IPC: F22B3/00
Filed: 1924-03-15
Abstract: 214,593. Siemens - Schuckertwerke Ges. April 18, 1923, [Convention date]. Compound and composite boilers. - Old lowpressure boilers are used, when new high-pressure boilers are installed, for heating the feedsupply to the new boilers and the old superheaters are used to superheat low-pressure steam. A pump 5 forces hot water from a low-pressure boiler 6 into a high-pressure boiler 2 supplying superheated steam to a high-pressure turbine 11. Exhaust from the turbine is taken through the superheater 7 of the low-pressure boiler and used for driving a low-pressure turbine 15. The furnace gases are directed through the superheater 7 before thev enter the boiler 6. Steam may be taken from the low-pressure boilers for supplying auxiliary engines.

Title: Improvements in or relating to time delay circuits
IPC: H03K5/145

Abstract: 990,069. Pulse circuits. SPACE TECHNOLOGY LABORATORIES Inc. Feb. 27, 1962 [Feb. 27, 1961], No. 7630/62. Headings H3P and H3T. A pulse-delaying circuit comprises a capacitor 38, an inductor 40 and a unilaterally conductive device 54 connected in series across a switching device such as a thyratron 12. The thyratron 12 is normally non-conductive so that the capacitor 38 is charged from the D.C. supply 20. When a trigger pulse is fed via capacitor 24 to the grid of the thyratron 12, capacitor 38 is discharged via the semi-conductor diode 54 and the thyratron 12, the discharge being made oscillatory by inductor 40. After a half cycle of current at the natural frequency of components 40, 38, the direction of current reverses, carrier storage effects in diode 54 permitting this reversal. This continues for another quarter cycle whereupon the rest of the discharge occurs at a frequency determined by the series combination of capacitor 38 and the self capacitance 52 of diode 54. The first half cycle of this oscillation produces a high voltage pulse across resistor 28 the onset of which occurs at a time equal to three-quarters of one cycle of the natural frequency of components 38, 40, after the trigger pulse fed to the thyratron 12. A circuit comprising resistor 34 and capacitor 36 having a time constant longer than the duration of one cycle of the oscillatory circuit, is provided to add a direct component to the oscillatory current so that the thyratron 12 remains conductive during negative half cycles. In Fig. 1 (not shown), the diode 54 is replaced by a further thyratron connected as a diode. In this circuit the delay period is limited to one half cycle of the main oscillatory oscillation.

[Also in Group XXX] In a device for supplying articles such as tubes of toothpaste to a cartoning machine the articles are fed to holders or containers carried by a conveyer in timed relation with the movement of the latter by a hollow member which is rotated in timed relation with the conveyer, and which has an open end for receiving an article from a supply shoot, and a lateral aperture through which the article falls by gravity at a predetermined rotational position of the hollow member, to be received by a passing container. As shown, the hollow member is a cylinder 17, Fig. 2, or 29, Fig. 6. In the first form, tubes 14 of toothpaste are delivered at suitable intervals down shoots (not shown) into the open ends of four cylinders 17, each of which is rotated at such a speed and so timed as to deliver to each fourth container 13 on the conveyer chains 12, in such manner that every container is filled after passing all the cylinders. To adjust the timing to suit different articles each cylinder is connected by a flange 18 to a mating flange 19, Fig. 6, on a driving member by bolts 22 passing through arcuate slots 21 in the flange 18. The closed end of each cylinder has a shock-absorbing pad 27.
