Abstract: 1,215,309. Shearing. I. UNGERER. 20 Dec., 1967 [24 Dec., 1966]. No. 57917/67. Heading B3W. Flying shears for cutting sheet metal comprises upper and lower cutters 8 and 11 mounted on arms 5 pivotable about fixed bearings 6. The lower cutter carrier 10 is mounted at each end on a guide 9 slidable on each arm 5 and secured to the guides 9 are bearings 12 for eccentrics 4 carried by a drive shaft 3. In operation, the sheet metal passes between the opened cutters until at an electric signal the shaft is connected through a clutch to a drive (neither shown) which rotates the shaft once for each cut. During the rotation the eccentrics rock the arms 5 about bearings 6 and raise the lower cutter carrier 10 until the cutting edges of blades 8 and 11 overlap, Fig. 3 (not shown), and return the arm and carrier 10 to the starting position (Fig. 2, not shown). The speed of the cutters in the feed direction of the sheet metal is adapted to the speed of the sheet metal by selection of the eccentricity of the eccentrics and of the location of the eccentric bearings/guides on the arms 5. In another embodiment the lower cutter is rigidly connected to the arms 5 and the upper cutter is slidable and is associated with the eccentric bearings/guides. In an alternative embodiment the cutters reach cutting position before the arms are vertical.

Filed: 1973-12-18
Abstract: 1451507 Electro-erosion ATELIERS DES CHARMILLES SA 18 Dec 1973 [29 Dec 1972] 58503/73 Heading B3V In an electro erosion process wherein successive trains of voltage pulses are applied by at least one D.C. source 3 across a machining gap defined by an electrode 1 and a workpiece 2, each train of pulses contains at least one discharge having a voltage between the voltage of a normal discharge and the voltage of an abnormal discharge producing an arc or short circuit across the gap 1-2 and the intervals between the successive trains of pulses are controlled to ensure that at least the first discharge of a train is not a discharge having the intermediate voltage. When a discharge is initiated, the voltage across a resistor R 1  is applied to a Schmitt trigger 5 which controls a monostable 6 for determining the discharge duration. The pulse interval is determined by a monostable 7 which is connected to an OR gate 8 connected via an inverter 9 to a switching transistor 4. The voltage across the gap 1-2 is applied to differential amplifiers 10 and 11 which are set so that a normal discharge produces outputs from both amplifiers, an abnormal discharge produces no output from either amplifier and an intermediate discharge having a voltage between a normal and an abnormal discharge, produces an output from the amplifier 11. At a predetermined time after the initiation of the discharge determined by a circuit 15, an output is produced from an AND gate 14 if an intermediate discharge is produced and is applied to an AND gate 17. When the other input of the gate 17 receives a pulse at the end of the discharge, an output pulse is applied to a counter 19 which delivers a pulse to a monostable 16 via an OR gate 20 each time a certain number of pulses is counted whereupon the transistor 4 is switched off via the gate 8 for a longer period to define the end of the pulse train. When the monostable 7 reverts to its stable condition whilst the monostable 16 is unstable, an output from a store 21 is applied to an AND gate 23 which supplies an output signal only during the first pulse of a train. The output signal from the gate 23 is applied to an AND gate 24 which is connected to the gate 14 so that it delivers an output if an intermediate discharge is detected. Hence if the first pulse of a train is an intermediate discharge, the monostable 16 is rendered unstable to produce a longer interval. The instability time of the monostable 16 may be adjusted by circuits 25, 26. In another embodiment (Fig. 3, not shown), the instability times of the monostables 7, 16, and hence the intervals between the pulse trains and the pulses in each train, are modified automatically in accordance with the number of intermediate and normal discharges respectively.

Title: Microwave band filters in wave-guides of circular cross-section

Abstract: 1300073 Band-pass filters TAVKOZLESI KUTATO INTEZET 12 Dec 1969 [20 Dec 1968] 60812/69 Heading H1W A coupled-cavity microwave band-pass filter is formed by a sequence of spaced iris plates 26, 27, 28, and 29 extending across and arranged within a circular waveguide 25 joining two rectangular waveguides 24, the plates having a width of 50 to 80% of the diameter of the circular waveguide and being positioned with their longitudinal axes parallel to the broader or narrower rectangular waveguide wall but with at least one (all, as shown in Fig. 3) parallel to the narrower wall; in the plane of the last-mentioned plate, a pin of metal, powdered iron, or graphite extends with its axis perpendicular to the axis of the sheet, and into at least one of the cavities defined by adjacent plates a parallel pin of metal or dielectric extends. In the filter shown, for the propagation of the TE 11  mode polarized parallel to the narrower wall of the rectangular waveguides 24, the dielectric pins 47, 48, and 49 projecting into the cavities adjust the cavity resonance frequency with respect to that mode. The TE 11  mode polarized in the perpendicular direction, and the TM 01  mode, are suppressed by the use of metal or dielectric pins 40, 41, and 42 projecting into the cavities to adjust the cavity resonance for those modes to a frequency well below the mean frequency of the filter pass band, and by reduction of coupling to those modes by metal pins 30, 31, 32, and 33 which extend in the planes of the plates and by powdered iron or graphite pins 34, 35, 36, and 37 which extend in the planes of the two end plates and both reduce coupling to, and produce loss in, those modes. Coupling between the cavities is adjusted by dielectric pins 43, 44, 45, and 46. Mismatching at the junctions between the circular waveguide 25 and the two rectangular waveguides is reduced by restricting the length of the two end sections of circular waveguide between the junctions and the end plates 26 and 29 to 25 to 50% of the diameter of the circular waveguide, and by reducing the diameter of the latter in those two end sections by the use of metal rings 51 (only one shown in Fig. 3). The various pins are supported in ribs 38, 39, and 50.
