Title: Pulse generator
IPC: H03K7/06
Filed: 1973-03-16
Abstract: 1431056 Pulse generators; voltage controlled oscillators SIEMENS AG 16 March 1973 [16 March 1972] 12890/73 Headings H3T and H4L In a pulse generator of the type in which a sawtooth wave and a control voltage are compared in the comparator and in which the sawtooth is generated by reversing a charging current each time the waveform reaches upper and lower datum levels, the control voltage is limited to values within the sawtooth extremities and the charging supply, the upper and lower datum levels and the limit values are all proportional to a reference value, one at least of the constants of proportionality being zero if required. It is shown that the frequency is thus independent of the reference voltage. As described a Miller integrator 10, 11 is charged from a potentiometer 1 connected to reference voltage supply -U, via a switch 3 until the output voltage reaches an upper datum level applied to a comparator 13, which, in this case, is zero voltage. The narrow pulse from the comparator switches over a bi-stable circuit 16 opening switch 3 and closing switch 8 so that discharge is effected by an equal negative voltage obtained from a unity gain inverter 6, the discharge continuing until a lower datum level derived from -U r  applied to comparator 14 is reached and the charging cycle thus initiated. The resulting triangular wave is applied to a comparator 21 together with a voltage V v  derived from an error signal applied at 25 to a variable gate amplifier 24. The voltage U v  is prevented by diodes 27 and 28 from varying outside limits which are proportional to the reference -U r  which are within the extremes of the triangular wave. Switches 3 and 8 may be field effect transistors and Zener diodes 18, 19 and 22 are limiting diodes.

The dashpot may take the form of a waisted portion of the stem, Fig. 1, or it may take the form of a projection 112 Fig. 4, which enters a recess 140 formed in the piston 128, 134. The valve may be a globe shut-off valve Fig. 1, a flow-diverting valve with two seats 63, 64, Fig. 2, or a sluice shutoff valve, Fig. 4. The valves may be manuallyoperated by a hand wheel 27, and a valve-position indicator 22, 24, 25, Fig. 1, is provided. The portion of the piston chamber above the piston is connected to the main valve chamber 6 by piping 36, 38, and a three-way valve 37, which can be connected to drain 40 and chambers 29, 5 are connected by orifices 51 1 . In operation, water flows through line 72, Fig. 3, flow-diverting valve 71, line 73, heater 70, shut-off valve 75 of the Fig. 2 or Fig. 4 type, and feed pipe 76, the pressure between parts A, B and C of the piston chamber being equal. When it is required to isolate heater 70 due to a tube burst, the rise in water level actuates a switch which automatically vents cocks 80, 81 to drain. The pressure drops in chamber A, valve 71 closes off the main outlet and diverts the flow through by-pass line 77 and valve 75 shuts-off inlet D. During this closure of the valves the dashpots 48, or (140, 112) come into operation. When it is required to open-up the circuit, cocks 80, 81, are shut, allowing pressure to build up in chambers A, valves 37 are actuated so as to connect chambers B to drain, and the piston move the valve closures, the speed of movement being controllable by hand wheels 27. The valve, Fig. 4, comprises throttle valves 162, 172 which are pre-set so that the rate of flow into chamber B is greater than that leaving chamber A. In a modification, the Fig. 1 valve may have several stems placed symmetrically in the piston.

Title: Improvements in or relating to deep drawing presses
Inventor: VASVARI JOZSEF
IPC: B21D24/14
Filed: 1962-04-06
Abstract: 928,260. Cupping. SZERSZAMGEPFEJLESZTO INTEZET. April 6, 1962, No. 13370/62. Class 83 (4). An hydraulic deep drawing press has pistons which exert a rim gripping force on a workpiece, said pistons being operatively associated with a deep drawing piston for movement in a common hydraulic chamber, the arrangement being such that in operation the hydraulic pressure generated in said chamber acts upon said deepdrawing piston and at the same time upon the said first mentioned pistons in order to develop a rim gripping force to act on the workpiece. The deep drawing tool 1 is carried by a piston 9 operating in an hydraulic chamber 8 of the press. Pistons 12 mounted in the chamber 8 and passing through the piston 9 operate a rim gripping disc 2 to press a gripping ring 16 against the rim of a workpiece 15. Oil pressure in chamber 8 acts on all the pistons and oil pressure in a chamber 10 surrounding the pistons 12 acts on a portion of the under-surface of the piston 9 and also on rings 11 accommodated on the pistons 12. Thus the pressure on pistons 12 is increased by the pressure in chamber 10. The oil can leave the chamber 10 via a valve 7 into an oil reservoir 4 via a reversing valve 5. On the return movement of the press the oil fed by a pump 3 flows through the reversed valve 5 and a check valve 6, the chamber 8 being connected to the reservoir via the valve 5. In a modification instead of the valve 7 the oil flow is divided into two branches, one branch having a restricted bore for delivering only high pressure oil and the other branch having means for adjusting its internal cross-section so that the oil pressure can be regulated. When the tool engages the workpiece the adjustable branch is closed so that the pressure in chamber 10 increases strongly as the deep drawing commences and provides a given initial rim gripping force. As the pressure in chamber 8 rises the adjustable means are opened automatically by the increased pressure to allow the oil to flow out of the chamber 10 via the larger adjustable branch to the oil reservoir.
