IPC: B24B41/06
Filed: 2003-11-21
Abstract: A grinding machine comprising: a base; a wheelhead 10 with a grinding wheel 12 and wheel drive mounted thereon; a workholder 23 and drive means for rotating a workpiece 22 mounted therein about at least one axis 24; workholder drive means for moving the workholder 23 relative to the machine base; wheelhead drive means for moving the wheelhead 10 relative to the machine base and a programmable computer based control system for independently controlling the drives to perform a grinding operation by engaging the wheel 12 with the workpiece 22. The wheelhead 10 is moveable along two orthogonal x and z axes, 25 and 19, in a first plane in which movement along the x-axis 25 moves the wheel 12 towards or away from the workholder 23; the workholder 23 is rotatable about a c-axis 24 that is parallel to and in the same plane as the axis of rotation of the wheel 12. The common plane being coincident with or parallel to said first plane. During engagement between the wheel 12 and workpiece 22, the control system controls the rotational movement of the workpiece about the c-axis 24 and the movement of the wheelhead 23 along the x and z axes, 25 and 19, so as to determine how the workpiece 22 is to be ground. Varying oscillatory movement can be used to grind flat slots. A plurality of wheel dressing tools 26, 28 and 30 or additional machining tools (figures 3 and 4, 42, 43) may also be provided.

Title: Pseudo reistive converter
Filed: 2008-01-08
Abstract: An electrical power converter comprising an inductor 3, an oscillator 1 which operates a first switch 2, and a diode 4 or second switch to the output. The electrical power converter gives a pseudo resistive input characteristic which is intrinsic to its switched inductor operation and does not require feedback, though feedback can be used to modify its characteristic. As the supplied input voltage is increased, the input current also increases. The output characteristic is to deliver an energy pulse as the inductor is de-energised.

Title: Hybrid predictive coders and decoders for digital video signals
IPC: H04N7/50
Filed: 1990-09-06
Abstract: In a coder for digital video signals, the difference between the ditigal video signals and prediction signals is subject to a transform prior to quantisation. In particular, a transform applied to the values of a block of pixels to produce sets of coefficients in the spatial frequency domain.

The coder further includes means (20) for adding the prediction signal to the output of the local decoder (18) and a framestore (22) which receives the output of the adding means (20). A multiplier (26) multiplies the output of the framestore (22) by a factor slightly less than unity to form the prediction signal.

Abstract: PCT No. PCT/GB90/00025 Sec. 371 Date Aug. 31, 1990 Sec. 102(e) Date Aug. 31, 1990 PCT Filed Jan. 9, 1990 PCT Pub. No. WO90/08024 PCT Pub. Date Jul. 26, 1990.In a method and apparatus for formation of an extruded product from material containing fibrous, molecules or other constituents succeptable to alignment, while the extrudate is still molten and moving through the die (5), in the direction of the extrusion axis (11), it is subjected to pulsating displacements in a direction transverse relative to that axis. These displacements give rise to a shearing action within the material, resulting in a degree of transverse orientation of the constituents. This orientation may be "locked in" to the extruded product when the melt solidifies (40), so improving the transverse strength of that product, and/or may correct an unwanted orientation (from 112, FIG. 16) that existed in the melt upstream of the point where the pulsating displacements were applied. The displacements may be applied by the synchronized operation of pistons (20-27), operating in chambers (17) which open into the die cavity (18) at separated locations all lying in the same transverse plane. The extrusion of products of rectangular, tubular and other sections is described, as are various methods (8a, 8b, 9, 10, 37) of applying forced cooling to the die to accelerate the solidification of the molten product.
