Title: Electrochromic cell.
Inventor: BOHNKE ODILE
IPC: G02F1/15
Filed: 1992-07-08
Abstract: An electrochromic cell comprises a substrate bearing an electrode, a persistent electrochromic layer, an electrolyte layer, and a counter-electrode on a second substrate, at least one such electrode and substrate being transparent. The electrolyte layer includes a lithium, cation donor material, for example lithium bromofluoride, which, Under the influence of a potential applied between the electrodes, donates lithium cations for reversible insertion into the electrochromic layer to modify the colour of the electrochromic material. The electrolyte layer also includes an additive such as lithium paradiphenolate which is selected to effect reversal of such colour modification by chemical reaction in the absence of such potential. In addition to allowing the cell to return to a ground state in the event of electrical failure, such additive may also increase the working life of the cell.

Title: Dynamic non-coherent cache resizing mechanism.
Inventor: JARVIS NEIL ALASDAIR JAMES
IPC: G06F12/0893
Filed: 1992-10-01
Abstract: A dynamic cache resizing mechanism permitting a non-coherent cache memory to be altered in size during operation. A cache utilization monitoring system determines whether the cache size is optimised for a particular application and environment, and if it is not, modifies a selection process to resize the cache address space. The non-coherent property of the cache is utilized to permit the change of selection process during use, and the choice of selection process may be effected to take into account the proportion of live cache entries which will remain accessible after resizing, and the proportional change in size of the cache during a resizing operation.   <IMAGE>

Title: Preparation of optical fibre ribbon ends
Inventor: CHAPPELL PAUL STEPHEN
IPC: G02B6/25
Filed: 1992-11-19
Abstract: A method of preparing an end of an optical fibre ribbon comprises the steps of supporting such a ribbon (1) so that it extends axially through a passageway in a sleeve-form holder (24); introducing a potting compound (28) into one end (25) of the holder, so that the potting compound (28) fills the passageway space around the ribbon (1) at a location adjacent to the said one end; cutting off a portion of the ribbon (1) that projects from the said one end of the holder, so as to leave the remaining ribbon portion in the passageway with a cut end adjacent to the said one end; and polishing the cut end while the said remaining ribbon portion is still held by the potting compound (28) within the holder. In such a method, during polishing the cut end of the fibre ribbon is held firmly and intimately around its outer surface by the potting compound. The potting compound serves to prevent the forces generated during the polishing process from altering the shape of the ribbon or displacing the fibres within the ribbon from their original positions. <IMAGE>

Abstract: A rangefinder of the active triangulation type has a position-sensitive sensor with a plurality of pairs of terminals 71, 74; 72, 75; 73, 76 along its length. In order to correct for any misalignment between the sensor and an associated light-receiving lens, the rangefinder measures the range to a target of known range, using the output from terminals 72 and 75; if the measured range is approximately correct, terminals 72 and 75 are used subsequently, otherwise terminals 71 and 74 or 73 and 76 are used depending on whether the measured range is too great or too small. Output corrections are also determined and stored for applications to subsequently determined outputs. <IMAGE>
Patent GB-931738-A (GB)
IPC: G03B39/00
Abstract: 931,738. Streak and framing cameras. BECKMAN & WHITLEY Inc. Oct.25, 1961 [March 3, 1961], No. 38180/61. Class 97 (1). A combination streak and framing camera comprises a beam splitter for dividing a focused beam from the event to be recorded into two separate paths, separate optical systems directing the separate beams towards a rotating mirror at different angles, and means for forming streak type and framing type images from the respective reflected beams. As shown in Fig. 1, a focused beam from objective 11 is split into two paths A and B by a beam splitter 12. The reflected beam A is directed on to the rotating mirror 17 by a mirror 15, and forms frame images on film 25 by means of relay lenses 20, 21, 22 and corresponding apertures in plate 23. The direct beam B, after passing through a narrow slit 30, falls on mirror 17 at an angle different from reflected beam A, and forms a streak image on the arcuate film 33. The beam splitter 12 can have the hypotenuse of the right-hand prism fully silvered except for a thin strip in the centre, and the slit 30 can then be dispensed with. The apparatus can be arranged so that either a frame or a streak image can be obtained. To this end, the beam splitter 12 is mounted on a rotatable plate which carries also a mirror and an aperture. If the plate is rotated so that the mirror instead of the beam splitter intercepts the beam from the objective 11, then only a frame image is obtained, while if the plate is rotated so that all the light passes through the aperture therein, then only a streak image is obtained.
