Title: Axial flow pump/ marine propeller
Inventor: ZHANG WEI-MIN
IPC: H02K7/14
Filed: 1995-08-14
Abstract: An axial flow pump/marine propeller (10; 100; 200; 300; 400) has a pump body carrying a stator (20; 120; 220; 320; 420) which defines a cylindrical inner space, a rotor member (40; 140; 260; 360; 460) being rotatably located in the inner space, and electromagnetic means (24, 26, 44; 124, 126, 144) arranged between the stator and the rotor for generating a rotational magnetic field to drive the rotor to rotate. The rotor has a hollow structure with one or more propelling blades (48; 148; 283; 366) for driving the fluid to flow along the central axis of the pump. This arrangement provides a driving force which produces minimum fluid disturbance and drag therefore a high energy efficiency. The rotor is supported in the pump body by a suspension bearing mechanism which provide rotational and thrust bearing in response to the rotor's rotational and/or axial movements to retain the rotor at a balanced position. In the disclosed embodiments, the bearing means can be formed by mechanical (50; 380; 480), magnetic (150; 190; 240; 250) or hydraulic (49; 149; 270; 356) mechanisms, or a combination of any of them, which keep the rotor fully suspended in and coaxially aligned with the pump body during its operation while at the same time reduce the friction and wear of the rotating parts. By using the magnetic and/or hydraulic suspension to support the rotor, it also avoids the problems and costs of having sealing and lubricating arrangements for the rotary parts, therefore reduce both the manufacturing and maintenance costs. Further arrangements (160, 166) are incorporated into the structure to automatically adjust the axial position of the rotor when it is fully suspended by the hydraulic and/or magnetic mechanisms. Compressible spiral blades can be used to cope with frequent changes of electric inputs and/or output loads. Some of the disclosed embodiments provide clog-free structures suitable for a wide range of applications, such as sewerage pump, sludge pump or marine propeller. An arrangement of two anti-spiral driving members (366, 370; 466, 470) are disclosed for high pressure applications.

Patent GB-2302954-A (GB)
Title: Image sensor array test
Inventor: PRATER JAMES S
IPC: H04N1/00
Filed: 1996-06-28
Abstract: The invention provides for an image sensor array test apparatus and method in which a reset FET (54) is driven with a controllable voltage to set the reverse-bias voltage across a photo-diode (58) at any selectable level of test voltage. In this way each pixel sensor circuit in the array may be tested as if it had received a desired amount of illumination. The drive voltage for the reset transistor (54) can be provided over a column output line (52) when no row access enable signal is applied to the array. In this situation the column line source follower circuit (62, 64) is inhibited by the row access FETs (60). Thus, a separate test voltage can be driven onto the column line (52), through a reset switch (68, 69), and connected through the pixel sensor reset transistor (54) to the pixel sensor photo-diode (58). The variable reset voltage, that is driven onto the column line (52), can be varied between ground and the normal bias voltage V DD for the pixel sensor by use of parallel connected P-channel FET (69) and N-channel FET (68). Alternatively the reset FET (54) could be driven directly by a variable voltage supply (Fig. 2 not shown).

The signals from the photodetector (11-1) to 11-25) are inputted to a lock-in amplifier module (12), where the intensity of the return beam detected by each of the photodetectors and having the same modulation frequency as that of its corresponding input beam is selectively measured. The intensities of beams of light picked up at a plurality of positions are processed by a data processor (16) and the internal information of the living body for a plurality of pickup positions can be obtained without crosstalk.

Title: Retrieval of biosamples
Inventor: SHORTEN GRAHAM JAMES
IPC: B01L3/00
Filed: 1999-05-13
Abstract: A method of retrieving samples of biological material enables retrieval of an individual sample from a frozen array of such samples e.g. in the wells of a microtitre tray. Energy from a laser source of energy is applied to a single storage site within the array. The temperature of said site is monitored and, in dependence thereon, the power input to the laser source or the duration of input is adjusted to melt just the desired sample, leaving those samples surrounding it still frozen. Once the thawed sample is removed from a well, the remaining samples are returned to cold storage without having been disturbed.

Title: Methods of making a cover for an artificial limb and of making an orthosis
Inventor: WATTS ROBERT JOHN
IPC: A61F5/01
Filed: 1999-09-10
Abstract: A cover for an artificial limb is made by forming a skin coloured silicone base layer for overlying the limb, selecting one or more patches 28 of a different tonal colour to that of the base layer, applying the patch(es) to the base layer and blending the periphery of the patch(es) with the base layer so as to provide one or more local colour variations in the colour of the cover and thereby produce an overall appearance similar to that of human skin. Small green or blue strands (30) may be incorporated in the cover to simulate veins and spots (32) may be formed on the surface to resemble hair follicles. Reinforcing portions (36, 38) may be added to reduce creasing in certain areas. A foot orthosis 52 is made by forming a skin coloured sock-like base layer 54 for overlying the foot and applying and blending patches as above so that the overall appearance of the orthosis is similar to that of the patient's skin.

Title: Coupling a mobile 'phone antenna feed to a remote antenna
Inventor: EINAT MOSHE
IPC: H04B1/38
Filed: 1999-10-01
Abstract: A method for coupling electromagnetic radiation from a mobile 'phone to a remote antenna comprises coupling the radiation from the antenna feed 16 of the mobile 'phone to the remote antenna and shielding a major portion of the radiation from the mobile 'phone antenna 17. The shield may be a U-shaped member (Figure 4) or a hollow cylindrical shield (Figure 7) and the coupling to the antenna feed may be via a pin 21 which passes through the mobile 'phone case and which is connected to the external antenna via a matching circuit (51, Figure 5). The method allows a mobile 'phone to be used inside a car having an externally mounted antenna and the shielding of the mobile 'phone antenna ensures good coupling between the mobile 'phone antenna feed and the external antenna by minimising the radiation radiated from the 'phone antenna.
