IPC: H03B19/16
Filed: 1964-01-22
Abstract: 982,065. Frequency changing. PATELHOLD PATENTVERWERTUNGS - ELECTROHOLDING A.G. Jan. 22, 1964 [Feb. 22, 1963], No. 2759/64. Heading H2F. A frequency multiplier comprises a capacity diode 5 (whose bias is not shown) fed from an input supply G at frequency f 1  through an input circuit 1 (L<SP>1</SP> 1 , L<SP>11</SP> 1 , C 1 ) tuned to the frequency f 1  and connected to a load Ra through an output circuit 4 (L<SP>1</SP> 4 , L<SP>11</SP> 4 , C 4 ) tuned to a harmonic frequency nf 1 , say 4f 1 , and includes circuits 2 and 3. The circuit 2 (L 2 , C 2 ) forms with the circuit 1 a series tuned circuit tuned to the frequency of an unwanted or false harmonic (say 3f 1 ) providing at this frequency a minimum impedance and hence an effective short circuit for the diode. Similarly, the circuit 3 forms with the circuit 4 a series tuned circuit tuned to another unwanted harmonic (say 2f 1 ) thus providing minimum impedence for this frequency. The arrangement allows the multiplier to behave in an optimum fashion. If the multiplier were a tripler both series circuits would be tuned to 2f 1 . As shown, the circuits 2 and 3 are parallel L.C. circuits tuned to the output and input frequencies respectively. In modifications (Figs. 4, 6 and 7, not shown), the circuits 2 and 3 are replaced by inductances, an inductance and capacitance and series L.C. circuits respectively. In a further modification, Fig. 8, an intermediate circuit transformer is provided which comprises a circuit L 4 , C 4  tuned to the output frequency nf 1 , a primary coupling winding L 3  and a secondary coupling winding L 5 . Seen from the diode the circuit forms a series resonant circuit at the unwanted frequency 2f 1 , this circuit being formed by the capacitance of L 1 , C 1  and the inductance L 3 . Fig. 9 (not shown) discloses a rearrangement with a series capacity diode, and Fig. 10 (not shown) discloses two circuits as in Fig. 1 connected together to give an output of n<SP>2</SP>f 1 .

Filed: 1974-01-22
Abstract: 1419903 Drying painted metal strip HUNTER ENG CO Inc 22 Jan 1974 02973/74 Heading F4G A closed loop, inert atmosphere, paint line oven assembly for evaporating paint solvent from painted metal strip 16 comprises an enclosed oven 10 through which, in use, the painted strip 16 passes, a heat source 12 comprising an enclosure 60 having means, e.g. burners 64 or electric arc, therein for generating heat, an intake conduit 40 connected into the enclosure 60 downstream of the heat generating means and a blower 28 having an intake duct 32 and an outlet duct 26, the outlet duct 26 discharging into the oven 10 and the intake duct including a first branch 34 connected to the oven 10 and a second branch connected to the intake conduit 40. A discharge duct 70 is connected at one end to the blower outlet 26 and at the other end to the enclosure 60 upstream of the heat generating means. A valve 72 is provided for deflecting a portion of the blower output into the discharge duct 70 whereby a portion of the oven atmosphere laden with solvent vapour is exhausted through the discharge duct into the enclosure. Means are associated with the enclosure for introducing a quantity of fresh air into the interior thereof, which quantity, in use of the oven assembly, is just sufficient to combine with the solvent vapour and cause combustion thereof. Heat exchange means 38, 50 are mounted in the intake conduit for removing heat, if required, from the hot gas drawn from the enclosure 60. As shown the heat exchange means comprises a coil of pipe 50 containing flowing water, the flow being under the control of a valve 56 which is in turn controlled by the output of a thermocouple 58 in the intake conduit downstream of the heat exchange means. The heat exchange means may comprise an air cooled radiator. A valve 42 in the intake conduit is controlled by the output of a thermocouple 46 in the oven. More air then as required for combustion of the burners 64 is passed therethrough so as to allow the solvent in the circulating gas to completely burn. In a modification (Fig. 2, not shown) a separate burner for burning the solvent vapour is mounted in the enclosure upstream of the heat generating means. The output of the heat generating means is controlled by the output of a thermocouple placed in the enclosure downstream of the heat generating means. Since the gas leaving the enclosure is at a constant temperature a fixed amount of heat has to be taken therefrom by the heat exchange means and thus the valve controlling the flow through the heat exchange means is manually controlled as the setting thereof during a run of the oven assembly is fixed depending upon the temperature of the cooling fluid. A valve in the discharge duct is controlled by the output of a thermocouple placed between the solvent burner and the heat generating means.

Title: Riveting or clinching machines
IPC: B21J15/26
Filed: 1937-02-04
Abstract: 490,012. Eyeleting; riveting. FAIRBROTHER, H. (Tomkins-Johnson Co.) Feb. 4, 1937, No. 3364. [Class 43] [Also in Group XXII] In a riveting or clinching machine for upsetting the heads of clinch nuts or forming a head on rivets a reciprocating carriage 7 conveys the rivets or clinchable members one by one to an anvil 8 where a ram transfers the rivets &c. from the carriage to the anvil by performing a movement relative to the carriage. As shown, the ram 28 is supported and slides on the carriage, and is resiliently connected thereto: When the ram and carriage, carrying a clinch nut 24, are pushed to the dotted line position by a piston-rod 60, and the leading edge of the carriage butts against the anvil, the ram continues its forward movement against the pressure of a spring 79 and pushes the nut off the carriage, the nut being pressed into a recess 107 in the anvil by a spring-pressed lever 58 pivoted on the ram. The clinch nuts are fed from an inclined hopper 6, intermittently rotated by a detent operated by cam 43 and spring, down a shoot and on to the carriage ; the cam 43 is continuously rotated by a pulley 5 from an electric motor. In operation, the spring- raised treadle 110 and rod 111 are depressed once, whereby a clutch is engaged with the pulley 5 and a shaft 113 is given one complete revolution whereby a toggle (not shown) is operated to reciprocate the die 9 which turns over the edges of a nut inserted in a hole in, e.g. a sheet metal plate, and rises, allowing the operator to remove the plate. By this time a protuberance rotating with the shaft 113 has opened a valve which starts a sequence of compressed-air movements which results in movement of the carriage-ram assembly forward and deposition of the nut on the anvil. On its forward movement the assembly strikes an exhausting valve 105 which, via compressedair mechanism, returns the piston 60 to the right. The returning lever 58 first pushes upwards a roller 81 with its rod 84 and hence a clinch-nut-retaining pin 97, and, on further backward movement, abuts a fixed roller 82, the pin 57 being thus raised and a nut, pushed by the weight of the other nuts in the shoot, sliding on to the carriage where it is restrained by a resilient stop 56. Fig. 12 shows a safety device. Only when the ram 28 is in its fully retracted position, so that a bell-crank lever 127 is rotated clockwise from the position shown, is it possible to depress the rod 111, since normally a collar, 130, Fig. 3, on the rod 111 engages the lever 127.
