Title: A downhole device eg a centraliser
Inventor: WHITELAW HARRY
IPC: E21B19/24
Filed: 2003-01-30
Abstract: A downhole device (10) is applicable as a casing centraliser to support the casing away from the well bore wall. It comprises an annular body (12a, 12b) formed of a polymer based material and a sheath (14), which is made from a metallic material. The polymeric nature of the annular body (12a, 12b) provides improved torque resistance and low friction characteristics to the device, and the sheath (14) provides increased structural strength to the device and reduces tendency to swage. The annular body may be moulded around the sheath, or the sheath moulded around the annular body. The annular body may be formed by two or more parts that are clipped together. Alternatively, two parts of the body may be hinged together. The sheath would then be similarly hinged. The blades 16 may be hollow and have openings therein to allow fluid to flow therethrough.

Title: Laser source using very high relative feedback and method for making such a laser source
Inventor: MATUSCHEK NICOLAI
IPC: H01S5/065
Filed: 2003-02-13
Abstract: The invention relates to the stabilization of high power semiconductor laser diode sources as they are extensively used in the field of optical communication. Such lasers are mostly employed as so-called pump laser sources for fiber amplifiers, e.g. erbium-doped fiber amplifiers, and are designed to provide a narrow-bandwidth optical radiation with a stable power output in a given frequency band. To improve the wavelength locking range of such laser sources when operating without an active temperature stabilizing element, an external reflector 9 providing very high relative feedback is used. The reflectivity bandwidth of the external reflector is broadened for improving the stability of the laser source. In commonly employed optical fibers for conducting the laser beam, the external reflector is formed by one or a plurality of appropriately designed fiber Bragg gratings.

Title: Tractor with improved valve system
Inventor: BLOOM DUANE
IPC: E21B23/00
Filed: 2001-12-03
Abstract: A hydraulically powered tractor includes an elongated body, two gripper assemblies, at least one pair of aft and forward propulsion cylinders and pistons, and a valve system. The valve system comprises an inlet control valve, a two-position propulsion control valve, a two-position gripper control valve, two cycle valves, and two pressure reduction valves. The inlet control valve spool includes a hydraulically controlled deactivation cam that locks the valve in a closed position, rendering the tractor non-operational. The propulsion control valve is piloted on both ends by fluid pressure in the gripper assemblies. The propulsion control valve controls the distribution of operating fluid to and from the propulsion cylinders, such that one cylinder performs a power stroke while the other cylinder performs a reset stroke. Each end of the gripper control valve is piloted by a source of high-pressure fluid selectively admitted by one of the cycle valves. The gripper control valve controls the distribution of operating fluid to and from the gripper assemblies. The cycle valves are spring-biased and piloted by fluid pressure in the propulsion cylinders, so that the gripper control valve shifts only after the cylinders complete their strokes. The pressure reduction valves limit the pressure within the gripper assemblies. These valves are spring-biased and piloted by the pressure of fluid flowing into the gripper assemblies. Some or all of the valves include centering grooves on the landings of the spools, which reduce leakage and produce more efficient operation. The propulsion control and gripper control valves include spring-assisted detents to prevent inadvertent shifting.

Title: An expansion bolt
Inventor: HUANG PAN-CHING
IPC: F16B13/06
Filed: 2004-03-27
Abstract: An expansion bolt comprises a bolt 31, an expanding sleeve 32, and a conical nut 33. The expanding sleeve comprises expanding sections 324 325, an end section 321 and a stop 323. Expansion of the sleeve is caused by compression due to movement of the conical nut along the bolt. The stop 323 limits the movement of the nut relative to the sleeve and enables complete radial expansion to be achieved. The stop is a strip section formed integrally of the sleeve which is bent inwards by stamping. The end section 321 of the sleeve has a slot 322.
Patent GB-2413241-A (GB)
Title: Dynamic allocation of resources based on a short term urgency indication
Inventor: HULBERT ANTHONY PETER
IPC: H04L12/56
Filed: 2004-04-14
Abstract: A method of scheduling at a base station of a communication system comprises sending a short term urgency indication (1) from a terminal (10) to the base station (11), which base station is adapted to dynamically allocate resources between terminals. The base station varies priority for resource allocation from the terminal according to the short term urgency indication received and the terminal provides the urgency indication by dynamic physical layer signalling on a common, shared or dedicated physical channel. This allows a scheduler in the base station to maintain a quality of service (Qos) target by additional signalling indicating how urgently the terminal wishes to transmit its data, so that the scheduler can increase the priority of a terminal for a specific transmission period without allocating a higher priority channel on a permanent basis.

Filed: 2004-12-08
Abstract: An instrument holder (10) for surgical use has a remote locking mechanism (12) and is elongated having a proximal end (14) and a distal end (16). The holder (10) has an elongated shank (20), a ring (22), a locking component (28) and a spring (32). The elongated shank (20) is equipped, at the distal end (16), with a head (26) adapted to receive an instrument (24). The locking component (28) is substantially cylindrical, elongated and is biased in a first direction (30) toward the head (26) by a spring (32). The locking component (28) includes structures (34) capable of locking the instrument (24) onto the distal end (16). The ring (22) is biased by the spring (32) in a second direction (36) against the locking component (28) towards the proximal end (14) constrained to slide longitudinally on the shank (20), at the proximal end. The remote locking mechanism (12) permits releasable connection to the shank (20) and is engaged by rotation of the ring (22) such that release of the ring from the shank allows the spring (32) and locking component (28) to slide freely off the shank in order to permit cleaning of the instrument holder.

Title: Filtering images according to coating applied upon printing
Inventor: JACOB STEVE A
IPC: G06T5/00
Filed: 2004-12-22
Abstract: A printer comprises a program to apply a filter profile associated with a filtering material - for example, a coating to be applied to a printed image - to adjust an image to be printed. Thus, the printing device digitally adjusts an image before it is printed so that, when a coating or adhesive is added the resulting printed image, the image is already processed to compensate for optical effects caused by the applied coating or layer. Referring to Figures 4A - 4D, a high pass software filter is applied to sharpen (Figure 4B) the original image 434 such that, when a polyester, protective film layer 438 is applied (Figure 4C), the resulting image appears as intended; that is, the image covering material 438 acts as a low pass filter, smoothing the previously sharpened image. To determine the filter function to be applied to the image before printing, the filter profile of the coating or laminate material (Figure 5) may be determined first, by scanning a material sample; a Fourier transform process can then be used to derive the corresponding image filter profile (Figure 6).
