Title: Improvements in circuits for counting electrical pulses
IPC: H03K3/14
Filed: 1948-10-05
Abstract: 657,132. Pulse frequency dividing circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 5, 1948, No. 25942. Convention date, Oct. 8, 1947. [Class 40 (vi)] In a pulse frequency dividing or counting circuit the incoming pulses are fed to a pulse generator which generates pulses having a repetition frequency which varies with the grid bias voltage of a valve included in the generator, the output of the generator is applied to a filter network to select a higher harmonic of the pulse repetition frequency and the rectified output of the filter is applied as the bias voltage for the valve in the generator circuit. The Figure shows a pulse counting circuit in which the pulse generator comprises a blocking oscillator 1, input pulses being applied at terminals 13, 14 to vary the grid bias of the oscillator and thus the P.R.F. The output from the blocking oscillator is applied via transformer 7 to a narrow band filter 8 which selects for example the thirtieth harmonic of the input frequency which after amplification in valve 9 and rectification by valve 10 charges up capacitor 11. The voltage across capacitor 11 is applied as positive bias to valve 1 to vary the P.R.F. of the blocking oscillator. The output voltage from filter 8 is proportional to the input pulse repetition frequency and as with increase in the P.R.F. of blocking oscillator 1 the output of filter 8 jumps successively to a lower harmonic of the input frequency the graph of the bias voltage of valve 1 plotted against the voltage across capacitor 11 exhibits a series of steep peaks of increasing amplitude, Fig. 3 (not shown). The voltage developed across capacitor 11 is thus a measure of the number of input pulses applied at terminals 13, 14. The pulses from the blocking oscillator are also applied via a sharply tuned circuit 17 to the grid of a thyratron 16. The circuit 17 is tuned to the frequency which the blocking oscillator acquires when a predetermined number of input pulses have been applied so that when this number of pulses is reached valve 16 conducts to discharge capacitor 11 so that an output pulse is produced across resistor 15 and the cycle is repeated.

Title: Improvements relating to cutting out and like presses
IPC: C14B5/00
Filed: 1921-10-06
Abstract: 190,283. Sandt, J. Oct. 6, 1921. Cutting-out presses.- In platen presses actuated by a depending rod worked by an eccentric, only after the platen has been lowered by treadle action, increased safety is obtained by an adjustment of the point at which the depending rod becomes operative. This is effected by a latch which keeps the depending rod out of action until the required point of descent of the platen is reached. This latch, after cutting operation, immediately comes again into obstructive position so that should the treadle not be released, the machine is prevented from making a second cutting operation. In a modified form of latch, the special trip mechanism brings the platen to its " up " position should the treadle mechanism not be released. The platen 2 carried by the plunger 3 can be lowered by treadle action through a band 12 which passes over a disc 13 on the driving- shaft 14 and is raised by the treadle. This strap raises a lever 10 pivoted at 5 and carrying a wing 21 which bears against a beak 20 on a second lever 6, also pivoted at 5, and having an extension which enters a socket in the plunger, as shown, and depresses it when the lever 10 is raised. The cutting stroke is effected by the rod 23 which is worked by an eccentric on the end of the shaft 14, and presses on a step 24 on the plunger 3. The point in the descent of the plunger at which the rod 23 passes on to the step is determined by the latch 29, seen more clearly in Fig. 1<a>. This is pivoted at 28 and has a nose 31 capable of contact with a stop 32 on the rod 33, and a projection 30 which bears against the rod 23 and normally prevents it from passing on to the step in the plunger. When, however, the nose contacts with the stop 32 the latch is swung to the left and the rod 23, urged by a spring, passes on to the step of the plunger and depresses the platen. The position of the stop 32 is adjustable by the worm 41 and wheel 40 which turn the arm 38 and so raise or depress the rod 33 which is jointed to the arm 38 as shown. The rod 23, in returning upwardly, is pushed off the step by means of a wedge projection upon it which meets a fixed roller. Fig. 4 shows a modified construction, in which the projection 30 mentioned above is represented by a stop 54 on a, spring-held rod 53 in a casing 51 in the plunger. The stop can be adjusted in position by the rod being depressed by an eccentric 58. In this case, the beak 20 on the lever 6, Fig. 1, is tripped after the cutting stroke by a rod 61 carrying a stop 63, which, as the lever 10 is raised, bears against a piece 62 and thus tilts the beak 20.
