Title: Improvements in nozzles
IPC: B29C48/05
Filed: 1934-09-05
Abstract: <PICT:0426763/IV/1> <PICT:0426763/IV/2> <PICT:0426763/IV/3> In a nozzle device for producing extremely fine threads from cellulose or the like, particularly for use in producing line-screens for colour photography, thin plates a<1>, a<2>, a<3>, advantageously of metal, and in number depending on the number of threads to be formed are laid side by side and secured together to form a block, the plates being provided with holes or perforations b<1>, b<2>, b<3> which coincide in the block to form channels B<1>, B<2>, B<3> passing completely through the block and separate from one another, and a slot c<1>, c<2> or c<3> being formed in each plate extending from one of the holes to the edge d of the plate, the slots in adjacent plates in the block extending from different holes and not overlapping as far as the outlets at the edge of the plates.  The plates have holes e through which bolts f pass, serving with the lateral plates g to press the plates tightly together.  Feed-tubes h supply different solutions to each channel B<1>, B<2> and B<3>, e.g. a red solution to B<1>, a green to B<2> and a blue to B<3>, then the red solution can pass along all the slots c<1> in plates a<1> to the edge d of the block whence it is extruded to form red threads which lie on a support extending beneath the nozzle in proper sequence next to and in contact with green and blue threads which have been formed by the solutions from the channels B<2> and B<3> passing along the slots c<2> and c<3> respectively.  The cross-section of the threads depends on that of the apertures and if these have a height greater than the thickness of the plates, the threads are extruded as rectangles balanced on their narrow sides.  Thin distance plates i may be inserted between the slotted plates a<1>, a<2>, a<3>, these distance plates having holes b<1>, b<2>, b<3>, but no slots, and these may extend a short distance beyond the end of the block to prevent premature contact of the extruded threads which may also be cooled within the reach of the extensions of the distance plates to harden them rapidly. The plates may be stamped from metal or celluloid, and while the slotted plates may be 0,5 mm. thick, the thickness of the distance plates is 0,2 mm. or less.

Title: Data recording system
IPC: G11B5/17
Filed: 1971-04-19
Abstract: 1283016 Recording and playback NATIONAL CASH REGISTER CO 19 April 1971 [15 April 1970] 25843/71 Heading G5R A transducer has a pole with two tip portions 22, 34 which respectively function for recording only, and playback only. In the arrangement shown, a coil 36 is fed binary pulses from a device 38 by a clock enabled AND gate 40, and data is recorded in a conventional manner with poletips 20, 22. The tip 34 monitors the recording by sensing abrupt flux changes at boundaries 44 between bit elements 46, 48 in the tape 28 at the instants when such boundaries pass by; a coil 50 develops corresponding voltages. For timing purposes, the output of the level detector 52 is fed along with a clock pulse output C2 to an AND gate 54, the clockpulses being timed to occur only when the boundaries 44 are in the vicinity of the tip 34 and thereby making the tip 34 and coil 50 only operably effective at such times. The apparatus shown allows signals actually recorded on the tape to be checked with signals applied to the magnetizing coil 36, an error signal L being produced by an AND gate 62 whenever a discrepancy occurs.
