Abstract: 1370065 C.R.T. character display INTERNATIONAL BUSINESS MACHINES CORP 19 May 1972 [23 June 1971] 23561/72 Heading H4T Apparatus for displaying on a C.R.T. 11 a line of text (to be printed by means not shown) so that its appearance and legibility may be visually checked by an operator, comprises a register 17 which receives from 13 the characters of the line in turn and during each of a number of column scans for that character controls readout from 19 of the appropriate video bright-up signals. The invention is concerned with the use of a number of column scans related to the point size of the individual character and the varying of this relationship, for example for obtaining compression of certain characters of the character set. Each character has a "standard" number of column scans (i.e. a point size) stored in 31 which is read out and presented to comparator 33; when the count in 55 equals this 33 delivers an output to reset 55 (and 43) and call up the next character from 13. To obtain compression the count in 55 may be inhibited by a signal from 55 to close AND gate 57 for one or more columns to eliminate a blank column at the end of a character, and the manner in which this is done is settable by mode switch S 1 for various type sizes. The output from 19 is transferred to 21 and dynamicized at 23.

Abstract: 1513215 Exposure control FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 10 June 1976 [6 Sept 1975] 24029/76 Heading G2E The light-sensitive element of an exposure control device in a motion picture camera receives light passing through the objective lens by reflection from the shutter and then from another reflecting surface, the second reflective surface being capable of occupying one of two positions according to whether the shutter is rotating or stationary, so that the light falling on the light-sensitive element is generally constant. As shown, light entering lens 1 passes through to the camera aperture 2, being intermittently interrupted by the conical surface 6 of a shutter 4 rotating on a shaft 3. The surface 6 reflects the light beam up to a further mirror 7 which reflects it again to the light-sensitive element 8 which is connected to an exposure metering or control device 9. Thus the beam of light reaching element 8 is also intermittent because of the rotating shutter 4. Mirror 7 is arranged in the centre of a roller 10 connected to a bracket 12, and pivotally mounted on a shaft 11. Bracket 12 is pivoted in opposite senses by springs 14, 15, until either arm 12a or 12b abuts against a stop 13. Spring 15, which is stronger than spring 14, is attached to an over-centre switch 16 actuated by a shutter release 17. When this is no longer pressed, the camera becomes inoperative, with the shutter stationary in the position in which it blocks the light from aperture 2. Since light is now permanently, and not intermittently, reflected from the shutter, the amount of light reaching element 8 would be considerably greater than while the shutter is rotating. To overcome this, the switch 16 changes over as release 17 is set free, so that the force of spring 15 is reduced sufficiently for spring 14 to become operative. Bracket 12 is now drawn clockwise from the position shown in the Figure until arm 12b abuts against stop 13. Mirror 7 thus assumes a different angle, so that not all the light falling on it is reflected to element 8. The amount of such light can be varied by bending the flexible arm 12b.

Abstract: 1470388 Reciprocating pumps RCA CORPORATION 14 May 1974 [21 May 1973]  24140/73 Heading F1A [Also in Divisions B6 F2 and G3] A device, e.g. for controlling fluid-flow, for use as an ink ejector of an ink printer or for use as a fuel injector of an I.C. engine, comprises a tube 30 having at least one bow-shaped wall portion 34a, 34b and a transverse wall 32. On application of a magnetic or electric signal the wall portion 34a, 34b alters its arcuate length and thereby alters the cross-sectional area 35a, 35b. The signal in the present embodiment is an electrical signal applied to a coil 38 wound so as to induce a magnetic flux 33. The coil may be formed by a printed circuit attached to the wall 32. The wall portions 34a, 34b contract when subjected to the flux whereas the wall 32 expands, thereby producing a reduction in the cross-sectional area 35a, 35b. Thus if the device is without a nozzle 36 and is supplied with a D.C. signal it would function to control fluid-flow through the tube 30. However when the device is formed as an ink ejector an A.C. signal is applied to cause ink to be ejected through nozzle opening 39. The wall portions 34a, 34b may be of nickel, nickel-iron alloy, cobalt or cobal-iron alloy, and the wall 32 may be of iron or iron-nickel alloy. The wall 32 may be arcuate. The elliptical tube 30 may be provided with a further transverse wall lying on its minor axis. The tube may instead be of circular, parabolic or hyperbolic cross-section. In an alternative embodiment, Fig. 5 (not shown), the magnetic flux is produced by an electromagnet (50a, 50b). Fig. 6 (not shown) illustrates the application of the device to an ink printer.
