Filed: 1959-03-26
Abstract: 877,665. Furnace walls. WALTHER & CIE A.G. March 26, 1959, No. 10565/59. Class 51 (1). [Also in Group XIII] A straight-through forced draught boiler of the vertical type comprises a furnace chamber 16 lined with several helically wound, or sinuous groups of tubes 15 which converge at 17 and extend, preferably with a square crosssectional shape, partially into an uptake 21 which, consisting of vertical flat walls of tubing 23, contains heat transfer surfaces 28 ... 31 and, with the chamber 16, is enclosed by an inner refractory layer 18, an intermediate gas-tight sealing metal shell 19 with expansion elements 27, and an outer heat-resistant layer of lagging material 20 which may be supported by a wire mesh. A small excess pressure supplied through a branch pipe 42 leading from the pressure side of a combustion air blower 40 is maintained in the space between the shell 19 and a surrounding cylindrical gas-tight metal shell 35. The upper end of the shell 35 supports a transistion member 50 which contains dampers 38, supports a chimney 51, and accommodates the vertical gas tubes 36 of an air preheater 41. The blower 40 forces fresh air into the preheater draught box, preheated air being delivered to a burner 12 in the floor of the furnace through a thermally insulated duct 43 having expansion elements 44a. The heat-exchange surfaces 28 ... 31 are suspended from cooled fall tubes 48, the upper headers 32 for the economizer 31 being removably suspended from a cross beam 33. Observation tubes 22 are provided at the zone 17, an additional tube 46 being mounted lower down in the furnace chamber 16. Gas-tight entry doors 44 are located in the shell 35 opposite corresponding gas-tight entry doors 45 in the gas uptake 21, the boiler being supported upon a ring 10 resting on a concrete foundation 11. In a modification, the walls of the uptake 21 are formed of two parallel helically-wound tubes 54, 55, Fig. 5. At the top of a first part of the uptake 21 the lower tube 55 is brought inwards to form a two tube annular coil 56, the tubes then being sinuously bent in an horizontal plane above the annular coil 56 before being formed into a further annular coil 56. Alternate formations of annular and sinuous coils are provided until the required heating surface has been formed and then the tubes are again disposed in the form of a cylindrical helix 59. Each of two tubes 61, 62 of the economizer are bent to cruciform shape and then spiralled outwardly to descend obliquely two tube diameters to be bent again to cruciform shape and so on until the required heating surface has been made up. The tubes 54, 55 are separated by spacers 67 the helix being adjusted by an adapter 68 and the inner coils being held by a supporting ledge 70.

Title: Improvements in telephone systems
IPC: H04M7/16
Filed: 1921-04-11
Abstract: 161,573. Ges. f³r Drahtlose Telegraphie. April 12, 1920, [Convention date]. Manual exchange systems.-In a system in which high-frequency currents in inter-exchange trunks are modulated by voice currents from subscribers' lines, means are provided for starting an oscillation generator at the A-exchange when the trunk is taken into use by a plug associated with high-frequency apparatus, and for indicating the reception of high-frequency currents at the B-exchange. The ordinary, low-frequency conversations can be carried on simultaneously over the same trunk. For example, if the trunk F1, F2, is engaged in a low-frequency conversation between the subscribers T1, T3, a call from a subscriber T2 may be forwarded over the same trunk by inserting the plug St<7> in the jack B7, energizing the sleeve relay 68 which completes the filament heating circuits of the generating and detecting valves S1, E1. At the B-exchange, the high-frequency oscillations energize a tuned relay 80 to light the lamp 84. The B-operator inserts the plug St8 in the jack B8, energizing the sleeve relay 68<1> which renders the generating and detecting valves S2, E2 operative and extinguishes the lamp 84. Oscillations from the B-exchange now energize the tuned relay 80 at the A-exchange to extinguish the lamp 90 previously lighted when the plug St7 was inserted in the jack B7. The B- operator now puts through the call to the subscriber T4 by plugging into the jack B6. Plate current is supplied to the generator valves S1, S2, from direct current generators G1, G2, choke coils D0 and condensers C0 eliminating commutatornoises, and further choke coils D1 shielding the feed circuits from high-frequency currents. Speech currents are led through the transformers TS, or TS2 to opposite sides of the grid condensers GK. Oscillations are sent to line through a filtering arrangement comprising choke coils and condensers 62 to s appress undesired frequencies. Received oscilations pass through a filtering arrangement to the grid of the receiving valve E1, E2 or any other amplifying arrangement. The speech currents, free of high-frequency oscillations, are finally, transmitted through transformers TE, or TE2 to the subscriber. To prevent coupling between the receiving and transmitting valves at the same exchange, the bridge connection shown is employed, use being made of an artificial line K. Choke coils D shield the low-frequency cordcircuits from the high-frequency currents. Alarm arrangements may be provided to indicate whether the valves are properly supplied with current. The calling indicators may be operated directly by high-frequency currents or by means of an interference receiver on which separate high frequency generators are used at eachstation.

Abstract: 979,431. Centrifugal pumps. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN KOMM. GES.]. March 23, 1961 [March 23, 1960(2)], No. 10693/61. Heading F1C. A method of reducing frictional losses in a centrifugal pump for pumping liquified gases or liquids consists in introducing into gaps between one or both of the rotor faces and the housing a medium of lower density then the pumped medium so that the latter is forced out of the gaps. Alow density medium, such as hydrogen or helium, is introduced under pressure into the gaps 7, 8 between the rotor 1 and casing 3, exterior blades 5, 6 on the rotor serving to reduce gap-losses. The pressure of the low density medium may be controlled on either side of the rotor to compensate for axial thrust when running. When the auxiliary medium is at high pressure a liquid ring seal 9, of known type, may be provided on either or both sides of the rotor. For low pressure a static seal 10 suffices.
