Patent GB-740021-A (GB)
Title: Improvements in or relating to circuits for producing pulses
IPC: H03K3/16
Filed: 1953-11-25
Abstract: 740,021. Pulse generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 25, 1953 [Nov. 28, 1952], No. 32724/53. Class 40(6). A pulse generating circuit comprises a pulse generator from which a positive voltage step is derived and applied to the control electrode of an amplifier which has a reflecting delay line in its output circuit so that after a time interval equal to twice the transit time of the delay line the voltage step is terminated. Fig. 1 shows a pulse generator comprising a multivibrator 1, 2 and an amplifying valve 12 having a shortcircuited delay line 14 connected across its cathode load resistor 13 which matches the characteristic impedance of the line. When the multivibrator is in the state when valve 2 is cut off a positive step voltage is applied to the amplifier stage 12 and thus across resistor 13. After a time equal to twice the one-way transit time of delay line 14 a negative step voltage is reflected back across resistor 13 to render valve 12 heavily conducting so that its grid/cathode circuit presents a low impedance compared with resistor 8 and a voltage drop is produced at the anode of valve 2. This drop in voltage cuts-off valve 1 and renders valve 2 conductive, the resulting fall in its anode voltage terminating the initial positive step-voltage across resistor 13. Thus a curbed pulse is produced across resistor 13, Fig. 2 (B), not shown, which if differentiated provides two positive pulses separated by a period equal to twice the oneway transit time of delay line 14. The valves 1, 2 and 12 may be replaced by transistors, in the case of the amplifier stage, the emitter collector and base electrodes corresponding to the cathode, anode and control-electrodes respectively. In a modification shown in Fig. 3 the multivibrator circuit of Fig. 1 is replaced by the grids 16 and 17 of pentode 15 connected as a blocking oscillator and the oscillatory effect is controlled by the amplifier 25 being connected to the suppressor grid of pentode 15. The delay line 30 is in this case open-circuited at its distant end so that pulses are reflected without reversal of polarity. In a further modification the multivibrator circuit comprises a triode and pentode valve, the amplifier stage controlling the multivibrator by connection to its suppressor grid.

Abstract: 1475588 Driving printing machines HARRIS CORP 26 July 1974 [1 Aug 1973] 33222/74 Heading B6C A printing press has two co-acting blanket cylinders 20, 22, each having a plate cylinder 16, 18 associated therewith, the cylinders each having bearing rings 26, 28 in rolling contact when the cylinders are in contact, and being driven by drive train 30. Gears 34 and 36 are rigidly attached to blanket cylinder drive shafts 38 and 40, and are in mesh both where the cylinders are in contact or when they are tripped. The plate cylinders are driven from these gears via gear wheels 44, 46 and devices 48, 50 which allow circumferential adjustment, e.g. harmonic drive units. The plate cylinder gears are also arranged to be in mesh when the plate and blanket cylinders are separated, and when they are together. To achieve this, non-standard gear wheels may be used, so that the pitch diameter is greater than would be expected for a standard gear. This leads to a discrepancy between the number of teeth on the co-acting gear wheels to achieve equal surface speeds of the plate and blanket cylinders, and this is compensated by the gearing within units 48, 50.
