Abstract: 401,764. Regulating steam turbines. IMFELD, K., 32, Prinzenstrasse, Cassel, Germany. May 25, 1932, No. 14897. [Class 110 (iii).] In a steam-driven vehicle condensing the exhaust at about atmospheric pressure, the auxiliary mechanism d of the condenser being driven by means consisting of or including an exhaust turbine a driven by the exhaust from the main engine, the output of the condenser and, consequently, the share of the turbine in the total heat or pressure drop is varied in accordance with the external temperature by controlling the supply of steam to the turbine. In the form shown in Fig. 2, an auxiliary turbine b assists the turbine a, and the exhaust from the former may pass to the inlet of the latter. The controlling means may consist of a rod gll of a material, such as quartz, which is insensitive to temperature changes, fixed at one end to the end of a metal tube g<1> and engaging at its free end a lever h carrying a contact l adapted to engage insulated contacts n<1>, n<11>, n<111> in the circuits of relays r<1>, r<11>, r<111> actuating valves s<1>, s<11>, s<111> in the supply conduit of the turbine a. In another form, the turbine a or b may have several groups of wheels, each group having a separate steam supply controlled by valves s<1>, s<11>, s<111>, Fig. 5, governed by the temperature changes.

Title: Improvements in or relating to the production of artificial filaments and like materials
IPC: D01D5/04
Filed: 1933-05-24
Abstract: <PICT:0420083/IV/1> Apparatus for the production of artificial filaments and like extruded materials comprises a spinning jet for the extrusion of a spinning solution into an evaporative medium and a filter member disposed in a position remote from the jet but near the heating devices situated within the spinning chamber.  As shown in Figs. 1 and 3, a spinning chamber 6 is fitted with a supply pipe 7 conducting spinning solution to a preliminary filter 8.  The solution is led from filter 8 through a connecting piece 9 and pipe 10 to a filter device 11 disposed in the corner of the cell close to the heating pipes 12.  The filtered solution returns to the connecting piece 9 through pipe 13 and is then extruded through the jet 14 to form filaments 15.  The filter member 11 comprises a long casing 20 plugged at both ends and enclosing an inner pipe 22 perforated over the lower half of its length. Filtering material 25 is secured round the perforated part of the pipe 22.  The solution is delivered first to the annular space between the casing 20 and pipe 22 so that it is heated by the surrounding air while passing down the casing and before filtration takes place.  The preliminary filter 8 may be dispensed with and replaced by a heating member for effecting heat exchange between the air in the top of the cell and the solution. The device enables the spinning solution to be heated by the air in the cell while the normal position of the jet at the top of the cell is retained, and the arrangement is such that the jet may be easily reached for attention.  The conditions may be such that the spinning solution is brought to a temperature higher than that of the air around the jet.  Specification 165,519, [Class 2 (ii)], is referred to.

Title: Improvements relating to boiler feed-water supply plants
IPC: B01D19/00
Filed: 1922-06-01
Abstract: 203,054. Babcock & Wilcox, Ltd., (Babcock & Wilcox Co.). June 1, 1922. Feed-water, heating. - To free make-up feed - water from absorbed air and gases, it is heated separately from the main feed from the condenser in an enclosed atmosphere, the vapour given off with the air and gases being condensed and returned to the heated make-up. Water entering at the top of a closed chamber 1 falls over a number of perforated plates 5 and is heated by contact with exhaust steam supplied to the chamber through a pipe 8. The air and gases liberated from the water together with steam flow through a pipe 34 to a condenser 9 traversed by tubes 11, through which the make-up water is passed before entering the heating chamber. The air and gases pass off through a valve 12, and the condensed steam returns to the heating-chamber through tubes 36. The water passes through a filter 13 to a vessel 15, in which the water is further heated by live steam admitted through a pipe 17. Vapour is led off from the vessel 15 through a pipe 151 connected to the exhaust steam supply pipe 8. The make-up flows from the vessel 15 into a tank 19, in which it is mixed with the main feed enter. ing the tank through a pipe 20. The mingled water enters a chamber 22 under reduced pressure and flows over a number of perforated plates 23. The vapour together with the air and gases drawn off from the chamber 22 pass into a condenser 25 traversed by tubes, through which the main feed flows before entering the mixing tank. Water passes from the bottom of the chamber 20 to the feed pump 6 through a pipe 27. The condenser 9 may be arranged vertically above the chamber 1. The water may be taken to the feedpump directly from the mixing-tank.

Title: Improvements in processes for the production of articles from stainless chromium-nickel steel alloys
IPC: C21D8/00
Filed: 1931-05-27
Abstract: In the production of articles such as sheets, strips or wires from austenitic chromium-nickel steel alloys, the articles are subjected to cold working such as rolling, forging, pressing or drawing and to a subsequent recrystallizing heating, after which they are cooled slowly or rapidly.  The cold working is performed at a temperature at which no recrystallization occurs, e.g. not above 950 DEG  C., and the extent of the working is to reduce the cross-sectional area by more than 15 per cent, and preferably about 50 per cent.  Practically the whole of the carbon is precipitated before the cold working operation, at a temperature of about 600-900 DEG  C. or during the operation at its specified temperature.  The temperature employed in the recrystallization heating is from 850-1020 DEG  C.  An example of an alloy to which the invention relates contains 6 per cent to 40 per cent chromium, 40 per cent to 4 per cent nickel and up to about 0,5 per cent carbon and alloys produced according to the invention are stated not to become brittle if heated to a temperature of from 500-900 DEG  C. and exposed to chemical attacks.
