Patent GB-402384-A (GB)
IPC: G03C7/14
Abstract: 402,384. Colour kinematography. SOC. CINEMA-TIRAGE L. MAURICE, 66, Rue St. Denis, Gennevilliers, Seine, France.-(Assignees of Richard, A. A. P. ; 97, Rue Lemercier, Paris.) Feb. 24, 1932, No. 5539. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 22, 1932]. [Class 98 (ii).] A single multicolour lenticular colour - record image is printed by contact on a film E from one or more negative or positive non- lenticular films F bearing separate component colour-record images by illuminating each record in turn from a source so disposed and restricted as to correspond to the light beam by which the particular record will be projected through the usual colour-selecting filter. The printing light beam for each component is of slightly smaller angle than the corresponding projecting light beam in order to avoid overlap of the elementary printed images. A correcting lens M may be placed in front of the films, the lens being spherical when the film E bears picot lenticles and cylindrical when it bears cylindrical lenticles. For tricolour work the illuminant may comprise three lamps 1, 2, 3 successively energized, or a single lamp displaced between successive exposures. It may be in the form of an incandescent filament of determined breadth, or a diffused light masked by a movable diaphragm of determined aperture. It is stated that the method may also be used for analysing a single lenticular original into separate monochrome components, and that black or colour-record relief images may be synthesized from, or analysed into, their right and left components by the method.

Title: Improvements in or relating to electrical amplifiers for magnetic thin, film stores
IPC: H03K17/64
Filed: 1963-10-16
Abstract: 1,059,827. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 16, 1963 [Oct. 31, 1962], No. 40743/63. Heading H3B. The common bit write/sense line of a thin film magnetic store is connected to one end of a centre-tapped primary winding of a transformer to the tap of which is applied the bit drive pulses, and the secondary winding of the transformer is connected to a sense amplifier. In one embodiment, Fig. 3 (not shown), two metal baseplates (11), (12) carrying electrically conducting carrier plates on which are mounted matrices of anisotropic thin films, are mounted back to back. A plurality of spaced apart parallel write/sense lines are arranged across the upper and lower surfaces of the composite store one of the ends of each line being connected to the baseplate (11) or (12) and the other end being connected to one end of a primary winding of a transformer 53. Arranged orthogonal to the write/sense lines are a plurality of spaced apart parallel word lines each connected at one end to a driver and at the other end to one of the baseplates. In operation information is stored by applying a word pulse to a selected word line to rotate the magnetization vectors into the hard axis and then before the word pulse ends applying a pulse from write amplifier 51 to the selected write/sense line via the centre-tapped primary of transformer 53, Fig. 4. The write pulse determines which direction the magnetization vector of the selected bit returns to in the easy axis at the cessation of the word pulse. For read out a word pulse is applied to the selected word line and the induced voltage along the associated write/sense line 41, 42 is fed via transformer 53 to sense amplifier 52. In order to prevent the bit pulses overloading the sense amplifier 52 during writing in an inhibit gate is provided between the input 521 and output 522 of the amplifier. Transistors 554 and 555 are rendered non-conducting during the passage of bit pulses by means of pulses passed through delay means 551 and a rectifier (not shown) to the bases of the transistors. During read out no bit pulses are generated by the write amplifier and hence the transistors are not inhibited and sense signals pass through the gate from transformer 53. The sense/write lines 41, 42 are terminated by their characteristic impedances Z. In the arrangement of Figs. 1, 2 (not shown) only one base plate and associated films are employed and the transistors of the inhibit gate are replaced by diodes.
