Title: Improvements in electrical computing apparatus
IPC: G06G7/70
Filed: 1946-06-26
Abstract: 620,496. Calculating-apparatus. ROBERTSON, D. R., COE, A. E., and BREWER, A. W. June 26, 1946, No. 19169. [Class 106 (i)] [Also in Group XXXVIII] Apparatus under the control of the pilot for computing the total load and the position of the centre of gravity of an aircraft comprises a number of resistances individually adjusted to the value of each load element and another set adjusted to the moment of each of these loads, the total values of each being compared in a bridge circuit or by means of a ratiometer. A particular application of the invention is to keeping the pilot informed of changes in the position of the C. of G. as fuel is drawn from different tanks. The resistances may be adjusted by the fuel gauge itself. In the embodiment shown in Fig. 2, the sliders of resistances 101, 10A-10R are adjusted to the values of the various items of load which they represent, these slides being gauged to the respective movement resistors 14<SP>1</SP>, 14-14R. A standard resistance 13 is paralleled across these two arms. In the upper position of the three-pole, two-way switch 12<SP>1</SP> the current in the " load " resistors is compared direct with that in the standard 13 and the loaded weight indicated on the lower scale 24 of the ratiometer. In the lower position of this switch the load and moment resistors are compared, a padding resistance 29 being cut out of circuit to bring the ratio on to the scale 25 which indicates the position of the centre of gravity from some datum point. Lamps 34 and 35 indicate whether the load or centre of gravity is being computed. In one embodiment (Fig. 1, not shown), a ring potentiometer forms one junction of the load and moment resistors and the positioning of the slider to balance the bridge simultaneously positions a pointer to indicate load or position of the centre of gravity. In a further embodiment, Fig. 3 (not shown), two ratiometers are used, one indicating weight and the other the position of the centre of gravity, the double pole switch is thereby dispensed with.

Title: Improvements in the printing of posters and other large sheets by photo-mechanical processes
IPC: G03F7/14
Filed: 1926-08-04
Abstract: 279,186. Entwistle, H., and Entwistle, W. Aug. 4, 1926. Photo-mechanical printing-surfaces. - Monochrome or multicolour prints in tone, or line, or both, are produced from a gelatin printing layer prepared by making a photographic transparency of the original, and producing therefrom by projection a print which when placed in contact with a composition of gelatin and ferrous salts will produce therein a differentially-hardened gelatin image. The process is particularly applicable to the production of large posters &c. without the use of large printing-blocks. A negative of small size, in grain or half-tone, may first be made from the object to be reproduced if this is, for example, a photograph or wash drawing, and from this negative a positive enlargement is made by projection upon a sensitized surface on a transparent or translucent support. Alternatively, a screen enlargement may be produced from an ordinary negative. From this positive, prints are made on paper sensitized with ferro-prussiate or other ferric, chromic or like salts, and these are placed, without developing or fixing, each in contact with a layer containing gelatin and ferrous or like salts, as in the known " true to scale " process. By such contact the gelatin layer is hardened at the parts in contact with the unreduced portions of the ferro-prussiate or like print, but unaltered at the parts in contact with the reduced portions. When the differentiallyhardened layer is rolled up with ink, the hardened parts accept the ink while the unhardened parts reject it, and prints may be taken therefrom upon paper by transfer under pressure. Where many prints are required transfer ink may be used in the known manner. If prints in two or more colours are required, separate printing-layers are made for each colour from a set of colour-record negatives produced in known manner, and prints are made therefrom in registered superimposition on one sheet of paper &c. Prints exhibiting composite features, such as flat tones and half tones may similarly be produced by separate superimposed printings. The negative employed in making the enlargement may be produced by first making from the original a small photoengraved block in the ordinary way on zinc, copper, &c. by the use of a ruled screen. The interstices in the grain of the block are filled with a white pigment such as magnesium carbonate, and the negative is made from the block as by the wet collodion process. In the production of posters &c. from letterpress or from drawings &c. in line, dot or stipple or in flat tones, an ordinary negative is used instead of a negative in half-tone or grain.

[Also in Group XXXV] In a sound and motion picture projector the rate of feeding of the film 2 through the picture gate 3 is controlled by a loop 12 of the film between the picture gate 3 and a take-up roller 6 associated with the sound scanning device. The film 2 is fed step by step through the picture gate 3 by a claw mechanism 4, and is drawn at constant speed over rollers 13 and 6 provided with pressure rollers 15 and 10, respectively. The motor 30, Fig. 2, is arranged to initially drive the film at too high a speed so that the loop 12 tends to increase in length, and when this happens the curved end of a switch lever 16 is pressed downwardly and breaks contacts 20, 22 so that section 32 of a regulating resistance is brought into circuit to reduce the speed of the motor 30. In the event of the speed being still too fast, a pair of spring-loaded contacts 21, 23 become separated and remove a short circuit across a further section 31 of the regulating resistance. The value of resistance section 32 is manually adjustable by means of a blade 26, and the instant at which the contacts 21, 23 separate may be preset by means of a screw 25. The apparatus is described with reference to magnetic sound reproduction and Fig. 3 (not shown) illustrates the layout of the apparatus.
