Title: Data printing systems for optically printing variable data on output documents
Inventor: STILLWELL PETER FREDERICK THOM
IPC: G06K15/12
Filed: 1961-08-08
Abstract: 1,055,871. Photographic typecomposing. RANK ORGANIZATION Ltd. Nov. 8, 1962 [Aug. 8, 1961], No. 28608/61. Heading B6W. [Also in Division G2] Apparatus for printing variable data in appropriately distributed form on to an output document carrying fixed data, such as an insurance policy, from a data-bearing medium on which said variable data is permanently recorded in undistributed form, i.e. with symbols or characters in different relative positions from those that they assume on the output document, comprises optical printing means for printing said variable data on to said output document by the formation by radiation of a latent developable or visible image of the variable data, and sensing means responsive to control markings on said output document indicating the position of said fixed data so as to print the variable data in the desired relationship with the fixed data. As described, the variable data is recorded on a photographic film in undistributed form from a display of symbols, e.g. alpha-numeric, produced in response to input signals from a computer device on a cathode-ray tube somewhat as in Specification 926,731 but without the vertical and horizontal address controls described therein. The display is recorded in horizontal lines either on a continuously running microfilm, provision being made in the display for correcting for slant which would be caused by film movement, or on intermittently moving film, " line feed/carriage return," " vertical tabulating," " form feed " and " change form " code marks also being recorded on the film. These timing marks may be applied to the microfilm by means of a suitable triggered flash tube and co-operating mask instead of the cathoderay tube if the microfilm is moved step-wise. The film produced is then fed intermittently a line at a time and used to print from the information on the film a line at a time by flash exposure of a continuously rotating xerographic drum, the powder-developed images being transferred on to the output document (Fig. 5, not shown). Printing in correct position on the output document of the recorded data is effected by the output document bearing photo-electrically sensed fixed data line-indicating marks controlling a memory device so that the timing marks on the film control via photo-electric sensing means its intermittent feeding and flash illumination at appropriate instants.

Title: Method and apparatus for handling hosiery
IPC: D06H3/16
Filed: 1956-09-20
Abstract: 829,761. Inspecting hosiery. ALAMANCE INDUSTRIES Inc. Sept. 20, 1956 [June 6, 1956], No. 28737/56. Class 42 (2). Apparatus for inspecting stockings, Fig. 1, stitched together toe to welt in a chain and for automatically severing the stitching between successive stockings comprises a rotatable inspection form 8 on to which successive stockings are drawn for inspection, a supporting guide 12 through which the stockings are drawn on to the form and a severing mechanism 15 by which the stitching connecting the toe of a stocking on the form to the welt of the next stocking in the chain is automatically severed. The severing mechanism consists of an electrically operated clipper carried by a vertically reciprocatory rod 17 actuated by a lever 24 and a link 23 from a solenoid 21 which is energized simultaneously with the clipper when a switch 38 is closed by one of a pair of cams 42 in consequence of the rotation of the form 8 by the operator. A spring 31 counter-balances the mechanism for raising and lowering the clipper while a spring 32 cushions the downward movement. Upward movement is limited by a collar 30 and a pin 26 rides between spaced guides 29 to prevent rotation of the clipper. After inspection, the stocking is withdrawn and turned by suction from the form 8 through the open end thereof and a tube 10 and deposited upon a stacking platform 11. A pair of scissors or shears 46, Fig. 10, may be used instead of the clippers 15. The shears are mounted on a piston rod 54 reciprocated under the control of a valve which is in turn controlled by a solenoid and the switch 38. As the shears are raised to operative position, pins 58 pass out of engagement with cams 60 and springs 57 close the blades while on the downward movement the blades are opened by a plate 63 which separates the pins 58 until they move past pivoted fingers 67. In a further construction, severing is effected by an electrically heated resistance wire reciprocated horizontally by a spring-loaded solenoid controlled by the switch 38. Specification 829,762 is referred to.

Title: Improvements in or relating to a method of and means for grinding rollers or the like
IPC: B24B5/26
Filed: 1920-10-15
Abstract: 152,604. Aktiebolaget Svenska Kullagerfabriken. Oct. 16, 1919, [Convention date]. Rollers, treating.-The lateral surfaces of rollers &c. having arcuate generatrices are ground by effecting between the rollers 3 and the grinding- surface of a grinding-disk 1, relative movement comprising in part a swinging movement about the centre O of the generating arc and in part rotation about an axis passing through that centre. These movements are attained by setting the axis of the rotating grinding-disk 1 at an angle to the axis of rotation of the roller cage 4, the point of intersection of these axes coinciding with the point 0; the grinding-surface is spherical, and maintains its form in spite of wear. The rollers are so mounted in the cage that during grinding they rotate on their axes 6. To obtain rollers symmetrical with respect to their transverse middle planes, the rollers are situated in the cage so that these planes all meet at the point 0, as shown in Fig. 2, which shows the arrangement for producing rollers with concave surfaces. To obtain unsymmetrical rollers, the point of intersection of the transverse middle planes is situated at a distance from the point 0; this point is shown at a in Fig. 1, which illustrates the arrangement for rollers with convex surfaces. The speed of rotation of the cage is preferably lower than that of the grinding-disk. In a modification, the grinding-disk may be stationary, and the roller cage rotated about its own axis as well as about that of the grinding-disk. Specification 150,686 is referred to.

Abstract: 404,914. Photographic roll-film cameras. KNIGHT, F. G., Rodney Hotel, Cheltenham. May 2, 1933, No. 29546. Divided on 400,983. [Class 98 (i).] In order that the film may be used for making a larger number of exposures than are to be obtained by using the numbers on the film backing-strip, the film winding- handle a is fixed to a casing b connected to an axially - slidable spool key by a oneway clutch, such as a pawl d on the casing engaging a ratchet wheel e on the key. The casing bears an arrow g co-operating with a circular scale on the camera wall x. For making the first exposure, the handle a is turned clockwise until the numeral 1 on the film backing-strip appears in the usual red window. For subsequent exposures, the handle is first turned counter-clockwise to register the arrow g on the casing b with the arrow f on the scale ; it is then turned clockwise through one complete revolution, and then, still clockwise, through part of a revolution to bring the arrow g opposite the scale number corresponding to the film section to be exposed. The drawing shows a scale permitting 12 exposures to be made on an ordinary 8-exposure film.
