Patent GB-2256713-A (GB)
Title: Eddy current flaw size detecting probe
Inventor: LUND FRANK PHILIP
IPC: G01N27/90
Filed: 1991-08-30
Abstract: The probe, for generating a signal indicative of a quantitative measurement of the size of a surface defect, comprises a magnetic field generator 10 for inducing currents in the surface and a perturbation current sensor arrangement 20, 40 positioned relative to the field to give an output providing said quantitative measure. The probe comprises a solid cylindrical former 50 on which is wound the perturbation current sensing coils which are rectangular 20a or figure of eight shaped 40a and have axes radial to the former. The field generator coil 10 has an axis aligned with the axis of the former and is constructed to produce a magnetic field which produces a spatially varied magnetic field in a material under test. <IMAGE>
Patent GB-2247942-A (GB)
Title: Cryostats
Inventor: OOTA HISASI
IPC: F25D19/00
Filed: 1991-09-04
Abstract: In a cryostat comprising a cryogen container 2 for containing a liquid cryogen, and a refrigerator 6 for recondensing cryogen gas resulting from evaporation of the liquid cryogen, the pressure 11 within the cryogen container is detected, and when the pressure falls to a negative value due to excessive cooling, a heater 12 is turned on to raise the temperature thereby to enhance the evaporation. As an alternative, the refrigerator 6 may be turned off or its power may be lowered. This will increase the pressure within the cryogen container. When the pressure rises to a positive value, the heater is turned off or the refrigerator is turned on or its power is raised. Through such control the pressure can be maintained at a constant, positive value. As a result, deformation of the cryogen container due to pressure variation is avoided, and deformation of the superconducting coil 10 wound on the cryogen container is avoided, and the magnetic field strength and the magnetic field uniformity can be maintained constant. <IMAGE>

Title: Optical welding filter window
Inventor: DICK GORDON JAMES
IPC: A61F9/06
Filed: 1991-09-05
Abstract: An optical welding filter window, has a green tinted glass sheet 1, bearing an outer layer of optically dense filter material 2, and an inner layer of optically dense filter material 3. The inner filter layer 3 and outer filter layer 2, may have a pattern of lines and gaps such that light will pass between the gaps only at a pre-determined set of angles. Only the lower area of the window is covered by those lines and gaps, on both surfaces, the upper portion being covered on the outside only by an uninterrupted rectangle of the optically dense filter material, to provide full ultraviolet protection over its entire area. The gaps between the lines on the lower part of the filter window must be smaller than the width of the lines themselves. The complete filter window provides full ultraviolet protection during welding, whilst allowing the user to view the work area prior to and after welding. Secondary stray ultraviolet light, reflecting off other objects, is filtered by the green tinted glass, while the horizontal spaces admit only one third of the reflected secondary light, thus reducing this glare still further. <IMAGE>

Title: Tuned i.c. engine intake and exhaust systems
Inventor: HALL KEITH GORDON
IPC: F02B27/02
Filed: 1991-09-26
Abstract: In a system having respective cylinder pipes leading to a common junction the pipes are of substantially of equal diameter with equality of flow division at the pipe junctions and variation of effective pipe length is achieved by opening valves 6 and 15 or by progressive movement of a pipe dividing wall (45, Fig. 5). A discontinuity (34, Fig. 4) in the pipe cross- section may also affect the effective pipe length due to flow separation at higher flow rates. The pipes may be arranged in compact serpentine form (Fig. 6).   <IMAGE>

Title: A pnematic pressure pulse generator for testing blood pressure monitors
Inventor: SCOTT LESLIE ARTHUR
IPC: H04R9/02
Filed: 1993-03-25
Abstract: A pneumatic pressure pulse generator comprises a main chamber having two compartments separated by a diaphragm 14 which is displacable by a audio drive unit 2 and 11, and a smaller chamber connected to one compartment 18 of the main chamber. An electrical pulse signal applied to the drive unit produces a positive pressure pulse in compartment 18 which passes through a port 25 to an outlet 16 to simulate an adult's pulse. A flow restrictor 3 prevents corresponding negative pulse in the other compartment passing through a port 21 to the outlet 16, while equalising the static pressure in the compartments. A smaller pressure pulse to simulate a neonate's pulse is produced at an outlet 17 via a diaphragm 13 in the smaller chamber. The pulse may be applied directly to the blood pressure monitor or to a cylinder about which the cuff of the monitor is wrapped. <IMAGE>

Title: A tape database control process
Inventor: WALSH JOHN
IPC: G11B27/11
Filed: 1994-01-11
Abstract: A tape database controller operates in conjunction with a tape controller of a tape system to allow not only batch archival and batch retrieval of data, but also on-line access to data as if the database were stored on disk. Each database is broken down into a number of datasets and a single tape volume (31) is assigned to each dataset. Data blocks (36) in each tape volume include a number of records (37) each comprising a variable number of sub-records (41) and a single header (40). An index file (Fig. 4) includes an index entry record for each primary key, this record having a number of cycles, there being one cycle for each data record (37). Therefore, by using a primary key and a storage date, the database controller 10 may determine the identifier for the tape volume (31) and of the data block (36), the particular data record (37) being retrieved by use of the primary key. The primary key is stored in a field (51) of the header (40). <IMAGE>

IPC: A61F2/64
Filed: 1994-11-11
Abstract: A polycentric knee mechanism for a lower limb prosthesis has an upper thigh member 1 and a lower shin member 2 joined by a plurality of links 25, 26 (not shown), 30, 31, said links and members defining a four-bar linkage. The locus of the centre of rotation of the mechanism when the lower member 2 is rotated with respect to the upper member 1 is a downward curve which, over the initial range of flexion of the mechanism, is convex in the posterior direction. The centre of rotation remains to the posterior of the mechanism over the initial range of flexion, thereby providing knee stability. Also two variations are described; the first comprising a four-bar linkage has a posterior centre of rotation over the initial range of flexion. The second variation has pivotal connections with the upper member below pivotal connections with the lower member at full extension. <IMAGE>

Title: Communication with a mobile station in an unknown spot beam
Inventor: FEBVRE PAUL
IPC: H04B7/15
Filed: 1995-07-28
Abstract: A mobile terminal 6 communicates via a satellite 8, which projects a number of overlapping spot beams 10, with a fixed earth station 2. To determine which spot beam 10 is to be used for communication, the mobile terminal transmits signals in a common signalling channel which is simultaneously received by all, or a subgroup of, the spot beams 10. The satellite 8 retransmits to the fixed earth station 2 in separate channels the signal as received by each of the spot beams 10 which are able to receive the common signalling channel. The relative strengths of the signal as received in the different spot beams 10 are compared at the fixed earth station and a communications channel is assigned to the mobile terminal in one of the spot beams 10, selected according to the comparison of signal strengths or number of communications channels available in each spot beam. The spot beams may be grouped, adjacent beams not sharing frequencies. A terrestrial cellular system is also disclosed, operating on the same method.
