Patent GB-2368184-A (GB)
Title: Magnetron including decoupling plate
Inventor: SALEEM KESAR
IPC: H01J23/48
Filed: 2000-03-30
Abstract: A magnetron includes a decoupling plate 16 located between the end hat 15 of the magnetron cathode 21 and an output coupling member 11. The use of the decoupling plate 16 presents a high impedance and gives a resonant circuit which is arranged to be resonant at the operating frequency of the magnetron. This prevents or reduces power loss due to capacitive coupling. In another arrangement, the decoupling plate is mounted by a post on the end hat of the magnetron cathode. The magnetron may be operative at X band. The plate 16 may be made of copper.

Abstract: A camera (101) includes a built-in flash (111) and a controller (11) for controlling the camera. The controller includes different photographic modes; an auto-exposure-mode selecting mode in which an appropriate photographic mode is automatically selected from the different photographic modes based on photographic conditions, the controller allowing the built-in flash to discharge automatically in the selected appropriate photographic mode when the built-in flash discharges at a most appropriate time of exposure; and a flash-prohibiting/auto-exposure-mode selecting mode in which an appropriate photographic mode is automatically selected from the different photographic modes based on photographic conditions, the controller prohibiting the built-in flash from discharging automatically in the selected appropriate photographic mode at a time of exposure. The controller selects either the auto-exposure-mode selecting mode or the flash-prohibiting/auto-exposure-mode selecting mode in response to an operation of the manual operation member. A similar camera with an external flash is also provided.

Title: Sex-specific insemination of mammals with low number of sperm cells
Inventor: SEIDEL GEORGE
IPC: A01K67/027
Filed: 1998-12-31
Abstract: Artificial Insemination is achieved for sexed mammalian offspring in a commercially practical manner and with dosages of insemination sperm which were not previously thought to be practical for commercial implementation. Improved insemination systems particularly adapted to use for sex-selected sperm sorting include systems which achieve superovulation and then multiple embryo production with sexed embryos. These systems combine with other techniques, including techniques for enhanced sheath fluid (3) and other strategies which minimize stress on the sperm cells (18), and potentially, a 2.9 percent sodium citrate sheath solution for bovine species and a hepes bovine gamete media for equine species. Improved collection systems (14) and techniques for the process are describeb so that commercial application of sperm samples as well as the resulting animals may now be achieved in the field.

Title: Gear changing method and apparatus
Inventor: VESTGARD BARD
IPC: F16H61/04
Filed: 2001-05-19
Abstract: A method of changing gear in an automated transmission having a multi-ratio gearbox comprises gradually engaging, via an actuator 62, a power shift clutch 80 until the torque transmitted by the power shift clutch 80 is equal to the torque produced by an engine connected to input shaft 12 by a take-up clutch 18. When torque equalization has occurred, a currently engaged gear is disengaged by, for example, moving clutch 42 via actuator 62 to its mid position. After disengagement of the current gear the power shift clutch 80 and/or the engine are controlled so as to synchronize the speed of the input shaft 12 with that of output shaft 22 for a new (second) target gear 23, 33 to be engaged. The new gear is engaged after a predetermined time period wherein the power shift clutch 80 and/or engine are controlled so that synchronization and acceleration of the input shaft 12 level off towards zero. Power shift clutch 80 and/or engine torque are controlled by a closed loop feedback having a step, a ramp or a non-linear command path.

Title: Mass spectrometer comprising vortex mass filter and analyser
Inventor: BATEMAN ROBERT HAROLD
IPC: H01J49/26
Filed: 2001-10-12
Abstract: A mass spectrometer is disclosed comprising a vortex mass filter/analyser. The vortex mass filter/analyser preferably comprises a chamber 1 with a central rotatable shaft 2 connected to a pressure reducing means. As the shaft 2 rotates, a vortex is created within the chamber 1. The centrifugal force on an ion in the vortex is arranged to be balanced at a certain radius of rotation within the chamber 1 by the electric force due to an opposed radial electric field. Ions having a certain mass to charge ratio are arranged to be maintained at a stable equilibrium at this radius and can then be selectively removed for further analysis. In other embodiments the detection of the ions of interest can happen within the vortex mass filter/analyser. The advantage of the present invention being that no magnetic field is required and the apparatus works at pressures around that of atmospheric pressure.

Title: Helical and spur gear drive with double crowned pinion tooth surfaces and conjugated gear tooth surfaces
Inventor: LITVIN FAYDOR
IPC: B23F9/02
Filed: 2000-06-28
Abstract: Helical or spur gear drive comprising a driven gear and driving gear wherein the driving gear has double crowned teeth defined as (i) an envelope to a family of surfaces generated by an imaginary skew or straight rack-cutter having a parabolic tooth profile in normal section and then (ii) as an envelope to a family of tool surfaces that are generated while the tool performs a plunging motion with respect to the driving gear in the direction of the shortest distance between the axes of rotation of the tool and the driving gear and tool plunging motion is varied by a parabolic function, whose variable is displacement of the tool in a direction parallel to the rotational axis of the driving gear. The driven gear has a tooth surface defined as the envelope to a family of surfaces generated by a rack-cutter which surface is parabolic cylinder or a plane. The generated pinion/gear tooth surfaces are in theoretical point contact at every instant and they produce a preselected parabolic function of transmission errors in the process of meshing. The pinion/gear exhibit reduced vibration and noise, reduced shift of bearing contact caused by misalignment, and reduced contact stresses due to convex-concave contact of tooth surfaces.

Title: Failure detection in coil circuits of fuel injection apparatus
Inventor: NISHIZAWA OSAMU
IPC: F02D41/20
Filed: 2002-01-15
Abstract: The circuit detects an abnormality (short or open circuit) in a single injector coil circuit, or a short circuit between the circuits of different injector coils in a multicylinder engine. Common ON/OFF elements 11 (TR13), 21 (TR42) feed drive voltage 3 to a group of cylinders 5, 8 or 6,7. Individual ON/OFF elements 13 (TR1), 14 (TR3), 23 (TR4), 24 (TR2), select the individual cylinders in the correct sequence. Off-surge detection circuits 35, 36 detect when the off-surge voltage Vs, created when the current through a valve coil is broken, exceeds a predetermined level. Failure, and the type of failure is determined from the absence or duplication of the off-surge signals. Low current hold circuits 19, 29 feed a reduced current holding signal to the coils after an initial high current actuates the coils.
