti-corrosive (22) treatment (eg benzotriazole, uric acid), or by not exposing the device to an oxygen atmosphere. Alternatively copper oxide which does form is removed using a cleaning agent (eg carboxylic acid, oxalic acid). The oxide-free surface of the copper is subject to a N<SB>2</SB>/ NH<SB>3</SB> plasma treatment to form a copper nitride layer 24. A silicon containing copper diffusion prevention layer 18 (eg SiN, SiON, SiC, SiCOH) is formed by plama CVD. The CuN layer 24 suppresses diffusion of silicon into the copper layer 17 such that the thickness of copper silicide layer 25 is reduced. Interconnection resistance is thus reduced.

Title: Adhesive cement
Inventor: BENNETTS ALAN J
IPC: A61K6/083
Filed: 2002-03-08
Abstract: An adhesive cement is prepared by coating an aluminosilicate glass ionomer with an acid polymerization inhibitor of pKa between 2-3.5, and then mixing the treated glass with cyanoacrylate monomer and water. The glass is treated by dissolving the acid, typically tartaric, tartronic, malic, maleic or mellitic acid in methanol and adding the glass powder to form a slurry, then evaporating the methanol. In a further embodiment, the water can also contain a polyacid compound such as polyacrylic acid, polyvinyl phosphonic acid, a coploymer of acrylicacid with itaconic acid and/or vinylphosphonic acid, or mellitic, phytic or tannic acid. In use the cyanoacrylate polymerizes to from a binding resin, whilst the ionomer undergoes an acid-base reaction to form a compound which forms a strong adhesive bond with materials such as metals, glasses, vinyl polymers, or dental material.

Title: Exposing photosensitive material with a scanning head
Inventor: ZELENKA THOMAS
IPC: G03F7/20
Filed: 2002-03-13
Abstract: In a method and an apparatus for exposing photosensitive material (8), in particular for exposing a printing form, a surface of the photosensitive material (8) is scanned by at least one light beam (28, 50), which is emitted by a light source (22, 40), Before striking the photosensitive material (8), the beam is modulated, interrupted and/or deflected. An exposure head (14) is moved at a constant distance from the surface in relation to the latter and to the light source (22, 40) in order to scan the surface of the photosensitive material (8) with the light beam (28, 40). After it has emerged from the light source (22, 40) substantially parallel to the surface to be exposed, the light beam (28, 40) should be deflected through a gaseous medium toward the exposure head (8) and there should be reflected onto the surface. The gaseous medium may be air.

Title: Introducing EGR gas into i.c. engine inlet manifold
Inventor: KLAS JEFFREY
IPC: F02M25/07
Filed: 2002-06-01
Abstract: Various locations are disclosed for introducing EGR gas into the intake manifold, eg a double-plenum intake manifold for an inline six-cylinder engine. The EGR inlets 15 may be located at or near the intersections between the primary runners 14 and the plena 13, fig. 1. In a second embodiment, the EGR inlets may be provided in an aerodynamically curved flange 20, fig.3, located inside the secondary runners 11 and whose convex side faces the intake air inlet 12. In a third embodiment, the expansion of intake air from each plenum 13 into a mixing chamber (30, fig.5) creates a region of low pressure into which EGR gas is injected at an inlet (15). In a fourth embodiment, each secondary runner 11 contains a flow strut (40, fig.6) having a tear-shaped cross-section and containing the EGR inlet(s). In the first, third and fourth embodiments, it is advantageous that the EGR gas is introduced away from the air inlet because sensitive electronics may be located near the air inlet for cooling purposes.
