Title: Discharge lamp starting arrangement
IPC: H05B41/18
Filed: 1974-03-26
Abstract: 1445291 Control and starting systems for vapour discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 March 1974 [30 Maich 1973] 13431/74 Heading H2H A circuit arrangement for igniting and supplying a gas or vapour discharge lamp having preheatable electrodes comprises an ignition device which includes a transistor which is rendered alternately conductive and non-conductive at a high frequency during the initial part of the igniting process, and a further switching element being provided to assist the ignition process during the remaining part thereof. A gas discharge lamp 5 having preheatable electrodes 3, 4, one end of each of which are connected to A.C. supply terminals 1, 2 respectively, the connection to terminal 1 including an inductive ballast 6. The other ends of the electrodes 3, 4 are connected to the input terminals 7, 8 of a diode bridge 9-12, the output terminals 13, 14 of which are interconnected by a transistor 17 forming part of an ignition device for the lamp 5. A resistor capacitor circuit 19, 20 having a very short time constant is also connected across the bridge output terminals 13, 14 and serves to render, by way of a diac 24, the transistor 17 alternately conductive and non-conductive thereby causing high voltage peaks to occur between the lamp electrodes 3, 4 which causes the initial preheating of the lamp electrodes. As the amplitude of the voltage peaks increases, a neon tube 24 eventually breaks down whereupon a thyristor 23 becomes conductive which causes the transistor 17 to become inoperative and also continues the electrode preheating process. This ignition procedure repeats during each half cycle of the A.C. supply voltage until the lamp 5 ignites whereupon the ignition device is rendered inoperative. A negative temperature coefficient resistor 22 is provided in parallel with the capacitor 24, the function of which is to terminate the ignition process should the lamp fail to ignite within a predetermined period. In a further embodiment the thyristor is connected between the output terminal 13 and the base of the transistor 17 in which case the transistor functions to generate the voltage peaks and also to carry the subsequent preheating current.

Title: Improvements in Disc Harrows.
Inventor: WARNE FREDERICK CHARLES
IPC: A01B21/08
Filed: 1918-08-19
Abstract: 131,438. Warne, F. C. Aug. 19, 1918. Harrows.-A disk harrow comprises a number uf gangs of tools arranged at each side of the main frame, the angular position of these gangs relatively to the main frame being adjustable by means operable by the forward draft on the implement. The main frame consists of a draft bar 1, yoke 2, and stub-pole 3, gangs of disk harrows 4, 11 being connected to the draft bar 1 by links 5 and 16 respectively. Each gang of harrows has a common shaft and is provided with a strengthening frame which carries .scrapers to clean the disks The links 5 are provided with guides and are assisted by links 8 extending to the strengthening frames of the gangs. The blocks to which the links 16 are secured are adjustable on the bar 1, and play is provided between the links and the blocks to permit the implement to turn corners. The rear gangs 11 are connected by a stretched frame 13. The links 5 are pivoted to the forward gangs and the links 16 to the rear gangs towards the outer and the inner ends of these gangs respectively. A movable draft block 18 is fitted in the stub-pole 3 and is connected through a bar 19 with the tractor draft loop 20. A lost-motion connexion is provided between the block 18 and the bar 19 to permit slight rearward movement of the tractor. The block 18 is connected with the inner ends of the front gangs and the outer ends of the rear gangs by links 29, 30 respectively. The block 18 is connected to the stub pole 3 through a rack 20<a> formed on the side of the loop 20 with which gears a pinion 24 on a shaft 21 supported in blocks 23 carried by the stub-pole 3. The shaft 21 may be turned by a hand-wheel 22 operable by an attendant on the tractor, thus causing the block 18 to move relatively to the main frame and thus varying the angular position of the gangs. The hand-wheel 22 may be locked in any desired position by a spring catch 27<b> engaging a rack formed on the hub of the wheel. When the implement is in motion and the catch 27<b> is released, the main frame tends to move rearwardly relatively to the head 18, thus causing the gangs to take up a non-operative position at right-angles to the line of draft.

Title: Improvements in band-pass filters
IPC: H03H7/01
Filed: 1936-05-13
Abstract: 462,874. Impedance networks. HAZELTINE CORPORATION. May 13, 1936, No. 13544. Convention date, June 10, 1935. [Class 40 (iii)] A composite band-pass filter comprises a plurality of individual filters passing contiguous frequency ranges, each filter terminating in a half-section having a constant-k image impedance at its non- terminal end, and each having one frequency of infinite attenuation in one of the adjacent ranges. Each filter also has a reactance arm which resonates at this frequency of infinite attenuation, the reactance arm of each filter constituting part of the filter passing the adjacent range. The invention is applied to coupling an aerial 10a, 10b, Fig. 1, to a tuning circuit 13. The aerial acts as a dipole for high radio frequencies and as a flat top aerial for lower radio frequencies, so that its impedance is as shown in Fig. 7A. The filter 11a Fig. 1, passes the higher range and the filter 11b passes the lower range. The filter 11a is developed from a constant-k half section A, Fig. 4A, coupled to a terminating half section B, having impedances as shown in Figs. 7B, 8A respectively. These two sections are developed through their equivalent forms of Figs. 4B, 4C to the form of Fig. 4D. Similarly, the filter 11b, Fig. 1, is developed from constant-k half section A, Fig. 5A, a terminating half section B and a section E equivalent to a transformer. The impedances of the sections A, B are as shown in Figs. 7D, 8B. These three sections are developed through their equivalent forms of Figs. 5B, 5C to the form of Fig. 5D. The input impedances of the filters of Figs. 4D, 5D, when combined approximate to the impedance of the aerial circuit. The two output impedances combine to give an approximate uniform impedance over the whole range, Fig. 8C, and are approximately independent of the circuit elements 28, 29, Fig. 4D and 56a, 56b, 55a, 55b, Fig. 5D. These elements are therefore modified to allow the two terminal sections to be combined as in Fig. 6. For this purpose, the circuit 28, 29, Fig. 4D, is tuned to resonate within the pass-range of the filter of Fig. 5D and the circuits 56a, 56b, 55a, 55b are tuned to resonate within the pass-range of the filter of Fig. 4D. The filter of Fig. 6 is modified slightly to be developed into that of Fig. 1. Figs. 2, 3 (not shown) show the effective filters over the two ranges. Specifications 462,872 and 462,873 are referred to.
