Abstract: 1531037 Gas turbine engines - cooling systems ROLLS-ROYCE Ltd 15 Nov 1977 [24 Nov 1976] 48938/76 Heading F1G In a gas turbine engine, cooling air is bled from the combustion system and is then expanded through at least one auxiliary turbine before passing to the turbine section of the engine for cooling purposes. In the engine shown, cooling air is bled, from the combustion system indicated at 24, 25 through a circumferentially-extending opening 26, the air acting to drive turbine 27 mounted on the engine high-pressure shaft 20. The air is thereby reduced in pressure and temperature and passes in part through openings 32, 33 to cool the HP turbine rotor 17. The remaining air acts on a second turbine 28 mounted on the shaft 20, this further cooled air acting in part to cool the upstream face of the HP turbine rotor disc 29 and in part to cool the downstream face of the disc; the second part of the air passes through openings 31 in the shaft 20, the openings being inclined to the radial direction so that they function as a reaction turbine whereby the air is yet further cooled.

Title: Push-pull transistor oscillator
Inventor: PASCIUTTI EDWARD R
IPC: H02M7/53846
Filed: 1968-10-17
Abstract: 1,212,627. Oscillators. NATIONAL AERONAUTICS & SPACE ADMINISTRATION. 17 Oct.. 1968 [17 Oct., 1967], No. 49260/68. Heading H3T. A transistor oscillator, for an invertor, has an output transformer T<SP>1</SP>1, a feedback transformer T<SP>1</SP>2, and a frequency determining network 40 including a saturable reactor SR and an inductance L connected in series between windings 43, 44 on the respective transformers. From time T 0  to T 1  (Fig. 2, not shown) supposing the reactor SR to be initially unsaturated and the network 40 to have therefore a high impedance, the current i L  therein is negligibly small and the base current i B1  of the conducting transistor, say Q1, is determined solely by the turns N1, N3 of windings 34, 36 on the feedback transformer T<SP>1</SP>2. When SR saturates, the network 40 impedance falls and its current i L  rises over the time T 1  to T 2  at a rate depending upon the inductance L. The base current i B1  decreases inversely because the collector current is fixed by the load and is unchanged (and the ampereturns relation i B1 N 3  + i L N 2  = i C1 N 1  must be satisfied). The base current i<SP>1</SP> B1  becomes zero at time T 2  and Q1 is off, as i<SP>1</SP> L  reaches its limit (i C .N 1 /N 2 ) and reverses. This turns Q2 on, and energy stored in L enhances this switching. The ampere-turns relation between winding 44 of the network 40 and windings 33, 35 controlling Q2 is such as to give a high base current i B2  in Q2 (i B2 N3=i C2 N1+i<SP>1</SP> L N2), which falls during the time T2 to T3 as the current i<SP>1</SP> L  falls at a rate determined by L, until the reactor SR comes out of saturation. A constant i B2  now flows from line T3, this being the start of a cycle of operation for Q2 similar to that described above for Q1. In a modification (Fig. 5, not shown), the inductance L (60) is made variable in dependence upon the collector current from the source (29), thus producing an increase in frequency upon a fall in L to offset the decrease in frequency caused by an increase in load current (Figs. 3, 4, not shown). In a further modification (Fig. 6, not shown) for use with a low impedance, high current source, current feedback to the transistors is from the secondary of the output transformer instead of the primary. The circuits are said to reduce charge storage effects in the transistors during switching.

The novel compound 17α-(1-methylpropadienyl) - 17# - hydroxyestr - 4 - en - 3 - one is prepared from estr-4-ene-3,17-dione by reaction with an appropriate organometallic reagent to introduce the 17α-(1.methylpropadienyl) or a 17α-(1-methyl-2-propynyl) group, the latter group then being subjected to basic isomerization. The 3-oxo-#<SP>4</SP> grouping is protected during the organometallic reaction, e.g. as 3-alkoxy- #<SP>2</SP>'<SP>5</SP>(<SP>10</SP>) or 3,3-ethylenedioxy-#<SP>5(10)</SP>. The 17#- hydroxy group is protected during base isomerization, e.g. as methoxy or tetrahydropyranyloxy. When final removal of a protecting group results in the #<SP>5(10)</SP>-isomer of the desired product, acid isomerization is effected accord ingly. The novel compound is said to possess progestational activity and may be made up with carriers into pharmaceutical compositions for oral and parenteral administration.
