[Also in Divisions B7 and E2] A kit for constructing slides, climbing frames, swings, roundabouts, see-saws, and coasters comprises two channel-sectioned members 7 hinged together, a set of 12 ladders 6 and connectors 9 for connecting the ladders of the set to each other and for connecting the channel members to the ladders. Front and back axle assemblies (Figs. 13, 14, 15 not shown) may be secured to the channel-sectioned members when folded from the extended position shown in Fig. 8 in which they are utilised to form a see-saw to a back to back position to form a coaster. The wheels 18 of the front axle assembly 19B are mounted on swivel mountings 22 and may be steered by a steering column 27 associated with a steering linkage 25 which is associated with the front wheels. A seat 30 may also be secured between the channel members when folded in a back to back position. The channel-sectioned members may be provided with hooks e (Fig. 2 not shown) which cooperate with each other, when the channel-sectioned members are extended, to form a pair of rings through which a bar f may be passed to serve as a support to the channel-sectioned members when used in conjunction with the ladders of the set to form a see saw; the ladders are connected to one another to form a supporting frame which supports the bar horizontally so that the channel-sectioned members are supported by the frame for a pivoting movement. The toy may comprise a further bar and four supporting arms which are used in conjunction with two ladder frames and the extended channel section members to form a swing. The channel sectioned members when in the extended and inverted position may be supported by a base 33 (Fig. 17, not shown) to form a roundabout. The connectors include two-piece connectors consisting of two hollow arms 9 which are hingedly joined together and can be slid over the end of a side piece of any one of the ladders. The two arms can be folded to lie side by side, which is utilised for connecting the climbing frame, or held side by side which is used for connecting adjacent ladders. Nuts 4 provided on the channel-sectioned members can receive bolts passed through apertures in other components of the toy whereby the other components can be secured to the channel-sectioned members.

Abstract: 1491304 Television GENERAL ELECTRIC CO 22 Jan 1975 [11 Feb 1974] 2761/75 Heading H4F A solid state television camera comprises a substrate 70 in which a charge coupled device (CCD) in the form of an array 50 of light sensitive locations, is fabricated as described with reference to Figs. 1 to 6 (not shown). The structure of the array is identical to that described in Specification 1,431,209. Also fabricated in substrate 70 are: MOSFET switching transistors 81 to 84 and 91 to 94 connected respectively to row conductors X 1  to X 4  and column conductors Y 1  to Y 4 ; MOSFET gating transistors 101 to 104 and 111 to 114 similarly connected; and shift registers 106, 116. A scene to be viewed is focused on to the array by suitable optics. The camera further includes capacitors C, and C 2  for providing the integrand of current flow resulting from stored charges in the array being driven along the conductors under the influence of driving pulses from the shift registers. The integrands form component video signals. The column conductors are notionally grouped into two sets a, consisting of Y 1  and Y 2 , and b consisting of Y 3  and Y 4 . The video components are driven from storage locations in each row X 1  to X 4  sequentially and as follows. Components from locations connected to conductors of set a, on the relevant row, are simultaneously shifted from the CCD. The two components pass along respective ones of a pair of video channels No. 1 and No. 2 connected across the respective integrating capacitors C 2  and C 1  and these are followed, in a similar manner, by the components driven from locations connected to conductors of set b and so on for each remaining row. The simultaneously driven pairs of components, occupy the same time interval of twice the location scan period, and are multiplexed 174 for output as a composite video, by selecting components from each channel in alternation with a sample time of one location scan period. A colour signal is obtained if a vertical striped filter having alternate cyan and red elements is disposed in front of the array. A larger array may be employed wherein the column conductors are grouped into a larger number of sets a, b, c... each comprising three adjacent conductors, there being respective red, green and blue filters before the relevant locations in each of the sets. Other embodiments wherein the current integrand is derived from alternative circuits are described with reference to Figs. 9 to 12 (not shown).

Title: Improvements in electronic signal storage tubes
IPC: H01J31/62
Filed: 1953-02-06
Abstract: 726,077. Electron beam apparatus. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Feb. 6, 1953 [Feb. 15, 1952], No. 3417/53. Class 39 (1). A signal storage tube comprises an electronpermeable target having an insulating surface on which a charge pattern may be deposited by scanning the surface with an electron beam, means for varying the charges deposited on the surface by the beam in accordance with signals to be recorded, means for producing in the vicinity of the target a virtual cathode whose effective emission is controlled by the stored charge pattern, and means for allowing only the emission controlled by a selected part of the charge pattern to produce an output signal at any given time. In the tube shown in Fig. 1, the writing gun 2 is maintained at a potential of - 2 Kv, and electrons from it are accelerated by a wall anode 8 and a grid 4 connected to it and maintained at a potential of 1 Kv on to the target 6 which comprises a grid coated with insulation on the side facing the guns. The target 6 is maintained at a potential of - 2 volts and the grid 5 in front of it is near earth potential and is modulated by the signals to be stored so that as the unmodulated beam from the gun 2 scans the target, elementary areas of the insulated surface become charged to the instantaneous potentials of the grid 5; the electrons from the writing beam then pass on to a collecting electrode 7. The charge pattern laid down on target 6 is scanned by slow electrons from a gun 3 at a potential of + 5 volts; these electrons are modulated by the target and are focused on to an aperture in the electrode 7 so that they pass to an electron multiplier. The focusing is achieved by the spherical shape of grids 4, 5 and 6. In a modification, Fig. 2 (not shown), the reading gun floods the target to produce a composite stream which is scanned magnetically over the aperture in electrode 7 as in an image dissector tube. If the input signal is applied to the grid 6 instead of to the grid 5, the output signal corresponds to the difference between the input signals for two successive scans; it is also possible to apply the input signals to the anode. The tube may be used for conversion of standards in television, and in this case the frame frequencies need not be identical.
