Abstract: 1532249 Cathode-ray tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Nov 1975 [27 Nov 1974] 48192/75 Heading H1D A deflection coil, Fig. 2d, for a cathode-ray tube having a partly flared outer surface consists of a conductor which extends about a window in a number of turns, the coil being folded at four points around its periphery along folding lines 17, no two of which are aligned but each of which intersects all the turns, and such that in the vicinity of each folding line each turn crosses all the other turns. The coil is manufactured by folding an initially flat coil (Fig. 2a, not shown) such that portions of the plane of the turns on each side of each folding line are approximately orthogonal, Fig. 2b, and subsequently pressing to its final shape, of which Figs. 2c and 2d are a plan view and a rear view, in a jig; in the final shape, the turns at the folding lines are folded further until the portions of the plane of the turns on each side enclose an angle of approximately 0 degrees. The coil may be of circular or rectangular cross-section wire, or of printed circuit form; to avoid difficulties in folding coils of thick wire, a plurality of identical plane coils may be stacked together before being folded and pressed into the final shape together; the shape of the initial plane coil may be chosen to give a desired field distribution (e.g. Figs. 2a, 3a or 4a, not shown); or, for a more complex field distribution, a coil may be made by combining a plurality of coils derived from initial plane coils of differing shapes (Fig. 5, not shown).

Abstract: 1,127,251. Pulse generator circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 15 Dec., 1965 [30 Nov., 1964], No. 48582/64. Heading H3P. A pulse generator in which a delay line type pulse forming network PFN is charged from a supply and then discharged through a load R 1  connected to one end of the line on closing a first switch S 1  to generate a pulse, includes an auxiliary discharge circuit C, independent of the load, connected to the same end of the line on closing a second switch S 2 , and control means, P, G 1 , G 2 , whereby the first switch S 1  is closed at a variable time after or at the same time as second switch S 2 , thus diverting the current from the auxiliary circuit to the load. The pulse applied to the load therefore has a duration determined by the time between closing switches S 1 , S 2  (e.g. thyratrons or ignitrons). Load impedance R L  is slightly larger than the impedance Z 0  of the delay line, so that a small current still flows through the auxiliary circuit after S 1  is closed. This current takes the ripple from the delay line output whilst a flat-topped pulse flows through the load. A further switch S 3  is provided which, when closed, transmits a negative voltage wavefront down the delay line to extinguish S 1  and S 2  and so sharply curtail the output pulse at an instant dependent upon the time of closure of S 3 , as is described in Specification 1,088,761. Pulses from generator P travel down delay line D L  to trigger switches S 1 -S 3  via devices G1-G3 and transformers T 1 -T 3  at the correct instants.

IPC: E02D3/026
Filed: 1964-12-02
Abstract: 1,072,160. Motor rollers. STOTHERT & PITT Ltd. Nov. 30, 1965 [Dec. 2, 1964; Feb. 10, 1965], Nos. 49001/64 and 5769/65. Heading A1B. [Also in Divisions B1, B7, F2 and G1] The degree of compaction achieved by the action of a vibrating member R on material with which it is in contact has been shown to depend at any moment during the vibratory action on the length l of the major axis of the elliptical locus of a point on the member R and is assessed by measuring with a unit T at least one value related to l and producing therefrom a signal proportional to l which can be used to obtain a reading of the degree of compaction on a meter M and, when a preset value is reached, to provide a signal to light a lamp L and, if desired, to control the action of member R. The unit T may comprise two piezoelectric accelerometers responsive in mutually perpendiculars directions whose outputs are combined and integrated to obtain the instantaneous amplitude from which a peak reading meter M derives the required maximum values corresponding to the length l. Alternatively a single omnidirectional transducer can be used. In the travelling vibratory roller shown, Fig. 2, a motor E drives an out-of-balance shaft S in bearings 110 in a roll R mounted by bearings J, J<SP>1</SP>, having flanges 112 attached by rubber-in-shear mountings 113 to flanges 114 attached to the frame F. A variable speed transmission system 100 is arranged in the drive from the motor E to the roll R, whose speed may be automatically changed when a predetermined degree of compaction is acquired. The invention may also be applied to a vibratory poker, beam or limpet used in consolidating freshly poured concrete.

Filed: 1973-10-25
Abstract: 1451345 Making photographic colour diffusion transfer materials POLAROID CORP 25 Oct 1973 [25 Oct 1972] 49740/73 Headings G2C and G2X The sensitometry of a multi-colour photosensitive element comprising a support bearing blue-, green- and red-sensitive silver halide emulsion layers associated with yellow, magenta and cyan image dye-providing materials respectively is improved by forming a weak latent image in at least one of the emulsions by uniform exposure of the element to light of a predetermined intensity and wavelength range. Usually uniform exposure is so conducted that at least the green-and red-sensitive emulsions carry the latent image. The uniform exposure is preferably conducted by giving a uniform exposure to a first wavelength range which exposes each emulsion and to a second wavelength range which further exposes at least one of the emulsions. Best results are obtained when the intensity and wavelength range of the exposure are such that the slopes of the D log E curves of positive transfer images obtained upon subsequent imagewise exposure and development of the emulsions are in a more nearly parallel relationship with each other than in the absence of the uniform exposure. Uniform exposure may be effected after ageing the photo-sensitive element until stable sensitometric properties are achieved. The total amount of the uniform exposure may be such that it reduces the maximum reflection density upon subsequent imagewise exposure and development by not more than 0À2. The intensity of the uniform exposure may be <SP>1</SP>/ 2500 -<SP>1</SP>/ 400  of the exposure needed to give fully exposed areas. The image-dye providing material may be a dye developer. The element may be of the multi-layer type or of the screen type. The invention also comprises apparatus for assembling the above element including a rupturable container releasably holding a processing composition as described in Specification  1342572 but also comprising a pre-exposure station 84, 86.
