A primary or secondary cell comprises an anode of an electropositive metal and a cathode composition comprising a mixture of carbon, an electrolyte, and a depolarizer compound which has the formula wherein R 1 , R 2 , R 3 , R 4  are each H, C 1-8  alkyl, aryl, substituted aryl, cycloalkyl, aralkyl, alkoxyalkyl, cyanoalkyl, haloalkyl, nitroalkyl or alkenyl groups or R 1  and R 2  or R 3  and R 4 , being alkyl, may be joined by a direct link or through an N, O or S atom to form a heterocyclic ring. The depolarizer, a substituted azodicarbonamide or azobis (formamide), may be added as such, or formed in situ by oxidizing the corresponding substituted biurea by charging the cell. It is preferably finely divided e.g. of 20-10 Á, better about 1 Á, particle size, and preferably constitutes 10-50 weight per cent of the mixture. The anode may be e.g. of Zn, Mg or Al, which may contain alloyed Mn, Zr, Ce or Ca. Conventional separators of kraft paper, which may be impregnated with starch, carboxymethyl cellulose or cereal paste, or of vegetable parchment, or of porous films of nylon, polyester, polyolefin, polyacrylate, polyvinyl acetate or polyvinyl chloride may be used; laminated " Cellophane " (Registered Trade Mark) is preferred. The electrolyte may suitably be an aqueous solution containing halide and e.g. ammonium, zinc, manganous, or mercuric ions, at concentrations totalling from 30 g.p.l. to saturating amounts. For primary cells solutions containing 17 weight per cent ZnCl 2  and 27 weight per cent NB 4 Cl are useful; for secondary cells 17 weight per cent ZnCl 2  and 27 weight per cent NH 4 Br is preferred.

Patent GB-2058521-A (GB)
Title: Signal/noise ratio measurement
IPC: H04B1/64
Filed: 1979-09-04
Abstract: A method of detecting the signal- to noise ratio of an audio frequency tone used in LINCOMPEX voice processing equipment (11) for controlling the demodulation level of the received speech signal in proportion to its amplitude. The noise on the control tone is band-limited in a filter (1) which filters the control tone from the speech signal, thus producing a first signal with a noise envelope. The first signal is applied to a rectifier (2) and filter (3) in series to produce a second signal with a D.C. voltage level proportional to the tone and a ripple voltage proportional to the noise. The D.C. voltage level is blocked by a capacitor (4) and the ripple voltage applied to a further rectifier (5) and filter (6) in series to produce a third signal with a D.C. voltage level proportional to the noise. The third signal is compared with a reference voltage proportional to the D.C. voltage level of the control tone in a detector 7, whose output actuates a mute and/or warning lamp (8) to control the demodulation level. <IMAGE>

Title: Head up display
IPC: G02B27/01
Filed: 1980-01-17
Abstract: An aircraft head-up display system has an image combiner 1 comprising a block 20 of transparent glass, and a plate 22 of transparent glass cemented to the block; the plate 22 carrying a reflection holographic element 24 (or a transmission holographic element in Figure 4, not shown) on its surface abutting the block. As shown, light from a display is projected into the combiner through one edge 4, at an acute angle onto its front face 21. The light is then reflected rearwardly through the holographic element 24 to the rear face 27 of the plate where it is reflected forwardly again. The holographic element reflects some of the light incident on it from the successive reflections within the combiner at right angles to the surface of the plate, forwardly through the front face of the combiner and into the line-of-sight 2 of the observer. Successive reflections cause light to emerge at several locations 30, 31, 32 along the length of the combiner to provide an extended field of view. <IMAGE>

Title: Automatic image checking device
IPC: G06T1/00
Filed: 1980-06-25
Abstract: A device for checking images (e.g. on microfilm 10) comprises in common with known equipment, scanning array 24, a field of view and means 12 for providing relative movement between the two. In the known equipment, the image is scanned orthogonally to the direction of relative motion, which results in poor data collection for image edges orthogonal to the direction. In the present invention the scans are inclined with respect to the direction of relative motion and sampling windows along each scan track the edge images. This tracking is improved by allowing for the displacement of a sampling window by a preset distance along the scan in accordance with the analysis of the data within that window in the previous scan if that analysis failed to detect the image edge. <IMAGE>
