Patent GB-2463989-A (GB)
Title: LED array fabrication
Inventor: WOODGATE GRAHAM JOHN
IPC: H05B44/00
Filed: 2009-10-01
Abstract: The LEDs (72,74) are fabricated as a monolithic structure on a semiconductor wafer and are separated by sawing, cutting etc. Selected non-adjacent LEDs are removed from the diced monolithic wafer and transferred to a heat dissipating substrate in a single process step whilst maintaining their relative positions and separations. An array of lenses 122, 124 or reflectors is also transferred onto the LED assembly formed on the heat dissipating substrate. The LEDs typically have dimensions of 25-100 microns which reduces losses due to internal reflection and increases light output. The density of the LED assembly on the heat dissipating substrate is smaller than the density of the LEDs as formed on the monolithic wafer, maintaining the relative positions and orientations of the transferred LEDs in this way ensures that heat can be effectively removed from the LEDs. The manufacturing efficiency is improved in comparison with conventional pick and place techniques where individual LEDs from the monolithic wafer are selected and transferred to an LED array substrate in a sequential manner. The light emitting elements have a width/diameter of less than or equal to 300 micrometers.

Title: Polarised 3D stereoscopic display to prevent crosstalk
Inventor: JUNG SUNGMIN
IPC: G02B30/25
Filed: 2009-12-16
Abstract: A 3D stereoscopic image display device comprising a polarisation conversion device to convert light from the display into a first polarised light in response to a first driving voltage during an Nthframe period and to convert light from the display into a second polarised light in response to a second driving voltage during an (N+1)thframe period, wherein the time phase at which scanning of the image data starts is synchronised differently to the phase at which scanning of the driving voltage starts. The duty ratio of on/off timings of the gate lines and scan lines for the left and right eye data may be varied by a time shifter. The polarisation conversion device is a retarder panel which may have a half-wave plate optical axis characteristic. The device prevents crosstalk from occurring between the left-eye and right-eye images of polarisation glasses by making the on/off timings of the display's scan electrodes and the polarisation conversion device different in order to give an identical response characteristic.

Title: Machines for machining slots in workpieces
IPC: B23F23/00
Filed: 1972-03-03
Abstract: 1424353 Gear-cutting and grinding machines CRANFIELD INSTITUTE OF TECHNOLOGY 2 March 1973 [3 March 1972] 10171/72 Headings B3K and B3B [Also in Division G3] A gear cutting or grinding machine comprises a rotatable work support 13, a tool support 1 which can be oscillated about a centre 8, and supports a tool 5 for rotation about its own centre spaced at distance R from centre 8, and an electrical master-slave servo system for controlling the relative movement of the work and tool supports. Support 1 is oscillated by a belt 3, Fig. 1, coupled to a reciprocating belt carrier 2. In a modification, the oscillations are produced by a D.C. torque motor mounted on the axis of the support, (dotted lines in Fig. 2), and controlled by a digital computer 48, and a digital-to-analogue converter 49. Supports 1, 13, are provided with optical gratings 9, 17, respectively, which co-operate with reading heads, 11 and 18, the heads being coupled to synchronizing means which controls the operation of work-driving motor 15, the grating 9 being adjustable on slides 9a, 9b, so as to displace its axis from axis 8 of support 1 by distances F, P when grinding or machining corrected gear teeth. In addition to, or instead of, this adjustment, a signal can be sent to a comparator 29, Fig. 3, by a reading head 44 which provides pulses when a cam 41 rotates with tool support 1 and actuates a push rod 42 which carries a linear grating 43, the pulses being used to vary the angular position of the workpiece 16. In operation, in the case when F and P are set at zero (no correction) the signals from heads 11a, 11b, Fig. 3 are summed up at 39 to form composite sine and cosine signals which are multiplied and shaped at 19 and divided by N at 22. Reading heads 18a, 18b feed a device 28 similar to 39, the signals are multiplied and shaped at 27. The output from divider 22 is fed via an electronic switch 26 to a phase comparator 29 where the pulses are compared with those from device 27, and any error produces an output which is fed to a digital to analogue converter 30 and thence to the winding of motor 15 through a servo-amplifier 31, to thus regulate the motor speed. An adjustable gain discriminator 32 may be provided. When one tooth is completed on the workpiece 16, the latter is indexed so as to bring a further tooth into position, and this indexing corresponds to a known number of pulses at the outputs of device 27, and this number is preset in an indexing device 33 connected to counter 29 by an electronic switch 34. This operation produces a curvedtooth bevel gear with teeth of involute form. Tip and/or root relief correction Figs. 4-5 (not shown) is produced by offsetting the centre by amounts of F and/or P. An embodiment of the invention provides a control system to be used on a gear cutting machine in which the existing mechanical control 50, Fig. 7, for the tool support oscillation is retained without the need for electronically controlled indexing, the system is a simplified form of the system Fig. 3.

Abstract: 861,975. Controlling nuclear reactors. GENERAL ELECTRIC CO. Ltd. March 18, 1959 [March 31, 1958], No. 10240/58. Class 39(4). Distortion of the flux distribution in a reactor core is corrected, without affecting the total flux, by using a pair of absorbing members in different regions of the moderator so that when one member moves into the core the other moves out. Absorbers 8, 9 are hung, in channels, at opposite ends of the core. Their driving means are connected to a control device 21 which ensures that the total flux in the core is not affected by movement of the absorbers, while variations from symmetry of the flux can be corrected. In another embodiment, the two absorbers are suspended from the same driving means but are separated by a rod which does not absorb neutrons strongly.
