Title: A process for the production of an intaglio printing roller for the reproduction of monochrome or polychrome half-tone copies by photomechanical means for textile printing
IPC: G03F5/20
Filed: 1945-07-11
Abstract: 602,885. Producing photo-mechanical printing rollers. HEBERLEIN & CO., AKT.-GES. July 11, 1945, No. 17694. Convention date, July 21, 1944. Addition to 567,126. Drawings to Specification. [Class 98 (ii)] The process of the parent Specification for producing an intaglio printing roller for the reproduction of monochrome or polychrome half-tone copies by photo-mechanical means for textile-printing is modified in that, by a suitable selection of stops and length of exposure, a screened positive, which is copied on to a light-sensitive etching resist layer on the roller, is produced exhibiting in the shadows white dots corresponding to the requisite supports for the doctor which are initially of sufficient size to avoid breaking out during use, the said positive being retouched in the lighter parts by local weakening to make the tonal values appear correct. The positive may be made either by contact printing from a screened negative obtained by photographing an original through a screen in contact with the film and a circular stop, or by photographing a continuous-tone negative through an out-ofcontact screen and a quadrilateral stop. Instead of correcting the screened positive, the requisite correction of the tone values may be effected by intensifying the screened negative from which the positive is contact printed. If desired, the screened positive may be treated so as to bleach the silver image and tan the gelatine in the parts containing silver.

Abstract: 729,764. Oscillating machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 22, 1953 [July 25, 1952; Nov. 7, 1952], Nos. 18852/62 and 28163/52. Class 35. A magnetic oscillatory device, e.g. for gyroscopic instruments, comprises a soft iron armature having a central stem 11 with two arcuate polepieces 13 and at least one winding 14 surrounding the stem 11, and a permanent magnet comprising a base portion 15 having two arcuate polepieces 16 of opposite polarity surrounding or within the armature pole-pieces 13, there being relative angular movement between the armature and the permanent magnet. The two pole-pieces 16 are separated from each other by two air gaps 17 so that the lines of force from the permanent magnet traversing the winding 14 will depend on the shunting action of the pole-pieces 13, according to the relative position of the latter with respect to the air gaps 17. While Figs. 1, 2 show the pole-pieces 16 on the outside of the pole-pieces 13, the device can be modified whereby the armature stem 11 extends (without touching) through the magnet 15 so that the pole-pieces 13 extend over the outer instead of the inner faces of the pole-pieces 16. In a further modification, two devices as those described above may be combined in one apparatus with two coaxial armatures mounted for rotation as one at opposite sides of a common magnet or a pair of magnets. The magnetic oscillatory device can be used either as a gyroscope torque motor or as generator with a gyroscope to give signals corresponding to the movement of the gyroscope. In some cases the permanent magnet may be replaced by an electromagnet.

Abstract: 1338771 Labelling machine speed control H KRONSEDER 3 June 1971 [22 July 1970] 18889/71 Addition to 1255827 Heading B8F A labelling machine is supplied with articles by a variable speed conveyer 9 and spacing worm 10, and has monitoring switches 12, 13 at inlet and outlet regions which respond to the accumulation of articles to control the speed of the conveyer and operate a path blocking device 15 as described in Specification 1,255,827. Articles are assembled on a collector conveyer 7 which delivers them to conveyer 9 and a further accumulation monitoring switch 11 is mounted on this collector conveyer. Operation of both inlet switches on sensing accumulation causes the blocking device 15 to move from a closed to an open position and the speed of the conveyer to increase to a maximum. Once the accumulation has cleared switches 11, 12 the speed is reduced and the blocking device 15 closes, but in a modified control system speed reduction follows the clearing of switch 11 and the blocking device does not close until switch 12 has been cleared. The switch 13 closes the blocking device 15 and reduces the speed if an accumulation develops at the outlet but a further switch 13a may be provided which initially lowers the speed on sensing the accumulation; the device 15 only closing when the accumulation reaches switch 13. By linking the deflection of switch 11 to the speed control, an infinitely variable adjustment of the throughput rate between the low and high speeds can be effected. In a modification switch 11 is replaced by a series of three switches spaced upstream of switch 12 which must all operate in conjunction with switch 12 to open the blocking device and increase the speed and which provide successive reductions in speed as they become free of the accumulation. Manual controls are provided to operate the blocking device and speed control if required.
