Title: Borehole surveying
Inventor: SHIELLS GORDON MALCOLM
IPC: E21B47/022
Filed: 1996-09-10
Abstract: A borehole survey is conducted at a drilling site S by a so-called Interpolated In-Field Referencing (IIFR) method in which: (a) absolute local geomagnetic field data is obtained by spot measurement of the earth's magnetic field at a local measurement site R which is sufficiently close to the drilling site S that the data is indicative of the earth's magnetic field at the drilling site but which is sufficiently remote from the drilling site that the data is unaffected by magnetic interference from the drilling site and other man-made installations; (b) time-varying geomagnetic field data is obtained by combining the absolute local geomagnetic field data with data indicative of variation of the geomagnetic field with respect to time obtained by monitoring variation of the earth's magnetic field with respect to time at one or more remote monitoring sites P1, P2; (c) downhole magnetic field data is obtained by monitoring by means of a surveying instrument the magnetic field in the vicinity of the borehole at a series of locations along the borehole; and (d) the orientation of the borehole is determined from the downhole magnetic field data and the time-varying geomagnetic field data. Such a survey method takes into account short-term variations in the geomagnetic field caused by electrical currents in the ionosphere and is therefore more accurate than known survey methods.

Title: Method for inspecting process defects occurring in semiconductor devices
Inventor: BAE SANG MAN
IPC: G03F7/20
Filed: 1996-10-02
Abstract: A method for inspecting process defects occurring in a semiconductor device comprises forming positive and negative-type etchable layer patterns (2A, 2B) on a semiconductor wafer (1) by use of positive photoresist film patterns (12) and negative photoresist film patterns formed respectively on adjacent dies. The difference in dimension between corresponding patterns on adjacent dies is detected in a die-to-die comparison manner by a defect inspection device. The light exposure mask used in the pattern formation is compensated for based on the result of the detection, thereby reducing the difference in critical dimension of patterns in each field of the light exposure mask due to the proximity effect, the topology of the wafer, the difference in thickness of thin films on the wafer, and the aberration of the lens as used. The positive-type etchable layer patterns (2A) are arranged on every second die of the semiconductor wafer whereas the negative-type etchable layer patterns (2B) are arranged on dies of the semiconductor wafer adjacent to the dies on which the positive-type etchable layer patterns are arranged.

Patent GB-2307744-A (GB)
Title: Pressure sensor
Inventor: STANSFELD JAMES WOLRYCHE
IPC: G01L9/00
Filed: 1996-11-29
Abstract: A pressure sensor device 10 comprises three layers 11a, 12 and 11b of silicon, fusion-bonded together. The outer layers 11a and 11b form a sealed housing around the central layer 12 to which they are bonded, and in use a cavity 13 between the housing 11a, 11b and central layer 12 is evacuated. The sensor device 10 is normally placed inside a component for containment of a pressurised fluid (not shown). Due to the cross-sectional shape of the device 10, pressure exerted by the fluid causes the layers 11a and 11b to flex inwardly in the region of minimum cross-sectional dimension and thereby outwardly in the region of maximum cross-sectional dimension, thereby placing under tension a balanced twin beam vibratable element 16 on the central layer 12. The tension across the vibratable element affects its resonant frequency of vibration. Accordingly by accurately measuring the resonant frequency of vibration of the element, and by comparing this to previous calibration data, the magnitude of the pressure exerted on the layers 11a and 11b may be determined. The device may be made in other materials such as quartz and/or include temperature compensation facilities.

Patent GB-2329141-A (GB)
Title: Continuous casting
Inventor: WINDER EDDIE
IPC: B22D11/04
Filed: 1998-09-07
Abstract: The invention aims to accommodate a variety of methods for allowing deviations relative to the theoretical passline with minimal strain rates and stresses, thereby providing a high quality product. A casting apparatus and a method of casting is thus provided in which any deviations of the cast strand away from or towards the theoretical passline or any deviations to the edges of the cast strand are defined, at least in part, by continuous curves. One example of such a suitable continuous curve is a clothoid which applies a uniform rate of curvature removal or application along its length, therefore, leading to the lowest possible strain rates being applied to the solidifying shell over this length. Increased equipment life, reduced withdraw resistance and wear and improved product quality result as benefits of this techniques application.

Title: Modelling solar radiation pressure on satellites
Inventor: ZIEBART MAREK KENNETH
IPC: B64G1/24
Filed: 1999-09-13
Abstract: The effect of Solar Radiation Pressure (SRP), caused by sunlight incident on a satellite or spacecraft 10 can be investigated by determining precisely which surface areas of the satellite or spacecraft, incident sunlight falls. The shape of the vehicle 10 is represented by a plurality of planar shapes, and the incident flux as a plurality of rays, the intersection point of each ray with each of the planar shapes being calculated (Figs. 3 and 4). The intersection points closest to the source are determined, defining the area or areas of the body on which the flux is incident. On the basis of these data, and variations of the sunlight incidence angle and optical properties of the vehicle 10, corrections can be made for effect of the SRP on the position or motion of an orbiting vehicle. Apparatus may then be provided for determining the position of a user based on signals received from earth orbiting navigation satellites (for example the GPS or GLONASS constellations), where the satellite positions are predicted accounting for the effect of SRP according to the described method.
Patent GB-2349826-A (GB)
Title: Speculum
Inventor: GEORGE SAMUEL
IPC: A61B1/32
Filed: 1999-12-06
Abstract: A speculum comprises a first blade (4), within which are optionally mounted a pair of side blades (37, Fig 8 not shown), associated with a forward operating lever (6) and a second blade (3) associated with a rearward operating lever (7) that is connected by a pivot (2) to the forward operating. The pivot is a floating pivot permitting relative translational movement between the operating levers. The operating levers are also preferably connected by a ramp (29) and a ramp follower (30), the ramp being opposed to the pivot so that the pivotally-connected operating levers and the ramp define a triangle. During relative pivotal movement of the operating levers towards one another, the ramp follower moves up the ramp towards the pivot, this movement of the ramp follower up the ramp causing translational movement at the floating pivot that widens the proximal aperture between the blades. In addition, the side blades can be employed selectively to improve visual and physical access to the cavity in which the speculum is used.

Title: Mobile station providing sequential dialling using stored list
Inventor: HUMES MICHAEL
IPC: H04M1/2749
Filed: 1999-12-24
Abstract: Telecommunication device and method enabling sequential dialling of a plurality of linked directory numbers, the invention being particularly useful when originating calls to try to contact a subscriber associated with a plurality of different communication devices, e.g. home phone, office phone, mobile phone, pager, voicemail. A number of associated directory numbers are sequentially correlated into a link list and stored within a telecommunications device, such as a mobile station. When a first call connection is originated using a first number determined to be one of the stored directory numbers, in response to detection of a predetermined event, such as a user instruction, call connection failure, call busy or number unobtainable, a second call connection is originated using a second number retrieved from the associated link list, the second number being the next number in the list. Thus in response to the detected event, the mobile sequentially and individually retrieves the linked directory numbers and automatically originates outgoing call connections without the user having to separately and inconveniently enter the associated directory numbers.
