Abstract: 772,283. Gas turbine plant. DJORDJEVITCH, B. D. Nov. 2, 1951 [Nov. 4, 1950], No. 25743/51. Class 110 (3). A gas turbine plant comprises in combination, means for air compression with one or several intercoolers, an accumulator for storing air under pressure supplied by the air compressor means, the pressure of the air withdrawn from the accumulator being variable or maintained automatically constant, multi-stage gas turbine means having at least two portions, combustion chamber means for heating air proceeding from the accumulator or compressor or both to the first turbine portion and combustion chamber means for interstage reheating of gases passing from one to another turbine portion. In the plant shown an isothermal compressor 2, located at any suitable source of energy, is driven by a prime mover 1 utilizing the energy. The compressed air is discharged to an accumulator 13 through a pipe 17. The compressed air is drawn off through a pipe 3, which may be of any convenient length, into a heat-exchanger 4 where it is heated by the turbine exhaust gases before being further heated in a combustion chamber 5 by fuel supplied through a pipe 12. The combustion products passed to the turbine stages 6, 8, 10 driving a generator or power consumer 11. A part of the turbine power may be used to drive the compressor by arranging the units on a common shaft or on separate interconnected shafts. In one embodiment of the latter arrangement, a synchronous electric motor on the compressor shaft is connected in parallel with a synchronous electric generator on the turbine shaft. In a second embodiment of the invention, part of the air discharged from the compressor 2 feeding the combustion chamber is further compressed by an additional high pressure compressor before being supplied to the accumulator. The air supplied to the high pressure compressor and from the accumulator to the combustion chamber is automatically controlled by valves regulated in accordance with the load. Liquid, solid or gaseous fuel may be burnt in the combustion chamber. When gaseous fuel, such as natural or producer gas is used, this may also be stored under pressure.

Title: 11,12-secoprostaglandins
IPC: C07C317/46
Filed: 1975-06-17
Abstract: 9-Thia-, 9-oxothia- and 9-dioxothia-11,12-secoprostaglandins of the formula II <IMAGE> are prepared, wherein A, R<4>, R<9> and R<10> are defined in Claim 1 and m is 0, 1 or 2. If n = 0, these compounds are obtained by reacting, in optional sequence, di-tert.-butyl malonate with two different appropriate halogeno-esters in order to introduce the two side chains. The reaction product obtained is a disubstituted malonic ester. By heating this ester in the presence of a strong acid, the corresponding substituted decarboxylated malonic acid derivative is obtained. This derivative is then reacted with bromine in the presence of mercury(II) oxide, whereby the carboxyl group is replaced by bromine. The resulting substituted bromo-ester is then reacted with the alkali metal salt of a mercaptan of the formula R<9>SH, and finally the ester group is hydrolysed. To prepare 9-oxothia- and 9-dioxothia-11,12-secoprostaglandins, the 9-thia-11,12-secoprostaglandins are oxidised. The compounds exhibit a prostaglandin-like activity and may be used for the treatment of skin diseases.

Abstract: 309,204. Huebner, J., Gaebel, R. J. H., and Nuera Art Silk Co., Ltd. Oct. 6, 1927. Apparatus for making filaments.-Separation of filaments from the main bulk during spinning by the process according to Specification 303,421 is prevented or counteracted by causing the moving liquid which flows with the filaments owing to their high speed, to flow or converge towards the filaments. This can be effected by arranging in the bath a rod or rods, or a baffle or baffles of plate, V, U or other appropriate form or by raising the bottom of the bath in proximity to the filaments. In the apparatus shown in Fig. 1, a stationary rod or roller 7 is partly immersed in the coagulating liquid near the point where the filaments 6 issue from the bath, with the result that it acts as a dam or weir to the liquid moving with the threads, so that this liquid surges over the rod or roller as indicated by the arrow 8 and in doing so flows or converges towards the filaments and prevents any filaments, which have elongated more than the others, from separating from the main bulk or carries back to the main bulk any filaments, which mav have separated therefrom. In the form shown, in Fig. 2, a partition 9 extends from the underside of the rod or roller 7 to the bottom of the bath and has the effect of increasing the surge of the moving liquid. The Provisional Specification refers also to the creation of the flow or convergence of the liquid towards the filaments at another point or other points between the spinning nozzle and the point where the filaments leave the bath.
