Abstract: 1,182,027. Frequency discriminators. ROLLSROYCE Ltd. 12 June, 1968, No. 27822/68. Heading H3A. [Also in Division G1] A circuit for detecting a periodic frequency fluctuation superimposed on a randomly distributed train of pulses comprises a leaky integrator producing a corresponding periodic signal, means generating first and second signals when the periodic signal exceeds a first voltage and falls below a second voltage respectively and a circuit responsive to the first and second signals to produce a pulse for each cycle of the periodic signal. The train of pulses is applied through an input amplifier 50, Fig. 3, to a monostable pulse shaper circuit 52 having a time constant controlled by RV1. The shaped pulses are passed by an emitter follower 54 to a diode pump circuit 56 which produces a periodic signal with a ripple on it due to the arrival of individual pulses. The periodic signal is fed through a Darlington connected emitter follower 58 to Schmitt trigger circuits 60, 62 with their levels (adjustable by RV3 and RV4) set farther apart than the amplitude of the ripple. The negative pulse produced at the collector of TR9 as the periodic signal rises above the first level sets the bi-stable circuit 68, and the negative pulse produced at the collector of TR12 as the periodic signal falls below the second (lower) level resets circuit 68. Circuit 68 thus produces pulses at the frequency of the periodic frequency variation of the pulses applied to amplifier 50. Tachometer.-The rotational speed of a turbine shaft 14, Fig. 1, is measured by irradiating one of the bearing rollers 20a to make it gamma active. The output of a scintillation counter 22 is passed through a noise-reducing pulse height selector 30 to a circuit 34 as described above to obtain a pulse signal the frequency of which indicates the turbine speed. This signal is applied to a ratemeter 30 and oscilloscope 42 and to a counter/timer 40 and printer 44.

The air drawn by the compressor through a strainer H is discharged past a speed-governor controlled valve ,j into a pipe b which feeds a reservoir B. When a valve b<1> is closed and a valve c<3> opened the air passes through the cooling-jacket c<1> of the turbine, where it is preheated, to the jacket d, Fig. 9, of the reciprocating engine. Part then passes to a burner E through pipe d<1> and nozzle d<2>. Fuel is supplied by a pump F through pipe f. Another portion of the air is admitted to the gas stream through ports d<3>, e<4>, and the mixture passes through nozzles e, e<1> to the engine. The engine shown is of the reversible uniflow sleeve-valve type, reversal being effected by an angular adjustment of the cam-shaft by a lever n. A pipe d<10> leads the exhaust to the turbine C. The compressor A is surrounded by a cooling-jacket a<6> into which the outer ends a<5>, Fig. 5, of the stator blades project. These blades are welded at a4 into holes in the casing a<2>. The cooling fluid may be circulated through a radiator G. Compressed air from the chamber B is passed through a supplementary compressor M to the engine jackets for starting, and a heater unit K may be switched on. In a modification, the reciprocating engine, which is not reversible, drives the compressor through gearing and the exhaust turbine delivers power.

Title: Improvements in devices for light-field and dark-field illumination of microscopic objects
IPC: G02B21/12
Filed: 1932-10-08
Abstract: 389,414. Microscopes. ZEISS, C., [Firm of], Carl-Zeiss-Strasse, Jena, Germany. Oct. 8, 1932, No. 28063. Convention date, Oct. 15, 1931. [Class 97 (i).] Relates to a device for light-field and dark-field illumination of microscope objects, in which a pencil of rays may be directed to the object either by a light-field condenser or by a dark-field condenser surrounding the light-field condenser, the change of illumination being effected by means of a diaphragm. The device shown is for illumination by incident light in which the light is directed down to the object plane 10 by a reflector having an annular silvered area 12 and a non-silvered central part 11 through which the object is observed. The source of illuminating rays is the illuminated aperture of an iris diaphragm 13 behind which is a convergent lens 14 having its front focus in the plane of the diaphragm. In the rear focal plane of the lens is placed an iris diaphragm 15 adjacent to which are an aplanatic annular reflecting condenser 16 and an annular paraboloidal reflecting condenser 17, the rear focus of the condenser 16 being coincident with the front focus of the condenser 17. A convergent lens 18 is inserted between these condensers and the part 11 of the reflector and there is disposed between the reflector and the object plane 10 a dioptric condenser, shown as the microscope objective 20, for light-field illumination and an annular catoptric condenser 21, similar to the condenser 17, for dark-field illumination. For light-field illumination the diaphragm 15 is closed so that light passes only through the hollow central part of the annular condensers 16, 17 and, after traversing the lens 18 is partly reflected by the surface 11 so as to enter the objective 20. For dark-field illumination the diaphragm 15 is opened and an opaque stop 19 is placed in position 19<1> in front of the lens 18. The rays reflected by the condensers 16, 17 are then incident on the reflecting surface 12 and thereby directed to the condenser 21. For simultaneous light and dark field illumination the stop 19 is removed and the diaphragm 15 is left open. An arrangement for illumination by transmitted light is also described.
