Title: Supply circuits for flash tubes
IPC: H05B41/32
Filed: 1971-09-14
Abstract: 1354791 Supply circuits for flash tubes FRANKE & HEIDECKE GmbH 14 Sept 1971 [14 Sept 1970] 42842/71 Heading H2H [Also in Division H3] A supply circuit for a flash tube comprises a main capacitor 1 adapted to discharge into the flash tube, at least one additional capacitor 4 dischargeable into the flash tube via a thyristor 7 and a differentiating circuit 9, 11 which differentiates the difference in the voltages across the capacitors to supply a trigger pulse to the thyristor. When the voltage across the capacitor 1, charged from a terminal 2, reaches a sufficient level, the capacitor discharges rapidly through the flash tube connected to a terminal 6. Assuming the switch 8, which may be mechanically, photoelectrically or electronically controlled, to be closed, the sudden fall in voltage across the capacitor 1 is detected by the differentiating circuit which triggers the thyristor 7. The capacitor 4 is therefore also discharged into the flash tube.

Abstract: 970,410. A.C. motors. W. KOHLHAGEN. Dec. 11, 1961 [Dec. 20, 1960], No. 44194/61. Heading H2A.

In a first embodiment, Fig. 3, a cylindrical rotor has peripheral pole faces of alternate polarity divided into a first group having identical widths and spaced at a pitch p, the same as the stator pitch, and a second group having different pole face widths and spaced at a different pitch. This group comprises poles f1a, f2a and their opposite counterparts f1b, f2b, of which the pairs f1a, f2b and f1b, f2a are of smaller and larger widths, respectively, than the remainder. Alternatively, Figs. 8, 9 (not shown), the two pairs of non-uniform poles may be spaced apart with the larger and smaller poles opposite each other, respectively. In a second embodiment, Figs. 6, 7 (not shown), the two groups contain an equal number of poles, of which the successive pole faces of each series are of progressively larger peripheral widths. In a third embodiment, Fig. 10, the required starting torque is obtained by the use of rotor poles having sloping edges 80.

Title: Microwave stripline resonator
IPC: H01P7/08
Filed: 1974-10-14
Abstract: 1483262 Strip line resonators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Oct 1974 [17 Oct 1973] 44520/74 Heading H1W [Also in Division H3] A microstrip resonator comprises a substrate, a ground plane on one side of the substrate and a line circuit in the form of an open ring on the other. The gap in the ring is narrow compared to the width of the ring which resonates in a half-wave mode. In Fig. 7a, four such ring resonators 47, 48, 49, 50 are shown coupling strip lines 46, 51 so as to provide a directional band-pass filter. Resonator pairs 47, 48 and 49, 50 are electrically coupled whilst the pair 48, 49 is magnetically coupled. The coupling between resonators 47, 50 and the respective lines 46, 51 is also magnetic. Other Figures (not shown) illustrate intermediate orientations affording mixed electric and magnetic coupling. Each of the lines 46, 51 may be coupled to a coupled pair of resonators, respectively 52, 53 and 54, 55. These afford an alternative transmission path for the microwave energy and, by an interference effect, provide a band-stop filter effect to increase the directivity of the arrangement. In the directional coupler of Fig. 7b, lines 56, 57 are mutually coupled to a resonator pair 62, 63 and separately coupled to respective resonator pairs 64, 65 and 66, 67 both spaced by one quarter-wavelength from the first-mentioned pair. A signal applied to port 58 excites odd and even-mode signals in the lines 56, 57, the odd-mode signal being reflected by the resonator pair 62, 63 and the even-mode signal by the resonator pairs 64, 65 and 66, 67. The odd and even-mode reflected signals are differentially combined at port 58 and additively combined at port 60. Thus, signals at the resonant frequency f 0  of the resonator pairs are coupled between ports 58 and 60 and (it can be shown) between ports 59 and 61. The Specification describes two electrically-tuned ring resonators. In the first (Fig. 10a, not shown), the substrate is made of a semi-conductor material and a voltage is applied across it to vary the position of a depletion layer and hence the capacitance of the ring resonator. In the second, Fig. 10b (not shown) a varactor diode 88 connected to the voltage node of the resonator 87 provides the necessary variation in capacitance.

Beyond the second washer 31, rolled threads prevent passage of same. The first washer 30 is assembled on the shank before a groove 35 is rolled by dies 40, 41 (Fig. 13) with bevelled edges 44, 45 of plate 43 forming bounding ridges. As rolling progresses, grooves 46 on dies fade out into plane surfaces, depressing ridge furthest from head back into groove 35. Finally the second washer is assembled on the shank and the threads are rolled. On screwing the terminal into counterpart with head upward, the second washer drops to thread top, leaving space between washers for insertion of spade terminal or wire end. Additional washers may be added before thread rolling.

Apparatus for removing water from the surfaces of articles such as electrical components comprises a sump 1 containing a water-immiscible solvent which is vigorously agitated either mechanically or by boiling. A quiescent region 19 is formed in the sump either by making the sump long and narrow with the heater 2 or agitator at one end, or by providing a baffle 18. The solvent has a specific gravity at 20‹ C. of at least 1À1 so that the water forms a surface layer at 19 and overflows into a separating tank 24. From this tank, water goes to waste through an overflow 27 positioned at a higher level than the weir 31 so that solvent does not overflow. Solvent overflows the weir 31 and is pumped back to the sump 1 through a pipe 22. Vapours in the space 3 above the sump 1 are condensed on tubes 4 and pass to a water separation chamber 8 with a water overflow 10. Solvent from the chamber 8 overflows the weir 14 into the sump 1, or as shown, into a rinse sump 15 with a heater 16. There may also be a second rinse sump. If the solvent forms an azeotrope, the azeotrope must contain not more than 4% water by weight, and its boiling point must be not less than a temperature 8‹ C. below that of the solvent. Suitable solvents include trichloromonofluoromethane, trichlorotrifluoroethane and methylene chloride. A surface reactive agent may be added to the solvent. Suitable agents include long chain alkyl trimethyl ammonium chlorides and bromides, and alkyl phosphate esters neutralized with saturated aliphatic amines.
