Abstract: 1423369 Fluidized bed electrolysis cell. ELECTRICITY COUNCIL 17 Sept 1974 [24 Sept 1973] 44650/73 Heading C7B In an electrolylitic cell having at least one rigid flat or curved plane electrode made of apertured material or material with surface irregularities, there is provided adjacent said electrode a fluidized bed of non-conductive particles. A rectangular or cylindrical cell may be used with or without diaphragm(s) of ion-exchange or synthetic fibrous rigid or flexible material. The particles, e.g. of glass, sand or plastics of dimensions 0À5-2mm, may surround both electrodes of the cell or may be only in an anolyte or catholyte compartment. The electrode may be a cathode e.g. of Cu or Ti and have a mesh or roughened (e.g. sinusoidal or pyramidal protrusions) surface of dimensions greater than those of the particles. Fluidization may be by electrolyte flow, with or without recirculation, using a ceramic distributer with slots, holes or pores (100-300Á). The cell is useful in recovering e.g. Cu from waste rinsing, pickling and other solutions. For this purpose mesh anodes of Pb (which may include Ag or Sb) are used. The Cu is a coherent plated deposit and may be used as an anode in a Cu plating cell.

Abstract: 1,009,537. Valve supply circuits. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Nov. 13, 1963 [Nov. 15, 1962], No. 44838/63. Heading H3W. In a photomultiplier supply circuit the anode A and cathode K are interconnected by a chain of resistors R and the dynodes D 1 -DN are connected to intermediate points in the resistor chain. According to the invention a first stabilized H.T. source is connected between the cathode and one of the dynodes, DN-q and a second stabilized H.T. source between the same dynode and the anode. The output is taken from a resistor Rd in the circuit of the dynode common to both supply sources; alternatively, if this comprises the last dynode before the anode, the output may be taken from a resistor R A  in the anode circuit. To improve the high-frequency response capacitors C may be connected across the resistors R and a capacitor Ca or C A  across resistors Rd or R A  respectively. It is stated in the Specification that the arrangement line arises the amplitude and frequency response of the photomultiplier circuit.

Title: Methods for taking and composing steroscopic pictures
IPC: G03B35/24
Filed: 1973-09-27
Abstract: 1445583 Stereoscopic photography DIMENSIONAL DEVELOPMENT CORP 27 Sept 1973 [27 Sept 1972] 45325/73 Heading G2A A stereoscopic picture is prepared by photographing the object field from a plurality of diferent vantage points, at least one of the variables (a) focal length, (b) distance between vantage points, (c) enlargement ratio, (d) the distances from the path of the vantage points to the nearest, farthest, and main elements of the object field, being controlled so that the change between adjacent vantage points in the parallax value between the image of the main element and one of the other elements is maintained within a predetermined range. Fig. 6 shows an object field comprising a main subject element 80, a near element 76, and a far element 78. For a high quality stereoscopic picture the parallax, i.e. the apparent shift in position of an element of the object field due to relative change in the position of the element and/or the place from where the element is viewed, should not be too small or too large, but have an optimum value, so that all the elements of the object field should be in sharp focus. The theory is explained with reference to the taking, from different vantage points, of a picture having near, far, and main elements A, B, K, at respective distances a, b, k from the camera objective plane, and, after development of the negatives, their projection on to a lenticular screen backed by a photo-sensitive film, Figs. 1, 2, 3 (not shown). The conditions for  optimum parallax are discussed, and equations are derived by means of which the photographer can choose and control the parallax by control of one or more of the variables set out above. Fig. 12 shows a camera which may be used in carrying out the method of the invention. This has five equally spaced lenses, and some or all of the lenses may be used to give different inter-lens distances (i.e. different distances between vantage points). The camera body itself may be constructed so as to permit expansion or contraction, and may also have interchangeable lenses with different focal lengths. Alternatively separate cameras sliding on a common base may be provided. The camera 120 (Fig. 14) may be slidably mounted by means of a support 122 and a slide 118 on a base 114. The base is provided with means for accurately stepping the slide along a series of positions marked on a scale, Figs. 18A, 18B, so as to position the camera positively at a series of equi-spaced vantage points. A number of different scales are provided, for different distances between vantage points. The scales have transverse notches 170 thereon, and the slide carries a spring- loaded pawl whose tip, as the slide moves over the scale, engages in one of the notches 170. Thus the slide is positively positioned at that location.

Title: Device for laying the sleepers of a track
IPC: E01B29/06
Filed: 1975-10-31
Abstract: This apparatus permits sleepers, in particular of a curved track section, to be offset in their final, curved outline. For this purpose, a longitudinal load-bearing member (9) is provided with an elastically deformable laying beam guide (2) which is set to the form of track curve desired in each case by means of power-driven assemblies (13, 14). This longitudinal load-bearing member (9) is used to receive, secured and deposit the individual sleepers. On the longitudinal load-bearing member (9) there are arranged sleeper retaining devices or rail detaining devices, e.g. gripper pairs (16), which can be moved laterally together with laying beam guide (2) and vertically together with the longitudinal load-bearing member (9). The longitudinal load-bearing member (9) is borne, such that it can be vertically adjusted, by two portal frames (4) which are arranged one behind the other and can be displaced on auxiliary rails (7). <IMAGE>

Title: Colour television cameras

IPC: H04N9/077
Filed: 1971-10-08
Abstract: 1410765 Colour television EMI Ltd 27 Sept 1972 [8 Oct 1971] 46846/71 Heading H4F A single-tube colour television camera uses striped filters having stripes at equal and opposite angles to the line scanning direction to produce a chrominance signal including a subcarrier modulated by two-primary colour difference signals (e.g. R-G and B-G) at different phases and also a separable index signal. In one embodiment (Figs. 4, 5, not shown) one filter has stripes in a repeating sequence of transparent, magenta, cyan, magenta and the other filter has transparent, magenta, yellow and magenta stripes. The resulting output signal includes R-G and B-G signals at the same frequency respectively advanced and retarded in phase from line to line and respective index signals at half the colour carrier frequency also respectively advanced and retarded in phase. The chrominance and index signals are separated using a delay equal to 360 degrees of the colour subcarrier, an adder and a subtractor, the R-G and B-G chrominance and index signals being separated using further delays, adders and subtractors, the index signals being used to demodulate the resulting chrominance signals. In an alternative embodiment, Fig. 3, one filter has alternating yellow and magenta stripes to produce a B-G signal and the other filter has alternating cyan and magenta stripes to produce an R-G signal, which signals are separated by a bandpass filter 9. The scanning spot of the pick-up tube is wobbled at a frequency of W3 to produce phase changes of #/2 relative to the phase produced by a non- wobbled spot, to produce the separable index signal. The resulting signal from the pick-up tube is passed to a bandpass filter 26 to pass signals at twice the colour subcarrier frequency, and to multipliers 26, 25 which also receive signals at the wobble frequency and twice this frequency respectively to provide signals of the signs of the sine and cosine of the difference in the phases of the B-G and R-G signals to circuit 27 which calculates this difference to within 45 degrees. The result is added to and subtracted from the output of 24 and the resulting signals are frequency halved at 22, 23 to produce signals of -carrier frequency and approximately the same phases as the R-G and B-G signals. The signals from 22, 23 are used to associate the correct signal with the B-G aind R-G signals, whose moduli are determined by detectors 12, 13. Frequency detectors 21, 22 are reset if necessary at the beginning of each line to produce the correct R-G output when scanning a green index stripe.
