Title: Infra-red radiation imaging device arrangements
Inventor: BAKER IAN MARTIN
IPC: H01L27/148
Filed: 1982-07-28
Abstract: An imaging device arrangement comprises an array of infra-red radiation detector elements (10) and signal-processing circuitry including parallel charge-transfer lines (30). The detector elements (10) which may be photovoltaic diodes of cadmium mercury telluride are coupled to the charge-transfer lines (30) via input gates (61) at locations (2, 3) which are spaced along the lines (30) and which are associated with individual groups (a to z) of clocking electrodes (31 to 34) of the lines (30). A background-storage electrode (62) and a threshold gate (63) are present at each location (2, 3) to subtract a given background level (77) from the charge-signal and so to transfer only that portion (78) of the charge-signal remaining after subtraction. So as to minimize the pitch of the detector elements (10) and of the parallel lines (30) and maximize the charge-capacity of the parallel lines (30), the background-storage electrode (62) at each location (2, 3) is formed by at least part of at least one of the clocking electrodes (31 to 34) of the associated parallel line (30). The background storage well (72) below this clocking electrode or electrodes is coupled to the associated radiation detector element (10) by the input gate (61) and to a remaining-signal storage well (74) by the threshold gate (63). The threshold gate (63) and the remaining- signal storage electrode (64) may also be formed by at least part of at least one of the clocking electrodes (31 to 34). After collecting the remaining-signal charge (78) in the remaining-signal well (74) but before transferring it along the line (30), the subtracted charge (77) is drained away from the line (30), for example by draining along the line (30), or transverse to the lines (30), or via the detector elements (10). <IMAGE>

Title: String instrument with height-adjustable fixing of the strings
Inventor: WEBER ULRICH
IPC: G10D3/04
Filed: 1982-09-02
Abstract: The invention relates to a string instrument with height-adjustable fixing of the strings (4) on a saddle and/or bridge, lying across the neck (2) or body of the instrument and fastened thereto, in the form of an elongate base part (5) into which a number of screws (8) corresponding to the number of strings (4), for the height adjustment of the strings are sunk in a row at the same spacing as that of the strings (4). On the base part, a number of blocks (13) corresponding to the number of strings (4), are arranged, which blocks (13) are provided with string-guide slots (9) are laterally guided on the base part by webs (14) and are height-adjustable relative to the base part (5) by means of screws (8) in active engagement with the blocks. Alternatively the screws (8) project above the base part (5) and are themselves provided with the string-guide slots (9). In either case the height of the strings (4) can be adjusted without having to slacken them off first. <IMAGE>
Patent GB-2109207-A (GB)
Title: Improvements in or relating to interference cancellers
Inventor: ALSBERG DIETRICH ANSELM
IPC: H04B3/23
Filed: 1982-10-20
Abstract: The invention is a two-stage echo canceller arrangement including a first echo cancelling stage (20) and a second echo cancelling stage (18). The first a. echo canceller adapts an input signal (x(k)) to synthesize a first estimate of an echo replica signal (@1(k)). A combiner (28) subtracts this first echo replica signal from the actual echo signal to generate a first echo cancelled signal (e1(k)). A control unit (30) monitors the change in value of the echo cancelled signal, and locks the adaptation process of the first echo canceller when the first echo cancelled signal is sufficiently less than the input signal, usually 6 dB of the input signal, to allow a near-end speech detector (23) included in the second stage to function correctly, ie to reduce the echo to a level below that at which it might be wrongly identified as near end speech. The second echo canceller, which is disposed after the first echo canceller, functions in a similar manner as the first echo canceller, and, unless inhibited by the detection of near end speech, continues to operate after the first echo canceller is locked until the echo cancelled signal produced by the second echo canceller is approximately equal to zero. <IMAGE>

Patent GB-2144269-A (GB)
Title: Electroluminescent device: method and product
Inventor: CATTELL ALAN FRANK
IPC: H05B33/28
Filed: 1984-07-23
Abstract: A method of electroluminescent panel manufacture in which a doped zinc chalcogenide phospher film-for example manganese doped zinc sulphide, is deposited upon an electrode bearing substrate in the presence of an hydrogen enriched atmosphere - for example a 90%: 10% argon:hydrogen atmosphere. This is followed by rapid anneal treatment, the substrate being raised quickly to a temperature of 450 DEG C, or greater, and cooled rapidly. It is preferable that, prior to film deposition, the substrate is pretreated by baking in the hydrogen enriched atmosphere. An additional current density limiting film may be applied - a film of low resistance cermet material - for example silica/nickel 20% Ni in SiO2, or a film of amorphous silicon.
Patent GB-2165957-A (GB)
Title: Checking aiming apparatus alignment
Inventor: BRIGNALL NICOLAS LAURENCE
IPC: G02B23/12
Filed: 1984-10-18
Abstract: Aiming apparatus 10' for observing the direction of a designating beam from laser 15 by thermal imaging means 12 or optical sighting means 35 (in the form of a tv camera) is checked for alignment of the nominally parallel 'thermal', optical and laser sightlines 14, 37 and 16 when focussed at infinity by means of alignment checking means 40 disposed in front of the aiming apparatus. An enclosure 41 contains a body 26 at the focal point of a concave mirror 25 and a periscope arrangement 29' to divert the collimated laser beam on sightline 16 via mirror 25 to heat body 26. Thermal radiation given off is reflected and collimated by mirror 25 into a beam parallel to the laser sightline 16 and within the field of view of thermal imaging means 12. Visible laser radiation is passed by beam splitting reflector 30' of the periscope and reflected by roof prism 43 towards the tv camera 35. If either received image is offset from the respective sightline 14 or 37 this indicates misalignment between that and the laser sightline. Non-visible laser radiation, e.g. from a CO2 laser at 'thermal' wavelengths, may be caused to generate a discharge at the focus of the mirror including thermal and optical radiation at the body and a further periscope arrangement employed to direct the optical radiation generated to the sighting means (See Fig. 3.) <IMAGE>
