IPC: G07F17/26
Filed: 1969-07-16
Abstract: 1280348 Selective embossing K TAKEBE 16 July 1969 35929/69 Heading B6F A machine for stamping indicia in medals includes a disc 13 having holes 58 therein for receiving a fingertip, a required stamp 26 being selected by rotating the disc until the fingertip strikes a stop 57 which moves slightly to initiate operation of an electromagnetically powered hammer 35. A medal is placed in a receiver 16 wherein it is firmly located by a rubber ring 68. Engagement of the stop 57 by a finger pivots a hook (54, Fig. 3) into engagement with a stamp 26 to locate the required stamp accurately beneath the hammer 35, and causes operation of a switch (93) whereby the electromagnet (36, Figs. 3, 4) driving the electromagnet is energized. Simultaneously a second electromagnet (79, Fig. 5) is energized, to pre-set letter spacing mechanism. The hammer 35 operates a switch (94, Figs. 3, 4) during its impression movement, to de-energize the electromagnets (36, 79) to permit the return of the hammer and to allow a pawl (72, Fig. 5) to rotate a ratchet wheel 71 one step. The ratchet wheel 71 is fixed to a shaft 69 bearing the medal receiver 16 to position the medal ready for a subsequent impression. When the required impressions have been made on the medal, a switch (100, Fig. 1) is closed, whereby an electromagnet 90 is energized to eject the medal from the receiver 16 through a plunger 86, 87. A member 98 fixed to the core of the electromagnet 90 operates a switch 96 whereby the machine is switched off. The machine may be coin operated, a stop (44, Fig. 3) being positioned between stamps (26) to prevent operation of the machine until a coin is inserted.

Abstract: 1,127,055. Measuring carbon content of ore electrically. UNITED STATES STEEL CORP. Aug. 11, 1966 [Aug.26, 1965], No.36052/66. Heading G1N. The quantity of carbon removed during the refining of a bath of iron ore in a fuel-fired furnace is determined by measuring the difference between the carbon input to and output from the furnace. The carbon input is determined by positioning a first potentiometer slider 6 in accordance with the mass flow-rate of fuel, followed by a second potentiometer slider 16 positioned in accordance with the predetermined percentage of carbon content of the fuel. Thus the signal at 16 represents the rate of carbon input to the furnace via the fuel. The carbon output is determined by positioning a potentiometer slider 22 in accordance with the percentage of CO 2  in the waste gas, the potentiometer 24 being fed with a voltage derived from a transducer 27 measuring the mass rate of flow of waste gas and modifying this voltage by variable resistors 25, 26 so that the signal at slider 22 represents mass rate of carbon leaving the furnace via waste gas. The difference between the signals on sliders 16, 22 is obtained at 31, representing the rate of carbon removal from the iron ore and is integrated at 32. A divider 34 is fed with this signal and a voltage preset at 33 representing the initial weight of the iron ore charge, whereby the output signal from 34 is proportional to the percentage of carbon removed from the bath. This is subtracted at 36 from a preset signal at 35 representing the initial percentage of carbon in the charge, obtained e.g. by chemical analysis, giving a voltage representing the percentage of carbon remaining in the bath. The measurements made also enable the weight of metal in the bath to be calculated.

Abstract: 831,584. Electromagnetic one-way clutches. REGIE NATIONALE DES USINES RENAULT. Nov. 25, 1957 [Dec. 7, 1956; Feb. 26, 1957], No. 36666/57. Class 80 (2). [Also in GroupXXXIV] In an electromagnetic clutch providing release, one-way and two-way drives, movement of one element relative to the member carrying it controls a switch in the energizing circuit to provide the one-way drive, a by-pass to the switch providing two-way drive. A rotating shaft 1 has splines on which are carried a hub 3 and armature 4 which is co-operable with a yoke 5 and field coils 6 which are journalled at 10 in a casing 2. Current can be fed to the coil 6 through a terminal 8, the other end of the coil being earthed. A light frictional engagement between the hub 3 and the yoke 5 is provided by pivoted shoes 12 carried on pins 13 rigid with the hub 3, the pivots of the shoes 12 and the springs 15 are so arranged that the shoes are freed from centrifugal effects but provide different driving torques in opposite directions of rotation. A hub 9 of the yoke 5 has rigid therewith a radial arm 11, rotary movement of which is limited with respect to the casing 2 by two stops 2a and 2b. The stop 2b comprises a pushrod 17 operating a switch 19, having contacts 18, 20 in series in the energizing circuit of the coil 6, which circuit includes a supply source 21 and main switch 22. The circuit also includes a by-pass circuit, across the switch 19, comprising a switch 23 and a resistor 24. When the device is used in an application when the casing 2 is driven, the connections to the switch 19 and coil 6 are made by slip-rings. When the shaft is rotating in the direction of the arrow 16 and switch 22 is open, no torque is transmitted to the casing 2 except that due to the light drag of the shoes 12 transmitted through the hub 9 and arm 11 to stop 2a. Closure of switch 22 allows this state to remain, but allows closure of switch 23 to energize the coil 6 through resistor 24 to provide transmission of less than full torque through the coupling to the casing 2. A torque reversal under these conditions causes the arm 11 to close switch 19 to provide full torque transmission to the casing 2. If the shaft 1 is rotated in a direction opposite to the arrow 16 and the switch 23 remains open, closure of switch 19 will result in full torque drive (up to the limits of the coupling) in that direction, and release of the drive in the reverse direction. In modifications, the light drag device 13 may be replaced by a low-torque electromagnetic clutch which may be mounted directly on the shaft 1 or connected to that shaft through a freewheel to provide zero-drag on one-way operation of the main coupling. The second electromagnetic clutch may be switched out of the circuit to the same end.
