Title: Improvements in or relating to soldering machines for can bodies
IPC: B23K1/16
Filed: 1931-05-23
Abstract: 361,270. Soldering can bodies. CONTINENTAL CAN CO., Inc., 100, East 42nd Street, New York, U.S.A.-(Assignees of Engelman, J. J. ; 4622, West North Avenue, Chicago, U.S.A.) May 23, 1931, No. 15272. Convention date, Jan. 7. [Classes 83 (ii) and 83 (iv).] Soldering-irons.-In a machine for soldering the side seams of can bodies, in which the bodies are passed over a fixed horn and are soldered on the inside of the seam by gas heated soldering-irons mounted in the horn, means are provided for protecting the bodies from the gas jets during the soldering operation. Lacquered printed bodies may thus be soldered without damaging the surface of the bodies. The bodies C, which may be of the shape shown in Fig. 12 or may be cylindrical, are fed by lugs 4 on an endless chain 3 over a horn 2, containing a number of yieldingly mounted irons 13, which rest by gravity on the seam and are provided with adjustable stops 14 and spacer pins 13c. The seam, which is of the lock seam type, may be initially heated by a burner arranged at the entrance end of the horn. Solder is applied to the base 13b of the irons, which have a small area of contact so as to prevent overheating of the body, by a roller 17 rotated by chain gear in a vertically adjustable bath 18. The roller has a helical rib 28, the width of which is less than the distance between successive bodies, and the distance between the turns of which is greater than the length of each body, so that the solder is applied to the irons in the intervals between the soldering of successive bodies. The surface 28a of the roller is inclined so as to engage the tapered edges 13a of the irons and thus raise them during the application of solder thereto. The bath is formed with partitions 21 so as to prevent the solder from being driven by the helical rib to the end of the bath and so to maintain the level of the solder substantially constant. The irons are heated by gas burners 29, the jets of which pass through a slot 36 in the horn and through inclined holes 37 in the irons. In order to protect the bodies during soldering from the heat of the burners a number of shields are traversed in synchronism with the bodies between the gas jets and the bodies. These shields each consist of a number of plates 41 with offset overlapping edges secured to an endless chain 39. The horn may rest on a number of travelling supports 47 mounted on an endless chain.

Abstract: 706,688. Photographically produced intaglio printing surfaces. GRAVURE ENTERPRISES, Inc. June 19, 1950, No. 15311/50. Drawings to Specification. Class 98(2) An intaglio printing member has a surface comprising printing elements forming a half-tone pattern in which the elements are separated in the high-lights and are connected together in the deeper tones, being bridged by lands defining relatively small cells for carrying ink, the depth of the printing elements between the lands and within the cells being substantially uniform, and the lands and surface of the member apart from the printing elements being of the same height so as to form a doctor blade supporting surface. The lands may be arranged in evenly spaced lines at right angles to each other and at an angle to the lines of the halftone pattern for minimizing moire. The half-tone pattern may have about 120 lines per inch, and there may be about 300 lands to the inch, the lands being less than .001 inch in width. For multicolour printing, the half-tone patterns in the printing members for the different colours may be at different angles (e.g. 0 degrees, 30 degrees, 45 degrees, and 60 degrees) for reducing moirÚ to a minimum, and the angle between the lands and the half-tone lines in the various printing members is the same (e.g. 28.6 degrees). In preparing a printing element, a light-sensitive film or plate is exposed to a fine gravure screen having about 300 lines to the inch to produce a latent image thereof, the half-tone printing surface is inked-up with proving ink or other suitable opaque material and an ink print made on the film or plate bearing the latent image, the film is exposed to uniform light, the ink image is removed with benzine or other solvent, the film is developed and fixed, a positive is printed therefrom, an etching resist is prepared from the positive on line tissue, and the resist is applied to a coppercoated cylinder or flat plate, and a printing surface produced using a single etching bath.

Abstract: 1,009,521. Pulse circuits. ELEKTRONIKUS MEROKESZULEKEK GYARA. April 19, 1962, No. 15356/62. Heading H3T. A circuit for generating various waveforms comprises a plurality of mono-stable units, a bi-stable output unit and a signal source, there being switchable transformer couplings between the various units whereby the monostable units control pulse delays and pulse durations and the interconnections of the various units are selectively switchable so as to generate the required output waveform. As shown in Fig. la, timing signals from a source 1 are fed via a pulse shaping stage 2, an amplifier 3 and a coupling transformer Tro to a mono-stable circuit I which provides a delayed step used to trigger a bi-stable multivibrator 14 and a further mono-stable unit II. Bi-stable multivibrator 14 is reset by the trailing edge of the delayed pulse from the mono-stable unit II so that, after amplification in stages 15 . . . 19, positive and negative pulses are emitted, each starting after a delay determined by circuit I and lasting for a period determined by circuit II. Circuits I, II may be conventional monostable multivibrators or, as shown, may comprise a bi-stable multivibrator 4 feeding a sawtooth generator 6 via a cathode follower 5, the bi-stable multivibrator 4 being reset after a delay determined by comparing at 7, 8 the instantaneous value of the sawtooth from 6 with a reference voltage. The system may alternatively be triggered by signals of the form shown applied to stage 2. The coupling transformers Tro . . . Tr2 are switchable by means of mechanical switches or by electron tubes, transistors or biased diodes so as to adapt the system for the generation of other waveforms. Fig. 2a (not shown) relates to the connections of units I, II, III in such a manner as to generate a pair of pulses (Fig. 2b), the first of which is initiated by a trigger pulse and lasts for a period determined by mono-stable unit I, the second of which starts after a period determined by mono-stable unit II and lasts for a further period determined by unit I. Fig. 3a (not shown) shows the interconnections necessary to drive the bi-stable unit III from the mono-stable unit I so as to provide antiphased square waves having half the output frequency of the input waveform. The invention may also be applied to the generation of coded trains of waveforms by selectively altering the interconnections between the coupling transformers by means of electronic switches controlled by appropriate portions of the output waveform.
