Title: Mechanism for advancing tape in a stamping machine used to decorat  objects
IPC: B65C9/18
Filed: 1970-05-04
Abstract: 1306688 Ornamenting R WARSAGER 4 May 1970 [27 March 1970] 21448/70 Heading B6G A mechanism for advancing tape used in a stamping machine for decorating articles comprises a cylinder adapted to receive a pressurized fluid therein, a piston reciprocably mounted in the cylinder, a piston-rod fixed to one end of the piston and extending beyond the confines of the cylinder, means for gripping the tape mounted adjacent the cylinder and connecting means between the piston-rod and the gripping means for moving the gripping means when the piston is reciprocated in one direction. As shown in Figs. 1 and 2 platform 19 is constrained to move in a vertical direction only and is moved up and down by the action of air cylinder 17. Mounted on top of the platform is a housing 23. An arm 24 which can be in the form of a mandrel is rotatably secured to the housing 23. The object 25 to be decorated is placed on the mandrel 24 such that it can be either rotated or held stationary thereon. Transfer tape 27 is fed from a reel 26 around guides 28, between the object 25 and a die 30 and then fed between a pair of pull rollers 29 having surfaces which will grip the tape. Rotation of one or both of the rollers causes the tape to be advanced. The die 30 is fixed to a carriage 31 freely slidable on guiderails 32 under the influence of air cylinder 34. Air cylinder 34 is mounted on the stamping machine. The piston-rod 39 fixed to the piston of the air cylinder 34 is pivotably joined to a lever 40 which is joined to a pull roller 29 through a one-way clutch arrangement. Alternatively the air cylinder 34 drives a rack gear connected to the piston-rod 39, the rack gear meshing with a pinion gear 49 clutched to the pull roller 29 (Fig. 5, not shown). When the air cylinder 34 receives air under pressure, the pull roller 29 is thereby caused to rotate and the tape 27 advanced. As shown in Fig. 3 the platform 19 may have a finger 42 thereon which actuates a switch 43 thereby completing an electrical circuit which feeds current to a solenoid air valve 44 which permits air to pass into air hose 47 and thence into air cylinder 34. The pistonrod 39 is moved upwardly and the lever 40 rotates the pull roller 29 and thereby advances the tape. The solenoid is again actuated by a timer and air under pressure enters air line 46 and forces the piston in the cylinder 34 to. its original lower position. Since the lever is connected to the pull rollers 29 through a. one-way clutch the rollers do not rotate in the,opposition direction.

Filed: 1954-07-23
Abstract: 771,929. Valve amplifying circuits; valve oscillators. COLLINS RADIO CO. July 23, 1954 [July 23, 1953], No. 21580/54. Class 40(6) In an amplifier or oscillator incorporating a tuned circuit, the phase/frequency characteristic is modified by inductively coupling a second tuned circuit, resonant at the same frequency, to the first. As applied to a crystal oscillator in which a first amplifier V6 having a tuned anode circuit 28 is coupled to a second amplifier V5 and any one of a number of piezo crystals 25 can be switched so as to couple together the cathodes of the two amplifiers, a further tuned circuit 30 is coupled to the first 28 by mutual inductance: an electrostatic screen 29 prevents capacitive coupling. The inductances L7, 8 of the respective tuned circuits may be re-adjusted for resonance conjointly with the switching of the crystals 25. The arrangement prevents "pulling" of the crystal frequency by the tuned circuit.

Filed: 1920-07-20
Abstract: 149,337. Scherler, W. July 22, 1919, [Convention date]. Marking-action.-For recording the movements of measuring instruments the curves are drawn to a small scale for subsequent optical magnification, the curves being drawn by a hard pin with a fine point to remove an almost opaque and very thin uniform layer from a smooth transparent backing surface to which it adheres, both the thin layer and the backing surface being of material having physical properties of a permanent character and unaffected by normal variations of light, temperature and humidity. The pin may be, for instance, a diamond fragment or an iridium point, and the recording surface consists of a layer of silver on glass. The curve may be scratched in lines placed one after the other so arranged that, when one is formed, the corresponding positions of the pin and recording surface can be changed to bring the pin at the beginning of a new line. The arrangement according to the invention is designed to provide for the economical use of the recording surface and a small mass of the moving parts of the recording instruments.

Abstract: 316,223. American Piano Co., (Assignees of Hickman, C. N.). July 25, 1928, [Convention date]. Pianoforte actions. - A knuckle action for a grand pianoforte comprises a driver 6 carried on a fixed pivot 5, a hammer 8 pivoted to the driver at 7, an upper knuckle-link 11 pivoted to the driver at 10, and a lower knuckle-link 13 pivoted to the upper link at 12 and to the key at 15. In the normal position of rest, the pivot 12 is forward of the line 10, 15, and on depression of the key an upward thrust is given, through the adjustable capstan 18 and spring clip 17, to the links 13, 11 and so to the driver 6 and hammer 8. Before the hammer strikes the string, an adjustable screw 27 on an arm 6<a> of the driver 6 breaks the knuckle and immediately thereafter an adjustable screw 23 contacting with a rail 21 stops the driver 6. The hammer rebounds from the string against the arm 40 of the driver 6, carrying the driver down and still further breaking the knuckle, until the hammer engages the backcheck 39. On release of the key, causing the check 39 to be withdrawn downwards from the hammer, the repetition-spring 24 (which is adjustable) slightly raises the driver and hammer and then thrusts the knuckle-links 11, 13 into normal position, the key (preferably weighted at its rear end) pulling the parts to their original positions.
